Minimally invasive coronary artery bypass grafting using the skeletonized right gastroepiploic artery.

Objective: To evaluate the clinical outcomes of right gastroepiploic artery use in minimally invasive coronary artery bypass grafting.

Methods: A total of 428 patients who underwent minimally invasive coronary artery bypass grafting from February 2012 to February 2024 were included into this retrospective cohort study. The selection criteria for right gastroepiploic artery use included satisfactory artery size and length, significant stenosis (99% to 100%) of the right coronary artery, and unsuitable ascending aorta for partial clamping.

Evaluation of the patency rate and endothelialization of a poly-ε-caprolactone, nanofiber sheet-based vascular graft using a rat abdominal aortic implantation model.

Introduction: The global increase in cardiovascular diseases has resulted in an augmented development of artificial small-caliber vascular grafts used in bypass graft surgeries, such as coronary and distal artery bypass graft surgeries. However, no consensus exists regarding the best method for creating vascular grafts. Poly-ε-caprolactone (PCL) is a biocompatible and biodegradable material that has been widely studied as a scaffold for tissue regeneration, inclusive of vascular grafts.

Clinical outcomes of acute limb ischaemia caused by femoropopliteal stent thrombosis.

Background: Although femoropopliteal-specific stents have durable patency, stent thrombosis (ST) may occur, which can lead to acute limb ischaemia (ALI).

Aims: We aimed to investigate the clinical features and outcomes of ALI caused by femoropopliteal ST in patients with lower extremity artery disease.

Methods: This multicentre retrospective study included 499 patients with ALI - of whom 108 patients had ALI caused by femoropopliteal ST (ST-ALI) and 391 patients had ALI caused by other aetiologies (de novo ALI) - who underwent treatment between September 2011 and March 2023.

Impact of Antiplatelet Therapy on 5-Year Outcomes After Fractional Flow Reserve-Guided Deferral of Revascularization in Nonsignificant Obstructive Coronary Artery Disease.

Background: Because the clinical benefit of antiplatelet therapy (APT) for patients with nonsignificant coronary artery disease (CAD) remains poorly understood, we evaluated it in patients after fractional flow reserve (FFR)-guided deferral of revascularization.

Methods And Results: From the J-CONFIRM (Long-Term Outcomes of Japanese Patients with Deferral of Coronary Intervention Based on Fractional Flow Reserve in Multicenter Registry), we investigated 265 patients with deferred lesions who did not require APT for secondary prevention of cardiovascular disease. A 2-year landmark analysis assessed the relationship between APT at 2 years and 5-year major cardiac adverse events (MACE: composite of all-cause death, target vessel-related myocardial infarction, clinically driven target vessel revascularization).

Real-time Ripple technique: A case report on Ripple map for real-time identification of conduction gaps without first-pass pulmonary vein isolation.

This paper presents a novel approach to gap mapping in pulmonary vein isolation (PVI) for atrial fibrillation (AF) treatment, utilizing the real-time Ripple (RR) technique. Radiofrequency (RF) catheter ablation, particularly encircling PVI, is a common intervention for AF. Identifying left atrium-pulmonary vein conduction gaps is crucial for achieving PVI with minimal additional ablation if first-pass PVI is unsuccessful.

Improvement in respiratory function and exercise tolerance following video-assisted thoracoscopic diaphragm plication for symptomatic iatrogenic persistent diaphragm paralysis after radiofrequency catheter ablation.

Hemidiaphragm paralysis, a complication of catheter ablation for atrial fibrillation, can severely affect respiratory function and can lead to paradoxical breathing and dyspnea on exertion. A 75-year-old woman with iatrogenic diaphragm paralysis showed improved symptoms, respiratory function, and exercise tolerance after video-assisted thoracoscopic diaphragm plication.

Quantitative flow ratio versus fractional flow reserve for Heart Team decision-making in multivessel disease: the randomised, multicentre DECISION QFR trial.

Background: Vessel-level physiological data derived from pressure wire measurements are one of the important determinant factors in the optimal revascularisation strategy for patients with multivessel disease (MVD). However, these may result in complications and a prolonged procedure time.

Aims: The feasibility of using the quantitative flow ratio (QFR), an angiography-derived fractional flow reserve (FFR), in Heart Team discussions to determine the optimal revascularisation strategy for patients with MVD was investigated.
