Aim: To compare the echocardiographic results of complete sparing of mitral valve apparatus vs only posterior leaflet sparing in Mechanical Bi-leaflet Mitral valve Prosthesis replacement, in patients with Rheumatic Mitral Regurgitation with LVESD ≥ 50 mm Methods: This prospective randomized controlled trial was performed at Department of Cardiovascular Surgery, Punjab Institute of Cardiology, L...

To evaluate the prognostic significance of clinicopathological measurement in the diagnosis of acute myocardial infarction (MI) in sheep, acute MI was induced by ligation of left anterior descending coronary artery (LAD). For this purpose, twenty four healthy sheep were divided into the sham-operated or control group (group I, thoracotomy without MI) and the experimental group (group II, with M...

In order to measure the effect of a decrease in afterload on systolic time intervals, left ventricular end-systolic diameter, and left ventricular wall stress, eight healthy young persons underwent a randomised placebo controlled trial of terbutaline before and during atenolol treatment. Pre-ejection period index, left ventricular end-systolic diameter, and wall stress all decreased after terbu...

BACKGROUND Postoperative myocardial function and microcirculation of acute coronary syndrome (ACS) was assessed by myocardial contrast echocardiography (MCE). MATERIAL AND METHODS Eighty-nine ACS patients treated with percutaneous coronary intervention (PCI) were detected by MCE and two-dimensional ultrasonography before and a month later after PCI respectively. Their myocardial perfusion was e...

The left ventricular end-systolic pressure-volume relationship is a load-insensitive measure of left ventricular performance. The relationship at end-systole between left ventricular pressure and dimension is more easily obtained, but the conflicting results of previous studies make it unclear if it has the same properties as the left ventricular end-systolic pressure-volume relationship. To ad...

OBJECTIVE This study utilized Doppler ultrasonography cardiograms in patients with third-degree atrioventricular (III-AV) block to compare right ventricular apex (RVA) pacing and right ventricular outflow tract (RVOT) pacing with respect to their effects on synchronization of contraction between the two ventricles, as well as on timing of specific left-ventricular electrical and mechanical even...

Aims Rheumatic valve diseases are most common etiological valve diseases in developing countries. Urotensin II is cardiovascular autacoid/hormone and may be associated with patients of heart valve diseases. The present study was to measure plasma urotensin II concentrations in patients with left-sided rheumatic valve diseases such as mitral regurgitation (MR) and aortic regurgitation (AR), and ...

BACKGROUND HeartMate II (HM II) and HeartWare (HW) Left Ventricular Assist Devices have been successfully used in end-stage heart failure patients as a bridge to transplantation, recovery, or decision. We set out to compare their effect in off-loading the left ventricle and its geometry. METHODS The left ventricular end diastolic (LVEDD) and end systolic (LVESD) diameters were compared betwee...
