On (b)(6) 2013, an aortic valve replacement (avr) was performed and this 21 mm trifecta valve was implanted.On (b)(6) 2017, re-do avr was performed and this valve was explanted.Ex vivo, one leaflet appeared to be torn at the commissure along the stent post between the non-coronary cusp (ncc) and right coronary cusp, which extended from the top of the stent post toward the base of cusp on both sides.The torn leaflets became prolapsed from the stent post and a relatively large perforation was observed at the nadir close to the torn/prolapsed site of ncc and circumferential pannus was observed on the inflow side of this valve.A 19 mm sorin bicarbon mechanical valve was implanted.The patient was reported to be in stable condition postoperatively.
