Endurance Exercise Low Risk After Bicuspid Aortic Valve Aneu
Patients who have undergone surgery to repair an aortic aneurysm related to having a bicuspid aortic valve have a low risk of future aneurysm events even if participating in endurance exercise. The study included a case series of 21 individuals who have been participating in many endurance events for a mean of 8 years following this surgery without any aneurysm events having occurred.

Results showed that the athletes resumed endurance exercise or competition at a mean of 5.7 months after thoracic aortic aneurysm repair. Athletes cumulatively completed nearly 300 endurance events including marathons, triathlons, and Ironman competitions. Most participants (76%) exercised 4 to 6 days per week, and five individuals exercised daily. Athletes exercised for a mean of 1.4 hours per day. All but one individual reported that they did not perform any intense weight training. At last clinical follow-up, a mean of 8 years after thoracic aortic aneurysm resection, all 21 individuals were actively exercising and competing, and no adverse outcomes.
