My cardiac thoracic surgeon recommended me to see a cardiologist for baseline cardiac workup. This included an EKG and scheduled echocardiogram to check out heart valves etc. You need to study all structures of the heart and check for any leaking of valves. Anyway, he has an associate who is also a cardiologist but she also does testing for a specific gene that families can carry and pass down which is responsible for causing aneurysms. It's not going to be helpful in our aneurysms but early awareness for our offspring. Early detection , awareness and being pro-active is crucial. Hopes this is helpful. Best regards.
