Sones at the Cleveland Clinic
Mason Sones at the Cleveland Clinic is credited with performing the first selective coronary angiography in the late 1950s when an inadvertent selective injection revealed coronary anatomy and led to deliberate development of selective coronary catheterization techniques which provided direct visualization of coronary arteries and transformed diagnosis and management of ischemic heart disease
Impact on Cardiology and Interventional Techniques
Selective coronary angiography enabled precise localization of coronary lesions and informed the development of percutaneous coronary interventions and surgical revascularization strategies and it became a cornerstone diagnostic procedure in cardiology and a platform for therapeutic innovation
Safety Evolution and Imaging Integration
Coronary angiography spurred improvements in catheter design contrast agents hemodynamic monitoring and imaging guidance and integration with other modalities such as intravascular ultrasound and with physiologic assessment tools enhanced lesion characterization and procedural decision making
