EUROPEAN HEART JOURNAL OPEN 2024; 4:oead138. [PMID: 38223303 PMCID: PMC10786438 DOI: 10.1093/ehjopen/oead138] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 12/12/2023] [Accepted: 12/18/2023] [Indexed: 01/16/2024]
Abstract
Aims Coarctation of the aorta is associated with long-term morbidity including decreased exercise capacity, despite successful repair. In the absence of discrete recoarctation, the haemodynamic mechanism remains unknown. This multicentre study evaluated the relationship between aorta shape, flow, and exercise capacity in patients after arch repair, specifically through the lens of aortic size mismatch and descending aortic (DAo) flow and their association with exercise. Methods and results Cardiac magnetic resonance, cardiopulmonary exercise test, and echocardiogram data within 1 year were analysed from 58 patients (age 28 ± 10 years, 48% male) across four centres with history of isolated arch repair. Aortic arch measurements were correlated with % predicted VO2max with subgroup analyses of those with residual arch obstruction, bicuspid aortic valve, and hypertension. Ascending aorta (AAo) to DAo diameter ratio (DAAo/DDAo) was negatively correlated with % predicted VO2max. %DAo flow positively correlated with VO2max. Sub-analyses demonstrated that the negative correlation of DAAo/DDAo with VO2max was maintained only in patients without arch obstruction and with a bicuspid aortic valve. Smaller aortic arch measurements were associated with both hypertension and exercise-induced hypertension. Conclusion Aorta size mismatch, due to AAo dilation or small DAo, and associated decreased %DAo flow, correlated significantly with decreased exercise capacity after aortic arch repair. These correlations were stronger in patients without arch obstruction and with a bicuspid aortic valve. Aorta size mismatch and %DAo flow capture multiple mechanisms of altered haemodynamics beyond blood pressure gradient or discrete obstruction and can inform the definition of a successful repair.

Frankel WC, Roselli EE. Strategies for Complex Reoperative Aortic Arch Reconstruction in Patients With Congenital Heart Disease. Semin Thorac Cardiovasc Surg Pediatr Card Surg Annu 2023; 26:81-88. [PMID: 36842802 DOI: 10.1053/j.pcsu.2022.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2022] [Revised: 12/16/2022] [Accepted: 12/20/2022] [Indexed: 12/28/2022]
Abstract
Aortic dilation is common in patients with congenital heart disease including those with a bicuspid aortic valve, connective tissue disease, coarctation of the aorta, and conotruncal defects. In addition, neo-aortic dilation has been described in patients after aortic reconstruction including the Norwood procedure, the arterial switch operation, and the Ross procedure. Although aortic catastrophe is rare in patients with congenital heart disease, common pathologic endpoints in these patients likely manifest with similar aortic tissue behavior. A lifelong care model with similar indications for surveillance and prophylactic repair to other more common aortopathies is therefore warranted. Still, reoperative aortic arch reconstruction in these patients is often a complex and high-risk endeavor, and in all cases, a tailored and adaptable plan ensuring adequate myocardial and cerebral protection with appropriate rescue measures is paramount. A surgical team taking on these challenging cases should possess an armamentarium of open, hybrid, and endovascular techniques which can be individualized to a patient's unique anatomy, surgical history, and concomitant lesions as well as the team's measured outcomes and experience.

Abstract
Background
Coarctation of the aorta coexists with other cardiac anomalies and has long‐term complications, including recoarctation, which may require intervention after the primary coarctation repair. This study aims to clarify the prevalence of and risk factors for interventions related to the coarctation complex as well as late mortality in a large contemporary patient population.
Methods and Results
The Swedish National Register of Congenital Heart Disease was used, which comprised 683 adults with repaired coarctation of the aorta. Analysis was performed on freedom from intervention thereafter at the coarctation site, aortic valve, left ventricular outflow tract, or ascending aorta. One hundred ninety‐six (29%) patients had at least 1 of these interventions. Estimated freedom from either of these interventions was 60% after 50 years. The risk of undergoing such an intervention was higher among men (hazard ratio, 1.6 [95% CI, 1.2–2.2]). Estimated freedom from another intervention at the coarctation site was 75% after 50 years. In women, there was an increase in interventions at the coarctation site after 45 years. Patients who underwent one of the previously mentioned interventions after the primary coarctation repair had poorer left ventricular function. Eighteen patients (3%) died during follow‐up in the register. The standardized mortality ratio was 2.9 (95% CI, 1.7–4.3).
Conclusions
Interventions are common after coarctation repair. The risk for and time of interventions are affected by sex. Our results have implications for planning follow‐up and giving appropriate medical advice to the growing population of adults with repaired coarctation of the aorta.
