WebJun 16, 2015 · In patients with hypertrophic cardiomyopathy and left ventricular outflow tract (LVOT) obstruction, but without basal septal hypertrophy, we sought to identify mitral valve (MV) and papillary muscle (PM) abnormalities that predisposed to LVOT obstruction, using echo and cardiac magnetic resonance. Methods and Results— WebThe purpose of this study was to investigate the diagnostic performance of quantitative parameters generated from dynamic myocardial perfusion CT for assessment of acute myocardial infarction (AMI) and microvascular obstruction (MVO) using cardiac MRI as a reference standard.

Weba dynamic obstruction in the left ventricular outflow tract. Accelerated blood flow is triggered by hyperdynamic circulation and hypertrophy of the septum (6). The anterior mitral valve leaflet and septum constitute the outflow tract and it is the relationship between the two that is integral to understanding the mechanism of a dynamic obstruction. WebThose with significant obstruction may have an audible cardiac murmur, symptoms of congestive heart failure, and electrocardiographic changes consistent with myocardial hypertrophy or ischemia. This chapter focuses on the prevalence, physiology, clinical findings, and management of left-sided obstructive lesions including hypoplastic left heart ...
