Thank you for your query,
With the information you provided, it is very difficult to comment on the treatment options for his enlarged heart
If the enlarged heart is due to heart failure
resulting from the underlying heart problem like congenital heart problem or due to acquired heart problem like rheumatic heart disease- the treatment is available directing towards decreased load on heart by digoxin
, lasix and followed by the definitive surgical repair of the primary problem.
If the enlarged heart is due to Dilated cardiomyopathy
the difinitive treatmet is heart transplantation
which involves the availability of donor and expenditure.
But the treating doctor is the best person to say the available options of treatment , so I advise you to discuss with him.
Hope I have answered your query.
