    ABSTRACT: OBJECTIVE. THE AIM OF THIS STUDY WAS TO DETERMINE EARLY AND LONG-TERM RESULTS AFTER TRANSCATHETER PULMONARY VALVE IMPLANTATION (TPVI) PERFORMED WITH THE USE OF MEDTRONIC MELODY AND EDWARDS SAPIEN VALVES IN PATIENTS WITH FULL CONDUIT OR PATCHED RIGHT VENTRICULAR OUTFLOW TRACT (RVOT) DYSFUNCTION. METHODS AND RESULTS. THE STUDY COMPRISED 40 CONSECUTIVE PATIENTS (FULL CONDUIT, N = 25; RVOT PATCH, N = 15) WHO UNDERWENT TPVI BETWEEN DECEMBER 2008 AND APRIL 2012. TPVI WAS SUCCESSFULLY PERFORMED IN 37 PATIENTS (92.5%). THE GRADIENT ACROSS RVOT DECREASED FROM 82.96 ± 37.90 MM HG TO 34.33 ± 22.2 MM HG ON THE DAY FOLLOWING TPVI (P<(><<)>.001) AND REMAINED LOW AT FOLLOW-UP OF 20.4 ± 11.4 MONTHS. THE COMPETENCY OF THE PULMONARY VALVE WAS RESTORED AND MAINTAINED DURING THE FOLLOW-UP. (B)(4) CLASS, RIGHT VENTRICLE END-DIASTOLIC VOLUME, AND RIGHT VENTRICULAR EJECTION FRACTION ALL IMPROVED AS SOON AS 1 MONTH AFTER THE PROCEDURE. INFECTIVE ENDOCARDITIS WAS OBSERVED IN 4 PATIENTS (1 DIED). FOUR PATIENTS UNDERWENT SURGERIES DUE TO ENDOCARDITIS, HOMOGRAFT RUPTURE, STENT MIGRATION, AND EARLY VALVE COMPRESSION. CONCLUSION. TPVI MAY BE PERFORMED SAFELY AND EFFECTIVELY IN PATIENTS WITH RIGHT VENTRICLE-PULMONARY ARTERY CONDUIT AND IN SELECTED PATIENTS WITH PATCHED RVOT. THE STUDY POPULATION CONSISTED OF 40 CONSECUTIVE PATIENTS (AGE RANGE, 13 TO 58 YEARS; MEAN AGE, 25.4 ± 8.7 YEARS; 22 MALES) WHO UNDERWENT TPVI AT ONE CENTER BETWEEN DECEMBER 2008 AND APRIL 2012. THE FULL RIGHT VENTRICLE (RV) TO PULMONARY ARTERY (PA) CONDUIT WAS IMPLANTED IN 25 PATIENTS (62.5%); 15 PATIENTS (37.5%) HAD THE RVOT EXTENDED WITH THE PATCH. ALL PROCEDURES WERE PERFORMED UNDER GENERAL ANESTHESIA WITH ENDOTRACHEAL INTUBATION. THE FEMORAL OR JUGULAR VEIN (3 CASES) WAS USED FOR ACCESS. BEFORE VALVE IMPLANTATION, ALL PATIENTS UNDERWENT ROUTINE PRESTENTING OF THE TARGET SITE WITH THE INTRASTENT MAX LD BARE-METAL STENT (EV3 ENDOVASCULAR). IN 5 CASES, PRESTENTING AND VALVE IMPLANTATION WERE CARRIED OUT SEPARATELY. IN THESE PATIENTS, THERE WAS NO WAIST AFTER PRESTENTING THE BORDERLINE-SIZE OUTFLOW TRACT, AND THEREFORE IT WAS DECIDED TO DELAY THE VALVE IMPLANTATION FOR 2 MONTHS IN ORDER TO ALLOW PROPER STENT FIXATION AS A RESULT OF TISSUE INGROWTH. THE MELODY VALVE, WHICH WAS MOUNTED ON A 18, 20, OR 22 MM ENSEMBLE DELIVERY SYSTEM (MEDTRONIC, INC), WAS INTRODUCED AND DEPLOYED INTO THE PREIMPLANTED STENT. TWO MAJOR PROCEDURAL COM¬PLICATIONS OCCURRED, BOTH DURING THE PRESTENTING PROCEDURE: RUPTURE OF THE CALCIFIED AORTIC HOMOGRAFT11 AND STENT DISLODG¬MENT. WE ALSO OBSERVED AN EARLY STENT COMPRESSION BY THE CALCIFIED AORTIC MONOCUSP VALVE WITH THE RV-PA GRADIENT. INCREASE FROM 23 MM HG TO 120 MM HG THE DAY AFTER SUC¬CESSFUL MM IMPLANTATION. THE 13 ALL 3 PATIENTS UNDERWENT SURGERY WITHOUT COMPLICATIONS. NONE OF THE SURGICAL REVISIONS LED TO DEATH.
