BACKGROUND: Stenting of stenotic right ventricular outflow tract is a palliative measure for severely impaired small babies with Tetralogy of Fallot or similar pathologies. Little is known about the histopathological fate of the stents in the right ventricular outflow tract. METHODS: Eight samples of surgically removed right ventricular outflow tract stents were histologically analysed according to a predefined protocol. RESULTS: The most frequent diagnosis was Tetralogy of Fallot in four patients, pulmonary atresia with ventricular septal defect in two patients, double outlet right ventricle with pulmonary obstruction in one patient, and muscular obstruction of the right ventricular outflow tract in one patient with a syndromic disease with hypertrophic cardiomyopathy...

Performance of cardiovascular magnetic resonance (CMR) in the planning phase of percutaneous pulmonary valve implantation (PPVI) is needed for the accurate delineation of the right ventricular outflow tract (RVOT), coronary anatomy and the quantification of right ventricular (RV) volume overload in patients with significant pulmonary regurgitation (PR). This helps to find the correct timings for the intervention and prevention of PPVI-related complications such as coronary artery compression, device embolization and stent fractures...

Management of pulmonary atresia, ventricular septal defect with major aorto-pulmonary collateral arteries, and hypoplastic native pulmonary arteries focuses on growth of the native pulmonary arteries. One strategy to grow the native pulmonary arteries is through pulmonary valve perforation followed by right ventricular outflow tract stenting, if suitable. We present a unique case of retrograde pulmonary valve perforation and stenting of the right ventricular outflow tract through a major aorto-pulmonary collateral artery...

The implantation of percutaneous balloon expandable valves in native or patched right ventricular outflow tracts (nRVOT) is a challenging technique due to the diversity of anatomies and shapes, the large sizes, and the distensibility of the nRVOT, for which specific techniques have been developed. We present a single center experience with balloon expandable percutaneous pulmonary valves in nRVOT, describing the techniques used, complications observed, and a short-mid term follow-up.. This is a single center descriptive study of patients who underwent a percutaneous pulmonary valve implantation in a nRVOT with a balloon expandable pulmonary valve in our center between September 2012 and June 2022...

BACKGROUND: Transcatheter valve replacement is a less invasive alternative to surgical valve replacement and has become increasingly popular. It is often the preferred approach for patients with high surgical risk. In patients with multiple prior sternotomies and multi-valvular failure, sequential transcatheter valve replacements may be a viable option. CASE SUMMARY: We present the case of a 61-year-old-man with two prior sternotomies who underwent sequential transcatheter replacements of the aortic and pulmonic valves for symptomatic aortic and pulmonary stenosis...

BACKGROUND: Pulmonary valve replacement is recommended in patients with repaired tetralogy of Fallot based on cardiac magnetic resonance imaging (MRI) criteria. This procedure is performed by surgical or transcatheter approaches. OBJECTIVE: We aimed to investigate the differences in preprocedural MRI characteristics (volume, function, strain) and morphology of the right ventricular outflow tract and branch pulmonary arteries in patients for whom surgical or transcatheter pulmonary valve replacement was planned...

Pulmonary atresia with intact ventricular septum (PAIVS) is a rare congenital heart disease that often needs a critical decision on whether to open the right ventricular outflow tract (RVOT). Significant morbidity and considerable mortality might preclude the safe use of percutaneous or surgical right ventricular decompression in patients with muscular PAIVS. We report the case of a 21-day-old neonate weighing less than 3 kg who underwent hybrid RVOT stent insertion as initial palliation for muscular PAIVS and subsequent anatomical correction at 5 months of age, with 6 years of follow-up...

Significant pulmonary regurgitation (PR) and pulmonary stenosis are common after surgical repair of some congenital heart defects. This prospective, single-arm, multicenter trial enrolled patients who underwent transcatheter heart valve (THV) implantation with a SAPIEN 3 valve to treat dysfunctional right ventricular outflow tract (RVOT) conduits or pulmonic surgical valves (≥ moderate PR and/or mean RVOT gradient ≥35 mm Hg). The primary end point was a nonhierarchical composite of THV dysfunction at 1 year comprising RVOT reintervention, ≥ moderate total PR, and mean RVOT gradient >40 mm Hg...

A woman in her 60s presented with progressive exertional dyspnoea, exertional chest pressure and exertional dizziness. Echocardiogram identified a 156 mm Hg left ventricular outflow tract gradient with provocation, indicating hypertrophic cardiomyopathy with left ventricular outflow obstruction-confirmed with MRI and angiogram. An alcohol septal ablation was planned but due to communication of the second septal perforator with the right ventricle and a wire-induced mid-left anterior descending artery dissection, alcohol septal ablation was not performed...
