Echocardiographic and hemodynamic studies were obtained in 42 consecutive patients undergoing aortic valve replacement for isolated aortic stenosis. Concentric left ventricular (LV) wall thickening, the most common preoperative abnormality, occurred in 95% of patients. LV dilation with reduced fractional shortening was noted in approximately 25% of patients but was severe in only one patient. S...

OBJECTIVES To evaluate the frequency of early remodeling in patients of severe aortic regurgitation after aortic valve replacement and to see the incidence of early remodeling in patients with stroke volume >97 ml versus < 97 ml before aortic valve replacement. METHOD This was a prospective comparative study conducted from August 2013 to December 2014 in a tertiary care hospital. Fifty seven ...

Introduction The timing of valve surgery in asymptomatic patients with significant aortic regurgitation can be challenging. Current indications focus on symptoms and left ventricular (LV) dilation/dysfunction, but prognosis is already reduced by this time. Quantification of the regurgitation has not previously been used to guide management, likely due to the difficulty of achieving this with ec...

Bicuspid aortic valve is the most common form of congenital heart disease. It is associated with both valvular pathology and aortic disease. Aortic regurgitation caused by a bicuspid aortic valve can be corrected by surgical valve repair, which has good short-term results. However, the significant rate of aortic regurgitation recurrence found on long-term follow-up remains a problem, partly bec...

Background The most common complication of Transcathether Aortic Valve Replacement (TAVR) is aortic regurgitation (AR). Typically, this regurgitation is in the mild range, yet in a smaller subset AR could be in the moderate-severe range. Significant regurgitation is usually due to paravalvular leak due to undersizing of the valve or malposition inferiorly into the left ventricular outflow tract...

conclusions our results demonstrated the ability of pw-tdi and s/sr modalities in detection of the early subclinical abnormalities in asymptomatic patients with significant chronic ar. results ar group had significantly increased lv end systolic and end diastolic volumes, interventricular septum and posterior wall thickness compared to controls. in ar, sm and em of septal wall, sm of lateral wa...

A 51-year-old woman was admitted to our hospital with heart failure due to aortic regurgitation. Examination showed severe aortic regurgitation mainly due to cleft-like deformity of the right coronary cusp and single coronary artery. Aortic valve replacement was performed, and the deformity was seen in all aortic cusps. Histological study showed elongation of the leaflets by myofibrotic and fib...

OBJECTIVES The left ventricular (LV) response to combined pressure and volume overload [aortic stenosis (AS) and aortic regurgitation (AR)] versus pressure overload (isolated AS)has not been systematically studied. We aimed to assess LV remodeling, functional and hemodynamic consequences inpatients with mixed aortic valve disease versus patients with isolated AS. METHODS We enrolled 181 patie...
