Pulmonary valve endocarditis caused by right ventricular outflow obstruction in association with sinus of valsalva aneurysm: a case report

Journal of Cardiothoracic Surgery, 2008
Background Right-sided infective endocarditis is uncommon. This is primarily seen in patients with intravenous drug use, pacemaker or central venous lines, or congenital heart disease. The vast majority of cases involve the tricuspid valve.

Pimobendan alleviates myocyte apoptosis and fibrosis associated with mitral regurgitation by targeting endoplasmic reticulum stress

Animal Models and Experimental Medicine, EarlyView.
Mitral regurgitation (MR) causes volume overload and disrupts Ca2+ homeostasis. The volume overload leads to cardiac hypertrophy and fibrosis inferred from histopathological studies. Cardiac hypertrophy was identified by increased myocyte cross‐sectional area, left atrial‐to‐aortic root ratio, and left ventricular internal diameter at end‐diastole ...

Discovery of sexual dimorphism of the laryngeal sac in the common minke whale Balaenoptera acutorostrata

The Anatomical Record, EarlyView.
Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Antiphospholipid Syndrome: An Antibody‐Mediated Disease With Emerging Therapeutic Opportunities

Arthritis &Rheumatology, EarlyView.
Antiphospholipid syndrome (APS) is an autoimmune thromboinflammatory disease characterized by vascular thrombosis, pregnancy morbidity, and other manifestations driven by antiphospholipid autoantibodies. In this review, we present a clinical case that illustrates some diagnostic and therapeutic challenges in managing severe, relapsing APS ...

Surgical strategies protecting against right ventricular dilatation following tetralogy of Fallot repair

Journal of Cardiothoracic Surgery, 2018
Background Right ventricular (RV) volume overload increases morbidity and mortality after tetralogy of Fallot (TOF) repair. Surgical strategies like pulmonary leaflets sparing and tricuspid valve repair at time of primary repair may decrease RV overload.

A Meta‐Analysis and Simplified Nomenclature for Diagonal Coronary Artery and Ramus Intermedius Across Adult and Pediatric Hearts

Clinical Anatomy, EarlyView.
ABSTRACT Anatomical descriptions of left‐sided oblique coronary branches remain inconsistent, hindering imaging interpretation and surgical planning. To quantify the prevalence, branching patterns and morphometry of the ramus intermedius (RI) and diagonal branches, and propose a unified nomenclature.

Pulmonary Valve Replacement Using an Intraoperatively Created Trileaflet Autologous Pericardial Valve: A Case Series [PDF]

Iranian Journal of Medical Sciences
Background: Pulmonary valve replacement is inevitable for the majority of patients with long-standing pulmonary regurgitation. The purpose of this study was to describe the experience of employing a novel technique to create an intraoperatively handmade ...
