Hi welcome to Health care magic forum. You had mitral valve prolapse
and mitral regrugitation, It results in rt heart failure
, don't worry it is called like that. It should be examined periodically to estimate the condition of the heart.
Because with the advance of age the urge for oxygen
and nutrients will increase and hence the necessity for more blood flow, But the heart becomes old in proportion to the age, and left heart failure starts and the symptoms become more prominant and require increase in strength of medicines.
So periodical investigations and changing the strength of medicines is required for good maintenance of the body.
Besides i advise you some diet recommendations as use as little as possible of salt. Take more of green leafy vegetables , pulses, sprouts, and all nourishing food which help to improve the health of the heart muscles, and increase the quality and quantity of good blood to heart and all the tissues. Wishing for a quick and continuing recovery and thanks for calling.
