@annak1691 I think you are on the right track. You need more details. If this is an aortic aneurysm, 3 cm is really small and I suspect it will be watched with yearly echocardiograms to assure it is not growing larger at a fast rate of speed. If you so far have just seen your primary, you may wish to get established with a cardio. You can discuss this with your primary when you call her for more details. Try not to worry -- if the issue were critical, your MD would have sent you to the ER, not home for the weekend.
