Valvuloarterial impedance, but not aortic stenosis severity, predicts syncope in patients with aortic stenosis.
BACKGROUND The presence of syncope in patients with aortic valve stenosis (AS) predicts a grave prognosis. However, the evaluation of AS severity has been limited to valve-specific factors such as aortic valve area and mean transaortic pressure gradient. Recently, valvuloarterial impedance (Zva) was proposed for the estimation of global left ventricular afterload. Therefore, because predictors ...
متن کاملValvuloarterial impedance in aortic stenosis: look at the load, but do not forget the flow.
The vast majority of patients with severe calcified aortic stenosis (AS) have normal left ventricular (LV) ejection fraction, even in the presence of symptoms. Nevertheless, ≈20% of patients with AS and undergoing valve surgery were found with reduced LV ejection fraction (,50%) in the last Euro Heart Survey. This characteristic is often the result of a concomitant coronary artery disease. In s...
متن کاملDoes valvuloarterial impedance impact prognosis after surgery for severe aortic stenosis in the elderly?
BACKGROUND Valvuloarterial impedance (Zva) was introduced as a prognostic measure in patients with aortic stenosis (AS). However, it is unclear whether Zva has a prognostic impact on survival after surgical aortic valve replacement (AVR) in patients with severe AS with preserved ejection fraction (EF). METHODS We retrospectively reviewed 929 consecutive patients who had AVR. We investigated 1...
متن کاملImpact of Valvuloarterial Impedance on Concentric Remodeling in Aortic Stenosis and Its Regression after Valve Replacement
BACKGROUND Left ventricle (LV) in patients with aortic stenosis (AS) faces a double hemodynamic load incorporating both valvular stenosis and reduced systemic arterial compliance (SAC). This study aimed to evaluate the impact of global LV afterload on LV hypertrophy (LVH) before and after aortic valve replacement (AVR). METHODS The study cohort included 453 patients (247 males; mean age, 64 ±...
متن کاملSUPRAVALVAR AORTIC STENOSIS IN CHILDREN REPORT OF THIRTEEN CASES
During 15 years from 1975 to 1990, thirteen cases of supravalvar aortic stenosis were admitted at the pediatrics department of Shahid Rajai Heart Hospital, Tehran. All patients were subjected to cardiac catheterization and a angiocardiography. Patients ranged in age from 3.5 years to 14 years with a mean of 8.7 years. Seventy seven percent of childen were male. Eight cases (61.5%) had Wil...
