Coronary angiography shows simultaneous stent thrombosis on LAD and OM1 (a) and restoration of good flow after thrombus aspiration, GPIIbIIIa inhibitor infusion and dilation with a semi-compliant balloon (b; yellow arrowheads highlight stent edges). Coronary angiography after 4 days of heparin infusion showed reasonable good results on both LAD and OM1 (c and d). IVUS showed well-stent strut apposition (red arrowheads; e, f, h and i) in both vessels with residual thrombotic material (pink area; f and i), causing a significant reduced minimal lumen area on OM1 (i).

Immediate coronary angiogram demonstrated simultaneous recurrent stent thrombosis of both LAD and OM1 stents (Fig. 1a). However, residual haziness was noted within both stents (Fig. 1b). After 4 days of intravenous heparin infusion, a repeat angiogram (Fig. 1c and d) with fractional flow reserve (FFR) and intravascular ultrasound (IVUS; Fig. 1e-g) was performed. Results were satisfactory in the LAD with an FFR of 0.84 (thus excluding significant residual ischaemic burden) and well-apposed stents were visualized in both LAD and OM1 using IVUS (Fig. 1 e, f, h and i). Fig. 1i). Further dilation to the stent in OM1 was then performed with a 3.5 x 15 mm non-compliant balloon with reasonable final results.
