Table 3. Prioritization of CCT indications during the COVID-19 pandemic.

	Low-priority indications	Medium-priority indications	High-priority indications (consider performing in the next hours or in up to 2 to 4 weeks)
CAD	Calcium score in asymptomatic patients		Acute chest pain with high enough suspicion of CAD
	Stable chest pain without high suspicion of CAD		Stable chest pain with high risk of cardiovascular events, or when high-risk anatomy is suspected
Structural cardiac disease	Patients with stable structural cardiac disease (TAVR, TMVR, LAA occlusion, together with the Heart Team)		Patients requiring urgent structural intervention (TAVI, TMVR, LAA occlusion)
Atrial fibrillation	Assessment of pulmonary veins for planning atrial fibrillation ablation	Evaluation of the left atrial appendage in chronic atrial arrhythmia before restoring sinus rhythm	Evaluation of the left atrial appendage in acute atrial arrhythmia before restoring sinus rhythm
Heart failure	Investigation of CAD as cause of heart failure in patients with stable cardiomyopathy		Hospitalized patient with acute cardiomyopathy and low or intermediate probability of CAD, where CCT can change management
			Evaluation of left ventricular assist device malfunction
Valvular	Assessment of aortic stenosis severity	Subacute or chronic prosthetic valve dysfunction	Acute and symptomatic prosthetic valve dysfunction, endocarditis, perivalvular extension of endocarditis or possible abscess
Masses/ congenital	Suspected benign cardiac masses or those unlikely to require biopsy or surgical planning		New suspected malignant cardiac masses or those requiring biopsy or surgical planning
	Elective assessment of congenital anomaly		Ruling out left ventricle thrombus after inconclusive echocardiography, when alternative methods (magnetic resonance) are not available

CAD: coronary artery disease; TAVR: transcatheter aortic valve replacement; TMVR: transcatheter mitral valve replacement; LAA: left atrial appendage; CCT: cardiovascular computed tomography.
