Incidence of new pulmonary perfusion defects after routine cardiac catheterization

Deep venous thrombosis and pulmonary embolism following cardiac catheterization

“…The cooperative study on cardiac catheterization [6] noted only 11 instances of pulmonary embolism and infarction in a total of 12,367 right heart and transeptal left heart catheterizations performed between 1963 and 1965. Primm et al [7] found a 12% incidence of new perfusion lung defects after right and left heart catheterizations in 57 adult patients. None of the patients were symptomatic.…”

The clinical significance of pulmonary embolism: uncertainties and implications for treatment – a debate

“…A final group of high risk patients was studied by Primm et al [19] who performed VQ scans on 57 patients following cardiac catheterization and found PE in seven (12 %). All of these patients were asymptomatic.…”

Incidence of new focal pulmonary emboli after routine cardiac catheterization comparing the brachial to the femoral approach

“…However, in those two reports there is no mention of how the diagnosis of pulmonary embolus was confirmed. Primm et a1 [9] noted an incidence of 16% of pulmonary emboli after the femoral approach and 8% after the brachial approach. This could be explained by the fact that in the latter study the patients were prospectively randomized into two groups: one in which right heart catheterization was performed using an antecubital venous cutdown, and another in which the percutaneous femoral vein approach was used.…”
