Summary
The secondary Ross procedure offers better long-term survival and fewer reoperations compared to the primary Ross procedure in children. This suggests a delayed Ross procedure after initial aortic valve repair may be more beneficial.
Area of Science:
- Pediatric cardiac surgery
- Aortic valve replacement
- Autograft procedures
Background:
- The Ross procedure is a surgical technique for aortic valve replacement in children.
- It can be performed as a primary operation or a secondary procedure following prior aortic valve surgery.
Purpose of the Study:
- To compare the outcomes of primary versus secondary Ross procedures in pediatric patients.
- To evaluate long-term survival and freedom from reoperation between the two groups.
Main Methods:
- Retrospective analysis of 140 pediatric patients undergoing the Ross procedure between 1995 and 2018.
- Comparison of outcomes between primary and secondary Ross procedure groups.
- Propensity score matching was used to control for baseline characteristics and risk factors.
Main Results:
- In the matched cohort, 10-year survival was higher in the secondary Ross group (96.8%) compared to the primary Ross group (90.0%) (p=0.04).
- Freedom from autograft reoperation at 10 years was significantly better in the secondary Ross group (97.0%) versus the primary Ross group (82%) (p=0.03).
- No significant differences in survival or reoperation were noted in the unmatched cohort.
Conclusions:
- The secondary Ross procedure demonstrates superior long-term survival and freedom from autograft reoperation compared to the primary Ross procedure.
- Considering aortic valve repair followed by a delayed Ross procedure may enhance long-term outcomes.

212
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...

242
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...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

01:15Aortic Regurgitation I: Introduction
277
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...

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...

A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...
