Efficacy of surgical ablation and left atrial appendage occlusion in patients with AF undergoing coronary artery bypass grafting: A network meta-analysis.
J Cardiol

Division of Cardiac Surgery, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.
Background: Atrial fibrillation (AF) is a prevalent cardiac arrhythmia that greatly elevates the risk of stroke. This risk increases both during and after cardiac procedures, such as coronary artery bypass grafting (CABG). There is an increasing interest in non-pharmacological treatments such as left atrial appendage occlusion (LAAO) and surgical ablation, intending to enhance both immediate and long-term postoperative results.

Objective: The use of an intra-aortic balloon pump (IABP) has been suggested to unload the left ventricle while on venoarterial extracorporeal membrane oxygenation (VA-ECMO) for cardiogenic shock (CS), leading to possibly improved in-hospital mortality. However, the predictors of mortality on dual mechanical circulatory support have not yet been evaluated, especially in real-world clinical settings. Therefore, a case-control study was conducted to determine the rate of all-cause mortality associated with VA-ECMO use regardless of left ventricular (LV) unloading, and with early LV unloading in the setting of CS, and to identify the predictors of mortality associated with VA-ECMO, with concurrent early LV unloading.

Right ventricular myocardial infarction (RVMI) is a significant and distinct form of acute myocardial infarction associated with considerable morbidity and mortality. It occurs most commonly due to proximal right coronary artery obstruction, often in conjunction with inferior myocardial infarction. RVMI poses unique diagnostic and therapeutic challenges due to the anatomical and functional differences between the right and left ventricles.

Background: This study aimed to investigate the major predictive factors associated with prolonged mechanical ventilation(PMV) following cardiac surgery.
Methods: This retrospective, cross-sectional, descriptive-analytical study was conducted from September 2021 to March 2022, involving 244 patients who underwent cardiac surgery. PMV was defined as mechanical ventilation for more than 24 h.
Hemodynamic analysis of left ventricular unloading with Impella versus IABP during VA-ECMO.

: The utilization of intra-aortic balloon pump (IABP) and Impella has been suggested as means of left ventricular unloading in veno-arterial extracorporeal membrane oxygenation (VA-ECMO) patients. This study aimed to assess the local hemodynamic alterations in VA-ECMO patients through simulation analyses. : In this study, a 0D-3D multiscale model was developed, wherein resistance conditions were employed to define the flow-pressure relationship.
