Background:

We evaluated the long-term outcomes of children who underwent aortic valve (AoV) repair after infancy.

Methods:

A retrospective, single institutional study of all patients aged ≥1 year old who underwent primary AoV repair between 1980 and 2024 was performed (N=326).

Results:

Median age at AoV repair was 9.4 (IQR,4.8-14.2) years. Repair was achieved without patch material in 49.7% (162/326) of patients. Early mortality was 0.61% (2/326). Late death was 1.85%, (6/324). Median follow-up was 9.04 (IQR,3.4-16.6) years. Kaplan-Meier estimated survival at 10, 15 and 20 years was 98.4%, 97.9% and 94.9%. Freedom from AoV reoperation at 5, 10, 15 and 20 years was 85.6%, 74.1%, 59.1% and 55.0%. Freedom from AoV replacement (AVR) at 5, 10, 15 and 20 years was 92.2%, 79.5%, 65.7% and 61.7%. Twenty-year freedom from prosthetic AVR was 79.1%. During follow-up, 83 patients (25.5%, 83/326) underwent 101 AoV reoperations including 26 redo repairs, 35 Ross operations and 40 prosthetic AVRs. Independent risk factors for AVR were previous balloon aortic valvuloplasty [HR:2.34 (95%CI 1.27-4.30), p=0.006], AoV repair requiring CardioCel patch [HR:4.30 (95%CI 1.89-9.74), p<0.001] and subcommissural annuloplasty [HR:3.37 (95%CI 1.56-7.28), p=0.002].

Conclusion:

In children who underwent AoV repair after infancy, 15-year freedom from AoV reoperation or replacement was 59% and 66% respectively, with most undergoing either a subsequent Ross operation or redo AoV repair. Thus, in the lifelong management of AoV disease in children after infancy, a strategy of initial AoV repair allowed the majority of patients to progress through childhood without further AoV surgery and defers prosthetic AVR well into adult life.

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Aortic Regurgitation I: Introduction

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
