Incidence and predictors of Melody® valve endocarditis: a prospective study.

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.

Impact of right ventricular outflow tract size and substrate on outcomes of percutaneous pulmonary valve implantation.

Background: Owing to the wide variety of surgical substrates used for right ventricular outflow tract (RVOT) reconstruction, the predictors of successful outcomes in such patients are unclear.

Aims: To compare haemodynamic outcomes of percutaneous pulmonary valve implantation (PPVI) in patients with dysfunctional RVOT.

Methods: This was a multicentre prospective study on all consecutive patients who underwent PPVI from May 2008 to December 2009.
