Cubital vein access provides a practical alternative to internal jugular vein access for coronary sinus catheter placement.

Background: Insertion of electrode catheters into the coronary sinus (CS) through the right internal jugular vein (RIJV) carries risks of pneumothorax and severe hematoma formation. This study was performed to compare the safety and feasibility of catheterization through the left cubital superficial vein versus the RIJV.

Methods: This prospective nonrandomized study involved consecutive patients who underwent catheter ablation from September 2021 to February 2023.

Asymmetric remodeling between the left and right atria in patients with advanced interatrial block and atrial fibrillation.

Background: Advanced interatrial block (A-IAB) on electrocardiography (ECG) represents the conduction delay between the left and right atria. We investigated the association of A-IAB with left and right atrial (LA/RA) remodeling in patients with atrial fibrillation (AF).

Methods: We enrolled 74 patients who underwent ECG, cardiac computed tomography (CCT), and echocardiography during sinus rhythm before catheter ablation of AF.

Asymptomatic Coarctation of the Aorta in Adults with Preserved Exercise Capacity.

We herein report a case of coarctation of the aorta (CoA) in an asymptomatic adult who had a preserved exercise capacity. A 56-year-old man with mild hypertension exhibited left ventricular hypertrophy on an electrocardiogram during an annual medical checkup. Echocardiography showed a bicuspid aortic valve and cor triatriatum sinister, and subsequent computed tomography revealed CoA with developed collaterals.

Comparison of Radiofrequency and Cryoballoon Pulmonary Vein Ablation for the Early and Late Recurrence of Atrial Fibrillation.

Objective Early recurrence (ER) after pulmonary vein isolation (PVI) for atrial fibrillation (AF) is expected to resolve within the recommended 3-month blanking period, irrespective of the ablation device used. To compare the occurrence and relationship of AF within the blanking period and subsequent late recurrence (LR) with radiofrequency (RF) and cryoballoon (CB) ablation. Methods A retrospective analysis of 294 patients (mean age=62±9, 70.

Lead dislodgement after a very long-term period of cardiac implantable electronic device implantation.

A 74-year-old man was admitted for a second replacement of a transvenous implantable cardioverter-defibrillator (ICD) generator at 15 years after implantation. Postoperatively, electrocardiographic monitoring showed atrial lead malfunction. Chest X-ray revealed that the tip of the active fixation atrial lead was dislocated.
