Department of Cardiology and Catheterization Laboratories, Shonan Kamakura General Hospital, Okamoto 1370-1, Kamakura City, Kanagawa 247-8533, Japan.
Background: In patients with adult congenital heart disease (ACHD), significant atrioventricular valve regurgitation is an important risk factor for poor outcomes, such as heart failure. However, in many cases, transcatheter intervention may reduce the risk profile to avoid a high surgical risk.
Case Summary: A 44-year-old man with complex ACHD in the form of a double-inlet left ventricle, congenitally corrected transposition of the great arteries, pulmonary atresia, atrial septal defect, and patent ductus arteriosus was referred for the treatment of severe tricuspid regurgitation.

Hobart Healthcare Research Institute, London, United Kingdom.
Background: Understanding the conduction axis location aids in avoiding iatrogenic damage and guiding targeted heart rhythm therapy.
Objective: Cardiac structures visible with clinical imaging have been demonstrated to correlate with variability in the conduction system course. We aimed to standardize and assess the reproducibility of predicting the location of the atrioventricular conduction axis by cardiac computed tomography.

Department of Cardiovascular Medicine, University of Yamanashi, Chuo, Japan.
Introduction: Catheter ablation (CA) is the first-line treatment with a high success rate for patients with symptomatic Wolff-Parkinson-White syndrome, while three-dimensional (3D) mapping systems enable the identification of accessory pathways (APs). We aimed to develop a novel mapping method using wave-speed mapping (WSM) to determine AP locations and CA outcomes.
Methods And Results: This study included 19 patients diagnosed with atrioventricular (AV) reciprocating tachycardia.

Department of Cardiology, Hyogo Prefectural Awaji Medical Center, 1-1-137 Shioya, Sumoto 656-0021, Japan.
Background: Atrial standstill is characterized by the absence of atrial activity. We report a case of a patient with extensive atrial fibrosis who underwent electrophysiologic study (EPS) and electroanatomical mapping (EAM) to identify surviving atrial sites amenable for pacemaker lead implantation.
Case Summary: A 72-year-old man with persistent atrial fibrillation (AF) and atrial functional mitral regurgitation/tricuspid regurgitation (MR/TR) underwent a Cox-Maze surgery, mitral and tricuspid valve repair, and biatrial plication.
