The
development of new cardiopulmonary bypass technologies, special surgical
instruments, as well as intrathoracic visualization systems have facilitated
mitral surgery via a right small thoracotomy.
Since September 1996, 84 patients (39 male and 45 female) underwent minimally
invasive mitral valve surgery at our department. Mean age was 58.1 ± 8.2 years.
In 24 patients the Port-AccessTM system with an endoaortic balloon
clamp was used, 20 patients had video-assisted surgery with a transthoracic
aortic crossclamp. 28 mitral valves were replaced, 56 underwent repair. In 48
cases a complex mitral valve procedure was performed. Mean length of incision
was 7.0 ± 1.2 cm. Mean operating time amounted to 249 ± 32 min, mean bypass
time 148 ± 29 min, mean crossclamp time 94 ± 24 min.
Despite initially longer operating and cardiopulmonary bypass time clinical
outcome and postoperative valve function were good even in complex cases. The
transthoracic clamping technique is easier to perform, and avoids the specific
risks associated with the Port-AccessTM method. The cosmetic results
are excellent and the risk of wound infection is reduced. Up to now improved
recovery during hospital stay has not been proven.
