EP-Catheter Guided CS-Lead Implantation
In patients undergoing CRT device implantation a lead positioning in the coronary sinus is required. Even this part of the surgical procedure is challenging. In this study we compared retrospectively to methods of CS-lead implantation: conventional vs. EP-catheter guided.

- Total Fluoroscopy Time [ Time Frame: During implantation ] [ Designated as safety issue: Yes ]During CRT device implantation fluoroscopy is used and the total fluoroscopy time is counted.
- Contrast medium account [ Time Frame: During surgical procedure ] [ Designated as safety issue: Yes ]contrast medium is used and counted during crt device implantation.
- Successful implantation [ Time Frame: During surgical procedure ] [ Designated as safety issue: No ]Successful crt implantation was defined as effective positioning of RV and CS lead +/- right atrial lead.
- Procedure related complications [ Time Frame: 24 hours after start of surgery ] [ Designated as safety issue: Yes ]All complications during time frame of 24 hours after start of surgery were proved whether they were procedure related.

In this group CS lead was implanted in a conventional manner.
In this group coronary sinus was canulated using a steerable electrophysiology catheter.
