AI Article Synopsis

  • In patients with a mechanical tricuspid prosthetic valve, using a ventricular lead through the coronary sinus (CS) is a viable alternative to traditional lead placements.
  • The optimal position for the CS lead during cardiac resynchronization therapy is still debated, especially for patients without a left bundle branch block.
  • A reported case showed successful placement of a CS lead in the anterior interventricular vein, resulting in low pacing thresholds and a left ventricular ejection fraction of 58.9% after 2 years.

Article Abstract

In patients with a mechanical tricuspid prosthetic valve, the transvenous position of a ventricular lead through the coronary sinus (CS) is a good alternative option to right ventricular or epicardial lead implantation. In cardiac resynchronization therapy, pacing the left ventricular lateral wall was considered the best site for the CS lead. However, for patients without a left bundle branch block, the best position of CS leads remains controversial. Here, we present a case of placing CS lead in the anterior interventricular vein. Measurements at implantation and 2 years' follow-up reported low pacing thresholds with good sensing thresholds. The electrocardiograph showed narrow QRS complexes (120 ms) and follow-up echocardiography at 2 years presented left ventricular ejection fraction 58.9%.

The study was designed to investigate the pattern of intraventricular Hemo-Dynamic Forces (HDF) and myocardial performance during exercise in Elite Cyclists (EC). Transthoracic stress echocardiography was performed on nineteen EC and thirteen age-matched sedentary controls (SC) at three incremental exercise intensities based on Heart Rate Reserve (HRR). Left Ventricular (LV) HDF were computed from echocardiography long-axis data sets using a novel technique based on endocardial boundary tracking, both in apex-base and latero-septal directions.

The authors propose a modified transcatheter aortic valve replacement technique wherein the removal of the guidewire and delivery catheter immediately after the valve implantation helps to not only shorten the procedure but also decrease complications induced by the guidewire and delivery catheter.

Outcomes of a transapical edge-to-edge repair system in secondary mitral regurgitation.

J Invasive Cardiol

Department of Cardiology, Zhongshan Hospital, Fudan University, Shanghai Institute of Cardiovascular Diseases, China; State Key Laboratory of Cardiovascular Diseases, Zhongshan Hospital, Fudan University; NHC Key Laboratory of Ischemic Heart Diseases; Key Laboratory of Viral Heart Diseases, Chinese Academy of Medical Sciences; National Clinical Research Center for Interventional Medicine, Shanghai, China.

Objectives: The ValveClamp system (Hanyu Medical Technology) is a novel transcatheter edge-to-edge repair (TEER) system designed for ease of operation; however, there is a lack of data on its application in secondary mitral regurgitation (SMR). The authors report the mid-term outcomes of TEER using the ValveClamp system in SMR.

Methods: The study prospectively analyzed consecutive severe SMR patients who underwent transapical ValveClamp implantation at 10 Chinese centers.

Blood Pressure Control and Incident Left-Ventricular Conduction Disease.

Curr Cardiol Rep

Division of Cardiology, Department of Medicine, University of California San Francisco, 505 Parnassus Ave, M1180B, San Francisco, CA, 94143, USA.

Purpose Of Review: Cardiac conduction disease, a harbinger of pacemaker implantation, heart failure, and death, is commonly regarded as immutable. However, emerging research suggests it may be a target for upstream prevention strategies such as blood pressure management. This review summarizes recent evidence regarding blood pressure control and the development of conduction disease.

Extracellular vesicle-mediated VEGF-A mRNA delivery rescues ischaemic injury with low immunogenicity.

Eur Heart J

January 2025

School of Chemical Biology and Biotechnology, Peking University Shenzhen Graduate School, Shenzhen, 2199 Lishui Rd, Nanshan, Shenzhen, Guangdong Province 518055, China.

Background And Aims: Lackluster results from recently completed gene therapy clinical trials of VEGF-A delivered by viral vectors have heightened the need to develop alternative delivery strategies. This study aims to demonstrate the pre-clinical efficacy and safety of extracellular vesicles (EVs) loaded with VEGF-A mRNA for the treatment of ischaemic vascular disease.

Methods: After encapsulation of full-length VEGF-A mRNA into fibroblast-derived EVs via cellular nanoporation (CNP), collected VEGF-A EVs were delivered into mouse models of ischaemic injury.
