Transcatheter closure of paravalvular leakage through multiple approaches after surgical mechanical valve replacements: A retrospective study.
Medicine (Baltimore)
November 2024
Department of Cardiovascular Surgery, Xijing Hospital, Air Force Medical University, Xi'an, Shaanxi Province, China.
Background: Transcatheter closure of percutaneous paravalvular leak (PVL) is a technically challenging procedure, especially after surgical mechanical valve replacements (SMVR), as the risk of interference with the prosthetic valve discs and the complex interventional techniques required for mitral PVL closure. Our study was designed to review the results with transcatheter closure of PVL after SMVR.
Methods: From January 2018 through December 2023, a total of 64 patients with PVL after SMVR underwent transcatheter closure with the help of preoperative 3-dimensional printing model and simulator for image evaluation.
Radiation exposure during cardiac interventions in CHD: German Registry 2012-2020.
Thorac Cardiovasc Surg
January 2025
Pediatric Cardiology, University Hospital Tuebingen, Tubingen, Germany.
Background: Since patients with congenital heart defects (CHD) frequently require life-long medical care and repeat invasive treatment, radiation exposure during interventional procedures is a relevant issue concerning potential radiation related risks. Therefore, an analysis on radiation data from the German Registry for Cardiac Operations and Interventions in patients with CHD was performed.
Methods: From January 2012 until December 2020 a total of 28,374 cardiac catheter interventions were recorded.
Percutaneous left atrial appendage closure using a modified single-operator-technician approach under deep sedation: A single-center experience.
Heart Rhythm O2
December 2024
Department of Electrophysiology, North Mississippi Medical Center, Tupelo, Mississippi.
Background: Historically, percutaneous transcatheter left atrial appendage closure (LAAC) has been performed under general anesthesia (GA) with transesophageal echocardiographic images obtained by a noninvasive cardiologist and usually requires an overnight hospital stay. Alternatively, we present our single-center experience performing LAACs under deep sedation (DS), employing an echocardiographic technician instead of a noninvasive cardiologist, and expediting same-day discharge. Mid- to long-term outcomes were also evaluated with follow-up imaging at a 45-day visit.

Preliminary exploration of metabolomics mechanisms in patients with patent foramen ovale and migraine.

Department of Cardiology, Xinjiang Medical University Affiliated Traditional Chinese Medicine Hospital, 830001 Urumqi, Xinjiang Uyghur Autonomous Region, China.
This study aimed to investigate the metabolic mechanisms underlying the combination of patent foramen ovale (PFO) and migraine by assessing metabolite expression before and after interventional occlusion surgery. The study included 11 PFO patients from the Heart Center of Xinjiang Medical University Affiliated Hospital of Traditional Chinese Medicine, who underwent transcatheter PFO intervention and occlusion surgery between January 2018 and February 2023, and 11 healthy controls. Blood samples were collected pre-surgery, 3 days post-surgery, and 30 days post-surgery for metabolomics analysis.
