== Overview ==&lt;br /&gt;
Surgical procedure involving the removal of part or all of the pericardium, the fibrous sac surrounding the heart. It is primarily performed to treat constrictive pericarditis(CP)—a condition where the pericardium becomes scarred and loses elasticity, impeding normal cardiac filling and function&amp;lt;ref name=&amp;quot;:0&amp;quot;&amp;gt;{{Cite journal|last=Al-Kazaz|first=Mohamed|last2=Klein|first2=Allan L.|last3=Oh|first3=Jae K.|last4=Crestanello|first4=Juan A.|last5=Cremer|first5=Paul C.|last6=Tong|first6=Michael Z.|last7=Koprivanac|first7=Marijan|last8=Fuster|first8=Valentin|last9=El-Hamamsy|first9=Ismail|last10=Adams|first10=David H.|last11=Johnston|first11=Douglas R.|date=2024-08-06|title=Pericardial Diseases and Best Practices for Pericardiectomy: JACC State-of-the-Art Review|url=https://www.sciencedirect.com/science/article/pii/S073510972407548X|journal=Journal of the American College of Cardiology|volume=84|issue=6|pages=561–580|doi=10.1016/j.jacc.2024.05.048|issn=0735-1097}}&amp;lt;/ref&amp;gt;. The procedure aims to relieve constriction and improve cardiac output.&lt;br /&gt;
&lt;br /&gt;
Constrictive pericarditis(CP): Granulation tissue formation in and around the pericardium(protective fibroelastic sac that covers the heart). This granulation tissue results in loss of pericardial elasticity, leading to restriction in ventricular filling.  The leading cause of CP worldwide is tuberculosis. &amp;lt;ref&amp;gt;{{Cite journal|last=Albarrán|first=Ali Ayaon|last2=González|first2=José Antonio Blázquez|last3=García|first3=José María Mesa|date=2018-06|title=&amp;quot;Malignant&amp;quot; Chronic Constrictive Pericarditis|url=https://pmc.ncbi.nlm.nih.gov/articles/PMC6039145/|journal=The Eurasian Journal of Medicine|volume=50|issue=2|pages=140|doi=10.5152/eurasianjmed.2018.17358|issn=1308-8734|pmc=6039145|pmid=30002587}}&amp;lt;/ref&amp;gt;  In developed nations, the leading cause is idiopathic vs. post-viral infection.  With the fibrotic pericardial sac, ventricular filling is limited, leading to decreased end-diastolic volume and subsequently, a decreased stroke volume and cardiac output. &lt;br /&gt;
&lt;br /&gt;
The right heart does not experience the decrease in intrathoracic pressure during inspiration that is typical in healthy patients, referred to as dissociation between intrathoracic and intracardiac pressures.  This dissociation distinguishes it from cardiac tamponade.  &lt;br /&gt;
&lt;br /&gt;
Types of constrictive pericarditis:&lt;br /&gt;
&lt;br /&gt;
# Subacute CP: Early, inflammatory stage of CP.  Patients may have chest pain, pericardial effusion, elevated inflammatory markers.&lt;br /&gt;
## Transient CP: Variant of subacute CP.  Resolves spontaneously or with medical therapy in 3-6 months.  Pathophysiology is acute pericardial inflammation as opposed to permanent fibrosis and calcification(seen with chronic CP)&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
### Treatment involves treating the underlying cause of inflammation.  Examples: autoimmune disorder, infection.  &lt;br /&gt;
### Treatment includes anti-inflammatory, NSAIDs, colchicine. &lt;br /&gt;
# Effusive-Constrictive pericarditis: 1-2% of patients with pericarditis.  Cardinal finding is elevated CVP/Right atrial pressures(RAP).&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
# Chronic CP: Usually irreversible, requires radial pericardiectomy commonly.  Signs and symptoms include pericardial calcifications, a-fib, liver cirrhosis, cachexia. Low likelihood or response to medical management with anti-inflammatory medications.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
# Occult CP: Rare form of CP.  Often diagnosed after fluid bolus challenge during cardiac catheterization. &amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Indications&amp;lt;!-- List and/or describe the indications for this surgical procedure. --&amp;gt; ===&lt;br /&gt;
There are no current American Heart Association/American College of Cardiology guidelines for management of pericardial disease.  However, European counterparts(Task Force for the Diagnosis and Management of Pericardial Diseases of the European Society of Cardiology - ESC) published guidelines for treatment of pericardial diseases in 2015, which are as follows.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* Pericardiectomy is recommended in patients with chronic CP and NYHA functional class III or IV symptoms.  &lt;br /&gt;
* Pericardiectomy may be considered in patients with refractory or persistent recurrent pericarditis(RP).&lt;br /&gt;
** Patients who failed medical therapy or are intolerant to it.&lt;br /&gt;
* Pericardiectomy is recommended in patients with partial agenesis of the pericardium leading to cardiac herniation and hemodynamic compromise. &lt;br /&gt;
** Pericardial agenesis is often asymptomatic but should be monitored &lt;br /&gt;
&lt;br /&gt;
=== Surgical procedure&amp;lt;!-- Briefly describe the major steps of this surgical procedure. --&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
* TEE (transesophageal echocardiography) used intraoperatively to guide resection and assess results.&lt;br /&gt;
* CPB as a topic is beyond the scope of this article but will be discussed briefly with the general steps below&lt;br /&gt;
*# Median sternotomy&lt;br /&gt;
*# Exposure of the heart&lt;br /&gt;
*# Aortic cannulation&lt;br /&gt;
*# Right atrial cannulation&lt;br /&gt;
*# Insertion of aortic root and the LV vent&lt;br /&gt;

The procedure aims to relieve constriction and improve cardiac output.&lt;br /&gt;
&lt;br /&gt;
Constrictive pericarditis(CP): Granulation tissue formation in and around the pericardium(protective fibroelastic sac that covers the heart). This granulation tissue results in loss of pericardial elasticity, leading to restriction in ventricular filling.  The leading cause of CP worldwide is tuberculosis. &amp;lt;ref&amp;gt;{{Cite journal|last=Albarrán|first=Ali Ayaon|last2=González|first2=José Antonio Blázquez|last3=García|first3=José María Mesa|date=2018-06|title=&amp;quot;Malignant&amp;quot; Chronic Constrictive Pericarditis|url=https://pmc.ncbi.nlm.nih.gov/articles/PMC6039145/|journal=The Eurasian Journal of Medicine|volume=50|issue=2|pages=140|doi=10.5152/eurasianjmed.2018.17358|issn=1308-8734|pmc=6039145|pmid=30002587}}&amp;lt;/ref&amp;gt;  In developed nations, the leading cause is idiopathic vs. post-viral infection.  With the fibrotic pericardial sac, ventricular filling is limited, leading to decreased end-diastolic volume and subsequently, a decreased stroke volume and cardiac output. &lt;br /&gt;
&lt;br /&gt;
The right heart does not experience the decrease in intrathoracic pressure during inspiration that is typical in healthy patients, referred to as dissociation between intrathoracic and intracardiac pressures.  This dissociation distinguishes it from cardiac tamponade.  &lt;br /&gt;
&lt;br /&gt;
Types of constrictive pericarditis:&lt;br /&gt;
&lt;br /&gt;
# Subacute CP: Early, inflammatory stage of CP.  Patients may have chest pain, pericardial effusion, elevated inflammatory markers.&lt;br /&gt;
## Transient CP: Variant of subacute CP.  Resolves spontaneously or with medical therapy in 3-6 months.  Pathophysiology is acute pericardial inflammation as opposed to permanent fibrosis and calcification(seen with chronic CP)&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;

There are no current American Heart Association/American College of Cardiology guidelines for management of pericardial disease.  However, European counterparts(Task Force for the Diagnosis and Management of Pericardial Diseases of the European Society of Cardiology - ESC) published guidelines for treatment of pericardial diseases in 2015, which are as follows.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* Pericardiectomy is recommended in patients with chronic CP and NYHA functional class III or IV symptoms.  &lt;br /&gt;
* Pericardiectomy may be considered in patients with refractory or persistent recurrent pericarditis(RP).&lt;br /&gt;
** Patients who failed medical therapy or are intolerant to it.&lt;br /&gt;
* Pericardiectomy is recommended in patients with partial agenesis of the pericardium leading to cardiac herniation and hemodynamic compromise. &lt;br /&gt;
** Pericardial agenesis is often asymptomatic but should be monitored &lt;br /&gt;

## Transient CP: Variant of subacute CP.  Resolves spontaneously or with medical therapy in 3-6 months.  Pathophysiology is acute pericardial inflammation as opposed to permanent fibrosis and calcification(seen with chronic CP)&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
### Treatment involves treating the underlying cause of inflammation.  Examples: autoimmune disorder, infection.  &lt;br /&gt;
### Treatment includes anti-inflammatory, NSAIDs, colchicine. &lt;br /&gt;
# Effusive-Constrictive pericarditis: 1-2% of patients with pericarditis.  Cardinal finding is elevated CVP/Right atrial pressures(RAP).&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
# Chronic CP: Usually irreversible, requires radial pericardiectomy commonly.  Signs and symptoms include pericardial calcifications, a-fib, liver cirrhosis, cachexia. Low likelihood or response to medical management with anti-inflammatory medications.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
# Occult CP: Rare form of CP.  Often diagnosed after fluid bolus challenge during cardiac catheterization. &amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Indications&amp;lt;!-- List and/or describe the indications for this surgical procedure. --&amp;gt; ===&lt;br /&gt;
There are no current American Heart Association/American College of Cardiology guidelines for management of pericardial disease.  However, European counterparts(Task Force for the Diagnosis and Management of Pericardial Diseases of the European Society of Cardiology - ESC) published guidelines for treatment of pericardial diseases in 2015, which are as follows.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
* Pericardiectomy is recommended in patients with chronic CP and NYHA functional class III or IV symptoms.  &lt;br /&gt;
* Pericardiectomy may be considered in patients with refractory or persistent recurrent pericarditis(RP).&lt;br /&gt;
** Patients who failed medical therapy or are intolerant to it.&lt;br /&gt;
* Pericardiectomy is recommended in patients with partial agenesis of the pericardium leading to cardiac herniation and hemodynamic compromise. &lt;br /&gt;
** Pericardial agenesis is often asymptomatic but should be monitored &lt;br /&gt;

Provide a brief summary here.&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
Excision of an intracardiac tumor is a surgical procedure aimed at removing benign or malignant masses within the heart. These tumors, although rare, can interfere with cardiac function and pose risks of embolism, arrhythmia, or obstructive phenomena. Complete surgical resection is often necessary for definitive treatment and symptom relief.  Cardiopulmonary bypass(CPB) is used to arrest the heart for optimal surgical conditions.  Clinical presentation of cardiac tumors can be a triad of common symptoms: obstructive, embolic, systemic symptoms, however patients can also present asymptomatically.&lt;br /&gt;
&lt;br /&gt;
=== Indications&amp;lt;!-- List and/or describe the indications for this surgical procedure. --&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
* Intracardiac tumors causing obstructive symptoms&lt;br /&gt;
** Incidence and prevalence of cardiac tumors is one of the lowest of all solid organ tumors(0.001-0.03%)&amp;lt;ref name=&amp;quot;:0&amp;quot;&amp;gt;{{Cite journal|last=Joshi|first=Mihika|last2=Kumar|first2=Siddhant|last3=Noshirwani|first3=Arish|last4=Harky|first4=Amer|date=2020-10-01|title=The Current Management of Cardiac Tumours: a Comprehensive Literature Review|url=https://pmc.ncbi.nlm.nih.gov/articles/PMC7598975/|journal=Brazilian Journal of Cardiovascular Surgery|volume=35|issue=5|pages=770–780|doi=10.21470/1678-9741-2019-0199|issn=1678-9741|pmc=7598975|pmid=33118743}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
** Tumors are divided into neoplastic and non-neoplastic lesions&lt;br /&gt;
*** Benign neoplasm: myxoma, rhabdomyoma, fibroma, lipoma, hamartoma&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
*** Malignant primary neoplasms: angiosarcomas, rhabdomyosarcomas, lymphoma, Li-Fraumeni Syndrome&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
* Embolization risk from tumor fragments&lt;br /&gt;
** Right sided tumors embolize to the lungs resulting in PE&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
** Left sided tumors embolize to systemic circulation and can result in CVA, AKI, or peripheral arterial occlusion&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
* Arrhythmogenic potential&lt;br /&gt;
** Tumors of or in close proximity to the AV node can result in heart block&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
* Malignant or benign intracardiac masses diagnosed incidentally via echocardiography, MRI, or CT&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

== Overview ==&lt;br /&gt;
Myotomy and septal myectomy are surgical procedures used primarily to treat hypertrophic obstructive cardiomyopathy (HOCM). This condition is characterized by the thickening of the heart muscle, particularly the interventricular septum, which can obstruct blood flow.&lt;br /&gt;
&lt;br /&gt;
=== Indications&amp;lt;!-- List and/or describe the indications for this surgical procedure. --&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
* Hypertrophic obstructive cardiomyopathy (HOCM)&lt;br /&gt;
**Autosomal dominant disorder characterized by hypertrophy of the LV&lt;br /&gt;
**Symptoms: dyspnea, palpitations, arrhythmia, syncope, heart failure, stroke, and sudden death&lt;br /&gt;
** Management of this condition can be medical, electrophysiological or surgical.  This article will focus primarily on the open surgical technique&amp;lt;ref name=&amp;quot;:0&amp;quot;&amp;gt;{{Cite journal|last=Wigle|first=E.

Provide a brief summary here.&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
Tracheal resection is a surgical procedure performed to remove diseased or obstructive segments of the trachea, often to treat benign or malignant tumors, traumatic stenosis, or congenital anomalies. The affected segment is excised, and the healthy ends are anastomosed to restore airway continuity. This procedure can significantly improve airway patency and patient quality of life.&lt;br /&gt;
&lt;br /&gt;
=== Indications&amp;lt;!-- List and/or describe the indications for this surgical procedure. --&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
* Most commonly due to &amp;quot;acquired stenosis&amp;quot; typically caused by prolonged intubation or tracheostomy.&lt;br /&gt;
** Typically this stenosis is so severe and has failed attempts at ballon dilation or stenting.&lt;br /&gt;
* Malignant tumors of the trachea(&amp;lt;0.01% of all tumors, and 0.2% of respiratory tract tumors)&lt;br /&gt;
* Benign tumors causing airway obstruction&lt;br /&gt;
* Tracheal stenosis due to trauma, post-intubation injury, or radiation&lt;br /&gt;
* Congenital anomalies such as tracheal stenosis or malformation&lt;br /&gt;
* Tracheal trauma or injury repair&lt;br /&gt;
&lt;br /&gt;
=== Surgical procedure&amp;lt;!-- Briefly describe the major steps of this surgical procedure. --&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
* Patients with airway stenosis often have prexiitng tracheosotmy, which can be intubated directly with ETT.  In other cases, the procedure can be done with rigid bronchoscopy or via anterior cervical approach.&lt;br /&gt;
* Three distances must be measured when planning the resection portion of the procedure: vocal cords to the carina, distal tip of the lesion to the carina, and proximal tip of the lesion to vocal cords.&lt;br /&gt;
* The diseased segment is resected with clear margins.&lt;br /&gt;
* Resection for patients with severe subglottic stenosis high in the cervical trachea may require partial excision of the cricoid cartilage.&lt;br /&gt;
* End-to-end anastomosis is performed with absorbable sutures, ensuring tension-free closure.&lt;br /&gt;
* Consider releasing maneuvers (e.g., suprahyoid release) if tension is high.&lt;br /&gt;
* Use of intraoperative bronchoscopy&lt;br /&gt;

* The anatomic location and percentage of obstruction were assessed endoscopically and graded I to IV. (Cotten Classification&lt;br /&gt;
* Ascertain location and extent of stenosis&lt;br /&gt;
* Stenosis can be classified as ''structural'' or ''fixed''(intraluminal or extraluminal)&lt;br /&gt;
* Stenosis can be classified by ''dynamic'' vs. ''functional''&lt;br /&gt;
&lt;br /&gt;
* Rigid bronchoscopy may be used intraoperatively for airway access.&lt;br /&gt;
** Maintain spontaneous ventilation during critical phases if possible.&lt;br /&gt;

Provide a brief summary here.&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
Tracheal resection is a surgical procedure performed to remove diseased or obstructive segments of the trachea, often to treat benign or malignant tumors, traumatic stenosis, or congenital anomalies. The affected segment is excised, and the healthy ends are anastomosed to restore airway continuity. This procedure can significantly improve airway patency and patient quality of life.&lt;br /&gt;
&lt;br /&gt;
=== Indications&amp;lt;!-- List and/or describe the indications for this surgical procedure. --&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
* Most commonly due to &amp;quot;acquired stenosis&amp;quot; typically caused by prolonged intubation or tracheostomy.&lt;br /&gt;
** Typically this stenosis is so severe and has failed attempts at ballon dilation or stenting.&lt;br /&gt;
* Malignant tumors of the trachea(&amp;lt;0.01% of all tumors, and 0.2% of respiratory tract tumors)&lt;br /&gt;
* Benign tumors causing airway obstruction&lt;br /&gt;
* Tracheal stenosis due to trauma, post-intubation injury, or radiation&lt;br /&gt;
* Congenital anomalies such as tracheal stenosis or malformation&lt;br /&gt;
* Tracheal trauma or injury repair&lt;br /&gt;
&lt;br /&gt;
=== Surgical procedure&amp;lt;!-- Briefly describe the major steps of this surgical procedure. --&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
* Patients with airway stenosis often have prexiitng tracheosotmy, which can be intubated directly with ETT.  In other cases, the procedure can be done with rigid bronchoscopy or via anterior cervical approach.&lt;br /&gt;
* Three distances must be measured when planning the resection portion of the procedure: vocal cords to the carina, distal tip of the lesion to the carina, and proximal tip of the lesion to vocal cords.&lt;br /&gt;
* The diseased segment is resected with clear margins.&lt;br /&gt;
* Resection for patients with severe subglottic stenosis high in the cervical trachea may require partial excision of the cricoid cartilage.&lt;br /&gt;
* End-to-end anastomosis is performed with absorbable sutures, ensuring tension-free closure.&lt;br /&gt;
* Consider releasing maneuvers (e.g., suprahyoid release) if tension is high.&lt;br /&gt;
* Use of intraoperative bronchoscopy&lt;br /&gt;

|Airway&lt;br /&gt;
|&lt;br /&gt;
* The anatomic location and percentage of obstruction were assessed endoscopically and graded I to IV. (Cotten Classification&lt;br /&gt;
* Ascertain location and extent of stenosis&lt;br /&gt;
* Stenosis can be classified as ''structural'' or ''fixed''(intraluminal or extraluminal)&lt;br /&gt;
* Stenosis can be classified by ''dynamic'' vs. ''functional''&lt;br /&gt;
&lt;br /&gt;
* Rigid bronchoscopy may be used intraoperatively for airway access.&lt;br /&gt;
** Maintain spontaneous ventilation during critical phases if possible.&lt;br /&gt;
*** Be prepared for elective or emergent conversion to alternative airway management (e.g., cross-field ventilation).&lt;br /&gt;
