Late erosion of Amplatzer Septal Occluder device 9 years after the implantation: a case report.

Cardiac erosion is a rare but life-threatening complication after the interventional closure of an atrial septal defect. We present the case of a patient who developed cardiac erosion 9 years after the placement of an Amplatzer Septal Occluder. The patient presented to our hospital with symptoms of tamponade.

Angiotensin Regulation of Vascular Homeostasis: Exploring the Role of ROS and RAS Blockers.

Extensive research has been conducted to elucidate and substantiate the crucial role of the Renin-Angiotensin System (RAS) in the pathogenesis of hypertension, cardiovascular disorders, and renal diseases. Furthermore, the role of oxidative stress in maintaining vascular balance has been well established. It has been observed that many of the cellular effects induced by Angiotensin II (Ang II) are facilitated by reactive oxygen species (ROS) produced by nicotinamide adenine dinucleotide phosphate (NADPH) oxidase.
