Intravascular haemolysis and thrombocytopenia in left ventricular outflow obstruction.
Twenty-four patients with various types of isolated discrete aortic stenosis of a wide range of severity or with muscular obstruction to left ventricular outflow were studied haematologically and by cardiac catheterization and angiocardiography. Patients had haematocrits, reticulocyte, platelet, and megathrombocyte counts, serum haptoglobin, and lactic dehydrogenase performed; urine specimens w...
متن کاملLeft Ventricular Outflow Tract Obstruction
Patients with hypertrophic cardiomyopathy (i.e., asymmetric septal hypertrophy) may show obstruction to left ventricular outflow under basal conditions or with provocative maneuvers. The presence of dynamic left ventricular outflow tract obstruction in patients with concentric ventricular wall thickening (but without abnormalities of the aortic valve) has been less well appreciated. Clinical an...
متن کاملMyocardial ischemia with left ventricular outflow obstruction
We report an unusual case of a 32-year old man who was treated for a hypertrophic obstructive cardiomyopathy (HOCM) with a DDD pacing with short AV delay reduction in the past. Without prior notice the patient developed ventricular fibrillation and an invasive cardiac diagnostic was performed, which revealed a myocardial bridging around of the left anterior descending artery (LAD). We suspected...
متن کاملRecognition of Left Ventricular Outflow Obstruction.
THE PURPOSE of this paper is to summarize the clinical, hemodynamic, and angiographic aspects of valvular, subvalvular, and supravalvular aortic stenosis, with emphasis upon recognition of the more severe grades of the diseases that may require operation. A basic feature of obstruction to left ventricular outflow is the need for the ventricle to produce high systolic pressure; a systolic pressu...
متن کاملPathology of Left Ventricular Outflow Tract Obstruction.
THE anatomic sites at which obstruction to the egress of blood from the left ventricle may occur are three in number, as follows (fig. 1): the aorta, the aortic valve, and the subaortic region of the left ventricle. Obstruction in the aorta may involve one of two general areas, namely, (1) the arch or just beyond, the lesions taking the forms of classical coarctation, tubular hypoplasia, or int...
