The Swedish Coronary Angiography and Angioplasty Registry (SCAAR) represents a large, valuable cohort for future studies on the clinical importance and optimal treatment of chronic total occlusions.
Highlights potential CTO treatment gap in Sweden; leaves open SCAAR's value for future outcome studies.
CTO is a common finding in Swedish patients undergoing coronary angiography but the number of CTO procedures in Sweden is low. Patients with CTO are a high-risk subgroup of patients with coronary artery disease. SCAAR has the largest register of CTO patients and therefore may be valuable for studies of clinical importance of CTO and optimal treatment for CTO patients.
