An 87-year-old woman with critical aortic stenosis and preserved left ventricular (LV) systolic function (ejection fraction 50%) was admitted with pulmonary edema. She stabilized with medical therapy, and a decision was made to perform balloon aortic valvuloplasty as a bridge to potential transcatheter aortic valve implantation. Initially, a temporary pacemaker was inserted from the right femor...

UNLABELLED A 91-year-old man was admitted to our hospital with dyspnea and chest pain. His electrocardiogram showed ST-segment elevation in the V1-4 leads, and an emergency coronary angiogram revealed subtotal occlusion in the left descending coronary artery. A successful primary percutaneous coronary intervention was subsequently performed using aspiration thrombectomy and bare metal stent imp...

For over a decade balloon mitral valvuloplasty has been the treatment of choice for severe mitral stenosis and replaced surgical commissurotomy in many selected cases. In spite of this, balloon mitral valvuloplasty has many disadvantages. Such disadvantage might may related to the effect of left ventricular geometry which was proven to be changed in patient with rheumatic mitral stenosis. The A...

OBJECTIVES The purposes of this study were to determine the growth pattern of the pulmonary valve (PV) annulus and right heart structures in patients with critical and severe pulmonary stenosis (PS) after balloon dilation, and to determine any morphometric or hemodynamic differences between cyanotic infants with critical PS and asymptomatic infants with severe PS that may account for their vari...

The author has just written a book on the evolution of specialty Pediatric Cardiology over last 50 years [1]. intent this review is to present summary book. Because large amount material, separated into four parts. In first part, transcatheter interventions (balloon angioplasty/valvuloplasty procedures) will be appraised.

Preliminary reports have documented the utility of balloon aortic valvuloplasty as a palliative treatment for high-risk patients with critical aortic stenosis, but the effect of this procedure on cardiac performance has not been studied in detail. Accordingly, 32 patients (mean age 79 years) with long-standing, calcific aortic stenosis were treated at the time of cardiac catheterization with ba...

BACKGROUND Percutaneous retrograde nontransseptal balloon mitral valvuloplasty is a new technique developed in our institution for opening a stenotic mitral valve. This technique is based on a new, externally steerable cardiac catheter that enters the left atrium retrogradely via the left ventricle. METHODS AND RESULTS The technique was used in 86 consecutive patients (18 men and 68 women; me...
