A coronary artery aneurysm arising from a sinus node artery with a fistula is an extremely rare congenital anomaly. We report a rare case of a minimally invasive repair of a sinus node artery aneurysm with a fistula in the right atrium.

Adenosine is extensively utilized in myocardial stress perfusion imaging for the detection and risk stratification of coronary artery disease. It has a well-established safety profile. The majority of the undesirable effects experienced during adenosine infusion are transient (owing to its brief half-life of ~10 s) and arise from the stimulation of receptors in the atrio-ventricular (AV) node (AV block) and bronchial smooth muscles (bronchospasm).

Induced pluripotent stem cell (iPSC)-derived biological pacemakers have emerged as an alternative to traditional electronic pacemakers for managing cardiac arrhythmias. While effective, electronic pacemakers face challenges such as device failure, lead complications, and surgical risks, particularly in children. iPSC-derived pacemakers offer a promising solution by mimicking the sinoatrial node's natural pacemaking function, providing a more physiological approach to rhythm control.

Introduction/objective: Atrial fibrillation (AF) could present with slow ventricular-response; bradycardia could facilitate the emergence of AF. The conviction that one "does not succumb" from bradycardia as an escape rhythm will emerge unless one sustains a fatal injury following syncope is in stark difference with ventricular tachyarrhythmia (VA), which may promptly cause cardiac arrest. However, this is not always the case, as a life-threatening situation may emerge during the bradycardic episode, i.

To broaden our understanding of bradyarrhythmias and conduction disease, we performed common variant genome-wide association analyses in up to 1.3 million individuals and rare variant burden testing in 460,000 individuals for sinus node dysfunction (SND), distal conduction disease (DCD) and pacemaker (PM) implantation. We identified 13, 31 and 21 common variant loci for SND, DCD and PM, respectively.
