59 yr old male diagnosed with aneurysm of Aortic Root(4.1) and ascending Aorta (4.2). No history ot marfans or hypertension. MRI from 12/06 indicates RV and LV normal in size with normal systolic function. Mitral, aortic and tricuspid valves and cnetral pulmonary valves normal. Echo from 10/06--consistent except Left atrium mildly dilated Right Atrium normal. LV mild concentric hypertrophy and mitral valve leaflets mildly thickened.
Results form 12/07 MRI---LV & RV mildly dilated normal systolic function, RA&LA moderately dilated, valves---no change, no change in anuerysm, EF 50%. Recent tests---BP 105/65, HR 55, Cholest: 121, HDL 40 , LDL 62, Trig 92. I feel great, no shortness of breath, speed walk up and down hills 4 miles daily. Take Atacand 24 mg, Vytorin 10/20, Atenolol 25 mg.
Question: My general MD says that the atriums are probably the size of my natural heart. this is not consistent with previous studies----can you explain the increase in atrium size---possible mis reading of MRI? Am i at risk? what can i do to reduce the enlargement? I worry about these things! Should i see my cardiologist? Previous CATS, EKG, and Stress (all w/i a 18 mos) no evidence of dialtin of atrium. I would appreciate your thoughts on this as i can not find a reason for the enlargement based on my searches.
