Drug-eluting balloon angioplasty for bifurcated chronic total coronary occlusion

This is the case of a 67-year-old woman admitted due to a 6-month history of exertional angina. Stress echocardiography showed severe anterior wall ischemia. The patient was referred for coronary angiography that revealed the presence of a chronic total coronary occlusion of the proximal left anterior descending coronary artery (LAD) immediately before the bifurcation with the first diagonal branch (D1) from the septal collaterals of the right coronary artery (figure 1A, video 1 of the supplementary data). The patient signed the written informed consent, and a chronic total coronary occlusion recanalization was performed 6 months after the index angiography.
