Catheter coronary sinus, position

With the guide catheter safely positioned in the coronary sinus and the target coronary sinus tributary identified, the coronary sinus lead can be placed. If a stylet-driven approach is used, success depends on operator experience, skill, coronary sinus anatomy, lead stylet selection and stylet management. Stylet... 

Fig. 5.5 An Alternative to Multiple Diagnostic Catheters in Fig. 5.4. This catheter with a deflectable tip permits multiple curvatures of the internal catheter within a long vascular sheath to facilitate cannulation of the coronary sinus. Once the long sheath is positioned into the coronary sinus, this catheter must then be removed before the left ventricular lead can be implanted.

Fig. 18J7 Still-frame from a cineangiogram foUowing coronary venous injection. A catheter is positioned in the coronary sinus. The faint blush that can be appreciated distal to the catheter tip represents a small amount of contrast material that has extravasated into the myocardial tissue.
