Dosimetric data and radiation risk analysis for new procedures in interventional cardiology

Abstract

The purpose of this study was to evaluate radiation doses to the patients and operators during interventional cardiology procedures, with a particular focus on the transcatheter aortic valve implantation (TAVI). Patient doses for 5549 diagnostic and therapeutic procedures and 76 TAVI were examined, as well as occupational doses to Cardiology Department operators. The average patient dose for TAVI was double that of PTCA and six times higher than a simple CA; statistically significant differences were shown in the average patient dose for both transfemoral and transapical access; the measurements show a corresponding increase in the average occupational dose for the cardiologist. Interventional cardiology could increase the collective dose and occupationally exposed worker doses; this increase could be significant if the use of certain procedures is extended to younger people; particular attention in the choice of procedure, optimisation and staff education and organisation is therefore suggested.

Effect of a Real-Time Radiation Monitoring Device on Operator Radiation Exposure During Cardiac Catheterization

“…Similarly, second operator radiation exposure was significantly lower in the Bleeper Sv group (5 [2-10] versus 7 [4][5][6][7][8][9][10][11][12][13][14] μSv; P<0.001; 29% relative reduction; Figure 3). Second operator radiation exposure was lower in the Bleeper Sv group both for diagnostic angiography (4 [2][3][4][5][6][7][8] …”

“…First operator radiation exposure was lower in the Bleeper Sv group both for diagnostic angiography (7 [4][5][6][7][8][9][10][11] versus 10 [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] μSv; P<0.001) and for PCI (11 [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] versus 14 [6][7][8][9][10][11][12][13][14][15][16][17]…”

Controlling Radiation Exposure in Interventional Cardiology

“…Patient dose is approximately double PCI and average operator dose is also increased. 21 Operator experience is also related to exposure with more experience operators having lower dose area product.…”

“…18,49 Os níveis de referência, portanto, estão bem estabelecidos para os procedimentos comuns e são exigidos pelas recomendações internacionais. 9,11,28,48 As doses nos procedimentos de Cardiologia Intervencionista podem chegar a variar em um fator 10 (Tabela 1) em procedimentos complexos, como a intervenção em uma oclusão coronária crônica, 50 a substituição de uma válvula aórtica transtorácica, 51 ou o reparo de um aneurisma endovascular torácico-abdominal, 52 os quais podem exceder a dose efetiva de 100 mSv.…”
