Sex Dimorphism in the Myocardial Response to Aortic Stenosis.
OBJECTIVES The goal of this study was to explore sex differences in myocardial remodeling in aortic stenosis (AS) by using echocardiography, cardiac magnetic resonance (CMR), and biomarkers. BACKGROUND AS is a disease of both valve and left ventricle (LV). Sex differences in LV remodeling are reported in AS and may play a role in disease phenotyping. METHODS This study was a prospective ass...
متن کاملMyocardial contractility and afterload in aortic stenosis
Background In aortic stenosis(AS) with normal left ventricular ejection fraction(LV EF), circumferential and longitudinal systolic strains(CSt, LSt) are reduced but the underlying mechanisms are uncertain. Conventional indices of afterload(A) per unit of myocardium are suboptimal for strain analysis and based on inaccurate assumptions about myocardial properties, while conventional contractilit...
متن کاملAsymmetric myocardial thickening in aortic stenosis
Background Asymmetric wall thickening has been observed in aortic stenosis (AS) but the clinical importance is poorly understood. We hypothesized this pattern was associated with advanced remodeling and worse outcomes. Methods Left ventricular volumes, wall thickness and mass were assessed in 166 patients (70 [64, 76] years; 69% males) with cardiovascular magnetic resonance. Diffuse myocardial ...
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...
متن کاملSex Differences in the Utilization and Outcomes of Surgical Aortic Valve Replacement for Severe Aortic Stenosis
BACKGROUND Studies assessing the differential impact of sex on outcomes of aortic valve replacement (AVR) yielded conflicting results. We sought to investigate sex-related differences in AVR utilization, patient risk profile, and in-hospital outcomes using the Nationwide Inpatient Sample. METHODS AND RESULTS In total, 166 809 patients (63% male and 37% female) who underwent AVR between 2003 a...
