The long-term results of aortic valve replacement were reviewed in all 88 patients with isolated aortic regurgitation and all 103 patients with isolated aortic stenosis who were operated upon at the National Heart and Lung Institute from 1963 to 1971. Survival curves were compared to determine whether any of 30 preoperative clinical and hemodynamic findings correlated with long-term survival. T...

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...

OBJECTIVE To evaluate immediate and midterm results after balloon valvoplasty in a paediatric population with congenital aortic stenosis, giving special consideration to aortic regurgitation. DESIGN Retrospective study. SETTING Two tertiary referral centres for paediatric cardiology. PATIENTS 70 consecutive patients, with an age range of 0-16.4 years. Group A infants < 3 months old (n = 2...

BACKGROUND The clinical course of bicuspid aortic valves (BAVs) is variable. Data on predictors of aortopathy and valvular dysfunction mainly focus on valve morphology. AIM To determine whether the presence and extent of the raphe (fusion site of valve leaflets) is associated with the degree of aortopathy and valvular dysfunction in patients with isolated BAV and associated aortic coarctation...

The purpose of this study was to determine the value and limitations of an updated Doppler echocardiographic measurement of the aortic regurgitant fraction derived from the comparison of forward and reverse flows in the aortic arch. The method was based on the improvements in sampling and displaying Doppler frequencies and blood velocities provided by pulsed-emission, twodimensional location, a...
