BACKGROUND: The use of rapid-deployment aortic valve replacement (RD-AVR) has burgeoned in recent years. There are few studies comparing RD-AVR to conventional aortic valve replacement (cAVR) and no studies where both were inserted via full sternotomy. As such, we reviewed our experience and compared the two approaches. METHODS: From 2008 to 2015, 597 patients underwent isolated aortic valve replacement ± coronary artery bypass grafting (CABG) at a single centre...

INTRODUCTION: Reperfusion injury is a well-known phenomenon following restoration of the coronary circulation after coronary artery bypass grafting (CABG) that impairs myocardial function. In order to control the severity of this injury, we aimed to investigate the effect of a new conditioning strategy namely ischemic postconditioning (IPOC) along with controlled aortic root reperfusion (CARR) on myocardial protection in CABG surgery with cardiopulmonary bypass. METHODS: In a doubled blind clinical trial study, 51 patients undergoing first-time elective CABG were randomly divided in three groups: CARR, IPOC, and combination of IPOC and CARR...

BACKGROUND: Outcomes following Coronary artery bypass grafting (GABG) vary between genders, with females having a higher postoperative mortality than males. Most of the studies are on Caucasian or mixed population and it is postulated that Asian population and in particular women have higher morbidity and mortality. In this study we have compared outcomes of elective CABG in men and women of South Asian origin in terms of morbidity and mortality. METHODS: From January 2006 to December 2012, 1970 patients underwent isolated elective CABG at the Aga Khan University Hospital, Pakistan were selected...

The use of arterial conduits is associated with incremental benefits when compared to conventional CABG surgery, albeit there is a paucity of data regarding the long-term outcomes of either techniques. Among 973 consecutive patients undergoing CABG, a propensity-match study was performed to compare total arterial revascularization technique (G1) with a conventional approach (LITA on LAD plus additional SVGs, G2). The study population was propensity-matched based on preoperative characteristics (age, sex, risk factors)...

OBJECTIVES: Remote ischemic conditioning (RIC) by repetitive blood pressure cuff inflation/deflation around a limb provides cardioprotection in patients undergoing coronary artery bypass grafting (CABG). Cardioprotection is confounded by risk factors, comorbidities and comedications. We aimed to identify confounders that possibly attenuate the protection provided by RIC. METHODS: In a retrospective analysis of our single-center, randomized, double-blind trial of patients undergoing elective CABG with/without RIC prior to ischemic cardioplegic arrest, we analyzed demographics, medications and intraoperative variables...

Deterioration of cerebral performance remains a major problem after cardiac surgery. Axillary artery cannulation can improve clinical outcome, but some experimental series show a malperfusion of the right hemisphere. The aim of our clinical study was to analyze the intraoperative investigation of cerebral oxygenation in two different arterial cannulation sites by use of near-infrared spectroscopic oximetry (NIRO). We compared retrospectively the cerebral saturation of 20 patients with aortic cannulation (group AoC) and 20 patients with right axillary artery cannulation (group AxC) during either valve, coronary artery bypass graft (CABG), combined procedures, or aortic surgery...

BACKGROUND: Revascularisation of the left anterior descending coronary artery (LAD) is the most important part of coronary artery bypass grafting (CABG) operations. We analysed the results of CABG in patients with embedded LADs compared to age and gender-matched controls. METHODS: Among 4,102 patients undergoing primary on-pump CABG from January, 1999, through April, 2014, 92 had embedded LADs. Direct dissection (n= 19) or retrograde probe technique (n= 73) was utilised to expose the LAD...

Advanced age is a known risk factor for morbidity and mortality after coronary artery bypass grafting (CABG). Minimized extracorporeal circulation (MECC) has been shown to reduce the negative effects associated with conventional extracorporeal circulation (CECC). This trial assesses the impact of MECC on the outcome of elderly patients undergoing CABG. Eight hundred and seventy-five patients (mean age 78.35 years) underwent isolated CABG using CECC (n=345) or MECC (n=530). The MECC group had a significantly shorter extracorporeal circulation time (ECCT), cross-clamp time and reperfusion time and lower transfusion needs...

BACKGROUND: Bilateral internal mammary arterial (BIMA) grafts have repeatedly demonstrated superior outcomes compared with single IMA (SIMA) after coronary artery bypass grafting (CABG). Despite known survival benefits with BIMA use, perceived perioperative challenges often preclude BIMA use. We hypothesized that the use of BIMA remains underutilized, even in low-risk patients. METHODS: A total of 43,823 primary, isolated CABG patients in a regional Society of Thoracic Surgeons Database were evaluated...
