Dear cardiologists: my husband (47 y.o.) has had 2 ablations already due to tachycardia (one of them atrial fibrillation) with no success and now he is on heart and anticoagulant medicines, but can't handle side effects... what are his options now?

Has he had side effects (bleeding) from the anticoagulants despite careful management. If so, and if he is still atrial fibrillation, one option would be left atrial appendage closure with an implanted device. This decision needs a full understanding of the procedure by your husband, an electrophysiologist with the required experience etc. My suggestion is that you arrange to have this discussion
