We aimed to examine the benefits of catheter ablation in patients with non-paroxysmal atrial fibrillation (AF) accompanied by heart failure (HF) preserved ejection fraction (HFpEF), comparison AF HF reduced (HFrEF) or no HF.From 1173 consecutive undergoing ablation, 502 were divided into three groups: history [plasma B-type natriuretic peptide (BNP) <100 pg/mL and hospitalization; n = 125], HFpEF [left ventricular (LV) EF ≥50%; 293], midrange (HFmrEF) + HFrEF (LVEF <50%; 84) groups. The...

Immune checkpoint inhibitor (ICI)-induced thyroid dysfunction is the most frequent endocrine immune-related adverse event (irAE). Thyroid hormones have various effects on cardiovascular system; however, impact of irAEs development diseases not fully understood. This retrospective study included 94 patients who received ICIs and had function troponin T levels, markers cardiac damage, measured at National Cancer Center Hospital East between January 2017 July 2022. Of patients, 36 (38%) showed...

To clarify the association of detailed angiographic findings with in-hospital outcome after primary percutaneous coronary intervention (p-PCI) for ST-elevation myocardial infarction (STEMI) in Japan.Data regarding STEMI are limited p-PCI era.Between January-2004 and December-2018, 1735 patients (mean age, 68.5 years; female, 24.6%) who presented to hospital 24-hours symptom onset underwent were evaluated using disease registries. The registry is an ongoing, retrospective, single-center...

Objective The popularity of primary percutaneous coronary intervention (p-PCI) for ST-elevation myocardial infarction (STEMI) has increased over the past decades. Despite improvements in in-hospital mortality rates, it is clinically important to investigate prognoses after discharge. However, data on mode death and prognostic factors are limited. We analyzed these a Japanese cohort modern p-PCI era.

Abstract Background Acute coronary syndrome caused by unprotected left main artery (ACS-ULMCA) occlusion has a high mortality due to the formation of plaques and rich thrombi. Although excimer laser angioplasty (ELCA) is effective in debulking ablation plaque burden thrombi, its effectiveness ACS-ULMCA remains unknown. Case summary We conducted percutaneous intervention (PCI) using ELCA for six patients with from February 2016 May 2019. This case series includes 65-year-old man who presented...

症例は60歳の男性で,心窩部痛を主訴に救急外来を受診し,腹部造影CTで膵頭部に20 mm大の乏血性腫瘤を認めた.内視鏡的逆行性胆膵管造影で,膵頭部膵管軽度狭窄に伴う尾側膵管の軽度拡張を認め,PET-CTで膵頭部腫瘤に限局性集積を認めた.超音波内視鏡下の穿刺吸引細胞診でadenocarcinomaを認め,膵癌の診断で幽門輪温存膵頭十二指腸切除術を施行した.病理組織学的検査は腺管形成が乏しく,核の大小不同・核縁不整な紡錘形の腫瘍細胞が増殖を示し,退形成性膵管癌(紡錘細胞型)と診断した.術後22日目に退院したが,術後32日目に腹痛で当院受診し,腹部造影CTで多発肝転移,腹膜播種再発を認めた.原病増悪により術後43日目に死亡した.退形成性膵管癌は膵管癌の中ではまれな組織型であり,浸潤性膵管癌の中でも予後不良とされる.退形成性膵管癌の中でも紡錘細胞型はまれであり,ここに症例を報告する.

We present a case of recurrent myocardial infarction with coronary artery ectasia that had progressive dilation. Both implanting drug-eluting stent and antithrombotic therapy warfarin plus P2Y12 inhibitor were feasible. The careful follow-up including morphologic evaluation may be needed for this specific lesion. (Level Difficulty: Intermediate.)

Abstract Background Although catheter ablation of atrial fibrillation (AF) has recently been shown to improve the cardiac function and even mortality in patients with heart failure (HF) reduced ejection fraction (HFrEF), few studies have examined outcomes AF HF preserved (HFpEF). Purpose To verify impact on status HFpEF. Methods We studied 306 who had a history an hospitalization and/or preprocedural serum BNP levels &amp;gt;100pg/ml (age, 68.9±8.2 years old; male, 66.3%; non-paroxysmal AF,...

Abstract Purpose: Clinical outcomes regarding the efficacy of excimer laser coronary angioplasty (ELCA) in real-world cases acute myocardial infarction (MI) are limited. We evaluated impact ELCA on salvage and left ventricular (LV) systolic/diastolic function patients with ST-segment elevation MI (STEMI) compared manual aspiration thrombectomy using nuclear scintigraphy. Methods: enrolled 143 consecutive STEMI treated (63 patients) or (80 between September 2016 December 2020 a single-center...

Background: The atrial defibrillation threshold (ADFT) for internal cardioversion is theoretically related to the critical mass sustaining fibrillation (AF). Objective: This study aimed investigate association of ADFT with outcome catheter ablation non-paroxysmal AF (non-PAF). Methods: We included 368 consecutive patients who underwent first-time non-PAF. Based on degree recorded by before pulmonary vein isolation, we divided into low (<20 J) and high (≥20 groups analyzed between...
