Results: The surgical procedures were: plasty (n=20) or mitral valve replacement (n=36), aortic valve replacement (n=14), atrioseptoplasty using pericardial patch (n=32), tricuspid valve repair with rigid ring (n=6) and surgical correction of atrial fibrillation with radiofrequency (n=12). There were no complications during the procedures. There was no conversion to thoracotomy in neither case. Two patients developed atrial fibrillation in the postoperative period. There was an episode of stroke seven days after the hospital discharge and one death (0,9%) due to systemic inflammatory response syndrome (SIRS).Conclusion: This study demonstrates the coverage of pathologies that are possible to be approached by videoassisted cardiac surgery with cardiopulmonary bypass being a safe and effective procedure with low morbimortality. Minimally invasive video-assisted cardiac surgery is already a reality in Brazil, demonstrating excellent aesthetic and functional results. Rev Bras Cir Cardiovasc 2009; 24(3): 318-326 and transesophageal echocardiogram, ultrasound of the carotid arteries, abdominal, iliac and femoral arteries. In patients with suspicion of some obstruction of peripheral arteries, angiotomography of the thoracoabdominal aorta was requested. Special care was taken at the time of cardiac catheterization, avoiding puncturing the femoral vessels, giving preference to puncture of the radial artery and complete aortography was performed during the exam. After the first 40 cases, we included patients with an ejection fraction below 55%, emergencies, reoperations and obese patients.The age ranged from 18 to 68 years, and 57 patients were female (55.8%).

The use of minimally invasive technics in cardiac surgery has become widely discussed, aiming improvements not only in the aesthetics aspects but also better functional results. In this report, we present a case of a patient with severe mitral stenosis that underwent successful video-assisted minimally invasive mitral valve replacement.
