Abstract Background Loeys-Dietz Syndrome (LDS) is a connective tissue disorder caused by mutations in the TGFBR1 or TGFBR2 genes, leading to significant cardiovascular complications, particularly aortic aneurysms and dissections. Due to the progressive nature of these issues, patients often require multiple cardiac interventions throughout their lives, although this has not been comprehensively reviewed in the literature. Purpose This study aims to review trends in cardiac interventions in LDS patients to better understand the surgical course these patients go through in their lives. Methods A retrospective analysis was conducted on a cohort of individuals diagnosed with LDS at our institution. Medical records were reviewed for data on demographics and types of interventions (e.g., aortic surgeries, valve procedures) were collected. Descriptive statistics were used to analyze the frequency of interventions with comparisons made between intervention types. Results A total of 94 patients with LDS were included in the study. Among them, 69 patients (73.4%) had an ascending aortic aneurysm, and 13 patients (14%) had a type A aortic dissection. A total of 60 patients underwent aortic root replacement surgery due to aneurysm or dissection, with 10 patients (11%) having the procedure following the occurrence of a dissection. Mitral valve prolapse (MVP) was found in 34 patients (36%). Valvular interventions were performed as follows, with some patients undergoing repairs on multiple valves: 12 patients (13%) had mitral valve repair, 10 patients (11%) had tricuspid valve repair, and the aortic valve was the most intervened upon, with 37 patients (39.5%) undergoing either replacement or repair. In total, 45 patients (48%) underwent at least one valvular intervention. Additionally, 4 patients (4.5%) underwent ventricular septal defect (VSD) closure, 3 (3.5%) underwent atrial septal defect (ASD) closure, and 3 (3.5%) had both defects closed. 29 patients (31%) had a patent foramen ovale, with 17 of these patients (59%) undergoing PFO closure. Finally, 16 patients (17%) underwent coronary artery bypass grafting (CABG). Conclusion Patients with LDS often require multiple surgeries and interventions throughout their lives due to the progressive nature of the disease and its impact on the cardiovascular system. The high incidence of aortic aneurysms, dissections, and valvular abnormalities necessitates frequent surgical management, with many patients undergoing interventions such as aortic root replacement, valve repairs, and septal defect closures. Given the complex and multifaceted cardiovascular involvement in LDS, close monitoring and timely intervention are crucial for optimizing outcomes and improving quality of life for these patients.
