Atrial fibrillation
Multifocal Atrial Tachycardia (MAT)
Frequent Atrial Premature Contractions
More than 50 premature ventricular contractions per
Inability to lie flat
Body mass index >40
Calcium (Agatston) score of 1000 or more
Inability to hold breath for >8 seconds
Renal insufficiency (serum creatinine>1.5 mg/dL)
1.1.1 No prior Calcium Scoring for 5 years
1.1.2 No prior abnormal stress tests, coronary CTs, or catheterizations
1.2.1 No prior Calcium Scoring for 5 years
1.2.2 No prior abnormal stress tests, coronary CTs, or catheterizations
1.2.3. Results of coronary calcium scoring would influence the prescription of statin therapy6
2.1. Evaluation of pulmonary vein anatomy prior to invasive radiofrequency ablation for atrial fibrillation
2.2. Non-invasive coronary vein mapping prior to placement of biventricular pacemaker
2.3. Non-invasive coronary arterial mapping, including internal mammary artery prior to repeat cardiac surgical revascularization
2.4. Evaluation of native or prosthetic valve, cardiac mass, or pericardial mass when a prior CT, cardiac MRI, or echocardiogram was performed for this indication and was non-diagnostic
2.5. Evaluation of left and/or right ventricular function when a prior echocardiogram, MRI, or MUGA was performed for this indication and was non-diagnostic
2.6. Characterization of aortic valve morphology (i.e. trileaflet or bicuspid) when not able to determine by echocardiography7
2.7. Arrhythmogenic right ventricular dysplasia/cardiomyopathy is suspected8 [BOTH]
Based on any one of the following: echocardiographic evidence of regional RV akinesia, dyskinesia, or aneurysm; repolarization abnormalities on electrocardiogram (e.g. inverted T waves in right precordial leads in individuals>14 years of age in the absence of complete right bundle branch block); depolarization abnormalities on electrocardiogram (e.g. epsilon waves in right precordial leads); arrhythmia (e.g. non-sustained or sustained ventricular tachycardia of left bundle branch block morphology or >500 ventricular extrasystoles/24 hours on Holter monitoring); or family history
No cardiac MRI has been performed because there is a contraindication to MRI OR a cardiac MRI was performed but was non-diagnostic
3.1.1. Evaluation of thoracic arteriovenous anomaly (CTA or MRA preferred)
3.1.2.1. No cardiac CT or cardiac MRI has been performed and there is contraindication to MRI
3.1.2.2. A cardiac CT or cardiac MRI was performed one year ago or more
4.1.1 No stress or angiographic studies in prior 60 days
4.1.2 Evaluation of coronary arteries in patients with new onset heart failure to assess etiology
4.2.2 No ECG changes
4.2.3 Serial enzymes negative
