Internal lung surface area (ISA) is a critical criterion for assessing lung morphology and physiology in lung diseases and injury-induced alveolar regeneration. We describe here a standardized method that can minimize the measurement bias for ISA in both lung pneumonectomy and prosthesis implantation mouse models.

Full-root aortic valve replacement by stentless aortic xenograft is a viable option in patients with small aortic roots. We describe, a technique for the full-root implantation of stentless aortic xenografts, with emphasis on the management of the proximal suture line and coronary anastomoses, and discuss its limitations and alternative options.

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.
FAQs
The prosthesis is positioned at the site of a diseased valve so it can regulate movement of blood between cardiac chambers or from the heart into a major artery. By restoring controlled forward flow, implantation addresses the abnormal circulation created by stenosis or regurgitation and can support improved cardiac function after the procedure.
Mechanical and bioprosthetic valves represent the two principal prosthesis options described for implantation. Their distinction is clinically important because prosthesis selection influences long-term management, including anticoagulation considerations and durability assessment. Clinicians weigh these factors alongside the involved valve and the patient’s condition when planning treatment and follow-up.
Stenosis restricts effective forward blood flow through the valve, whereas regurgitation reflects ineffective closure and backward flow. Implantation aims to correct the resulting disruption in circulation by providing a prosthesis that regulates passage in the intended direction. Successful treatment may relieve symptoms and reduce complications associated with progressive valve disease.
The involved heart valve and the patient’s condition help determine both prosthesis selection and the procedural strategy. Clinicians also consider whether a mechanical or bioprosthetic option is appropriate and whether open-heart surgery or a catheter-based approach should be used. These decisions establish the framework for implantation, anticoagulation planning, and later durability assessment.
Valve prosthesis implantation may be performed through open-heart surgery or by a catheter-based approach. In either case, procedural planning must account for the target valve and the patient’s condition, while the prosthesis is positioned to regulate blood flow at the affected site. The selected approach provides the pathway for restoring valve function.
Follow-up focuses on the factors that determine ongoing prosthesis management and patient outcomes. Clinicians assess durability over time and use the prosthesis type to guide anticoagulation considerations. Continued evaluation is important because implantation is part of a broader treatment plan intended to maintain effective blood flow and address complications linked to progressive valve disease.
The procedure is considered when damaged or diseased heart-valve function causes clinically important stenosis or regurgitation. Its potential benefits include symptom relief, improved cardiac function, and reduced complications associated with progressive valve disease. The choice of prosthesis and access route depends on the affected valve and the patient’s condition.
Outcomes are evaluated through the intended effects of the prosthesis: more effective one-way blood flow, relief of symptoms, and improved cardiac function. Longer-term assessment also examines prosthesis durability and management needs such as anticoagulation. Together, these measures help clinicians judge how well the implanted valve is addressing the underlying valve disease.
