Repair of tetralogy of Fallot with atrioventricular septal defect may be associated with hemodynamic challenges in the postoperative period particularly as left atrial hypertension secondary to left atrioventricular valve dysfunction may exacerbate pulmonary regurgitation and augment low cardiac output. We present a case describing hybrid strategies to treat severe left atrioventricular and pulmonary valve regurgitation with modified balloon expandable stent valves to counter low cardiac output secondary to valve dysfunction...

Percutaneous therapies for congenital heart disease have been evolving rapidly despite limited investment from industry. The Melody transcatheter pulmonary valve (Medtronic, Inc, Minneapolis, MN USA) replacement therapy represents an important advancement in this arena. It has been approved in the United States for use in the pulmonary position, on a Humanitarian Device Exemption status. Off-label use of the Melody transcatheter pulmonary valve has extended to the mitral, pulmonary, and aortic valves, especially in previously implanted valves with prosthetic valve degeneration...

We report on successful endovascular retrieval of an accidentally flared Melody valve in an adult patient with an indication for percutaneous pulmonary valve implantation. The Melody valve was removed through a 24 F sheath, introduced via the right jugular vein, and the urgent open-heart surgery was avoided.

Narrow mitral annulus is a common situation faced in adult patients. Choice of prosthetic valve in such cases is unclear. There are reported experiences with supra-annular mitral valve, Manouguian technique, "Chimney technique" with mechanical valve and Melody valve, the latter two being in children. We report a novel "Bio-Chimney" technique in which a bioprosthetic valve of a size appropriate for the patient is sutured to a polyester vascular graft which is then implanted to the native narrow mitral annulus in an adult patient with promising initial results...

Nowadays, percutaneous pulmonary valve implantation (PPVI) is a suitable alternative to surgical procedure in patients with right ventricle outflow tract dysfunction. Two valves are currently available for PPVI: the Melody valve and the Edwards Sapien valve. The following complications may occur: coronary artery compression, deformation of the aortic root, stent or valve embolization, damage of distal pulmonary arteries, access site injuries. Here, we report on three cases of severe tricuspid regurgitation due to valvular and subvalvular apparatus damage during Edwards Sapien XT valve implantation...

BACKGROUND: Stented bioprosthetic valves (BPVs) are commonly used for surgical pulmonary valve (PV) replacement in postoperative congenital heart disease, but develop structural failure in a time-related fashion. The Melody transcatheter PV (TPV) (Medtronic, Minneapolis, Minn) has been used to treat BPV dysfunction, but there have been few studies in this population. METHODS: We performed a retrospective, multicenter study to evaluate Melody valve function in patients who underwent TPV replacement (TPVR) into a dysfunctional pulmonary BPV...

BACKGROUND: Transcatheter, bilateral branch pulmonary artery (PA) valve implantation is a novel treatment for patients with severe pulmonary insufficiency and oversized right ventricle (RV) outflow tract. There is scarce data on efficacy and safety of this approach. METHODS: This was a retrospective study of 8 patients with repaired tetralogy of fallot (TOF) who underwent bilateral branch PA valve implantation. Demographics, echocardiography, cardiac catheterization, and axial imaging data were reviewed...

BACKGROUND: Our institutional approach to tetralogy of Fallot (TOF) with major aortopulmonary collaterals (MAPCAs) emphasizes unifocalization and augmentation of the reconstructed pulmonary arterial (PA) circulation and complete intracardiac repair in infancy, usually in a single procedure. This approach yields a high rate of complete repair with excellent survival and low right ventricular (RV) pressure. However, little is known about remodeling of the unifocalized and reconstructed pulmonary circulation or about reinterventions on the reconstructed PAs or the RV outflow tract conduit...

OBJECTIVES: The aim of the study was to assess indications, procedural success, complications, echocardiographic, and clinical outcomes of percutaneous pulmonary valve implantation (PPVI) in adult patients with congenital heart disease (CHD). BACKGROUND: PPVI offers a non-surgical treatment option for failing prosthetic conduits in pulmonary position. However, efficacy and clinical outcomes after PPVI are still underreported. METHODS: From January 2008 to March 2016, 25 adult CHD patients with right ventricular outflow tract (RVOT) stenosis and/or pulmonary regurgitation underwent PPVI in our institution...

BACKGROUND: Since FDA approval of the Melody valve, transcatheter pulmonary valve replacement (TPVR) has been offered to an expanding population. Limited data exist regarding the safety and feasibility of TPVR in smaller patients. METHODS: All patients weighing <20 kg who underwent catheterization for percutaneous TPVR at four centers were reviewed. RESULTS: Of the 51 patients reviewed, 43 (84%) had successful valve implantation and 8 (16%) were found not to be candidates due to access veins too small (n = 3), coronary artery/aortic root compression (n = 3), and RVOT too large (n = 2)...

We present the surgical implantation in mitral position of the Edwards Sapien 3 valve for prosthetic valve endocarditis in a severely ill child after multiple valve replacements. The procedure was safely performed and provided adequate hemodynamic results in the short term. This report highlights the excellent potential of Sapien 3 valve for the treatment of mitral valve disease in children with a mitral valve annulus of appropriate size. Of note, the use of the Sapien 3 valve should be considered when a bioprosthesis is required at the time of valve re-replacement...

We sought to describe the acute results and short- to medium-term durability of transcatheter tricuspid valve-in-valve (TVIV) implantation within surgical bioprostheses among patients with Ebstein anomaly (EA). Cases were identified from a voluntary, multicenter, international registry of 29 institutions that perform TVIV. Demographic, clinical, procedural, and follow-up data were analyzed. Eighty-one patients with EA underwent TVIV from 2008 to 2016. Thirty-four patients (42%) were New York Heart Association (NYHA) class 3/4 at time of TVIV...

We present a case of successful bicaval Melody valve implantation to treat severe mitral regurgitation in a 44-year-old man with d-transposition of the great arteries, repaired via a Mustard operation. The patient sustained injury to the anterior mitral valve leaflet during laser extraction of a ventricular pacing lead resulting in acute, severe, symptomatic mitral regurgitation. The presence of systemic venous baffles of similar caliber to right ventricular outflow tract conduits allowed for implantation of Melody valves within each baffle...

Introduction Although the right jugular vein approach for percutaneous pulmonary valve implantation is well described, there are no reports that describe a percutaneous pulmonary valve implantation through a left superior caval vein to coronary sinus pathway. Case A 14-year-old female with tetralogy of Fallot, mesocardia, left superior caval vein draining into the coronary sinus, and hemiazygos continuation of the inferior caval vein underwent ventricular septal defect closure, with homograft insertion from the right ventricle to the pulmonary artery, patch augmentation of the left pulmonary artery, and creation of an atrial communication...

In this article we report the first case of Q fever endocarditis in a 13 years old child with a percutaneous pulmonary Melody(®) valve. The patient had a new onset of Melody valve dysfunction associated with the combination of hepatosplenomegaly and pancytopenia but was afebrile. Although blood cultures were negative, we have further investigated in the direction of infective endocarditis by performing PCR detection and the serology of C. burnetii which were positive. A combination antibiotic therapy with doxycycline and hydroxychloroquine was started with good clinical evolution...

OBJECTIVES: To describe a new modification, the one-step procedure, that allows interventionists to pre-stent and implant a Melody valve simultaneously. BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is the standard of care for managing patients with dysfunctional right ventricular outflow tract, and the approach is standardized. METHODS: Patients undergoing PPVI using the one-step procedure were identified in our database. Procedural data and radiation exposure were compared to those in a matched group of patients who underwent PPVI using the conventional two-step procedure...
