Effect of Intracoronary Shunt on Right Ventricular Function During Off-pump Grafting of Dominant Right Coronary Artery with Poor Collateral
Although numerous studies have validated the efficacy of intracoronary shunt on reducing left ventricular dysfunction during off-pump coronary artery bypass surgery (OPCAB), there is lack of evidence supporting its role on right ventricular (RV) function during right coronary artery (RCA) revascularization. Therefore, we studied the effect of intracoronary shunt during grafting of dominant RCA ...
متن کاملInfluence of intracoronary shunt size on coronary endothelial function during off-pump coronary artery bypass.
OBJECTIVE The insertion of intracoronary shunts during off-pump coronary artery bypass surgery may induce severe endothelial dysfunction in the target arteries. The purpose of this study was to determine the role of the ratio of the shunt diameter to the target artery diameter in the development of endothelial dysfunction and to develop guidelines for selecting the most appropriate shunt size. ...
متن کاملEffects of off-pump versus on-pump coronary artery bypass grafting on early and late right ventricular function.
BACKGROUND Off-pump CABG (OPCABG) results in better preservation of left ventricular function in the perioperative period than conventional on-pump CABG (ONCABG); however, evidence is conflicting as to the effect of OPCABG and ONCABG on right ventricular (RV) function, possibly because of the complexity involved in measuring this. METHODS AND RESULTS In a single-center randomized pilot study,...
متن کاملChange in right ventricular function during off-pump coronary artery bypass graft surgery.
OBJECTIVES Hemodynamic derangement during displacement of beating heart in off-pump coronary artery bypass graft (OPCAB) surgery might be related with right ventricular (RV) dysfunction. We evaluated RV function and hemodynamic alterations using a thermodilution pulmonary artery catheter. METHODS The study included 30 patients undergoing OPCAB, using single pericardial suture and tissue stabi...
متن کاملCarbon dioxide embolism induced right coronary artery ischaemia during off-pump obtuse marginalis artery grafting.
Although use of carbon dioxide (CO2) blower has been regarded safe during off-pump coronary bypass surgery (OPCAB), we experienced a case of right coronary artery ischaemia induced by retrograde CO2 embolism originating from the opened obtuse marginalis artery during OPCAB. The spray pressure can exceed the diastolic pressure, especially during grafting at the lateral or posterior wall when hae...
