Key result
Novel reverse-curve catheter reliably traverses the right ventricle into the pulmonary artery without complications.
Why the study?
A new pulmonary-artery-seeking catheter design was developed to facilitate passage from the right ventricle to the pulmonary artery with minimal manipulation.
Does a new pulmonary-artery-seeking catheter with a reversed secondary curve allow safe and effective pulmonary arteriography in humans and dogs?
Does a new pulmonary-artery-seeking catheter with a reversed secondary curve allow safe and effective pulmonary arteriography in humans and dogs?
A newly designed pulmonary-artery-seeking catheter with a reversed secondary curve facilitates easy and safe transfemoral selective bilateral pulmonary arteriography.
May simplify pulmonary artery access in select cases; leaves open routine adoption pending larger validation studies.
A new, improved pulmonary-artery-seeking catheter is described. This catheter has a reversed secondary curve; when introduced from the right femoral vein, it passes readily from the right ventricle to the pulmonary artery with a minimum of manipulation. This catheter design has been successfully applied without complications in humans and dogs.
