Coronary Sinus Dosing in Swine, Anatomical Considerations in Comparison to Human Anatomy

2022-09-23T14:55:59-05:00

Introduction: Routine cardiac catheterization for angioplasty and stenting has created a large population of patients with cardiac damage and subsequent long-term heart failure. Cardiac therapies are often administered directly to the heart by methods such as coronary sinus retrograde infusion. Understanding the differences in human and swine coronary sinus anatomy is crucial in preclinical safety studies, particularly for biodistribution evaluation. Contrast/ Dye studies aid in determining coronary sinus anatomy and catheter placement in the heart. Methods: Under general anesthesia, 9f or greater sheath was placed via jugular vein cutdown on three Landrace/ Duroc and two Yucatan swine. Using fluoroscopic guidance, a [...]
