Outcome Measures

Primary Outcomes (1)

  • Diagnostic value of each biopsy procedure. It will be identified, how often biopsy contributed to the final diagnosis.

    24 months

Secondary Outcomes (1)

    24 Months

Other Outcomes (1)

  • Bleeding None, Mild degree (suction <= 3min), Moderate (extraction> 3min), Severe (intervention: tamponade, surgery)

    24 months
