Outcomes of Treatment for Infective Endocarditis Following Transcatheter Pulmonary Valve Replacement

Transcatheter pulmonary valve replacement (tPVR) is a key therapy in RVOT pathologies but is associated with long term risks such as infective endocarditis (IE). In fact, some reports claim a higher IE risk compared to surgical pulmonary valve replacement. This paper investigates outcomes to different management strategies used to treat IE in patients who underwent tPVR. A total of 69 cases were identified with 98 admissions due to a readmission rate of 29 percent. During the initial admission, surgical rates were 22 percent. Surgical rates were 36 percent overall, as the likelihood of surgical intervention increased with each subsequent admission. Mortality rate in the overall and surgical cohort was 4.3 percent and 8 percent respectively.
