My wife shown with 0.7 cm hole in heart, can it be treated with medicines or she has to go through surgery only?

The answer to this question will depend on the overall condition of your wife and her medical history. Generally speaking, a hole in the heart can be treated with either medicine or surgery depending upon the size, location and other factors like age.

In most cases, smaller holes (less than 1 cm) can be managed effectively with medicines alone especially in young patients without any major symptoms or complications associated with it. These medications work by helping prevent blood clots from forming within the hole and thus preventing any further damage to other organs such as lungs or rest of the cardiovascular system.

However, if the hole is larger (>1 cm) then surgical repair might be required along with medication for controlling symptoms associated with it such as breathlessness or chest pain etc. It is best to consult your doctor who can evaluate your wife's condition and discuss proper treatment approach accordingly keeping her overall health in mind.
