1-Year Outcomes After Edge-to-Edge Valve Repair for Symptomatic Tricuspid Regurgitation

2019

Abstract Objectives The purpose of this study was to evaluate procedural and 1-year clinical and echocardiographic outcomes of patients treated with tricuspid edge-to-edge repair. Background Transcatheter edge-to-edge repair has been successfully performed in selected patients with symptomatic tricuspid regurgitation (TR) and high risk for surgery, but outcome data are sparse. Methods This analysis of the multicenter international TriValve (Transcatheter Tricuspid Valve Therapies) registry included 249 patients with severe TR treated with edge-to-edge repair in compassionate and/or off-label use. Clinical and echocardiographic outcomes were prospectively collected and retrospectively analyz…

Value of Echocardiographic Right Ventricular and Pulmonary Pressure Assessment in Predicting Transcatheter Tricuspid Repair Outcome

2020

The aim of this study was to assess the value of echocardiographic right ventricular (RV) and systolic pulmonary artery pressure (sPAP) assessment in predicting transcatheter tricuspid edge-to-edge valve repair (TTVR) outcome.RV dysfunction and pulmonary hypertension are associated with poor prognosis and are systematically sought during tricuspid regurgitation evaluation. The value of echocardiographic assessment in predicting TTVR outcome is unknown.Data were taken from the TriValve (Transcatheter Tricuspid Valve Therapies) registry, which includes patients undergoing TTVR at 14 European and North American centers. The primary outcome was 1-year survival free from hospitalization for hear…

2019

Abstract Background Underweight and obesity represent classical risk factors for patients undergoing cardiac surgery or interventional treatment. The multicentre German Transcatheter Mitral Valve Interventions (TRAMI) registry comprises a large and prospectively enrolled real-world cohort of patients treated by MitraClip implantation. Aims The current analysis examines the impact of underweight, overweight and obesity on intra-hospital, short and long-term outcomes in patients treated by MitraClip therapy. Methods and results From 08/2010 until 07/2013, 799 patients (age 75.3±8.6 years, male gender 60.7%, median logistic EuroSCORE 20% [12; 31], functional mitral regurgitation (MR): 69.3%) w…

Permanent Pacemaker Lead Insertion Connected to an External Pacemaker Generator for Temporary Pacing After Transcatheter Aortic Valve Implantation.

2019

Abstract Background Outcomes after transcatheter aortic valve implantation (TAVI) have been demonstrated to be at least equivalent in the short term compared to surgical valve implantation (SAVI). However, Conduction abnormalities are more common after TAVI than SAVI and the need for permanent pacemaker implantation is more common after TAVI with the currently commercially available self-expanding valves than after SAVI. Temporary pacemaker implantation may be associated with inability to ambulate, lead migration or perforation and infection. Depending on the monitoring system, some arrhythmias may not be detected. We examined the feasibility and safety of permanent pacemaker lead implantat…

Chronic total coronary occlusions and the Occluded Artery Trial. A critical appraisal.

2008

The OAT trial and its angiographic substudy TOSCA-2, along with a number of published commentaries, represents examples of over-interpretation of clinical study results. A study that achieved no statistically significant result for any of the study endpoints can only claim to have proven that their null hypothesis cannot be rejected. The lack of power due to a reduction of patient numbers by one third, and an unexpected low event rate, makes it not unlikely that another trial would be able to disprove the null hypothesis. These statistical facts should be accepted by the authors and commentators. Instead, the inconclusive results were interpreted in such a way that they might apply to patie…

Alcohol-Mediated Renal Sympathetic Neurolysis for the Treatment of Hypertension: The Peregrine™ Infusion Catheter.

2020

Renal sympathetic denervation using conventional non-irrigated radiofrequency catheters has potential technical shortcomings, including limited penetration depth and incomplete circumferential nerve damage, potentially impacting therapeutic efficacy. Against this background, second generation multi-electrode, radiofrequency and ultrasound renal denervation systems have been developed to provide more consistent circumferential nerve ablation. Irrigated catheters may allow deeper penetration while minimizing arterial injury. In this context, catheter-based chemical denervation, with selective infusion of alcohol, a potent neurolytic agent, into the perivascular space, may minimize endothelial…

Initial and long-term antithrombotic therapy after left atrial appendage closure with the WATCHMAN

2020

Abstract Background Evidence regarding post-procedural antithrombotic regimes other than used in randomized trials assessing percutaneous left atrial appendage (LAA) closure is limited. Purpose The present work aimed to compare different antithrombotic strategies applied in the real-world EWOLUTION study. Methods A total of 998 patients with successful WATCHMAN implantation at 47 centers were available for the present analysis. The composite ischemic endpoint of stroke, TIA, systemic embolism and device thrombus as well as the bleeding endpoint defined as at least major bleeding according to BARC were assessed during an initial period (from implant until first medication change) and long-te…

Outcomes of transcatheter tricuspid valve intervention by right ventricular function: a multicentre propensity-matched analysis

2021

BACKGROUND Tricuspid regurgitation (TR) has a poor prognosis and limited treatment options and is frequently accompanied by right ventricular (RV) dysfunction. Transcatheter tricuspid valve interventions (TTVI) to reduce TR have been shown to be safe and feasible with encouraging early results. Patient selection for TTVI remains challenging, with the role of right ventricular (RV) function being unknown. AIMS The aims of this study were 1) to investigate survival in a TTVI-treated patient population and a conservatively treated TR population, and 2) to evaluate the outcome of TTVI as compared to conservative treatment stratified according to the degree of RV function. METHODS We studied 684…

9-Month Clinical and Angiographic Outcomes of the COBRA Polyzene-F NanoCoated Coronary Stent System

2016

Abstract Objectives The aim of this study was to assess the safety and effectiveness of the COBRA Polyzene-F NanoCoated Coronary Stent System (CeloNova Biosciences, San Antonio, Texas) for the treatment of de novo coronary artery lesions. Background Polyzene-F–coated coronary stents have shown reduced thrombogenicity and inflammation in preclinical studies. Methods Patients with de novo coronary artery lesions meeting eligibility criteria were enrolled in a nonrandomized, prospective clinical trial. The primary endpoint was target vessel failure (TVF) (defined as a composite of cardiac death, myocardial infarction, or clinically driven target vessel revascularization) at 9 months. A pre-spe…

Derivation and Validation of a Chronic Total Coronary Occlusion Intervention Procedural Success Score From the 20,000-Patient EuroCTO Registry

2019

Abstract Objectives The aim was to establish a contemporary scoring system to predict the outcome of chronic total occlusion coronary angioplasty. Background Interventional treatment of chronic total coronary occlusions (CTOs) is a developing subspecialty. Predictors of technical success or failure have been derived from datasets of modest size. A robust scoring tool could facilitate case selection and inform decision making. Methods The study analyzed data from the EuroCTO registry. This prospective database was set up in 2008 and includes >20,000 cases submitted by CTO expert operators (>50 cases/year). Derivation (n = 14,882) and validation (n = 5,745) datasets were created to develop a …

2013

This document by an expert panel of the International Society for Neurovascular Disease is aimed at presenting current technique and interpretation of catheter venography of the internal jugular veins, azygous vein and other veins draining the central nervous system. Although interventionalists agree on general rules, significant differences exist in terms of details of venographic technique and interpretations of angiographic pictures. It is also suggested that debatable findings should be investigated using multimodal diagnostics. Finally, the authors recommend that any publication on chronic cerebrospinal venous insufficiency should include detailed description of venographic technique u…
