Idarucizumab (Praxbind) for dabigatran reversal in patients undergoing heart transplantation: a cohort of ten patients.

Background: Novel oral anticoagulants are used in atrial fibrillation. Idarucizumab has been approved for reversal of dabigatran in situations of life-threatening hemorrhage or emergency surgery.

Objectives: We report a single center experience of ten patients on dabigatran therapy who were given idarucizumab prior to heart transplantation.

Transcatheter aortic valve replacement performed with selective telemetry monitoring: A prospective study.

Background: Telemetry monitoring (TM) with or without intensive care unit (ICU) admission is the standard of care after Transcatheter aortic valve replacement (TAVR). Regarding to improvements of the technique and procedural results, TM may be considered only in selected patients. We aimed to confirm feasibility and safety of selective TM in patients undergoing TAVR.

Myocardial Injury After Balloon Predilatation Versus Direct Transcatheter Aortic Valve Replacement: Insights From the DIRECTAVI Trial.

Background Myocardial injury is associated with higher mortality after transcatheter aortic valve replacement (TAVR) and might be increased by prior balloon aortic valvuloplasty (BAV). We aimed to evaluate the impact of prior BAV versus direct prosthesis implantation on myocardial injury occurring after (TAVR) with balloon-expandable prostheses. Methods and Results The DIRECTAVI (Direct Transcatheter Aortic Valve Implantation) trial, an open-label randomized study, demonstrated noninferiority of TAVR without BAV (direct TAVR group) compared with systematic BAV (BAV group) with the Edwards SAPIEN 3 valve.

Ruptured right Valsalva sinus into the right atrium due to infective endocarditis: a case report.

Rupture of Valsalva sinus remains a very rare and deadly complication of Valsalva sinus aneurysm with a high mortality rate. We report here the case of a 47-year-old man who presented to the emergency department with acute exercise-induced dyspnea, chest pain, and fever. Transthoracic (TTE) and transesophageal echocardiography (TEE) highlighted a rupture of the right Valsalva sinus in the right atrium due to infective endocarditis.

Prior Balloon Valvuloplasty Versus Direct Transcatheter Aortic Valve Replacement: Results From the DIRECTAVI Trial.

Objectives: The aim of this study was to evaluate device success of transcatheter aortic valve replacement (TAVR) using new-generation balloon-expandable prostheses with or without balloon aortic valvuloplasty (BAV).

Background: Randomized studies are lacking comparing TAVR without BAV against the conventional technique of TAVR with BAV.

Methods: DIRECTAVI (Direct Transcatheter Aortic Valve Implantation) was an open-label noninferiority study that randomized patients undergoing TAVR using the Edwards SAPIEN 3 valve with or without prior balloon valvuloplasty.

Hemodynamic Performances and Clinical Outcomes in Patients Undergoing Valve-in-Valve Versus Native Transcatheter Aortic Valve Implantation.

Valve-in-valve (ViV) transcatheter aortic valve implantation (TAVI) emerged has a less invasive treatment than surgery for patients with degenerated bioprosthesis. However, few data are currently available regarding results of ViV versus TAVI in native aortic valve. We aimed to compare hemodynamic performances and 1-year outcomes between patients who underwent ViV procedure and patients who underwent non-ViV TAVI.

Physician-Modified Thoracic Stent Grafts for the Arch After Surgical Treatment of Type A Dissection.

Background: This study evaluated the outcome of physician-modified thoracic stent grafts for the treatment of dissecting aortic arch aneurysms after surgical treatment of acute type A dissection.

Methods: From August 2016 through February 2018, 13 patients (8 men and 5 women) underwent thoracic endovascular aortic repair in which physician-modified thoracic stent grafts were used to treat dissecting aortic arch aneurysms after surgical treatment of acute type A dissection. Patients were a mean age of 70.

Five-Year Clinical Outcome and Valve Durability After Transcatheter Aortic Valve Replacement in High-Risk Patients.

Background: The FRANCE-2 registry (French Aortic National Corevalve and Edwards) previously reported good early- and medium-term clinical and echocardiographic efficacy for transcatheter aortic valve replacement. We here report 5-year follow-up results from the registry.

Methods: The registry includes all consecutive patients undergoing transcatheter aortic valve replacement for severe aortic stenosis in France.

Reverse extra-anatomic aortic arch debranching procedure allowing thoracic endovascular aortic repair of a chronic ascending aortic aneurysm.

A 79-year-old woman was admitted with a large chronic dissecting ascending aortic aneurysm starting 5 mm distal to the ostia of the left coronary artery and ending immediately proximal to the innominate artery. A reverse extra-anatomic aortic arch debranching procedure was performed. During the same operative time, through a transapical approach, a thoracic stent graft was deployed with the proximal landing zone just distal to the coronary ostia and the distal landing zone excluding the origin of the left common carotid artery.

Prognostic Impact of Calcium Score after Transcatheter Aortic Valve Implantation Performed With New Generation Prosthesis.

Calcium score (CS) is a well-known prognostic factor after transcatheter aortic valve implantation (TAVI) performed with first generation prosthesis but few data are available concerning new generation valves. The aim of this study was to evaluate if CS remains a prognostic factor after Sapien 3 and Evolut R valves implantation. Agatston CS was evaluated on multislice computed tomography before TAVI in 346 patients implanted with Sapien XT (n = 61), CoreValve (n = 57) devices, (group 1, n = 118), and with new generation Sapien 3 (n = 147), Evolut R (n = 81) prosthesis, (group 2, n = 228).

Experimental evaluation of homemade distal stent graft fenestration for thoracic endovascular aortic repair of type A dissection by a transapical approach.

Objective: The use of off-the-shelf stent grafts for thoracic endovascular aortic repair of type A dissections is limited by variability in both the length of the ascending aorta and the location of the proximal intimal tear. This experimental study aimed to assess the feasibility of using a physician-modified thoracic aortic stent graft to treat acute type A dissection by a transapical cardiac approach.

Methods: The experiments were performed on six cadaveric human heart, ascending aorta, aortic arch, and descending aorta specimens.

Persistent contamination of heater-cooler units for extracorporeal circulation cured by chlorhexidine-alcohol in water tanks.

Recently, surgical site infections due to non-tuberculous mycobacteria (NTM) have been linked to heater-cooler unit contamination. The European Centre for Disease Prevention and Control and manufacturers now recommend the use of hydrogen peroxide in filtered water to fill heater-cooler unit tanks. After implementation of these measures in our hospital, heater-cooler units became heavily contaminated by opportunistic waterborne pathogens such as Pseudomonas aeruginosa and Stenotrophomonas maltophilia.

Circulatory Support with Extracorporeal Membrane Oxygenation and/or Impella for Cardiogenic Shock During Myocardial Infarction.

Temporary mechanical circulatory support (TCS) is recommended for patients with profound cardiogenic shock (CS). Extracorporeal membrane oxygenation (ECMO) and Impella are possible TCS devices, but the device choice and the implantation timing are not definitely established, specifically during acute myocardial infarction. We have analyzed the respective use of ECMO or Impella (2.

Effect of Impella During Veno-Arterial Extracorporeal Membrane Oxygenation on Pulmonary Artery Flow as Assessed by End-Tidal Carbon Dioxide.

Peripheral veno-arterial extracorporeal membrane oxygenation (VA ECMO) exposes the patient to a pulmonary blood flow bypass and a left ventricle afterload increase. Impella, a catheter-mounted microaxial rotary pump, has been proposed for left ventricle (LV) unloading in combination with VA ECMO. In order to assess the effect of Impella on pulmonary flow and LV preload, we checked Doppler pulmonary artery velocity-time integral (pVTI) and LV diastolic diameter (LVED) by transesophageal echocardiography and end-tidal carbon dioxide (EtCO2) during a step-by-step increase in Impella flow (Impella ramp test).

Prior balloon valvuloplasty versus DIRECT transcatheter Aortic Valve Implantation (DIRECTAVI): study protocol for a randomized controlled trial.

Background: Balloon predilatation of the aortic valve has been regarded as an essential step during the transcatheter aortic valve implantation (TAVI) procedure. However, recent evidence has suggested that aortic valvuloplasty may cause complications and that high success rates may be obtained without prior dilatation of the valve. We hypothesize that TAVI performed without predilatation of the aortic valve and using new-generation balloon-expandable transcatheter heart valves is associated with a better net clinical benefit than TAVI performed with predilatation.

Late Outcomes of Transcatheter Aortic Valve Replacement in High-Risk Patients: The FRANCE-2 Registry.

Background: Transcatheter aortic valve replacement (TAVR) has revolutionized management of high-risk patients with severe aortic stenosis. However, survival and the incidence of severe complications have been assessed in relatively small populations and/or with limited follow-up.

Objectives: This report details late clinical outcome and its determinants in the FRANCE-2 (FRench Aortic National CoreValve and Edwards) registry.

Feasibility and Safety of Transcatheter Aortic Valve Implantation Performed Without Intensive Care Unit Admission.

Admission to the intensive care unit (ICU) is a standard of care after transcatheter aortic valve implantation (TAVI); however, the improvement of the procedure and the need to minimize the unnecessary use of medical resources call into question this strategy. We evaluated prospectively 177 consecutive patients who underwent TAVI. Low-risk patients, admitted to conventional cardiology units, had stable clinical state, transfemoral access, no right bundle branch block, permanent pacing with a self-expandable valve, and no complication occurring during the procedure.

Hybrid Aortic Repair of Dissecting Aortic Arch Aneurysm after Surgical Treatment of Acute Type A Dissection.

Background: The aim of this study was to evaluate the short-term and midterm results of hybrid repair of dissecting aortic arch aneurysms subsequent to surgical treatment of acute type A dissections.

Methods: Between 2003 and 2014, 7 consecutive patients, previously operated for acute type A dissection, underwent hybrid repair of their aortic arch for a dissecting aortic arch aneurysm (6 men, mean age 62 ± 11 years). Aneurysm formation requiring treatment in these aortic arches was observed from 2 to 20 years after the initial aortic dissection repair.

Management and outcome of patients supported with Impella 5.0 for refractory cardiogenic shock.

Introduction: Cardiogenic shock refractory to standard therapy with inotropes and/or intra-aortic balloon pump is accompanied with an unacceptable high mortality. Percutaneous left ventricular assist devices may provide a survival benefit for these very sick patients. In this study, we describe our experience with the Impella 5.

Vascular Complications and Bleeding After Transfemoral Transcatheter Aortic Valve Implantation Performed Through Open Surgical Access.

Major vascular complications (VC) remain frequent after transcatheter aortic valve implantation (TAVI) and may be associated with unfavorable clinical outcomes. The objective of this study was to evaluate the rate of VC after transfemoral TAVI performed using an exclusive open surgical access strategy. From 2010 to 2014, we included in a monocentric registry all consecutive patients who underwent transfemoral TAVI.

[Description of the two surgical myocardial revascularisation techniques].

A coronary artery bypass involves taking blood vessels from another part of the patient's body to bypass one or several major coronary stenoses. Coronary artery bypass using cardiopulmonary bypass and off-pump coronary artery bypass are the two methods used to revascularise the heart after a myocardial infarction.

Factors favoring retrograde aortic dissection after endovascular aortic arch repair.

Objective: To assess factors predisposing patients to retrograde type A aortic dissection (RTAD) who have undergone hybrid aortic arch repair.

Methods: From 2001 to 2013, 32 patients underwent hybrid aortic arch repair in our department: 19 in zone 1 and 13 in zone 0. Among these patients, 6 experienced RTAD (18.

Dynamics of the surgical microbiota along the cardiothoracic surgery pathway.

Human skin associated microbiota are increasingly described by culture-independent methods that showed an unexpected diversity with variation correlated with several pathologies. A role of microbiota disequilibrium in infection occurrence is hypothesized, particularly in surgical site infections. We study the diversities of operative site microbiota and its dynamics during surgical pathway of patients undergoing coronary-artery by-pass graft (CABG).
