Abstract
BACKGROUND The objective of this study is to investigate the effect of preoperative diabetes on all-cause mortality and major postoperative complications among patients with continuous-flow left ventricular assist device (LVAD) by using data from a national database.Methods and Results: The 545 study patients who underwent primary HeartMateII implantation between 2013 and 2019 were divided into 2 groups according to their diabetes mellitus (DM) status; patients with DM (n=116) and patients without DM (n=429). First, the on-device survival and incidence of adverse events were evaluated. Second, after adjusting for patients' backgrounds, the change of laboratory data in the 2 groups were compared. Overall, on-device survival at 1, 2, and 3 years was almost equivalent between the 2 groups; it was 95%, 94%, and 91% in patients without DM, and 93%, 91%m and 91% in patients with DM (P=0.468) The incidence of adverse events was similar between 2 groups of patients, except for driveline exit site infection in the adjusted cohort. Cox proportional hazards regression analysis revealed younger age (HR: 0.98 (95% confidence interval (CI): 0.97-0.99, P=0.001) and presence of DM (HR: 1.83 (95% CI: 1.14-2.88), P=0.016) as significant predictors of driveline infection. Laboratory findings revealed no differences between groups throughout the periods. CONCLUSIONS The clinical results after LVAD implantation in DM patients were comparable with those in non-DM patients, except for the driveline exit site infection.

Relationship between muscle strength and rehospitalization in ventricular assist device patients. Sci Rep 2022; 12:50. [PMID: 34997047 PMCID: PMC8741760 DOI: 10.1038/s41598-021-04002-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Accepted: 12/06/2021] [Indexed: 11/09/2022] Open
Abstract
We examined the relationship between leg extensor muscle strength (LEMS) at discharge and rehospitalization within 1 year in patients with a newly implanted ventricular assist device (VAD). This study included 28 patients who had received a VAD at our institution between October 2013 and February 2019, all of whom had been discharged for 1 year. The patients were divided into two groups according to their LEMS at discharge (higher strength [group H] and lower strength [group L]), based on the median value of the 55.2 kg-force (kgf)/body weight (BW) equation. Exercise performance parameters (e.g., grip strength, 6-min walk distance, and peak VO2) and laboratory data concerning nutritional status were also collected. Nine patients (64.3%) in group L were rehospitalized within 1 year after discharge. The rehospitalization rate was significantly higher in group L than group H (p = 0.020). Compared with discharge, patients exhibited higher grip strength (56.3 vs. 48.6 kg/BW, respectively; p = 0.011), 6-min walk distances (588 vs. 470 m, respectively; p = 0.002), and peak VO2 (15.4 vs. 11.9 mL/min/kg, respectively; p < 0.001) at 1 year after discharge. However, the LEMS (57.4 vs. 58.0 kgf/BW, respectively; p = 0.798) did not increase after discharge in VAD patients who avoided rehospitalization. LEMS at discharge was associated with rehospitalization after VAD surgery; a high LEMS improves the likelihood of avoiding rehospitalization.

Risk factors of gynecological bleeding in female patients with left-ventricular assist device. J Artif Organs 2021; 25:110-116.

Abstract
Women with implantable left-ventricular assist devices (LVADs) experience gynecological bleeding (GYN-bleeding). However, a few studies have investigated female-specific problems. Therefore, this study aimed to identify the risk factors for adverse GYN-bleeding after LVAD implantation. We retrospectively analyzed 59 women (mean age: 41 ± 15 years) with long-term implantable LVAD support (≥ 6 months) at our institution between 2005 and 2018. The history of GYN-bleeding before implantation was defined as abnormal utero-ovarian bleeding, excessive menstruation, uterine fibroids, and endometrial lesions. GYN-bleeding after implantation was defined as a requirement of emergency outpatient visits and/or hospitalization, blood transfusions, hormonal therapy, and/or surgery. Additionally, risk factors for GYN-bleeding were identified using the Cox regression model. Twenty-four GYN-bleeding cases were seen in 15 patients (two times: five patients, three times: two patients, 0.18 events per patient-year). The 1- and 2-year GYN-bleeding-free rates were 84% and 73%, respectively. Twelve patients (17 events) required RBC ≥ 4 units, and five patients (7 events) required FFP ≥ 4 units. Seven patients required pseudomenopausal treatment after blood transfusion, and four patients required surgical treatment. Fifteen patients with GYN-bleeding after implantation were significantly younger than the remaining 44 patients without GYN-bleeding (34 ± 12 years vs. 43 ± 16 years, P = 0.02). Multivariable risk analysis showed a history of GYN-bleeding before implantation was a significant risk factor (hazard ratio 3.7 [1.2-10.6], P = 0.004). Patients with a history of GYN-bleeding before LVAD implantation have a high risk of developing GYN-bleeding after implantation. We should identify the high-risk population and prepare for the management of GYN-bleeding.

The incidence, risk factors, and outcomes of gastrointestinal bleeding in patients with a left ventricular assist device: a Japanese single-center cohort study. J Artif Organs 2019; 23:27-35.

Abstract
Continuous flow-left ventricular assist devices (CF-LVADs) have become a therapeutic option in the management of advanced heart failure. Several studies show that patients with CF-LVAD are at an increased risk of gastrointestinal bleeding (GIB). However, few reports have presented the characteristics of GIB in Japanese populations. We investigated the incidence, etiology, and outcome of GIB in patients with CF-LVAD. Records of adult patients who received CF-LVADs between October 2008 and January 2017 were reviewed. GIB was defined as detection of bleeding sites by any type of diagnostic imaging. 54 patients received CF-LVAD, of which eight (14%) presented with overt GIB (12 events). GIB patients are significantly older (p = 0.04) and their pre-operative inferior vena cava diameter was larger (p = 0.02). Multivariate analysis revealed that the use of Jarvik 2000 (p = 0.003) was a risk factor for GIB. In total, 85.8% of patients were free from GIB at 1 year. The most common site was the small intestine (67%). The most common cause was angiodysplasia (50%). Six patients required blood transfusion (nine events) and four underwent endoscopic clippings (five events); however, no patients needed surgeries. The incidence of GIB in our cohort was similar to the global registry data. Double balloon endoscopy is useful for diagnosis and treatment of small intestinal lesions. Future efforts to further understand the incidence of GIB in Japanese populations by multicenter data are needed.

Abstract
BACKGROUND We evaluated clinical outcomes of left ventricular assist device (LVAD) support in patients with or without severe right heart failure, in order to determine what kind of organ allocation system could help severe biventricular failure patients to be safely bridged to heart transplantation (HTx), even in Japan where the waiting time for HTx is extremely long. Methods and Results: One hundred and seventy consecutive patients who were implanted with continuous-flow LVAD at the present institution were included in this study. The patients were divided into 2 groups: 158 patients with isolated LVAD (group-LVF) and 12 patients who required long-term mechanical or inotropic right heart support (group-BVF). Post-LVAD survival in group-BVF was significantly worse than in group-LVF (P<0.0001). Given that many patients in group-BVF died between 1 and 2 years after LVAD implantation, Kaplan-Meier survival curve simulation was carried out under the condition that all the patients in group-BVF who died on LVAD support >1 year after LVAD implantation had received HTx at 365 days after LVAD implantation and survived thereafter. In this simulation, no significant difference in survival was seen between the groups (P=0.2424). CONCLUSIONS A new allocation system that allows severe right heart failure patients to receive HTx at around 1 year would enable rescue of the patients with severe right heart failure.

Abstract
The populations of Asian countries are expected to age rapidly in the near future, with a dramatic increase in the number of heart failure (HF) patients also anticipated. The need for palliative and end-of-life care for elderly patients with advanced HF is currently recognized in aging societies. However, palliative care and active treatment for HF are not mutually exclusive, and palliative care should be provided to reduce suffering occurring at any stage of symptomatic HF after the point of diagnosis. HF patients are at high risk of sudden cardiac death from the early stages of the disease onwards. The decision of whether to perform cardiopulmonary resuscitation in the event of an emergency is challenging, especially in elderly HF patients, because of the difficulty in accurately predicting the prognosis of the condition. Furthermore, advanced HF patients are often fitted with a device, and device deactivation at the end of life is a complicated process. Treatment strategies should thus be discussed by multi-disciplinary teams, including palliative experts, and should consider patient directives to address the problems discussed above. Open communication with the HF patient regarding the expected prognosis, course, and treatment options will serve to support the patient and aid in future planning.

Abstract
BACKGROUND Left ventricular assist device (LVAD) therapy is the "gold standard" alternative therapy for patients with advanced heart failure. However, LVAD therapy is still uncommon in the Asia-Pacific region. Therefore, we aimed to elucidate the clinical outcomes of patients from Japan supported with the HeartMate II (HM-II) LVAD at our institution. METHODS Ninety-two patients (mean 44.3 ± 12.1 years, 68 men, average body mass index 1.65 ± 0.28 m2; 81 with nonischemic cardiomyopathy) who underwent HM-II implantation for bridge to transplantation (n = 91) or for destination therapy in a clinical study (n = 1) at the National Cerebral and Cardiovascular Center between April 2013 and October 2017 were enrolled in this analysis. Preoperatively, most patients (n = 73, 79%) had an INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) profile of between level 2 and 4. Postoperatively, the average pump speed was 8602 ± 258 rpm and the hemodynamics were well compensated. RESULTS Adverse events consisted of 38 (41.3%) hemolysis, 30 (32.6%) major infection, 27 (29.3%) major bleeding (6 [6.5%] with gastrointestinal bleeding), and 18 (19.6%) neurologic dysfunction events. Eighteen patients underwent heart transplantation (HTx) after an average of 32.9 ± 8.9 months of VAD support, and overall survival at both 6 months and 3 years was 96.3%. CONCLUSION Clinical outcome among patients with HM-II at our institution is satisfactory for both survival and adverse events. The HM-II can provide effective hemodynamic support during the extremely long waiting period for HTx in Japan.
