Gated radionuclide cardiac blood pool scans (GCS) of end-systole and end-diastole or eight images subtending the entire cardiac cycle were performed on seven patients with left atrial myxomas documented by pulmonary cineangiography with left atrial follow-through. The ethocardiogram was either suggestive or diagnostic in all patients. In addition to demonstration of the tumor (6 patients), the ...

An 84-year-old woman with hypertension presented to our medical center with dyspnea and lower extremity edema. Electrocardiography demonstrated atrial fibrillation with a rapid ventricular response. Transthoracic echocardiography color Doppler showed abnormal flow in the region of the interatrial septum (Fig. 1A). Transesophageal echocardiography demonstrated a defect adjacent to the interatria...

OBJECTIVE The objective of our study was to determine the feasibility of early extubation and to identify the risk factors for delayed extubation in pediatric patients operated for ventricular septal defect closure. METHODS A prospective, observational study was carried out at our Institute. This study involved consecutive 135 patients undergoing ventricular septal defect closure. Patients we...

INTRODUCTION AND OBJECTIVES The incremental prognostic value of inducible myocardial ischemia over necrosis derived by stress cardiac magnetic resonance in depressed left ventricular function is unknown. We determined the prognostic value of necrosis and ischemia in patients with depressed left ventricular function referred for dipyridamole stress perfusion magnetic resonance. METHODS In a mu...

UNLABELLED Between May 1974 and December 1993, 37 patients (0.75%) with a double-chambered right ventricle underwent surgical repair. The patients ranged in age from 11 months to 12 years (mean 4 +/- 1.1 years). Cardiac catheterization was performed in 36 patients. The proximal right chamber pressure was 118 +/- 10 mmHg and the mean ventricular gradient pressure was 75 +/- 10 mmHg. A ventricula...

OBJECTIVE The aim of this study was to evaluate prognosis of types of ventricular septal defects and coexistence of associated cardiac and extracardiac defects. METHODS 120 prenatal diagnosed pregnancies associated with ventricular septal pathology were retrospectively evaluated and divided into four groups, as atrioventricular septal defects, perimembranous septal defects, muscular septal de...

INTRODUCTION AND OBJECTIVES As cardiac septal defects are frequently associated with pulmonary arterial hypertension, hemodynamic assessment is essential before deciding on surgery. The aim of this study was to evaluate the use of cardiovascular magnetic resonance imaging for assessing cardiac shunts and for quantifying pulmonary artery systolic pressure in patients with cardiac septal defects....

UNLABELLED Information on the prognostic value of noninvasive stress imaging techniques in the elderly is relatively scarce. This study assessed the prognostic value of dobutamine stress (99m)Tc-tetrofosmin SPECT for the prediction of mortality and cardiac events in elderly patients. METHODS Clinical information and SPECT results were analyzed for 272 consecutive patients > or = 65 y old (mea...

Dear Sir, Cardiac auscultation is becoming a dying clinical art. The balance between cardiac physical examination and imaging modalities in the diagnosis and delineation of congenital cardiac disease has changed significantly since the introduction of echocardiography, and more recently computed tomography, and magnetic resonance imaging, and is now leaning towards a mechanistic approach while ...
