Rapidly evolving angioplasty balloon techniques need continual evaluation for the type or frequency of balloon-related complications. We recently encountered a case where a new narrow shaft polyethylene terephthalate balloon completely separated from the catheter following circumferential rupture. The balloon was successfully retrieved using grasping forceps and a basket. Patterns of balloon rupture and subsequent management are discussed. Problems of this type were more frequent in the early days of balloon angioplasty, but have since become rare. Close surveillance of new low profile balloons is recommended to determine whether this represents an isolated occurrence or a return to the earlier experience.

Removal of a circumferentially torn stuck balloon from a calcified right ventricle to pulmonary artery conduit.

We report a case of right ventricle to pulmonary artery conduit angioplasty in which a valvuloplasty balloon ruptured circumferentially and was retained within the conduit. A high-pressure balloon was used to relieve the obstruction and free the ruptured balloon. The procedure was further complicated when the distal part of the balloon broke away from the proximal part during an attempt to retrieve it back into the femoral sheath.

Background: An all-inside endoscopic flexor hallucis longus (FHL) tendon transfer is indicated for the treatment of chronic, full-thickness Achilles tendon defects. The aim of this procedure is to restore function of the gastrocnemius-soleus complex while avoiding the wound complications associated with open procedures.
Description: This procedure can be performed through 2 endoscopic portals, a posteromedial portal (the working portal) and a posterolateral portal (the visualization portal).
Fracture properties of porcine versus human thoracic aortas from tricuspid/bicuspid aortic valve patients via symmetry-constraint Compact Tension testing.

Aneurysm rupture is a life-threatening event, yet its underlying mechanisms remain largely unclear. This study investigated the fracture properties of the thoracic aneurysmatic aorta (TAA) using the symmetry-constraint Compact Tension (symconCT) test and compared results to native and enzymatic-treated porcine aortas' tests. With age, the aortic stiffness increased, and tissues ruptured at lower fracture energy [Formula: see text].

Introduction: Combined anterior cruciate ligament (ACL) and meniscal tear patterns and their effect on knee stability have been widely researched, however, their evolution and repairability from time of injury have been scarcely addressed. When addressed with delay, meniscal lesions associated with ACL tears may increase in severity and irreparability. This study aims to investigate the incidence, rate and pattern of meniscus tears in the context of ACL deficient knees and to assess the meniscal condition in early versus late ACL reconstruction (ACLR).

Despite the discovery and prevalent clinical use of potent lipid-lowering therapies, including statins and PCSK9 inhibitors, cardiovascular diseases (CVD) caused by atherosclerosis remain a large unmet clinical need, accounting for frequent deaths worldwide. The pathogenesis of atherosclerosis is a complex process underlying the presence of modifiable and non-modifiable risk factors affecting several cell types including endothelial cells (ECs), monocytes/macrophages, smooth muscle cells (SMCs) and T cells. Heterogeneous composition of the plaque and its morphology could lead to rupture or erosion causing thrombosis, even a sudden death.
