Purpose: Information on the relationship between frailty and the outcome of endovascular therapy (EVT) in elderly patients with lower extremity peripheral artery disease (PAD) is scarce. This study aimed to reveal the impact of frailty on the prognosis of super-elderly patients who underwent EVT. Materials and Methods: From August 2015 to August 2016, 335 consecutive patients who underwent EVT were enrolled in the I-PAD registry from 7 institutes in Nagano prefecture. Among them, we categorized 323 patients into 4 groups according to age and the presence or absence of frailty as follows: elderly with frailty (age ≥ 75, Clinical Frailty Scale [CFS] ≥ 5), elderly without frailty (age ≥ 75, CFS ≤ 4), young with frailty (age < 75, CFS ≥ 5), and young without frailty (age < 75, CFS ≤ 4); we analyzed them accordingly. The primary endpoints were major adverse cardiovascular and limb events (MACLE), defined as a composite of cardiovascular death, myocardial infarction, stroke, admission for heart failure, major amputation, and revascularization. The secondary endpoint was cardiovascular death. Results: The median follow-up period was 2.7 years. In the elderly with frailty, elderly without frailty, young with frailty, and young without frailty groups, the freedom rates from MACLE were 34.9%, 55.7%, 35.4%, and 63.0%, respectively (p<0.001) and from all-cause death were 43.5%, 73.4%, 50.7%, and 90.9%, respectively (p<0.001). The freedom rates from MACLE were significantly higher among elderly patients with frailty than among young patients without frailty (55.7% vs 35.4%, p=0.01). In multivariate analysis, frailty was independently associated with MACLE incidence. Conclusion: Frailty as defined by CFS might be a predictor of MACLE incidence in patients with PAD who underwent EVT. By considering treatment indications for patients with PAD by focusing on frailty rather than age, we may examine whether EVT policies are appropriate and manage patient and caregiver expectations for potential improvement in functional outcomes. Further studies are expected to investigate whether changes in frailty after EVT change prognosis. [ABSTRACT FROM AUTHOR]

We investigated the prognostic effects of hyperuricemia and high or low body mass index (BMI) in peripheral artery disease (PAD) after endovascular therapy (EVT). Between July 2015–2016, 357 consecutive patients with PAD who underwent EVT were enrolled. Patients were divided into 2 groups: BMI < 25 kg/m2 (low BMI) and ≥ 25 kg/m2 (high BMI); they were also divided into 2 more groups based on the presence/absence of hyperuricemia. The primary and secondary endpoints were major adverse cardiovascular and limb events (MACLE), and all-cause death at 3 years post-EVT. Patients with hyperuricemia had significantly lower freedom from MACLE than patients without hyperuricemia at 3 years (57.0 vs 71.9%, p =.0068). The overall survival of patients with hyperuricemia was significantly lower than that of patients without hyperuricemia (63.9 vs 81.7%, p =.0012). Patients with hyperuricemia who had low BMI experienced significantly lower freedom from MACLE than those without hyperuricemia who had low BMI (48.2 vs 69.9%, p =.002). The overall survival of patients with hyperuricemia who had low BMI was significantly lower than that of patients without hyperuricemia who had low BMI (55.2 vs 77.1%, p =.003). Patients with hyperuricemia had significantly more MACLE and a lower survival at 3 years than patients without hyperuricemia, even if they had a low BMI. [ABSTRACT FROM AUTHOR]

Background: Optimal lesion preparation for coronary lesions has been reappraised in the interventional community, given the increasing use of drug-coated balloons for de novo lesions; however, whether multiple ballooning could achieve more favorable angiographic results compared with single ballooning remains unknown. We aimed to investigate the incremental effect of multiple ballooning on de novo coronary lesions over single ballooning as assessed by optical coherence tomography (OCT) and intravascular ultrasound (IVUS) among patients undergoing percutaneous coronary intervention (PCI)., Methods: Patients with chronic coronary syndrome (CCS) undergoing PCI were enrolled. Ballooning before stent implantation was repeatedly performed for three times using the same semi-compliant balloon. OCT and IVUS were performed after each balloon dilatation. Primary outcome measure was the difference in the mean lumen area between post-1st ballooning (1B) and post-3rd ballooning (3B) as assessed by OCT., Results: A total of 32 lesions in 30 patients undergoing PCI between May 2021 and August 2022 were analyzed. Major plaque types of the lesions were fibrous (68.8%) and lipid (28.1%). Mean lumen area by OCT was significantly increased from 1B to 3B (5.9 ± 2.9 mm 2 vs. 6.0 ± 2.9 mm 2 , difference: 0.2 ± 0.4 mm 2 , p = 0.040). There were significant increases from 1B to 3B in minimum lumen area by OCT (3.1 ± 1.5 mm 2 vs. 3.6 ± 1.7 mm 2 , difference: 0.5 ± 0.6 mm 2 , p < 0.001) and mean dissection angle by OCT (65.6 ± 24.9° vs. 95.2 ± 34.0°, difference: 29.6 ± 25.5°, p < 0.001). Additionally, mean plaque area by IVUS was significantly decreased (8.0 ± 4.2 mm 2 vs. 7.8 ± 4.1 mm 2 , difference: -0.2 ± 0.2 mm 2 , p < 0.001)., Conclusions: Among CCS patients with mainly non-calcified lesions, multiple ballooning significantly increased the lumen area and dissection angle compared with single ballooning., (© 2024 The Author(s).

Cardiac resynchronization therapy (CRT) is a standard treatment for patients with severe congestive heart failure. However, one-third of patients receiving CRT are non-responders. Conduction system pacing (CSP), including His-bundle pacing (HBP) and left bundle branch area pacing (LBBAP), has become an alternative to CRT therapy. Furthermore, CRT therapy with CSP has shown to be more effective than CRT alone. When an implantable cardiac defibrillator or CRT-defibrillator is implanted with CSP, the problem of which port the HBP lead and LBBAP lead should be connected to arises. We report 2 cases of upgrading to CRT with CSP by utilizing the atrial ports for HBP and LBBAP leads. The procedure is a simple, reasonable, and effective therapy for end-stage heart failure.
