“…In addition, several investigators have attempted to define the features that might be useful in distinguishing echocardiograms of patients with congestive cardiomyopathy from those of patients with Coronary artery disease [1,5,7,9,15,17]. The common echocardiographic characteristics of congestive cardiomyopathy include increased left ventricular dimensions, reduced excursion of both the Septum and left ventricular posterior wall, deCreased velocity of circumferential fiber shortening (Vcf), and posterior displacement of the mitral Valve.…”

Anomalous origin o f the left c o r o n a r y artery from the p u l m o n a r y artery is a rare congenital heart defect accounting for less than 0.5% o f patients with COngenital heart disease [3]. Early diagnosis is important for optimal medical and surgical management. Traditionally, the triad of congestive heart failure, significant cardiomegaly without a murmur, and electrocardiographic evidence o f ischemia or infarction has strongly suggested the diagnosis of rted in part by Research Fellowship Award 1 F32 HL-05675-01~ and by research grant HL-12738-092 from the National Heart, Lung, and Blood Institute, United States Public Health Service.Address reprint requests to: Ehud Krongrad, MD, Department of Pediatrics, Columbia Presbyterian Medical Center, 3975 Broadway (BHA 1-102), New York, NY 10032, USA Materials and MethodsClinical Data. Observations were made in four infants who were referred for cardiac evaluation to Babies Hospital, Columbia Presbyterian Medical Center. The initial clinical and pertinent cardiac catheterization data are given in Table 1. All the patients were in severe congestive heart failure. Only one infant had an apical murmur of mitral insufficiency. Chest x-ray films showed striking cardiomegaly and pulmonary vascular congestion.The presenting electrocardiogram was abnormal in all four patients. Common features were deep Q-waves in leads 1 and AVL and signs of left ventricular ischemia or infarction. In addition, there was evidence of left ventricular conduction delay with a QRS duration of 0.08 to 0.09 sec. and a slurred or notched upstroke of the R wave in V5 and V6 in each case. The electrocardiogram from patient 2 is representative (Fig. 1). Echocardiograms were performed at the time of initial evaluation.Cardiac catheterizations were also performed, and the diagnosis of anomalous left coronary artery arising from the pulmonary artery was confirmed in each patient. Left ventricular function was uniformly impaired with high left ventricular end-diastolic pressures and markedly decreased ejection fractions. A left-to-0172-0643/79/0001-0023 $01.20

“…Problems in diagnosis often arise, when it may be difficult to distinguish at the bedside between endomyocardial fibrosis (EMF), constrictive pericarditis, rheumatic valvular disease, and congestive cardiomyopathy (Falase, Kolawole and Lagundoye, 1976). Congestive cardiomyopathy and rheumatic valvular disease can be distinguished by their echocardiographic patterns (Millward et al, 1973;Segal, Likoff and Kingsley, 1966), and by cardiac catheterization and angiography. Constrictive pericarditis and right-sided EMF on the other hand have similar haemodynamic patterns (Somers et al, 1968).…”

Summary Twenty-one patients with endomyocardial fibrosis (EMF) and right ventricular involvement were studied by M-mode echocardiography. All 21 patients showed echocardiographic findings consisting of (i) increased right ventricular dimension, (ii) paradoxical septal motion, (iii) increased right ventricular outflow dimension (iv) thickening of the right ventricular anterior wall with increased right ventricular anterior wall motion, and (v) easily recordable tricuspid valve. In addition, some of the patients had posterior pericardial effusion, and fine fluttering of the tricuspid valve. EMF was diagnosed clinically in all the patients, haemodynamically and angiographically in 15 and confirmed at autopsy in one. None of these echo findings was present in two patients with constrictive pericarditis, and two patients with massive ascites due to portal hypertension.
