Abstract:
Objective CRT has gained acceptance as a useful form of device therapy for patients with refractory congestive heart failure. Despite recent technical advances, some problem still remained unsolved. The study highlighted some of these issues and try to provide possible solutions. Methods Since February 1999, about 50 patients underwent CRT. The CS lead was implanted with PTCA wire for dislodgment of lead in 3 patients. Injury of CS was present in 5 patients. Elevation in left ventricular pacing threshold was found in 2 patients who received early CRT. Results The patients who implanted the CS lead with PTCA wire acquired satisfactory capture threshold without any complication. Pace makers were implanted successfully in all 5 patients with CS injury The CS leads were extracted successfully from the 2 patients with elevated ventricular pacing threstold. Conclusion Implantation of the CS lead is a main step in the operation of CRT and prompt management to its related problems can enhance the operation success rate.
