My mom had a stroke today

My mom has had a heart condition all her life and a month ago she got checked out by a doctor for the first time in 20 years and found out she had 3 months to live. After doing tests we found out she did not have the 3 valves she was supposed to but had 1 that was basically “pinched” as was explained and also had an aneurism in her heart . Fast forward to Friday she had open heart surgery and has been in recovery . She did well in the surgery and has been recovering slowly , but this afternoon she had what was explained as a “small stroke”. She’s still as aware as before and is talking normal she just has slight droopiness and weakness in her left side. I’ve been trying to do research because the doctors haven’t been very helpful tbh but I can’t find if those are the only things we need to worry about or if tomorrow she might have more symptoms ? She immediately had a CT scan and they didn’t find anything abnormal , just seems like it happened because of her previous heart condition. I’m sorry if this isn’t the right subreddit for this question , tbh I’m just a scared 23 year old trying to figure out the extent of what’s going on with her mom.
