A clinical case of a 14 years old white female with asthenia and easy fatigue of two months duration is presented. The two-dimensional echocardiography study has identified a tumorous and homogeneous mass filling completely the right ventricle. During the cardiac surgery and with the help of extemporaneous biopsy the real nature of the tumor was confirmed-cardiac myxoma. In this report the authors discuss the incidence of cardiac tumors and particularly cardiac myxomas and point out the rarity of isolated myxomas in the right ventricle.
A case of a 42-year-old woman with a right coronary artery fistula into the right ventricle is reported; she was asymptomatic and a continuous precordial murmur was found on physical examination. We discuss the usefulness and limitation of the Echo 2-D/Doppler findings, concerning this diagnosis, which was only definitively established by angiocardiography.
Any technique which allows "a look inside the body" without being invasive, affords major diagnostic possibilities. The application of ultrasound offers this possibility now. The purpose of this paper is to review the current status of this relatively new diagnostic method for the detection and quantification of many cardiac disorders and to outline its usefulness. It may be said that echocardiology offers "the ideal diagnostic method" of the future, particularly when one considers the low cost-benefit ratio in comparison with other diagnostic methods such as angiocardiography.
