Iatrogenic diversion of inferior vena cava to the left atrium presented as persistent hypoxemia: Case series.
Medicine (Baltimore)
January 2025
Department of Center for Pulmonary Vascular Disease, Fuwai Hospital, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.
Rationale: The transcatheter closure and atrioseptopexy are the main treatment methods for atrial septal defect (ASD). However, persistent hypoxemia due to iatrogenic diversion of inferior vena cava (IVC) to the left atrium (LA) is reported as a rare complication after ASD closure. Contrast echocardiology is a reliable and powerful tool to detect iatrogenic diversion and identify the etiology accurately.

Background: The role of a prothrombotic state in atrial fibrillation (AF) progression to permanent arrythmia (PerAF) is unclear. Formation of denser and poorly lysable fibrin clots has been observed in AF patients also with sinus rhythm in association with higher stroke risk. We investigated whether altered fibrin clot properties and other prothrombotic state markers may contribute to AF transition to PerAF.

Department of Health Care Policy, Harvard Medical School, Boston, MA.
Background And Objectives: Early presentation and acute treatment for patients presenting with ischemic stroke are associated with improved outcomes. The onset of the COVID-19 pandemic was associated with a large decrease in patients presenting with ischemic stroke, but it is unknown whether these changes persisted.
Methods: This study analyzed emergency department (ED) stroke presentations (n = 158,060) to all nonfederal hospitals in the 50 states and Washington, D.
Ablation of slow activation areas in addition to pulmonary vein isolation improves the maintenance of the sinus rhythm in patients with persistent atrial fibrillation.

Department of Cardiology, Second Affiliated Hospital of Zhejiang University School of Medicine, 88 Jiefang Road, Hangzhou, 310009, Zhejiang, China.
Background: Slow activation areas, characterized by decreased conduction velocities in the left atrium, are commonly observed in patients with persistent atrial fibrillation (PeAF). However, it remains unclear whether the ablation of slow activation areas combined with pulmonary vein isolation (PVI) improves clinical outcomes in these patients.
Methods: This single-center retrospective study included patients who underwent catheter ablation for PeAF.
Echocardiography evaluation of iatrogenic atrial septal defect after combined procedure of catheter ablation and left atrial appendage closure for atrial fibrillation.

Using transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) to investigate the occurrence and related causes of iatrogenic atrial septal defect (iASD) after catheter ablation combined with left atrial appendage closure (LAAC) for atrial fibrillation (AF) and its impact on the right heart system. We retrospectively analyzed 330 patients that underwent combined procedure of catheter ablation for AF and LAAC at General Hospital of Northern Theater Command from January 2018 to March 2022. These patients were divided into iASD group and non-iASD group according to whether there was persistent iASD shown on TEE at 3 months after procedure.
