its most severe form, hypoplastic left heart syndrome, in which the left ventricle is too small to support the systemic circulation. If the left ventricle is considered to be adequate in size and structure, a strategy using catheter-directed or surgical intervention to treat the …

flow out of the heart – put another way, the stroke volume will increase. In heart failure, the ventricle can not generate a high enough pressure to expel all of the blood that is being delivered to it. If we were able to drop the aortic pressure, that will increase the pressure difference between ventricle and …
Hypoplastic Left Heart Syndrome - RSNA
Until recently, hypoplastic left heart syndrome (HLHS) was an invariably lethal pathologic con-dition. HLHS comprises a wide spectrum of car-diac malformations, including hypoplasia or atre-sia of the aortic and mitral valves and hypoplasia of the left ventricle and ascending aorta. The great vessels are normally related in HLHS. The

Hypoplastic Left Heart Syndrome . What is it? In hypoplastic left heart syndrome (HLHS), the heart’s left side — including the aorta, aortic valve, left ventricle and mitral valve — is underdeveloped. What causes it? In most children, the cause isn’t known. Some children can have other heart defects along with HLHS. How does it affect ...

Double-outlet left ventricle is a rare anomaly in which the aorta and pulmonary arteries arise completely or mostly from the morphologically left ventricle. According to this definition, double-outlet left ventricle is a very heteroge-nous entity, presenting wide variations in morphology. Thus, Van Praagh et al 1 described 14 different types, and

In the setting of acute RV myocardial infarction, elevated right-sided heart pressures result. One
