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.

Garth Dixon, Georgi Christov
PURPOSE OF REVIEW: Infective endocarditis in children remains a clinical challenge. Here, we review the impact of the updated 2015 American Heart Association and European Society of Cardiology guidelines on management as well as the significance of the new predisposing factors, diagnostic and treatment options, and the impact of the 2007-2008 change in prophylaxis recommendations. RECENT FINDINGS: The new 2015 infective endocarditis guidelines introduced the endocarditis team, added the new imaging modalities of computer tomography and PET-computer tomography into the diagnostic criteria and endorsed the concept of safety of relatively early surgical treatment...

Spectral detector computed tomography (SDCT) is a novel technology that uses two layers of detectors to simultaneously collect low and high energy data. Spectral data is used to generate conventional polyenergetic images as well as dedicated spectral images including virtual monoenergetic and material composition (iodine-only, virtual unenhanced, effective atomic number) images. This paper provides an overview of SDCT technology and a description of some spectral image types. The potential utility of SDCT for cardiovascular imaging and the impact of this new technology on radiation and contrast dose are discussed through presentation of initial patient studies performed on a SDCT scanner...

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...

Transcatheter aortic valve replacement is standard of care for patients with severe aortic stenosis at high risk for surgical aortic valve replacement. Although not intended for treatment of primary aortic insufficiency, several transcatheter aortic valve prostheses have been used to treat patients with severe aortic insufficiency (AI), including patients with left ventricular assist devices (LVAD), in whom significant AI is not uncommon. Similarly, transcatheter valve replacements have been used for valve-in-valve treatment, in the pulmonary, aortic, and mitral positions, either via a retrograde femoral approach or antegrade transseptal approach (mitral valve-in-valve)...

Surgical and transcatheter interventions have seen a tremendous evolution in last three decades. Hybrid technology combines the achievements of both disciplines to bring substantial hemodynamic benefit to patients with congenital heart disease (CHD) in a minimally invasive manner. This collaboration between surgeons and interventionalists will continue to grow as the technology evolves to meet the demands of CHD patients, potentially avoiding cardiopulmonary bypass and vascular access complications as well as optimizing immediate technical outcomes with exit angiography...

OBJECTIVE: The use of a conduit is an established surgical method for reconstruction of the right ventricular outflow tract in congenital heart disease; however, its limited durability makes reintervention almost inevitable. We studied the trends in new implantation, reoperation, and transcatheter pulmonary valve replacement (TPVR) from a Swedish national perspective. DESIGN AND RESULTS: The Swedish registry of congenital heart disease (SWEDCON) was used to collect data...

The creation of a living heart valve is a much-wanted alternative for current valve prostheses that suffer from limited durability and thromboembolic complications. Current strategies to create such valves, however, require the use of cells for in vitro culture, or decellularized human- or animal-derived donor tissue for in situ engineering. Here, we propose and demonstrate proof-of-concept of in situ heart valve tissue engineering using a synthetic approach, in which a cell-free, slow degrading elastomeric valvular implant is populated by endogenous cells to form new valvular tissue inside the heart...

BACKGROUND: Transcutaneous pulmonary valve replacement (TPVR) has become an alternative to heart surgery for patients after previous right ventricular outflow tract (RVOT) or pulmonary artery (PA) surgical interventions. The objective was to present immediate and long-term outcomes of transcutaneous pulmonary valve replacement. METHODS: Between 06/2009 and 06/2016, 46 patients underwent TPVR. Initial diagnoses included tetralogy of Fallot, common arterial trunk, transposition of great arteries post Rastelli correction, left ventricle outflow obstruction after Ross operation, pulmonary atresia, and isolated dysplastic pulmonary valve stenosis...

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...

Transcatheter aortic valve implantation (TAVI) is currently the treatment of choice for patients with severe aortic stenosis (AS) who are unsuitable for surgical aortic valve replacement (SAVR), and is an acceptable alternative for those at high and intermediate surgical risk. In published TAVI registries and meta-analyses, whilst women are significantly older they present with fewer comorbidities compared to men (including coronary artery disease, peripheral vascular disease, diabetes and chronic obstructive pulmonary disease)...

Pulmonary regurgitation and/or stenosis (PS) is challenging in patients with congenital heart defects. Our aim was to identify if criteria for referral were different between surgical (SPVR) and transcatheter pulmonary valve replacement (TPVR) populations, and to further assess if any baseline differences influence the resultant ventricular remodeling at medium-term follow-up. Retrospective chart review of patients post-SPVR or TPVR at our center from 2013 to 2015 was conducted. Volumetric data from cardiac magnetic resonance (CMR), 1 year before and 1 year after PVR was obtained...

OBJECTIVES: Although transcatheter aortic valve replacement (TAVR) is an excellent alternative procedure for high-risk patients with severe symptomatic aortic stenosis, it is often associated with life-threatening complications. We report on the emergency or elective use of veno-arterial extracorporeal membrane oxygenation (ECMO) to manage these complications. METHODS: Between December 2013 and February 2016, 46 patients underwent TAVR at our institution. Of these, 4 patients required emergency ECMO support and another 3 patients were electively placed on ECMO support at the start of the procedure...

BACKGROUND: Right ventricular (RV) dysfunction was shown to be associated with adverse outcomes in a variety of cardiac patients and is considered a risk factor for adverse outcome according to the updated Valve Academic Research Consortium criteria. OBJECTIVE: Our goal was to assess the impact of RV function at baseline on 1-year mortality among patients with severe aortic stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR). METHODS: All patients with severe AS treated with TAVR from May 2007 to March 2015 at our center were included in the present study, and baseline and procedural characteristics were recorded for each patient...

Barry O'Brien, Haroon Zafar, Simon De Freitas, Faisal Sharif
In recent years, the transseptal puncture approach has enabled passage of increasingly large and complex devices into the left atrium. Traditional tools remain effective in creating and dilating the initial puncture, with an acceptable safety profile. Even for skilled operators, the procedure is technically demanding and requires sound understanding of atrial anatomy. Intracardiac echocardiography is useful in cases of previous septal repair, poorly defined fossa ovalis anatomy or when considering patent foramen ovale portal crossing...

Transcatheter aortic valve implantation is a recent innovation in the treatment of severe aortic stenosis. On the other hand, several reports suggested that minimally invasive aortic valve replacement (MICS-AVR) is likely to be associated with reduced postoperative discomfort and faster recovery. Of note, an upper partial sternotomy for isolated aortic valve replacement( L-shaped MICS-AVR) has been accepted as the most common approach to the MICS-AVR. Since October 2013, we have preformed L-shaped MICS-AVR at our hospital...
