In a large multicentre cohort of adults with Marfan syndrome, cardiac surgery was common and redo sternotomy occurred frequently among operated patients, with hypertension, emergent initial operation, and postoperative complications independently associated with increased odds of redo sternotomy.
Key Findings
Results
The majority of adults with Marfan syndrome in this cohort underwent at least one cardiac operation.
Total cohort included 783 adults with Marfan syndrome evaluated across three Mayo Clinic sites.
454 patients (58.0%) underwent at least one cardiac operation.
Data were collected via retrospective chart review at three Mayo Clinic sites.
Study design was a retrospective multicentre cohort study.
Results
Redo sternotomy was required in nearly one-quarter of the total cohort and nearly half of operated patients.
185 patients required redo sternotomy, representing 23.6% of the total cohort and 41.0% of operated patients.
This highlights the high long-term surgical burden in adults with Marfan syndrome.
Redo sternotomy events were identified by chart review.
Results
The most common cardiac procedures performed were aortic root interventions, followed by aortic valve, mitral valve, and tricuspid valve interventions.
Aortic root intervention was performed in 53.4% of operated patients.
Aortic valve intervention was performed in 39.6% of operated patients.
Mitral valve intervention was performed in 16.1% of operated patients.
Tricuspid valve intervention was performed in 2.6% of operated patients.
Results
Valvular abnormalities were highly prevalent in this Marfan syndrome cohort.
Mitral regurgitation was present in 51.5% of patients.
Mitral valve prolapse was present in 41.1% of patients.
Tricuspid regurgitation was present in 44.6% of patients.
Aortic regurgitation was present in 28.5% of patients.
Valvular findings were identified through echocardiographic data.
Results
Major postoperative complications occurred in 15.3% of patients following cardiac surgery.
15.3% of patients who underwent cardiac surgery experienced major postoperative complications.
Postoperative complications were identified through chart review.
Postoperative complications were subsequently found to be an independent predictor of redo sternotomy.
Results
Hypertension was independently associated with increased odds of redo sternotomy on multivariate analysis.
Odds ratio for hypertension and redo sternotomy: OR 2.39, 95% CI 1.54 to 3.72.
Association was identified using multivariate logistic regression.
This finding suggests hypertension as a modifiable risk factor for repeat cardiac surgery in Marfan syndrome.
Results
Emergent initial cardiac operation was independently associated with substantially increased odds of redo sternotomy.
Odds ratio for emergent initial operation and redo sternotomy: OR 3.38, 95% CI 1.97 to 5.80.
This was the strongest independent predictor of redo sternotomy among the factors examined.
Association was identified using multivariate logistic regression.
Results
Postoperative complications following the initial cardiac operation were independently associated with increased odds of redo sternotomy.
Odds ratio for postoperative complications and redo sternotomy: OR 2.59, 95% CI 1.58 to 4.27.
Association was identified using multivariate logistic regression.
This suggests that complications after initial surgery may set the stage for further surgical interventions.
Results
Aortic repair extending beyond the aortic root was associated with significantly lower odds of redo sternotomy.
Odds ratio for repair extending beyond the aortic root and redo sternotomy: OR 0.39, 95% CI 0.29 to 0.53.
This was a protective association identified on multivariate logistic regression.
This finding may suggest that more extensive initial aortic repair reduces the need for future reoperations.
What This Means
This research suggests that adults with Marfan syndrome—a genetic condition that affects connective tissue and frequently leads to problems with the aorta and heart valves—face a very high likelihood of needing heart surgery during their lifetime. In a study of 783 adults seen at three Mayo Clinic locations, more than half (58%) underwent at least one cardiac operation, and among those who had surgery, 41% eventually required a second or subsequent open-heart surgery through the same chest incision (called a redo sternotomy). The most common procedures were on the aortic root and aortic valve, though many patients also needed mitral or tricuspid valve surgery. Valve abnormalities such as mitral regurgitation and tricuspid regurgitation were extremely common in this population.
The study identified several factors that increased the likelihood of needing repeat cardiac surgery. Having high blood pressure (hypertension), undergoing an emergency initial heart surgery, and experiencing major complications after the first surgery were all independently associated with higher odds of requiring a redo sternotomy. In contrast, patients who had a more extensive initial aortic repair—one that extended beyond just the aortic root—were significantly less likely to need repeat surgery. Major postoperative complications occurred in about 15% of surgical patients, underscoring the complexity of cardiac surgery in this population.
This research suggests that early, proactive management of Marfan syndrome—including blood pressure control and timely (rather than emergent) surgical intervention—may help reduce the need for repeat open-heart surgeries. The finding that more extensive initial aortic repair lowers the risk of redo surgery could have implications for surgical planning. These results provide an important contemporary picture of the long-term cardiac surgical burden faced by adults with Marfan syndrome cared for at specialized referral centers.
