title: Percutaneous mitral valvuloplastry in a pregnant woman guided only by the transesophageal echocardiography.
abstract: Mitral valve stenosis is the most common valve lesion in pregnancy. In spite of an optimized clinical treatment and a favorable valve anatomy according to Wilkins and Block score, in symptomatic patients, percutaneous intervention is shown to be of great importance. In these patients, avoiding x-ray exposure as much as possible is recommended so as to protect the fetus from the deleterious effects of ionizing radiation. In this case report, a 24-year old pregnant patient with severe mitral stenosis (valve area of 0.9 cm(2)) was successfully submitted to a TEE-guided percutaneous treatment, without the use of x-ray.
