Cardiac Findings in Sarcoidosis

Most Commonly Affected Sites:

 - LV free wall (esp. basal posterior wall)

 - Interventricular septum. (esp. basal)

LV Myocardial Involvement:

 - LV wall thickening

 - LV wall thinning

 - Focal hypokinesis or RWMA

 - LV Aneurysm

 - Global systolic dysfunction (+LVEF)

 - Reduced myocardial strain

 - Diastolic dysfunction

 - Papillary muscle involvement

Valvular Abnormalities:

 - Mitral regurgitation due to primary thickening of leaflets

 - Mitral or tricuspid regurgitation secondary to ventricular dysfunction or pulmonary hypertension

Pericardial involvement:

 - Effusion

ECG Abnormalities:

 - Advanced atrioventricular block

 - Ventricular arrythmias (V. tachycardia, multifocal)

 - Right bundle branch block

 - Axis deviation

 - Abnormal a-wave
