Mitral valve repair or replacement

Mitral valve repair or replacement

Anesthesia type	General
Airway	ETT
Lines and access	PIV, Arterial line, Central line, +/- PA catheter
Monitors	Standard ASA, arterial line BP, CVP +/- PAP, TEE, NIRS
Primary anesthetic considerations
Preoperative	-Severity and mechanism of lesion (MS vs MR, primary vs secondary) -LV size and systolic function -Pulmonary HTN, RV function -Chronic atrial fibrillation -Thromboemoblism risk (LA thrombus) -Concomitant procedures (CABG, MAZE, multi valves)
Intraoperative	-Hemodynamic goals (MS vs MR) -Full heparinization before CPB -Myocardial protection and de-airing -Conduction disturbances -Weaning from CPB: LV/RV function, valve seating, gradients
Postoperative	-RV failure -SAM -Atrial fibrillation -Low cardiac output syndrome -Bleeding

Mitral valve repair or replacement is performed for severe mitral regurgitation (MR), mitral stenosis (MS), or mixed disease. Repair is preferred when possible because it preserves annular-ventricular continuity, maintains LV geometry, improves long-term survival, and avoids prosthetic complications. Replacement is performed when repair is not durable or technically feasible (severe calcifications, rheumatic disease, extensive endocarditis).

Overview

Indications

• Symptomatic severe primary MR
• Severe secondary MR with persistent symptoms despite GDMT
• Severe MS with symptoms or pulmonary hypertension
• Endocarditis with structural destruction
• Concomitant need during CABG or other valve surgery
