A 46 year old woman presented with sudden onset severe,

received intravenous tPA within two hours of symptom onset. Despite
thrombolysis, diamorphine, and intravenous
blockade, the
pain persisted. The ECG showed increased ST elevation.
She was transferred to the regional cardiac centre where examination
revealed persistent severe chest pain, tachycardia, and hypotension.
Coronary angiography showed an occlusive dissection flap in the
proximal left anterior descending coronary artery (fig 1A); circumflex
and right coronaries were normal. Balloon angioplasty resulted
in improved flow (fig 1B) and two overlapping intracoronary stents were
placed in the proximal and mid vessel (3.5 × 38 mm and

procedure had been completed (fig 1C), it became
