Physical Examination

• Prominent A wave with elevation of JVP may be present.

Auscultation

Heart Sounds

• Prolapsing of atrial tumor into the mitral valve orifice results in delay in closure of mitral valve producing a loud S1.
• There is a delay in P2, intensity of which depends on the absence or presence of pulmonary hypertension.
• Atrial tumor striking against the endocardial wall may produce an early diastolic sound known as the tumor plop.
• In some cases S3 and S4 may also be present.

Murmur

• In case of obstruction of mitral valve by the atrial tumor, a diastolic atrial rumble is heard.
• If atrial tumor results in damaging of the mitral valves leading to mitral regurgitation then a systolic murmur is heard at the cardiac apex.
• In case of right atrial tumor, a diastolic rumble due to obstruction of the tricuspid valve and a holosystolic murmur due to tricuspid regurgitation may be present.

Syndromes associated with Cardiac Tumors to be cognizant of during the Physical Examination

• NAME syndrome: It refers to:

• nevi,
• atrial myxoma,
• myxoid neurofibroma, and
• ephelides (i.e., freckles [tanned macules found on the skin])

• LAMB syndrome: It refers to:

• lentigines,
• atrial myxoma, and
• blue nevi
