Published: May 2008

Persistent left superior vena cava (SVC) is an uncommon condition, usually encountered during cannulation of the left subclavian vein. We describe a patient who required a cardiac device upgrade to cardiac resynchronization implantable cardioverter defibrillator for biventricular failure. The presence of a persistent left SVC proved to be a blessing in disguise in this patient as he had since developed total occlusion of the left subclavian-innominate system.

Introduction And Objectives: Pulmonary vein (PV) isolation is one of the cornerstones of rhythm-control therapy for symptomatic atrial fibrillation (AF) patients. Pulsed field ablation (PFA) is a novel ablation modality that involves the application of electrical pulses causing cellular death, and it has preferential tissue specificity. In this study, we aimed to share a one-year single center experience of AF ablation with PFA.

A significant proportion of patients who have recovered from COVID-19 suffer from persistent symptoms, referred to as "post-acute sequelae of SARS-CoV-2 infection (PASC)". Abnormal brain intrinsic activity has been observed in PASC patients, but the patterns of frequency-dependent intrinsic activity in the PASC and non-PASC (recovered COVID-19 patients without persistent symptoms) groups and their association with neuropsychiatric sequelae remain unclear in PASC. Twenty-nine PASC patients, 27 non-PASC subjects, and 31 healthy controls (HCs) were recruited.

Concussions are a common form of mild traumatic brain injury characterized by a transient alteration of cerebral function leading to a range of physical, cognitive, and emotional symptoms. Postconcussive symptoms (PCSs) usually resolve in about a week but can persist in 10% to 15% of patients. If left untreated, PCS can profoundly affect a patient's life.

Atrial Cardiomyopathy: From Diagnosis to Treatment.

Department of Cardiology, Renmin Hospital of Wuhan University, 430060 Wuhan, Hubei, China.

With a better understanding of the susceptibility to atrial fibrillation (AF) and the thrombogenicity of the left atrium, the concept of atrial cardiomyopathy (ACM) has emerged. The conventional viewpoint holds that AF-associated hemodynamic disturbances and thrombus formation in the left atrial appendage are the primary causes of cardiogenic embolism events. However, substantial evidence suggests that the relationship between cardiogenic embolism and AF is not so absolute, and that ACM may be an important, underestimated contributor to cardiogenic embolism events.
