Echo and doppler controlled behavior of aortic ATS valve comparison with the aortic SJM
Prosthetic mechanical valves differ from one another in regard to several characteristics including mainly thrombogenicity and hemodynamic profile. The ATS heart valve prosthesis is a bileaflet Pyrolite carbon heart valve that is nearly identical to the St. Jude prosthesis (SJM). ATS is different from the SJM prosthesis in some ways including valve pivot design and absence of pivot guards. It is, thus, a second generation bileaflet prosthesis and as such merits it to be compared with the SJM in terms of hemodynamic performance. The aim of the study was to compare at the 10th post operative day and 180th post operative day the echocardiographic assessment of implanted aortic valve prosthesis (ATS versus SJM).
