Key result
ICD shock for AF linked to acute left main embolization in one anticoagulated HCM patient.
Why the study?
Atrial fibrillation is common in hypertrophic cardiomyopathy and is the most frequent cause of coronary artery embolism.
Case Report (n=1)
This case highlights the risk of acute coronary embolism following cardioversion of atrial fibrillation to sinus rhythm in a patient with hypertrophic cardiomyopathy, even while on rivaroxaban.
Atrial fibrillation (AF) is common in hypertrophic cardiomyopathy and it represents the most frequent cause of coronary artery embolism.We describe a male patient with hypertrophic cardiomyopathy with persistent AF, for which he consumed rivaroxaban. The patient received implantable cardioverter-defibrillator shocks for ventricular tachycardia, but he developed acute embolic occlusion in the left main coronary artery (LMCA) following the conversion of the AF rhythm into the sinus rhythm.

Zanganehfar et al. (2022) conducted a case report in Hypertrophic cardiomyopathy with persistent atrial fibrillation (n=1). Implantable cardioverter-defibrillator (ICD) shocks was evaluated on Acute embolic occlusion in the left main coronary artery. ICD shock conversion of persistent atrial fibrillation to sinus rhythm in 1 male patient with hypertrophic cardiomyopathy on rivaroxaban resulted in acute left main coronary artery embolization.
