BackgroundWith the increased application of structural heart intervention techniques, there is concern over increasing radiation dose, especially during lengthy procedures.MethodsWe compared data from 91 consecutive single-vessel percutaneous coronary interventions, 69 patent foramen ovale closures, 25 atrial septal defect closures, 49 percutaneous transluminal mitral valvuloplasties, 57 balloon aortic valvuloplasties, 53 trans-catheter aortic valve implantations (TAVI), 21 left atrial appendage occlusions and 7 MitraClip® procedures.ResultsThe following fluoroscopy times and dose-area product (median, interquartile range) were recorded: patent foramen ovale closure (7.8, 5.3-10.9 minutes; 16.9, 7.5-30.6 Gycm2), atrial septal defect closure (10.1, 7.3-13 minutes; 15.5, 11.6-30.5 Gycm2), percutaneous transluminal mitral valvuloplasty (14.3, 11.4-24.2 minutes; 37.4, 19.8-87.0 Gycm2), balloon aortic valvuloplasty (8.4, 5.2-13.2 minutes; 19.8, 10.2-30.0 Gycm2), Edwards Sapien™ TAVI (24.0, 19.3-34.4 minutes; 86.4, 64.0-111.4 Gycm2), Medtronic CoreValve® TAVI (19.4, 15.0-26.0 minutes; 101.9, 52.6-143.2 Gycm2), left atrial appendage occlusion (18.5, 15.7-29.1 minutes; 84.1, 36.4-140.0 Gycm2), Mitraclip® procedures (37.2, 14.2-59.9 minutes; 89.1, 26.2-118.7 Gycm2), coronary angiography and single vessel percutaneous coronary intervention (6.6, 5.1-11.0 minutes; 62.5, 37.0-95.8 Gycm2).ConclusionFor structural heart interventions, dose-area product was not significantly greater than for coronary angiography with single-vessel percutaneous coronary artery intervention. This should be reassuring to patients and staff attending prolonged structural heart interventions.
