A meta-analysis of adjusted observational studies for mortality in transapical versus transfemoral aortic valve implantation.

This study sought to identify the prevalence of risk factors for atrial fibrillation and stroke in a sleep apnea population. ⋯ Patients with severe sleep apnea have a higher prevalence of risk factors for atrial fibrillation and stroke when compared with subjects without sleep apnea.

The association between contrast-induced acute kidney injury (CI-AKI) and chronic kidney disease (CKD) in patients with acute coronary syndrome (ACS) treated with percutaneous coronary intervention (PCI) has not been fully reported. We evaluated the association of CI-AKI on cardiovascular events in ACS patients with CKD. ⋯ CI-AKI was revealed to be a significant incremental predictor of cardiovascular events at each stage of CKD in ACS patients.

Comparative Study Observational Study
Isolated hypertrophy of the basal ventricular septum: characteristics of patients with and without outflow tract obstruction.
Isolated basal septal hypertrophy (IBSH) of the left ventricle (LV) is not a well understood phenomenon, particularly in the presence of concomitant left ventricular outflow tract obstruction (LVOTO). We evaluated the prevalence of IBSH and compared those with and without LVOTO. ⋯ IBSH is common in elderly patients referred for echocardiography. LVOTO occurs only when concomitant mitral valve co-aptation and LV hypercontractility facilitate development of a gradient, rather than through differences in the degree of BS myocardial hypertrophy.
