WebStudies [ 18, 20] have shown that evidence of microvascularization obstruction on MRI is predictive of left ventricular remodeling and poor functional recovery (Fig. 9A, 9B, 9C, 9D, 9E ). The mechanisms by which no-reflow phenomenon influences left ventricular remodeling are unknown. WebA ventricular outflow tract obstruction is a heart condition in which either the right or left ventricular outflow tract is blocked or obstructed. These obstructions represent a spectrum of disorders. Majority of these cases are congenital, but some are acquired throughout life. [1] Different types [ edit]
