Patent Foramen Ovale Surgery Recovery Advice

My boyfriend had a stroke in February and was diagnosed with PFO (Patent Foramen Ovale). He is scheduled to have surgery soon, and I'm looking for advice on how to best support him during his recovery. For those of you who have undergone this procedure or have helped someone through it, what are some things that really helped you or your loved one? For example, a bed rest pillow. Thank you in advance!
