Background: Interventional cardiologists are occupationally exposed to high doses of ionizing radiation. The MAVIG X-ray protective drape (MXPD) is a commercially available light weight, lead-free shield placed over the pelvic area of patients to minimize operator radiation dose. The aim of this study was to examine the efficacy of the MXPD during routine cardiac catheterization, including percutaneous coronary interventions. Methods: We performed a prospective, randomized controlled study comparing operator radiation dose during cardiac catheterization and percutaneous coronary intervention (n=632) with or without pelvic MXPD. We measured operator radiation dose at 4 sites: left eye, chest, left ring finger, and right ring finger. The primary outcomes were the difference in first operator radiation dose (µSv) and relative dose of the first operator (radiation dose normalized for dose area product) at the level of the chest in the 2 groups. Results: The use of the MXPD was associated with a 50% reduction in operator radiation dose (median dose 30.5 [interquartile range, 23.0–39.7] µSv in no drape group versus 15.3 [interquartile range, 11.1–20.0] µSv in the drape group; P <0.001) and a 57% reduction in relative operator dose ( P <0.001). The largest absolute reduction in dose was observed at the left finger (median left finger dose for the no drape group was 104.9 [75.7–137.4] µSv versus 41.9 [32.6–70.6] µSv in the drape group; P <0.001). Conclusions: The pelvic MXPD significantly reduces first operator radiation dose during routine cardiac catheterization and percutaneous coronary intervention.

Abstract The stochastic and non-stochastic (deterministic) effects of radiation dose in patients undergoing primary percutaneous coronary intervention (PPCI) have been investigated using data recorded by an angiographic monitoring system. A total of 132 patients with acute myocardial infarction referred to the angiography department of Vali-Asr hospital, Fasa, Iran, during the second half of 2016 were recruited. Quantities like dose–area product (DAP), total air kerma (Ka,r) and fluoroscopy time (FT) were calculated and converted into effective dose (ED) and peak skin dose (PSD). The values for Ka,r, DAP and FT equaled 80 399.20 ± 63 312 mGy cm2, 1392.80 ± 1155.373 mGy and 524.11 ± 423.057 s, respectively, which were within the ranges reported in previous studies. After considering standard dose thresholds for Ka,r and PSD, it was revealed that only a small portion of patients had reached these thresholds and exceeded them (<3%). Moreover, ED < 20 mSv for the majority of patients was fairly consistent with results from a recent research in eight Belgian hospitals. It was shown that angiographic records are reliable for assessing radiation dose in patients.

There is a gap in the literature regarding fetal radiation exposure from interventional cardiac procedures. With an increasingly large and complex cohort of pregnant cardiac patients, it is necessary to evaluate the safety of invasive cardiac procedures and interventions in this population. Here we present a case of a patient with multiple medical comorbidities and non-ST elevation myocardial infarction (NSTEMI) at 15 weeks’ gestation, managed with percutaneous coronary intervention (PCI). We were able to minimize the maternal and estimated fetal absorbed radiation dose to <1 milliGray (mGy), significantly less than the threshold dose for fetal adverse effects at this gestational age.
