Chronic Total Occlusion (CTO) Intervention (2)
Coronary chronic total occlusion (CTO) represents one of the most complex situations in the field of interventional cardiology. It is the complete blockage of blood flow in the arteries supplying the heart muscles. CTO can be formed by multiple layers of calcified plaque or blood clots and tissue.
Based on the characteristics such as the end cap shape, hardness, length, etc, various combinations of advanced atherectomy and angioplasty procedures will need to be performed to remove a CTO blockage. Presence of other nearby blood vessels, and patient factors such as comorbidity also increase the complexity of the procedure.
