WebDynamic left ventricular outflow tract (LVOT) obstruction has traditionally been described as a hallmark of hypertrophic obstructive cardiomyopathy, and it occurs as a result of asymmetric ventricular septal hypertrophy and systolic anterior motion of the mitral valve. 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.
