Can an enlarged heart be made normal again

My blood pressure, until last year, was always around 90/60; last year it shot up to 234/198 and I had a three hour nose bleed that was stopped with a coagulate med shot when I was rushed to the hospital. From that point on it fluctuated for a month in the 119/90 area ... until I found a good hypertension Doctor who, after dozens of tests, got it under control with norvasc; it still runs around 140/76, so I have just now had the 5 mg increased to 10mg. I have had atrial Fib, ventrical tachicardia and mitral valve prolaspe for 35 years but was not caught until 10 years later; in the past 15 years it has been under control with atenolol and no more episodes for the past 7 years, just a slight amount of arrythmia once in a while. I, also, have just a very slight irregularity in my atrial heart valve.  4 yrs ago I had tremendous water retension and swelling of my leg after a hip replacement and gained 10 lbs over night. They thought I had heart failure but yearly echos have confirmed that I do not; the echos in 2008 showed I had a slight amount of atrial enlargement, Now, the echo I had yesterday shows my right and left atrial chambers are severly enlarged. I have had some angina pain but I think it is mostly from stress, since I had angina pain yesterday after I was told my heart was now severly enlarged. My weight is very normal, I have no shortness of breath, my endurance is quite good; however, I had to give up my walking 5 miles aday after my hip replacement. I have cooked only mediterranian diet food for 20 years. Is it possible that my blood pressure, even though not really high is causing the enlarged heart?  Is it alot more dangerous to have an enlarged heart? Does the enlarged heart mean that I now will have more atrial fib, or other heart problems? Is it possible for me to get my heart size back to normal size and if so, how?  What other tests can I take that will give me a guide line on the best things I can do for myself to maintain good heart health inspite of a few heart problems.  My mother and father both died with heart problems.

Who told you your heart is enlarged and how did they determine it?  What is your left ventricular ejection fraction?  Have you been given a treatment regimen to address the situation by whoever found this out?

p.s., I missed your echo reports.  But I'm still wondering what your LVEF is.  The atrial enlargement is probably due to leaky valves, the enlargement probably lead to the a-fib.

I suffered from an leaky mitral valve for a number of years - maybe all my life - and it eventually caused my left atrium to enlarge to a critical degree. This was treated with open heart surgery to repair the mitral valve.  This was done in 2007 at the senior age of 67.  The surgeon forecast that the reduction in pressure in the left atrium due to a proper operation of the mitral valve would allow the heart to shrink back toward normal... not all the way (remember my age) but much better.  This has happened and I am now planning to try another electrocardioversion to treat my AFig.  

There are other causes of an enlarged heart, I believe high blood pressure can cause enlargement of all chambers.  

My point?  Yes, there are treatments for at least some causes of an enlarged heart that will help the heart return to a more normal size, at least not to continue to enlarge.  I'd guess a young person, say someone under 50 (that's young to me), would have a heart that is more able to shrink back to its normal size that would a heart of someone over 65.... just picking some numbers, I do not have any study numbers on age heart shrinkage.
