Association of Below-the-Knee Lesions With Occult Coronary Artery Disease in Patients With Lower Extremity Artery Disease Undergoing Endovascular Therapy

Kazuki Haraguchi, Hisashi Koga, Tomohiro Kawasaki

Background: In patients with lower extremity artery disease (LEAD), coexisting coronary artery disease (CAD) is common, but the angiographic features associated with occult CAD remain poorly characterized. We performed a hypothesis-generating angiographic phenotyping analysis to examine whether lower extremity lesions treated with …

Optical Coherence Tomography Characterization of Coronary Lithotripsy Following Atherectomy for Treatment of Severely Calcified Lesions

Yohei Sotomi, Nehiro Kuriyama, Yutaka Tanaka, Seiji Yamazaki et autres

BACKGROUND: A combined strategy of atherectomy followed by intravascular lithotripsy (dual-prep strategy) for severely calcified lesions may optimize stent deployment, but mechanistic evidence from prospective optical coherence tomography (OCT) imaging is limited. This study was designed to comprehensively characterize patterns of calcium …

Noninvasive Evaluation of Cerebrospinal Fluid Protein Concentration Using Amide Proton Transfer-weighted Imaging

Tomohiro Kawasaki, Khin Khin Tha, Masami Yoneyama, Kinya Ishizaka et autres

Motivation: Protein concentration in cerebrospinal fluid (CSF) is traditionally measured through lumbar puncture, an invasive procedure. Currently, no noninvasive imaging methods exist to evaluate protein levels in CSF. Goal(s): To explore the feasibility of using Amide Proton Transfer (APTw) imaging to assess …

Percutaneous Coronary Intervention Outcomes for Chronic Total Occlusion in Patients on Dialysis: Analysis of the Japanese CTO‐PCI Expert Registry

Mayu Sakuma, Yuji Oikawa, Koichi Kishi, Yoshiaki Ito et autres

BACKGROUND: Patients undergoing dialysis are at a high risk of cardiovascular death, and the prevalence of coronary complex lesions is high. AIMS: This study aimed to analyze the characteristics, outcomes, and adverse events of chronic total occlusion (CTO)-percutaneous coronary intervention (PCI) in …

Dual-Prep registry: atherectomy devices and intravascUlAr lithotripsy for the PREParation of heavily calcified coronary lesions registry

Masato Nakamura, Nehiro Kuriyama, Yutaka Tanaka, Seiji Yamazaki et autres

Evaluation of calcified lesions by intravascular imaging has revealed that atherectomy devices have only limited impact. However, subsequent use of coronary intravascular lithotripsy (IVL) may increase treatment effectiveness without increasing risk of complications. This study was designed to evaluate the safety and …
