The role of platelets in ischaemic events is well established. Aspirin represents the default antiplatelet and blocks the metabolism of arachidonic acid (AA) at the cyclo-oxygenase enzyme (COX). AA is commonly used as a test of response to aspirin, but recent data raise uncertainty about the validity of this approach. Specifically, in some patients AA-induced clotting is not suppressed, but the level of COX-dependent AA metabolite, thromboxane B2 (TXB2) is negligible. Furthermore, AA-induced whole blood clotting varies dynamically in individuals, who are aspirin responsive according to TXB2 levels...

BACKGROUND: Performance of tricuspid annuloplasty (TA) in patients undergoing mitral valve surgery is recommended based on the degree of tricuspid regurgitation and tricuspid annulus size, but is often underused. AIM: To evaluate the impact of combined TA on in-hospital outcome in patients undergoing mitral valve replacement (MVR). METHODS: We selected all consecutive patients who underwent MVR for native valve disease. Clinical, echocardiographic and in-hospital complications were obtained from chart review...

OBJECTIVE: To report the learning curve and early results of robotic mitral valve repairs in comparison with propensity score-matched sternotomy controls after the adoption of a robotic mitral valve surgery program in a university teaching hospital. METHODS: A total of 142 patients underwent robotic mitral valve repair due to degenerative mitral regurgitation between May 2011 and December 2015. Control patients operated on via the conventional sternotomy approach were selected by the use of propensity score analysis resulting in 2 well-matched study groups...

BACKGROUND: A modified technique for frozen elephant trunk (FET) repair of acute DeBakey type I dissection has evolved. Procedural modifications are described and midterm outcomes evaluated. METHODS: From 2009 to 2016, 72 patients with DeBakey type I dissection underwent emergency simplified FET. Mean age was 59 ± 15 years. Presentation included malperfusion (n = 22, 31%), rupture (n = 12, 16%), and aortic insufficiency (n = 42, 58%). Concomitant procedures included valve replacement (n = 9), root replacement (n = 11; valve sparing n = 6), cusp repair (n = 11), and valve resuspension (n = 21)...

OBJECTIVE: The disease of the aortic arch is traditionally approached by open surgical repair requiring cardiopulmonary bypass and circulatory arrest. This study performed a retrospective analysis comparing outcomes through primary hybrid patients submitted to aortic arch surgery without cardiopulmonary bypass with patients submitted to conventional open surgery. METHODS: 25 patients submitted to the aortic arch surgery were selected in the period 2003-2012 at the Madre Teresa Hospital in the city of Belo Horizonte, Brazil; 13 of these underwent hybrid technique without cardiopulmonary bypass and 12 underwent conventional open surgery...

BACKGROUND Improving quality and effectiveness of healthcare is one of the priorities of health policies. Hospital or physician volume represents a measurable variable with an impact on effectiveness of healthcare. An Italian law calls for the definition of «qualitative, structural, technological, and quantitative standards of hospital care». There is a need for an evaluation of the available scientific evidence in order to identify qualitative, structural, technological, and quantitative standards of hospital care, including the volume of care above or below which the public and private hospitals may be accredited (or not) to provide specific healthcare interventions...

The field of minimally invasive cardiac surgery has undergone rapid transformation over recent years. In this review, we provide a summary of the most current evidence supporting the use of minimally invasive aortic and mitral valve replacement techniques, as well as transcatheter approaches for aortic and mitral valve disease. As an adjunct, the use of robotically assisted coronary bypass surgery and hybrid coronary revascularization procedures is discussed. In order to obtain optimal patient outcomes, a collaborative, heart-team approach between cardiac surgeons and interventional cardiologists is necessary...

BACKGROUND: Studies on stroke risk following cardiac procedures addressed only perioperative and long-term risk following limited higher-risk procedures, were poorly generalizable, and often failed to stratify by stroke type. We calculated stroke risk in the intermediate risk period following cardiac procedures compared with common noncardiac surgeries and medical admissions. METHODS AND RESULTS: The Nationwide Readmissions Database contains readmission data for 49% of US admissions in 2013...

The aim of this analysis was to identify current trends in patient selection, procedural characteristics and outcomes after sAVR in Germany. METHODS: We analysed data from 42 776 patients included in the German Aortic Valve Registry who underwent sAVR with and without coronary artery bypass surgery (CABG) between 2011 and 2015...

OBJECTIVES: Although strict blood glucose control during cardiovascular surgery is essential to avoid postoperative complications, the various changes in glucose levels that occur during surgery have not been investigated in detail. In this study, we continuously monitored blood glucose changes during aortic surgery using the STG-55Ⓡ artificial endocrine pancreas (Nikkiso Inc., Tokyo). METHODS: Between December 2015 and 2016, we performed continuous blood glucose monitoring in 22 patients (14 men and 8 women, 72 ± 11 years old), who required hypothermic circulatory arrest during an ascending/aortic arch surgery, at the Jichi Medical University Hospital...

Introduction: Aortic valve replacement (AVR) with a mechanical prosthesis is not free from late complications. Aim: To evaluate the prevalence of subclinical hemolysis after AVR with On-X prostheses and assess its impact on long-term outcomes. Material and methods: The prospective study included 84 consecutive patients aged 58.3 ±10.3 years who underwent AVR. They were retrospectively split into group H (n = 12; 14.3%) with prosthesis-related subclinical hemolysis and a control group (C; n = 72; 85...

Aortic arch hypoplasia is commonly present in neonates born with ductal-dependant coarctation of the aorta. The ideal surgical repair of neonates with proximal arch hypoplasia continues to be debated. Controversy exists about the fate of the hypoplastic proximal aortic arch following surgical repair and whether that will eventually grow to normal size upon relief of the distal obstruction or will persist as a residual lesion that can affect long-term outlook of those patients. There is new evidence that residual proximal arch hypoplasia and the shape of the reconstructed arch both have an important impact on vascular remodelling and subsequent development of hypertension...

Background: Arterial stiffness, measured by pulse wave velocity (PWV), is linked to obesity, cardiovascular disease and all-cause mortality. Short-term weight loss improves PWV, but the long-term effects are unknown. We investigated the effect of pronounced long-term weight loss on PWV and whether anthropometric/metabolic parameters and/or white adipose tissue (WAT) phenotype could predict this change in PWV. Methods: Eighty-two obese subjects were examined before and two years after Roux-en-Y gastric bypass...
