    <p>The 87<sup>th</sup>Annual Meeting of the Japanese Circulation Society (JCS2023) was held in March 2023 in Fukuoka, Japan, marking the first in-person gathering after the COVID-19 pandemic. With the theme of “New Challenge With Next Generation” the conference emphasized the development of future cardiovascular leaders and technologies such as artificial intelligence (AI). Notable sessions included the Mikamo Lecture on heart failure and the Mashimo Lecture on AI in medicine. Various hands-on sessions and participatory events were well received, promoting learning and networking. Post-event surveys showed high satisfaction among participants, with positive feedback on face-to-face interactions and the overall experience. JCS2023, attended by 17,852 participants, concluded successfully, marking a significant milestone in post-pandemic meetings, and advancing cardiovascular medicine.</p>

    Background: Advances in catheter ablation (CA) for atrial fibrillation (AF) have improved the prognosis of patients with heart failure (HF) and AF. However, its optimal timing remains to be fully elucidated. Objectives: The aim of this study was to investigate the prognostic impact of early CA in patients with HF and AF hospitalized for worsening HF. Methods: From JROADHF (Japanese Registry of Acute Decompensated Heart Failure) (n = 13,238), patients with HF and AF who underwent CA within 90 days after admission for HF (early CA; n = 103) and those who did not (control; n = 2,683) were identified. Mortality was compared between these groups in the crude cohort, as well as in the propensity-matched cohort (n = 83 in each group). Results: In the crude cohort, all-cause mortality was significantly lower in the early CA group than in the control group (log-rank P < 0.001; HR: 0.38; 95% CI: 0.24-0.60). In the matched cohort, all-cause mortality was likewise significantly lower in the early CA group (log-rank P = 0.014; HR: 0.47; 95% CI: 0.25-0.88). Cardiovascular death and HF mortality were significantly lower in both cohorts (crude: Gray’ test: P < 0.001 and P = 0.005; subdistribution HR: 0.28 [95% CI: 0.13-0.63] and HR: 0.31 [95% CI: 0.13-0.75]; matched: Gray's test: P = 0.006 and P = 0.017; subdistribution HR: 0.24 [95% CI: 0.08-0.70] and HR: 0.28 [95% CI: 0.09-0.84], respectively). Conclusions: In a nationwide representative real-world cohort, CA for AF within 90 days after admission for HF was associated with improved long-term outcomes, including cardiovascular and HF death in patients with HF and AF.

    Background: Past studies have shown the sex-related difference in the efficacy of cardiac resynchronization therapy (CRT). However, the data for cardiac sarcoidosis (CS) are limited. Objective: The purpose of this study was to assess the sex-related prognostic differences in CS patients with CRT. Methods: This multicenter CS survey included 430 patients (295 females) who met the diagnostic criteria for CS. Patients were divided into those treated with primary CRT or upgraded CRT from the pacemaker (CRT group; n = 73) and others (control group; n = 357). Sex differences in the incidence of all-cause death, heart failure (HF) death including heart transplantation, ventricular arrhythmia events (VAEs) (sudden death, appropriate device therapy), cardiac adverse events (CAEs) (HF death, VAEs), changes in serum brain natriuretic peptide (BNP) levels, and left ventricular ejection fraction (LVEF) over the follow-up period were analyzed. Results: During median follow-up of 5.2 years, males, but not females, in the CRT group had significantly worse all-cause mortality than patients in the control group (P <.001). In the CRT group, there was no significant sex-related difference in the incidence of HF death; however, females had significantly better VAE- and CAE-free survival than males (P = .033 and P = .008, respectively). Multivariate analysis of the CRT group showed that female sex (hazard ratio 0.37; 95% confidence interval 0.15–0.89; P = .02 and P = .6) independently predicted freedom from CAEs. During follow-up, BNP levels were significantly improved in all groups. LVEF was maintained in females with CRT. Conclusions: In CS patients with CRT, HF death-free survival was similar between sexes. However, females exhibited better VAE- and CAE-free survival than males.

    Background Pulmonary vein isolation (PVI) is an established ablation procedure for atrial fibrillation (AF), however, PVI alone is insufficient to suppress AF recurrence. Non-pulmonary vein (non-PV) trigger ablation is one of the promising strategies beyond PVI and has been shown to be effective in refractory/persistent AF cases. To make non-PV trigger ablation more standardized, it is essential to develop a simple method to localize the origin of non-PV triggers. Methods We retrospectively analyzed 37 non-PV triggers in 751 ablation sessions for symptomatic AF from January 2017 to December 2020. Regarding non-PV triggers, intra-atrial activation interval from the earliest in right atrium (RA) to proximal coronary sinus (CS) (RA-CSp) and that from the earliest in RA to distal CS (RA-CSd) obtained by a basically-positioned duodecapolar RA-CS catheter were compared among 3 originating non-PV areas [RA, atrial septum (SEP) and left atrium (LA)]. Results RA-CSp of RA non-PV trigger (56.4 ± 23.4 ms) was significantly longer than that of SEP non-PV (14.8 ± 25.6 ms, p = 0.019) and LA non-PV (-24.9 ± 27.9 ms, p = 0.0004). RA-CSd of RA non-PV (75.9 ± 32.1 ms) was significantly longer than that of SEP non-PV (34.2 ± 32.6 ms, p = 0.040) and LA non-PV (-13.3 ± 41.2 ms, p = 0.0008). RA-CSp and RA-CSd of SEP non-PV were significantly longer than those of LA non-PV (p = 0.022 and p = 0.016, respectively). Sensitivity and specificity of an algorithm to differentiate the area of non-PV trigger using RA-CSp (cut-off value: 50 ms) and RA-CSd (cut-off value: 0 ms) were 88% and 97% for RA non-PV, 81% and 73% for SEP non-PV, 65% and 95% for LA non-PV, respectively. Conclusions The analysis of intra-atrial activation sequences was useful to differentiate non-PV trigger areas. A simple algorithm to localize the area of non-PV trigger would be helpful to identify non-PV trigger sites in AF ablation.
