Welcome to the CardioNerds Atrial Fibrillation Series Page! 

This CardioNerds Atrial Fibrillation series is a multi-institutional collaboration made possible by contributions of stellar fellow leads and expert faculty from several programs, led by series co-chairs, Dr. Kelly Arps and Dr. Colin Blumenthal.

This series is supported by an educational grant from the Bristol Myers Squibb and Pfizer Alliance. All CardioNerds content is planned, produced, and reviewed solely by CardioNerds


Dr. Daniel Ambinder (CardioNerds Co-Founder), Dr. Kelly Arps (Series Co-Chair and EP fellow at Duke University), Dr. Stephanie Fuentes Rojas (FIT Lead and EP fellow at Houston Methodist), and Dr. Ingrid Hsiung (Cardiology Fellow at Baylor Scott & White Health) discuss situational assessment of stroke and bleeding risk with expert faculty Dr. Hafiza Khan (Electrophysiologist at Baylor Scott & White Health). In this episode, we discuss stroke and bleeding risk in specific situations such as prior to cardioversion, triggered episodes, and perioperatively. These are scenarios that are commonly encountered and pose specific challenges. Episode notes were drafted by Dr. Stephanie Fuentes. Audio editing by CardioNerds Academy InternDr. Maryam Barkhordarian.

CardioNerds Amit GoyalDr. Colin BlumenthalDr. Kelly Arps and Dr. Justice Oranefo discuss mechanical stroke prevention in atrial fibrillation with Dr. Christopher Ellis, cardiac electrophysiology lab director and director of the left atrial appendage closure program at Vanderbilt University. There has been a significant increase in the number of patients undergoing left atrial appendage occlusion (LAAO). This trend is expected to continue with current and upcoming clinical data on this topic. In this episode we dive into the rationale behind LAAO and explore several historical facts. We then proceed to the current state of practice including currently available options, appropriate indications, post op care, and potential complications. Notes were drafted by Dr. Justice Oranefo.

CardioNerds (Amit Goyal), Dr. Colin Blumenthal (CardioNerds Academy House Faculty Leader and FIT at the University of Pennsylvania), and Dr. Anjali Wagle (CardioNerds Ambassador and FIT at Johns Hopkins University), discuss the baseline assessment of stroke and bleeding risk in patients with atrial fibrillation (AF) with Dr. Elaine Hylek. Dr. Hylek is a professor of medicine at the Boston University School of Medicine and is the Director of the Thrombosis and Anticoagulation Service at Boston Medical Center. Stroke is a potentially devastating and preventable complication of AF. Understanding the balance between stroke and bleeding risk is crucial in determining who should be on anticoagulation. Join us to discuss this topic! In the next episode of the series, we will discuss situational risk assessment in the context of peri-cardioversion, peri-procedural status, triggered atrial fibrillation, and more.

CardioNerds (Dr. Kelly ArpsDr. Colin BlumenthalDr. Dan Ambinder, and Dr. Teodora Donisan) discuss the screening, detection, and diagnosis of atrial fibrillation (AF) with Dr. Ben Freedman. AF is frequently undiagnosed and its first manifestation can be a debilitating stroke. European and American guidelines differ slightly with regards to guidelines for AF screening in asymptomatic individuals. There are multiple methods available to screen for AF; the setting and the clinical scenario can help guide the choice. Consumer-led screening has its own challenges, as it can detect AF in a younger population where we should prioritize aggressive management of risk factors and comorbidities. There is uncertainty regarding the minimum AF burden that increases thromboembolic risk, however a high CHAD2S2-VASc score remains the strongest predictor of stroke risk independent of AF burden. Perioperative AF associated with non-cardiac surgery has increased risk of future stroke and adverse cardiac outcomes and should likely be treated as a new diagnosis of chronic AF.   

Atrial fibrillation may reach pandemic proportions in the next 2-3 decades. Factors that drive this phenomenon have been studied in predominantly White populations, leading to a significant underrepresentation of certain racial/ethnic groups in atrial fibrillation epidemiological studies. Most atrial fibrillation epidemiology studies suggest that the non-Hispanic Black population has a lower incidence/prevalence of atrial fibrillation, despite a higher risk factor burden (“Afib paradox”). At the same time, non-Hispanic Blacks have worse outcomes compared to the White population and underrepresented populations and women are less likely than White men to receive optimal guideline-based therapies for atrial fibrillation.

In this episode, CardioNerds Dr. Kelly Arps (Co-Chair Atrial Fibrillation series, Cardiology fellow at Duke University), Dr. Colin Blumenthal (Co-Chair Atrial Fibrillation series, CardioNerds Academy House Faculty Leader for House Jones, Cardiology fellow at the University of Pennsylvania), and Dr. Dinu-Valentin Balanescu (CardioNerds Academy Faculty for House Jones, rising internal medicine chief resident at Beaumont Hospital), discuss with Dr. Larry Jackson (cardiac electrophysiologist and Vice Chief of Diversity, Equity, and Inclusion in the Division of Cardiology at Duke University) about atrial fibrillation epidemiology and health equity, challenges and possible solutions to improving diversity in clinical trials, and race/ethnicity/sex/gender differences in the detection, management, and outcomes of atrial fibrillation.
