Impact of osteoporotic risk in women undergoing transcatheter aortic valve replacement
In this study, we aimed to investigate the osteoporotic risk in women with severe aortic stenosis and determined whether an OST could predict all-cause mortality following TAVR. The study population comprised 619 women who underwent TAVR. Compared to a quarter of patients with diagnosis of osteoporosis, 92.4% of participants were at high risk of osteoporosis based on OST criteria. When divided into tertiles based on OST values, patients in tertile 1 (lowest OST) displayed increased frailty, a higher incidence of multiple fractures, and greater Society of Thoracic Surgeons scores. Estimated all-cause mortality survival rate...

Very short-term tissue coverage of the CD34 antibody-covered sirolimus-eluting stent: an optical coherence tomography study
AbstractIt is well known that patients with acute myocardial infarction (AMI) have delayed vessel healing despite accelerated endothelial progenitor cells (EPC) mobilization. The COMBO stent is a unique biodegradable-polymer sirolimus-eluting stent with an anti-CD34 antibody coating which captures EPC and potentially promotes vessel healing. However, there are limited data about strut tissue coverage at the very short-term period after COMBO stent implantation. This was a prospective study to investigate strut tissue coverage within 1  month after COMBO stent implantation using optical coherence tomography (OCT). Struts f...

Guide extension proximal locking method: standardization of maximum backup force in percutaneous coronary intervention
AbstractWe developed the smallest diameter guide-extension catheter (GUIDE PLUS ® 5Fr) to enable a new technique, the guide-extension proximal locking method (GP-Lock), and assessed its efficacy in the present experimental and clinical study. Sufficient guide catheter backup is sometimes crucial for PCI. We developed the KIWAMI-Lock direct anchoring method to obtain the strong est backup force by locking a Kiwami® 4Fr child catheter (Terumo Corp. Tokyo, Japan) directly to the coronary artery by ballooning from outside the child catheter. However, this method is complicated due to the requirement for a child catheter. We ...

Volume-outcome relationship in complication-related mortality after percutaneous coronary interventions: an analysis on the failure-to-rescue rate in the Japanese Nationwide Registry
AbstractIn-hospital mortality following percutaneous coronary intervention (PCI) varies across institutions with different annual PCI volumes. The failure to rescue (FTR) rate, defined as the mortality rate following PCI-related complications, may account for the volume-outcome relationship. The Japanese Nationwide PCI Registry, a consecutive, nationally mandated registry between 2019 and 2020, was queried. The FTR rate is defined as ‘the number of patients who died following PCI-related complications’ divided by ‘the number of patients who experienced at least one PCI-related complication.’ Multivariate analysis w...

Physiology-guided PCI versus CABG for left main coronary artery disease: insights from the DEFINE-LM registry
AbstractThere have been no studies comparing clinical outcomes of physiology-guided revascularization in patients with unprotected left main coronary disease (ULMD) between percutaneous coronary intervention (PCI) vs. coronary artery bypass grafting (CABG). The aim of this study was to assess the long-term clinical outcomes between PCI and CABG of patients with physiologically significant ULMD. From an international multicenter registry of ULMD patients interrogated with instantaneous wave-free ratio (iFR), we analyzed data from 151 patients (85 PCI vs. 66 CABG) who underwent revascularization according to the cutoff value...

Impact of quantitative flow ratio on graft function in patients undergoing coronary artery bypass grafting
This study aimed to investigate whether preoperative QFR could discriminate arterial bypass function at 1  year after surgery. The PRIDE-METAL registry was a prospective, multicenter observational study that enrolled 54 patients with multivessel coronary artery disease. By protocol, left coronary stenoses were revascularized by CABG with arterial grafts, whereas right coronary stenoses were treated wit h coronary stenting. Follow-up angiography at 1 year after surgery was scheduled to assess arterial graft patency. QFR was performed using index angiography by certified analysts, blinded to bypass graft function. The prim...

Prediction of the debulking effect of rotational atherectomy using optical frequency domain imaging: a prospective study
This study determined the predictive accuracy of optical frequency domain imaging (OFDI) on debulking effects of rotational atherectomy (RA) and compared the predictive accuracy of OFDI catheter-based with Rota wire-based prediction methods. This prospective, single-center, observational study included 55 consecutive patients who underwent OFDI-guided RA. On pre-RA OFDI images, a circle, identical to the Rota burr was drawn at the center of the OFDI catheter (OFDI catheter-based prediction method) or wire (wire-based prediction method). The area overlapping the vessel wall was defined as the predicted ablation area (P-area...

Low incidence of restenosis after successful balloon pulmonary angioplasty in patients with chronic thromboembolic pulmonary hypertension
AbstractBalloon pulmonary angioplasty (BPA) is now a treatment option for patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH). However, the incidence of restenosis and long-term changes in vessel diameters in pulmonary arteries after BPA are unknown. The present study investigated the incidence of restenosis by measuring changes in vessel diameter after BPA. We reviewed 58 patients (168 lesions) with CTEPH who underwent single dilation for the target lesion (type A/B/C lesions) during BPA procedure followed by selective pulmonary angiography more than 6  months after the final BPA procedure. The...
