AI Article Synopsis

  • Primary cardiac tumors are rare, with myxomas being the most common benign type.
  • A female patient in her 50s underwent surgery to remove a myxoma, during which complications arose including damage to the aorta-mitral valve area and severe mitral regurgitation, leading to additional surgeries.
  • Post-surgery, the patient faced several serious issues like atrial fibrillation, heart failure, and a transient ischemic attack, highlighting the importance of monitoring for complications after the procedure.

Article Abstract

Primary cardiac tumors are a rare occurrence with myxomas accounting for about half of the benign tumors. Once diagnosed, surgical resection is the standard of care. Our case describes a female in her 50s who underwent a myxoma resection under cardiopulmonary bypass via biatrial approach. Intraoperatively, the thin septal crux between the wall of the aorta and mitral valve was damaged during resection, requiring stem cell tissue matrix for repair. The patient also developed severe mitral regurgitation suggesting infarct to the left coronary system during resection, subsequently receiving a mechanical mitral valve and a saphenous vein bypass graft. Postoperatively, she developed atrial fibrillation with a left atrial appendage thrombus, heart failure with an ejection fraction of 30%-35%, and a transient ischemic attack. In conclusion, it is important for the clinician to appreciate the possible complications of resection peri and postoperatively.

Purpose Of Review: This review aims to explore the complex interplay between atrial functional mitral regurgitation (AFMR), atrial fibrillation (AF), and heart failure with preserved ejection fraction (HFpEF). The goal is to define these conditions, examine their underlying mechanisms, and discuss treatment perspectives, particularly addressing diagnostic challenges.

Recent Findings: Recent research highlights the rising prevalence of AFMR, now accounting for nearly one-third of significant mitral regurgitation cases.

Introduction: A hybrid approach with very high-power short-duration (vHPSD) posteriorly and ablation-index guided HPSD (50 W) anteriorly seems to be an optimal balance between efficiency and effectiveness for point-by-point pulmonary vein isolation (PVI). The aim of the current study is to compare vHPSD/HPSD ablation to cryoballoon ablation (CBA) in patients with symptomatic atrial fibrillation (AF).

Methods And Results: In this retrospective single-center study, we identified 110 consecutive patients who underwent their first PVI with either vHPSD/HPSD (n = 54) or CBA (n = 56).

Surgical and Ablation Therapies for Atrial Appendage Tachycardia in Children.

JACC Clin Electrophysiol

December 2024

Department of Pediatric Cardiology, Heart Center, First Hospital of Tsinghua University (Beijing Huaxin Hospital), Chaoyang District, Beijing, China.

Background: Atrial tachycardia (AT) originate from the atrial appendage present unique clinical challenges in pediatrics. It is typically persistent, frequently leading to tachycardiomyopathy, and poses significant treatment difficulties.

Objectives: This study aimed to collate and analyze the clinical characteristics and therapeutic outcomes of radiofrequency ablation (RFCA) and with atrial appendage resection for the treatment of AT originating from the atrial appendages in pediatric patients.

Left atrial appendage occlusion (LAAO) has become an important therapeutic target for stroke prevention in patients with nonvalvular atrial fibrillation. Over the past 2 decades, several advancements in LAAO devices (percutaneous and surgical) have been made for stroke prevention and arrhythmia therapy. However, there are several unanswered questions regarding optimal patient selection, the preferred LAAO approach and device, the management of periprocedural and postprocedural complications, including pericardial effusion, device-related thrombus, and device leaks.

Subclavian Ansae Stimulation on Cardiac Hemodynamics and Electrophysiology in Atrial Fibrillation: A Target for Sympathetic Neuromodulation.

JACC Clin Electrophysiol

December 2024

St Bartholomew's Hospital, Barts Health NHS Trust, London, United Kingdom; William Harvey Research Institute, Queen Mary University of London, London, United Kingdom. Electronic address:

Background: The sympathetic autonomic nervous system plays a major role in arrhythmia development and maintenance. Historical preclinical studies describe preferential increases in cardiac sympathetic tone upon selective stimulation of the subclavian ansae (SA), a nerve cord encircling the subclavian artery.

Objectives: This study sought to define, for the first time, the functional anatomy and physiology of the SA in humans using a percutaneous approach.
