Understanding and Treating Congenital Diaphragmatic Hernia

...authors state. In addition, they suggest that left ventricular hypoplasia, commonly seen in prenatally diagnosed cases with CDH (in which the enlarged right ventricle compresses the left ventricle) is often reversible, unlike true hypoplasia in which the heart is underdeveloped. Accordingly, the diagnosis of hyp...

Aerobics Turn Enlarged Heart into a Trimmer, More Efficient Organ

...we didn't know the effects of exercise training on ventricular remodelling," Dr. Haykowsky said. The analysis showed that ejection fraction improved significantly in patients who did aerobic training (2.59 percent, on average). Similarly, the patients' enlarged hearts became significantly smaller, with a reduc...
