Provide a brief summary of this comorbidity here.
Anesthetic implications
Preoperative optimization
- Increased risk of perioperative cardiovascular decompensation
Intraoperative management
- Hemodynamic goals are to maintain forward flow and decrease regurgitant volume
- Preload: normal-high to augment CO
- Afterload: low-normal to promote forward flow
- Rate: high-normal
- Rhythm: sinus (rate more important)
- Contractility: high-normal
Postoperative management
Related surgical procedures
Pathophysiology
- Hemodynamic sequelae of AI:
- LA distension > Volume overload > Subendothelial ischemia
- CHF > pulmonary edema
- RV failure > pulmonary HTN
- In acute AI, sudden increase in LV volume can induce cardiogenic shock and pulmonary edema
