Hi I hope the gymn is not done anymore, in my opinion the valves can be wrecked by the weights because the valve is thin and not like the thick heavy outside part of the muscle.
In my opinion this might especially happen if wine was taken and judgement a bit foggy so that the usual breathing technique is not followed. If it is too heavy it might happen in my opinion regardless of technique.
Wine sludges blood and is not suggested, it may cause a clot in my opinion. It is far better to get a juicer and make real fresh grape juice for antioxidants if any beverage is needed. With a heart problem even liquids should be carefully used, not too little and not too much, the amount depending on the weight of the person involved.
For exercise in the future I suggest it might be better to do a nice brisk walk outside in the sunshine and fresh air.
