I have CHF and will be having open heart surgery to replace a valve, how long is recovery and will I be in a lot of pain after surgery?

Mostly 3 months. It depends on which valve, how many valves, how the surgery will be done, and your current physical condition. If you are young, doing fine and have normal kidneys, liver, and lungs, and have the surgery for one of your valves, you will recovery quickly like 5 days hospitalization and 1.5-3 months for full recovery.
It depends. The recovery time is dependent on your general state of health prior to surgery (true of any surgery), the healthier you are, the quicker the recovery. Most likely, your hospital stay (if you're otherwise healthy) will be about 5-6 days and then it will take several weeks to get back to "normal". There will be some pain early on, but will get better quickly hopefully.
6 weeks, no. You should be better than you were before surgery within about six weeks. You should not have a lot of pain after the first two weeks.
10-12 wks to recover. It takes about 10-12 wks to recover if no major post operative complications. Expect a few wks faster recovery if done minimally invasive. Hospital stay after surgery is about 5-7days.
Two months. You will hopefully only spend 3-5 days in the hospital. It will take a couple weeks to feel better from the surgery, one month for driving, two months before the sternum is healed and then resume full activity. Pain is very subjective, but also depends on the approach: sternotomy, thoracotomy, minimally invasive etc. Over all the pain should be taken care adequately by your doctors.
One to 3 months. It depends on several things including the age and fitness of the patient as well as the technique used to replace the valve. In general less invasive techniques have a recovery of 4 to 6 weeks and conventional surgery 6 to 12 weeks.

I had open heart surgery to replace my auortic valve. Now they are saying I have cystic medial necrosis. Does this mean I have marfans?

Possibly. One of the features of Marfan's (a disorder of abnormal collagen tissue formation) is cystic medial necrosis, leading to abnormal tissue within the layers of the aorta which can lead to anneurysm formation of the aorta (a risk for regurgitation, rupture, and dissection). When such an aortic root measures more than 50 mm in diameter, these risks increase and require aortic root repair +/- avr if ai.
Not necessarily. Cmn is an inherited disorder that increases the chance if developing aneurysms and dissections of the aorta and other large vessels. It is a disease of what we call connective tissues. It is often found associated with marfan's but can also be seen in patients with ehlers-danlos syndrome and annuloaortic ectasia.

My sister had an open heart surgery onths ago now she is in hospital with congestive heart failure what's the chance to survive?

Ask her doctor. With her permission. We do not have enough information to make that assessment. Her cardiologist is in the best position to make that assessment. Wish you and her the best.
Multiple variables. Survival in this setting depends on the amount of cardiac damage (lv function), upon the severity of CHF symptoms, the associated systemic tissue perfusion, and other comorbidities (like renal function, diabetes, bp, and cardiac arrhythmias that might be present. Overall, the pre-bypass heart function coupled with such comorbidities will dictate long term prognosis. Respiratory status.
Depends. Sorry your sister is sick. Prognosis with heart failure depends on a lot of things like age, other illnesses, heart function, the reason for the heart failure, and the extent to which this can be addressed.

Is open heart surgery the only way to address discrete subaortic stenoisis (membrane behind the aortic valve? Are there alternatives?

Subaortic stenosis. Can be congenital or acquired at different ages. You must have a cardiologist and have regular ECHOS. The SAS, usually is muscular cardiomyopathy, which narrows the tunnel for the blood to go through the valve. As the resistance increases, is indication for surgery. Cure of fixed subaortic stenosis (SAS) remains a surgical challenge.
