“…Our study confirms previous findings [4,6,[8][9][10][11][12]17,181 that infundibular obstruction occurring immediately after BPV is a dynamic process that regresses during the follow-up period (up to 2 years). In several of these former studies, patients were treated with betaadrenergic blockers after BPV [8,9,11,15].…”

“…The indirect evidence was demonstrated by either sustained improvement in functional class and/or electrocardiographic regression/ normalization of right ventricular hypertrophy. Other investigators [ 11,12,14,15] have found similar electrocardiographic changes after BPV, reflecting sustained relief of right ventricular pressure overload. In addition, we noted that the majority of electrocardiographic improvement occurred within the first 6 months.…”

This report describes a new balloon pulmonary valvuloplasty technique using the Inoue balloon catheter performed in 14 consecutive adult patients, aged 17-47 years (mean 27). The mean right ventricular systolic pressure and the pulmonary valvular peak-to-peak systolic gradient decreased from 102 +/- 41 to 52 +/- 19 mm Hg (p = 0.001) and 81 +/- 40 to 7 +/- 7 mm Hg (p = 0.0002), respectively. An infundibular peak-to-peak systolic gradient either developed (n = 13) or increased (n = 1). None of the patients were treated with beta-adrenergic blockers before or after the valvuloplasty. Eight patients underwent repeat hemodynamic study 12-30 months (mean 17) after treatment, and had no evidence of valvular restenosis. The mean right ventricular systolic pressure and the mean infundibular peak-to-peak systolic gradient decreased, compared to the values immediately after valvuloplasty (54 to 40 mm Hg, p = 0.03, and 28 to 10 mm Hg, p = 0.03, respectively). The study suggests that pulmonary valvuloplasty in adults using the Inoue balloon catheter technique is feasible, safe, and effective.

“…Soon after the introduction of balloon pulmonary valvuloplasty for PVS by Kan et al in the USA, the number of patients treated by this method grew rapidly in many centres in South America, especially in Brazil and Argentina 34353637. Dr Fontes et al have demonstrated that the infundibular hypertrophy, commonly present in the more severe cases, usually regressed after the valvar obstruction was relieved 38.…”

Congenital heart diseases are one of the most common structural defects present at birth, with an approximate incidence of 8 per 1000 live births. As most countries in South America have a high birth rate, they are a significant public health concern. This paper provides a brief overview of the burden of congenital heart disease in South America, focusing on its local prevalence, facilities for treatment and outcomes after medical, surgical or catheter intervention for the most common diseases.

“…Valva pulmonar A técnica, introduzida por Kan em 1982 3 , ganhou rápida aceitação clínica e hoje é o método de escolha para o tratamento da estenose pulmonar valvar (EPV), substituindo a abordagem cirúrgica 1,5,[10][11][12][13] . O procedimento está indicado quando há gradiente sistólico máximo entre o ventrículo direito e o tronco da artéria pulmonar superior a 50 mmHg e na estenose pulmonar crítica do neonato e do pequeno lactente 14 .…”

“…O procedimento está indicado quando há gradiente sistólico máximo entre o ventrículo direito e o tronco da artéria pulmonar superior a 50 mmHg e na estenose pulmonar crítica do neonato e do pequeno lactente 14 . Os resultados são excelentes quando a abertura valvar é cêntrica, os folhetos assumem configuração cupuliforme na sístole, o anel pulmonar é normodesenvolvido e quando não há displasia valvar 5,6,[10][11][12][13] . As complicações são pouco freqüentes.…”

Objective: Cardiac catheterization has begun to be employed for therapeutic purposes since the middle sixties. In this paper the authors review the current indications, technique and results related to each of the interventional procedures. It also includes a brief sample of the Instituto "Dante Pazzanese" experience for illustrative purpose.Methods: The main procedures that are addressed include balloon and blade atrial septostomy (Rashkind and Park procedures), pulmonary valvuloplasty, aortic valvuloplasty, mitral valvuloplasty (for rheumatic mitral stenosis), angioplasty for coarctation of aorta with or without stent implantation, angioplasty for pulmonary artery stenosis with or without stent implantation, percutaneous occlusion of the patent ductus arteriosus, percutaneous occlusion of atrial septal defects and balloon dilation of stenosed Blalock-Taussig shunts. The authors make a review of the most important papers published in the literature about Interventional Pediatric Cardiology, including their own experience.Results: Good or excelent therapeutic results are achieved for pulmonic stenosis, coarctation of aorta, patent ductus arteriosus, atrial septal defects and pulmonary branch stenosis. Satisfactory palliations are obtained for aortic stenosis, rheumatic mitral stenosis and complex congenital heart diseases that require balloon atrial septostomy.Conclusions: Due to the recent technological development, pediatric therapeutic heart catheterization makes it possible to treat or palliate about 30% of all congenital or acquired heart diseases with encouraging results, sparing some patients from the need of cardiac surgery. ResumoObjetivo: A partir de meados da década de sessenta o cateterismo cardíaco passou a ter também uma finalidade terapêutica. Neste artigo os autores se propõem a revisar as indicações atuais, a técnica e os resultados relativos a cada procedimento intervencionista, incluindo também uma pequena casuística do Instituto "Dante Pazzanese" de Cardiologia, que é apresentada para fins ilustrativos.Métodos: São abordados principalmente a atrioseptostomia por cateter balão de Rashkind e por lâmina de Park, a valvoplastia pulmonar, a valvoplastia aórtica, a valvoplastia mitral na estenose mitral de origem reumática, a aortoplastia por cateter balão na coartação de aorta com e sem o implante de stents, a angioplastia da artéria pulmonar com e sem o implante de stents, a oclusão percutânea do canal arterial, a oclusão percutânea da comunicação interatrial e a dilatação de shunts de Blalock-Taussig estenóticos. Os autores fazem uma revisão bibliográfica dos trabalhos mais marcantes publicados na literatura sobre o tema cateterismo terapêutico em cardiologia pediátrica, incluindo sua própria experiência.Resultados: Resultados terapêuticos bons ou excelentes são obtidos para estenose pulmonar, coartação de aorta, persistência do canal arterial, comunicação interatrial e estenose de ramos pulmonares. Paliações satisfatórias são obtidas para estenose aórtica, estenose mitral reumática e c...
