Abstract:
Objective To summarize application experience of attain(R) select Ⅱ catheter delivery system for left ventricular lead implantation in cardiac resynchronization therapy (CRT).Methods CRT/CRT-D was applied for 86 patients with congestive heart failure and left bundle-branch block.Left ventricular lead implantation was applied without use of attain(R) select Ⅱ catheter delivery system in 42patients without coronary vein anatomy variation (group A).Coronary sinus and cardiac vein angiography detected coronary vein anatomy variations in 44 patients and attain(R) select Ⅱ catheter delivery system was not used in 21 patients (group B) and used in 23 patients (group C).Total procedure time,LV lead implantation time,X-ray exposure time and complications were compared among groups.The optimal LV lead location were observed at the end of procedure.Results Patients were followed up to 245 days (160-368 days).Total procedure time[(119 ± 18) min vs.(142 ± 17) min；(119 ± 18) min vs.(143 ± 17)min],LV lead implantation time [(32 ± 7) min vs.(49 ± 8) min ； (32 ± 7) min vs.(51 ± 7) min] and X-ray exposure time [(27 ± 6) min vs.(46 ± 84) min ； (27 ± 6) min vs.(45 ± 7) min] were significant reduced in group C compared to group A and B.Procedure-related complications were similar among the 3groups.The rate of optimal LV lead location was significantly higher in group C than in group B(96％ vs.71％).Conclusions It is feasible and safe to implant LV lead through coronary sinus with attain(R) select Ⅱcatheter delivery system.Applying Attain(R) select Ⅱ catheter delivery system can improve the rate of optimal LV lead location with coronary venous anatomy variation.
