Background/aim: Myocardial protection is an important factor of open heart surgery and biological biomarkers (lactate, CKMB, cardiac troponin I, and pyruvate) are used to assess myocardial damage. This study compares the effects of dexmedetomidine and remifentanil on myocardial protection during coronary artery bypass grafting (CABG) surgery. Materials and methods: Patients scheduled for elective CABG surgery (n = 60) were included in this study. Anesthesia induction was introduced with propofol, fentanyl, and vecuronium bromide...

OBJECTIVE: Del Nido cardioplegia (DC) offers prolonged cardiac protection with single dose administration and has been shown to be safe in adult CABG surgery. We set out to evaluate the efficacy of cardiac protection and clinical outcomes of del Nido cardioplegia versus standard blood cardioplegia (BC) in minimally invasive aortic valve surgery. METHODS: From 8/2011 to 5/2016, 178 patients underwent minimally invasive aortic valve replacement (AVR) with BC (n=101) or DC (n= 77)...

OBJECTIVE: del Nido solution (DNS) is a single-dose cardioplegia designed for pediatric use proposed to offer superior myocardial protection in adults. However, few data support this claim. We hypothesized that DNS and modified blood cardioplegia solution (BS) provide equivalent safety in combined adult valve surgery. METHODS: Between November 2014 and December 2015, 25 patients underwent primary aortic valve replacement and concomitant coronary artery bypass grafting (CABG) with DNS...

Background: Fast-track cardiac surgery programs have been established as the standard of cardiac surgical care. Studies have shown that early extubation in elective cardiac surgery patients, including coronary and non-coronary open-heart surgery patients does not increase perioperative morbidity and mortality. The objective of this observational study was to determine the success and failure profile of fast track extubation (FTE) practice in adult open-heart surgical patients. Methods: The study was conducted at cardiac operating room and Cardiac Intensive Care Unit (CICU) of a tertiary care hospital for a period of nine months, i...

OBJECTIVE: Robotic coronary artery bypass grafting (CABG) was shown to be a safe and feasible method for the treatment of coronary artery disease in highly selected patients. However, long-term outcome data comparing robotic CABG with conventional CABG are still missing. Therefore, we aimed to compare robotic with conventional CABG in terms of perioperative and long-term outcomes. METHODS: Of 2947 consecutive elective patients with coronary artery disease operated at a single center between 2001 and 2013, 280 underwent robotic CABG...

BACKGROUND: In patients with prior cardiac surgery requiring re-operative coronary and valve surgery, a hybrid approach of percutaneous coronary intervention followed by minimally invasive valve surgery (PCI + MIVS) may be an alternative to the standard median sternotomy coronary artery bypass and valve surgery (CABG + valve). METHODS: The outcomes of patients with prior cardiac surgery, presenting with coronary artery and valvular disease, who underwent PCI + MIVS (N=39) were retrospectively compared with those who underwent CABG + valve (N=28) via a repeat median sternotomy, between February 2009 and April 2014...

BACKGROUND: The optimal treatment for concomitant two-vessel coronary artery disease (CAD) and moderate to severe ischemic mitral regurgitation (IMR) remains unclear. We compared the results of a staged percutaneous coronary intervention followed by minimally invasive mitral valve surgery (PCI+MIVS) versus combined coronary artery bypass graft and mitral valve surgery (CABG+MVS) in this population. METHODS: All consecutive patients with two-vessel CAD and moderate to severe IMR, who underwent PCI+MIVS or CABG+MVS at our institution between February 2009 and April 2014, were retrospectively evaluated...

OBJECTIVE: Coronary artery bypass grafting (CABG) remains the gold standard for complex revascularisation in multivessel disease. The concept of the minimally invasive extracorporeal circulation circuit (MiECC) was introduced to minimise pathophysiological side effects of conventional extracorporeal circulation. This study presents early and long-term outcomes after CABG with use of MiECC in a single-centre consecutive patient cohort. METHODS: From 1 January 2005 to 31 December 2010, 2130 patients underwent isolated CABG with MiECC at our centre...

BACKGROUND: Less-than-optimal long-term patency of the saphenous vein is one of the main obstacles for the success of coronary artery bypass grafting (CABG). Results from the IMPROVE-CABG trial has shown that harvesting the saphenous vein with a pedicle of perivascular tissue less than 5 mm while using manual distention provides comparable occlusion rates but significantly less intimal hyperplasia at early follow-up. The impact of pedicled veins on duration of operations, leg wound infections, and postoperative bleeding is unknown...

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...
