Brief Summary:
The study will evaluate the long-term safety and efficacy of intravascular beta radiation therapy to treat coronary in-stent restenosis using the Beta-Cath(TM) 3.5F System; data will be collected retrospectively on patients treated with the Beta-Cath™ 3.5F System in routine clinical practice following FDA pre-market approval of the System. Outcomes will be reported up to 5 years following treatment.

Criteria

Inclusion Criteria:

  • Patients who underwent on-label treatment (as defined below) with the Beta-Cath™ 3.5F System (30, 40 or 60mm) for in-stent restenosis (ISR) after coronary stenting.

    1. On-label treatment for the 30 and 40mm Beta-Cath™ 3.5F System is defined as: treatment of ISR in native coronary arteries with discrete lesions (treatable with a 20mm balloon) in reference vessel diameters (RVD) ranging from 2.7mm to 4.0mm
    2. On-label treatment for the 60mm Beta-Cath™ 3.5F System is defined as: treatment of ISR in native coronary arteries with lesions <40mm in length in RVD ranging from 2.7mm to 4.0mm

  • Patients must have undergone brachytherapy treatment at least 6-8 months prior to enrollment in this retrospective study and the date of their treatment must be:

    1. On or after February 8, 2002 for the 30/40mm 3.5F System
    2. On or after June 25, 2003 for the 60mm 3.5F System

Exclusion Criteria:

  • Patients who do not give informed consent
  • Patients who do not meet the inclusion criteria
