A man with double inlet left ventricle and severe subpulmonary stenosis underwent a Fontan operation at the age of 29 years. Eight years later he developed atrial flutter with complete heart block. To avoid a further thoracotomy, a unipolar carbon tipped electrode was placed into the posterior cardiac vein via the coronary sinus. More than 8 years after implantation of the original lead, and after two generator changes, telemetric thresholds remain between 1.8-2.1 volts. Percutaneous transvenous ventricular pacing via the coronary sinus can produce an excellent long-term result and should be the initial approach of choice after a Fontan-type operation.

Background: The coronary atrial circulation is the network of vessels that supply blood to the atria, originating from the left circumflex and right coronary arteries. Current descriptions of this arterial system are based on anatomical studies with a limited number of patients, predominantly male. In addition, there is a lack of consensus its angiographic nomenclature.

Heart failure is a prevalent global health issue. Heart failure with preserved ejection fraction (HFpEF), which already represents half of all heart cases worldwide, is projected to further increase, driven by aging populations and rising cardiovascular risk factors. Effective therapies for HFpEF remain limited, particularly due to its pathophysiological heterogeneity and incomplete understanding of underlying pathomechanisms and implications.

Background: Junctional rhythm (JR) frequently occurs during radiofrequency (RF) ablation procedures targeting the slow pathway (SP) for atrioventricular nodal re-entrant tachycardia (AVNRT), signaling successful ablation. Two types of JR have been noticed: typical JR as His activation preceding atrial activation, and atypical JR as atrial activation preceding the His activation. Nevertheless, the origin and characteristics of JR remain incompletely defined.

Heart failure (HF) increases the risk of developing atrial fibrillation (AF), leading to increased morbidity and mortality. Therefore, better prediction of this risk may improve treatment strategies. Although several predictors based on clinical data have been developed, the establishment of a transcriptome-based predictor of AF incidence in HF has proven to be more problematic.

Background: Valve sparing aortic root replacement (VSARR) is a treatment for aortic root dilatation and aortic regurgitation (AR), which preserves the aortic valve. However, AR may recur, and redo surgery often carries high risk. Transcatheter aortic valve replacement (TAVR) can be performed but there is a paucity of literature to guide procedural planning.
