Welcome. The condition you are telling is a serious thing. If there are clots inside your heart they are moving than you should be alarmed. These clots can go to brain as you said they have already gone, Lung-causing pulmonary embolism which is also a serious condition. They can go to extremities like hands legs and can cause gangrene. We generally give blood thinner to such patients which helps in keeping the blood thin thus decrease embolism. These blood thinner should continue life long. You will also need a trans esophageal echoTEE to know exactly the size of hole whether it could be closed. So please make an appointment with your cardiologist soon for further management. If you want any further help, Ill be happy to assist you. Thanks
