ABSTRACT
Background:
Infective endocarditis (IE) is one of the major complications following pulmonary valve replacement (PVR). This analysis hopes to evaluate the incidence, outcomes and possible risk factors of IE associated with trans-catheter and surgical placement of a bovine jugular vein (BJV) graft in the pulmonary position.Methods:
In this single-center retrospective study, all records of trans-catheter and surgical PVR from 3/2010 to 12/2019 were reviewed. IE was defined as positive blood cultures, with vegetations seen on echocardiography or sudden increase in peak gradient across the valve or vegetations confirmed at time of valve replacement. Poor dental hygiene1.dental procedures without S.B.E prophylaxis AND/OR 2.one or more dental cavities, caries, dental abscess.Results:
165 patients had PVR with BJV107 trans-catheter and 63 surgical. 7%(12/170) of PVRs developed IE(cathetern = 10, surgeryn = 2) at a median time from valve placement of 38 months. The incidence of IE in the catheter group3-per-100patient-years and in surgical group1-per-100patient-years. Multivariate cox regression showed that poor dental hygiene was significantly associated with IE [HR(95% CI)16.9(4.35-66.2)](p value <.001). Kaplan-Meier curves showed a significant difference in freedom from IE between patients with poor and appropriate dental hygiene (p value<.001).Conclusions:
There is a 7% incidence of IE with the use of BJV grafts in the pulmonary position at mid-term follow-up. Though the rate in catheter placed BJV seems 3x higher than surgically placed ones, their cohorts are quite different making this comparison flawed. Poor dental hygiene is a strong predictor for post-operative IE and offers a significant opportunity for lowering the rate of infective endocarditis.Palavras-chave
