Abstract

Iliac artery rupture during endovascular therapy (EVT) is a life-threatening complication requiring prompt diagnosis and treatment. However, delayed rupture of the iliac artery after EVT is rare, and its predictive value remains unknown. Herein, we present the case of a 75-year-old woman who developed delayed iliac artery rupture 12 h after balloon angioplasty and placement of a self-expandable stent in the left iliac artery. Hemostasis was achieved with a covered stent graft. However, the patient died of hemorrhagic shock. From the review of previous case reports and the pathological findings of the current case, increased radial force due to overlapping stent and kinking of the iliac artery may be associated with delayed iliac artery rupture. LEARNING OBJECTIVE: Delayed iliac artery rupture after endovascular therapy is rare but with a poor prognosis. Hemostasis can be achieved using a covered stent; however, the outcome could be fatal. Based on pathological findings and previous case reports, increased radial force at the stent site and kinking of the iliac artery may be associated with delayed iliac artery rupture. Self-expandable stent probably should not be overlapped at the site where kinking is likely to occur, even if long stenting is needed.

32. Sodium-Glucose Cotransporter-2 Inhibitors in Heart Failure with Malnutrition, Frailty, Sarcopenia, or Cachexia.

Abstract

(1) Background: In patients with heart failure (HF) and impaired nutritional status or decreased muscle mass, sodium-glucose cotransporter-2 inhibitors (SGLT2is) may worsen these conditions and result in poor prognosis, especially worsening of frailty. We aimed to investigate the relationship between SGLT2is and clinical outcomes, including frailty-related events, in patients with HF and malnutrition, frailty, sarcopenia, or cachexia. (2) Methods: In this retrospective observational cohort study, a global federated health research network provided data on patients with HF and malnutrition, frailty, sarcopenia, or cachexia from January 2016 to December 2021. We investigated the incidence of the composite endpoint of death or frailty-related events within one year. (3) Results: Among 214,778 patients included in the analysis, 4715 were treated with SGLT2is. After propensity score matching, 4697 patients in the SGLT2is group were matched with 4697 patients in the non-SGLT2is groups. The incidence of the composite endpoint, mortality, and frailty-related events was lower in the SGLT2is group than in the non-SGLT2is group (composite endpoint, 65.6% versus 77.6%, p < 0.001; mortality, 17.4% vs. 35.5%, p < 0.001; frailty-related events, 59.4% vs. 64.3%, p < 0.001). (4) Conclusions: Patients with HF and malnutrition, frailty, sarcopenia, or cachexia had a high incidence of death and frailty-related events. SGLT2is were associated with a lower incidence of these events. [ABSTRACT FROM AUTHOR]

33. Pacemaker implantation in a patient with isolated persistent left superior vena cava using a delivery catheter: a case report.

Abstract

Background Persistent left superior vena cava (PLSVC) with absent right superior vena cava, also termed 'isolated PLSVC', is extremely rare. Permanent pacemaker implantation in patients with isolated PLSVC is often difficult by the usual subclavian approach due to the unique anatomy. With the advent of delivery catheters in recent years, implantation using the same system has been reported. Case summary A 47-year-old woman with symptomatic sick sinus syndrome was admitted to our institution for permanent pacemaker implantation. Preprocedural cardiac multidetector computed tomography (MDCT) showed isolated PLSVC. We performed pacemaker implantation successfully via the left subclavian approach, using the C315 delivery catheter system. The leads were stable on chest radiography, and the sensing and capture thresholds were unchanged. After the procedure, we integrated the delivery catheter images with cardiac MDCT using Ziostation, and they were well matched with the fluoroscopic images. At the 1-month follow-up, the patient was free of heart failure symptoms and had decreased levels of N-terminal prohormone of brain natriuretic peptide. Discussion The C315 delivery catheter system was considered an option for permanent pacemaker implantation in patients with isolated PLSVC. When performing permanent pacemaker implantation in patients with unusual venous anatomy, integrating the delivery catheter images with cardiac MDCT allows for appropriate preoperative catheter selection.

Abstract

Aims: We aimed to investigate the characteristics and prognosis of patients with heart failure (HF) with supra‐normal ejection fraction (HFsnEF) compared to HF with normal ejection fraction (HFnEF). Methods and results: Among 11 573 patients enrolled in the nationwide registry of hospitalized patients with HF in Japan, 1943 patients (16.8%) were classified as HFsnEF (left ventricular ejection fraction [LVEF] >65%), 3277 (28.3%) as HFnEF (50% ≤ LVEF ≤65%), 2024 (17.5%) as HF with mildly reduced ejection fraction (40% ≤ LVEF <50%) and 4329 (37.4%) as HF with reduced ejection fraction (LVEF <40%). Patients with HFsnEF were older, more likely to be women, had lower natriuretic peptide values, and had smaller left ventricles than those with HFnEF. The primary endpoint, the composite of cardiovascular death or HF readmission, did not differ between HFsnEF (802/1943, 41.3%) and HFnEF (1413/3277, 43.1%) during a median follow‐up period of 870 days (hazard ratio [HR] 0.96, 95% confidence interval 0.88–1.05, p = 0.346). The incidence of secondary outcomes, including all‐cause, cardiovascular, and non‐cardiovascular deaths and HF readmission, did not differ between HFsnEF and HFnEF. In the multivariable Cox regression analysis, HFsnEF compared to HFnEF was associated with a lower adjusted HR for HF readmission but not with the primary and other secondary endpoints. HFsnEF was associated with a higher HR for the composite endpoint and all‐cause death in women, and a higher HR for all‐cause death in patients with renal dysfunction. Conclusions: Heart failure with supra‐normal ejection fraction is a common and distinctive phenotype, and has different characteristics and prognoses from HFnEF. [ABSTRACT FROM AUTHOR]
