This paper focus on the most common used prosthesis for replacement of diseased heart valves, when repair is not feasible. A brief historical review is made. New prosthesis and the trends for the future are also addressed.
The introduction of new procedures in surgery usually implies the costs of the so called learning curve. However patients should not suffer the negative effects of surgeon's learning curves. We report our results with the first 15 Ross procedures, a single surgeon and institution experience, and how it was possible to build a safe learning curve without major consequences for the patients. We emphasize the need for a continuous program of surgical performance assessment throughout the learning curve period, as was demonstrated in our series.
Primary sarcoma of the heart is a rare disease that has an ominous prognosis with either medical or surgical therapy. We report a case of a 25-year-old woman with sarcoma of the heart who received a transplant and is clinically well after 7 years. We believe that transplantation must be considered in this kind of pathology for selected cases.
A utilização do catéter de Foley na prática da algaliação está desde há muito definida. Os autores têm, no entanto, utilizado o catéter Foley em diversas situações de recurso, no âmbito da cirurgia cardíaca. A utilização deste método de enorme simplicidade e de muito baixo custo representa um verdadeiro "ovo de Colombo" e deve fazer parte do armentarium cirúrgico alternativo de cada um de nós. Descreve-se o uso do catéter Foley, como alternativa de recurso, nas seguintes situações: 1. Laceração de uma cavidade cardíaca na re-esternotomia com hemorragia catastrófica; 2. Realização de anastomoses proximais em aortas que não devem ou podem ser clampadas (calcificações extensas); 3. Realização de anastomoses de condutos ventrículo-direito artéria pulmonar com o coração a bater.
BACKGROUND: Valve surgery in children is aimed at restoring correct hemodynamics with few reoperations and limited resort to prostheses, which would imply early deterioration or definitive hypocoagulation. OBJECTIVES: Report a series of paediatric pts with acquired mitral valve disease, mostly due to rheumatic disease, in whom it was possible, for the great majority, to repair the damaged valve. DEMOGRAPHICS: Fifty children with predominant mitral valve disease, 47 rheumatic (94%) and 3 after endocarditis were consequently operated by the same surgical team over the last five years. Ages were 12.5+/-3.1 yrs and weights 33.2+/-8.4 Kg, 30 pts presented with predominant mitral regurgitation and 20 pts had significant stenosis. In 8 pts there also moderate to severe aortic regurgitation and in 2 pts severe tricuspid regurgitation was pres...
OBJECTIVES: Atrio-ventricular septal (AVSD) defects include a variable spectrum of congenital malformations with different forms of clinical presentation. We report the surgical results, from a single institution, with this type of congenital cardiac malformation. Patients with hypoplasia of one of the ventricles were excluded from this analysis. POPULATION: Between November of 1998 and June of 2005, 49 patients with AVSD were operated on by the same team and in the same department. The average age was 37.3 months (medium 6 months) and 31 patients were female. In 38 patients (78%) an inter-ventricular communication was present (AVSD-complete) and of these, 26 were of the type A of Rastelli, being 13 of type B or C. The age for defect correction of the complete form was of 5.5 months, palliative surgery was not carried out on any of th...
The Ross procedure has been used in children and young adults for aortic valve replacement and the correction of complex obstruction syndromes of the left ventricular outflow tract. We report the mid-term results of the Ross procedure in a single institution and performed by the same surgical team. Population: Between March 1999 and December 2005, 18 patients were operated on using the Ross procedure. The mean age at the time of surgery was 12 years, being 12 patients male (67%). The primary indication for surgery was isolated aortic valve disease, being the predominant abnormality in 58% of cases aortic regurgitation and in 42% left ventricular outflow tract obstruction. Associated lesions included sub-aortic membrane in 3 patients (16%), small VSD in 2 patients (11%), bicuspid aortic valve in 4 patients (22%) and severe left ventricu...
A presença de trombos móveis na aurícula direita são fenómenos raros, mas associados a uma elevada mortalidade. Apesar de a ecocardiografia ter permitido avanços no seu diagnóstico, a sua abordagem continua a ser motivo de debate. Neste artigo apresentamos o caso de uma doente do sexo feminino, de 24 anos, com antecedentes de tabagismo, obesidade e sob terapêutica anovulatória que recorre ao serviço de urgência por cansaço fácil e tosse com expetoração hemoptoica. O ecocardiograma transtorácico revelou massa, móvel, multilobulada de grandes dimensões na aurícula direita, condicionando abertura da válvula tricúspide. Perante episódios recorrentes de embolia pulmonar, foi submetida a cirurgia cardíaca com exérese da massa, sendo o resultado anatomopatológico compatível com trombo organizado com calcificação. O estudo genético revelou hom...
Isolated anterior mitral leaflet cleft (not associated with atrio-ventricular septal defect) is a rare cause of congenital mitral regurgitation, and the treatment consists of direct suturing of the cleft. We present a clinical case with this entity.
