Transcatheter pulmonary valve placement is emerging as a standard therapy for dysfunctional right ventricular outflow tract conduits. The Melody transcatheter pulmonary valve is indicated for use in the management of pediatric and adult patients with right ventricular outflow tract conduits measuring at least 16 mm in diameter. This is the first reported case of placement in a patient with a left ventricular assist device. We outline the preprocedural evaluation process, the procedural methods, and the outcomes of a successful implantation in a complex patient...

Through a series of complex surgical and interventional procedures including downsizing of an unrestricted atrial septal defect, aortic arch reconstruction, pulmonary artery banding, reversed Potts shunt, and Melody valve in a mitral position, biventricular conversion was successfully achieved in a patient with a distinct borderline left ventricle. By use of these interventional steps, flow-mediated and load-mediated growth of a small left ventricle was observed, highlighting the plasticity of hearts in growing children...

The Potts operation is a surgical option for the treatment of children with suprasystemic pulmonary arterial hypertension (PAH). Its positive hemodynamic effect may be obliterated by pulmonary valvar insufficiency. We describe a case in which the Potts shunt was followed by perventricular Melody valve implantation in the pulmonary position in a 12-kg child with a previously repaired truncus arteriosus communis (TAC) in whom PAH developed. The combined approach using both procedures significantly improved functional capacity and led to spectacular reverse remodeling of the right ventricle seen at 2-year follow-up...

Transcatheter pulmonary valve implantation is established as a valuable option to reconstruct failing right ventricular outflow tract function. Percutaneous tricuspid valve-in-valve or valve-in-ring reconstruction is even applied with increasing acceptance. A 46-year-old woman with a diagnosis of carcinoid-dependent right heart failure underwent surgical bioprosthetic tricuspid and pulmonary valve replacement. Almost 1 year later, she presented again with markedly dilatated and reduced right heart function caused by degeneration of both biologic valves...

Transcatheter pulmonary valve implantation (TPVI) within a failed bioprosthetic valve is safe and effective Coronary artery compression is a potential risk, requiring careful preimplantation balloon dilation testing Prestenting is required for TPVI in stentless conduits Improvements in right ventricular volume, pressure, pulmonary stenosis, and regurgitation can be maintained in the intermediate term Long-term risk for Melody valve endocarditis and valve dysfunction necessitates careful monitoring.

With new surgical techniques, more and more complex congenital heart defects are treated requiring sometimes right ventricle to pulmonary artery conduit implantation. In order to extend RV to PA conduit lifespan, 15 years ago a valved stent was developed. The implantation technique was progressively standardized to decrease risks of procedural complications. Medium and long-term hemodynamic results of the stent were so good that indications were broadened to native or complex right ventricular outflow tracts...

REVIEW
Elżbieta K Biernacka, Witold Rużyłło, Marcin Demkow
Percutaneous pulmonary valve implantation (PPVI) is a relatively new method of treating patients with right ventricular outflow tract (RVOT) dysfunction after surgical repair of congenital heart disease. Since its introduction in 2000 by Bonhoeffer, more than ten thousand PPVI procedures have been performed worldwide. Indications for PPVI have been adapted from those accepted for surgical intervention. Two types of valves are being used: Melody Medtronic available in diameters 16 mm and 18 mm and the family of Edwards SAPIEN valves 23, 26 and 29...

Some patients with pulmonary valve stenosis do not respond to balloon valvuloplasty and must undergo surgical repair. We report the case of a 12-year-old child with pulmonary valve stenosis and Noonan syndrome in whom we performed transcatheter Melody pulmonary valve implantation after balloon dilation failed. The result was excellent. This technique can be proposed as an alternative to surgery in such cases.

Infective endocarditis is a serious complication occurring after percutaneous pulmonary valve replacement with a Melody valve; it is of uncertain incidence, and presents a challenging diagnosis. Vegetations may be difficult to visualise with transthoracic and transoesophageal echocardiography. We report the role of intracardiac echocardiography in this condition by confirming the prosthesis involvement.

OBJECTIVES: To define the optimal timing for percutaneous pulmonary valve implantation (PPVI) in patients with severe pulmonary regurgitation (PR) after Fallot's Tetralogy (ToF) correction. BACKGROUND: PPVI among the aforementioned patients is mainly driven by symptoms or by severe right ventricular (RV) dilatation/dysfunction. The optimal timing for PPVI is still disputed. METHODS: Twenty patients [age 13.9 ± 9.2 years, (range 4.3-44...

OBJECTIVES: This study compared the risk of infective endocarditis (IE) after percutaneous pulmonary valve implantation (PPVI) with the Sapien and Melody valves. BACKGROUND: The incidence of IE after PPVI is estimated at 3% per year with the Melody valve. The Sapien valve is a more recently marketed valve used for PPVI. METHODS: We retrospectively included consecutive patients who underwent PPVI at a single center between 2008 and 2016. IE was diagnosed using the modified DUKE criteria...

Percutaneous pulmonary valve implantation (PPVI) has become a widely practiced treatment option for patients with right ventricular outflow tract (RVOT) dysfunction. For this procedure, the Melody transcatheter pulmonary valve has become the most widely used system. On-label indications are limited to the treatment of failing circumferential conduits. However, there is growing but still limited experience with the off-label treatment of native or patched RVOTs. Here, the case is reported of a 57-year-old patient in whom redo-surgery for a dysfunctional pulmonary valve could be avoided by PPVI into the patched RVOT at 51 years after tetralogy of Fallot repair...

BACKGROUND: Transcatheter pulmonary valve implantation (TPVI) with the Melody® transcatheter pulmonary valve (TPV) has demonstrated good haemodynamic and clinical outcomes in the treatment of right ventricular outflow tract (RVOT) conduit dysfunction in patients with repaired congenital heart disease CHD. We present the first Australian single centre experience of patients treated with Melody TPV. METHOD: A prospective, observational registry was developed to monitor clinical and haemodynamic outcomes in patients with RVOT dysfunction treated with the Melody TPV (Medtronic Inc, Minneapolis, United States)...
