Event Description
|
Medtronic received information via literature regarding long-term outcomes of mitral valvuloplasty performed by a single surgeon over a four-decade period.All data were retrospectively collected from a single center between february 1972 and april 2008.The study population included 1503 patients (predominantly male, mean age 60.3 years), 178 of whom were implanted with medtronic duran ancore annuloplasty rings and 9 were implanted with medtronic cg future annuloplasty rings (no serial numbers provided).Among all patients, overall 30-day mortality was 1.3% with operative mortality by decade at 0% in the 1970's, 1.8% in the 1980's, 1.4% in the 1990's and 1.1% in the 2000's.No further information was provided.Based on the available information medtronic product was not directly associated with the deaths.Among all patients, adverse events included: acute dissection of the ascending aorta, moderate-severe mitral regurgitation and moderate-severe mitral stenosis requiring surgical correction, severe systolic anterior leaflet motion after repair requiring surgical correction.Based on the available information medtronic product may have been associated with the adverse events.No additional adverse patient effects or product performance issues were reported.
