As reported by our (b)(4) affiliate, after post-dilation with additional volume the 23mm sapien 3 valve had moderate central leak and a valve-in-valve procedure was performed.At the beginning of the procedure, the right coronary artery was protected due to low height of 7.9mm.A 23mm sapien 3 valve was deployed without problem in a 70:30 aortic/ventricular position.Post-deployment, echo showed mild paravalvular leak (pvl) and post-dilation was performed with an additional 1ml contrast solution added to the nominal volume.After post-dilation, moderate central leak was observed from the right coronary cusp ¿ left coronary cusp.The echo showed a motion abnormality in the leaflets.A new 23mm s3 valve was implanted in the first valve.The procedure was completed after confirming the final pvl was trivial.A guiding catheter had been inserted through the s3 valve's stent for coronary angiography post valve deployment.At that time, the physician felt some resistance.At the end of the procedure, the physician speculated that the valve leaflet might have been damaged while manipulating the guiding catheter post deployment of the first valve.However, it was unclear whether the resistance was a cause of the event.
