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...
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 mit...
Besides the standart echcardiografic parameters for mitral stenosis assessment it is necessary to inquire hemodynamic characteristics as well. The following article describes and illustrates step-by-step invasive their significance in of patients who underwent percutaneous balloon valvuloplasty.
OBJECTIVE To investigate the value of transoesophageal echocardiography in the assessment of commissural morphology and prediction of outcome after balloon mitral valvotomy (BMV). DESIGN Prospective study. SETTING Tertiary cardiac referral centre. PATIENTS 72 consecutive patients (mean age 61.3 years, range 38-89 years) referred for BMV. INTERVENTIONS Transoesophageal echocardiography w...
The cardiogram of mitral stenosis, with emphasis on right ventricular hypertrophy and P wave changes before and after mitral valvotomy has been studied previously by Mounsey (1957) and by Rodriguez Torres et al. (1959). Cardiographic evidence of right ventricular hypertrophy that recurred after valvotomy and increased when restenosis occurred has been presented by Wilcken (1960). The present st...
Introdution: Ischemic mitral regurgitation (IMR) remains one of the most complex and unresolved aspects of ischemic heart disease that the impact of percutaneous coronary intervention (PCI) on improvement of intensity of ischemic mitral regurgitation is not well clarified. Patients with coronary artery diseases and ischemic mitral regurgitation have a worse prognosis than the patients with coro...
were selected according to age, sex, cardiac rhythm, and mode of operation, the mitral valve area (MVA) was determined by cardiac catheterization in 32 patients before and 1 year following closed mitral valvotomy. There was a significantly greater increase in MVA in female patients, younger patients, and patients with sinus rhythm than in males, patients over 45 years of age, and patients with ...
