Importance: Identifying high-performing surgical valve centers with the best surgical outcomes is challenging. Hospital surgical volume is a frequently used surrogate for outcomes. However, its ability to distinguish low-performing and high-performing hospitals remains unknown. Objective: To examine the association of hospital procedure volume with hospital performance for aortic and mitral valve (MV) surgical procedures. Design, Setting, and Participants: Within an all-payer nationally representative data set of inpatient hospitalizations, this study identified 682 unique hospitals performing surgical aortic valve replacement (SAVR) and MV replacement and repair with or without coronary artery bypass grafting (CABG) between 2007 and 2011...

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)...

BACKGROUND: Cardiac surgical units must balance trainee education with the duty to provide optimal patient care. This is particularly challenging with valvular surgery, given the lower volume and increased complexity of these procedures. The present meta-analysis was conducted to assess the impact of trainee operator status on clinical outcomes following valvular surgery. METHODS: Medline, Embase and CENTRAL databases were systematically searched for studies reporting clinical outcomes according to the training status of the primary operator (consultant or trainee)...

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...

OBJECTIVE: Postoperative delayed wound healing, surgical site infections (SSIs), and other wound complications are associated with increased morbidity and health-care costs. In cardiothoracic surgery, wound complications can have life-threatening consequences. In recent years, negative pressure wound therapy (NPWT) has been applied over closed surgical incisions to help reduce tension and protect from external contamination. We report our initial experiences using a closed incision negative pressure therapy (ciNPT) over clean, closed sternotomy incisions at an Irish tertiary referral centre...

BACKGROUND: Surgical ablation (SA) for atrial fibrillation (AF) effectively restores sinus rhythm. Incompletely defined risk has previously limited concomitant performance of SA during cardiac operations. The study goals were to define performance trends and risk-adjusted outcomes for contemporary SA. METHODS: From July 2011 to June 2014, 86,941 patients with AF, but without endocarditis, underwent primary nonemergent cardiac operations in The Society of Thoracic Surgeons (STS) database...

INTRODUCTION: A cell salvage device is used in cardiac surgery with the aim of reducing allogeneic blood transfusion. Suction of blood from the operating field used for the device is often accompanied by diathermy smoke. There is limited published research to know if this blood is then contaminated with clinically significant levels of harmful chemicals from this smoke. Postoperative cardiac surgery patients are already physiologically vulnerable, making the optimization of salvaged blood worth considering...

INTRODUCTION: Safety concerns have been one of the main reasons opposing a wider acceptance of minimal invasive extracorporeal circuits (MiECC). Following an extensive experience and a multitude of modifications, we have set out to employ a modular MiECC as a universal extracorporeal circuit. METHODS: A total of 129 cardiac surgical procedures were performed by a single surgeon in 2013. Excluding procedures done under circulatory arrest or with the potential need of such, the MiECC was utilized in almost 90% of surgeries...

INTRODUCTION: Epiaortic ultrasound scanning (EAS) extended the use of ultrasound to the intraoperative diagnosis of aortic pathology. Surgical palpation of the ascending aorta underestimates the presence and severity of atherosclerotic plaques. Epiaortic ultrasound scanning has been used as an adjunct to transesophageal echocardiography (TEE) or as a primary direct diagnostic tool for imaging the ascending aorta as well as the aortic arch, which gained prominence as part of a multipronged intraoperative strategy to reduce atherosclerotic emboli...

Anomalous aortic origin of coronary arteries is rare. We report 3 cases of surgical treatment for anomalous aortic origin of coronary arteries. Case 1 was a 38-year-old man who was saved by the use of an automated external defibrillator from cardiopulmonary arrest while exercising. The coronary angiogram showed the right coronary artery arising from the left coronary sinus of Valsalva and being located between the aorta and the pulmonary trunk. He underwent coronary artery bypass grafting (CABG) using the right internal thoracic artery with ligation of proximal part of right coronary artery to prevent sudden death...

Body mass is reported to influence myocardial performance. Recent studies have emphasised the importance of negative inotropic adipocyte-derived factors and their impact on cardiac contractile function. However, the underlying mechanisms remain unclear. We aimed to determine whether body mass impacts cardiac force development on the level of the contractile apparatus. We examined the influence of body mass index (BMI) (3 groups: group I >25, group II 25-30, group III >30) on the myocardial performance of skinned muscle fibres...

BACKGROUND: The operation of aortic valve replacement (AVR) after CABG is a technically challenging procedure in respect to dissection of living grafts from its surrounding tissue, myocardial protection, and so on, especially that procedure to patients with living in situ functional arterial grafts to occluded native coronary arteries has a special problem in regard to myocardial protection because myocardial blood supply originates from various arteries including the left internal thoracic artery (LITA), the right internal thoracic artery (RITA), and the right gastroepiploic artery (GEA); hence, adequate myocardial protection should be fastidiously considered...

For the year 2016, more than 20,000 published references can be found in Pubmed when entering the search term "cardiac surgery". Publications last year have helped to more clearly delineate the fields where classic surgery and modern interventional techniques overlap. The field of coronary bypass surgery (partially compared to percutaneous coronary intervention) was enriched by five large prospective randomized trials. The value of CABG for complex coronary disease was reconfirmed and for less complex main stem lesions, PCI was found potentially equal...

INTRODUCTION: Redo surgical aortic valve replacement after prior cardiac surgery is usually related to a higher risk of mortality and morbidity. Transcatheter aortic valve implantation (TAVI) became an alternative therapy for those patients in the past couple of years. EVIDENCE ACQUISITION: We aimed in this study to analyze the outcomes of patients undergoing TAVI after a prior cardiac surgery especially those who underwent coronary artery bypass grafting (CABG) and to see if TAVI offers any advantages for those patients than conventional surgical aortic valve replacement...

BACKGROUND: The association of anaemia with aortic stenosis (AS) has been recognised for over 50 years; however, although there have been several sporadic reports, there are few data on the prevalence of this syndrome. AIMS: We sought to compare the prevalence of anaemia in adults with AS with that of controls who had undergone coronary artery bypass grafting (CABG). METHODS: We conducted a retrospective cohort study comparing pre-procedural levels of haemoglobin in 1537 adults who underwent aortic valve replacement (AVR) for AS with 8025 contemporaneous patients who had CABG...

Situs inversus totalis and anomalous origin of the left coronary artery are rare conditions. An 87-year-old woman with both conditions presented to the authors' hospital with symptomatic aortic stenosis. She underwent aortic valve replacement (AVR) and coronary artery bypass grafting (CABG; saphenous vein graft to the left main trunk). The operator mainly stood on the left side of the patient and performed surgery without difficulty. Both, AVR and CABG were successfully performed despite these two rare conditions...
