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

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.
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.
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.

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?

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. Read more...
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. Read more...
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. Read more...
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. Read more...
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. Read more...
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.

A friend of mine was in the hospital, and she said she had to get an ablation on her heart. What does that mean? Is that like open heart surgery?

Ablation. In this procedure a device is introduced into the femoral artery in the groin and treaded up to the heart. The device has an RF tip (radio frequency) which can be used to burn the superficial tissue in the heart in the attempt to disrupt aberrant pathways. These pathways are causing an irregular heart rate. Once these pathways are carefully mapped the cardiologist ablates the abnormal pathways. Read more...
