AIMS: Paediatric patients with mitral valve (MV) disease have limited options for prosthetic MV replacement. Based on a long experience with the stented bovine jugular vein graft (Melody Valve) in the right ventricular outflow tract, we tested the use of the Melody Valve as a surgical implant in the mitral position in patients with congenital mitral disease. METHODS AND RESULTS: Eight patients, age 3 months to 6.2 years, with congenital MV dysplasia had undergone Melody valve implantation in mitral position between March 2014 and October 2015...

BACKGROUND: Tetralogy of Fallot with cyanosis requiring surgical repair in early infancy reflects poor anatomy and is associated with more clinical instability and longer hospitalization than those who can be electively repaired later. We bridged symptomatic infants with risk factors for early primary repair by right ventricular outflow tract stenting (stent). METHODS AND RESULTS: Four groups of tetralogy of Fallot with confluent central pulmonary arteries were studied: stent group (n=42), primary repair (aged <3 months) with pulmonary stenosis (early-PS group; n=44), primary repair (aged <3 months) with pulmonary atresia (early-PA group; n=49), and primary repair between 3 and 11 months of age (surg>3mo group; n=45)...

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...

OBJECTIVES: The aim of this study was to identify predictors of permanent pacemaker implantation (PPMI) following transcatheter aortic valve replacement (TAVR) with a balloon-expandable transcatheter valve (Edwards SAPIEN 3). BACKGROUND: New-onset conduction disturbances requiring PPMI remain a major concern following TAVR. Predictors are not yet well defined. METHODS: The influence of angiographic implantation depth, device landing zone calcium volume, oversizing, pre- and post-dilation, and baseline conduction disturbances on PPMI rate was analyzed in 229 patients undergoing TAVR with the SAPIEN 3 device...

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...

BACKGROUND: Transcatheter pulmonary valve replacement (tPVR) is an accepted therapy for treatment of dysfunctional right ventricular outflow tract (RVOT) conduits. At present, the majority of Fallot patients who undergo transannular patch (TAP) repair are not candidates for tPVR due to the large irregular nature of their RVOT. Herein, we describe a novel approach to assessing the RVOT in this group, which may then be used to design, test, and carry out hybrid RVOT modification and transcatheter valve implantation in this population...

BACKGROUND: Echocardiographic calculation of effective orifice area (EOA) after transcatheter aortic valve replacement is integral to the assessment of transcatheter heart valve (THV) function. The aim of this study was to determine the most accurate method for calculating the EOA of the Edwards SAPIEN and SAPIEN XT THVs. METHODS: One hundred intraprocedural transesophageal echocardiograms were analyzed. To calculate the post-transcatheter aortic valve replacement left ventricular outflow tract (LVOT) stroke volume (SV), four diameters were measured using two-dimensional echocardiography: (1) baseline LVOT diameter (LVOTd_PRE), (2) postimplantation LVOT diameter, (3) native aortic annular diameter, and (4) THV in-stent diameter...

BACKGROUND: Right ventricular outflow tract (RVOT) conduit dysfunction is a limitation of the Ross procedure. Transcatheter pulmonary valve replacement (TPVR) could alter the impact of conduit dysfunction and the risk-benefit balance for the Ross procedure. METHODS: Retrospective review of databases from 3 prospective Melody TPV (Medtronic Inc, Minneapolis, MN) trials. RESULTS: Among 358 patients who were catheterized with the intent to implant a Melody TPV for RVOT conduit stenosis or regurgitation (PR) as part of 3 prospective multicenter studies, 67 (19%) had a prior Ross procedure...

OBJECTIVE: Distortion of transcatheter heart valve (THV) stent shape and morphology has been shown to impact on THV function. This study sought to evaluate the relationship between geometrical CT follow-up data and consequent valve function in patients undergoing transcatheter pulmonary valve replacement with the Edwards SAPIEN THV. METHODS: All patients were enrolled in the COMPASSION trial. Multidetector computed tomography (MDCT) was performed as part of the study protocol at 6 months and yearly thereafter following valve implantation...

Aspergillus infections such as Aspergillus endocarditis were once relatively rare occurrences, however, due to the increased use of intracardiac devices, the incidence has grown. With mortality rates close to 100%, in medically treated cases, it is paramount that early diagnosis and treatment are performed. An immunocompetent aviculturist presented 8 months post aortic root replacement for severe aortic regurgitation with a composite graft, with central crushing chest pain. Investigations confirmed ST elevation inferior myocardial infarction due to stenosis of the origin of the right coronary artery, which was stented...
