Brief Summary:
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.

Condition or disease

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

Primary Outcome Measures :
  1. Total Fluoroscopy Time [ Time Frame: During implantation ]
    During CRT device implantation fluoroscopy is used and the total fluoroscopy time is counted.

  2. Contrast medium account [ Time Frame: During surgical procedure ]
    contrast medium is used and counted during crt device implantation.

Secondary Outcome Measures :
  1. Successful implantation [ Time Frame: During surgical procedure ]
    Successful crt implantation was defined as effective positioning of RV and CS lead +/- right atrial lead.

Other Outcome Measures:
  1. Procedure related complications [ Time Frame: 24 hours after start of surgery ]
    All complications during time frame of 24 hours after start of surgery were proved whether they were procedure related.
