Factors Predicting the Maintenance of Sinus Rhythm by Pulmonary Vein Isolation Alone in Persistent Atrial Fibrillation Open
Persistent atrial fibrillation (PerAF) still exhibits less favorable outcomes post-ablation and the efficacy of linear or substrate ablation in addition to pulmonary vein isolation (PVI) remains controversial. The relationship between P-wa…

Sex Differences in Impacts of Alcohol Consumption on Prevalent Atrial Fibrillation Open
Background High levels of alcohol consumption are a well‐established risk factor for atrial fibrillation (AF). Although women currently tend to regulate alcohol intake more strictly than men, it remains unclear whether alcohol consumption …

Coronary Rupture Right After Intravascular Lithotripsy for Severely Calcified Coronary Lesion With C-CAT Sign Open
The C-CAT sign has been reported to be a potential predictor of CAR in patients with severely calcified lesions. Downsizing the IVL balloon may reduce the risk of CAR when the C-CAT sign is present on intravascular ultrasound.

Predictors of Stent Underexpansion for Severely Calcified Lesions After Debulking Open
The role of calcium parameters in predicting SUE in severely calcified lesions after suitable debulking using RA or OA is weak; however, maximum lipid arc and TCFA are important predictors of SUE.

Randomized trial to assess worsening renal function by adding dapagliflozin for acute decompensated heart failure Open
Aims Dapagliflozin (DAPA), a sodium‐glucose co‐transporter 2 inhibitor, has been shown to reduce cardiovascular mortality among patients with chronic heart failure. We aimed to evaluate the impact on a worsening renal function (WRF) by add…

Impact of combining ablation index‐guided and very high‐power short‐duration ablation at posterior wall adjacent to esophagus during perioperative period on procedural factors Open
Introduction The impact of combining ablation index (AI)‐guided and very high‐power short‐duration (vHPSD) ablation on procedural factors at the posterior wall near the esophagus is unclear. Methods Atrial fibrillation patients who underwe…

Impact of Pre-reperfusion Left Ventricle Unloading on ST-segment-elevation Myocardial Infarction According to the Onset-to-Unloading Time Open
Background Impella in the left ventricle (LV) with delaying reperfusion reduces the infarction size in animal models. However, the onset-to-unloading time in real-world practice can frequently be longer than that in animal experiments. It …

Prognostic Comparison of Octogenarian vs. Non-Octogenarian With Acute Decompensated Heart Failure ― AURORA Study ― Open
The proportion of HFpEF among in-hospital deaths of octogenarians with ADHF was high as compared with non-octogenarians. When octogenarians with ADHF have severe hypoalbuminemia and antiplatelet agents, early nutritional and medical interv…

Membranous tracheal wall reconstruction using a latissimus dorsi flap for adenoid cystic carcinoma Open
61歳男性．胸部CTで気管背側に接する腫瘍を認め，経食道的に生検を行い腺様囊胞癌と診断．転移は認めず手術を行った．左側臥位，右後側方切開にて有茎広背筋弁を採取し，第4肋間で開胸．気管膜様部に限局する6×4 cmの腫瘍で，10気管輪に及ぶため端端吻合での再建は困難であり，気管管状切除は断念した．腫瘍基部の辺縁で気管膜様部のみを切除し，欠損部は広背筋弁を縫着し再建した．術直後に喉頭浮腫を認めたが，重大な合併症なく経過良好だった．顕微鏡的遺残腫瘍を認めたが，術後放射線療法を行い，…
