Pulmonary artery dissection is a rare and extremely dangerous disease with high mortality rates. It is one of the most serious complications of chronic pulmonary hypertension. It may be related to chronic pulmonary hypertension and pulmonary artery dilatation. Early diagnosis of pulmonary dissection is particularly important because of its high mortality. Once the symptoms worsen or severe deterioration of the disease occurs, imaging examination should be performed promptly for early diagnosis and timely treatment.

Introduction: Asthma is a complex condition characterized by airway inflammation. Interleukin-6 (IL-6) plays a significant role in asthma pathogenesis through its effects on T cells and its association with pro-inflammatory responses. Both lung and circulating IL-6 levels are elevated in asthma.

Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumour that rarely behaves malignant. We report a radical resection of a mediastinal AFH, which grew invasively into the pulmonary artery wall, was adherent to the posterior aorta and close to the main stem of the left coronary artery. A transection of the aorta was performed using cardiopulmonary bypass and cardioplegic arrest for a safe and radical removal that resulted in symptom relief.

Hydrogel bioadhesives with adequate wet adhesion and swelling resistance are urgently needed in clinic. However, the presence of blood or body fluid usually weakens the interfacial bonding strength, and even leads to adhesion failure. Herein, profiting from the unique coupling structure of carboxylic and phenyl groups in one component (N-acryloyl phenylalanine) for interfacial drainage and matrix toughening as well as various electrostatic interactions mediated by zwitterions, a novel hydrogel adhesive (PAAS) is developed with superior tissue adhesion properties and matrix swelling resistance in challenging wet conditions (adhesion strength of 85 kPa, interfacial toughness of 450 J m, burst pressure of 514 mmHg, and swelling ratio of <4%).

Objectives: To describe the workflow and value of three-dimensional rotational angiography (3DRA) in percutaneous pulmonary valve implantation (PPVI).
Background: 3DRA offers visualization of the entire topography in the chest and may enhance safety and reduce the risk for complications in PPVI through improved pre-procedural planning and per-procedural guidance.
Methods: All PPVI procedures with the use of 3DRA performed between August 2011 and December 2022 were reviewed.

Absent pulmonary valve syndrome (APVS) is a rare congenital anomaly characterized by rudimentary PV tissue with variable degrees of PV stenosis and regurgitant pulmonary blood flow. In most cases, it is associated with tetralogy of Fallot. In a minority of APVS cases, with an unknown frequency, intact ventricular septum (IVS), patent ductus arteriosus, and possible tricuspid atresia are present.
