This study aims to develop and validate a standardized methodology for creating high-fidelity, custom-made, patient-specific 3D-printed vascular models that serve as tools for preoperative planning and training in the endovascular treatment of peripheral artery disease (PAD). Ten custom-made 3D-printed vascular models were produced using computed tomography angiography (CTA) scans of ten patients diagnosed with PAD. CTA images were analyzed using Syngo.

Background: This study aimed to determine whether artificial intelligence (AI)-based automated assessment of left atrioventricular coupling index (LACI) can provide incremental value above other traditional risk factors for predicting mortality among patients with severe aortic stenosis (AS) undergoing coronary CT angiography (CCTA) before transcatheter aortic valve replacement (TAVR).
Methods: This retrospective study evaluated patients with severe AS who underwent CCTA examination before TAVR between September 2014 and December 2020. An AI-prototype software fully automatically calculated left atrial and left ventricular end-diastolic volumes and LACI was defined by the ratio between them.
A 51-Year-Old Man With Dyspnea and a Pulmonary Nodule.
Chest

State Key Laboratory of Respiratory Health and Multimorbidity, Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences, Peking Union Medical College, Beijing, China.
A 51-year-old man presented with chest tightness, exertional dyspnea, and occasional chest pain for 2 years. The patient visited his local hospital initially, and CT scan revealed a ground glass opacity (GGO) located in the right upper lobe (Fig 1A). He was diagnosed as having pulmonary infection and treated with levofloxacin for 12 days.

Background: Cancer and cancer treatment may accelerate the development of cardiovascular disease. With the improved prognosis of cancer survivors, cardiovascular events are increasing in this patient group. However, it is unknown whether the prevalence of coronary atherosclerosis is increased in patients with a history of cancer.

Aneurysms of the superior vena cava are rare vascular malformations of systemic veins. This report presents the case of a 27-year-old woman with an incidental finding of mediastinal shadow widening on the chest roentgenogram that was confirmed by computed tomographic angiography to be a superior vena cava saccular aneurysm >4 cm in diameter. Surgical resection was recommended on the basis of aneurysmal size and shape and was performed through median sternotomy by using cardiopulmonary bypass.
