Assessment Of Right Ventricular Function In Patients Undergoing Coronary Artery Bypass Graft In Assiut University

Right ventricular (RV) dysfunction is a major risk factor in coronary artery disease (CAD) and patient undergoing revascularization with this combination , incidence of RV dysfunction is reported in about 20% cases of CAD.

RV dysfunction is a possible cause of cardiac failure after cardiac surgery and has a high mortality rate.

RV dysfunction is a recognized cause of hypotension early after coronary artery bypass graft surgery (CABG)

A decrease in RV function is an event known to occur after CABG. Right ventricular dysfunction can be seen during and immediately after cardiac surgery. Although the mechanism of this phenomenon is not well understood, cardiopulmonary bypass, perioperative myocardial ischemia, intraoperative myocardial damage, cardioplegia, and pericardial disruption or adhesion have been suggested as probable causes.

Major reasons for complications of cardiac surgery are the need for hypothermic cardiac arrest, aortic cross clamping, and exposure to a cardiopulmonary bypass circuit.
