Many patients undergoing transcatheter aortic valve implantation (TAVI) have a pre-existing, permanent pacemaker (PPM) or receive one as consequence of the procedure. We hypothesised that chronic pacing may adverse effects on TAVI outcomes.Four groups in Placement Aortic Transcatheter Valves (PARTNER) trial and registries were compared: prior PPM (n=586), new (n=173), no (n=1612), left bundle branch block (LBBB)/no (n=160). At 1 year, PPM, LBBB/no had higher all-cause mortality than (27.4%,...
Background— This study sought to evaluate the impact of atrial fibrillation (AF) on clinical outcomes in patients undergoing transcatheter aortic valve replacement. Methods and Results— Data were evaluated 1879 with baseline discharge ECGs who underwent replacement Placement AoRTic TraNscathetER Valve (PARTNER) trial. A total 1262 manifested sinus rhythm (SR) at baseline/SR discharge, 113 SR baseline/AF 470 AF discharge. Patients converted from by had highest rates all-cause mortality 30...
Abstract Objective This study evaluated the impact of daily ECG (electrocardiogram) self‐recordings on time to documented recurrent atrial fibrillation (AF) or flutter (AFL) and treatment arrhythmia in patients undergoing catheter radiofrequency ablation (RFA) direct current cardioversion (DCCV) for AF/AFL. Background AF recurrence rates after RFA DCCV are 20% 45% 60% 80%, respectively. Randomized trials comparing mobile devices standard care have not been performed an AF/AFL population...
<h3>Importance</h3> Critical illness, a marked inflammatory response, and viruses such as SARS-CoV-2 may prolong corrected QT interval (QTc). <h3>Objective</h3> To evaluate baseline QTc on 12-lead electrocardiograms (ECGs) ensuing changes among patients with without COVID-19. <h3>Design, Setting, Participants</h3> This cohort study included 3050 aged 18 years older who underwent testing had ECGs at Columbia University Irving Medical Center from March 1 through May 1, 2020. Patients were...
Background Cardiovascular involvement in coronavirus disease 2019 (COVID‐19) is common and leads to worsened mortality. Diagnostic cardiovascular studies may be helpful for resource appropriation identifying patients at increased risk death. Methods Results We analyzed 887 (aged 64±17 years) admitted with COVID‐19 from March 1 April 3, 2020 New York City 12 lead electrocardiography within 2 days of diagnosis. Demographics, comorbidities, laboratory testing, including high sensitivity cardiac...
Electrocardiographic characteristics in COVID-19-related mortality have not yet been reported, particularly racial/ethnic minorities.We reviewed demographics, laboratory and cardiac tests, medications, rhythm proximate to death or initiation of comfort care for patients hospitalized with a positive SARS-CoV-2 reverse-transcriptase polymerase chain reaction three New York City hospitals between March 1 April 3, 2020 who died. We described clinical compared factors contributing toward...
The aim of this study was to assess the incidence and prognostic impact early late postoperative atrial fibrillation or flutter (POAF) in patients with severe aortic stenosis (AS) treated transcatheter valve replacement (TAVR) surgical (SAVR). There is an ongoing controversy regarding incidence, recurrence rate, (in-hospital) POAF (postdischarge) AS undergoing TAVR SAVR. In PARTNER (Placement Aortic Transcatheter Valve) 3 trial, at low risk were randomized Analyses performed as-treated...
This study sought to determine the electrophysiological predictors of acute procedural success and post-ablation recurrence atrial tachyarrhythmias (ATs) in our adult congenital heart disease (ACHD) population undergoing catheter ablation for treatment AT.Catheter is frequently performed treat persistent AT ACHD. The have not been well studied ACHD population.The authors a retrospective all ablations patients between December 1, 2005, July 20, 2017, at Columbia University Medical Center....
Patients with end‐stage cardiomyopathy and congestive heart failure are increasingly undergoing implantation left ventricular assist devices (LVADs). In addition, implantable cardioverter‐defibrillator (ICD) therapy has been proven to be an important part of the treatment for cardiomyopathy/congestive failure. Previous reports have noted a potential dramatic electromagnetic interference from LVADs on ICDs that cause impaired telemetry communication between ICD programmer. Such necessitated...
Leadless pacemakers (LPMs) have been shown to lower postoperative complications than traditional permanent but there no studies on the outcomes of LPMs in patients with transcatheter heart valve replacements (THVRs). This study determined compared transvenous single-chamber (SCPs) post-THVR.This is a retrospective single-center including 10 who received post-THVR between February 2017 and August 2018 comparison group 23 SCP July 2008 2018. LPM or was implanted at discretion...
The COVID-19 pandemic has greatly altered the practice of cardiac electrophysiology around world for foreseeable future. Professional organizations have provided guidance practitioners, but real-world examples consults and responsibilities electrophysiologists face during a surge patients is lacking.In this observational case series we report on 29 consecutive inpatient consultations at major academic medical center in New York City, epicenter United States, 2 week period from March 30-April...
