BACKGROUND: Atresia of the coronary sinus orifice with a persistent left superior vena cava is an intrinsically benign cardiac anomaly with important surgical implications. METHODS: THe medical records of 5 patients with atresia of the coronary sinus orifice with a persistent left superior vena cava were reviewed retrospectively, and a computer search of the world literature describing this cardiac malformation was undertaken. RESULTS: The 5 patients ranged in age from 9 months to 5 years. In 2, the diagnosis was made preoperatively by angiocardiography, and in 3, the abnormality was found incidentally at the time of cardiotomy for repair of associated congenital heart disease. Four of the 5 patients underwent repair of associated cardiac lesions. During operation, care was taken to avoid disruption of left superior vena cava flow to prevent coronary venous obstruction. All patients survived and are doing well at follow-up. CONCLUSIONS: Atresia of the coronary sinus orifice with persistent left superior vena cava is, in itself, a benign anomaly without physiologic consequence. However, the recognition of this lesion during repair of associated cardiac lesions is of vital importance to the cardiac surgeon. Interruption of this sole route of coronary venous drainage can potentially lead to myocardial ischemia and necrosis.
PURPOSE: The aim of this work was to study the safety and efficacy of iobitridol 350 in pediatric angiocardiography compared to iopamidol 370. MATERIAL AND METHODS: 40 children participated in each test group. Each examination was rated as diagnostic or nondiagnostic and the image quality was noted. Nature,onset,intensity as well as outcome of each adverse reaction was reported. RESULTS: There was no significant difference in either image quality or clinical safety between the 2 groups. CONCLUSION: Iobitridol is a safe and effective contrast agent for pediatric angiocardiography.
OBJECTIVE: To describe pattern of utilization of noninvasive cardiac diagnostic test in Ontario. DESIGN: Retrospective analysis using Ontario Health Insurance Plan (OHIP) administrative data. SETTING: Ambulatory care settings in Ontario. MAIN OUTCOME MEASURES: First, the volume of services and expenditures on electrocardiograms (ECG), ambulatory ECG, radionuclide angiocardiograms (RNA), echocardiograms, exercise stress tests (EST), and myocardial perfusion scintigrams from 1989/90 to 1992/93; second, the number and specialty of physicians performing these tests. MAIN RESULTS: Ontario spent $119 million on noninvasive diagnostic cardiology test in 1992/93, representing 2.67% of total OHIP expenditures. Expenditures on these procedures grew by 49.3 % over the four-year period, exceeding the overall OHIP growth rate, and was most rapid for nuclear cardiology and echocardiography. Changing demographics accounted fpr only a minor portion of expenditure growth. Second, age-adjusted utilization rates for EST, myocardial perfusion scintigraphy and RNA were higher for men, but sex differences tended to diminish over time. Third, utilization rates differed markedly by geographic region, and variations were greatest for nuclear medicine studies. Geographic variations tended to be attenuated over time. There was also wide variation in the frequency with which physicians performed Doppler studies with two-dimensional echocardiography. CONCLUSIONS: The use of noninvasive cardiac diagnostic test has grown rapidly in recent years. This growth may have been influenced by practice guidelines, by greater diffusion of, and access to, newer technology and by more testing in women. Wide regional variations suggest that clearer practice guidelines are needed concerning the appropriate use of noninvasive cardiac diagnostic investigations.
