Role of transesophageal echocardiography during balloon mitral valvuloplasty.
Transoesophageal echocardiography (TEE) was performed during balloon mitral valvuloplasty (BMV) in 40 patients of rheumatic mitral stenosis, to assess its feasibility and additional benefits. The age range was 12-35 (mean 20 +/- 6) years. Patients were in an unsedated state and the procedure was tolerated by all without any complication. High resolution images of the interatrial septum and the puncture assembly were obtained which guided the septal puncture. In eight (20%) patients, puncture assembly had to be readvanced into superior vena cava and withdrawn down to obtain a satisfactory position for puncture. In 2 additional cases, the puncture assembly was redirected towards the fossa ovalis region under TEE guidance alone to obtain a successful septal puncture. TEE was not found useful in either negotiating the mitral valve or positioning the balloon catheter across it.
