Background |
Electrophysiology (EP) procedures have been reported to carry a significantly greater radiation risk than that of coronary angiography (CA). This is largely due to numerous reports linking severe deterministic radiation effects to long procedure and fluoroscopy times (FTs). This study documents low radiation doses achieved by strategies involving operator training and education as well as equipment and technique optimisation to reduce radiation risks.
Methods |
Records relating to 732 diagnostic EP and 1744 therapeutic EP procedures performed between January 2002 and December 2007 were analysed. Data from 1458 diagnostic only CA procedures performed in 2006 was used for comparison. For each procedure type, FT, number of digital frames acquired and estimated effective dose (E) were compared.
Results |
Although the FT for CA procedures is significantly less than for therapeutic EP procedures (FT for diagnostic EP being similar), EP procedures generally are associated with lower E, the exception being procedures for atrial fibrillation (AF).
Conclusion |
Through the application of a comprehensive exposure minimisation strategy, the radiation risk to patients undergoing diagnostic and, therapeutic EP procedures (except AF ablation procedures) is significantly less than that faced by patients undergoing CA. E, however, is heavily dependent on procedure type and as such care must be taken in undertaking generalised comparisons for audit and benchmarking purposes.
