NCT04291898

Brief Summary

This is a proposal, for the first time in Canada, to examine the comparative effectiveness of three commercially available devices (ASO, FSO, and GAO/GSO) for transcatheter closure of atrial septal defects (ASD) in adults using a pilot randomized controlled trial.

Outcome Measures

Primary Outcomes (1)

  • Composite outcome of 'Clinical atrial fibrillation (AF)' or 'Major adverse cerebro-cardiovascular events (MACCE)

    At 24 weeks where clinical (AF) includes AF-related, ECG-documented, ED visit/hospitalization/physician visit, cardioversion, ablation or pacemaker implantation or new antiarrhythmic or AF anticoagulant prescription'; MACCE includes 'new onset heart failure (HF), HF-related ED admission, myocardial infarction, stroke, re-intervention, or death.

    24 weeks

Secondary Outcomes (11)

  • Subclinical AF (SCAF) burden (days):

    14 days

  • Subclinical AF (SCAF) burden (number of episodes):

    14 days

  • Subclinical AF (SCAF) burden (total time):

    14 days

  • Subclinical AF (SCAF) burden (percent time):

    14 days

  • Procedural effectiveness outcomes (acute technical success rate at discharge)

    Discharge, 24 weeks

  • +6 more secondary outcomes

Eligibility Criteria

Age18 Years - 110 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • ≥18 years old referred for percutaneous (secundum) ASD closure with right atrial and ventricular enlargement; and
  • clinically significant left-to-tight shunt (Qp:Qs≥1.5:1), or
  • evidence of paradoxical embolism (with a TEE defect \>10mm),
  • written informed consent

You may not qualify if:

  • TEE/CCT/CMR defect diameter \>30mm,
  • rim sizes of \< 5 mm to the coronary sinus, inferior vena cava rim, an atrioventricular valve, or the right upper pulmonary vein,
  • multiple defects,
  • complex congenital heart disease requiring surgical repair within 3 years of device placement,
  • Eisenmenger-syndrome,
  • recent myocardial infarction PCI/CABG \< 6 weeks,
  • demonstrated intra cardiac thrombi on echocardiography (especially LA or LAA thrombi), or atrial tumor
  • known occluded bilateral femoral veins/IVC,
  • pulmonary artery systolic pressure more than half the systemic systolic arterial pressure
  • recent pelvic venous thrombosis
  • serious comorbidity with life expectancy \<3 years (e.g., non-skin cancers not in remission, advanced renal failure serum creatinine \>160 umol/L)
  • patients whose size or condition would cause the patient to be a poor candidate choice for cardiac catheterization (e.g., too small for echocardiographic imaging probe, catheter size, vascular size, active infection, body weight \< 8 kg)
  • serious infection in \< 6 weeks producing bacteremia (e.g. sepsis), active endocarditis, or any other infection that cannot be treated successfully prior to device implantation (patient must have negative blood cultures off antibiotics for 1 week prior to procedure),
  • active GI bleed \< 6 weeks,
  • bleeding disorder, untreated ulcer, or any other contraindications to aspirin therapy, unless another antiplatelet agent can be administered for 6 months
  • +4 more criteria
