We employed vacuum-assisted closure (VAC) as a treatment modality for wound complications after cardiovasular surgery. Between March and December 2004, 9 patients were treated with VAC, 8 of whom were men, and the mean age was 69.6 years old. Seven patients underwent off-pump coronary artery bypass, and 2 underwent a valve replacement. Six of them had diabetes, 5 had renal dysfunction (4 were dialysis patients), and 2 had chronic obstructive lung disease. Six cases were classified as superficial sternal infection (Superficial) and 3 as a deep sternal infection (Deep). Superficial cases were healed with wound closure after a short period of VAC treatment. However, Deep cases required long duration of VAC treatment and wound closure with a myocutaneous flap in 2 cases, although all of them did not develop mediastinitis requiring closed irrigation and drainage. In 9 cases, with numerous risk factors for poor healing, we found that VAC treatment facilitated wound healing and reduced frequent painful wound care.

A 71-year-old man had been repeatedly admitted to our hospital with congestive heart failure, cerebral infarction and pneumonia. Under a diagnosis of mitral regurgitation and tricuspid regurgitation by echocardiography and catheter examination, mitral valve replacement and tricuspid annuloplasty were performed. Pathohistological study revealed a direct insertion of the papillary muscle into the anterior mitral leaflet (DPM) in addition to post-rheumatic valvular disease. These findings suggest that the increased rigidity of the scarring valve leaflets in combination with direct insertion of DPM lead to inadequate leaflet coaptation and apposition. This is the first report of mitral valve replacement for mitral regurgitation due to post-inflammatory valvular disease with DPM.
