    AS PART OF THE POST MARKET SURVEILLANCE PROCESS, THIS RETROSPECTIVE SINGLE CENTER, SINGLE SURGEON STUDY REPORT PUBLISHED IN PEDIATRIC CARDIOLOGY TITLED "MITRAL VALVE REPLACEMENT IN PEDIATRICS USING AN EXTRACELLULAR MATRIX CYLINDER VALVE: A CASE SERIES" WAS REVIEWED. THIS ARTICLE SUMMARIZES THE RESULTS OF EIGHT (8) CHILDREN UNDER THE AGE OF 2 YEARS WHO UNDERWENT ECM CUSTOM-MADE CYLINDER VALVES FOR MITRAL VALVE REPLACEMENT. THE STUDY STATES THAT THESE PATIENTS WERE TREATED BETWEEN MARCH 2013 AND OCTOBER 2017 USING THE CORMATRIX (NOW AZIYO BIOLOGICS) TYKE 2-PLY EXTRACELLULAR MATRIX MATERIAL (MODEL # / LOT #: UNKNOWN). THIS REPORT IS FOCUSED ON THE PATIENT #3 AS REFERENCED IN TABLE 1: SUMMARY TABLE OF THE EIGHT PATIENTS WHO INITIALLY UNDERWENT MITRAL VALVE REPAIR, HOWEVER UNDER DIRECT INSPECTION, THE SURGEON DETERMINED REPAIR WAS NOT FEASIBLE AND MITRAL VALVE REPLACEMENT WAS PERFORMED DUE TO SEVERE LEFT ATRIOVENTRICULAR VALVE REGURGITATION FROM PRIOR FAILED ATRIOVENTRICULAR SEPTAL DEFECT REPAIR. AT THE AGE OF 5.5 MONTHS, ECM-MV REPLACEMENT WAS PERFORMED AND WITHIN DAYS (0.1 MONTHS POST-OP), THE PATIENT DEVELOPED ACUTE DEHISCENCE OF THE PAPILLARY MUSCLE WITH SEVERE REGURGITATION. PATIENT UNDERWENT SURGICAL PROCEDURE TO REPLACE ECM-MV WITH 16MM MECHANICAL VALVE. ATTEMPTS TO CONTACT THE CORRESPONDING AUTHOR HAVE BEEN SUCCESSFUL AT THIS TIME, HOWEVER, SHOULD ANY ADDITIONAL INFORMATION BE RECEIVED A FOLLOW-UP REPORT WILL BE FILED.
