In a series of 14 patients undergoing transseptal catheterization for ablation of left-sided accessory pathways, hydrogen appearance time was used to detect left-to-right shunting after removal of the catheter. Six of the 12 patients who had no evidence of shunt before catheterization had evidence of shunting after the procedure.

Atrial Secondary Tricuspid Regurgitation: Insights Into the EuroTR Registry.

JACC Cardiovasc Interv

December 2024

Medizinische Klinik und Poliklinik I, LMU Klinikum, LMU München, Munich, Germany; German Center for Cardiovascular Research, Partner Site Munich Heart Alliance, Munich, Germany. Electronic address:

Article Synopsis
  • Atrial secondary tricuspid regurgitation (A-STR) is a subtype of secondary tricuspid regurgitation (STR) that is often treated with transcatheter tricuspid valve edge-to-edge repair (T-TEER), showing distinct patient characteristics and treatment outcomes.
  • A study involving 641 patients revealed that 31% had A-STR, which was linked to better heart function, a higher presence of atrial fibrillation, and more effective TR reduction post-procedure compared to nonatrial STR patients.
  • A-STR patients experienced improved survival rates and lower symptomatic burdens after treatment; only 38% remained symptomatic (NYHA class ≥III) after 2 years, compared to 46

Transseptal Sheath Perfused with High Concentration Heparinized Saline for Reducing Sheath-associated Thrombus.

Pacing Clin Electrophysiol

December 2024

Department of Cardiology, Shanghai General Hospital, Shanghai Jiao Tong University, School of Medicine, Shanghai, China.

Article Synopsis
  • The study focused on the use of transseptal sheaths (TSS) for atrial fibrillation (AF) ablation, aiming to prevent thromboembolism through a simple saline flush management technique.
  • In the retrospective study involving over 4,700 AF patients, complications were low, with no acute strokes, and only a few thromboembolic issues occurring post-procedure.
  • The prospective study showed no thrombus formation in 127 procedures using high concentration heparinized saline, demonstrating that this method is both safe and effective for preventing thrombus during AF radiofrequency ablation.

Needle-free atrial transseptal access: A safe and reproducible alternative for left atrial catheterization.

Heart Rhythm O2

November 2024

Unidad Médica de Alta Especialidad en Pediatría, Centro Médico Nacional de Occidente, Instituto Mexicano del Seguro Social, Guadalajara, México.

Article Synopsis
  • Left atrial catheterization is a common procedure used to treat heart rhythm issues, but traditional methods involving needles can lead to complications; therefore, needle-free techniques are being investigated.
  • This study evaluates the safety and effectiveness of a new needle-free transseptal access (NeFTA) approach in three Mexican electrophysiology centers, using a guidewire and fluoroscopic guidance instead of a needle.
  • The NeFTA method was successful in 96.18% of cases, with very few complications (only 0.55% experienced pericardial effusion), indicating that it is a safe and reliable technique for accessing the left atrium.

Transcatheter tricuspid valve replacement (TTVR) has emerged as a promising intervention for the treatment of severe tricuspid regurgitation with complex valve morphology. This consensus document provides a comprehensive overview of the current state of orthotopic TTVR, focusing on patient selection, procedural details, and follow-up care. Clinical outcomes from initial studies and compassionate use cases are discussed, highlighting the effectiveness of TTVR in reducing tricuspid regurgitation, inducing reverse right ventricular remodeling, and enhancing patients' quality of life.

Background: Mitral annular calcification with valve dysfunction remains a challenging syndrome. Operative risk is high, and available transcatheter therapies are limited.

Methods: This study describes our initial experience with a novel procedure to address large mitral annuli when no surgical or trial-based transcatheter mitral valve replacement device is available.
