Stress Echocardiography Versus Coronary Angiography for Left Main Stenosis Detection

Stopped: No Funding

Canada0Started 2010-07

Plain-language summary

Left main stenosis use to be treated by bypass but with the improvement of angioplasty techniques, an increasing number of patients are submit to left main coronary angioplasty. Consequences of left main intra stent stenosis can be disastrous yet, for the moment, no precise recommendation concerning the follow up of these patients exist. The investigators ought to determine if stress echocardiography can predict left main intra stent stenosis as well (non inferiorly)as control angiography that use to be done.

Exclusion Criteria: * Bypass on the left anterior descending coronary artery or left circumflex (" protected left main ") * Treating physician judge that angiography need to be done straightaway * Follow up elsewhere than the CHUS * Patient refusal * Pregnant women * Stress echo contraindication(Severe high blood pressure or malignant arrhythmia)or condition that limits interpretation (Left bundle branch block or pacemaker rhythm)

What they're measuring

Correlation between stress echocardiography results for the detection of left main prosthesis stenosis with coronary angiogram results.

Timeframe: 9 to 12 months after left main angioplasty
