The reproducibility and reliability of mitral valve repair for bileaflet prolapse compares favorably with that of posterior leaflet prolapse. Early surgery might be recommended for patients with severe mitral regurgitation owing to bileaflet prolapse.

The postoperative Zva was significantly associated with LV mass regression after AVR. Maintaining low global LV afterload following AVR may enhance LV reverse remodeling.

Atopic dermatitis is a skin condition often complicated by colonization with Staphylococcus aureus, which increases the risk of infective endocarditis, skin cellulitis and osteomyelitis. Positive cultures for Staphylococcus aureus are obtained from 70% to 80% of wounds in patients with mediastinitis. Thus sternotomy carries increased risk of mediastinitis in patients with atopic dermatitis. We retrospectively reviewed 25 patients with atopic dermatitis who underwent cardiac surgery via a median sternotomy or thoracotomy from January 1997 to September 2010 at our institution. Postoperative mediastinitis due to methicillin-resistant Staphylococcus aureus was found in 3 patients who had a median sternotomy. They were ultimately discharged in good condition. No mediastinitis occurred in patients undergoing thoracotomy. Mediastinitis may occur due to direct exposure of the bone marrow to methicillin-resistant Staphylococcus aureus in patients with atopic dermatitis whose skin is colonized with such bacteria. Thoracotomy may be a better surgical approach in patients with atopic dermatitis who require thoracic surgery.
