TRANSCATHETER VERSUS SURGICAL AORTIC VALVE REPLACEMENT: FIRST EXPERIENCE WITH A NEW TAVI SYSTEM.

Objective: The aim: to reveal early results after transapical TAVI with a new self-manufactured XPand system, comparing them with SAVR and common transfemoral TAVI outcomes.

Patients And Methods: Materials and methods: Eighty-four patients (mean age 79,5±10,2 years) with severe aortic stenosis were operated on from January 2016 to February 2019. Nine patients had undergone the TAVI (two with transfemoral access route and seven with transapical, using the XPand system).

OPTIMIZED METHOD OF BOVINE PERICARDIUM DECELLULARIZATION FOR TISSUE ENGINEERING.

Objective: The aim: To investigate the effectiveness of using low concentrations of sodium dodecyl sulfate (SDS) and cross-linking with EDC/NHS in the decellularization process to create a potential bioimplant for cardiac surgery.

Patients And Methods: Materials and methods: Pericardial sacs were derived from 12-18 months bulls. Tissue decellularization was performed by using 0.
