Summary
On-pump beating heart aortic valve replacement using retrograde coronary sinus (CS) warm blood perfusion is effective. This technique offers a viable surgical option, maintaining the heart's physiological condition during aortic valve replacement.
Area of Science:
- Cardiovascular Surgery
- Cardiac Anesthesia
- Cardiothoracic Surgery
Background:
- Assessing the efficacy of on-pump beating heart aortic valve replacement.
- Evaluating retrograde coronary sinus (CS) warm blood perfusion applicability.
Purpose of the Study:
- To evaluate the effectiveness and feasibility of on-pump beating heart aortic valve replacement.
- To analyze the use of retrograde coronary sinus (CS) warm blood perfusion during the procedure.
Main Methods:
- Prospective study of 14 patients undergoing aortic valve replacement with mechanical prosthesis.
- Utilized retrograde CS perfusion and pulmonary vein venting for surgical access.
Main Results:
- Good visualization and ease of operation achieved with retrograde CS perfusion.
- Favorable partial oxygen pressures in CS perfusion blood (288.5 mmHg).
- Low postoperative cardiac enzyme levels (CK-MB: 77.0 IU/L, Troponin T: 0.8 ng/mL) with no mortality or major complications.
Conclusions:
- On-pump beating heart aortic valve replacement with retrograde CS warm blood perfusion is a safe and effective surgical approach.
- This method preserves the heart's physiological state during aortic valve replacement surgery.

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...

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
