Usefulness of Artificial Pneumothorax during Totally Endoscopic Off-Pump Left Atrial Appendage Closure and Surgical Ablation.
Ann Thorac Cardiovasc Surg
January 2025
Department of Cardiovascular Surgery, Kobe University, Kobe, Hyogo, Japan.
Purpose: In totally endoscopic off-pump left atrial appendage (LAA) closure and surgical ablation, securing the operative field is sometimes difficult in some patients because of a narrow working space caused by an elevated diaphragm or ventricles. In this study, we aimed to investigate the effectiveness of a method that facilitates securing the operative field using an artificial pneumothorax.
Methods: We analyzed 71 consecutive patients who underwent totally endoscopic off-pump LAA closure and bilateral pulmonary vein isolation.
Risk factors analysis and nomogram model construction for postoperative atrial fibrillation after off-pump coronary artery bypass grafting.
Pak J Med Sci
January 2025
Zhuqing Ji Department of Medicine Oncology, The Affiliated Huai'an 1st People's Hospital of Nanjing Medical University, Huaian, Jiangsu Province 223300, P.R. China.
Objective: To explore the risk factors associated with postoperative atrial fibrillation (POAF) after off-pump coronary artery bypass grafting (OPCABG) and to construct a nomogram predictive model.
Methods: In this retrospective cohort study, clinical data of 193 patients who received OPCABG in Huai'an First People's Hospital Affiliated to Nanjing Medical University from June 2021 to November 2023 were retrospectively analyzed. Based on the established diagnosis of POAF, patients were divided into the POAF group (n=75) and the non-POAF group (n=118).
Normothermic Crystalloid Polarizing Cardioplegia Improves Systolic and Diastolic Function in a Porcine Model of Cardiopulmonary Bypass.

Ludwig Boltzmann Institute for Cardiovascular Research, Center for Biomedical Research and Translational Surgery, Medical University of Vienna, 1090 Vienna, Austria.
Previously, we showed that blood-based polarizing cardioplegia exerted beneficial cardioprotection during hypothermic ischemia; however, these positive effects of blood-based polarizing cardioplegia were reduced during normothermic ischemia compared to blood-based hyperkalemic (depolarizing) cardioplegia. This study compares crystalloid polarizing cardioplegia to crystalloid depolarizing cardioplegia in a normothermic porcine model of cardiopulmonary bypass; Methods: Twelve pigs were randomized to receive either normothermic polarizing ( = 7) or depolarizing ( = 5) crystalloid cardioplegia. After the initiation of cardiopulmonary bypass, normothermic arrest (34 °C, 60 min) was followed by 60 min of on-pump and 90 min of off-pump reperfusion.

J Cardiovasc Dev Dis
January 2025
Department of Cardiac Surgery, Lankenau Heart Institute, Main Line Health, Wynnewood, PA 19096, USA.
Objectives: The impact of long-term complications after robotic hybrid coronary revascularization (HCR), including persistent angina, repeat revascularization, and myocardial infarction (MI), remains limited. This study aims to determine the risk factors for coronary events after robotic HCR and their time-varying effects on outcomes.
Methods: We identified all consecutive patients who underwent robotic HCR at our institution.
A surgical case of right ventricular outpouching.
J Cardiol Cases
January 2025
Department of Cardiology, Hokko Memorial Hospital, Sapporo, Japan.
Unlabelled: Outpouching of the heart ventricles, especially of the right ventricle, is rare. Here, we report the case of a 60-year-old male, referred to our institution with an outpouched structure at the right ventricular apex. The patient had no cardiac events.
