Cardiac Vein Anatomy and Transcoronary Sinus Catheter Interventions in Myocardial Ischemia

First published: 06 May 2022

Summary

For the interventional cardiologist, transcoronary sinus interventions (trans-CSI) became more important for the treatment of microvascular obstruction, no reflow zones, and to enhance and support the healing process of myocardial infarcts. To understand the clinical potential of trans-CSI one has to study the special features of the anatomy and pathophysiology of the cardiac venous system. The proximity between cardiac veins accessible for transcoronary sinus catheter interventions and coronary arteries, as well as the distance between mitral annulus and the great cardiac vein, shows the limitations to some of the methods used to correct structural and functional heart disease. The breakthrough in trans-CSI occurred at the advent of resynchronization therapy. Transcoronary sinus catheter interventions developed from historic arterial retroperfusion techniques. Dedicated knowledge focusing on transcoronary sinus catheter interventions are currently supplying the necessary technology and equipment.
