|Indication as Listed in the AC for Echocardiography||Percent of All Studies for Which the Indication Was Covered in the AC for Echocardiography (n = 1,385)|
|Number 1: Symptoms potentially caused by suspected cardiac etiology, including but not limited to dyspnea, shortness of breath, lightheadedness, syncope, TIA, cerebrovascular events||28% (n = 384)|
|Number 2: Previous testing that is concerning for heart disease (i.e., chest X-ray, baseline scout images for stress echocardiogram, ECG, elevation of serum BNP)||9% (n = 122)|
|Number 43: Re-evaluation of a patient with known heart failure (systolic or diastolic) to guide therapy in a patient with a change in clinical status||6% (n = 81)|
|Number 10: Evaluation of known or suspected pulmonary hypertension including evaluation of right ventricular function and estimated pulmonary artery pressure||5% (n = 70)|
|Number 17: Initial evaluation of murmur in patients for whom there is a reasonable suspicion of valvular or structural heart disease||5% (n = 62)|
|Number 31: Initial evaluation of suspected infective endocarditis (native and/or prosthetic valve) with positive blood cultures or a new murmur||4% (n = 54)|
|Number 11: Evaluation of hypotension or hemodynamic instability of uncertain or suspected cardiac etiology||3% (n = 45)|
|Number 36: Evaluation of pericardial conditions including but not limited to pericardial mass, effusion, constrictive pericarditis, effusive-constrictive conditions, patients post-cardiac surgery, or suspected pericardial tamponade||3% (n = 39)|
|Number 41: Initial evaluation of known or suspected heart failure (systolic or diastolic) in whom there is no change in clinical status||3% (n = 38)|
|Number 42: Routine (yearly) re-evaluation of patients with heart failure (systolic or diastolic) in whom there is no change in clinical status||3% (n = 37)|
Results are reported as the percentage of all studies for which for which indication is covered in the AC for Echocardiography.
AC = Appropriateness Criteria; BNP = brain natriuretic peptide; ECG = electrocardiogram; TIA = transient ischemic attack.
