Introduction Acquired pulmonary artery stenosis is a rare entity that has scarcely been described in the literature, and it is mainly associated with compression of the pulmonary artery trunk and its branches by mediastinal tumors (teratomas and lymphomas). We report the case of a young patient with non-Hodgkin lymphoma in the anterior mediastinum that led to extrinsic compression and local luminal invasion of the pulmonary artery trunk, causing significant impact on the right heart chambers, with subsequent improvement after chemotherapy.

Abstract An 82-year-old patient with severe aortic valve stenosis and high risk for conventional surgery due to chronic renal dysfunction and restrictive lung disease underwent transfemoral transcatheter aortic valve implantation (TAVI) using a self-expanding Navitor® prosthesis (Abbott). Immediately after implantation, valve dysfunction was observed, characterized by inversion of the right coronary leaflet, resulting in severe acute prosthetic regurgitation and hemodynamic instability. Therefore, a 21.5 mm balloon-expandable Myval® prosthesis was also implanted (TAV-in-TAV). The critical condition was resolved with immediate hemodynamic […]

Abstract Echocardiographic assessment of mitral regurgitation (MR) is multiparametric and often challenging. The artifact known as splay has been described as an additional tool for estimating the severity of regurgitation. The term refers to a side-lobe artifact that forms a horizontal arc on color Doppler imaging. This same phenomenon can also be observed in other valvular heart diseases, such as aortic regurgitation. In 2020, Wiener et al. reported that splay was present in 81% of cases of significant MR, reaching […]
