Objective: To determine whether the process of reverse left ventricular remodelling in response to carvedilol is dependent on baseline heart rate (BHR), heart rhythm, or heart rate reduction (HRR) in response to carvedilol. Design: Retrospective analysis of serial echocardiograms in 257 patients with chronic systolic heart failure at baseline and at 12–18 months after starting carvedilol. Rever...

PURPOSE We hypothesized that gender, age, aortic root dimension, blood group and Left Ventricular End Diastolic and Systolic Diameters may have a significant correlation with the size of mechanical valve used. METHODS We included 48 patients retrospectively who had been operated at a single tertiary hospital. All patients with aortic stenosis or regurgitation were included in the study. Patie...

OBJECTIVE Identify novel prognostic factors for patients with peripartum cardiomyopathy (PPCM). DESIGN AND SETTING Prospective cohort study conducted in a single tertiary care centre in South Africa. PATIENTS 176 African women with newly diagnosed PPCM were studied. INTERVENTIONS Clinical assessment, echocardiography and laboratory results were obtained at baseline and at 6 months. MAIN...

Ilemodynamic and echocardiographic measurements were obtained in 15 patients prior to cardioversion and immediately, one, three, and five hours after ca ,dioversion of atrial fibrillation to normal sinus rhythm1z4. j ve hours after cardioversion, there was improvement in cardiac index (P < 0.005), in stroke index (P <0.005)1and i11 stroke work index (P < 04)25), but no significant change in hea...

OBJECTIVE Children with ventricular septal defects (VSD) can have chronic volume overload, which can result in changes of left heart echocardiographic parameters. To evaluate the changes before and after surgical closure, the children were divided into three groups according to the degree of mitral regurgitation (MR), and their echocardiographic characteristics were reviewed at serial follow-up...

BACKGROUND Conventional echocardiographic technique for assessment of volume status and cardiac contractility utilizes left ventricular end-diastolic area (LVEDA) and fractional area of change (FAC), respectively. Our goal was to find a technically reliable yet faster technique to evaluate volume status and contractility by measuring left ventricular end-diastolic diameter (LVEDD) and fractiona...
