Late gadolinium enhanced cardiovascular magnetic resonance of lamin A/C gene mutation related dilated cardiomyopathy (Journal of Cardiovascular Magnetic Resonance 2011, 13:30)

Dr. Miia Holmstrom and cols, concluded that cardiac conduction abnormalities, mildly dilated LV and depressed systolic dysfunction are common in dilated cardiomyopathy, (DCM) caused by a lamin A/C gene mutation. However, other cardiac diseases may produce similar symptoms. CMR is an accurate tool to determine the typical cardiac involvement in lamin A/C cardiomyopathy and may help to initiate early treatment in this malignant familiar form of DCM.

Sex and Race Differences in Right Ventricular Structure and Function: The Multi-Ethnic Study of Atherosclerosis–Right Ventricle Study (Circulation. 2011;123:2542-2551.)

Right ventricular (RV) morphology is an important predictor of outcomes in heart and lung disease. Dr Kauwt and cols from the John`s Hopkins Hospital examined the demographic factors associated with RV morphology and function in a population-based multiethnic sample free of clinical cardiovascular disease and concluded that age, sex, and race are associated with significant differences in RV mass, RV volumes, and RV ejection fraction, potentially explaining distinct responses of the RV to cardiopulmonary disease.

Relation of myocardial T2* to right ventricular function in thalassaemia major (EHJ,2010:31, 1648–1654)
Dr. Francisco Alpendurada and cols, supervised by Prof. Dudley Pennell from the Royal Brompton Hospital in London, have many studies about Iron Overload. One very interesting is about RV iron deposition. We can`t miss it... They concluded that myocardial iron deposition is strongly associated with RV dysfunction, which mirrors the decrease in LV function seen with worsening cardiac iron loading. Right ventricular dysfunction may play a significant role in heart failure associated with myocardial siderosis...
