37. Restoration of normal left ventricular geometry after percutaneous mitral annuloplasty – Case report and review of literature

Surgical mitral valve intervention is not considered suitable in patients with severe functional mitral regurgitation due to severe dilated cardiomyopathy and severe systolic dysfunction. In such patients percutaneous mitral valve intervention is the next best alternative. We are presenting case report of a patient who presented with severe dyspnea progressing to orthopnea and paroxysmal nocturnal dyspnea. He was found to have severe functional mitral regurgitation and severe left ventricle systolic dysfunction. Surgical mitral intervention was not considered suitable and percutaneous mitral annuloplasty was done. At one month follow-up significant improvement in symptoms were noted with improvement in severity of mitral regurgitation severity. At six months follow-up further improvement in symptoms were noted along with significant improvement in the severity of mitral regurgitation and normalization of left ventricle geometry. At one year follow-up his symptoms further improved, left ventricle geometry remained normal and mitral regurgitation severity remained mild to moderate.Our case demonstrate that in patient with severe LV systolic dysfunction, severe mitral regurgitation and LBBB percutaneous mitral annuloplasty can obviate the need for CRT-D due to significant improvement in LV function and geometry along with regression in severity of mitral regurgitation. Improvement in mitral regurgitation severity and LV geometry started early and kept improving with excellent result at 6 and 12months
