Aortocoronary collateral

Reconstruction of an extracardiac aortocoronary collateral and simulation of selective angiography with multidetector-row computed tomography.

Iatrogenic aortocoronary • veIn fistula

A patient underwent aortocoronary saphenous bypass grafting to the left anterior descending coronary artery (LADA) and its first diagonal branch for the relief of severe angina pectoris. There was difficulty in exposure of the LADA, which was covered by a thick layer of epicardial adipose tissue. Postoperatively the patient continued to experience severe retrosternal pain which prompted early r...

Aortocoronary dissection complicating percutaneous angioplasty.

A 56-year-old man was admitted to our hospital for elective coronary angioplasty of a chronic total occlusion (CTO) of the right coronary artery (RCA). After insertion of a right femoral sheath, the RCA was engaged with a 6 French Amplatz AL-2 (Cordis, Miami, Fl, USA) guiding catheter. Recanalization was begun using a 0.014-inch Miracle 3 guidewire (Asahi Intecc, Japan). At this stage, an ostia...

Ruptured giant aortocoronary vein graft aneurysm.

A 62-year old man, with aortocoronary bypass 25 years before, re-presented with increasing chest pain. A computed tomography (CT) documented a ruptured giant true aneurysm of the vein graft to the left anterior descending (LAD), which was distally blocked (Fig. 1). Peripheral cannulation and redo sternotomy under deep hypothermic circulatory arrest were used to resect the aneurysm (Fig. 2), wit...

Aortocoronary vein graft spasm, a clinical entity?

T he concept that saphenous veins which have been transplanted into the arterial circuit are passive, unreactive conduits may be an oversimplification. The unique report by Victor et al in this issue (see page 413) proves that such vein grafts can go into severe spasm. Their report describes a patient who suffered recurrent angina pectoris after undergoing a triple coronary artery bypass operat...
