Influence 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 کاملImpairment of coronary flow reserve and left ventricular function in the brain-dead canine heart.
OBJECTIVE The mechanisms of cardiac dysfunction after brain death, which are thought to be mainly associated with massive catecholamine release, have not been fully elucidated, especially with respect to the coronary circulation. The aim of this study was to investigate the changes in function of the coronary artery and its contribution to hemodynamic deterioration in a canine brain death model...
متن کاملEffect 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 کاملLeft ventricular aneurysmectomy with continuous beating heart: early results
Objective: Operative mortality after left ventricle aneurysmectomy is close to 15%. Specifically for this procedure, forms of myocardial protection have been little discussed. The purpose of this study was to evaluate immediate results of left anterior ventricular aneurysmectomy using the beating heart approach. Method: We performed a retrospective analysis of 34 patients who underwent a left a...
متن کاملCoronary Flow and Left Ventricular Function during Environmental Stress
A canine model was used to study the effects of different environmental stresses on the heart and coronary circulation. The heart was surgically instrumented to measure coronary blood flow, left ventricular pressure, and other cardiovascular variables. Coronary flow was recorded by telemetry. Physiologic data were processed and analyzed by analog and digital computers. By these methods the phys...
