Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A surgical airway procedure is indicated when other forms of endotracheal intubation have failed and ventilation is worsening or not possible. This is the feared "can't intubate, can't ventilate" scenario, and in the emergency setting, cricothyrotomy is the surgical procedure of choice. Cricothyrotomy is preferred over tracheotomy because of the lower risk of complications, the predictable anatomy...

Standardized Technique of Aortic Valve Re-implantation for Valve-sparing Aortic Root Replacement

2017
Valve-sparing aortic root replacement has the advantage of preserving the patient's own aortic valve. The complexity of the reported techniques to date restricts their use to a limited number of cardiac surgeons. This protocol describes step-by-step a standardized technique reproducible by a greater number of cardiac surgeons.

In order to understand the cellular and molecular mechanisms underlying neotissue formation and stenosis development in tissue engineered heart valves, a murine model of heterotopic heart valve transplantation was developed. A pulmonary heart valve was transplanted to recipient using the heterotopic heart transplantation technique.
FAQs
The implant’s collapsible design allows it to travel through the access route and then expand at the diseased valve. Expansion anchors the prosthesis within the native valve, helping keep it stable while blood passes through. Imaging guidance is important because it supports positioning before expansion, when placement determines whether the replacement can function effectively during the cardiac cycle.
Once deployed, the prosthetic valve is intended to reproduce one-way flow by opening and closing with the heartbeat. This action addresses the mechanical problem created by severe stenosis or other valve dysfunction, where forward flow is impaired. Restoring more effective flow can improve cardiac performance and may lessen symptoms associated with the diseased valve.
Percutaneous Valve Implantation differs from conventional open-heart valve surgery mainly in how the replacement is delivered. A catheter-based approach avoids the larger surgical access associated with open surgery and therefore reduces surgical trauma. This distinction is particularly relevant when conventional surgery presents substantial risk, because it can broaden the range of patients considered for valve replacement.
During the procedure, clinicians guide the collapsed prosthesis through a blood vessel or another access route toward the diseased valve. Imaging is used to monitor its location and support accurate positioning. The device is then expanded so it anchors within the native valve. These coordinated steps connect access, navigation, placement, and deployment in a single treatment pathway.
The principal clinical settings are severe valve stenosis or valve dysfunction. The approach is especially relevant for patients who may face substantial risk with conventional valve surgery. In that context, percutaneous valve implantation provides an additional treatment option rather than requiring every patient to undergo the same surgical approach.
By re-establishing more effective one-way blood flow, the procedure can improve cardiac performance and symptoms. Its minimally invasive delivery also reduces surgical trauma compared with conventional open-heart surgery. These outcomes explain why the approach has expanded treatment options, while its clinical value remains tied to correcting significant valve disease.
