“…7,10,11,14,15 All of the surgical procedures were performed successfully with no postoperative reported complications and patients often reported the absence of the initial symptoms on regular follow-up. In 6 patients including the current case, a decision was made to medically treat the patient with a follow-up visit every 6 months, 8,9,12,[16][17][18] while there was no information regarding the faith of 3 patients from the same family reported by Kanagala et al 4 Although hypoplasia of the PML is an abnormality that is mostly present in infancy and childhood with symptomatic mitral regurgitation, 19,20 Left atrial enlargement and subsequent development of atrial fibrillation may hasten the process of annular dilatation. They reported this congenital anomaly as a consequence of developmental arrest at the stage of chordae and leaflets conversion from muscular to thin connective structures.…”

Hypoplasia of the mitral leaflets is rarely reported in adults. We reported a 45-year-old man presented to us with palpitation, dyspnea, and severe mitral regurgitation. In echocardiographic examination, an immobile hypoplastic posterior mitral leaflet (PML) was detected. A review of clinical and echocardiographic findings of all reported cases revealed that mitral regurgitation was the most common finding associated with PML hypoplasia/uni-leaflet mitral valve. PML hypoplasia is rare and often an incidental diagnosis during echocardiography, which could be relatively well tolerated since adulthood and carries a good prognosis.

“…. o presente estudo, em 100% dos pacientes acompanhados, mostrou sobrevida de 79,0 ± 17,7% em seis anos e 99,0% em cinco anos, satisfatória diante de 76% de sobrevida registrado por outros autores, nesse período 26, 38, É comum encontrar referências associando os procedimentos de valvoplastia a um índice superior de sobrevida, quando comparado à troca valvar 1, 21,32,34,36,38,40. No entanto, o índice de sobrevida ora apresentado (79%) é semelhante ao índice de 80,9% para a troca mitral com prótese de pericárdio bovino no mesmo período 6; é de notar diminuição do índice de reparo de 99% para 79% no quinto ano, com um óbito por AVC hemorrágico.…”

RESUMO : 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. DESCRITORES: valva mitral, plastia; próteses valvulares cardíacas, biológicas, cirurgia.

“…In our series, this occurred in 50% and has varied between 0 and 39.5% for associated congenital mitral regurgitation. [22][23][24] It is possible that the mitral valve may have been amenable to repair in patient 3, reducing this figure to 25%, had there not been avoidable delays in presenting for surgery. Rates of reoperation for mitral valve repair have ranged from 7 to 30%.…”
