Hello Ralph... Great to hear that all went well with your 2nd surgery. I'am haviing my cow valve replaced with a mechanical valve after only three years at the CC Dec 12. My Doc notice the leak coming from the inside of the tip of one of the leaflets after the 2nd year. The difference this time around im handling it much better, Im a veteran at this. All the best in your recovery.
