Twenty patients with hypertrophic cardiomyopathy were examined. They were found to have late ventricular potentials in the disease, which were characterized by an increase in average QRS complex duration, a decrease in voltage, and a rise in the duration of last 40 msec of the QRS complex filtered. Such patients generally exhibited lower exercise tolerance in severe asymmetric left ventricular hypertrophy, which caused a significant deterioration of cardiac pump function.

Differential diagnosis of thrombosis and myxoma in unusual heart positions by dual-energy CT multiple parameter imaging: A case series.

Department of Medical Imaging, Jincheng People's Hospital, Shanxi, China.
Rationale: Thrombus is the most common occupying lesion in the cardiac chambers, it is often distinguished from cardiac neoplastic occupations. Among them, the most common is cardiac myxoma, whose imaging manifestations are often confused with thrombus. However, the 2 types of lesions have different therapeutic strategies and are both potentially high-risk sources of embolism, so early differentiation between intracardiac thrombus and cardiac tumor is essential.

Congenital heart disease (CHD) represents a major birth defect associated with substantial morbidity and mortality. Although environmental factors are acknowledged as potential contributors to CHD, the underlying mechanisms remain poorly understood. Bisphenol A (BPA), a common endocrine disruptor, has attracted significant attention due to its widespread use and associated health risks.

Cardiology Department, Unidade Local de Saúde do Alto Ave, Guimarães, Portugal.
Purpose: This study explores the effects of anthracycline chemotherapy (AC) on breast cancer patients, focusing on changes in body composition, advanced echocardiographic parameters at rest and during exercise, and biomarkers; and subsequently assesses whether these parameters are associated with impaired cardiorespiratory fitness (CRF).
Methods: In this prospective study, we evaluated women with early-stage breast cancer undergoing AC at three visits: before AC, 1 month after, and 6 months post-AC.
Results: The study included 32 women with breast cancer, with functional disability increasing from 9.
Extracorporeal membrane therapy in a case of ruptured abscess on the mitroaortic intervalvular fibrosa associated to multisystem inflammatory syndrome: a case report.
Egypt Heart J

Intensivista Pediátrico, Fundación Clínica Infantil Club Noel, Cali, Colombia.
Background: The mitroaortic intervalvular fibrosa is an avascular structure near the left ventricular outflow tract, between the mitral and aortic valves. Mitroaortic intervalvular fibrosa complications, such as tamponade, hemopericardium, and abscesses, are rare and often diagnosed postmortem. On the other hand, the COVID-19 pandemic notably impacted pediatric patients with congenital heart diseases, who frequently presented cardiac complications including arrhythmias, elevated troponins, myocarditis, and heart failure.

Purpose Of The Review: Takotsubo syndrome (TTS) is a transient form of left ventricular dysfunction, typically affecting post-menopausal females, often preceded by emotional or physical stressful events that act as triggers. Initially believed to be a rare and benign condition for its reversible nature, TTS has recently emerged as a complex multifaceted clinical entity, with heterogenous clinical presentations and a non-negligible risk of serious in-hospital complications, including acute heart failure, arrhythmias and death.
Recent Findings: Emerging pathophysiological hypotheses, ranging from microvascular dysfunction to systemic inflammation, offer new insights into the underlying mechanisms of TTS.
