Abstract
Background. Cardiac surgery carries a well-known risk of perioperative myocardial infarction (MI), which is associated with high morbidity and both in-hospital and late mortality. The rapid haemodynamics deterioration and presence of myocardial ischemia early after cardiac surgical operations is a complex life-threatening condition where rapid diagnosis and management is of fundamental importance. Objective. To analyse the factors associated with mortality of patients with postcardiotomy MI and to study the role of emergency coronary angiography in management and outcome. Methods. We retrospectively enrolled adult patients diagnosed to have postcardiotomy MI and underwent emergency coronary angiography at our tertiary care hospital between January 2016 and August 2019. Results. Sixty-one patients from consecutive 1869 adult patients who underwent cardiac surgeries were enrolled in our study. The studied patients had a mean age of 49 ± 16.2 years with a mean BMI of 29.5 ± 6.6 and 65.6% of them were males. As compared to the survivors group, the nonsurvivors of perioperative MI had significant preoperative CKD, postoperative AKI, longer CPB time, frequent histories of previous PCI, previous cardiotomies, pre and postoperative ECMO use, higher median troponin I levels, higher peak and 24 hours median lactate levels. Regression analysis revealed that reoperation for revascularization (OR: 23; 95% CI: 8.27–217.06; P=0.034) and hyperlactataemia (OR: 3.21; 95% CI: 1.14–9.04; P=0.027) were independent factors associated with hospital mortality after perioperative MI. Hospital mortality occurred in 25.7% vs 86.7% (P<0.001), AKI occurred in 37.1% vs 93.3% (P<0.001), haemodialysis was used in 28.6% vs 80% (P=0.002), and mediastinal exploration for bleeding was performed in 31.4% vs 80% (P=0.006) in the PCI and reoperation groups, respectively, while there were no significant differences regarding gastrointestinal bleeding, cerebral strokes, or intracerebral bleeding. The median peak troponin level was 795 (IQR 630–1200) vs 4190 (IQR 3700–6300) (P<0.001) in the PCI and reoperation groups, respectively. Absence of significant angiographic findings occurred in 18% of patients. Conclusions. Perioperative MI is associated with significant morbidities and hospital mortality. Reoperation for revascularization and progressive hyperlactataemia are independent predictors of hospital mortality. Emergency coronary angiography is helpful in diagnosis and management of perioperative MI.

Abstract
BACKGROUND Despite technical advances in coronary artery bypass grafting (CABG), early postoperative myocardial ischaemia still remains a challenging problem. The aim of this study was to determine the incidence, clinical features, angiographic characteristics, and management of early graft failure in the present CABG era. METHODS Between January 1997 and December 2002, 1731 patients underwent CABG at our institution. Coronary angiography was performed in patients with clinical evidence of early postoperative ischaemia (</=3 months). Thirty of these patients with graft failure constituted the population of this study. RESULTS Off-pump and on-pump CABG were almost evenly performed in these patients [n=16 (53%) and n=14 (47%) respectively]. Acute myocardial infarction and unstable angina were the leading indications for coronary angiography in the majority of patients [n=28 (93%)]. The most common cause of graft failure was occlusion / thrombosis [n=20 (67%)]. Percutaneous coronary intervention (PCI) was offered to the majority of patients [n=22 (73%)]. Of these patients, 14 underwent PCI to native coronary arteries, whereas eight underwent PCI to the culprit vessel. Three patients underwent reoperation, and five received medical management. Four patients (13%) died in hospital (two after redo CABG, one after unsuccessful PCI, and one patient managed medically). Two patients (7%) had nonfatal major complications (one non-ST-elevation myocardial infarction and one stroke). CONCLUSION Early graft failure generally presents as acute coronary syndrome. Graft occlusion/ thrombosis is the leading cause of ischaemia. Patients with graft failure can undergo PCI with a relatively low risk, but the need for redo CABG in associated with a high mortality.

Abstract
BACKGROUND With continuing technical advances in percutaneous coronary interventions (PCI) for coronary artery disease (CAD), patients undergoing coronary artery bypass surgery (CABG) often have complex coronary anatomy that is not ideal for PCI. Because of the complex anatomy, these patients have a higher risk of early graft occlusion. The feasibility of PCI in the treatment of early graft occlusion is not well established. METHODS A retrospective chart review was performed of patients presenting with recurrent ischemia within three months post-CABG and at one-year follow-up. RESULTS Forty-six patients with 156 grafts were identified. Three presented with STEMI, 21 with NSTEMI, 21 with unstable angina, and one with congestive heart failure. Sixty-three grafts were occluded or stenosed (>70%). Twenty-seven grafts (43%) in 17 patients were not amenable to PCI. The other 34 grafts (54%) in 23 patients underwent successful PCI. PCI was performed upon native vessels and occluded grafts with equal frequency. Six patients had patent grafts. At one-year follow-up, six of 23 patients in the PCI group were readmitted with ischemia; five vessels (14%) in four patients had restenosed. There were no deaths. In the group with no PCI, 11 of 23 patients were readmitted with ischemia with one death. CONCLUSION PCI for early post-CABG occlusion was safely performed in slightly more than half of target vessels. PCI was performed upon native vessels and occluded grafts with equal frequency. After initial PCI success, the clinical target vessel restenosis rate was 14% at one-year follow-up.

Abstract
BACKGROUND Despite decreasing rates of acute and subacute complications of percutaneous coronary intervention (PCI), these procedures are generally only performed in centers where it is possible for failed PCI to be treated by rescue coronary artery bypass graft (CABG). Case reports and case series have documented successful PCI following failed CABG. We sought to confirm this decrease in the need for rescue CABG following failed PCI and to examine trends in the utilization of rescue PCI following failed CABG. HYPOTHESIS The interface between interventional cardiologist and cardiac surgeon is characterized by changing practice patterns and resource utilization. METHODS We examined the medical records of all patients admitted to the Brigham and Women's Hospital over a 7-year period and identified 169 patients who required both PCI and CABG during the same hospital admission. We describe and compare three predetermined groups of patients defined by the sequence of, and indication for, the relevant myocardial revascularization procedures. RESULTS In all, 100 patients required CABG for failed PCI, 46 patients had planned hybrid procedures involving both CABG and PCI, and 23 patients required PCI following failed CABG. There was a decrease in the need for rescue CABG following failed PCI, both in total numbers and as a percentage of total cases (2.5% in 1994 and 0.22% in 1999). There was a simultaneous increase in the utilization of rescue PCI following failed CABG (0% in 1994 and 1.6% in 2000). Hybrid procedures were identified as a source of innovative solutions to a variety of challenging clinical problems. CONCLUSIONS Changing patterns of resource utilization should be considered when planning hospital facilities and patient triage, and these patients undergoing percutaneous or surgical revascularization may benefit from close cooperation between the cardiac surgeon and the interventional cardiologist.

Abstract
Perioperative graft failure after coronary artery bypass graft (CABG) can result in acute myocardial infarction with dire clinical consequences. We report a case of rescue percutaneous coronary intervention immediately after unsuccessful CABG. This approach salvaged the patient from cardiogenic shock and should be recognized as a viable alternative to immediate reoperation for certain patients.

Abstract
A patient with a hypercoagulable state underwent coronary artery bypass grafting and was recovering uneventfully until diffuse electrocardiographic changes and cardiogenic shock developed within hours of the operation. Because of severe hemodynamic compromise on high-dose inotropic drugs and intraaortic balloon pump support, she was taken to the catheterization laboratory, where the patient was discovered to have thrombotic occlusion of all grafts, including the left internal mammary artery to the left anterior descending artery. Multiple graft percutaneous transluminal coronary angioplasty and thrombolysis with urokinase successfully opened the grafts, without bleeding complication. Anastomoses were all free of significant anatomic lesion. She has remained free of cardiac symptoms for 3.5 years after operation.

Abstract
Ischemic complications in the perioperative period following bypass surgery adversely affect both short- and long-term prognosis. Coronary angioplasty was successfully performed in 2 patients sustaining complicated postoperative myocardial infarctions with resolution of angina and restoration of hemodynamic stability. These cases illustrate that angioplasty can be done safely in such patients and may favorably alter short-term outcome.
