As reported in a research article, after the valve implantation further surgical intervention was needed in some patients.This was intervention was either implanting an intra-aortic balloon pump, re-exploration for bleeding, pericardial effusion, and paravalular leakage.The results of the investigation are inconclusive since the device was not returned for analysis.Based on the information received, the cause of the reported incident could not be conclusively determined.
