Introduction:Gated myocardial perfusion SPECT has diagnostic and prognostic values in coronary artery disease (CAD). We tried to determine prognostic values of the left ventricular perfusion & functional indices as well as transient left ventricular dilation (TID) derived from gated myocardial perfusion SPECT. Methods: 1820patients who underwent gated myo...

A 47 year-old female died after mitral valve replacement. Post-cardiopulmonary bypass right ventricle was not able to pump despite good left ventricular contractility. At microscopic examination, diffuse right ventricular fatty infiltration was found. We found no previous report of this pathology in patients with mitral stenosis

Echocardiographic (echo) measurements of left ventricular ejection phase indices--ejection fraction, percent shortening of the minor diameter (%deltaD), and velocity of circumferential fiber shortening (Vcf)--are said to be accurate reflections of their angiographic (angio) counterparts. Most studies correlating echo and angio left ventricular function parameters have included relatively few pa...

Background: Left ventricular torsion is one of the most important biomechanical parameters of heart that routinely is measured in short axis view.  A review of the literature has indicated that assessment of left ventricular torsion in short axis view has some limitations. In the present study, we evaluated whether torsion angle assessment in long axis view can be used as a diagnostic biomechan...

Background Heart failure (HF) in infants and children with congenital heart disease (CHD) is a crucial complication with different outcomes. Many biomarkers are used as prognostic indicators. Soluble ST2 (sST2) is one of these markers studied in adults with HF. We aimed to study the prognostic value of sST2 in CHD children with HF. Materials and Methods In current case-control study, thirty-six...

background: there is some evidence indicating improvement in myocardial performance after atrial septal defect closure, either device closure or surgical, but ventricular dyssynchrony has not been evaluated before and after surgical closure. the aim of this study was to evaluate ventricular mechanical dyssynchrony in patients with atrial septal defect before and after surgical closure. methods:...
