Overview

There is improvement in the mortality rates for mitral stenosis by intervention by percutaneous mitral balloon valvotomy or surgery. The 2006 American College of Cardiology/American Heart Association (ACC/AHA) guidelines on the management of valvular heart disease recommended intervention in symptomatic patients with moderate to severe mitral stenosis [1].


In asymptomatic patients, intervention is recommended in moderate to severe MS and pulmonary hypertension (pulmonary artery systolic pressure >50 mmHg at rest or >60 mmHg with exercise).

When intervention is indicated in patients with rheumatic MS, the 2006 ACC/AHA guidelines recommend that Percutaneous mitral balloon valvotomy (PMBV) is preferred to surgery if the valve morphology is favorable and the patient does not have left atrial thrombus or moderate to severe (3+ to 4+) mitral regurgitation. Valve repair is performed if possible and preferred over valve replacement which has higher perioperative mortality and morbidity. Valve repair includes both open commissurotomy and placement of an annuloplasty ring after direct visualization of the valve [1].


The decision of whether valvuloplasty is superior to surgery depends on age (<60 favors valvuloplasty), and Cath/ECHO findings (e.g. LVEDP, degree of mobility, thickening and calcification). The average end result with both strategies is about 2 cm2. Moderate or greater MR (mitral regurgitation) and LA thrombus are contraindications to valvuloplasty.
