Right ventricular heart failure (RV HF) is the leading cause of death in pulmonary arterial hypertension (PAH). Relevance of the low-risk status assessment using available diagnostic tools requires a reliable confirmation. The study aimed to evaluate right ventricular perfusion and glucose metabolism using positron emission tomography (PET)/computed tomography (CT) with [13N]-ammonia and [18F]-fluorodeoxyglucose ([18F]-FDG) in 30 IPAH patients (33.

Objectives: To investigate glymphatic function in idiopathic normal pressure hydrocephalus (iNPH) using the diffusion tensor image analysis along the perivascular space (DTI-ALPS) method and to explore the associations of ALPS index with ventriculomegaly and white matter hyperintensities (WMH).
Materials And Methods: This study included 41 patients with iNPH and 40 age- and sex-matched normal controls (NCs). All participants underwent brain MRI.

Idiopathic pulmonary arterial hypertension (iPAH) is a rare, rapidly progressive disease associated with high morbidity and mortality. It is characterized by endothelial dysfunction within the pulmonary vascular bed and gradually leads to an increase in the pulmonary vascular resistances. Its non-specific symptomatology delays the diagnosis and brings the most severe forms to right ventricular failure.

Background: The relationship between premature ventricular contractions (PVC) and right ventricular (RV) function is not widely known. Left ventricular (LV) dysfunction due to PVC is known as PVC-induced cardiomyopathy (PIC) and suppressing the PVC substrate would improve LV function. The effect of PVC ablation on changes in RV function in patients with subtle RV subclinical dysfunction remains unknown.

Hypereosinophilic syndrome (HES) is traditionally described as chronic peripheral eosinophilia with involvement of various organs and systems, including the heart and nervous system. In this report, we describe cardiac involvement and border zone stroke in a patient with idiopathic HES. A 37-year-old woman presented with sudden right-sided weakness and slurred speech, which began four days before admission, accompanied by palpitations, retrosternal exertional chest discomfort, dry cough, and progressive shortness of breath over approximately two months.
