SmokyWaters Forum Elite Topics: 6 Posts: 432	Dec 25, 2007 - 10:08 PM       #5 its STENOSIS the earliest complication is paravalvular leak that occurs due to infection in first yeear... second in row is embolization and dehisence/ structural failure in first two years stenosis after 10 years in bioprosthesis is more common

The leaflets may calcify, resulting in stenosis or they may perforate or tear, leading to insuficiency. Thrombosis with embolization is lessened by anticoagulant therapy. Paravalvular leaks are rare complications.

arlete Forum Junior Topics: 60 Posts: 4208	Jan 02, 2008 - 7:20 AM       #10 For an acute onset, yes, a leak problem could happen for both types of prothesis, mainly due to defective surgical technique. After 10 years, the tissues around the valve are already chronically altered in a very firm cicatricial formation, there's no reason to leak. On a chronic case like this, problems related with coagulation (or lack of proper coagulation) are way more common, so embolization, stroke, GI bleeding would be your best bets.
