AI Article Synopsis
- Surgical closure used to be the only treatment for atrial septal defects (ASD), but device placement is now preferred.
- A study compared left ventricular diastolic function between patients who had surgical vs. device closure, finding significant differences at least one year post-procedure.
- Results indicated that surgical closure had a greater impact on diastolic function compared to device closure, particularly in late diastolic velocities.
Article Abstract
While surgical closure used to be the only treatment for atrial septal defects (ASD), recently, placement of an occluding device has become the treatment of choice for this condition. We sought to study the remote effects of surgical vs. device ASD closure on the indices of left ventricular diastolic function. Forty patients--16 after device and 19 after surgical closure--were evaluated at least 1 year after the procedure. Mitral inflow and tissue Doppler indices were studied. The results were compared to those of 65 control subjects. The early mitral inflow velocities E were higher in controls and E/A ratios were different among all 3 groups. Late diastolic A' TDI velocities were higher in both device and surgical group patients and more different from the controls in surgical than in device group. It appears that surgical ASD closure alters left ventricular diastolic indices more significantly than device ASD closure.

Background: The Fontan procedure is a surgical intervention designed for patients with single ventricle physiology, wherein the systemic venous return is redirected into the pulmonary circulation, thereby facilitating passive pulmonary blood flow without the assistance of ventricular propulsion. Consequently, long-term follow-up of individuals who have undergone the asymptomatic Fontan procedure is essential.
Objectives: The aims of this investigation were to: 1) examine the impact of flow components and kinetic energy (KE) parameters on hemodynamic disturbances in asymptomatic Fontan patients and control group; 2) Assess left ventricular diastolic dysfunction through the analysis of 4D flow parameters across different Fontan sub-groups; 3) Compare intracardiac flow parameters among Fontan sub-groups based on morphological features of the left ventricle (LV) and right ventricle (RV).
Epicardial fat tissue, a hidden enemy against the early recovery of left ventricular systolic function after transcatheter aortic valve implantation.

Department of Cardiology, Leiden University Medical Center, Leiden, the Netherlands.
Background: Epicardial fat tissue (EFT) is an active organ that can affect cardiac function and structure through endocrine, paracrine, and proinflammatory mechanisms. We hypothesized that greater thickness of EFT may harm the recovery of left ventricular (LV) systolic function in patients with severe aortic stenosis (AS) and reduced LV ejection fraction (EF ≤ 50 %) undergoing transcatheter aortic valve implantation (TAVI).
Methods: A sixty six patients with severe AS and 20 % ≥ LVEF ≤ 50 % who underwent TAVI were included.

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).
