“…No tricuspid regurgitation or reinfection at 6-month follow-up was reported. 10 Other case studies also found favorable short-term outcomes in tricuspid and mitral valve repairs with CorMatrix, reporting successful repairs, excellent valve function, and good hemodynamic results at 3-month followup. 11,12 Luk and associates, however, reported more long-term results with 10 and 12-month follow-up outcomes and found delayed post-operative infection and perforation of the MV leaflet after histological examination of explanted CorMatrix in 2 adults.…”

Background: Aortic cusp extension is a technique for aortic valve (AV) repairs in pediatric patients. The choice of the material used in this procedure may influence the time before reoperation is required. We aimed to assess post-operative and long-term outcomes of patients receiving either pericardial or synthetic repairs. Methods: We conducted a single center, retrospective study of pediatric patients undergoing aortic cusp extension valvuloplasty (N=38) with either autologous pericardium (n=30) or CorMatrix (n=8) between April 2009 and July 2016. Short and long-term postoperative outcomes were compared between the two groups. Freedom from reoperation was compared using Kaplan Meier analysis. Degree of aortic stenosis (AS) and aortic regurgitation (AR) were recorded at baseline, post-operatively, and at outpatient follow-up. Results: At five years after repair, freedom from reoperation was significantly lower in the CorMatrix group (12.5%) compared to the pericardium group (62.5%) (P = 0.01). For the entire cohort, there was a statistically significant decrease in the peak trans-valvar gradient between pre- and post-operative assessments with no significant change at outpatient follow-up. In the pericardium group, 28 (93%) had moderate to severe AR at baseline which improved to 11 (37%) post-operatively and increased to 21 (70%) at time of follow-up. In the biomaterial group, 8 (100%) had moderate to severe AR which improved to 3 (38%) post-operatively and increased to 7 (88%) at time of follow-up. Conclusion: In terms of durability, the traditional autologous pericardium may outperform the new CorMatrix for AV repairs using the cusp extension method.

Introduction Infective endocarditis (IE) on the tricuspid valve usually requires the complete resection of the infected tissue and implantation of a valve prosthesis. Aim We assumed that total elimination of artificial material and implantation of the entirely patient-derived biological material would reduce the recurrence of IE. Material and methods The group consisted of 7 consecutive patients who underwent implantation of a cylindrical valve created from the patient’s own pericardium in the tricuspid orifice. There were only men aged 43 to 73 years. Isolated tricuspid valve reimplantation with a pericardial cylinder was performed in 2 patients. Five (71%) patients needed additional procedures. The postoperative follow-up ranged from 2 to 32 months (median: 17 months). Results In patients who underwent isolated tissue cylinder implantation, the average extracorporeal circulation (ECC) time was 77.5 minutes and aortic cross-clamp time was 58 minutes. In cases where additional procedures were performed the ECC and X-clamp times were 197.4 and 156.2 minutes, respectively. The function of the implanted valve was examined after weaning from the ECC by transesophageal echocardiogram, followed by transthoracic echocardiogram on day 5–7 after surgery revealed normal function of the prosthesis in all patients. There was no operative mortality. Two late deaths were observed. Conclusions In the follow-up period none of the patients had a recurrence of IE within the pericardial cylinder. Degeneration with subsequent stenosis of the pericardial cylinder occurred in 3 patients. One patient was reoperated on; one had a transcatheter valve-in-valve cylinder implantation.
