Cardiovascular Imaging and Interventional Procedures Arq Bras Cardiol. 2020; 115(1):111-126 • Symptomatic prosthetic heart valve dysfunction, endocarditis, perivalvular extension of endocarditis, and possible valve abscess; • New cardiac tumor suspected to be malignant; • Need to rule out intracavitary thrombus. Outpatient procedures considered elective can be rescheduled timely, within 4-8 weeks. 37 However, the decision about which procedures defer should be carefully made. Telemedicine can help in decision making and criteria assessment. Figure 2 summarizes the recommendations to support the decision about performing or deferring the exams. Stable patients should be considered for CCTA, which usually requires the administration of heart rate control drugs and coronary vasodilators. Ideally, low radiation and contrast dose protocols should be chosen. 38 It is worth observing and describing in the exam report the pulmonary findings that might aid the patient’s clinical management. 4.4.
