Background: In order to evaluate the cost-effectiveness of coronary angiography performed in a low volume Center, we examined our 1-year activity., Methods: The organizational model of the multipurpose cardiac catheterization laboratory is described. In this type of facility both coronary angiographic and electrophysiological studies are performed. To evaluate the laboratory performance we examined the utilization level, the appropriateness of the studies, the complication rates and the number of studies that had to be repeated because of inadequate data or image quality. The costs were calculated for the in-house laboratory setting (the actual scenario) and for the 25 km distant laboratory setting (the historical scenario)., Results: The laboratory caseload of coronary angiography was 342 studies, 46% of the overall laboratory activity; 175 patients (51%) underwent non-pharmacological therapy, 129 patients (38%) were treated with medical therapy; the percentage of patients with normal coronary arteries was 11%. Two patients (0.58%) had vascular complications, 1 patient (0.29%) developed an acute myocardial infarction 2 hours after coronary angiography without any evidence of angiographic modifications at the repeated study. In no patient the study had to be repeated because of inadequate data or image quality. The mean cost of a coronary angiography was Lit. 512,000 (265 Euro) for the actual scenario; it would have been Lit. 694,000 (359 Euro) for the historical scenario, with Lit. 182,000 (94 Euro) saved., Conclusions: These findings are consistent with the accepted criteria of good laboratory performance and cost-effectiveness. Thus coronary angiography can be performed effectively and efficiently in a low volume Center.

Pulmonary embolism is a life-threatening condition that is accompanied by significant morbidity and mortality. In massive pulmonary embolism, where restoration of pulmonary arterial flow is urgently required, the only options available are surgical thromboembolectomy and/or thrombolytic therapy. Unfortunately, a large part of thromboembolic diseases is also considered as an absolute or relative contraindication to thrombolysis. The purpose of this paper was to emphasize the possibility of new thrombolytic agents of disregarding, according to circumstances, the contraindications to thrombolytic treatment.

Acute pancreatitis and/or gallbladder disease precipitating angina pectoris, or producing arrhythmias or ST-T wave changes on electrocardiography in the absence of coronary artery disease, have frequently been mentioned. Many attempts have been made to explain the etiology of these findings. To the authors' knowledge, this report is the most dramatic expression of pathogenetic mechanisms which are still considered hypothetical.
