Aortic stenosis guidelines

Hui Li, Miguel Castro, Pascal Haigron, Jean-Philippe Verhoye, Vito Giovanni Ruggieri
PURPOSE: Minimally invasive aortic valve replacement (MIAVR) procedures remain more complex and technically challenging compared to conventional full sternotomy surgery. This technique involves a restricted surgical field and a limited workspace, which is, at present, strictly reserved for the most experienced surgeons. The MIAVR clinical outcomes are strongly dependent on the appropriate choice of the thoracic incision. This work presents a decision support system to optimize, through an interactive visualization interface, the exposure of the target structure in a limited field of view...

OBJECTIVES: The Ross procedure has demonstrated excellent results when performed in patients with aortic stenosis or mixed aortic valve disease [aortic stenosis and aortic regurgitation (AR)]. However, due to its reported risk of late reoperation, it is not recommended under current guidelines for patients presenting with bicuspid aortic valve and pure AR. We have analysed our own results in light of this recommendation. METHODS: Between 1993 and 2016, 129 consecutive patients with a mean age of 34...

We herein report anesthetic management during aortic valve replacement for aortic valve regurgitation in a patient with adult mucopolysaccharidosis type II (MPS type 2) (Hunter syndrome). This disorder is rare and related to the accumulation of a mucopolysaccharide in lysosomes. It affects various organs, including the airways, heart, and central nerves. In children with MPS type 2, the risk of airway obstruction during anesthesia/sedation is high, and the degree of difficulty increases with aging. The patient described herein was a 33-year-old male without mental retardation...

OBJECTIVES: This study sought to determine the impact of left ventricular (LV) diastolic dysfunction (LVDD) on clinical outcomes in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND: LV hypertrophy in response to afterload increase promotes the development of LVDD and represents an early stage in the progression to valvular heart failure. METHODS: In a consecutive cohort of 777 aortic stenosis patients undergoing TAVR, LVDD was categorized according to the latest guidelines...

BACKGROUND: Disease progression of an isolated bicuspid aortic valve (BAV) in children is poorly understood and adult management guidelines may not be applicable. Thus, we sought to evaluate disease progression of pediatric isolated BAV and its relationship to current management practices. METHODS: Children with a BAV and ≤mild aortic stenosis (AS) and/or aortic regurgitation (AR) at the time of initial evaluation were included in this retrospective cohort study (1/2005-12/2014)...

INTRODUCTION: Traditional and transcatheter surgical treatments of severe aortic valve stenosis (SAVS) are increasing in parallel with the improved life expectancy. Recent randomised controlled trials (RCTs) reported comparable or non-inferior mortality with transcatheter treatments compared with traditional surgery. However, RCTs have the limitation of being a mirror of the predefined inclusion/exclusion criteria, without reflecting the 'real clinical world'. Technological improvements have recently allowed the development of minimally invasive surgical accesses and the use of sutureless valves, but their impact on the clinical scenario is difficult to assess because of the monocentric design of published studies and limited sample size...

BACKGROUND: In the American College of Cardiology/American Heart Association guidelines, patients are considered to have true-severe stenosis when the mean gradient (MG) is ≥40 mm Hg with an aortic valve area (AVA) ≤1 cm2 during dobutamine stress echocardiography (DSE). However, these criteria have not been previously validated. OBJECTIVES: The aim of this study was to assess the value of these criteria to predict the presence of true-severe AS and the occurrence of death in patients with low-flow, low-gradient aortic stenosis (LF-LG AS)...

BACKGROUND: The ACC/AHA guidelines recommend low-dose dobutamine challenge for hemodynamic assessment of the severity of AS in patients with low flow, low gradient aortic stenosis with reduced ejection fraction (EF) (LFLG-AS; stage D2). Inherent pitfalls of echocardiography could result in inaccurate aortic valve areas (AVA), which have downstream prognostic implications. Data on the safety and efficacy of coronary pressure wire and fluid-filled catheter use for low dose dobutamine infusion is sparse...

Transcatheter heart valve replacement technology was introduced as alternative to surgery for the growing high-risk profile population. Developed first, aortic valve replacement (TAVR) became a standard of care for patients with severe aortic stenosis at high operative risk, with a potential future use also for low-risk subjects. In the last decade, a multitude of transcatheter mitral valve replacement (TMVR) devices have been developed for the treatment of severe mitral regurgitation, with encouraging results coming from first-in-man and feasibility studies...

Importance: Clinical practice guidelines currently endorse a reliance on clinical symptoms of overt left ventricular (LV) failure to time aortic valve replacement for severe aortic stenosis; however, delayed aortic valve replacement can result in irreversible LV injury and adverse outcomes. Blood metabolomic signatures possess prognostic value in heart failure; this study assesses whether they are informative in aortic stenosis. Objective: To evaluate the value of metabolomic signatures in reflecting the extent of maladaptive LV remodeling in patients with end-stage aortic stenosis undergoing transcatheter aortic valve replacement, and to assess whether this procedure reverses metabolomic aberrations...

PURPOSE: Transcatheter aortic valve replacement (TAVR) is an increasingly prevalent therapy in patients with severe symptomatic aortic stenosis. Conduction disturbances requiring permanent pacemaker (PPM) implantation are a known complication of TAVR. This study investigated the progression of cardiac conduction disease in the post-TAVR pacemaker population and identified predictors of post-TAVR right ventricular (RV) pacing dependence. METHODS: Prospectively collected echocardiographic, ECG, and PPM interrogation data of 262 consecutive patients who underwent TAVR with placement of a balloon-expandable valve at one institution from March 2012 to October 2016 were analyzed...

PURPOSE OF REVIEW: There is a growing emphasis on the conduct of large-scale, multicenter randomized controlled trials (RCTs) to guide decision-making in cardiac surgery. Here we review recent landmark RCTs in cardiac valvular surgery. RECENT FINDINGS: RCTs are the gold-standard level of data in medicine. However, there are unique challenges of conducting large-scale surgical trials including funding, blinding, generalizability, nonstandardization of the surgical technique, crossover, among others...

After 5 years the European Society of Cardiology and the European Association for Cardio-Thoracic Surgery have released an update on the guidelines for the management of valvular heart diseases. In recent years published results of randomized trials in patients with aortic valve stenosis have resulted in updated recommendations for catheter-based prosthesis implantation (TAVI), which is now extended to patients presenting without a low risk for conventional surgical valve replacement. In mitral or tricuspid valvular disease, the recommendations for catheter-based therapies are less strong because of a lack of supportive scientific data...

INTRODUCTION: Aortic stenosis is the most prevalent type of valvular disease in Europe. Surgical aortic valve replacement (SAVR) is the standard therapy, while transcatheter aortic valve implantation (TAVI) is an alternative in patients at unacceptably high surgical risk. Assessment by a heart team is recommended by the guidelines but there is little published evidence on this subject. The purpose of this paper is to describe the experience of a multidisciplinary TAVI program that began in 2008...

This article gives an update on the management of acute ST-segment elevation myocardial infarction (STEMI) according to the recently released European Society of Cardiology guidelines 2017 and the modifications are compared to the previous STEMI guidelines from 2012. Primary percutaneous coronary intervention (PCI) remains the preferred reperfusion strategy. New guideline recommendations relate to the access site with a clear preference for the radial artery, use of drug-eluting stents over bare metal stents, complete revascularization during the index hospitalization, and avoidance of routine thrombus aspiration...

OBJECTIVE/BACKGROUND: Endovascular aneurysm repair (EVAR) may be associated with renal injury and more insight is needed into potential risk factors. The aim was to identify clinical, anatomical, and peri-procedural parameters as potential risk factors for the occurrence of acute kidney injury (AKI) and to evaluate chronic kidney disease (CKD) after EVAR. METHODS: A cohort of 212 consecutive patients who underwent elective EVAR for abdominal aortic aneurysm from January 2009 to October 2016 was included...

Aims: Pulmonary hypertension (PH) is common in severe symptomatic left-sided valvular disease, particularly in aging populations. Inconsistent results have been reported concerning the association between PH and adverse outcomes after aortic valve replacement for aortic stenosis (AS). We therefore retrospectively investigated the prognostic significance of PH using peak tricuspid regurgitation velocity (TRV), as defined by the current European Society of Cardiology (ESC)/European Respiratory Society (ERS) guidelines, in a large cohort of patients with severe AS...

Aortic stenosis is a common valvular condition with increasing prevalence in aging populations. When severe and symptomatic, the downstream prognosis is poor without surgical or transcatheter aortic valve replacement. Transcatheter aortic valve replacement is now considered a viable alternative to surgical aortic valve replacement in patients considered high and intermediate risk for surgery. Pre-intervention imaging with echocardiography and CT are essential for procedure planning and device selection to help optimize clinical outcomes with MR angiography playing largely a complementary role...

Transcather aortic valve implantation (TAVI) has become a safe and indispensable treatment option for patients with severe symptomatic aortic stenosis (AS) who are at high or prohibitive surgical risk. In the past years, outcomes after TAVI have improved significantly and TAVI has emerged as a qualified alternative to surgical aortic valve replacement (SAVR) in the treatment of intermediate risk patients. Besides optimized patient screening, advanced imaging and increased examiner experience, transcatheter heart valve (THV) design addressed several key issues like vascular complications, pacemaker implantation and paravalvular leakage rates and improved considerably over time...
