AI Article Synopsis
Article Abstract
A 48-year-old male visited the emergency room suffering from acute dysarthria and right hemiplegia. Brain magnetic resonance imaging (MRI) revealed multiple cerebral infarctions. Echocardiography showed a mass in the left atrium. He was diagnosed with cerebral embolism due to left atrial myxoma. Open heart surgery immediately after the attack is generally considered contraindicated because of such problems as hemorrhagic infarction or brain edema. However, relapse of embolism may make the condition worse and miss the timing of surgery. Eventually, we electively performed excision of the myxoma 20 days after the onset of cerebral infarction. The postoperative course was uneventful. This is a report about a rare case of open heart surgery shortly after the attack. The indication and the appropriate timing of open heart surgery following cerebral embolism were discussed.

An atrial septal defect (ASD) is a common congenital heart anomaly that results in irregular blood flow between the systemic and pulmonary circulations due to an opening in the atrial septum. Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.

Infectious myocarditis (IM) and infective endocarditis (IE), sometimes associated with infection of the surrounding mediastinal tissue or embolic complications caused by residual implantable cardioverter defibrillator (ICD) lead material embedded in the ventricle, present a significant challenge for cardiac surgeons due to the difficulty of precisely locating the old intracardiac pacing lead remnants because of the heart's continuous movement. We present the case of successful two-stage elective sternotomy extraction of two residual defibrillator leads, one trapped in the left innominate vein, easily removed after veinotomy without cardiopulmonary bypass (CPB), and the other embedded intramyocardially in the inferior wall of the right ventricle, successfully removed under CPB after fluoroscopic guidance. The patient was discharged four weeks post-operation without complications.

Background: Within the United States, White individuals experience a higher risk of atrial fibrillation (AF) while exhibiting a lower AF-related stroke risk compared to other ethnic groups. It is possible that these observations stem from phenomena unique to the United States, such as differential health care access. The United Kingdom provides socialized medicine, which ostensibly promotes equitable health care access.

Background: Cardiomyopathies are an important cause of heart failure in Africa yet there are limited data on etiology and clinical phenotypes.
Objectives: The IMHOTEP (African Cardiomyopathy and Myocarditis Registry Program) was designed to systematically collect data on individuals diagnosed with cardiomyopathy living in Africa.
Methods: In this multicenter pilot study, patients (age ≥13 years) were eligible for inclusion if they had a diagnosis of cardiomyopathy or myocarditis.

Atrial fibrillation (AF) is the most prevalent clinical arrhythmia, posing significant mortality and morbidity challenges. Outcomes of current catheter ablation treatment strategies are suboptimal, highlighting the need for innovative approaches. A major obstacle lies in the inability to comprehensively assess both structural and functional remodelling in AF.
