Abstract

Concomitant occurrence of pulmonary embolism and right ventricular infarction is rare. It poses important diagnostic and therapeutic implications. A case of pulmonary embolism with isolated right ventricular anterior wall infarction presented with ventricular tachycardia. One pathology could have led to the other. Two-dimensional echocardiography was useful in documenting pulmonary artery hypertension as well as regional wall motion abnormality of the right ventricle. Thrombolytic therapy and dobutamine infusion were useful. Nitrates, fluid infusion and diuretics should be used cautiously.

Abstract

A case of exercise induced ST segment depression preceding ST segment elevation in precordial leads and persistent ST segment depression in inferior leads is reported. Such an exercise response should suggest significant fixed coronary stenosis in addition to coronary spasm.

Abstract

Background: The effect of surgical closure of atrial septal defect (ASD) on biventricular functions is not well studied. We studied effect of surgical closure of ASD on bi-ventricular functions. Methods: Patients undergoing surgical closure of ASD from December 2007 to June 2009 had 3 sequential echocardiograms examination: pre-procedure, post surgery at 1-month and at 6-month of follow up. Pulse Doppler velocities across mitral and tricuspid valves were measured as peak early diastolic (E wave) and peak late diastolic (A wave). Tissue Doppler velocities across lateral wall of both right ventricle (RV) and left ventricle (LV) were measured as peak early diastolic (E′), peak late diastolic (A′), and peak systolic (S′) wave. Radionuclide angiography was performed to assess RV and LV ejection fraction at baseline and at 1-month follow up. Results: The mean age of 20 enrolled patients was 21.85 ± 10.9 years; 8 females & 12 males. Trans-tricuspid flow velocities significantly decreased following surgery at one and 6-month (p
