Immunoglobulin (Ig)G4-related disease affects nearly every organ, and its clinical course varies depending on the involved organ; however, its occurrence in the mediastinum is rarely reported.

Choice of the prosthetic valve in patients aged between 55 and 70 years
G Ital Cardiol (Rome). 2024 Apr;25(4):252-261. doi: 10.1714/4244.42206.
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.

Model for predicting the recurrence of atrial fibrillation after monopolar or bipolar radiofrequency ablation in patients with AF and mitral valve disease
This study aimed to identify the risk factors for postoperative atrial fibrillation in patients with valvular atrial fibrillation, and establish predictive models of atrial fibrillation recurrence.
Spontaneous retroperitoneal haemorrhage after pulmonary endarterectomy surgery
Spontaneous retroperitoneal hematoma (SRH) is a rare complication of anticoagulation therapy. Presentation may vary from limb paresis to hypovolemic shock due to blood loss. The optimal treatment is controvers… Read More

Pulmonary artery sarcoma affecting the pulmonary valve mistaken as pulmonary vasculitis: a case report and comparative literature review
Pulmonary arterial sarcomas (PAS) are rare aggressive tumours occurring mainly in the pulmonary trunk. We report a case of PAS involving the pulmonary trunk wall and valve, with uniform wall thickening which r… Read More
