[Coronary transluminal angioplasty and determination of the intracoronary gradient with a new monorail system].

STUDY OBJECTIVE

To evaluate the results obtained in coronary angioplasty using the new very low profile monorail catheter.

DESIGN

A retrospective study to define the causes and frequency of successful and unsuccessful coronary angioplasty on proximal and distal lesions located in the three coronary vessels.

SETTING

Patients referred to the Hemodynamic Unit for coronary angioplasty.

PATIENTS

Coronary angioplasty was performed in 106 patients with cardiac ischemic disease (stable angina, unstable angina and myocardial infarction after thrombolytic therapy).

INTERVENTIONS

To perform coronary angioplasty using a monorail system, including dilatation of vessels (angioplasty) and to measure the intracoronary gradient.

RESULTS

A high success rate was achieved (92%) independent of vessel dilated or of the position of the stenosis. There was a lower success rate in complex lesions.

CONCLUSION

In this study, this newly modified system for coronary angioplasty with balloon catheter and monorail pressure catheter gave a very high performance.
