Insights
Clampless cardioplegia offers a vital alternative for myocardial protection in cardiac surgery when aortic cross-clamping is not feasible. This approach ensures a quiescent heart and bloodless field, with no observed cardiac functional changes in four patients.
Area of Science:
- Cardiovascular Surgery
- Cardiac Anesthesia
- Cardiothoracic Medicine
Background:
- Myocardial protection is critical during cardiac surgery.
- Standard cardioplegia delivery is challenging in certain patient populations.
- Alternative methods are needed for patients where aortic cross-clamping is not possible.
Purpose of the Study:
- To develop a policy and protocol for clampless or systemic cardioplegia.
- To evaluate the feasibility and safety of this technique in specific surgical scenarios.
- To report on the peri-operative outcomes of patients receiving clampless cardioplegia.
Main Methods:
- Development of a specific protocol for clampless cardioplegia administration.
- Application of the protocol in four distinct patient cases.
- Peri-operative monitoring including post-operative echocardiography.
Main Results:
- Successful implementation of clampless cardioplegia in four patients.
- No significant changes in cardiac function were detected by post-operative echocardiograms.
- No peri-operative complications were reported in the treated patients.
Conclusions:
- Clampless cardioplegia is a viable alternative for myocardial protection when standard methods are contraindicated.
- This protocol provides a safe and effective option for achieving a bloodless field and quiescent heart.
- Further studies may explore broader applications and long-term outcomes.
Abstract:
Myocardial protection is of the utmost importance during cardiac surgery. At times, there are patients who present to the operating room who make the typical use of cardioplegia difficult or impossible. For these patients, a separate protocol and process must be in place. "Clampless cardioplegia" is an option when the ascending aorta cannot be cross-clamped, but the surgeon needs a bloodless field with a quiescent heart. This study reports on the process of developing a policy and protocol for utilizing clampless or systemic cardioplegia. Four case reports of patients who received clampless or systemic cardioplegia and their peri-operative courses are described. These four patients showed no cardiac functional change by post-operative echocardiogram and no peri-operative complications are reported.

Null and Alternative Hypotheses
The null hypothesis, denoted by H0 is a statement of no difference between the variables—they are not related. This can often be considered the status quo. As a result if you cannot accept the null, it requires some action.
The alternative hypothesis, denoted by H1 or Ha, is a claim about the...
