PURPOSE: The purpose of this study was to present the controversial role of adjuvant radiotherapy to a 72-year-old male patient with Masaoka stage II thymoma and coronary artery bypass and to review the relevant literature. METHODS: The data were collected by relevant studies on PubMed and EMBASE. Articles up to March 2017 were included. RESULTS: Although the radiation-induced vascular injury to the internal thoracic artery and its suitability for grafting in a patient who is candidate for coronary artery bypass is documented, the possible catastrophic effect of adjuvant radiotherapy to existing grafts in a patient with prior bypass surgery has not been fully investigated...

OBJECTIVES: Postoperative atrial fibrillation (AF) following coronary artery bypass graft surgery (CABG) is significantly associated with reduced survival, but poor characterisation and inconsistent definitions present barriers to developing effective prophylaxis and management. We sought to address this knowledge gap. METHODS: From 2002 to 2010, 11 239 consecutive patients without AF underwent isolated CABG at five sites. Clinical data collected for the Society of Thoracic Surgeons (STS) Database were augmented with details on AF detected via continuous in-hospital ECG/telemetry monitoring to assess new-onset post-CABG AF (adjusted for STS risk of mortality); time to first AF; durations of first and longest AF episodes; total in-hospital time in AF; number of in-hospital AF episodes; operative mortality; stroke; discharge in AF; and length of stay (LOS)...

BACKGROUND: Low cardiac output syndrome is a main cause of death after cardiac surgery. We sought to assess the impact of glucose-insulin-potassium (GIK) to enhance myocardial protection in moderate- to high-risk patients undergoing on-pump heart surgery. METHODS: A randomized controlled trial was performed in adult patients (Bernstein-Parsonnet score >7) scheduled for elective aortic valve replacement and/or coronary artery bypass surgery. Patients were randomized to GIK (20 IU of insulin, 10 mEq of potassium chloride in 50 mL of glucose 40%) or saline infusion given over 60 minutes on anesthetic induction...

BACKGROUND: Estimation of cardiac output (CO) is essential in the treatment of circulatory unstable patients. CO measured by pulmonary artery catheter thermodilution is considered the gold standard but carries a small risk of severe complications. Stroke volume and CO can be measured by transesophageal echocardiography (TEE), which is widely used during cardiac surgery. We hypothesized that Doppler-derived CO by 3-dimensional (3D) TEE would agree well with CO measured with pulmonary artery catheter thermodilution as a reference method based on accurate measurements of the cross-sectional area of the left ventricular outflow tract...

Prior to the 1970s, pediatric coronary artery bypass surgery (PCABS) was seldomly performed due to the lack of compelling surgical indications. The advent of coronary sequelae secondary to Kawasaki disease (KD) and the occurrence of coronary artery complications due to newly developed procedures, such as the arterial switch operation and early repair for intrinsic congenital coronary malformations, necessitated the development of PCABS. Because children grow rapidly and their life expectancy is very long, with increasing exercise capability requirements, the strategy for PCABS should differ from that for bypass surgery in adults...

Background: Risk stratification is an important component of left main percutaneous catheter intervention (PCI) which has emerged as a feasible alternative to cardiac surgery. We sought to compare the clinical SYNTAX score and the global risk score in predicting outcomes of patients undergoing unprotected left main PCI in our institution. Methods: Clinical, angiographic and procedural characteristics of 92 patients who underwent unprotected left main PCI (mean age 62 ± 12...

BACKGROUND: The decision for coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in patients with multi-vessel coronary artery disease (mCAD) is currently made by a heart-team approach. Patients' preference is less well investigated. METHODS: All consecutive patients with prior CABG and at least 2 PCI procedures were interviewed whether they would elect bypass surgery or staged PCI in case of a hypothetical scenario in which they had mCAD and CABG or PCI will equally improve symptoms and survival...

BACKGROUND: Clinical outcomes in acute coronary syndrome patients treated with P2Y12 inhibitors who require urgent coronary artery bypass grafting (CABG) have not been well studied. METHODS: We examined clinical outcomes in acute coronary syndrome patients in relation to the timing of CABG following P2Y12 inhibitor discontinuation (<72 h, 72 h to five days, >5 days). The primary ischemic outcome was a composite of death, reinfarction, need for revascularization, or stroke...

Background: In octogenarian patients there is a potential for more tangible clinical benefits from off-pump coronary artery bypass (OPCAB) compared to conventional coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB) (COCAB). We aimed to investigate whether, compared to COCAB, OPCAB is associated with better operative outcomes in octogenarians by analyzing the Nationwide Inpatient Sample (NIS) databases 2003-2011. Methods: Of the 134,117 discharge records from 797 hospitals analyzed of patients aged ≥80 years undergoing first time isolated CABG from 2003 to 2011, 70...

BACKGROUND: Observational studies suggest a survival advantage with bilateral single internal thoracic artery (BITA) versus single internal thoracic artery grafting for coronary surgery, whereas this conclusion is not supported by randomized trials. We hypothesized that this inconsistency is attributed to unmeasured confounders intrinsic to observational studies. To test our hypothesis, we performed a meta-analysis of the observational literature comparing BITA and single internal thoracic artery, deriving incident rate ratio for mortality at end of follow-up and at 1 year...

For patients with prior coronary artery bypass graft surgery, reaching lesions in native coronary arteries distal to the anastomosis of bypass grafts can be challenging due to long distance between the graft ostium and the lesion and significant tortuosity that needs to be traversed. We describe one such lesion in a patient presenting with non-ST segment elevation myocardial infarction and cardiogenic shock. The lesion was successfully treated using a variety of strategies, including use of a short guide catheter, long guidewire, a guide catheter extension, long shaft balloons and stents, and short length stents...

Background -Cardiac rehabilitation is strongly recommended after myocardial infarction (MI), percutaneous coronary intervention (PCI), or coronary artery bypass surgery (CABG), but is historically underused. We sought to evaluate variation in cardiac rehabilitation participation across the United States. Methods -From administrative data from the Veterans Affairs (VA) healthcare system and a 5% Medicare sample, we used ICD-9 codes to identify patients hospitalized for MI, PCI, or CABG from 2007-2011. After excluding patients who died within 30 days of hospitalization, we calculated the percent of patients who participated in one or more outpatient visits for cardiac rehabilitation during the 12 months after hospitalization...

BACKGROUND: A deep sternal wound infection (DSWI) can become a severe complication after cardiac surgery, with in-hospital mortality rates reaching up to 35%. Staphylococci, particularly methicillin resistant Staphylococcus aureus (MRSA), play important roles in its etiology. CASE PRESENTATION: This case report presents a patient who underwent coronary artery bypass surgery, and suffered postoperatively from a DSWI caused by MRSA. The pathogen was susceptible to vancomycin and rifampicin in vitro; however, this therapy was clinically ineffective...
