Abstract 3319: Early and Late Complications of Cardiac Resynchronisation Therapy: A Single Centre Experience Over 8 Years of 402 Patients
Aims Despite increasing number of implants worldwide, little is known about the acute and long term incidence of complications related to cardiac resynchronisation therapy (CRT). We report on a large single centre registry data, including patients with complex cardiac pathology.
Methods Retrospective data of all acute and chronic complications occurring over 490 consecutive CRT device procedures in 402 patients, from 2000 –2008, were analysed.
Results Mean age of patients at implant was 65±15 years, 31% were female. The majority were CRT-D (70%), with smaller proportions of CRT/Tri-ventricular-P (17.2%) and Tri-ventricular/dual RV CRT-D (12.6%). Duration of follow up was 1012±610days. 67% were new implants, 14% system upgrades, 9% lead replacements, 4% generator change/revision and 2% system explants.
Conclusions CRT patients experience complications in both the acute and chronic period following implant. The majority of complications relate to early and late device infections and lead displacements. Serious complications are rare and inability to implant the LV lead is acceptably low. Complication rates are significantly higher in patients with complex structural heart disease and non-ischaemic cardiomyopathy.
