Replacement of pulmonary artery trunk in sheep using tubular valved heterograft in non-aldehydic preservation.

Introduction: The cardiac bioprostheses are related to thromboembolic events, infectious and degenerative diseases. Wear is mainly attributed to the denaturation of collagen. Glutaraldehyde, the predominant method of preservation of bioprostheses, favors the calcification process and limits their durability.

Syringomas are benign adnexal tumors derived from the intraepidermal portion of eccrine sweat ducts. Clinically, they usually appear as small yellow or skin-colored papules ranging from 1-3 mm in diameter on the lower eyelids. The condition of eruptive syringomas is a clinically distinct, uncommon variant of syringomas.
