BACKGROUND: Percutaneous pulmonary valve replacement (PPVR) has achieved standard of care for the management of dysfunctional right ventricular outflow tract.
AIM: Because of increasing reports of Melody(®) valve (Medtronic, Inc., Minneapolis, MN, USA) infective endocarditis (IE), we aimed to evaluate its incidence and predictors of occurrence.
METHODS: We collected data on all patients who received a Melody valve in the pulmonary position from 2009 to 2012.
RESULTS: A total of 86 consecutive patients underwent PPVR from 2009 to 2012; of these, five developed IE (5.8%). Freedom from IE was 91% at 50 months. Baseline demographics, type of conduit, PPVR procedural success, residual gradients and in situ duration of Melody valve were similar in IE and non-IE patients. A significant number of IE patients had additional unprotected invasive procedures during follow-up and abruptly discontinued antiplatelet therapy (P=0.0139 and P=0.002, respectively). The cumulative probability of survival without cardiovascular events for IE patients was 20% at 20 months, compared with 98.1% for non-IE patients (P<0.0001). Death was statistically associated with IE.
CONCLUSION: Early- and late-onset IE of the Melody valve is emerging as a catastrophic complication of PPVR. Abrupt aspirin discontinuation and additional unprotected invasive procedures during follow-up are significant predictors of Melody valve IE. Owing to its rapidly progressive nature, aggressive invasive management should not be delayed.
