Implantation of a left bundle branch area pacemaker can be complicated by a septal coronary artery fistula, potentially leading to ventricular arrhythmias.
A 51-year-old man with a mixed-phenotype cardiomyopathy was referred for coronary angiography because of new-onset episodes of ventricular arrythmias. At his initial presentation in 2014, he was diagnosed with hypertrophic cardiomyopathy, presumably related to poorly controlled arterial hypertension.
Bradt et al. (Wed,) studied this question.
