Mitral Valve Surgery Using a Modified Superior Left Atrial Approach.
Most surgeons use a longitudinal right lateral left atrial incision behind the inter-atrial groove for the exposure of the mitral valve, even though several other surgical techniques have been described. The shortest route to the mitral valve is, however, through the roof of the left atrium, where the incision is closest to the mitral annulus. This was first described by Meyer et al., but the approach became unpopular because of its technical difficulties and inadequacies. We have modified this technique, making it safer, easier and adaptable to any type of mitral surgery. We describe our experience with 53 patients who had mitral valve surgery using this modified approach. All of the operations were performed by the same surgeon over an 18 month period with consistently satisfactory results.
