I have had skipped heart beats (PVCs) for as long as I can remember. My aneurysm was found in 2012 and I had either an echo or ct scan every year for 12 years. There was never more than 2 or 3 mm difference between them year to year. My aneurysm slowly grew from 4.5 cm to 5.2 cm over that time and I had surgery 3 months ago. My PVCs were much worse after the surgery but it has slowly been improving.
