RESUMO

Rigorous clinical trials have demonstrated the safety and efficacy of Transcatheter Edge-to-Edge Repair to treat severe secondary mitral regurgitation (MR) in adults with primary cardiomyopathy who have failed guideline-directed medical therapy, as well as those with primary MR at high surgical risk. To date, there are only three case reports describing this procedure in the pediatric population. We report a case series of four pediatric patients, including the youngest and smallest reported, who underwent this procedure.

RESUMO

Surgical treatment of tetralogy of Fallot (TOF) involves surgical relief of right ventricular outflow tract (RVOT) obstruction and closure of ventricular septal defect. However, some patients may require staged palliation before surgical repair. This traditionally was achieved only with surgery but recently evolved to include catheter-based techniques. RVOT dysfunction occurs inevitably after the surgical repair of TOF and, depending on the surgical approach, manifests as either progressive stenosis, regurgitation, or a combination of both. This predisposes the individual to repeated RVOT interventions with the attendant risks of multiple open-heart surgeries. The advent of transcatheter pulmonary valve replacement has reduced the operative burden, and the expansion of transcatheter pulmonary valve replacement device platforms has widened the type and size of RVOT anatomies that can be treated. This review will discuss the transcatheter therapies available throughout the lifespan of the patient with TOF.


Les traitements chirurgicaux de la tétralogie de Fallot (TF) comprennent la correction de l'obstruction de la voie de chasse du ventricule droit (VCVD) et la fermeture de la malformation du septum interventriculaire. Toutefois, chez certains patients, une palliation par étapes doit être entreprise avant la correction chirurgicale. Cette palliation était autrefois réalisée par des interventions chirurgicales, mais des techniques de cathétérisme interventionnel sont récemment apparues. La dysfonction de la VCVD survient inévitablement après une correction chirurgicale de la TF et peut se manifester par une sténose progressive, une régurgitation ou les deux, selon l'approche chirurgicale utilisée. Les personnes qui vivent avec la TF sont ainsi susceptibles de subir plusieurs interventions à cœur ouvert et d'être exposées aux risques que cela comporte. L'arrivée de la valvulation pulmonaire percutanée (VPP) a permis de réduire le fardeau chirurgical, et la multiplication des plateformes pour les appareils de VPP rend possible le traitement d'une plus grande diversité d'anomalies de la VCVD. Notre article de synthèse présente les traitements par cathétérisme interventionnel qui peuvent être offerts aux patients atteints de TF au fil de leur vie.
