Is my best friend going to survive heart surgery?? Please help me!!!? My best friend was diagnosed with a light aortic stenosis and an aneurysm in her aorta less than 2 weeks ago. She was suffering from angina pectoris since she was little. severe chest pain , retrosternal pain and bardikardia were part of her every day life. 2 days ago she just passed out and fell into coma and never woke up ever since. Doctors consider her condition as critical and want to operate surgically in the next couple of hours when her condition doesn t improve. I m so scared for her. She is only 21 and she s my best friend; she has her whole life ahead of her. Will heart surgery really improve her living quality ? Will she be healthy again ? Is she really going to wake up ? I don t know what to do anymore. Please help!! =(
