In many patients with chest pain of esophageal origin, findings are normal on routine esophageal manometry and dysmotility develops only upon provocation with ergonovine maleate. Unfortunately, ergonovine may induce myocardial ischemia in patients in whom coronary artery spasm did not occur during previous provocative testing in a cardiac laboratory - limiting its clinical usefulness. We have recorded esophageal pressure simultaneously with ergonovine infusion during angiography in ten patients without significant arterial stenoses. In two patients their usual chest pain developed associated with esophageal spasm and without changes in coronary vessels. Simultaneous performance of angiography and manometry enhanced the diagnostic yield of provocative testing by showing esophageal motility changes. This method may detect significant changes in the esophageal motility, is easy to carry out and does not interfere with angiography. It maximizes the information gained from a single provocative test and avoids the risk of ergonovine infusion outside of a cardiac laboratory.
