• 1 other identifier: 2019-A02398-49
• Study Type: observational
• Target: 83
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study is therefore to study the actual doses of X-rays delivered to the patient's skin during recanalization of a coronary artery in a context of Chronic Total Occlusion

Conditions

X-rays; Effects; Chronic Total Occlusion

Outcome Measures

Primary Outcomes (1)

• Dose measured to the patient's skin at the entrance to the X-ray beam

  Dose expressed in Gy (Peak skin dose).

  1 month

Study Arms (1)

Patient requiring intervention (complex coronary dilation or coronary recanalization)

Patient requiring intervention with a predicted risk of exceeding the radiological threshold (Air Kerma\> 3Gy): complex coronary dilation, coronary recanalization

Radiation: Gafchromic film

Interventions

Gafchromic film RADIATION

Before the X-ray radiation, a Gafchromic film will be placed on the patient's back at the start of the operation

Patient requiring intervention (complex coronary dilation or coronary recanalization)
