Fig 32.9: Angioplasty and Coronary Brachytherapy

A: Chronic total occlusion of the middle Right B: PTCA using a balloon of 10mm length and 3.0 Coronary Artery (mid RCA) mm diameter

D: Endovascular brachytherapy using an Ir-192 seed ribbon consisting of 14 seeds (55mm Active Source Length (ASL))to treat a Planning Target Length (PTL) of 34 mm. Reference Isodose Length (RIL) is 46 mm. Prescribed dose was 14 Gy at 2mm from the source axis according to the GRANITE trial protocol and the Reference Depth Dose (RDDo) was 11 Gy.

C: PTCA using a balloon of 20mm length and 3.0 mm diameter resulting in a post intervention result of 2.8 mm Reference Lumen Diameter (RLDi) and 2.4 mm Minimal Lumen Diameter (MLD).The entire Interventional Length (IL) was 24mm.

E. 6-months follow-up showing a good angiographic result and no symptoms of angina.
