However, this approach effects in increased proportion of non-actionable ICAs (not followed by invasive treatment). Clinical efficacy and the safety of the strategy employing coronary computed tomography angiography (CCTA) as the first-choice imaging test in this population has been recently evaluated in the CAT-CAD randomised trial. Based on prospectively collected data we aimed to evaluate its economic outcomes. Methods: One hundred and twenty consecutive stable patients with indications to invasive CAD diagnosis were randomised 1 : 1 to undergo ICA versus CCTA as the firstline anatomic test. Outcomes were evaluated during the entire diagnostic and therapeutic course. Simultaneously, we counted the number of medical resources, such as: CCTAs, ICAs, percutaneous coronary interventions (PCIs), coronary artery bypass grafts (CABGs), functional tests, stents, clinical visits, hospital days. We estimated the cumulative cost for each strategy by multiplying medical resources by its standarised costs. Clinical Trials: NCT 02591992. Results: Economic analysis showed that the total cost of CAD diagnosis was significantly higher in the direct ICA group as compared to the CCTA group ($305,962 vs. $234,550), with the median per-patient cost of $2838 (2,838–2,838) vs. $409 (409–3,247), respectively (p = 0.0001). Similarly, the entire diagnostic and therapeutic course was significantly more expensive in the direct ICA group ($603,746 vs. $354,690), with the median per-patient cost of $2,838 (2,838–16,102) vs. $409 (409–9,930), respectively (p < 0.0001) (Figure 1). Conclusions: Application of CCTA as the first-line anatomic test in patients with suspected significant CAD decreased the total costs of diagnosis. This benefit can be achieved by reducing the number of invasive tests and hospitalisations.

Some implications for clinical cardiology of recent advances in interventional cardiology.
RECENT YEARS have seen the development of many new techniques and therapies that are useful or potentially useful in the management of patients with cardiovascular diseases. A number of these procedures performed by cardiologists have given rise to the term "interventional cardiology," referring to the more active, interventional role of the physician performing the procedure as compared with t...

Introduction The increasing practice of interventional fluoroscopy in diagnosis and treatment of cardiovascular disease has risen attention to improve radiation protection of patients and cardiologists in these relatively high dose techniques. Therefore, nowadays there is an emphasis on the measurement of radiation dose received by patients and cardiologists arising from the relevant procedures...

Background: The number of interventional cardiology procedures performed has increased rapidly over the past years. While these procedures help physicians avoid using highly complicated invasive methods, it usually leads to high levels of exposure to ionizing radiation of both patients and cardiologist. The dose received by the cardiologist during interventional cardiology procedures is determi...
