Abstract
Challenging times are here for cardiac surgical and anesthesia team. The interventional cardiologist seem to have closed the flow of ‘good cases’ coming up for any of the surgery,; successful percutaneous interventions seem to be offering reasonable results in these patients, who therefore do not knock on the doors of the surgeons any more. It is a common experience among the cardiac anesthesiologists and surgeons that the type of the cases that come by now are high risk. That may be presence of comorbidities, ongoing medical therapies, unstable angina, uncontrolled heart failure and rhythm disturbances; and in patients with ischemic heart disease, the target coronaries are far from ideal. Several activities such as institution of preoperative supportive circulatory, ventilatory, and systemic disease control maneuvers seem to have helped improving the outcome of these ‘high risk ‘ patients. This review attempts to look at various interventions and the resulting improvement in outcomes. Several changes have happened in the realm of cardiac surgery and several more are en route. At times, for want of evidence, maximal optimization may not take place and the patient may encounter unfavorable outcomes.. This review is an attempt to bring the focus of the members of the cardiac surgical team on the value of preoperative optimization of risks to improve the outcome. The cardiac surgical patients may broadly be divided into adults undergoing coronary artery bypass graft surgery, valve surgery and pediatric patients undergoing repair/palliation of congenital heart ailments. Optimization of risks appear to be different in each genre of patients. This review also brings less often discussed issues such as anemia, nutritional issues and endocrine problems. The review is an attempt to data on ameliorating modifiable risk factors and altering non modifiable ones.

Abstract
Left main stem (LMS) disease is known to be a poor prognostic factor in terms of morbidity or mortality. Traditionally, it has been treated with constitution of bypass to provide required haemodynamic stability. We searched the literature for evidence on off-pump (OFP) surgery for treating this high-risk group of patients focusing in our review on postoperative outcomes, concerns and controversies. The majority of the studies identified showed favourable or equal outcomes of OFP when compared to conventional approach. All of the studies, apart from two, which showed lower incidence of postoperative deaths, demonstrated equal mortality rates. Stroke rates were found less in three studies. Less blood transfusions, inotropic use and length of study has been also demonstrated. The main concerns of OFP surgery are: haemodynamic instability and less complete revascularization. Main controversies are: same or favourable outcomes despite lower number of grafts with OFP surgery and less stroke rates despite manipulation of aorta with side-clamping. Despite these concerns and controversies OFP surgery has been proven to be feasible and safe as demonstrated by results from numerous studies.

Abstract
OBJECTIVE This study aimed to assess the long-term outcome of combined coronary revascularization. METHODS Between January 2000 and September 2010, 106 consecutive patients underwent combined coronary revascularization, either the same day or staged within 90 days. Percutaneous coronary intervention was always performed before coronary artery bypass grafting. We identified three groups as follows: one-stop combined coronary revascularization (n = 20), percutaneous coronary intervention for acute coronary syndrome before subsequent surgery (n = 39), and percutaneous coronary intervention for stable coronary artery disease before subsequent surgery (n = 47). Off-pump technique was used in all cases. RESULTS A total of 107 angioplasties were realized (drug-eluting stents, 21; bare metal stents, 114; balloon angioplasty, 4). Percutaneous coronary intervention was mostly performed in the right coronary artery or branches (85%). The mean (SD) number of grafts was 1.9 (0.6), among them 1.8 (0.7) with arterial grafts. A total of 87.7% of the patients underwent exclusive arterial revascularization. There was one reexploration for bleeding and no in-hospital death. Eleven patients died in the follow-up. Repeat percutaneous coronary intervention was necessary for six patients and repeat surgery for one patient. The mean (SD) follow-up was 6.1 (2.7) years. Complete follow-up was obtained in 96.2% of the patients. Freedom from ischemic events (all-cause deaths, angina, acute coronary syndrome, myocardial infarction) was 86.3% (3.7%) at 5 years and 79.7% (5.2%) at 8 years (no difference between groups). Freedom from major adverse cardiac or cerebrovascular events was 88.8% (3.4%) at 5 years and 75.7% (5.2%) at 8 years (no difference between groups). CONCLUSIONS Combined coronary revascularization increases the use of arterial grafts, with good long-term outcome.

Abstract
For several decades of medical history, coronary-artery bypass grafting (CABG) has been regarded as the best treatment option for patients with unprotected left main coronary artery (LMCA) disease, considering lesion priority and its clinical consequences. Over the time, with remarkable advancements in techniques of percutaneous coronary intervention (PCI), supporting devices, and adjunctive pharmacologic therapy, PCI with DES implantation has appeared to be new and alternative option for optimal revascularization therapy for these patients. The available cumulative evidence suggests that the safety outcomes such as mortality or composite of death, myocardial infarction and stroke are similar among PCI and CABG for patients with LMCA disease, the only difference was the rate of repeat revascularization. Current evidence and ongoing large clinical trials may encourage interventional cardiologists to choose PCI with stenting as an alternative revascularization strategy for unprotected LMCA disease in future. Finally, this evidence will change the current clinical practice and the guideline of optimal revascularization strategy for unprotected LMCA disease.

Abstract
OPINION STATEMENT Considering lesion priority and its clinical consequences, coronary artery bypass grafting (CABG) has been a treatment of choice for revascularization in patients with significant left main coronary artery (LMCA) disease, However, with remarkable advancements in techniques of percutaneous coronary intervention (PCI), supporting devices, and adjunctive pharmacologic therapy, PCI with stenting has emerged to be a less invasive and feasible revascularization treatment for these patients. The cumulative evidence suggests that the safety outcomes such as mortality or composite of death, myocardial infarction, and stroke are similar among PCI and CABG, with the only difference being the rate of repeat revascularization. Based on these data, the current guideline of revascularization of LMCA disease has adopted an increasing off-label experience with stenting and clinical studies and been updated to partly approve PCI as a viable alternative (in level of class IIb) in selected patients. The choice of PCI or CABG for unprotected LMCA disease depends on several clinical and anatomic features, ensuring crucial patient selection to be a cornerstone for achieving favorable long-term outcomes. In patients with very complex anatomic features and concomitant diffuse multivessel disease, CABG is preferred so as to avoid procedural and future thrombotic risks and to provide more complete revascularization. By contrast, in patients with relatively simple LMCA disease, such as ostial/shaft LMCA disease, isolated LMCA disease (with or without one or two-vessel involvement), and LMCA disease with low SYNTAX score, PCI is an alternative, and in some cases a preferred, strategy to reduce surgical risks (eg, stroke and in-hospital events following major surgery). For the future, ongoing large clinical trials might also boost interventional cardiologists to select PCI with stenting as an alternative revascularization strategy for unprotected LMCA disease. This evidence will most likely change the current clinical practice and guidelines of optimal revascularization strategy for unprotected LMCA disease.

Abstract
Recognition of the potentially deleterious effects of esxtracorporeal circulation led to off-pump coronary artery surgery (OPCAB) experiencing a surge in popularity in the initial decade after its conception. However, OPCAB has its own limitations and technical difficulties, such as coronary access, increased left ventricular size and reduced function, which may lead to the potential for suboptimal revascularization. As an alternative technique, miniaturized extracorporeal circulation (mECC) may provide a more controlled operative field in which the heart may be manipulated whilst minimizing the inflammatory, coagulopathic and haemodilutional effects of cardiopulmonary bypass. In this review, we outline the proposed benefits of the mECC system, discuss the pitfalls associated with mECC, and directly compare mECC to ‘off-pump’ coronary surgery for a variety of clinical and non-clinical outcomes.

J Thorac Cardiovasc Surg 2011; 143:103-10.

Abstract
BACKGROUND Our aim was to determine whether general left main coronary artery stenosis (LMS) and ostial LMS pose additional risks after off-pump coronary artery bypass grafting (CABG) relative to non-left main coronary artery stenosis. METHODS From January 1, 2008, to December 31, 2009, 4366 patients underwent primary isolated off-pump CABG at Beijing Anzhen Hospital. Disease was retrospectively classified as non-left main disease (n = 3523), nonostial LMS (n = 765), and ostial LMS (n = 78). Groups were propensity score matched. Kaplan-Meier freedoms from major adverse cardiac and cerebrovascular events (MACCEs) were calculated. RESULTS During the first 30 postoperative days, mortality was significantly higher in the ostial LMS group (6.41%) than in non-left main disease (0.855%, χ(2) = 7.78, P = .005) and nonostial LMS (1.28%, χ(2) = 4.71, P = .03) groups. Incidence of MACCEs was significantly higher in the ostial LMS group (20.5%) than in non-left main disease (5.98%, P = .000) and nonostial LMS (9.62%, P = .002) groups. Odds ratio for early MACCEs of ostial LMS versus non-left main disease was 3.74 (95% confidence interval, 1.72-8.17). At mean follow-up 12.8 ± 7.5 months and cumulative follow-up 498.5 patient-years, difference among groups in freedom from MACCEs did not reach statistical significance (χ(2) = 2.39, P = .303). CONCLUSIONS Ostial LMS poses additional early risks of mortality and MACCEs in off-pump CABG. Off-pump CABG for ostial LMS should proceed with greater of intraoperative surveillance and lower threshold for converting to on-pump CABG.

Abstract
It is considered that over 25% of surgical patients with coronary artery disease are treated without extracorporeal circulation, i.e. off-pump coronary artery bypass. The aim of the study was to evaluate results of surgical myocardium revascularization in patients at high operative risk. During the period 2005-2008, 148 patients were operated without the use of extracorporeal ciruculation. According to the logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) stratification, 28 patients (19%) were designated as the high risk patients. The average age of these high risk patients was 72 years (55-86). The group consisted of 23 men (82.1%) and 5 women (17.8%). The postoperative mortality in the whole group of patients was 0.68% (1/148), whereas it was 0% in the high risk group. The average number of coronary anastomoses was 2.4. Eight patients (28.6%) had some sort of postoperative complications. Our results demonstrate safety and efficacy of surgical revascularization without cardiopulmonary bypass in patients at high operative risk.

Abstract
PURPOSE OF REVIEW Octogenarians are the fastest growing stratum of the population and have the highest prevalence of coronary artery disease. In the past, physicians have been reluctant to provide these patients with optimal care. Seniors are frequently excluded from large randomized trials and generally not included in published guidelines. The purpose of this review is to revisit the demography and epidemiology of coronary artery disease in this population as well as therapeutic strategies used. RECENT FINDINGS Recent publications have shown significant advancement in medical and invasive treatment of coronary artery disease in elderly, with special focus on the potential benefit of off-pump coronary artery bypass (OPCAB) surgery. SUMMARY Although OPCAB surgery has gained popularity over the past 15 years, its benefit regarding operative mortality and major complications has not been clearly defined in the general population. There is a body of literature supporting its benefit in the elderly population. OPCAB surgery has the potential of decreasing operative mortality and major postoperative complications such as stroke, delirium, atrial fibrillation, and decline in neurocognitive functions in these patients. Off-pump surgery is technically more demanding and has been blamed for providing less complete revascularization and lower graft patency rate, especially in less experienced hands. However, with the upcoming demographic explosion of senior citizens in western societies, OPCAB surgery has definitely to be a part of the armamentarium of modern cardiac surgeons.
