I am a 31 year old male. I exercise 6 times weekly (High Intensity) running and sprinting and heavy weight lifting. Sometimes two session (morning lift/afternoon run). I have been running (30-60 min) for about 12 years. I have mild hypertension which is well controlled with Diovan 160mg daily. Recently I was having breathlessness, racing heart (particularly during exercise), palps, and anxiety. Blood work has revealed painless Thyroiditis (Very Low TSH, High T3, Low Radioiodine Uptake). In the meantime a CARDIAC ULTRASOUND was orderd and the results are below. Are these values representitive of Heart Disease (Particularly the biatrial enlargement), or could the enlargement be due to my history of athleticism. Thanks very much in advance.
LA DIAM (1.9-4.0): 3.8 CM LVIDD (3.7-5.6): 5.1 CM
AO ROOT DIAM(2.0-3.7): 3.4 CM LVIDS (2.0-4.0): 3.1 CM
POSTER WALL (0.6-1.1): 0.9 CM SH FRACT (28-46): 39 %
SEPTUM (0.6-1.1): 0.9 CM RVIDD (0.7-2.6): 2.5 CM

LVOT DIAM (1.5-2.4): - CM LA VOL ( <50 ): 63 mL
ASC AO DIAM (2.0-3.7): 3.2 CM RA VOL ( <50 ): 58 mL
INTERPRETATION:
1. The left ventricle demonstrates normal and systolic diastolic
dimensions, left ventricular wall thickness is normal. Left
ventricular systolic function is normal with a calculated apical
biplane ejection fraction of 57% and normal regional wall motion.
2. There is a false tendon noted in the mid left ventricle.
3. The right ventricle is normal in size with normal right ventricular
systolic function. There is a moderator band present in the apex of
the right ventricle.
4. The left atrium is mildly enlarged though there is mild biatrial
enlargement and an intact interatrial septum.
5. The aortic valve is trileaflet with no evidence of AI or AS.
6. The mitral valve is structurally normal. There is trace mitral
regurgitation. No mitral stenosis. Mitral inflows demonstrate
normal diastolic parameters and tissue Doppler E/E' ratio of 4 is
consistent with normal estimated left atrial filling pressures.
7. The tricuspid valve is structurally normal. There is trace tricuspid
regurgitation. The peak regurgitant velocity is 2.8 m/sec
correlating to a peak estimated PA systolic pressure of 30-35 mmHg.
8. The pulmonic valve is structurally normal. There is trace to mild
pulmonic insufficiency. No pulmonic stenosis.
9. The IVC is normal in size and demonstrates normal inspiratory
collapse.
10. There are no masses or effusions.
11. The ascending aorta and aortic root are both normal in dimensions.
