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

Figure 4

(a) Intramural haematoma (green arrow) can cause luminal obstruction, with significant flow disturbances resulting in significant ischaemia and ensuing myocardial infarction. (b) After single cutting balloon inflation at nominal pressure, the balloon blades generate several microfenestrations on the intima surface. The result is the creation of various blood exit points (blue arrows) that relieve the internal haematoma pressure towards the lumen of the vessel and restore normal blood flow.
