Takotsubo cardiomyopathy and left ventricular outflow tract obstruction.
Takotsubo cardiomyopathy often presents to the cardiac catheterization laboratory masquerading as acute ST-elevation myocardial infarction (STEMI). Some of these patients present in shock secondary to dynamic left ventricular outflow tract (LVOT) obstruction. The typical patient is an elderly, hypertensive female with sigmoid deformity of the intraventricular septum. The management of hemodynam...
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 کاملLeft ventricular outflow tract obstruction and Takotsubo syndrome: A heretofore unsettled pathophysiologic association.
A 76-year-old woman with a medical history notable for factor V gene mutation (with a previous episode of deep venous thrombosis and pulmonary embolism), arthritis and hypertension, on full-dose aspirin (325mg daily) and lisinopril and hydrochlorothiazide (unknown doses), presented in the emergency room complaining of typical 5/10 chest pain, nausea and diaphoresis. She had spent over 5 h garde...
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 کاملManifestation of Latent Left Ventricular Outflow Tract Obstruction in the Acute Phase of Takotsubo Cardiomyopathy
Objective Left ventricular outflow tract (LVOT) obstruction is a complication in 15-25% of patients with Takotsubo cardiomyopathy and sometimes leads to catastrophic outcomes, such as cardiogenic shock or cardiac rupture. However, the underlying mechanisms have not been clarified. Methods and Results We experienced 22 cases of Takotsubo cardiomyopathy during 3 years, and 4 of these 22 cases wer...
