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.

The pulmonary vasculature plays a pivotal role in the development and progress of chronic lung diseases. Due to limitations of conventional two-dimensional histological methods, the complexity and the detailed anatomy of the lung blood circulation might be overlooked. In this study, we demonstrate the practical use of optical serial block face imaging (SBFI), ex vivo microcomputed tomography (micro-CT), and nondestructive optical tomography for visualization and quantification of the pulmonary circulation's 3D architecture from macro- to micro-structural levels in murine lung samples.

Pulmonary embolism (PE) is a critical condition that arises when clots migrate to the lungs, obstructing pulmonary circulation and posing a significant risk to the patient's health. While the D-dimer test is useful for excluding PE, it is not infallible. This report describes a case where extensive PE was present despite the patient having a normal D-dimer level, emphasizing the importance of a thorough clinical evaluation.

Repair or palliation of pulmonary atresia with intact ventricular septum (PA/IVS) often falls into one of 4 categories: cardiac transplant, 2-ventricular circulation, 1.5 ventricle circulation, or single ventricle circulation. The optimal management strategy has been an area of much debate.
