Cerebral Embolism and MINOCA Secondary to Left Atrial Myxoma after Occlusion of Atrial Septal Defect by Amplatzer Occluder: A Case Report.

Primary heart tumors are rare, with atrial myxomas being the most common type. Atrial myxomas can lead to embolisms, heart obstruction, and systemic symptoms. Herein, we report a case of 72-year-old woman who presented with a left atrial myxoma at the atrial septal defect occluder, a new acute cerebral infarction, and MINOCA (myocardial infarction with no obstructive coronary atherosclerosis).

Application of remote electrocardiogram monitoring systems in chest pain centers for patients with high-risk chest pain.

Background: Chinese chest pain centers (CPCs) have been expanding and maturing for the past decade, but patient wait times for pre-hospital care remain long.

Objective: To demonstrate that the remote electrocardiogram (ECG) monitoring system can ensure more efficient treatment for patients with ST-elevation myocardial infarction (STEMI) in CPCs, we compared patients with high-risk chest pain who used remote ECG monitoring systems to those who used conventional ECGs in retrospective cohort study.

Methods: Based on the inclusion and exclusion criteria, 290 patients who visited our CPC between June 2019 and March 2022 with acute chest pain and a diagnosis of STEMI as well as patients who had undergone an emergency primary percutaneous coronary intervention were selected.

Transcatheter closure of doubly committed subarterial ventricular septal defects with the Amplatzer ductal occluder: initial experience.

Background: There is limited experience about transcatheter closure of doubly committed subarterial ventricular septal defects with Amplatzer ductal occluder.

Methods: Between March, 2015 and July, 2017, a total of 22 patients with doubly committed subarterial ventricular septal defects received transcatheter closure using Amplatzer ductal occluder and underwent clinical follow-up for at least 6 months.

Results: Device implantation was finally successful in 21 (95.

Effectiveness of Percutaneous Balloon Mitral Valvuloplasty for Rheumatic Mitral Stenosis with Mild to Severe Mitral Regurgitation.

This study is designed to test whether percutaneous balloon mitral valvuloplasty (PBMV) is effective for rheumatic mitral stenosis in Chinese patients with moderate to severe mitral regurgitation. Fifty-six patients with rheumatic mitral valve stenosis were divided into the mild, moderate, and severe regurgitation groups. Cardiac ultrasonography was measured before and 1 to 2 days after PBMV.

TLR1 expression in mouse brain was increased in a KA-induced seizure model.

Objective: Toll-like receptors (TLRs) that mediate inflammatory responses play an important role in epilepsy; however, whether TLR1 is also involved in epileptogenesis remains unclear. Thus, in this study, we investigated the extent and pattern of TLR1 expression in epileptic tissues.

Methods: One-hundred and thirty-two mice were intra-cerebroventricularly injected with PBS or kainic acid (KA) and were examined at 1, 3, 8 and 24 h.

Application of percutaneous balloon mitral valvuloplasty in patients of rheumatic heart disease mitral stenosis combined with tricuspid regurgitation.

Background: Tricuspid regurgitation (TR) is frequently associated with severe mitral stenosis (MS), the importance of significant TR was often neglected. However, TR influences the outcome of patients. The aim of this study was to investigate the efficacy and safety of percutaneous balloon mitral valvuloplasty (PBMV) procedure in rheumatic heart disease patients with mitral valve (MV) stenosis and tricuspid valve regurgitation.

[Percutaneous coronary intervention of patients with complex small coronary artery lesion unsuitable for coronary artery bypass graft].

Objective: To investigate the safety and efficacy of percutaneous coronary intervention (PCI) in patients with low left ventricular ejection fraction (LVEF) and complex small coronary artery lesions.

Methods: Complete or partial post-PCI revascularization of coronary artery was employed in 16 patients with a low LVEF and complex small coronary artery lesions who were unsuitable for CABG (coronary artery bypass grafting). All cases were observed with regards to immediate success rate of operation, complication, hospitalization duration, improvement of cardiac function and LVEF and major adverse cardiac events (including cardiac death, myocardial infarction and target lesion revascularization) at 12 months post-operation.
