“…A selective propensity of bovine jugular tissue (the precursor of the Melody valve leaflets) to histological lesions during procedural steps45 and to bacterial adherence46 was shown in in‐vitro studies, especially after procedural manipulation‐induced leaflet damage 46. These findings are in line with the observed higher propensity of valves with bovine jugular vein leaflets (Melody valve and Contegra graft) to IE than pulmonary homografts 18, 19, 47.…”

BackgroundInfective endocarditis (IE) after transcatheter pulmonary valve implantation (TPVI) in dysfunctioning right ventricular outflow tract conduits has evoked growing concerns. We aimed to investigate the incidence and the natural history of IE after TPVI with the Melody valve through a systematic review of published data.Methods and ResultsPubMed, EMBASE, and Web of Science databases were systematically searched for articles published until March 2017, reporting on IE after TPVI with the Melody valve. Nine studies (including 851 patients and 2060 patient‐years of follow‐up) were included in the analysis of the incidence of IE. The cumulative incidence of IE ranged from 3.2% to 25.0%, whereas the annualized incidence rate ranged from 1.3% to 9.1% per patient‐year. The median (interquartile range) time from TPVI to the onset of IE was 18.0 (9.0–30.4) months (range, 1.0–72.0 months). The most common findings were positive blood culture (93%), fever (89%), and new, significant, and/or progressive right ventricular outflow tract obstruction (79%); vegetations were detectable on echocardiography in only 34% of cases. Of 69 patients with IE after TPVI, 6 (8.7%) died and 35 (52%) underwent surgical and/or transcatheter reintervention. Death or reintervention was more common in patients with new/significant right ventricular outflow tract obstruction (69% versus 33%; P=0.042) and in patients with non‐streptococcal IE (73% versus 30%; P=0.001).ConclusionsThe incidence of IE after implantation of a Melody valve is significant, at least over the first 3 years after TPVI, and varies considerably between the studies. Although surgical/percutaneous reintervention is a common consequence, some patients can be managed medically, especially those with streptococcal infection and no right ventricular outflow tract obstruction.

“…These results suggested a cumulative effect of both crimping and balloon-expansion stages on the architecture of valvular leaflets. Other authors observed similar lesions with the bovine pericardial valved stent, using various assessment techniques [15,[17][18][19][20]. Unlike Amahzoune et al, we did not find that bovine pericardial leaflets were significantly injured during in vitro manipulations [16].…”

“…Traumatic injury to biological valve leaflets has been reported during valved stent preparation [15,16]. In a recent work, we demonstrated that there was selective adhesion of Staphylococcus aureus and S. sanguinis pathogenic strains on healthy Melody ® valve tissue, which increased after implantation procedural steps [17]. In this in vitro study, we aimed to assess the effects of PPVI procedural steps on the histological and mechanical properties of Melody ® valve leaflets, and to compare these results with other tissues used for valved stent fabrication (i.e.…”

“…We clearly demonstrated for the first time that BJV leaflets were the most histologically altered by in vitro manipulations. In a recent work, we hypothesized that the transverse fractures observed on traumatized leaflets might constitute a possible target for bacterial germs to adhere to, and could possibly explain the high incidence of IE involving Melody ® valves [17,[26][27][28]. However, scanning electron microscopy revealed that bacteria adhered over the entire sample surface in a heterogeneous way.…”

“…The risk of endocarditis on implanted Melody was reported and analyzed over prostheses implanted in RVOT, and several in-vitro studies [8,9]. The risk of infection and damage of the Melody valve exposed for bacterial infection is similar to other biological valves, and implanted homografts [10].…”

We present a case of emergency mitral valve replacement with the first -to the best of our knowledge -use of Melody balloon expandable stented bioprosthesis in a 2-years-old patient with acute endocarditis, subsequent mitral (bicuspid) valve incompetence after aggressive infective destruction, with the symptoms of critical multiorgan failure.The patient with a history of rapid deterioration after 2-weeks-long septicemia in the course of acute endocarditis was operated for life-saving indications. Melody valve was expanded over 16 mm TyShak balloon and implanted into a mitral position (Melody-MVR) with good result.Based on actual knowledge concerning heart valves reconstructions and institutional experience we conclude that infected mitral valve in children should be primary repaired, nevertheless Melody valve could be reasonable considered as a mitral prosthesis in patients with non-reparable conditions.
