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…

Effects of hospital facilities on patient outcomes after cancer surgery

2022

© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal,…

Timing of surgery following SARS-CoV-2 infection: an international prospective cohort study

2021

Peri-operative SARS-CoV-2 infection increases postoperative mortality. The aim of this study was to determine the optimal duration of planned delay before surgery in patients who have had SARS-CoV-2 infection. This international, multicentre, prospective cohort study included patients undergoing elective or emergency surgery during October 2020. Surgical patients with pre-operative SARS-CoV-2 infection were compared with those without previous SARS-CoV-2 infection. The primary outcome measure was 30-day postoperative mortality. Logistic regression models were used to calculate adjusted 30-day mortality rates stratified by time from diagnosis of SARS-CoV-2 infection to surgery. Among 140,231…

Global variation in anastomosis and end colostomy formation following left-sided colorectal resection

2019

Background: End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection. Methods: This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associ…
