Monomorphic ventricular arrhythmias (MMVA), while often benign in athletes with a structurally normal heart, are also associated with a unique subset of idiopathic and malignant substrates that must be clearly defined. A comprehensive evaluation for structural and\/or electrical heart disease is required in order to exclude cardiac conditions that increase risk of SCD with exercise, such as hypertrophic cardiomyopathy and arrhythmogenic right ventricular cardiomyopathy. Unique issues for physicians who manage this population include navigating athletes through the decision of whether they can safely continue their chosen sport. In the absence of structural heart disease, therapies such as radiofrequency catheter ablation are very effective for certain arrhythmias and may allow for return to competitive sports participation. In this comprehensive review, we summarise the recommendations for evaluating and managing athletes with MMVA.<\/p>","DOI":"10.15420\/aer.2019.19.3","type":"journal-article","created":{"date-parts":[[2019,5,8]],"date-time":"2019-05-08T11:46:36Z","timestamp":1557315996000},"page":"83-89","source":"Crossref","is-referenced-by-count":6,"title":["Monomorphic Ventricular Arrhythmias in Athletes"],"prefix":"10.15420","volume":"8","author":[{"given":"Jeffrey J","family":"Hsu","sequence":"first","affiliation":[{"name":"UCLA Sports Cardiology Center, Los Angeles, CA, US; Ahmanson-UCLA Cardiomyopathy Center, Los Angeles, CA, US"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ali","family":"Nsair","sequence":"additional","affiliation":[{"name":"UCLA Sports Cardiology Center, Los Angeles, CA, US; Ahmanson-UCLA Cardiomyopathy Center, Los Angeles, CA, US"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jamil A","family":"Aboulhosn","sequence":"additional","affiliation":[{"name":"UCLA Sports Cardiology Center, Los Angeles, CA, US; Ahmanson-UCLA Cardiomyopathy Center, Los Angeles, CA, US"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamara B","family":"Horwich","sequence":"additional","affiliation":[{"name":"UCLA Sports Cardiology Center, Los Angeles, CA, US; Ahmanson-UCLA Cardiomyopathy Center, Los Angeles, CA, US"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ravi H","family":"Dave","sequence":"additional","affiliation":[{"name":"UCLA Sports Cardiology Center, Los Angeles, CA, US"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin M","family":"Shannon","sequence":"additional","affiliation":[{"name":"UCLA Sports Cardiology Center, Los Angeles, CA, US; Ahmanson-UCLA Cardiomyopathy Center, Los Angeles, CA, US; UCLA Department of Pediatrics David Geffen School of Medicine at UCLA, Los Angeles, CA, US"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noel G","family":"Boyle","sequence":"additional","affiliation":[{"name":"UCLA Cardiac Arrhythmia Center, Los Angeles, CA, US"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kalyanam","family":"Shivkumar","sequence":"additional","affiliation":[{"name":"UCLA Cardiac Arrhythmia Center, Los Angeles, CA, US"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jason S","family":"Bradfield","sequence":"additional","affiliation":[{"name":"UCLA Sports Cardiology Center, Los Angeles, CA, US; UCLA Cardiac Arrhythmia Center, Los Angeles, CA, US"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"6096","published-online":{"date-parts":[[2019,5,2]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","first-page":"2412","DOI":"10.1016\/j.jacc.2015.09.041","article-title":"Eligibility and disqualification recommendations for competitive athletes with cardiovascular abnormalities: Task Force 9: Arrhythmias and conduction defects: A scientific statement from the American Heart Association and American College of Cardiology","volume":"66","author":"Zipes","year":"2015","unstructured":"1.
