A 39-year-old man presented with recurrent syncope. A 12-lead electrocardiogram and a 24-h Holter recording demonstrated atypical persistent Mobitz type I and high-degree atrioventricular block, respectively. The functional nature of the atrioventricular block was confirmed by atropine challenge, exercise testing, and electrophysiological study. The patient was successfully treated with a cardioneuroablation procedure. ().

Approaching Universal Prenatal Detection of Significant Cardiovascular Malformations in Nevada.
Prenat Diagn
December 2024
Children's Heart Center Nevada, Las Vegas, Nevada, USA.
Objective: To report our recent experience with prenatal detection of significant cardiovascular malformations (CVMs) in Nevada's state-wide maternal population receiving prenatal care.
Methods: We queried our databases for those with significant CVMs diagnosed pre- or postnatally between May 1, 2021, and April 30, 2024. We defined CVMs as those that required, would have required, or will likely require a therapeutic procedure in the first 12 months.
Potential of right ventricular function assessment with echocardiography in transcatheter aortic valve replacement.

Department of Cardiology, Thomas Jefferson University, Philadelphia, PA, 19107, USA.
Background: Right ventricular (RV) function assessment by echocardiography can be challenging due to its complex morphology. Also, increasing use of sedation rather than general anesthesia for transfemoral approach transcatheter aortic valve replacement (TAVR) reduces the need for intraoperative transesophageal echocardiography (TEE). Recent clinical studies have demonstrated the importance of 3-dimensional (3D) echocardiography and a longitudinal strain for RV function assessment.

Article Synopsis
- The study compares outcomes of left atrial appendage closure combined with catheter ablation (LAACCA) vs. catheter ablation alone in patients with atrial fibrillation and heart failure.
- Results show that LAACCA leads to longer hospital stays, higher mortality rates, and increased hospitalization costs compared to catheter ablation alone.
- Post-procedure complications were also more common in the LAACCA group, including higher rates of myocardial ischemia and complete atrioventricular block.
Filamin C Truncating Variant Causes Severe Conduction Defects and Mild Cardiomyopathy.
Cureus
November 2024
Department of Medical Genetics, Institute of Science Tokyo, Tokyo, JPN.
Filamin C (FLNC), recently identified as a causative gene of cardiomyopathy, is widely expressed in cardiomyocytes and is involved in signal transduction between the sarcomere and the plasma membrane. In general, the FLNC truncating variant causes severe dilated cardiomyopathy. A 70-year-old female was referred to our hospital with advanced conduction defects and underwent pacemaker implantation.

Department of Electrocardiology, The Third Affiliated Hospital of Wenzhou Medical University, No.108 WansongRoad, Wenzhou, 325200, People's Republic of China.
Background: Ventricular separation is a multipart, extensive disease of the heart that hinders the electrical conduction of the cardiac system ventricular muscle, causing a bidirectional conduction block. The occurrence of ventricular separation suggests that the myocardium is in a state of severe ischemia, and the prognosis is generally poor. Herein, we present arescue case in which the extremely rare phenomenon of ventricular separation developed and was documented in realtime.
