Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals1 dictates that rodent survival surgery be performed aseptically. Aseptic technique utilizes specific practices that minimize the contamination of the surgical site, including patient preparation, surgeon preparation, sterilization of instruments and other supplies, and the use of a clean and controlled environment. Presurgical planning,...

The purpose of this protocol is to demonstrate the placement of a delayed constricting device (an ameroid constrictor) around a coronary artery in a swine model. This device creates an ischemic area of the heart that is useful for studying new diagnostic imaging techniques and new methods of treatment.

Source: Suneel Dhand, MD, Attending Physician, Internal Medicine, Beth Israel Deaconess Medical Center The cardiac assessment is one of the core examinations performed by almost every physician whenever encountering a patient. Disorders of the cardiac system are among the most common reasons for hospital admission, with conditions ranging from myocardial infarction to congestive heart failure. Learning a complete and thorough cardiac examination is therefore crucial for any practicing physician.

The goal of this article is to describe how cardiac magnetic resonance can be used for the evaluation and diagnosis of a suspected cardiac thrombus. The method presented will describe data acquisition as well as the pre-procedure and post-procedure protocol.
FAQs
Cardiopulmonary bypass temporarily supports circulation while surgeons operate on the heart. This support allows the operative team to address cardiac structures under controlled conditions rather than relying on the heart to maintain circulation throughout the procedure. Its use is determined by the operation and the structures involved, and it is paired with measures intended to protect the heart and other organs.
A cardiac surgery technique becomes relevant when medication or a catheter-based approach cannot adequately address the problem. Operative access can expose the affected heart or great-vessel structure directly, allowing surgeons to repair tissue, restore blood flow, or place prosthetic material. Thus, the choice reflects the condition’s specific structural and therapeutic demands rather than a preference for surgery alone.
Repair preserves and corrects existing tissue, whereas replacement uses prosthetic material when the affected structure requires implantation. Restoring blood flow represents another objective, particularly when the operation addresses circulation through the heart or great vessels. Distinguishing these goals helps explain why cardiac surgery techniques vary substantially between patients and why the operative plan depends on the underlying disorder.
Planning begins with the condition to be addressed and the relevant heart or great-vessel structure. Surgeons then select an operative approach, determine whether temporary circulatory support is needed, and choose among tissue repair, blood-flow restoration, or prosthetic implantation. Throughout the operation, protection of the heart and other organs remains a central consideration.
They are used across several major categories: coronary artery disease, valve disorders, congenital heart defects, and aortic disease. These conditions differ in the structures and goals involved, so the technique may focus on repairing tissue, restoring blood flow, or replacing a structure with prosthetic material. This range explains the breadth of cardiac surgery within medicine.
Refinement of operative techniques has improved surgical precision, patient safety, recovery, and long-term cardiovascular outcomes. These gains matter because cardiac operations must address diseased structures while protecting the heart and other organs. In medicine, the value of a technique is therefore judged not only by whether it treats the immediate problem, but also by its effects on recovery and subsequent cardiovascular health.
