Donor heart preservation is a major determinant of success in heart transplantation. Technological advances have led to optimizing the conditions of preservation, along with a more accurate assessment of the donor heart before transplantation. We herein describe two innovative technologies currently applied for cardiac preservation: uniform cooling preservation and normothermic ex-situ heart perfusion.

Blood pressure monitoring is one of the essential vital signs, and for a majority of patients, measuring it utilizing non-invasive techniques provides accurate values. However, there are situations in which the blood pressure requires more exact, specific, and reliable measurements.
FAQs
Its close relationship to the stapes and oval window makes anatomical orientation essential before manipulating the ossicular chain. A vessel that appears small or unexpected may occupy a surgically significant pathway. Identifying its position helps the surgeon distinguish vascular anatomy from operative structures and plan movements that limit disruption of the middle-ear anatomy.
Traction, cautery, or transection can disturb the vessel during work on the stapes and may produce intraoperative bleeding. These maneuvers can also place nearby auditory and facial nerve anatomy at risk when the artery is closely associated with the operative field. Avoiding unnecessary manipulation therefore supports controlled surgery and preservation of surrounding structures.
An embryonic artery that remains in the middle ear is the key finding requiring special attention. Its association with the stapes and oval window means that an unusual vascular structure in this region should be identified before the ossicular chain is manipulated. Recognition changes operative planning from routine instrument movement to deliberate vessel-preserving dissection.
Stapes Artery Preservation emphasizes preventing avoidable injury rather than treating bleeding after it occurs. The operative priority is to recognize the vessel, avoid unnecessary traction or energy use, and preserve its relationship with nearby structures. This approach can reduce intraoperative bleeding while maintaining a clearer, safer field around the stapes and oval window.
The process begins with accurate anatomical identification of the vessel and its course near the stapes and oval window. During ossicular-chain surgery, the surgeon then limits unnecessary traction, cautery, and transection. These precautions should be integrated into operative planning so that vessel preservation is considered before direct manipulation of the stapes.
The strategy is particularly relevant during stapes surgery, congenital middle-ear procedures, and operations addressing conductive hearing loss. Each setting may require work near the ossicular chain, where an unrecognized persistent stapedial artery could complicate manipulation. Applying careful anatomical identification in these procedures supports safer planning and preservation of middle-ear function.
Careful preservation can reduce intraoperative bleeding and help protect nearby auditory and facial nerve anatomy. It also supports preservation of middle-ear function when surgery involves the stapes or other ossicular structures. These benefits depend on recognizing the vessel’s course and avoiding unnecessary disruption rather than relying only on bleeding control after injury.
