Mechanism and Immediate Outcome of Significant Mitral Regurgitation Following Balloon Mitral Valvuloplasty with JOMIVA Balloon
Journal Title: Journal of Clinical and Diagnostic Research - Year 2017, Vol 11, Issue 3
Abstract
Introduction: Balloon Mitral Valvuloplasty (BMV) with inoue balloon is the most common technique being followed worldwide. Over the wire BMV is a modified technique with Joseph Mitral Valvuloplasty (JOMIVA) balloon and is being followed in certain centres. We hypothesized that, the incidence and mechanism of Mitral Regurgitation (MR) is likely to be different from that of inoue balloon. Aim: To assess the mechanism and immediate clinical outcome of significant MR following BMV with JOMIVA balloon retrospectively. Materials and Methods: We retrospectively analyzed the outcome of 48 patients who developed moderate to severe MR out of 249 patients who underwent BMV in our institute. We analyzed the echocardiographic and clinical parameters of these patients. Results: Nineteen (7.6%) patients developed severe MR and 29 (11.2%) patients developed moderate MR. Commisural separation resulting in MR was the most common cause which was contributing to 73.6 % and 85.7% of patients with moderate and severe MR respectively. Leaflet tear was the second most common cause which contributed to 15.7% and 14.2% of patients with severe and moderate MR respectively. Chordal rupture contributed to 10.5% of patients with severe MR. Six (31.6%) patients with severe MR developed worsening breathlessness among them one had to be referred for mitral valve replacement during index hospitalization and the rest could be managed medically. Patients with moderate MR remained asymptomatic and stable. Conclusion: Severe MR following JOMIVA BMV results most commonly due to wide separation of commisures. JOMIVA balloon is less likely to cause damage to subvalvular structures than inoue balloon. Most patients who develop severe MR will not require emergency mitral valve replacement. Moderate MR is well tolerated clinically.
