ABSTRACT

Aortic root reconstruction during aortic root replacement for a patient with prosthetic valve endocarditis and aortic root abscess can be a difficult procedure with many possible complications. In this video case report, we describe our novel technique using a single bovine pericardial patch that avoids deep stitches or external sutures to support the friable annulus. Compared with more standard methods, this approach has shorter cross-clamp and cardiopulmonary bypass times and is less demanding technically.

ABSTRACT

Peyronie’s Disease (PD) is clinically characterized by the development of localized fibrous plaques, primarily on the tunica albuginea, especially on the dorsal area of the penis. These plaques are the hallmark feature of this condition, resulting in penile curvature, deformity, and painful erections for affected individuals. Although various nonsurgical treatment options exist, their overall effectiveness is limited. As a result, surgical intervention has become the ultimate choice for patients with severe penile curvature deformities and associated erectile dysfunction. Our research team has successfully employed a combined approach involving microscopic electric rotary grinding of the fibrous plaques and the use of tunica vaginalis or bovine pericardium as graft materials for the repairing of the defects of tunica albuginea in the treatment of PD. This approach has consistently yielded highly satisfactory results regarding the restoration of penile shape, with excellent cosmetic results and significantly improved sexual satisfaction. This protocol aims to present a comprehensive surgical management strategy utilizing electric rotary grinding of the plaques and repairing the defects of tunica albuginea by using the tunica vaginalis, which represents an optimal surgical strategy for treating PD.

ABSTRACT

About 280 000 heart valve replacements are performed worldwide every year. Since the first prosthetic valve implantation in 1952 there have been notable developments. There are a lot of types of prosthetic valves that can be summarized into two categories: biological prosthetic valves or mechanical prosthetic valves. Biological prostheses, made of bovine or porcine pericardium, homografts, or autografts, degenerate over time becoming dysfunctional. Mechanical prostheses have a potentially unlimited lifespan but require oral anticoagulation which can affect patients’ quality of life. Generally, biological prostheses are particularly suitable for elderly patients while mechanical prostheses for young people, with some distinctions. For example, in case of age <60 years, in the presence of preoperative oral anticoagulant therapy, metabolic syndrome, hemodialysis or hyperparathyroidism, a mechanical valve is the preference. The choice of the prosthesis in patients aged between 55 and 70 years is particularly challenging because the advantages and disadvantages of the two categories of prosthesis overlap in middle-aged patients. The choice of the prosthesis should be made after discussion with the surgeon, according to the patient’s preferences, and keeping in mind the pros and cons of biological and mechanical prostheses.
