  • 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.
Same as current
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.

EP-Catheter Guided CS-Lead Implantation
Conventional Versus EP-Catheter Guided Implantation of Coronary Sinus Lead in Patients Undergoing Cardiac Resynchronization Therapy

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.

Probability Sample

Patients with symptomatic heart failure and reduced left ventricular ejection fraction. Asynchronic contraction of left and right ventricle was reflected by QRS duration > 120 ms in left precordial leads.

  • Heart Failure
  • Reduced Left Ventricular Ejection Fraction
  • Left Bundle Branch Block
Not Provided
  • 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.
