PG - 1209-12 AB - BACKGROUND: Despite technical advances in tools used to facilitate implantation of cardiac resynchronization therapy (CRT) devices, there are many hurdles related mainly to the variation in the anatomy of the coronary veins. One such difficulty is the presence of a very sharply-angulated or tortuous of the lateral or posterolateral cardiac vein. METHODS: Totally 44 patients, 28 males and 16 females, with congestive heart failure and intraventricular conduction delay were studied retrospectively. There were 23 patients who had left ventricular (LV) lead implantation using standard techniques and equipment. For the other 21 patients with LV lead implantation we used the Attain Select II catheter delivery system. The patients were seen every 3 - 6 months for 12 months and the efficacy of the primary procedure, LV lead implantation time, procedure and fluoroscopy time and the complications associated with the two techniques were evaluated. RESULTS: There were no significant differences in the age, gender, New York Heart Association (NYHA) functional class, ischemic etiology, QRS duration, left ventricular ejection fraction, left ventricular end-diastolic diameter, left ventricular end-systolic diameter and LV dyssynchrony between the two groups. The LV lead implantation time, procedure time and fluoroscopy time were significantly shorter in the group using the Attain Select II catheter delivery system; LV lead implantation time from (51 +/- 7) minutes to (40 +/- 7) minutes (P < 0.001), procedure time from (143 +/- 17) minutes to (124 +/- 18) minutes (P = 0.001), and fluoroscopy time from (45 +/- 7) minutes to (35 +/- 6) minutes (P < 0.001). A successful procedure of LV lead implantation was significantly improved from 17/23 (74%) patients using the standard techniques and equipment, to 20/21 (95.3%) patients using the Attain Select II catheter delivery system (P = 0.06) CONCLUSION: It is feasible and safe to implant LV leads through the coronary sinus using the Attain Select II catheter delivery system.
