Sutureless versus transcatheter aortic valves in elderly patients with aortic stenosis at intermediate risk: A multi-institutional study.

Objective: This multi-institutional study compares the long-term outcome of elderly patients with severe aortic stenosis and an intermediate risk profile undergoing sutureless versus transcatheter aortic valve implantation.

Methods: From 2008 to 2015, 967 elderly patients (>75 years) with intermediate risk (Society of Thoracic Surgeons score 4%-8%) and isolated aortic stenosis were included in the study (sutureless valve = 481; transcatheter aortic valve implantation = 486). After propensity score matching, 2 matched groups of 291 patients were obtained.

Primary Cutaneous Follicle Center Lymphoma Clear Cell Variant: Expanding the Spectrum of Cutaneous Clear Cell Neoplasms.

Primary cutaneous follicle center lymphoma is the most frequent cutaneous B-cell lymphoma despite the fact that is an uncommon disease. Mild biological behavior and good prognosis characterized this neoplasm with a low aggressiveness compared with classic nodal follicular lymphoma (FL). Rare histological variants have been described.
