Abstract(s)
A regurgitaĆ§Ć£o mitral Ć© atualmente a anormalidade valvular mais frequente a nĆvel mundial, podendo ser aguda ou crĆ³nica. A presente monografia tem como objetivo fazer uma revisĆ£o da regurgitaĆ§Ć£o mitral crĆ³nica, focando-se essencialmente no seu tratamento.
A regurgitaĆ§Ć£o mitral crĆ³nica, se nĆ£o tratada, contribui para o aparecimento de disfunĆ§Ć£o sistĆ³lica e diastĆ³lica que por fim leva Ć insuficiĆŖncia cardĆaca.
A principal classificaĆ§Ć£o envolve a divisĆ£o em regurgitaĆ§Ć£o mitral primĆ”ria/orgĆ¢nica e secundĆ”ria/funcional.
A cirurgia Ć© o gold standard do tratamento da regurgitaĆ§Ć£o mitral primĆ”ria, mas apresenta resultados equĆvocos na regurgitaĆ§Ć£o mitral funcional. Nestes, a terapĆŖutica baseia-se essencialmente no tratamento mĆ©dico da insuficiĆŖncia cardĆaca e na terapia de ressincronizaĆ§Ć£o cardĆaca, ficando a cirurgia reservada para Ćŗltimo caso.
Contudo, muitos pacientes nĆ£o sĆ£o candidatos adequados Ć cirurgia. Um em cada dois pacientes nĆ£o pode ser operado em consequĆŖncia do risco cirĆŗrgico muito alto ou atĆ© mesmo proibitivo.
O desenvolvimento recente de tĆ©cnicas de reparaĆ§Ć£o minimamente invasivas por via percutĆ¢nea veio criar uma opĆ§Ć£o adicional para estes pacientes.
Mitral regurgitation is currently the most frequent valvular abnormality worldwide and may be acute or chronic. This monograph aims at reviewing chronic mitral regurgitation, focusing essentially on its treatment. Chronic mitral regurgitation, if left untreated, contributes to the development of systolic and diastolic dysfunction that ultimately leads to heart failure. The main classification involves the division into primary/organic and secondary/functional mitral regurgitation. Surgery is the gold standard for the treatment of primary mitral regurgitation, but presents equivocal results in functional mitral regurgitation. In these, the therapy is based essentially on the medical treatment of heart failure and cardiac resynchronization therapy, leaving the surgery reserved as a last resort. However, many patients are not suitable candidates for surgery. One in two patients cannot be operated as a result of very high or even prohibitive surgical risk. The recent development of minimally invasive percutaneous repair techniques has created an additional option for these patients.
