Clinical aspects
This is 41-year-old patient with a history of rheumatic disease who developed mitral stenosis and underwent mitral commissurotomy at age 36 due to the presence of incapacitating symptoms. In our country, the combination of mitral stenosis with rheumatic disease is quite common . About 25% of all patients with rheumatic disease have isolated mitral stenosis; 40% have double mitral dysfunction . The mean time interval between the initial acute onset and the appearance of symptoms can vary from a few to more than 20 years.
The presence of symptoms of heart failure (classes III and IV of the New York Heart Association), together with echocardiographic data that confirm significant anatomic lesion, is crucial for intervention indication: balloon valvuloplasty or surgery (commissurotomy or valve replacement). Whenever possible, there is an attempt to correct the valve defect, keeping the patient’s valve system, postponing prosthesis implantation. In this case, commissurotomy was performed, which maintained the patient well for approximately five years, when she started to present symptoms again, when mitral valve repair was performed. This evolution in the rheumatic patient can occur due to repeated episodes of valvulitis, hence the need to maintain secondary prophylaxis with benzathine penicillin in patients with cardiac involvement, preferably throughout life or up to the fifth decade, when it is not possible .
