Comparison of results of percutaneous transvenous mitral valvotomy using single (Inoue) and double balloon techniques.

This study reports the clinical presentation and course of 87 adult patients with severe Mitral Stenosis who underwent percutaneous transvenous mitral valvotomy and compares the results of 61 patients using the double balloon technique. Review of demographic and clinical baseline echocardiographic and hemodynamic data of both groups showed comparability of patients from both groups. Successful valvotomy was performed in 90% of patients with an overall mortality rate of 1.2%. Immediate hemodynamic improvement was achieved and all results were optimal usingg either technique i.e. mitral valve areas ranging from 0.71-1.9cm2 and mitral valve area index ranging from 0.71-2.26 cm2/m2. An incidence rate of 41% for postvalvotomy occurence of and/or increase in degree of mitral regurgitation was reported in both groups. The rate of complications like cardiac tamponade, embolic strokes, and significant interatrial septal defect was similar between both groups. The following trends were noted: (1) unsuccessful valvotomy and occurrence of worsening of mitral regurgitation were correlated with smaller mitral valve areas, higher mean pulmonary and left atrial pressures, (2) occurrence of atrial septal defect was correlated with higher number of inflations, older age and atrial fibrillation. The Inoue technique was found to be more cost-effective.
