Abstract

The pressure transmission characteristics of the recently introduced Grüntzig super-low-profile catheter were evaluated for comparison with those of other coronary angioplasty catheters in clinical use. After thorough elimination of air bubbles from the pressure transmitting system the frequency response was linear (± 5%) up to 5 Hz and permitted recording of only minimally distorted arterial pressure tracings. With introduction of the 0.012’’ guide wire arterial pressure tracings remained adequate as long as the narrow catheter segment beginning just proximally to the balloon was not entered. Passage of the wire through the narrow distal segment resulted in severe overdamping even below 0.5 Hz.
