The prevalence of coronary sinus and left circumflex artery overlap in relation to the mitral valve.
Characterize where the circumflex artery crosses between the coronary sinus and mitral valve in order to minimize the occurrence of coronary compression during percutaneous indirect mitral valve interventions. ⋯ The prevalence of circumflex overlap between the coronary sinus and mitral valve was common across the sample size. The large variability in anatomy confirms the value of imaging individual patient cardiac anatomy prior to performing indirect percutaneous mitral valve annuloplasty to avoid impairment to the circumflex artery. This novel database can be utilized in the development of additional cardiac therapies that require access to the coronary sinus, such as therapeutic ablations.
