A Case of an Obstructive Intramural Haematoma during Percutaneous Coronary Intervention Successfully Treated with Intima Microfenestrations Utilising a Cutting Balloon Inflation Technique

Figure 2

(a) Significant luminal stenosis at the level of two small diagonal branches (arrows) after deployment of the stents and postdilatation of the overlapping segment with the 3.5 mm stent balloon at 16 atmospheres. Stenosis did not resolve after intracoronary administration of two consecutive 300 mcg bolus doses of nitrates. (b) Further overlapping stenting resulted in propagation of the haematoma and significant distal luminal stenosis after the level of the two small diagonal branches (arrows).
