Summary
Aortic arch repair on a beating heart reduces myocardial ischemic time, leading to less heart damage and faster recovery in pediatric patients. This technique is safe and feasible.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiac Surgery
- Thoracic Surgery
Background:
- Aortic arch repair (AAR) traditionally involves aortic cross-clamping.
- Beating-heart techniques may improve postoperative cardiac function by reducing cross-clamping duration.
Purpose of the Study:
- To evaluate the feasibility and safety of AAR on a beating heart with selective myocardial perfusion.
- To compare outcomes between cardioplegic arrest and beating-heart AAR during biventricular repair.
Main Methods:
- A single-center review of 24 pediatric patients undergoing AAR during biventricular repair.
- Patients were operated on cardiopulmonary bypass (CPB) with antegrade cerebral perfusion (ACP).
- Comparison between 13 patients with cardioplegic arrest (group 1) and 11 with beating-heart repair (group 2).
Main Results:
- No statistical difference in CPB, AAR, or ACP durations between groups.
- Significantly lower cardioplegic arrest time in group 1 (34 ± 13 min) vs. group 2 (76 ± 11 min).
- Reduced myocardial ischemic damage in group 2, indicated by lower troponin T and CK-MB levels, and shorter inotropic/ventilatory support times.
Conclusions:
- Pediatric aortic arch correction on a beating heart with selective myocardial perfusion is technically feasible and safe.
- Reducing myocardial ischemic time effectively minimizes myocardial damage.
- This approach offers enhanced patient recovery.

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:15Aortic 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...
01:25Aortic 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...
