Abstract

To evaluate the relationship between delayed hyper-enhancement of the myocardium and global and regional cardiac abnormalities in hypertrophic cardiomyopathy (HCM) with asymmetrical septal hypertrophy using magnetic resonance (MR) imaging. Twenty-three patients with HCM with asymmetrical septal hypertrophy were examined using a 1.5-T MR unit. Contrast-enhanced inversion-recovery gradient-echo imaging was performed to observe the myocardial damages associated with HCM. Balanced steady-state free precession imaging was performed to assess regional wall abnormalities and ejection fraction, and black-blood fast spin-echo imaging was performed to assess left atrial diameter. Delayed hyper-enhancement of the myocardium was primarily observed in the interventricular septal wall. Septal walls with the higher transmural extent of delayed hyper-enhancement were significantly thicker at end-diastole and end-systole (P < 0.05), and tended to show a decreased percentage systolic wall thickening (P = 0.079). There were no differences in theses values between non-enhancing septal walls and septal walls with the transmural extent < 50%. The high transmural extent of delayed hyper-enhancement of the myocardium may reflect the severe myocardial ...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
