Left Ventricular Outflow Tract Obstruction after Ross-Konno Operation
INTRODUCTION: SAM (systolic anterior motion) is defined as the dynamic motion of the anterior mitral valve leaflet to the left ventricular outflow tract (LVOT) during systole. In this study, we present a case which we encountered with significant left ventricular outflow tract obstruction (LVOTO) related to SAM and developed after Ross-Konno operation. METHOD: A 4-month, 6.2 kg girl underwent b...
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 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...
متن کاملLeft ventricular outflow tract obstruction coexisting with ventricular septal defect.
Between January 1973 and March 1982, 13 patients have been identified who had in addition to a ventricular septal defect, a discrete narrowing of the left ventricular outflow tract. Two patients had tetralogy of Fallot and one a complete atrioventricular canal defect. Two patients had previously undergone repair of a juxtaductal coarctation and one patient banding of the pulmonary artery. Eleve...
متن کامل[Dynamic left ventricular outflow tract obstruction induced by exercise].
INTRODUCTION AND OBJECTIVES Dynamic left intraventricular outflow tract obstruction occurs occasionally in patients without hypertrophic cardiomyopathy. We hypothesized that dynamic intraventricular obstruction might occur during effort in patients with angina or dyspnea without evident disease. The objective of this prospective study was to investigate: a) whether it appears with effort; b) it...
