Epstein-Barr virus (EBV) associated smooth muscle tumors (SMTs) have been described in patients with acquired immune deficiency syndrome (AIDS) and, more recently, in association with immunosuppression after solid-organ transplantation. We present the autopsy findings of multiple leiomyosarcomas (LMSs) in a 24-year old man who died 18 months after undergoing orthotopic cardiac transplantation for idiopathic cardiomyopathy. The recognition of EBV-driven LMS developing in cardiac transplant recipients in multiple unusual sites is crucial for the management of these patients and should include complete surgical removal anti-viral therapy and modulation of immunosuppression.

Background: Neutrophil-to-lymphocyte ratio (NLR) is an easy-to-use inflammatory biomarker. Baseline NLR is independently associated with incident cardiovascular events and all-cause mortality. However, whether this applies to acute myocarditis (AM) has not been evaluated.

Intraoperative hemodynamic monitoring is crucial for managing patients with end-stage liver disease (ESLD) undergoing orthotopic liver transplantation (OLT) due to their complex cardiovascular and pulmonary abnormalities. Traditionally, pulmonary artery catheterization (PAC) has been the standard for hemodynamic monitoring during OLT. However, the use of transesophageal echocardiography (TEE) has increased due to its real-time visualization of cardiac and vascular structures, which aids in managing hemodynamic instability during the three surgical phases of OLT: pre-anhepatic, anhepatic, and neo-hepatic.

Background: The decrease in S-nitrosoglutathione reductase (GSNOR) leads to an elevation of S-nitrosylation, thereby exacerbating the progression of cardiomyopathy in response to hemodynamic stress. However, the mechanisms under GSNOR decrease remain unclear. Here, we identify NEDD4 (neuronal precursor cell expressed developmentally downregulated 4) as a novel molecule that plays a crucial role in the pathogenesis of pressure overload-induced cardiac hypertrophy, by modulating GSNOR levels, thereby demonstrating significant therapeutic potential.

Background: Exosomes sourced from mesenchymal stem cells (MSC-EXOs) have become a promising therapeutic tool for sepsis-induced myocardial dysfunction (SMD). Our previous study demonstrated that Apelin pretreatment enhanced the therapeutic benefit of MSCs in myocardial infarction by improving their paracrine effects. This study aimed to determine whether EXOs sourced from Apelin-pretreated MSCs (Apelin-MSC-EXOs) would have potent cardioprotective effects against SMD and elucidate the underlying mechanisms.

Titin truncating variants (TTNtv) are the main genetic cause of dilated cardiomyopathies (DCMs). The phenotype and prognosis of probands have been evaluated in several large cohorts. However, few data are available on intrafamilial expressivity.
