bailon mitral valvuloplasty and closed mitral valve conunissurotomy were performed in 450 and 127 patients, respectively. also, 254 patients with severe mitral stenosis were enrolled in a prospective randomized trial comparing the two procedures. immediately after balloon mitral valvuloplasty, mean left atrial pressure was 11.38±3.54 mmhg, transmitral valve gradient was 1.8±2 mmhg, and mitral v...

Tsung O. Cheng, MD, Professor of Medicine, George Washington University, Washington, D.C. (USA) I read with interest the article on the use of transesophageal echo-cardiography (TEE) in monitoring emergency percutaneous balloon mitral valvuloplasty (PBMV) in a patient with massive left atrial thrombosis by Chirillo et al. [1]. Although I agree that TEE was of great value in monitoring each step...

A novel, transhepatic approach to mitral valvuloplasty is described in a patient with an inferior vena caval filter. After transhepatic transseptal puncture, an Inoue dilatation catheter was passed through the hepatic parenchyma and across the atrial septum. Balloon mitral valvuloplasty was performed without complications. This approach should be considered when femoral venous access is restric...

A 3-yr-old intact female snow leopard (Uncia uncia) was evaluated for progressive apathy, lethargy, and decreased appetite. Cardiac auscultation revealed a left basal grade IV/VI systolic ejection murmur, and an echocardiogram confirmed a severe pulmonic valvular stenosis (pressure gradient of 98 mm Hg). The lesion was managed by balloon valvuloplasty, resulting in a marked pressure gradient re...

Congenital pulmonic stenosis (PS) rarely presents in patients over the age of 55 years. A stable asymptomatic course into late adulthood is the usual history of mild to moderate PS. Balloon valvuloplasty has become the procedure of choice for congenital PS, especially in children and young adults. There are rare reports of its use in older adults. Significant valve calcium is believed to limit ...

Percutaneous pulmonary valvuloplasty was performed in 27 patients with congenital pulmonary valve stenosis. A fall in the transvalve gradient of at least 15 mm Hg occurred in 22 patients. In five there was little change in the severity of the stenosis; in three of these the pulmonary valve was dysplastic. None of the successfully treated patients had a dysplastic valve. The two other failures, ...

The aim of this study was to investigate the characteristics and outcomes of treating pulmonary stenosis with percutaneous valvuloplasty, and to compare them among three childhood age groups. All children under 15 years of age who had undergone pulmonary valve balloon valvuloplasty in Madani Heart Center from 2005-2009 were enrolled in this study. Data were analyzed using IBM SPSS software (SPS...
