Hi,
Let's start from the surgery. Your doctor may have explained to you that in
hypertrophic cardiomyopathy the heart muscle gets very thickened. Such thickened muscle may produce life threatening arrhythmias, that's why defibrillator was implanted, which is the most efficient way to prolong the life of patients with hypertrophic cardiomyopathy. Also, in some cases, the thickened muscle obstructs a part of the heart from where blood flows from the heart to the
aorta. Two types of surgeries, who mentioned are done in this case. They are meant to reduce the thickness of the muscle in the heart septum, thus, give a chance to blood flow to the aorta.
Heart failure in patients with hypertrophic cardiomyopathy have two causes 1. the obstruction I have mentioned above 2. when heart thickened heart muscle starts work weak, and heart can't pump enough blood to the body.
You can talk to your doctor to find out which one is the case of your husband.
In the first case, the surgery may help. In the second case, only medications are indicated.
The life expectancy of heart failure patients depends on many factors, one of them is how weak is heart muscle.
But usually if you can achieve good results with medications, his 5 year life expectancy may be quite high, especially if he have a defibrillator.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Lilit Baghdasaryan, Cardiologist
