A 64-year-old woman presented for chest pain and was diagnosed with anteroseptal ST segment elevation myocardial infarction (STEMI). Emergent angiography showed 95% stenosis at the ostium of the second septal branch, consistent with thrombus, and no other significant lesions. The lesion was not amenable to intervention due to small caliber. Post angiography, the patient's electrical rhythm deteriorated into ventricular fibrillation. Following resuscitation, repeat angiography confirmed same findings. Electrophysiology study at 3 months was positive for inducing fibrillation. Due to patient risk factors, she had placement of a dual chamber defibrillator. A 5-month follow-up echocardiogram showed a small area of ventricular septal wall bowing, consistent with blood supply from septal territory.

Atrial fibrillation (AF) has emerged as a major global cardiovascular disease in the 21st century. In China, there are greater than 12 million patients with AF, and its incidence continues to rise. AF affects patients' quality of life and significantly increases the risks of mortality, stroke, heart failure, cognitive impairment, and dementia.

Background: Newborns with transposition of the great arteries (TGA) are at risk of severe hypoxia from inadequate atrial mixing, closure of the arterial duct and/or pulmonary hypertension (PPHN). Acute maternal hyperoxygenation (AMH) might assist in identifying at-risk fetuses. We report pulmonary vasoreactivity to AMH in TGA fetuses and its relationship to early postnatal hypoxia and requirement for emergency balloon atrial septostomy (e-BAS).

Objective: The aim of the study was to assess the feasibility and efficacy of intraprocedural transthoracic echo guidance to achieve LBB capture.

Absence of the ductus arteriosus (DA) is common in tetralogy of Fallot (TOF), occurring in up to 30% of cases. Yet, the clinical course and fetal echocardiographic features are not well described, limiting prenatal counseling. This study examines the fetal echocardiographic characteristics and perinatal outcomes in children with TOF absent DA (TOF/ADA), comparing them to those with a DA (TOF/DA).
