Two-dimensional Echocardiography
The Committee recommends that when the transducer is placed in the suprasternal notch that it be referred to as in the suprasternal location. When the transducer is located near the midline of the body and beneath the lowest ribs, the transducer should be referred to as in the subcostal location. When the transducer is located over the apex impulse, the Committee recommends that this be referre...
متن کاملDetection of right pulmonary artery thrombosis by two-dimensional echocardiography.
of an inadequate data base (the point of my column). I am sorry that the word "pressure" was inadvertently substituted for the word "resistance," but what has that to do with the relationship between pulmonary vasodilator treatment and patient outcome? To state that the level of PVR correlates in untreated patients with survival and, hence, to imply that reducing PVR by drugs improves survival,...
متن کاملMetastatic tumors of the heart detected by two-dimensional echocardiography.
As a result of improved chemotherapeutic regimens and cancer treatment, life expectancy has been prolonged in many patients with various systemic malignancies. Thus metastatic invasion of the heart may occur more frequently and may play a major role in the morbidity and mortality of these patients. Early detection of cardiac metastases has important therapeutic and prognostic implications, alth...
متن کاملEvaluation of combined valvular prolapse syndrome by two-dimensional echocardiography.
The patterns of aortic and tricuspid valve motion in 50 patients with mitral valve prolapse were analyzed by wide-angle, phased-array, two-dimensional echocardiography. Twelve patients (24%) had redundant aortic leaflets bulging into the left ventricular outflow tract during diastole. Eight of 12 patients had aortic regurgitation and seven of 12 had M-mode echocardiographic evidence of aortic v...
متن کاملRecognition of imperforate atrioventricular valves by two dimensional echocardiography.
The majority of hearts in which selective right or left atrial angiography shows no direct communication between one atrium and a ventricular chamber are considered to be examples of atresia of the right or left atrioventricular valves. Most patients presenting with the clinical features of tricuspid atresia have an absent right atrioventricular connection, while those with features of mitral a...
