This study enrolls adults who are having a cardiac or cerebrovascular procedure that uses a device called a transcranial doppler. This study is collecting data to look at the changes in blood flow during these procedures. The data collected will help researchers develop techniques and strategies to minimize risk for stroke for future patients. Your participation in the study will not involve anything in addition to the care you are already getting- the study collects information that is already being collected as part of your care. We expect that you will be in this research study for few days until your discharge from the hospital up to your 3 month follow up visit. This study takes place only at Buffalo General Medical Center and Gates Vascular Institute. Read More
