ABSTRACT

A comunicação interatrial tipo ostium secundum (CIA OS) é uma cardiopatia congênita relativamente frequente, que causa repercussão hemodinâmica para o ventrículo direito, com sobrecarga volumétrica e dilatação da câmara. A maioria dos pacientes é assintomática, porém sintomas podem aparecer depois da segunda década de vida. O tratamento eletivo é usualmente realizado próximo ao quinto ano de vida, podendo ser indicado mais precocemente quando houver sintomatologia exuberante. O fechamento transcateter usando uma prótese de duplo disco é bem estabelecido como a primeira escolha de tratamento para a maioria dos pacientes de anatomia favorável. Foi comprovado que o forame oval patente (FOP) está associado à acidente vascular cerebral isquêmico (AVCI) em pacientes com poucos ou nenhum fator de risco de doença cardiovascular. Recentemente, foi demonstrado que a oclusão transcateter do FOP é superior ao tratamento clínico para prevenir recorrências de AVCI nessa população, em um estudo randomizado com acompanhamento clínico de longo prazo. Este manuscrito revisa as atuais indicações, critérios de seleção do paciente e o seguimento clínico dos pacientes com CIA OS e FOP submetidos ao tratamento transcateter


Ostium secundum atrial septal defect (OS-ASD) is a relatively frequent congenital heart defect that causes hemodynamic burden on the right ventricle with volume overload and chamber dilatation. Most patients are asymptomatic, however symptoms can appear after the second decade of life. Elective treatment is usually performed around the fifth year of life, and may be occasionally indicated earlier if there are exuberant symptoms. Transcatheter closure using a double disc device is well established as the first choice of treatment for most patients with suitable anatomy. Patent foramen ovale (PFO) has been shown to be associated with ischemic stroke in patients with no or limited risk factors for cardiovascular disease. It was recently demonstrated in a randomized trial with long-term follow-up that transcatheter closure of PFO is superior to medical treatment for preventing recurrences of stroke in this patient population. This manuscript reviews the current indications, patient selection criteria, and long-term follow-up in patients with OS-ASD and PFO submitted to transcatheter closure

ABSTRACT

INTRODUÇÃO: Uma nova geração de próteses Amplatzer com menor perfil e maior flexibilidade foi desenvolvida recentemente para o tratamento percutâneo da persistência do canal arterial (PCA). Neste artigo é relatado o uso desse novo dispositivo, Amplatzer Duct Occludder IITM (ADO II), para o tratamento tanto de PCA como de outros defeitos congênitos e estruturais, avaliando sua eficácia e segurança. Métodos: Estudo longitudinal observacional de um coorte de pacientes portadores de cardiopatias congênitas e estruturais tratados com ADO II entre outubro de 2009 e agosto de 2011. Pacientes com menos de 5 kg e canais > 5,5 mm e/ou do tipo B foram excluídos do estudo. A prótese foi implantada por vias anterógrada ou retrógrada. A cintura foi cerca de 2 mm maior que o defeito e o comprimento da prótese foi de 4 mm para lesões mais curtas ( até 6-8 mm). Resultados: Foram incluídos no estudo 28 pacientes, com mediana de idade e de peso de 2 anos e 11,7 kg, respectivamente, dos quais 23 eram portadores de PCA com diâmetro mínimo de 2,3 +- 0,8 mm. Os demais apresentavam...


BACKGROUND: A new generation of Amplatzer devices with lower profile and greater flexibility has been recently developed for percutaneous occlusion of the patent ductus arteriosus (PDA). In this paper, the use of this new device, the Amplatzer Duct Occludder II TM (ADO II) for percutaneous closure of the PDA as well as for the treatment of other congenital and structural heart defects is reported, assessing its safety and efficacy. METHODS: Longitudinal and observational study of a cohort of patients with congenital and structural heart defects treated with ADO II between October 2009 and August 2011. Patients weighing less than 5 kg and PDAs > 5.5 mm and/or type B were excluded. The device was implanted using the antegrade or retrograde approach. The waist was 2 mm larger than the defect and the length of the prosthesis was 4 mm for shorter lesions (less than 6-8 mm). RESULTS: Twenty-eight patients with a median age and weight of 2 years and 11.7 kg, respectively, were included. Twenty-three had a PDA with a mean minimal diameter of 2.3 + 0.8 mm. The remainder had muscular ventricular septal defect (1), pulmonary arteriovenous fistula (1), ruptured aneurysm of the sinus of Valsalva (1), and univentricular heart in the early postoperative period of bidirectional cavopulmonary anastomosis with residual antegrade pulmonary flow (2). The device was successfully implanted in all patients, except for an infant weighing 8 kg with a long, tortuous and oblique PDA with a diameter of 2.8 mm and a shallow ampulla. There was total occlusion of the defects in all patients. One patient with univentricular heart and right isomerism died due to complications not related to the procedure. CONCLUSIONS: ADO II proved to be a flexible, safe and effective device for the percutaneous treatment of infants, children and selected adults with PDA and other congenital and structural heart defects. Its use may have limitations for some anatomical PDA configurations in smaller infants.
