BACKGROUND: The Melody transcatheter pulmonary valve has been implanted successfully worldwide since its first implant in 2000. The vast majority of these valves have been implanted in pulmonary homografts. In our institution, the most common valve used for pulmonary valve replacement is the Medtronic Freestyle stentless porcine aortic heterograft. OBJECTIVE: We describe our experience implanting the Melody valve within the Freestyle heterograft. METHODS: Retrospective chart review was performed...

Percutaneous pulmonary valve implantation is now an acceptable treatment option. The Edwards SAPIEN valve, intended for transcatheter aortic valve implantation, has been used in patients whose landing zone diameter is >22 to 24 mm which is not suitable for Melody valve. We report a patient in whom we successfully placed the latest generation, Edwards SAPIEN 3 (ES3) in the pulmonary position. However, because of the short covered portion of this valve, there was a significant paravalvular leak through the stent struts requiring implantation of a second ES3 valve...

OBJECTIVE: The aim of this study was to describe previously unrecognised or under-recognised adverse events associated with Melody® valve implantation. BACKGROUND: In rare diseases and conditions, it is typically not feasible to conduct large-scale safety trials before drug or device approval. Therefore, post-market surveillance mechanisms are necessary to detect rare but potentially serious adverse events. METHODS: We reviewed the United States Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database and conducted a structured literature review to evaluate adverse events associated with on- and off-label Melody® valve implantation...

AIMS: We reviewed our center experience in the field of transcatheter pulmonary valve-in-valve implantation (TPViV), that is emerging as a treatment option for patients with pulmonary bioprosthetic valve (BPV) dysfunction. METHODS: Between April 2008 and September 2015, a total of six patients with congenital heart disease (four men) underwent TPViV due to stenosis of preexisting BPV. Four patients received a Melody Medtronic Transcatheter Pulmonary Valve and two an Edward Sapien Valve...

The Melody® transcatheter pulmonary valve system was developed for placement within right ventricle-to-pulmonary artery conduits in patients with CHD for treatment of stenosis or regurgitation, providing an alternative to open-heart surgery. Abnormal systemic venous connections altering the catheter course to the right ventricle-to-pulmonary artery conduit may present a challenge to Melody® valve implantation. We present two such cases, in which the Melody® valve was successfully implanted in teenage patients with congenitally corrected transposition of the great arteries after Senning atrial switch operation...

A 30-year-old female with tricuspid valve atresia, ventricular septal defect, and atrial septal defect had a neonatal modified Blalock Taussig shunt and a Fontan-Björk operation performed at five years of age. She did well initially but progressively developed signs of systemic congestion due to severe homograft stenosis and underwent successful percutaneous implantation of a Melody(®) pulmonary valve (Medtronic, Minneapolis, MN, USA) in the "tricuspid" position.

Group B streptococcus (GBS) is recognised as one of the leading organisms in early-onset neonatal sepsis but is also a cause of late-onset GBS septicaemia, meningitis and rarely, infective endocarditis (IE). We report a case of a healthy term neonate who developed GBS septicaemia and meningitis having presented with parental concern and poor feeding. Subsequent identification and treatment of GBS resulted in the requirement for long-line intravascular access in order to administer antibiotic therapy. One week later, after repeated parental concern and symptoms of shortness of breath, the neonate presented to Accident and Emergency and subsequently a Paediatric Cardiorespiratory Intensive Care Unit where emergency resuscitation procedures were required and diagnosis of severe IE affecting the mitral valve was made...

Pseudoaneurysm formation is a rare but potentially life-threatening complication after surgical repair of congenital heart disease. We present a boy with truncus arteriosus communis 14 years after homograft placement in pulmonary position. On follow-up, he presented progressive chronic homograft degeneration. Moreover, a large pseudoaneurysm in the right ventricular outflow tract was surprisingly depicted. We opted for a two-stage interventional approach.

Current delivery systems for the Sapien XT valve for the native pulmonary valve are unacceptable stiff and poorly design for implantation in the pulmonary outflow tract. This report details improvisation of the Melody Ensemble for easier pulmonary outflow tract delivery of the Sapien XT valve. The unacceptable cost of the utilization of two delivery systems for valve implantation, requires industry development of an safe, effective delivery system appropriate for the pulmonary outflow tract.

Percutaneous valved stent implantation is precluded in small infants because large delivery sheaths and large devices. We describe a procedure in a 1-year-old boy in whom a 19 mm Epic™ valve in tricuspid position had become dysfunctional. As the internal diameter of the prosthetic valve was about 16 mm, the only available valve was the Melody™ valved stent. Technical modifications were required to address issues like venous access, the bulky delivery system, and the length of the valved stent. The Melody™ valved stent was surgically trimmed and mounted on a 16 mm Tyshak balloon, access was provided transhepatically through a short 18 Fr sheath...

OBJECTIVES: Mitral valve replacement (MVR) in young children is limited by the lack of small prostheses. Our institution began performing MVR with modified, surgically placed, stented jugular vein grafts (Melody valve) in 2010. We sought to describe key echocardiographic features for pre- and postoperative assessment of this novel form of MVR. METHODS: The pre- and postoperative echocardiograms of 24 patients who underwent Melody MVR were reviewed. In addition to standard measurements, preoperative potential measurements of the mitral annulus were performed whereby dimensions were estimated for Melody sizing...

BACKGROUND: The most common reason for reintervention after a Björk modification of the Fontan procedure, in which the right ventricle (RV) is incorporated into the pulmonary circulation by connecting the right atrial (RA) appendage to the RV directly or with an extra-anatomic graft, is obstruction or regurgitation of the RA-RV connection. Transcatheter implantation of a valved stent is an appealing option for the treatment of RA-RV conduit dysfunction in these patients. In the present study, we assessed early and intermediate results after transcatheter valve implantation within an obstructed or regurgitant RA-RV modified Fontan pathway...

BACKGROUND: Although percutaneous Melody valve implant has become an accepted alternative to surgical pulmonary valve replacement in patients with congenital heart disease (CHD), the benefit regarding frequency and severity of arrhythmias remains undefined. OBJECTIVE: This study evaluated the impact of Melody valve implant on the type and frequency of arrhythmias during cardiopulmonary exercise testing (CPET) and subsequent clinical outcome. METHODS: As part of the phase I Melody valve clinical trial, 136 patients with CHD underwent prospective serial evaluation including CPET prior to, 6 months after, and annually for 5 years...

This retrospective study aims to evaluate radiation exposure by three-dimensional rotational angiography (3DRA) during trans-catheter Melody pulmonary valve (TMPV) procedures. 3DRA has been reported to have added value in the management of complex congenital heart disease aiding in the performance of interventional procedures albeit with concerns of higher radiation exposure. We test the hypothesis that 3DRA does not cause additional radiation exposure during TMPV procedures. We analyzed all 81 TMPV procedures performed at St...

Bioprosthetic valve thrombosis is an uncommon complication. We report two young women with prior uncomplicated percutaneous pulmonary valve replacement (Melody(®) , Medtronic, Inc. Minneapolis, MN) who later developed symptomatic pulmonary emboli and pulmonary valve dysfunction without evidence of infection. Thrombophilia risk factors included oral contraceptive use and mild thrombophilia. Both experienced recovery of valve function following anticoagulation. Acute changes in Melody(®) valve function should prompt a thorough investigation for and treatment of potential thrombotic causes...

BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) using the bovine jugular vein Melody(®) valve (Medtronic Inc., Minneapolis, MN, USA) is safe and effective. However, post-procedural complications have been reported, the reasons for which are unclear. OBJECTIVE: To assess the impact of PPVI procedural steps on valvular histology and leaflet mechanical behaviour. METHODS: Three different valved stents (the Melody(®) valve and two homemade stents with bovine and porcine pericardium) were tested in vitro under four conditions: (1) control group; (2) crimping; (3) crimping plus inflation of low-pressure balloon; (4) condition III plus post-dilatation (high-pressure balloon)...

Reconstructing the right ventricular outflow tract and pulmonary valve via a bovine-derived valve conduit such as Matrix-P-Xenograft is a common surgical repair technique for pulmonary atresia and ventricular septal defect. After conduit degeneration due to calcification or aneurysmal dilatation, percutaneous transvenous stenting of the right ventricular outflow tract followed by pulmonary valve implantation has become the standard interventional treatment. Applied to stenotic conduits, the method is considered safe and effective...
