BACKGROUND: The use of radial-artery grafts for coronary-artery bypass grafting (CABG) may result in better postoperative outcomes than the use of saphenous-vein grafts. However, randomized, controlled trials comparing radial-artery grafts and saphenous-vein grafts have been individually underpowered to detect differences in clinical outcomes. We performed a patient-level combined analysis of randomized, controlled trials to compare radial-artery grafts and saphenous-vein grafts for CABG...

Driven by limited resources and a sense of urgency, the prioritization of species for conservation has been a persistent concern in conservation science. Gymnosperms (comprising ginkgo, conifers, cycads, and gnetophytes) are one of the most threatened groups of living organisms, with 40% of the species at high risk of extinction, about twice as many as the most recent estimates for all plants (i.e. 21.4%). This high proportion of species facing extinction highlights the urgent action required to secure their future through an objective prioritization approach...

Introduction: 'Porcelain aorta' is listed in the second consensus document of the Valve Academic Research Consortium as a risk factor in aortic valve replacement. However, the extent of circumferential involvement is poorly defined with great variability in reported incidence. We present a simple, reproducible classification to describe the extent of aortic calcification and thus appropriately define 'porcelain aorta', aiding clinical decision-making and registry data collection. Methods: 175 consecutive CT aortograms were reviewed...

Bioprostheses are prone to structural valve degeneration, resulting in limited long-term durability. A significant challenge when comparing the durability of different types of bioprostheses is the lack of a standardized terminology for the definition of a degenerated valve. This issue becomes especially important when we try to compare the degeneration rate of surgically inserted and transcatheter bioprosthetic valves. This document, by the VIVID (Valve-in-Valve International Data), proposes practical and standardized definitions of valve degeneration and provides recommendations for the timing of clinical and imaging follow-up assessments accordingly...

OBJECTIVES: The aim of this study was to determine whether the association of small label size of the surgical valve with increased mortality after transcatheter valve-in-valve (ViV) implantation is, at least in part, related to pre-existing prosthesis-patient mismatch (PPM) (i.e., a bioprosthesis that is too small in relation to body size). BACKGROUND: Transcatheter ViV implantation is an alternative for the treatment of patients with degenerated bioprostheses...

OBJECTIVE: Existing clinical prediction models (CPM) for short-term mortality after transcatheter aortic valve implantation (TAVI) have limited applicability in the UK due to moderate predictive performance and inconsistent recording practices across registries. The aim of this study was to derive a UK-TAVI CPM to predict 30-day mortality risk for benchmarking purposes. METHODS: A two-step modelling strategy was undertaken: first, data from the UK-TAVI Registry between 2009 and 2014 were used to develop a multivariable logistic regression CPM using backwards stepwise regression...

The tricuspid valve is a complex dynamic apparatus made up of many different closely linked structures: the annulus, the three leaflets, the chordae, the papillary muscles and the right ventricle. Other nearby structures, such as the coronary sinus ostium, the conduction system, the membranous septum, and the right coronary artery must be taken into account when dealing with the tricuspid. Annulus dilation and leaflet tethering due to right ventricular remodeling are the 2 major mechanisms responsible for most tricuspid regurgitation cases...

BACKGROUND: Conventional mitral valve (MV) operations allow direct anatomic assessment and repair on an arrested heart, but require cardiopulmonary bypass, aortic cross-clamping, sternotomy or thoracotomy, and cardioplegic cardiac arrest, and are associated with significant perioperative disability, and risks of morbidity and mortality. OBJECTIVES: This study evaluated safety and performance of a transesophageal echocardiographic-guided device designed to implant artificial expanded polytetrafluoroethylene (ePTFE) cords on mitral leaflets in the beating heart...

BACKGROUND: Transcatheter aortic valve implantation (TAVI) is indicated for patients with aortic stenosis who are intermediate-high surgical risk. Although all-cause mortality rates after TAVI are established, survival attributable to the procedure is unclear because of competing causes of mortality. The aim was to report relative survival (RS) after TAVI, which accounts for background mortality risks in a matched general population. METHODS AND RESULTS: National cohort data (n=6420) from the 2007 to 2014 UK TAVI registry were matched by age, sex, and year to mortality rates for England and Wales (population, 57...

Posttraumatic tricuspid valve regurgitation (TR) is a rare entity and is almost always associated with blunt chest trauma. It is usually identified by transthoracic echocardiography after the manifestation of clinical symptoms of heart failure. Treatment varies from long-term medical therapy and observation to surgical correction with tricuspid valve replacement or repair. We describe the case of a 26-year-old man who was involved in a major road traffic accident and was referred for surgical repair a year later because of severe posttraumatic TR...

AIMS: Transcatheter mitral valve replacement (TMVR) is a novel technique for treating mitral regurgitation. We report 18-month/two-year outcomes of the five first-in-man patients undergoing chronic TMVR with the Tendyne device. METHODS AND RESULTS: Five patients (STS score range 14%-23%) underwent TMVR using the Tendyne system under compassionate use at a single centre. One patient (who was non-compliant with anticoagulation) died nine months after TMVR following a cerebrovascular accident...

OBJECTIVES: This study sought to determine the risk factors for post-transcatheter aortic valve replacement (TAVR) dialysis and to determine the impact of pre-TAVR or post-TAVR dialysis on mortality. BACKGROUND: TAVR is now established as an alternative treatment to surgical aortic valve replacement. Data examining the impact of dialysis on outcomes after TAVR are lacking. METHODS: The UK TAVI (Transcatheter Aortic Valve Implantation) Registry was established to report outcomes on all TAVR procedures performed within the United Kingdom (2007 to 2014)...

The tricuspid valve was virtually ignored for a long time in the past. However, significant tricuspid regurgitation (TR) often accompanies left-side heart valve pathology and does not always reverse with its correction. If left untreated, TR can progress and result in progressive right ventricular failure. Current guideline recommendations still hold minor differences. Nevertheless, there is a consensus to operate on patients with severe TR undergoing left-sided valve surgery (class I) or those with mild to moderate TR with a dilated annulus (≥40 or ≥21 mm2 , Class IIa)...

BACKGROUND: Tricuspid valve (TV) repair at the time of left-sided valve surgery is indicated in patients with either severe functional tricuspid regurgitation (TR) or mild-to-moderate TR with coexistent tricuspid annular dilation or right heart failure. We assessed the benefits of a concomitant TV repair strategy during left-sided surgical valve interventions, focusing on mortality and echocardiographic TR-related outcomes. METHODS: A meta-analysis was performed of studies reporting outcomes of patients who underwent left-sided (mitral and/or aortic) valve surgery with or without concomitant TV repair...

BACKGROUND: Aortic stenosis (AS) poses a perioperative management dilemma to physicians looking after patients who require non-cardiac surgery. The objective of this review is to investigate mortality and adverse cardiovascular events in patients with and without AS who underwent non-cardiac surgery. METHODS: We searched MEDLINE and EMBASE for studies that evaluated mortality and adverse cardiovascular events in patients with and without AS who underwent non-cardiac surgery...
