Figure 4: Case Example of a Chronic Total Occlusion of Right Coronary Artery Involving a Previous Stent Recanalised by Antegrade Approach, Treated with a Single Drug-coated Balloon and Follow-up Angiographic Appearance at 4 Months.

A 74-year-old man with a history of two coronary artery bypass grafts (first, early 1990s; second, 2013) and percutaneous coronary intervention to right coronary artery (RCA) and left circumflex artery, presented with limiting angina. (A) Pre-treatment angiographic appearance. The chronic total occlusion of RCA involving previous stent was recanalised by antegrade approach, predilated and finally treated with a single drug-coated balloon (DCB). A type C dissection was noted and left with no stent cover as there was Thrombolysis In Myocardial Infarction (TIMI) III flow. (B) Shows the result immediately following DCB-only angioplasty. (C) At 4-month follow-up the dissection was well healed and the result was excellent.
