          Abstract

          Foram estudados 101 pacientes submetidos a plástica da valva mitral em seis anos, com seguimento de 100%. Entre eles, 36 eram do sexo masculino e 65 do sexo feminino, com idade variando de dois a 62 anos (M = 28 ± 16,4). Desses, 57 (56,4%) foram submetidos apenas a abordagem valvar mitral. Os demais foram submetidos a procedimentos associados, como plástica tricúspide (9,9%), revascularização do miocárdio (4,0%), entre outros. Não foi registrado óbito imediato. O índice de mortalidade tardia foi de 2% (AVC hemorrágico após cinco anos e septicemia), no primeiro ano. As complicações não fatais foram representadas pela endocardite evidenciada em dois pacientes (2%), sendo tratados e curados, e um paciente com reestenose mitral pós-plástica por reagudização da doença reumática. O estudo atuarial revelou um índice de 79,0 ± 17,7% de sobrevida, um total de 76,3 ± 17,8% de pacientes livres de complicações, 80,0 ± 17,9% de reoperações, 100,0% livres de tromboembolismo. Os resultados ecodoplercardiográficos registraram que 89% dos pacientes evoluíram com ausência de insuficiência. Dos 11% restantes, 7,4% apresentram insuficiência mitral discreta, 2,4% moderada e 2% importante. De acordo com a classificação da NYHA, os pacientes das classes III (83,8%) e IV (16,2%) passaram para as classes I (33,3%), II (60,6%), III (4,1%) e IV (2%). Os autores concluem que o anel de pericárdio flexível conforma-se perfeitamente com o anel valvar, não produz hemólise e se endoteliza completamente a médio prazo.

          A hundred-and-one patients were studied in six years, with 100% of follow-up. Among them, 36 were male and 65 female, with an age range of two to 62 years (mean 28 ± 16.4%). Fifty seven of them (56.4%) underwent just a mitral surgery, the others and other associated procedures, as tricuspid plastic (9.9%), coronary artery revascularization (4.0%), among others. Hospital mortality was not registered. The late mortality rate was 2% for AVC hemorrhagic after five years, and septicemia during the first year. The non-fatal complications were represented by endocarditis in two patients (2%), treated and cured; and a mitral restenosis after plastic. The actuarial study revealed a survival rate of 79.0 ± 17.7% and rates of without complications, reoperation and thromboembolism of 76.3 ± 17.8, 80.0 ± 17.9 and 100%, respectively. The echocardiography results registered 89% of the patients with evolution to absence of insufficiency from the remaining 11%, 7.4% showed discrete mitral insufficiency, 2.4% moderate and 1.2% important. Under the NYHA classification, the patients functionally went from class III (83.3%) and IV (16.2%) to class I (33.3%), II (60.65), III (4.1%) and IV (2.0%). The authors conclude that the pericardium ring is flexible, it fits perfectly in the valvar ring, does not cause hemolysis, and shows completely endotelization after a certain time.

              Long-term evaluation of bioprosthetic valves: 615 consecutive cases.

              From January 1975 to September 1983, 615 patients underwent valve replacement using 698 bioprosthetic valves for selected indications. This group represents the third of all patients having valve replacement during the same period. Children younger than 15 years were excluded. The mean pre-operative functional class was 2.9. The early mortality rate was less than 5% and the follow-up range 3 months to 9 years (3.2 yrs). The symptomatic improvement was attested by a mean post-operative functional class of 1.4. In a linear study the following rates of valve related complications were noted: thromboembolism 4.6%, endocarditis 2.5%, primary tissue valve degeneration 1.1%, paraprosthetic leak 2.5%. In an actuarial study, at 8 years, 83% of patients were free from any valve failure. The probability rates of complications were the following: thromboembolic events 8%, endocarditis 5%, degeneration 3%, reoperation 7%. The probability of survival at 8 yrs was 69% and the probability rates of late mortality were noted as follow: cardiac related mortality 27%, valve-related mortality 4%. Despite an expected increasing rate of degeneration, the results warrant the use of bioprostheses in a selected group of patients.
