Tunable Regional Targeting of Self‐Assembling Peptide Nanomaterials in Acute Myocardial Infarction

open access: yesAdvanced NanoBiomed Research, EarlyView.
In a rat model of acute myocardial infarction, intravascular delivery of peptide nanofibers with a collagen‐targeting peptide bound to the infarct vasculature while globular peptide nanoparticles penetrated into the infarct area. This study demonstrated that size, shape, and surface chemistry of nanomaterials control the delivery location within the ...

Drug‐coated balloons: From conventional designs to next‐generation innovations in vascular therapy

open access: yesBMEMat, EarlyView.
This review traces the evolution of drug‐coated balloons (DCBs) from conventional designs to next‐generation platforms. We highlight innovations in balloon engineering, coating technologies, and therapeutic agents that enhance localized drug delivery while addressing challenges in efficiency, safety, and biocompatibility for vascular and emerging non ...

Functional Versus Anatomic Assessment of Myocardial Bridging by Intravascular Ultrasound: Impact of Arterial Compression on Proximal Atherosclerotic Plaque

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundThe presence of a myocardial bridge (MB) has been shown to promote atherosclerotic plaque formation proximal to the MB, presumably because of hemodynamic disturbances provoked by retrograde blood flow toward this segment in cardiac systole.

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

Intravascular ultrasound evaluation of pulmonary hypertension in high-altitude patients with ventricular septal defect: a case report

open access: yesJournal of Medical Case Reports
Background High-altitude pulmonary hypertension is a rare but serious condition, particularly in individuals with congenital heart disease. Patent ductus arteriosus is a common congenital defect that may progress to irreversible pulmonary hypertension if

A case with a large intracoronary mobile mass diagnosed with a calcified thrombus using optical frequency domain imaging and intravascular ultrasound

open access: yesSAGE Open Medical Case Reports, 2017
Objectives: A calcified thrombus is rare, but needs to be recognized and to be differentiated from calcified nodule. Methods: We report a case of acute coronary syndrome and a large intracoronary mobile mass, which was identified as a calcified thrombus ...
