[Open heart operation under videosurgery and minithoracotomy. First case (mitral valvuloplasty) operated with success].

The development of "less invasive surgery" using small incisions and videoscopic techniques may change, in the near future, our attitude towards "traditional" surgery. This is because of specific advantages such as skin limited incisions, reduced perioperative disability and lower cost. Up to now, only abdominal, thoracic and coronary artery surgery which do not imply the opening of the heart, or closure of simple atrial septal defects, have benefitted from this new approach. This article reports the first case of open heart surgery for complex lesions of the left heart through a minithoracotomy (5 x 4 cm) with the use of videotransmission and peripheral extracorporeal circulation. The patient, a 30-year-old female, was operated upon for a combined mitral valve stenosis and insufficiency of rheumatic origin unsuccessfully treated by a previous percutaneous valve dilatation. The 2.5 h open heart procedure comprised commissurotomy, repair of torn leaflets, chordal transposition and Carpentier-Edwards prosthetic ring implantation. The patient left the hospital 12 days after the operation. Transesophageal echocardiography at discharge showed normal valve function with no residual stenosis or residual leak.
