Atrial pacing in the detection and evaluation of coronary artery disease.

Atrial pacing has been recently re-evaluated as a stress test for the detection of coronary artery disease. This sort of stress, especially if used in conjunction with cardiac imaging techniques can be considered a reliable alternative to physical exercise. In patients with recent myocardial infarction it can be usefully and safely utilized to obtain prognostic information. In fact, patients with recent myocardial infarction and a positive electrocardiogram (decreases ST greater than or equal to 1 mm) during atrial pacing more frequently than others present subsequent major cardiac events. Limitations of traditional pacing test (invasivity, poor sensitivity of electrocardiography) can be overcome with a new test we have recently proposed: two-dimensional echocardiography during atrial pacing. We have used this new stress test to detect patients with significant coronary artery disease, to identify patients with myocardial infarction and multivessel disease and to evaluate the effect of coronary artery bypass surgery.

Hydatid cyst of the interventricular septum causing obstruction of the right ventricular outflow tract: cross-sectional echocardiographic, angiographic and pathological findings.

Cardiac echinococcal cysts rarely involve the interventricular septum; when they do, they cause symptoms mainly related to the compression of the atrio-ventricular conduction pathways. Mild obstruction of the right ventricular outflow tract has also been described in some cases. In the case reported here, an unusual large hydatid cyst located in the interventricular septum produced a marked, symptomatic obstruction of the right ventricular outflow tract (more than 100 mmHg gradient). Surgical resection of the cyst was complicated by a 'stone heart' syndrome, probably because of a severely affected right ventricle. Cross-sectional echocardiography gave the exact site and aetiology of the mass. On the basis of these non-invasive findings, early surgery should be performed on asymptomatic patients to reduce the risk of life-threatening evolutions.
