Penetrating heart injuries can be lethal. Here we report a case of self-inflicted cardiac injury with glass fragments by a psychiatric patient. The patient presented with cardiogenic shock and was initially treated surgically for a large pneumothorax and cardiac tamponade. A few days later she presented with dyspnoea and hypotension. An echo-Doppler study was performed and an acquired post-traumatic ventricular septal defect (VSD) with left-to-right shunt was diagnosed. The patient was transferred to theatre where the defect was successfully repaired. Post-traumatic VSD is a rare complication of penetrating heart injuries and has a tendency to present late. Follow up of such cases is recommended with repeat echocardiography.

Pneumopericardium (PPC) is defined by the presence of gas in the pericardial cavity, often leading to cardiac tamponade and a high mortality rate. This report describes a case involving a 33-year-old man found deceased a few meters from a knife, his clothes intact, with no resuscitation attempt made. A knotted scarf was tightly fastened around his neck, without ligature mark.

Background And Aims: When dealing with severely calcified lesions in endovascular therapy (EVT) for lower extremity artery disease (LEAD), navigating through severely calcified chronic total occlusion (CTO) using hard-tip guidewires can be challenging. To address this issue, we employed a novel highly intensive penetration (HIP) technique. This technique involves modifying the tail of a 0.

Gene therapy targeting ischemic heart disease is a promising therapeutic avenue, but it is mostly restricted to viral-based delivery approaches which are limited due to off-target immunological responses. Focused ultrasound presents a non-viral, image-guided technique in which circulating intravascular microbubble contrast agents can reversibly enhance vascular permeability and gene penetration. Here, we explore the influence of flow rate on the microbubble-assisted delivery of miR-126, a potent pro-angiogenic biologic, using a custom acoustically coupled pressurized mesenteric artery model.

Myocardial infarction (MI) is the leading cause of morbidity and mortality worldwide. Curcumin has been observed to significantly reduce pathological processes associated with MI. Its clinical application is limited due to its low bioavailability, rapid degradation, and poor solubility.

Heart disease is a significant global health issue. Traditional methods for heart rate monitoring typically require close physical contact, which limits the continuity and convenience of monitoring. To achieve real-time, non-contact heartbeat monitoring, researchers have introduced millimeter-wave radar technology.
