Ejection load changes in aortic stenosis. Observations made after balloon aortic valvuloplasty.
To investigate complementarity and competitiveness between the intrinsic and extrinsic components of the total left ventricular systolic load, hemodynamic data from 18 elderly subjects with severe aortic stenosis were analyzed before and after balloon dilation of the stenosed aortic valve. Multisensor micromanometric pressure measurements allowed calculation (simplified Bernoulli equation) of t...
متن کاملAortic valve reinterventions after balloon aortic valvuloplasty for congenital aortic stenosis intermediate and late follow-up.
OBJECTIVES the aim of this study was to evaluate the long-term results of transcatheter balloon aortic valvuloplasty, the preferred treatment for congenital aortic stenosis (AS). BACKGROUND aortic valve function and reintervention late after this procedure are not well characterized. METHODS from 1985 to 2008, 563 patients underwent balloon dilation for congenital AS. After excluding those ...
متن کاملIn-Hospital Mortality after Balloon Aortic Valvuloplasty
With increasing life expectancies, the burden of aortic valve disease continues to be a major contributor to morbidity and mortality, affecting millions of elderly people [1,2]. Aortic stenosis (AS) begins with a long asymptomatic period [3]. Once symptomatic, survival becomes poor unless the outflow obstruction is relieved [4-6]. Retrospective studies have shown that if the patient experiences...
متن کاملLeft ventricular remodeling and improvement in diastolic function after balloon aortic valvuloplasty for congenital aortic stenosis.
BACKGROUND In congenital aortic stenosis, chronic pressure load has detrimental effects on left ventricular (LV) systolic and diastolic function. Reduction in LV pressure load with balloon aortic valvuloplasty (BAVP) may improve diastolic function. METHODS AND RESULTS Echocardiographic and catheterization data for 25 consecutive patients undergoing BAVP for congenital aortic stenosis were ret...
متن کاملBalloon Aortic Valvuloplasty
Following the description by Lababidi in 1983 of balloon aortic valvuloplasty, it has been adopted by several groups of workers for relief of aortic valve stenosis. The indications for the procedure are peak-to-peak systolic pressure gradients in excess of 50 mmHg with symptoms or ECG changes or a gradient greater than 70 mmHg irrespective of the symptoms or ECG changes. One or more balloon dil...
