Lawley et al., in a meta-analysis of 11 studies capturing 499 pregnancies among women with heart valve prosthesis
, pooled estimate of maternal mortality was 1.2/100 pregnancies, for mechanical valves subgroup 1.8/100 and bioprosthetic subgroup 0.7/100, overall pregnancy loss 20.8/100 pregnancies, perinatal mortality 5.0/100 births, and thromboembolism 9.3/100 pregnancies .
Transcatheter Technologies GmbH is a start-up medical device company that's developing a next-generation transcatheter aortic heart valve prosthesis
. The company is taking on the big boys in what's becoming an increasingly competitive transcatheter aortic valve implantation (TAVI) sector.
The transapical TAVI system consists of both the Cathlete delivery system and the JenaValve heart valve prosthesis
. The system can be used to treat patients who cannot have conventional open-heart surgery.
