Key Clinical Message: A combination of long large-bore sheath and balloon-expandable stent-graft can be effective to challenging access route in transfemoral transcatheter aortic valve replacement.

Abstract: An 88-year-old female with symptomatic severe aortic stenosis underwent transcatheter aortic valve replacement (TAVR). Multidetector computed tomography demonstrated a small aortic annulus, shaggy aorta, and significant stenosis with heavily calcified atherosclerotic lesions in the bilateral common iliac arteries (CIAs).

The number of elderly patients with acute decompensated heart failure (ADHF) is increasing, and it is often difficult to treat. This study aimed to evaluate the efficacy and safety of using tolvaptan early after hospitalization in elderly patients with ADHF and the prognosis one year after hospitalization. This study enrolled 185 patients with ADHF who were admitted for the first time.

Percutaneous coronary intervention with a drug-eluting stent was successfully performed without a side branch (SB) occlusion. In this case, a directional coronary atherectomy catheter played an important role in modifying the plaque at the proximal left anterior descending artery and in crossing a wire to the jeopardized SB.

Article Synopsis
  • * Participants were divided into "good" and "poor" recording groups based on how often they used the pedometer to track their exercise, with good recorders completing 50% or more of the daily goals.
  • * Results showed that the good recording group had significantly fewer major adverse events (MAE) after one year compared to the poor recording group, indicating that consistent home exercise is beneficial for patient outcomes post-EVT.

Despite intensive lipid-lowering interventions, patients treated with statins develop atherosclerotic cardiovascular disease (ASCVD), and these patients have an increased risk of developing recurrent cardiovascular events during follow-up. Therefore, there is a need to focus on the residual risks in patients in statin therapy to further reduce ASCVD. The aim of this study was to retrospectively investigate the 10-year trend (2011-2019) regarding changes in polyunsaturated fatty acids (PUFAs) in patients with acute coronary syndrome (ACS) in a single center.
