Background The detection of in-stent restenosis (ISR) with coronary CT angiography (CCTA) is challenging, but CT perfusion (CTP) has demonstrated improved diagnostic accuracy over CCTA in patients with stents. However, there are limited data on the performance of dynamic CTP, which allows noninvasive adjudication of regional myocardial blood flow. Purpose To compare the diagnostic performance of regadenoson-stress dynamic CTP with that of CCTA, using fractional flow reserve (FFR) and the index of microvascular resistance (IMR) as reference standards for epicardial coronary circulation and coronary microcirculation, respectively.

Article Synopsis
- Transcatheter Pulmonary Flow Restrictors (TPFRs) are innovative devices for managing pulmonary blood flow in congenital heart disease, yet there is a lack of detailed studies examining their variety and crucial design features.
- * The review consolidates current knowledge on TPFRs, highlights significant design considerations, identifies gaps in medical practice, and suggests future research avenues to improve these devices.
- * An analysis of 82 TPFR implants revealed challenges like complications with microvascular plugs, including issues with sizing, device migration, and thrombosis, while emphasizing the need for devices that can be safely removed and reduce risks like embolization and inflammation.
Microvascular Plug Embolization of Anterior Spinal Artery Bearing Segmental Arteries Prior Aortic Stenting: Technique and Safety.

Purpose: This study aims to present our experience with superselective embolization of the anterior spinal artery-bearing segmental artery (ASAbSA) using a microvascular plug (MVP) during the minimally invasive segmental artery coil embolization (MISACE) procedure prior endovascular repair of the thoracoabdominal aortic aneurysms.
Methods: We retrospectively evaluated all MISACE procedures performed between May 2018 and July 2023, where MVP was deployed into an angiographically confirmed ASAbSA. Data were analyzed regarding interventional details, technical aspects, and safety protocols.
Engineering Biomimetic Microvascular Capillary Networks in Hydrogel Fibrous Scaffolds via Microfluidics-Assisted Co-Axial Wet-Spinning.

The microvascular bed plays a crucial role in establishing nutrient exchange and waste removal, as well as maintaining tissue metabolic activity in the human body. However, achieving microvascularization of engineered 3D tissue constructs is still an unsolved challenge. In this work, we developed biomimetic cell-laden hydrogel microfibers recapitulating oriented microvascular capillary-like networks by using a 3D bioprinting technique combined with microfluidics-assisted coaxial wet-spinning.

Adequate vascularization essential for delivering nutrients critical to wound healing, yet impaired angiogenesis is a major barrier in diabetic wound repair. This study investigates the impact of hyaluronic acid on interpenetrating network sponge scaffolds derived from an acellular dermal matrix, with the aim of enhancing vascularization and healing of diabetic wounds via photothermal warm bath therapy. We prepared three-dimensional porous sponges (HPD@DFO) using molecular interpenetration and ion crosslinking of porcine acellular dermal matrix (PADM), hyaluronic acid, and polydopamine nanoparticles loaded with deferoxamine mesylate (PDA@DFO).
