A pulmonary artery aneurysm is a rare, heterogeneous disease for which there are currently no surgical guidelines. We present the case of a symptomatic patient presenting with a large aneurysm of the distal pulmonary trunk and left pulmonary artery. The aneurysm was resected through a full median sternotomy under cardiopulmonary bypass and aortic cross-clamping. The reconstruction was performed using a straight vascular prosthesis to connect the proximal pulmonary trunk to the left pulmonary artery with the lateral reimplantation of the right pulmonary artery. We find this surgical technique to be simple, effective, and reproducible by colleagues encountering similar cases.

Background: To evaluate the clinical diagnostic value of third-generation dual-source CT for pulmonary embolism, focusing on the optimization of dual-source CT scanning with dynamic reconstruction in acute pulmonary embolism (PE) and various imaging manifestations.
Methods: Eighty-two patients with pulmonary embolism were enrolled and randomly divided into standard CT angiography (SCTA) and dynamic CT angiography (DCTA). DCTA patients were divided into dynamic CT angiography arterial phase (DCTAa), time phase Angiography reconstruction (TMIP-CTA), and 4D noise reduction TMIP-CTA according to the image reconstruction.

Long non-coding RNA (lncRNA) may be involved in dysfunction of pulmonary artery endothelial cells (PAEC) and, thus, in pulmonary arterial hypertension (PAH) pathobiology. We screened the RNA expression profile of commercial human PAEC (hPAEC) exposed to increased hydrostatic pressure, and found that the lncRNA Down syndrome critical region 9 (DSCR9) was the most regulated transcript (log2FC 1.89 vs control).

Background: Patients with severe tricuspid regurgitation (TR) typically present with heterogeneity in the extent of cardiac dysfunction and extra-cardiac comorbidities, which play a decisive role for survival after transcatheter tricuspid valve intervention (TTVI).
Objectives: This aim of this study was to create a survival tree-based model to determine the cardiac and extra-cardiac features associated with 2-year survival after TTVI.
Methods: The study included 918 patients (derivation set, n = 631; validation set, n = 287) undergoing TTVI for severe TR.
