Sudden Unexpected Intrapartum Death and Left Ventricular Noncompaction involving the Right Ventricle Cardiovasc. Pathol. (IF 3.7) Pub Date : 2024-03-12 Giulia Ottaviani, Tobia Tomasello, Francesca Boggio, Letterio Runza, Alessandro Del Gobbo, L. Maximilian Buja
Left ventricular noncompaction (LVNC), involving mainly the right ventricle, is a rare form of congenital heart disorder characterized by a developmental arrest in myocardial compaction, resulting in a spongy appearance of the myocardium, mainly of the right ventricle, rarely detected in fetuses. We report the case of a female fetus with a gestational age of 41 weeks who came to our attention for intrapartum

The telocyte (TC) is a new interstitial cell type described in a wide variety of organs and loose connective tissues around small vessels, but its presence in large arteries remains unexplored. TCs have small cell bodies and remarkably thin, long, moniliform processes called telopods (Tps). Using transmission electron microscopy and immunofluorescence, we identified TCs in normal human thoracic aortas

Variations in subtle cystic tumors of the atrioventricular node: five autopsy cases Cardiovasc. Pathol. (IF 3.7) Pub Date : 2024-01-20 Hisanori Muramatsu, Kumiko Asakura, Tadashi Hosoya, Akira Kurosu
Cystic tumor of the atrioventricular node (CTAVN) is the most common primary cardiac tumor cause of sudden death but is rarely found during forensic autopsy. We present five autopsy cases of sudden death from undiagnosed CTAVN. The tumors varied in their histological appearance, which may be related to their variation in clinical presentation. Some of the cases had been diagnosed with epilepsy before

Lambl excrescences (LEs) were initially described in the mid-1800s during autopsies of human hearts, and their significance and biology have been debated ever since. LEs are typically found on aortic and pulmonary valve (semilunar) cusps. There is debate concerning whether LEs are a significant cause of thromboembolic events, or whether they are harmless growths. However, there have not been many reports

Mucopolysaccharidosis type II (MPSII) is a progressive lysosomal storage disease caused by mutations in the IDS gene, that leads to iduronate 2-sulfatase (IDS) enzyme deficiency. The enzyme catalyzes the first step of degradation of two glycosaminoglycans (GAGs), heparan sulfate (HS) and dermatan sulfate (DS). The consequences of MPSII are progressively harmful and can lead to death by cardiac failure

Giant cell arteritis (GCA) is the most common systemic vasculitis in adults in Europe and North America, typically involving the extra-cranial branches of the carotid arteries and the thoracic aorta. Despite advances in noninvasive imaging, temporal artery biopsy (TAB) remains the gold standard for establishing a GCA diagnosis.

Data from histopathology studies of human atherosclerotic tissue specimens and from vascular imaging studies support the concept that the local arterial microenvironment of a stable atheroma promotes destabilizing conditions that result in the transition to an unstable atheroma. Destabilization is characterized by several different plaque phenotypes that cause major clinical events such as acute coronary

The ongoing epidemic caused by the coronavirus SARS-CoV-2 is characterized by a variety of pathologic processes within the syndrome of COVID-19.

Characteristics of aortic and pulmonary valve cusp fenestrations in healthy hearts Cardiovasc. Pathol. (IF 3.7) Pub Date : 2023-06-30 Abhinav Goyal, Andrew J. Layman, Melanie C. Bois, Joseph J. Maleszewski
Fenestrations in semilunar valves of human hearts have been incidentally described during autopsies since the 1800s, and were thought to be a degenerative process of the valve cusps. Due to the nature of autopsy, prior literature has primarily examined these fenestrations in pathologic hearts, and has implicated them in leading to valve insufficiency, regurgitation, and cusp rupture.

Introduction Described for 60 years under various names, the carotid web is a suspected cause of cryptogenic stroke, especially in young patients. The web creates an intraluminal protrusion that may contribute to turbulent flow and thrombus embolization into cerebral arteries. Although the carotid web has frequently been related to arterial fibrodysplasia, its natural history and pathological description

Postmortem diagnosis of Takotsubo syndrome on autoptic findings: is it reliable? A systematic review Cardiovasc. Pathol.

Takotsubo syndrome (TTS) is a cardiac syndrome characterized by transient left ventricular systolic dysfunction in the absence of significant obstructive coronary artery disease. At the autopsy, its diagnosis is often challenging, since it is generally thought that it relates to no characteristic macroscopic or microscopic findings. In order to verify this last statement, we performed a systematic

Atrial inflammation and microvascular thrombogenicity are increased in deceased COVID-19 patients Cardiovasc. Pathol. (IF 3.7) Pub Date : 2023-01-14 Linghe Wu, Zhu Jiang, Eva R.

Background Histopathological studies have shown inflammation, cardiomyocyte injury, and microvascular thrombosis in the ventricular myocardium of patients with coronavirus disease 2019 (COVID-19). However, although atrial dysfunction is common in COVID-19, little is known about histopathological changes in the atria of the heart. We therefore analyzed inflammation, cardiomyocyte injury, and microvascular
