Key result
Large hiatal hernia linked to recurrent AFib via direct mechanical compression of the left atrium.
Why the study?
Hiatal hernia is a potential risk factor for atrial fibrillation that requires scientific investigation due to its anatomical proximity to the heart and high prevalence in AF patients.
Case Report (n=1)
This case report highlights hiatal hernia as a potential, under-recognized trigger for atrial fibrillation in patients lacking traditional risk factors.
Answers are grounded in this paper and cite their sources.
Hiatal hernia may trigger AF via LA compression in select patients; single case leaves open causal role and need for prospective study.
Atrial fibrillation is a commonly encountered clinical entity with various cardiovascular consequences. Common risk factors include alcohol abuse, hyperthyroidism, mitral stenosis, hypertension, diabetes mellitus, and coronary artery disease. Another risk factor, yet under scientific scrutiny, is hiatal hernia. This anatomical abnormality, due to its proximity to the heart and high prevalence in atrial fibrillation patients, has merited scientific investigation to determine if an association truly exists between this gastrointestinal pathology and atrial fibrillation. The case herein is of an 81-year-old hospitalized female with a hiatal hernia who was recorded to have recurrent episodes of atrial fibrillation in the absence of traditional risk factors for arrhythmogenesis.

Malik et al. (2021) conducted a case report in Atrial fibrillation (n=1). Hiatal hernia was evaluated on Occurrence of atrial fibrillation. A large hiatal hernia was observed to trigger recurrent episodes of atrial fibrillation in an 81-year-old female, likely due to direct mechanical compression of the left atrium.
