The Impact of the COVID-19 Pandemic on Cardiac Electrophysiology Training: A Survey Study.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has resulted in a significant decrease in volume of electrophysiology (EP) procedures. There has been concern that trainees may not achieve the procedural numbers required to graduate as independent electrophysiologists within the usual timeline. We sought to determine the impact of the COVID-19 pandemic on the percentage of clinical cardiac EP (CCEP) fellows in jeopardy of not meeting procedural volume requirements and overall sentiments regarding preparedness of fellows for independent practice. METHODS: We surveyed CCEP fellows and program directors about baseline procedural volumes, curriculum changes due to the pandemic, and attitudes about preparedness for board examinations and independent practice. RESULTS: Ninety-nine fellows and 27 program directors responded to the survey. Ninety-eight percent of responding fellows reported a decrease in procedural volume as a result of the pandemic. Program directors reported an overall decrease in annual number of ablations and device procedures performed by each fellow during the 2019-2020 academic year compared to the preceding year. Despite this, a minority of fellows and program directors reported concerns about meeting Accreditation Council for Graduate Medical Education procedural requirements for devices (9% and 4%, respectively) and ablation (19% and 9%) or preparedness for independent practice after a 2-year fellowship. CONCLUSIONS: The COVID-19 pandemic has resulted in a decrease in procedural volume for CCEP trainees, but the majority of fellows and program directors do not anticipate major barriers to timely graduation. This may change with COVID-19 resurgence and further interruptions in training.

Gender differences in ventricular arrhythmia recurrence in patients with coronary artery disease and implantable cardioverter-defibrillators.

OBJECTIVES: We sought to determine whether men and women with coronary artery disease (CAD) and implantable cardioverter-defibrillators (ICDs) differ in frequency of arrhythmia recurrence and whether gender differences are independent of clinical, electrocardiographic, and electrophysiologic characteristics. BACKGROUND: Epidemiologic studies show that women have a lower rate of sudden cardiac death (SCD) than men, even among patients with CAD. Whether this is due to differing susceptibilities to ischemia or to arrhythmia is unknown. METHODS: The clinical records and ICD data disks of 340 men and 59 women with CAD who received an ICD between June 1990 and June 2000 were reviewed. Ventricular tachycardia (VT) or ventricular fibrillation (VF) recurrences were compared between genders and relationship with other factors was analyzed. RESULTS: Sustained VT/VF occurred in 52% of men and 34% of women (p < 0.01). Men experienced more total VT/VF events (p < 0.01), more shock-treated VT/VF events (p < 0.03), more electrical storms (p < 0.001), and had VT/VF on more days in follow-up (p < 0.01). Gender differences were independent of measured clinical, electrocardiographic, and electrophysiologic factors. In stratified analyses, the gender differences in VT/VF recurrence were greatest in patients presenting with sustained monomorphic VT and those with inducible VT at electrophysiology study. CONCLUSIONS: Women were less likely to experience VT/VF, and had fewer VT/VF episodes, than men. These findings were strongest in patients with evidence of a stable anatomic VT circuit: those with clinical or electrophysiologically induced VT. This study suggests that differing susceptibility to arrhythmia triggering may underlie the known differences in SCD rates between men and women.
