An unusual complication after aortocoronary bypass grafting (CABG) is described in which a false aneurysm of the saphenous vein graft to the right coronary artery (RCA) developed and caused profuse intermittent bleeding through the sternotomy wound. The aetiology of this condition is uncertain but it could occur whenever a suture line is present especially in the presence of infection. The diagnosis was made non-invasively by a contrast enhanced computed tomogram and was subsequently confirmed by selective coronary bypass angiography. The pseudoaneurysm was successfully obliterated by coil embolisation of the right coronary graft, which stopped the bleeding immediately and was followed by rapid wound healing.

1. Changes in left ventricular structure and function were assessed by echocardiography in 22 patients before and after 9 months blood pressure control. 2. Nine patients had normal baseline echocardiograms (group 1) and 13 had echocardiographic evidence of left ventricular hypertrophy (group 2). 3. Group 2 patients demonstrated significant reductions in posterior wall thickness (P < 0.01), septal wall thickness (P < 0.025) and left ventricular mass (P < 0.005). Only six of the 13 patients showed a reduction of greater than or equal to 3 mm in posterior wall thickness. The remainder showed no alteration or only a slight non-significant reduction. 4. The regression of voltage in some patients but not in others did not appear to be related to initial blood pressure, the extent of the fall in blood pressure or duration of follow-up. It was not possible to say whether any specific therapy was beneficial to regression since most of the patients were on multiple therapy.
