Korábbi kezelés

• Known existing circumferential pericardial effusion >2 mm prior to catheter insertion.
• Implanted intracardiac device within 30 days prior to the procedure
• Patients who have had a ventriculotomy or atriotomy within 28 days prior to the procedure
• Known sensitivity to contrast media (if needed during the procedure) that cannot be controlled with pre-medication
• Previous left atrial surgical procedure (including left atrial appendage (LAA) closure device)
• Previous tricuspid or mitral valve replacement or repair
• Patient is currently participating in another clinical trial or has participated in a clinical trial within 30 days prior to screening that may interfere with this clinical trial without pre-approval from this study Sponsor

Más betegség

• Known presence of cardiac thrombus.
• Presence of any condition that precludes appropriate vascular access
• Myocardial infarction (MI), acute coronary syndrome, percutaneous coronary intervention (PCI), or valve or coronary bypass grafting surgery within preceding 90 days
• Stroke or TIA (transient ischemic attack) within the last 90 days
• History of blood clotting or bleeding abnormalities including thrombocytosis, thrombocytopenia, bleeding diathesis, or suspected anti-coagulant state
• Rheumatic heart disease
• Active systemic infection
• Severe pulmonary disease (e.g., restrictive pulmonary disease, constrictive or chronic obstructive pulmonary disease) or any other disease or malfunction of the lungs or respiratory system that produces severe chronic symptoms
• Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements of the clinical investigation results.

Egyéb
