A new insight into the anatomical ablation approach at R-L ILT for VAs with a left ventricular summit origination: electrophysiological characteristics and catheter ablation.
J Interv Card Electrophysiol
January 2025
Department of Cardiology, Shanghai Institute of Cardiovascular Diseases, Zhongshan Hospital, Fudan University, No.180, Feng-Lin Road, Shanghai, 200032, P.R. China.
Background: Ventricular arrhythmia (VA) originating from the left ventricular summit (LVS) poses particular challenges, with higher rates of ablation failure.
Objective: To further evaluate the anatomical ablation approach from the subaortic region for LVS VAs and their electrophysiological characteristics.
Method: The study enrolled 27 consecutive patients with sympatomatic VAs originating from LVS and who received an anatomical ablation approach from R-L ILT in our center.
Comparing surgical techniques and results of secondary ischemic mitral regurgitation: a state-of-the-art literature review.
Ann Transl Med

Department of Cardiac Surgery, Centre Cardiologique du Nord, Saint-Denis, France.
Background And Objective: Surgery for mitral valve disease is a developing area with a wide range of surgical options. There is growing evidence on the best approach for secondary ischemic mitral regurgitation (SIMR) when the pathology is within the ventricle. The goal of this literature review is to provide a comprehensive comparison of surgical treatments for SIMR.

Article Synopsis
- * Researchers identified LVOTO events through echocardiography and observed that 13.7% of patients who had a primary aortoplasty developed LVOTO, with higher rates in those with certain conditions like a bicuspid valve or subaortic ridge.
- * The findings suggest that having multiple risk factors significantly increases the likelihood of needing further surgical intervention for LVOTO in patients with IAA/CoA.
Idiopathic ventricular arrhythmia originating from the vicinity of lateral tricuspid annulus: The precise origin and anatomic concerns.
Heart Rhythm
July 2024
Department of Cardiology, Beijing Anzhen Hospital, Capital Medical University, National Clinical Research Center for Cardiovascular Diseases, Beijing, China.
Background: Although the electrocardiographic and electrophysiological properties of ventricular arrhythmias (VAs) from the vicinity of the lateral tricuspid annulus (TA) have been reported in previous studies, their precise site of origin have not been addressed.
Objective: The purpose of this study was to describe the precise origin of lateral TA-VA and the relevant anatomy.
Methods: Consecutive patients with idiopathic lateral TA-VAs were reviewed and analyzed.
Retrograde coronary venous ethanol ablation for ventricular tachycardia in a patient with inaccessible substrate due to previous surgery.

Cardiovascular Division, Department of Medicine, Vanderbilt University Medical Center, Nashville, Tennessee, USA.
Introduction: Catheter-based radiofrequency (RF) ablation is generally regarded as the standard approach for patients with ventricular tachycardia (VT) refractory to antiarrhythmic drug therapy and may be considered as a first-line approach when there is a preference to avoid these agents. Patients with a history of cardiac surgery may have VT substrate inaccessible to catheter ablation due to intervening prosthetic materials or scar.
Methods And Results: This article describes a 55-year-old patient with a history of surgically repaired subvalvular aortic stenosis and subsequent valve-sparing root replacement who presented with sustained VT.
