Delayed occluder displacement following patent ductus arteriosus closure successfully managed with thoracic endovascular aortic repair: a case report and literature review.

Interventional occlusion of Patent ductus arteriosus (PDA) is generally efficacious and complications such as delayed occluder displacement are infrequent. Herein, we report a case of 24-year-old female with a history of unsuccessful PDA closures, who subsequently experienced delayed occluder displacement into the left main pulmonary artery. Despite numerous unsuccessful catheter-based interventions, thoracic endovascular aortic repair (TEVAR) was successfully executed.

C-C Motif Chemokine 2 Regulates Macrophage Polarization and Contributes to Myocardial Infarction Healing.

Macrophages are crucial immune cells that play essential roles in the healing of myocardial infarction (MI), undergoing continuous polarization throughout this process. C-C motif chemokine 2 (CCL2) is a chemokine that regulates inflammatory responses during MI. However, the extent to which CCL2 influences macrophage polarization and MI healing remains incompletely understood.

Surgical Treatment & Long-term Follow Up of Giant Spherical Coronary Artery Aneurysm with Fistula to Left Ventricle: A Case Report.

Congenital fistula between the first diagonal branch of the coronary artery and left ventricle with a giant coronary artery aneurysm is extremely rare. We present the case of a 50-year-old asymptomatic male patient with such a condition that was diagnosed by transthoracic echocardiography, coronary computed tomography angiography, and coronary angiography. The patient was treated by surgical fistula closure under cardiopulmonary bypass.

A strongly adhesive hemostatic hydrogel for the repair of arterial and heart bleeds.

Uncontrollable bleeding is a major problem in surgical procedures and after major trauma. Existing hemostatic agents poorly control hemorrhaging from traumatic arterial and cardiac wounds because of their weak adhesion to wet and mobile tissues. Here we design a photo-reactive adhesive that mimics the extracellular matrix (ECM) composition.
