To study the results and complications of Percutaneous Balloon Mitral Valvulotomy with Transesophageal Echocardiographic monitoring in patients with symptomatic mitral stenosis. From November 1996 to November 1998, PBMV with TEE monitoring was performed in 107 patients with symptomatic mitral stenosis. There were 72 females and 35 males, aged 19 to 65 years (mean 37 .63). The mitral valve was successfully dilated in 104 patients. Immediately after PBMV, there was significant reduction of mean mitral valve gradient (17.89 ± 6.7 mm Hg to 6.21 ± 3.02 mm Hg), mean left atrial pressure (26.67 ± 6.61 mm Hg to 13.97 ± 4.7 mm Hg), mean pulmonary artery pressure (35.21 ± 13.03 mm Hg to 27.71 ± 10.31 mm Hg). Mitral valve area was increased from 0.80 ± 0.24 cm2 to 1.75 ± 0.42 cm2 and cardiac output was increased from 3.84 ± 0.97 Llmin to 4.74 ± 1.09 Llmin. Mitral regurgitation was detected in 20 patients, severe mitral regurgitaion appeared in one patient. None of these patients required emergency surgery. Cardiac tamponade was detected in one case and resolved by pericardiocentesis. TEE was well tolerated and no complications of TEE were detected. PBMV aided by TEE is safe and well tolerated.
