Transcatheter aortic valve implantation using the SAPIEN 3 valve to treat aortic regurgitation: The French multicentre S3AR study.

Background: Transcatheter aortic valve implantation now has a major role in the treatment of patients with severe aortic stenosis. However, evidence is scarce on its feasibility and safety to treat patients with pure aortic regurgitation.

Aims: We sought to evaluate the results of transcatheter aortic valve implantation using the balloon-expandable SAPIEN 3 transcatheter heart valve (Edwards Lifesciences, Irvine, CA, USA) in patients with pure aortic regurgitation on native non-calcified valves.

Randomized controlled trial between conventional versus sutureless bioprostheses for aortic valve replacement: Impact of mini and full sternotomy access at 1-year follow-up.

Background: The present study is a sub-analysis of the multicenter, randomized PERSIST-AVR trial (PERceval Sutureless Implant versus Standard Aortic Valve Replacement) comparing the in-hospital and 1-year results of sutureless versus conventional stented bioprostheses in isolated surgical aortic valve replacement (SAVR) within two different surgical approaches: mini-sternotomy (MS) and full-sternotomy (FS).

Methods: A total of 819 patients (per-protocol population) underwent preoperative randomization to sutureless or stented biological valve at 47 centers worldwide. Sub-analysis on isolated SAVR was performed.

Preservation of the Aortic Root During Type A Aortic Dissection Surgery: An Effective Strategy?

Background:  Management of the aortic root during acute Type A aortic dissection (TAAD) repair remains controversial in term of long-term evolution and reoperation. The aim of this study was to assess the long-term outcomes of the aortic root after conservative management during primary surgery.

Methods:  One hundred sixty-four consecutive patients were included in this monocentric retrospective study.

Prognostic value of a comprehensive geriatric assessment for predicting one-year mortality in presumably frail patients with symptomatic aortic stenosis.

Introduction: Despite suffering a severe aortic stenosis, some patients are denied either surgical or transcatheter aortic valve implantation (TAVI) therapy because of a frail condition. We aimed to identify whether a comprehensive geriatric assessment (CGA) might be useful to predict the prognosis of presumably frail patients with severe aortic stenosis.

Material And Methods: Between March 2011 and July 2016, 818 patients were consecutively and prospectively enrolled.

Cardiopulmonary bypass and internal thoracic artery: Can roller or centrifugal pumps change vascular reactivity of the graft? The IPITA study: A randomized controlled clinical trial.

Background: Cardiopulmonary bypass (CPB) induces a systemic inflammatory response (SIRS) and affects the organ vascular bed. Experimentally, the lack of pulsatility alters myogenic tone of resistance arteries and increases the parietal inflammatory response. The purpose of this study was to compare the vascular reactivity of the internal thoracic arteries (ITAs) due to the inflammatory response between patients undergoing coronary artery bypass grafting (CABG) under CPB with a roller pump or with a centrifugal pump.

Balloon-Expandable Versus Self-Expanding Transcatheter Aortic Valve Replacement: A Propensity-Matched Comparison From the FRANCE-TAVI Registry.

Background: No randomized study powered to compare balloon expandable (BE) with self expanding (SE) transcatheter heart valves (THVs) on individual end points after transcatheter aortic valve replacement has been conducted to date.

Methods: From January 2013 to December 2015, the FRANCE-TAVI nationwide registry (Registry of Aortic Valve Bioprostheses Established by Catheter) included 12 141 patients undergoing BE-THV (Edwards, n=8038) or SE-THV (Medtronic, n=4103) for treatment of native aortic stenosis. Long term mortality status was available in all patients (median 20 months; interquartile range, 14 to 30).

Outcomes of transcatheter aortic valve replacement without predilation of the aortic valve: Insights from 1544 patients included in the SOURCE 3 registry.

Aims: To investigate the impact of transcatheter aortic valve replacement (TAVR) without preliminary balloon aortic valvuloplasty (pre-BAV) on periprocedural outcomes in a large, real-world registry.

Methods And Results: The SOURCE 3 registry was an observational, multi-center, single-arm study of patients with severe, symptomatic aortic stenosis at high surgical risk treated with the SAPIEN 3 transcatheter heart valve (THV). Procedural and 30-day outcomes were compared between two groups of 772 patients each (retrospectively matched) with or without pre-BAV.

Transcarotid Approach for Transcatheter Aortic Valve Replacement With the Sapien 3 Prosthesis: A Multicenter French Registry.

Objectives: This study sought to describe the procedural and clinical outcomes of patients undergoing transcarotid (TC) transcatheter aortic valve replacement (TAVR) with the Edwards Sapien 3 device.

Background: The TC approach for TAVR holds the potential to become the optimal alternative to the transfemoral gold standard. Limited data exist regarding safety and efficacy of TC-TAVR using the Edwards Sapien 3 device.

One-Year Outcomes of a European Transcatheter Aortic Valve Implantation Cohort According to Surgical Risk.

Background: Transcatheter aortic valve implantation is increasingly being used in patients at lower risk for surgery. We aimed to assess the distribution of surgical risk score categories in current clinical practice and their relationship with clinical outcomes and the calibration and discrimination power of both the logistic EuroSCORE (logES) and EuroSCORE II. The SOURCE 3 study is a European prospective registry of patients with severe aortic stenosis treated with the commercially available SAPIEN 3 transcatheter heart valve.

Background: Transcatheter aortic valve replacement (TAVR) is standard therapy for patients with severe aortic stenosis who are at high surgical risk. However, national data regarding procedural characteristics and clinical outcomes over time are limited.

Objectives: The aim of this study was to assess nationwide performance trends and clinical outcomes of TAVR during a 6-year period.

Influence of stentless versus stented valves on ventricular remodeling assessed at 6 months by magnetic resonance imaging and long-term follow-up.

Background: To compare the effect of stented versus stentless bioprostheses on left ventricular remodeling and assess their impact on long-term survival.

Methods: From January 2002 to December 2009, 62 severe aortic stenosis patients without coronary artery disease were randomized for bioprosthetic aortic valve replacement. After randomization, a cross-over was possible based on intraoperative data.

Remote ischemic preconditioning in aortic valve surgery: Results of a randomized controlled study.

Background: Although remote ischemic preconditioning (RIPC) has emerged as an attractive strategy to reduce cardiac injury in patients undergoing diverse cardiac surgical procedures, it is unclear whether RIPC has protective effects in patients undergoing aortic valve replacement surgery without coronary artery bypass grafting (CABG).

Methods: Hence, 100 adult patients undergoing elective aortic valve replacement for aortic valve stenosis, without combined surgery with CABG, were prospectively randomly assigned in a 1:1 ratio to either the RIPC group or the control group. The RIPC group underwent three cycles of 5-min inflation to 200mmHg and 5-min deflation of an automated upper-arm cuff inflator after induction of anesthesia.

Endovascular treatment of iatrogenic aortic graft injury after sternal puncture.

We report the case of a 71-year old woman who had previously undergone supra-aortic trunk transposition via a median sternotomy, along with endovascular thoracic aortic stent-graft repair. During the diagnostic sternal puncture for a recently discovered acute lymphoblastic leukaemia, an accidental graft injury occurred. For this patient, who was not a surgical candidate, endovascular treatment with a covered stent (endograft) was performed, with uneventful postoperative follow-up.

Safety and efficacy of biocompatible perfusion strategy in a contemporary series of patients undergoing coronary artery bypass grafting - a two-center study.

Objective: The profile of patients referred for coronary artery bypass grafting (CABG) is continuously changing to include older patients with multiple comorbidities. We assessed the safety and efficacy of a biocompatible perfusion strategy (BPS) in a contemporary series of patients undergoing isolated CABG.

Methods: BPS consisted of a membrane oxygenator, tip-to-tip closed-system heparin-bonded cardiopulmonary bypass circuits without a cardiotomy reservoir, low systemic anticoagulation (target ACT - 250-300 sec) using heparin titration curves, low prime volume, avoidance of systemic cooling, and routine use of cell saver and anti-fibrinolytics.

Do patients with haematological malignancy who need cardiopulmonary bypass have a short-term higher mortality or a higher chance of disease progression?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether patients with haematological malignancy (HM) who need cardiopulmonary bypass (CPB) have a higher short-term mortality or a higher chance of disease progression secondary to CPB. Altogether, 107 papers were found using the reported search terms, but ultimately only eight were relevant to our subject.

CMR assessment after a transapical-transcatheter aortic valve implantation.

Aims: To describe the time course of myocardial scarring after transapical-transcatheter aortic valve implantation (TA-TAVI) with the Edwards SAPIEN XT™ and the Edwards SAPIEN™ prosthesis in a 3-month follow-up study using cardiac magnetic resonance imaging (CMR).

Methods: In 20 TA-TAVI patients, CMR was performed at discharge and 3 months (3M). Cine-MRI was used for left ventricular (LV) functional assessment, and late gadolinium enhancement (LGE) imaging was employed for detecting the presence of myocardial scarring.
