Case ReportsMitral valve incompetence following blunt chest trauma after mitral valve repair. Recognition by three-dimensional echocardiography.
We present a unique case of mitral incompetence following blunt chest trauma in a 46-year-old woman who had undergone successful mitral valve repair 2 years before the accident. Three-dimensional echocardiography revealed the precise pathology, with partial avulsion of the annuloplasty ring and rupture of chordae tendineae.

Myocardial uptake and release of substrates in type II diabetics undergoing coronary surgery.
Knowledge about myocardial metabolism in diabetic patients is limited, and even more so in association with myocardial ischaemia and cardiac surgery. This study investigates myocardial substrate utilization in type II diabetic patients after elective coronary artery bypass graft surgery (CABG). ⋯ Free fatty acids were the main source of energy for the heart whereas uptake of carbohydrates was restricted. The high extraction rates of beta-hydroxybutyric acid and glutamate suggest an adaptive role for these substrates during this unfavourable metabolic state for the post-ischaemic diabetic heart.
