Why the study?
Does a new pyrolytic carbon tilting disc prosthesis improve survival and reduce embolism compared to older prostheses in patients undergoing heart valve replacement?
Does a new pyrolytic carbon tilting disc prosthesis improve survival and reduce embolism compared to older prostheses in patients undergoing heart valve replacement?
A new pyrolytic carbon tilting disc prosthesis demonstrated satisfactory mid-term survival and acceptable embolism rates, appearing favorable compared to historical Starr-Edwards and Björk-Shiley prostheses.
No takes yet. Share an insight, caveat, or question.
These mid-term results support further evaluation of the prosthesis; leaves open superiority over historical valves in randomized trials.
Pellegrini et al. (1982) studied this question.
