Variations and angulation of the coronary sinus tributaries: Implications for left ventricular pacing

Background Variations of the coronary sinus tributaries might result in difficulties in left ventricle electrode insertion during cardiac resynchronizing therapy. Morphometric features of tributaries, especially angulation of the coronary sinus tributaries, are crucial for coronary sinus procedures. Methods This study was carried out on 200 formaldehyde‐fixed human hearts (22.0% females, mean age of 48.7 ± 15.6 years). Results The inferolateral...
