Brief Summary
During diagnostic and interventional coronary procedures scatter radiation exposure is recorded with live-dosimeters at pre-specified anatomic regions of operators and sterile assistants. Scatter radiation data is correlated with detailed Xray exposure data and technical details of the procedure. The purpose of the registry is:
- 1.to establish scatter radiation reference values based on a large number of representative cath-lab procedures
- 2.to identify technical and clinical factors predisposing for high scatter radiation exposure,
- 3.to evaluate advanced radiation protection devices in clinical routine.

Outcome Measures
Primary Outcomes (1)
Intra-procedural Xray scatter radiation exposure (µSv)
Xray scatter radiation dose recorded by 5 personal live dosimeters (3 allocated to the operator, 2 allocated to the sterile assistant).
Duration of procedure
Interventions
Scatter radiation exposure of the operator and sterile assistant is recorded with digital live dosimeters at 3 locations of the operator (frontal head at eye level, left lateral head, below the left shoulder) and at 2 locations of the sterile assistant (left neck and below the left shoulder)
Eligibility Criteria
Two study populations have to be considered separately: 1. PDL Recordings: Study population: Interventional cardiologists regularly assigned to our Cath-labs working at the cath-lab table during the majority of their assignment. 2. Coronary procedures during which data is recorded: Study population: Patients with clinical indication for diagnostic or interventional coronary procedures, representing the classic cardiologic patient population with suspected or known coronary artery disease, acute coronary syndrome or heart valve dysfunction.
You may qualify if:
- Patient scheduled for coronary angiography
- Diagnostic procedure and PCI
- Acute and elective procedures
- Standard percutaneous coronary interventions (PCI) interventions
- Chronic total occlusion (CTO) interventions
- Set of at least 4 personal digital live dosimeters (PDL) worn by operator and sterile assistant for the entire duration of the procedure
- Staff (operators and assistants) instructed on PDL positioning prior to procedure
You may not qualify if:
- Less than 4 PDL present during the procedure
- Incomplete data recording by at least 1 PDL
- PDL data cannot be unambiguously assigned to a specific procedure or a specific anatomical recording site
- Exchange of operator or assistant during procedure without transfer of all PDL
