The aortic valve is a semilunar valve with three leaflets, which lies at the junction of left ventricle and aorta. It allows unidirectional blood flow from the left ventricle to the aorta and the rest of the body. Because of the highly complex and sophisticated cellular and molecular functions, the thin valve leaflet can withstand extreme mechanical and hemodynamic forces with every cardiac cycle. Various factors including age and congenital defects can compromise the normal valvular function...

With the widespread use of low-dose computed tomography for lung cancer screening, the detection rate of pulmonary lesions manifesting as ground-glass opacities (GGOs) has been increasing dramatically. The vol...

Acellular scaffold is mainly composed of collagen, which is sensitive to temperature. The denaturation of collagen, whether immediately or lately after implantation will lead to profound influence on the micro-structure, biological activities of acellular scaffold, and tissue repairing process. However, the in situ thermal stability of acellular scaffold had rarely been investigated previously. In this study, the thermal stability of two acellular scaffolds, acellular bovine pericardium (S1) and...

Massive hemoptysis may be related to a wide spectrum of diseases whose differential diagnosis can be challenging, also due to the medical emergency condition.

The development of systemic chemotherapy including immune checkpoint inhibitors (ICIs) has provided patients with unresectable advanced non-small cell lung cancer (NSCLC) an opportunity to undergo surgical int...

Salmonella spp. cause infectious aortitis through the hematogenous spread of an intestinal Salmonella infection. Salmonella aortitis can result in extensive tissue damage in the aorta leading to complications inc...

CONCLUSIONS: As shown in the mid- and long-term follow-up studies, BalMonocTM svBPP has good performance in RVOT reconstruction. It can effectively eliminate or reduce pulmonary valve regurgitation and protect right heart function. Both réparation à l'Etage ventriculaire (REV) and the modified Barbero-Marcial procedure can bring growth potential and reduce reoperation rate.

Symptomatic aortic valve stenosis (AS) and abdominal aortic aneurysm (AAA) are critical clinical conditions, increasingly more prevalent with aging of the population. Calcific aortic stenosis is the most commo...
