[Right ventricular function during and after aortocoronary bypass]

A transient depression of right ventricule (RV) function following aortocoronary bypass operation is a common event. Occasionally, RV failure may be responsible for postoperative low cardiac output syndrome, cardiogenic shock or intracardiac right-left shunt. Understanding and monitoring of RV function is essential for proper management of patients during and after aortocoronary bypass operation.
