Article Synopsis
  • The study evaluated the clinical outcomes and performance of the SAPIEN 3 Ultra RESILIA (S3UR) valve compared to the SAPIEN 3 (S3) valve in patients undergoing transcatheter aortic valve replacement (TAVR).
  • Results showed no significant differences in in-hospital complications like death and vascular issues between the two groups, but the S3UR group had a lower incidence of paravalvular leakage and better pressure gradients.
  • The findings suggest that while procedural complications are similar, the S3UR valve performs better, especially in smaller sizes, addressing some limitations of existing balloon-expandable valves.

Background: Despite the effectiveness of the retrograde approach for chronic total occlusion (CTO) lesions, there are no standardized tools to predict the success of retrograde percutaneous coronary intervention (PCI).

Objectives: The aim of this study was to develop a prediction tool to identify CTO lesions that will achieve successful retrograde PCI.

Methods: This study evaluated data from 2,374 patients who underwent primary retrograde CTO-PCI and were enrolled in the Japanese CTO-PCI Expert Registry between January 2016 and December 2022 (NCT01889459).

Article Synopsis
  • The study investigates the impact of pre-existing and new onset left bundle branch block (LBBB) on clinical outcomes in patients undergoing transcatheter aortic valve replacement (TAVR).
  • Out of nearly 6,000 patients, 4.6% had pre-existing LBBB, while 27.6% developed new onset LBBB post-procedure.
  • Results show that pre-existing LBBB was linked to significantly higher rates of all-cause and cardiovascular mortality compared to both the new onset LBBB and no LBBB groups, highlighting the need for careful monitoring of these patients.

Background: The extent of cardiac damage and its association with clinical outcomes in patients undergoing transcatheter edge-to-edge repair (TEER) for degenerative mitral regurgitation remains unclear. This study was aimed to investigate cardiac damage in patients with degenerative mitral regurgitation treated with TEER and its association with outcomes.

Methods: We analyzed patients with degenerative mitral regurgitation treated with TEER in the Optimized Catheter Valvular Intervention-Mitral registry, which is a prospective, multicenter observational data collection in Japan.

Aims: A considerable proportion of candidates for transcatheter aortic valve implantation (TAVI) have underlying heart failure (HF) with preserved ejection fraction (HFpEF), which can be challenging for diagnosis because significant valvular heart disease should be excluded before diagnosing HFpEF. This study investigated the long-term prognostic value of the pre-procedural HFPEF score in patients with preserved ejection fraction (EF) undergoing TAVI.

Methods And Results: Patients who underwent TAVI between October 2013 and May 2017 were enrolled from the Optimized CathEter vAlvular iNtervention-Transcatheter Aortic Valve Implantation Japanese multicentre registry.

Article Synopsis
  • Transcatheter edge-to-edge mitral valve repair (TEER) is gaining attention as a treatment for significant secondary mitral regurgitation, especially in patients with chronic heart failure.* -
  • The study analyzed 1,517 patients from the OCEAN-Mitral registry to identify factors linked to cardiac death within a year following TEER, finding that previous heart failure admissions, use of intravenous inotropes, and high plasma B-type natriuretic peptide levels were significant predictors.* -
  • Researchers created a new risk-scoring system based on these factors, successfully distinguishing different levels of 1-year cardiac mortality risk (16%, 8%, and 4%), which can help clinicians tailor treatment strategies.*

Article Synopsis
  • Transcatheter edge-to-edge repair (TEER) with MitraClip is a minimally invasive treatment for mitral regurgitation (MR), but comprehensive data on its safety and effectiveness is limited, especially for the fourth-generation (G4) system.
  • The OCEAN-Mitral Registry, involving 21 centers in Japan, enrolled 2,150 patients with MR to analyze their characteristics, procedural details, and clinical outcomes between April 2018 and June 2021.
  • Findings indicated that 94.6% of patients achieved acute procedural success with both the G2 and G4 systems, although the G4 system showed promise for improved outcomes with a multidisciplinary approach.

Article Synopsis
  • Intracoronary imaging enhances clinical outcomes for complex coronary bifurcation lesions (CBLs), but the influence of Medina classification on these outcomes is not well understood.
  • This study analyzed data from four prior studies involving 763 CBLs treated with drug-eluting stents and imaging guidance, focusing on major adverse cardiac events (MACE) at a one-year follow-up.
  • The results showed that the 0-0-1 Medina subtype had significantly higher risks for MACE and target lesion revascularization compared to the 0-1-0 subtype, while similar outcomes were observed in true and non-true CBLs except for the 0-0-1 lesions.

Background: Individuals with heart failure displaying supra-normal left ventricular ejection fraction (snLVEF) may exhibit less favorable clinical outcomes in contrast to their counterparts with normal left ventricular ejection fraction (nLVEF). The distinctive characteristics and mid-term prognosis of individuals with severe aortic stenosis and snLVEF following transcatheter aortic valve replacement (TAVR) remain enigmatic.

Methods: Among 7393 patients diagnosed with severe aortic stenosis who underwent TAVR between 2013 and 2019 and were enlisted in the optimized transcatheter valvular intervention (OCEAN-TAVI) multicenter registry (UMIN000020423), we selected patients with left ventricular ejection fraction (LVEF) ≥ 50%.

Intestinal Atp8b1 dysfunction causes hepatic choline deficiency and steatohepatitis.

Nat Commun

November 2023

Laboratory of Molecular Pharmacokinetics, Graduate School of Pharmaceutical Science, The University of Tokyo, Tokyo, Japan.

Article Synopsis
  • Choline is vital for health, and its deficiency can lead to a liver condition called steatohepatitis, primarily due to issues with how phosphatidylcholine is processed in the intestines.
  • Researchers studied mice lacking the Atp8b1 gene, which is important for lipid transport in intestinal cells, and found that these mice developed steatohepatitis in just four weeks.
  • Supplementing choline in the diet of these mice helped reverse their liver condition, suggesting that similar choline supplementation might benefit patients with ATP8B1-related liver issues.

Article Synopsis
  • Chronic total occlusion (CTO) PCI is complex and varies in success rates among the three major coronary arteries due to differences in lesion characteristics.
  • The study analyzed 6,408 first-attempt CTO patients from a Japanese registry to identify predictors of unsuccessful PCI and developed a difficulty score for surgical outcomes.
  • Results showed that success rates were lowest for the left circumflex artery, with key differences in predictors of failure across arteries, and the new difficulty score outperformed the J-CTO score in forecasting PCI success.

Article Synopsis
  • * Analyzing 111 lesions from 168 patients, the research found three key geometric parameters—SB diameter, BP-CT length, and dPOC—that were significant predictors of SB compromise, with corresponding cutoff values established.
  • * The results revealed that as the OCT risk score increased based on these parameters, the likelihood of SB compromise also increased significantly, demonstrating the predictive capability of OCT in this context.

Methods: This single-center, retrospective, and observational study evaluated 129 de novo FP lesions treated with DCB angioplasty without bailout stenting. Clinical outcomes and risk factors for loss of primary patency were analyzed using univariate and multivariate Cox proportional hazards regression models.

Article Synopsis
  • The study examines how the angle of coronary bifurcation (BA) affects incomplete stent apposition (ISA) after crossover stenting and side branch interventions in patients.
  • It compares two techniques: proximal optimization technique followed by short balloon dilation (POT-SBD) and the final kissing balloon technique (KBT), finding that major ISA is more common in the POT-SBD group.
  • The research concludes that a wider bifurcation angle increases the risk of major ISA after the POT, while a short bifurcation angle (less than 60°) is linked to lower rates of ISA when treated optimally.
