Introduction: Right thoracotomy is a well known alternative
for mid-sternotomy to have access to the left atrium. To avoid
the potential drawbacks asssociated with sternotomy coupled to
the desire for a smaller scar and fast rehabilitation, led us
to investigate the video-assisted mitral valve surgery through
Port-Accessapproach.
Patients and methods: From February 1997 until July 2000,
163 consecutive patients (90 M/73 F), had either Port-Access
mitral valve repair (n=106) or replacement (n=56) for degenerative
disease (n=108), rheumatic disease (n=36), chronic endocarditis
(n=11), annular dilatation (n=8). Standard Carpentier repair procedures
were used in all patients; 19 patients has PTFE chordae for anterior
leaflet prolaps.
Results: Hospital mortality was 1,7 % (n=3). Four patients
had conversion to sternotomy and conventional CPB for aortic dissection.
Mean cross clamp time and perfusion time was 98 minutes (24-160)
and 137 minutes (75-215) respectively. Cerebro-vascular or periphereal
ischaemia due to thrombo-embolic phenomena or wound complications
were not seen. High degree of satisfaction was obtained in all
patients.
Conclusion: The video-assisted Port-Access mitral valve
approach is a valid alternative to sternotomy with the same standards
of results and quality.
