    Abstract Objectives: Although risk factors for unsuccessful Maze procedure have been demonstrated, an appropriate patient selection is still controversial. In our institute, Maze procedure is indicated for those whom normal sinus rhythm (NSR) was reestablished by intraoperative direct cardioversion (DC) after ventricular unloading by total cardiopulmonary bypass. The purpose of this study was to evaluate the effectiveness of our indication criteria for Maze procedure in patients with mitral valve disease.
    Methods: Between October 2012 and October 2021, MAZE was indicated in 55 patients in whom normal sinus rhythm (NSR) was reestablished by intraoperative direct current cardioversion (DC). Three endpoints and predictors were examined: disappearance of atrial fibrillation (AF), NSR, and A-wave detection.
    Results: Restoration of NSR by intraoperative DC was confirmed in 43 patients, and these patients underwent MAZE. AF disappeared in 39 patients (90.7%), and F-wave ≥ 0.1 mV was a significant predictive factor (odds ratio (OR) 20.99, 95% CI 1.22-1079.06). NSR was reestablished in 36 patients (83.7%), and F-wave ≥ 0.1 mV (odds ratio 15.62, 95% CI 1.62-359.86) + AF history ≤ 3 years (OR 8.30, 95% CI 1.09-177.04) were significant predictors. A-wave detection was confirmed in 26 patients (60.5%), and left atrial diameter ≤ 55 mm was a significant predictor (OR 5.22, 95% CI 1.28-24.79).
    Conclusions: Intraoperative DC after ventricular unloading resulted effective patient selection for concomitant Maze procedure. F-wave and AF history were predictive factor of electrical restoration of AF, and left atrial diameter was predictive factor of restoration of atrial function.

    Abstract Purpose: We studied the association between operative timing and the feasibility of mitral valve (MV) repair in active infective endocarditis (IE).
    Methods: Forty-nine active IE patients who underwent MV operation were classified according to operative timing: within 48 hours (Term I: n = 7), between 3 and 14 days (Term II: n = 22), and ≥15 days (Term III: n = 20). Patient profiles, operative outcomes, and feasibility of MV repair were evaluated. Complexity score and severity score were used to define the feasibility of MV repair depending on the extent of infected lesion and technical difficulties.
    Results: There were no differences in basic profile in the three groups. Rate of major complications was higher in Term I (86%) than II (41%, p = 0.031) and III (25%, p = 0.005). In-hospital mortality was also higher in Term I (43%) than II (9%, p = 0.039) and III (5%, p = 0.015). The three groups did not differ by feasibility of MV repair calculated by the two-score system or by frequency of MV repair (I: 57%, II: 59%, and III: 55%).
    Conclusions: Morbidity and mortality were high in urgent cases. Feasibility of MV repair is associated with the extent of infected lesion and technical difficulties, and not with operative timing.

    Abstract Parkinson's disease (PD) is a neurodegenerative disease manifesting with motor and non-motor symptoms. Current treatment mainly relies on medication as a symptomatic therapy modulating neurotransmitters. Dopamine replacement therapy has been established, and levodopa is the gold standard for treatment of PD. However, the emergence of motor complications, such as a wearing-off phenomenon, is a clinical problem. Both primary symptoms and motor complications have been targets for the development of treatments for PD. Recent progression in the management of motor complications is supported by newly developed agents and advances in device and formulation technology to deliver drugs continuously. Elucidation of the pathophysiology of PD and the development of disease-modifying therapy that affects the underlying fundamental pathophysiology of the disease are also progressing. In this review, we introduce current knowledge on developments concerning medications for patients with PD.

    Abstract The right ventricular (RV) impairment can predict clinical adverse events in patients following transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS). Limited reports have compared impact of the left ventricular (LV) and RV disorders. This retrospective study evaluated two-year major adverse cardiac and cerebrovascular events (MACCE) in patients following TAVR for severe AS. RV sphericity index was calculated as the ratio between RV mid-ventricular and longitudinal diameters during the end-diastolic phase. Of 239 patients, 2-year MACCE were observed in 34 (14%). LV ejection fraction was 58 ± 11%. Tricuspid annular plane systolic excursion (TAPSE) and RV sphericity index were 20 ± 3 mm and 0.36 (0.31-0.39). Although the univariate Cox regression analysis demonstrated that both LV and RV parameters predicted the outcomes, LV parameters no longer predicted them after adjustment. Lower TAPSE (adjusted hazard ratio per 1 mm, 0.84; 95% confidence interval, 0.75-0.93) and higher RV sphericity index (adjusted hazard ratio per 0.1, 1.94; 95% confidence interval, 1.17-3.22) were adverse clinical predictors. In conclusion, the RV structural and functional disorders predict two-year MACCE, whereas the LV parameters do not. Impact of LV impairment can be attenuated after development of RV disorders.

    Abstract Background: Individuals with Parkinson's disease (PD) may present with rapid eye movement sleep behavior disorder (RBD). We therefore investigated the association between RBD and quality of life (QOL) in people with PD.
    Methods: Individuals with PD and a Mini-Mental State Examination score ≥ 24 were divided into two groups using the RBD screening questionnaire (RBDSQ): those with an RBDSQ score ≥ 5 were assigned to the "probable RBD" (pRBD) group, and those with a score < 5 to the "non-pRBD" group. Participants were then evaluated for motor symptoms (Movement Disorder Society-Unified Parkinson's Disease Rating Scale part III and modified Hoehn and Yahr Scale), cognitive functions (Montreal Cognitive Assessment and Frontal Assessment Battery [FAB]), anhedonia (Snaith-Hamilton Pleasure Scale), and QOL (Parkinson's Disease Questionnaire [PDQ]-39 total and subscores for mobility, activities of daily living, emotional well-being, stigma, social support, cognition, communication, and bodily discomfort). Each measure was compared between the two groups (Mann-Whitney U test/χ
    Results: Ninety-three individuals with PD were recruited (mean ± standard deviation age, 67.0 ± 10.6 years). The pRBD group exhibited a longer disease duration (P = 0.006), worse FAB (P = 0.015) and PDQ-39 total (P = 0.032) scores. RBDSQ scores correlated with higher scores in the PDQ-39 stigma domain (B = 2.44, P = 0.033).
    Conclusion: RBD is associated with worse QOL and stigma in people with PD. The RBDSQ is a useful tool for the prediction of such disturbances in QOL.

    Abstract Objective: The midterm results of endovascular abdominal aortic aneurysm repair (EVAR) with aortic side branch coil embolization during EVAR was evaluated.
    Methods: Our center began coil embolization for all patent inferior mesenteric artery (IMA) and lumbar artery (LA) with an inner diameter more than 2.0 mm during EVAR since June 2015. When four or more LA were patent, coil embolization for LA with inner diameter 2.0 mm or less was done. EVAR without aortic side branches coil embolization was performed for 59 patients prior to June 2015 (control group) and 79 patients underwent EVAR with coil embolization during EVAR (coil group). The success rate of coil embolization for IMA and LA was evaluated in coil group. The frequency of type 2 endoleak (T2EL), freedom from aneurysm sac expansion (5 mm or more) rate and the rate of the aneurysm sac shrinkage (10 mm or more) were compared between the coil and control groups. Additionally, multiple logistic regression analysis for all patients was conducted to analyze whether IMA patency and the number of patent lumbar artery at the end of EVAR were the risk factors of the aneurysm sac expansion of 5 mm or more.
    Results: The success rate of IMA coil embolization was 96.4% and that of LA was 74.5%. Compared to the control group, the frequency of T2EL was significantly lower in coil group at 7 days (1.3% vs. 60.4%, P <0.0001) and at 6 months (2.1% vs 38.2%, P <0.0001) after EVAR. The freedom from aneurysm sac expansion rate was significantly better in the coil group at 5 years (100% in coil group and 65.2% in control group, P = 0.002). The rate of aneurysm sac shrinkage was significantly better in coil group (15.5% vs. 2.0% at 1 year, 42.8% vs. 6.3% at 2 years and 53.4% vs. 17.8% at 3 years, p = 0.0007). The risk of aneurysm sac expansion of 5 mm or more was estimated to be 11 times greater when the IMA was patent, and 4.9 times greater when 3 or more LAs were patent at the end of EVAR.
    Conclusion: When IMA was occluded and the number of patent LA became 2 or less by aortic side branch coil embolization during EVAR, favorable mid-term results were safely obtained and good long-term result could be expected with EVAR.

    Abstract Background: Myotonic dystrophy type 1 (DM1) is an autosomal dominant genetic disorder that affects multiple organs, including the muscle and eye, caused by a CTG triplet expansion of the 3' untranslated region (UTR) of the DMPK gene. Cataracts and retinal degeneration are major eye complications in patients with DM1. We reported the case of a Japanese patient with DM1 who exhibited submacular hemorrhage unilaterally, rarely complicating DM1.
    Case report: A 56-year-old woman presented with loss of visual acuity in the left eye (LE). The patient was diagnosed with DM1, who carried expanded CTG repeats (1100) of the 3' UTR of DMPK. Her corrected visual acuities were 20/100 and 20/2000 in the right eye (RE) and LE, respectively. Cataracts were observed in both eyes. Fundoscopy and angiography revealed submacular hemorrhage in the LE due to polypoidal choroidal vasculopathy (PCV, also known as aneurysmal type 1 neovascularization). The patient underwent intravitreal injections of an anti-vascular endothelial growth factor drug and sulfur hexafluoride gas in the LE. Full-field electroretinography was performed, showing that the rod and standard-flash responses were reduced to 50% and below 10% in the RE and LE, whereas the cone and 30-Hz flicker responses were reduced to 40-50% and 15-20% in the RE and LE, respectively, compared with the controls. Multifocal electroretinography revealed that the overall responses were extinguished in the LE and considerably attenuated in the RE.
    Conclusions: This is the first patient with DM1 complicated with PCV. Widespread retinal dysfunction may be associated with expanded CTG repeats, which is significantly longer than the mean repeat number of patients with DM1.

    Abstract Background: Accumulating evidence suggests that peripheral inflammation is associated with the pathogenesis of Parkinson's disease (PD). We examined peripheral immune profiles and their association with clinical characteristics in patients with DLB and compared these with values in patients with PD.
    Methods: We analyzed peripheral blood from 93 participants (drug-naïve DLB, 31; drug-naïve PD, 31; controls, 31). Absolute leukocyte counts, absolute counts of leukocyte subpopulations, and peripheral blood inflammatory indices such as neutrophil-to-lymphocyte ratio were examined. Associations with clinical characteristics, cardiac sympathetic denervation, and striatal
    Results: Patients with DLB had lower absolute lymphocyte and basophil counts than did age-matched controls (both; p < 0.005). Higher basophil counts were marginally associated with higher global cognition (p = 0.054) and were significantly associated with milder motor severity (p = 0.020) and higher striatal
    Conclusions: As in patients with PD, the peripheral immune profile is altered in patients with DLB. Some peripheral immune cell counts and inflammatory indices reflect the degree of disease progression. These findings may deepen our knowledge on the role of peripheral inflammation in the pathogenesis of DLB.
