For example, the RV is considered a passive chamber because early functional recovery follows its exclusion by the Glenn (superior vena cava to pulmonary artery) or Fontan (pulmonary artery to right atrium) procedures [94,95]. Yet this 11. Right Ventricular Function Right ventricular failure is ...

The heart consists of four cavities, separated from each other by walls and valves. The blood enters the heart in the right atrium via the superior vena cava (upper part of the body) and the inferior vena cava (lower part of the body). Both vessels have no valves. The wall of the ...
