Abstract
Advance care planning (ACP) is essential in managing serious and chronic illnesses to ensure that patients receive care aligned with their personal values, goals, and preferences. This review focuses on integrating ACP in the treatment of patients receiving implantable left ventricular assist devices (VADs). The heart failure palliative care team developed a unique advance directive form and pamphlet to facilitate ACP discussions, emphasizing not only medical treatment preferences but also patients' values and life goals.The study highlights the distinction between bridge to transplantation (BTT) and destination therapy (DT) in VAD patients, with different goals and considerations for ACP. The use of decision aids developed especially for DT candidates as a communication tool helps in sharing patients' wishes and facilitates shared decision-making, particularly in the complex decisions surrounding DT therapy.Challenges in implementing ACP, such as time constraints due to urgent medical conditions, difficulties in patient communication, and the recent COVID-19 pandemic, are addressed. The need for a comprehensive healthcare system capable of supporting patients' ACP wishes, especially in the community setting, is also pointed out.Future directions include not only developing materials to ease ACP discussions and ensuring that ACP content is shared among healthcare providers to foster collaborative and detailed planning, but also a call for widespread adoption of ACP in Japan.This is a translation of a paper written in Japanese Journal of Artificial Organs (Vol. 52, No. 1, pp. 89-92) with additions and corrections.

Abstract
BACKGROUND For patients with nonischemic dilated cardiomyopathy (NIDCM), the indications for and results of mitral surgery remain controversial. We reviewed a strategy of mitral repair and replacement for clinically relevant secondary mitral regurgitation (MR) in patients with NIDCM. METHODS We retrospectively reviewed 65 patients with advanced NIDCM (LVEF < 40%) who underwent mitral surgery. Of them, 47 (72%) underwent mitral annuloplasty and 18 (28%) replacement for secondary MR. The primary endpoint was postoperative reduction in indexed LV end-systolic volume (LVESVI). RESULTS At baseline, there was no intergroup difference in LVESVI (123 ± 47 vs. 147 ± 37 ml/m2, P = 0.055), LVEF (27 ± 8% vs. 25 ± 6%, P = 0.41), incidence of severe MR (57% (27/47) vs. 72% (13/18), P = 0.40), or EuroSCORE II score (6.2% vs. 7.6%, P = 0.90). At 6 months, the annuloplasty group reduced LVESVI to a greater degree than the replacement group (P < 0.001), yielding significantly smaller postoperative LVESVI (96 ± 59 vs. 154 ± 61 ml/m2, P < 0.001) and better LVEF (P < 0.001). The rates of moderate/severe recurrent MR were 17% (8/47) and 0%, respectively. Multivariable analysis demonstrated that mitral annuloplasty (OR 6.10, 95% CI 1.14-32.8, P = 0.035) was significantly associated with postoperative LV reverse remodeling. Cumulative survival was not different between the groups (P = 0.26). CONCLUSIONS In patients with NIDCM, mitral annuloplasty reduced LV volume to a greater degree than did mitral replacement. These findings may assist with surgical options for secondary MR associated with NIDCM.

Abstract
Patients with diffuse frontal gliomas often present with post-operative apathy after tumour removal. However, the association between apathy and tumour removal of gliomas from the frontal lobe remains unknown. This study aimed to investigate the factors influencing post-operative apathy after tumour removal in patients with diffuse frontal gliomas. We compared the demographics and clinical characteristics of patients with and without post-operative apathy in a cohort of 54 patients who underwent awake brain mapping for frontal gliomas. The frequency of clinical parameters such as left-sided involvement, high-grade tumour types (WHO grades III, IV), main tumour location in the anterior cingulate gyrus (ACC) and/or dorsolateral prefrontal cortex (DLPFC) and orbitofrontal cortex (OFC) was significantly greater in the apathetic group compared to the non-apathetic group. The apathetic group scored significantly lower on neuropsychological assessments such as the Letter Fluency Test among the Word Fluency Tests than the non-pathetic group (p = .000). Moreover, the scores of Parts 3, and 3-1 of the Stroop test were significantly lower in the apathetic group than those in the non-apathetic group (p = .023, .027, respectively). Multivariate model analysis revealed that the appearance of post-operative apathy was significantly related to side of the of lesion [left vs. right, hazard ratio (HR) = 8.00, 95% confidence interval (CI) = 1.36-46.96, p = .021], location of the main tumour in the frontal lobe (ACC/DLPFC/OFC vs. others, HR = 7.99, 95% CI = 2.16-29.59, p = .002), and the Letter Fluency Test (HR = .37, 95% CI = .15-.90, p = .028). Post-operative apathy is significantly associated with ACC and/or DLPFC and OFC in the left hemisphere of diffuse frontal gliomas. Apathy in frontal gliomas is correlated with a decline in the Letter Fluency Test scores. Therefore, this instrument is a potential predictor of post-operative apathy in patients with diffuse frontal gliomas undergoing awake brain mapping.

Abstract
An 82-year-old man who underwent transcatheter aortic valve replacement (TAVR) using a 34-mm Evolut PRO (Medtronic, Minneapolis, MN, USA) for severe aortic stenosis 21 months previously presented with fever. Transesophageal echocardiography showed thickening of the valve leaflets of the transcatheter heart valve and movable structures such as verrucae on the upper edge of the Evolut PRO stent. Contrast-enhanced cardiac computed tomography showed a 72-mm saccular pseudoaneurysm on the dorsal aspect of the ascending aorta at the superior border of the Evolut PRO stent. Because of a suspected infected aortic aneurysm caused by prosthetic valve endocarditis (PVE), we performed aortic valve replacement using 23 mm Avalus (Medtronic, Minneapolis, MN, USA) and ascending aortic replacement using 26 mm Gelweave (Vascutek Terumo Inc, Scotland, UK). The postoperative course was uneventful. This report highlights that patients with PVE after TAVR may develop pseudoaneurysms of the ascending aorta.

Abstract
A 94-year-old man who underwent transcatheter aortic valve (TAV) replacement 6 years ago was admitted because of exertional dyspnea. Transthoracic echocardiography revealed severe aortic regurgitation owing to TAV dysfunction. The patient was considered to have a high risk of occlusion of the sinus of Valsalva during TAV-in-TAV. Therefore, we performed TAV-in-TAV concomitant with coronary artery bypass grafting (CABG). The postoperative course was uneventful, and computed tomography 9 months later revealed patency of both the grafts. Concomitant CABG could be considered as one of the options in patients with a high risk of coronary occlusion during TAV-in-TAV.

Abstract
The INSPIRIS RESILIA valve is designed to dilate its valve annulus in transcatheter aortic valve-in-surgical aortic valve (TAV-in-SAV), a catheter therapy for biological valve deterioration. RESILIA tissue has improved anti-calcification properties. An 83-year-old man on hemodialysis undergoing surgical aortic valve replacement (SAVR) with a 25-mm INSPIRIS for severe aortic stenosis 22 months ago presented with general malaise. Transthoracic echocardiography revealed severe bioprosthetic stenosis (peak velocity: 3.5 m/s, mean pressure gradient: 32 mmHg, and effective orifice area: 0.45 cm2) and severely reduced left ventricular function (ejection fraction: 17%). Because redo-SAVR was extremely risky (society of thoracic surgeons [STS] risk score: 31%), the patient underwent transfemoral-TAV-in-SAV using a 26-mm SAPIEN 3️. Pre- and postoperative computed tomography showed that the internal diameter of the INSPIRIS had expanded from 22.2 mm to 24.2 mm. This case demonstrated the dilatable design of INSPIRIS but not the durability of RESILIA tissue.

Abstract
PURPOSE Culture of extracted drains or epicardial pacing wires is an easy and noninvasive method for detecting mediastinitis after open-heart surgery, although studies on its sensitivity and specificity are limited. We, therefore, investigated the usefulness of this approach for diagnosing mediastinitis. METHODS We retrospectively studied the culture results of drains and epicardial pacing wires extracted from 3308 patients. Prediction models of mediastinitis with and without culture results added to clinical risk factors identified by a logistic regression analysis were compared. RESULTS The incidence of mediastinitis requiring surgery was 1.89% (n = 64). Staphylococcus was the causative bacterium in 64.0% of cases. The sensitivity, specificity, and positive and negative predictive values of positive culture results were 50.8%, 91.8%, 10.7%, and 99.0%, respectively. Methicillin-resistant Staphylococcus aureus had the highest positive predictive value (61.5%). A multivariate analysis identified preoperative hemodialysis (OR 5.40 [2.54-11.5], p < 0.01), long operative duration (p < 0.01), postoperative hemodialysis (OR 2.25 [1.01-4.98], p < 0.05), and positive culture result (OR 10.2 [5.88-17.7], p < 0.01) as independent risk factors. The addition of culture results to pre- and postoperative hemodialysis and a lengthy operative time improved the prediction of mediastinitis. CONCLUSIONS A culture survey using extracted drains and epicardial pacing wires may provide useful information for diagnosing mediastinitis.

Abstract
Objective Whereas transcatheter aortic valve replacement is widely implemented, annular rupture is a devastating complication and could be highly mortal. However, owing to its rare incidence, the optimal treatment algorithm has not been established. Thus, we evaluated the feasibility and effectiveness of a 3-step algorithm to treat annulus rupture. Methods From 2009 to 2022, 8 patients of 1083 transcatheter aortic valve implantation (0.8%) developed annulus rupture and were treated with the three-step algorithm. The algorithm was composed of a first step (pericardial drainage and protamine neutralization with blood pressure control), second step (manual hemostatic compression via full/partial sternotomy), and a third step (conservative treatment or radical surgical correction). Results The median age at the procedure was 85 (78-88) years and 7 female patients were included in this study. Two (25%) patients had end-stage renal failure under hemodialysis, and median Society of Thoracic Surgeons score was 8.9% (2.1%-23.2%). The implanted transcatheter heart valves (THVs) were 7 balloon-expandable THVs and 1 self-expandable THV with balloon postdilatation. Under this strategy, 8 (100%) patients underwent pericardial drainage as first step and 5 patients achieved hemostasis. Of these, patient 1 demonstrated bleeding from left sinus of Valsalva and required a Bentall procedure. Although the etiology of this phenomenon was not investigated by contrast-enhanced computed tomography, it might be derived from pseudoaneurysm rupture or delayed annular rupture. In 2 patients, the second step treatment was needed for hemostasis. Third-step treatment was conducted in 1 patient. Postoperatively, 6 patients could be discharged without critical complications whereas 2 patients died during the hospitalization. There were no other complications during the followed-up (584 [7-1614]) days. Conclusions In accordance with the three-step algorithm, 6 patients, including those with high-risk or inoperative status, survived.

Abstract
BACKGROUND There have been few reports on the mid- to long-term safety and efficacy validation of the INSPIRIS RESILIA aortic bioprosthesis (Edwards Lifesciences LLC, Irvine, CA, USA) in Japan. Herein, we report the mid-term results of surgical aortic valve replacement (AVR) for aortic stenosis using INSPIRIS and evaluate the hemodynamics compared to the CEP Magna series from the multicenter AVR registry (the ACTIVIST registry). METHODS Of the 1967 patients who underwent surgical or transcatheter AVR from the ACTIVIST registry, 66 patients who underwent isolated surgical AVR with INSPIRIS by December 2020 were included in this study, and the early and mid-term results were evaluated. Hemodynamics were evaluated by comparing 272 patients undergoing isolated surgical AVR with the Magna group using propensity score matching. RESULTS The mean age was 74.0 ± 7.8 years, and 48.5 % were women. In-hospital mortality was 1.5 %, and the survival rates at 1- and 2-years were 95.2 % and 95.2 %, respectively. After propensity score matching, echocardiographic findings at discharge demonstrated that peak velocity and mean pressure gradient in the INSPIRIS group were comparable, while the effective orifice area in the INSPIRIS group was significantly larger than those in the Magna group (p = 0.048). A patient-prosthesis mismatch at discharge was significantly lower in the INSPIRIS group (11.8 %) than in the Magna group (36.4 %) (p = 0.004). CONCLUSIONS Surgical AVR with INSPIRIS was performed safely and the mid-term results were satisfactory. The hemodynamics of INSPIRIS were comparable to those of Magna.

Abstract
Introduction With the expected increase in patients with heart failure and ischemic 15 cardiomyopathy, the development of myocardial regenerative medicine using cell transplantation as a novel treatment method is progressing. This first-in-human clinical trial aimed to confirm the safety of cardiomyocyte patch transplantation derived from allogeneic induced pluripotent stem (iPS) cells based on the results of several preclinical studies. Study design The inclusion criteria were left ventricular ejection fraction of 35% or less; heart failure symptoms of New York Heart Association class III or higher despite existing therapies such as revascularization; and a 1-year observation period that included a 3-month immunosuppressive drug administration period after transplantation of iPS cell-derived cardiomyocyte patches to evaluate adverse events, cardiac function, myocardial blood flow, heart failure symptoms, and immune response. Results In the first three cases of this trial, no transplanted cell-related adverse events were observed during the 1-year observation period, and improvement in heart failure symptoms was observed. In addition, improvements in left ventricular contractility and myocardial blood flow were observed in two of the three patients. Regarding immune response, an increase in transplant cell-specific antibody titer was observed in all three patients after immunosuppressive drug administration. In one patient with poor improvement in cardiac function and myocardial blood flow, an increase in antibody titer against HLA-DQ was observed even before cell transplantation. Conclusions Our case findings demonstrate that the transplantation of iPS cell-derived cardiomyocyte patches for ischemic cardiomyopathy can be safely performed; however, further investigation of the therapeutic effect and its relationship with an immune response is needed by accumulating the number of patients through continued clinical trials.

Abstract
Objective In patients with ischemic cardiomyopathy, coronary artery bypass grafting ensures better survival than medical therapy. However, the long-term clinical impact of complete revascularization remains unclear. This observational study aimed to evaluate the effects of complete revascularization on long-term survival and left ventricular functional recovery in patients with ischemic cardiomyopathy undergoing coronary artery bypass grafting. Methods We retrospectively reviewed outcomes of 498 patients with ischemic cardiomyopathy who underwent complete (n = 386) or incomplete (n = 112) myocardial revascularization between 1993 and 2015. The baseline characteristics were adjusted using inverse probability of treatment weighting to reduce the impact of treatment bias and potential confounding. The mean follow-up duration was 77.2 ± 42.8 months in survivors. Results The overall 5-year survival rate (complete revascularization, 72.5% vs incomplete revascularization, 57.9%, P = .03) and freedom from all-cause death and/or readmission due to heart failure (54.5% vs 40.1%, P = .007) were significantly greater in patients with complete revascularization than those with incomplete revascularization. After adjustments using inverse probability of treatment weighting, the complete revascularization group demonstrated a lower risk of all-cause death (hazard ratio, 0.61; 95% confidence interval, 0.43-0.86; P = .005) and composite adverse events (hazard ratio, 0.59; 95% confidence interval, 0.44-0.79; P < .001) and a greater improvement in the left ventricular ejection fraction 1-year postoperatively (absolute change: 11.0 ± 11.9% vs 8.3 ± 11.4%, interaction effect P = .05) than the incomplete revascularization group. Conclusions In patients with ischemic cardiomyopathy undergoing coronary artery bypass grafting, complete revascularization was associated with better long-term outcomes and greater left ventricular functional recovery and should be encouraged whenever possible.

Abstract
Transplantation of human allogeneic induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) is a new, promising treatment for severe heart failure. However, immunorejection is a significant concern in allogeneic hiPSC-CM transplantation, requiring the administration of several immunosuppressive agents. An appropriate protocol for the administration of immunosuppressants may substantially affect the efficacy of hiPSC-CM transplantation in case of heart failure owing to allogeneic transplantation. In this study, we investigated the effect of immunosuppressant administration duration on the efficacy and safety of allogenic hiPSC-CM patch transplantation. We used a rat model of myocardial infarction to evaluate cardiac function using echocardiography six months after the transplantation of hiPSC-CM patches with immunosuppressant administration for either two or four months and compared them to control rats (sham operation, no immunosuppressant administration). Histological analysis performed at 6 months after hiPSC-CM patch transplantation revealed significant improvement in cardiac function in immunosuppressant-treated rats compared with those in the control group. Moreover, fibrosis and cardiomyocyte size was significantly reduced and the number of structurally mature blood vessels was significantly increased in the immunosuppressant-treated rats compared to control rats. However, there were no significant differences between the two immunosuppressant-treated groups. Our results show that prolonged administration of immunosuppressive agents did not enhance the effectiveness of hiPSC-CM patch transplantation, and therefore, highlight the importance of an appropriate immunological regimen for the clinical application of such transplantation.

Abstract
Fulminant myocarditis (FM) requiring temporary mechanical circulatory support (t-MCS) has a high mortality rate. Peripheral veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and intra-aortic balloon pump (IABP) are sometimes insufficient to induce cardiac recovery. For patients with FM refractory to VA-ECMO with IABP, we have applied a biventricular assist device (BIVAD) or Impella to unload the left ventricle and to fully support the systemic circulation. In the last 10 years, 37 refractory FM patients histologically diagnosed with myocarditis and who did not recover with VA-ECMO were treated with BIVAD (n = 19) or Impella (n = 18). No significant difference was found between the Impella and BIVAD groups in preoperative findings other than serum creatinine level. Seventeen of 18 patients in the Impella group were successfully weaned from t-MCS in 9 (6-12) days. Conversely, the temporary BIVAD was removed in 21 (11-38) days in 10 of 19 patients. Six patients died while on temporary BIVAD because of multiple organ failure and cerebral bleeding, and three patients required conversion to implantable VAD. Compared with BIVAD, left ventricular unloading with Impella could be less invasive and could promote cardiac recovery in refractory FM patients. The Impella has the potential to provide effective temporary MCS for FM patients.

Abstract
A 48-year-old male patient developed acute myeloid leukemia (AML) with t(3;3)(q21.3;q26.2) chromosomal mutation 8 months after orthotopic heart transplantation from a human leukocyte antigen-unmatched brain-dead donor for cardiac sarcoidosis. He had sequelae of stroke and chronic renal failure at the time of AML diagnosis. He received 3 cycles of azacitidine and venetoclax induction therapy and achieved complete hematological remission with incomplete count recovery without causing severe complications, including infection. He sequentially underwent allogeneic peripheral blood stem cell transplantation from a HLA-8/8 matched, ABO-blood matched, unrelated female donor and successfully achieved donor cell engraftment. His transplanted heart was viable, and the coronary vessels were not damaged even after allogeneic peripheral blood stem cell transplantation. Although AML relapsed afterward, azacytidine/venetoclax was a tolerable bridging therapy even for early-onset AML after heart transplantation.

Abstract
Background YS-1402, which is a polymerized form of the synthetic prostacyclin agonist ONO-1301, has been proven in several preclinical studies to induce therapeutic effects for patients with ischemic cardiomyopathy (ICM). In this human study, we assessed the safety, tolerability, and efficacy of YS-1402, combined with coronary artery bypass grafting (CABG), for ICM. Methods Twenty-four patients with ICM whose left ventricular ejection fraction was <40% with an indication for CABG were double-blindly assigned to four groups: placebo, 10-mg YS-1402, 30-mg YS-1402, and 100-mg YS-1402. YS-1402 or placebo medications were administered on the surface of the left ventricle at the time of the CABG. Pre- and postoperative cardiac function and myocardial blood flow were assessed for 6 months postoperatively, along with a safety assessment. Results No severe adverse events were related to YS-1402. The maximum blood concentration of ONO-1301 was less than that of the no observable adverse effect level. Significantly increased myocardial blood flow (MBF) and cardiac function were observed in the YS-1402 group 26 weeks postoperatively, although no improvement in MBF occurred in the placebo group. Conclusion This Phase I/IIa parallel group-controlled, dose-escalation study of YS-1402 combined with CABG for ICM demonstrated the safety, tolerability, and potential efficacy of YS-1402.

Abstract
BACKGROUND Coronary artery access after repeat transcatheter aortic valve replacement (TAV-in-TAV) is reportedly more difficult because leaflet displacement of the first transcatheter heart valve (THV) impairs coronary cannulation; however, its effects in small patients are unknown. This study aimed to simulate coronary accessibility after TAV-in-TAV in patients of small body size. METHODS We retrospectively analyzed computed tomography scans after initial THV implantation and classified patients by THV and coronary artery location, valve-to-aorta distance, and valve-to-coronary distance. Risks were compared between the SAPIEN and CoreValve/Evolut series, among THV generations, and between bicuspid and tricuspid aortic valves in the CoreValve/Evolut series. RESULTS A total of 254 patients (SAPIEN series, n = 164; CoreValve/Evolut series, n = 90) were enrolled. The average body surface area of the patients was 1.44 m2. Patients were classified as "feasible" (26%), "theoretically feasible with low risk" (19.7%), "theoretically feasible with high risk" (8.7%), or "unfeasible" (45.8%). The "unfeasible" rate was significantly higher in the CoreValve/Evolut series than in the SAPIEN series (78.9% vs 26.2%; P < .001). A significantly higher "unfeasible" rate was identified in the current model of SAPIEN (SAPIEN, 8.3%; SAPIENXT, 1.8%; SAPIEN3, 48.2%; P < .001), but not in the CoreValve/Evolut series (CoreValve, 83.3%; Evolut R, 80.0%; Evolut PRO, 71.4%; P = .587). Patients with a bicuspid aortic valve had a lower "unfeasible" rate compared to those with a tricuspid aortic valve (60.0% vs 86.2%; P = .014). CONCLUSIONS Patients of small body size may have a high probability of "unfeasible" coronary access after TAV-in-TAV, especially when treated with current high-frame devices, suggesting the need for careful strategic planning for initial THV implantation.

Abstract
Objectives The study objectives were to determine the incidence, predictors, and clinical impact of ventricular arrhythmias after coronary artery bypass grafting and to evaluate the impact of implantable cardioverter defibrillators on the survival of patients with ventricular arrhythmias. Methods We enrolled 498 patients with a left ventricular ejection fraction of 40% or less who underwent coronary artery bypass grafting between 1993 and 2015. Clinical follow-up was completed in 94.0% of patients, with a median follow-up of 58.4 months. Results Overall, 212 patients (43%) died, mainly of heart failure (n = 54, 10.8%) or sudden cardiac death (n = 40, 8.0%). The sudden cardiac death rate was highest during the first 6 months, with a monthly rate of 0.37%. Overall, 99 patients (20%) developed postoperative ventricular arrhythmias, and implantable cardioverter defibrillator was implanted in 55 patients. Previous ventricular arrhythmias (hazard ratio, 3.22; 95% confidence interval, 1.98-5.24; P < .001), left ventricular end-systolic dimension (hazard ratio, 1.07; 95% confidence interval, 1.04-1.10; P < .001), and myocardial infarction in the left anterior descending artery territory (hazard ratio, 1.73; 95% confidence interval, 1.10-2.73; P = .02) were independent predictors of postoperative ventricular arrhythmias. Notably, the 5-year survival of patients with ventricular arrhythmias who received an implantable cardioverter defibrillator was significantly higher than that of patients with ventricular arrhythmias who did not receive it (76.1% vs 22.7%, P < .001) and was comparable to that of patients without ventricular arrhythmias (76.1% vs 73.6%, P = .98). Conclusions Sudden cardiac death affects a significant proportion of patients with ischemic cardiomyopathy undergoing coronary artery bypass grafting, most frequently within 6 months postoperatively. To prevent sudden cardiac death, earlier implantable cardioverter defibrillator implantation should be indicated for high-risk patients with scars in the left anterior descending artery territory and excessive left ventricular remodeling.

Abstract
Background Although transcatheter aortic valve replacement (TAVR) has demonstrated favorable outcomes in randomized studies, there remains a sizable group of patients in whom TAVR may be futile. Characterizing the survival rate in a wide array of patients undergoing TAVR can help develop effective strategies for improving the allocation of medial resources. Objectives The aim of this study was to develop a risk model to estimate 1-year mortality after TAVR from a representative nationwide registry in Japan. Methods The J-TVT (Japan Transcatheter Valve Therapies) registry contains complete data, including 1-year outcomes, on patients undergoing TAVR in Japan. A total of 17,655 patients underwent TAVR between 2013 and 2018. They were randomly divided into 2 groups in a 7:3 ratio to form a derivation cohort of 12,316 patients and a validation cohort of 5,339 patients. A risk model was constructed for 1-year mortality in the derivation cohort, and its discrimination and calibration were assessed in the validation cohort. Results The mean age of all registered patients was 84.4 years, and 68.8% were women. The mean body size area was 1.43 m2, and the mean Society of Thoracic Surgeons Predicted Risk of Mortality score was 7.3%. The estimated 1-year survival was 91.8%; 202 and 1,316 deaths were observed at 30 days and 1 year, respectively; The estimated C index for the developed model was 0.733 (95% CI: 0.709-0.757) in the validation cohort, with good calibration. Conclusions A prediction model for 1-year survival following TAVR derived from a national clinical database performed well and should aid physicians managing TAVR patients.

Abstract
A pump infection is a fatal complication specific to left ventricular assist devices. Infection recurrence is a major concern when device exchange is indicated for pump infection. In the present case, we used the Impella 5.0 to maintain proper hemodynamics and to treat the infection in the absence of an implantable device. We demonstrate that the Impella 5.0 can serve as an effective bridge for device exchange by controlling infection and minimizing organ dysfunction, despite prolonged management.

Abstract
The loss of functional cells through immunological rejection after transplantation reduces the efficacy of regenerative therapies for cardiac failure that use allogeneic induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs). Recently, mixed-chimera mice with donor-specific immunotolerance have been established using the RGI-2001 (liposomal formulation of α-galactosyl ceramide) ligand, which activates invariant natural killer T (iNKT) cells. The present study aimed to investigate whether mixed chimerism, established using RGI-2001, prolongs graft survival in allogeneic iPSC-CM transplantation. Mixed-chimera mice were established via combinatorial treatment with RGI-2001 and anti-CD154 antibodies in an irradiated murine bone marrow transplant model. Luciferase-expressing allogeneic iPSC-CMs were transplanted into mixed-chimera and untreated mice, followed by in vivo imaging. RGI-2001 enhanced iNKT cell activation in mice, and mixed chimerism was successfully established. In vivo imaging revealed that while the allografts were completely obliterated within 2 weeks when transplanted to untreated mice, their survivals were not affected in the mixed-chimera mice. Furthermore, numerous CD3+ cells infiltrated allografts in untreated mice, but fewer CD3+ cells were present in mixed-chimera mice. We conclude that mixed-chimera mice established using RGI-2001 showed prolonged graft survival after allogeneic iPSC-CM transplantation. This donor-specific immunotolerance might increase the efficacy of regenerative therapies for heart failure with allogeneic iPSC-CMs.

Abstract
Perioperative stroke is one of the most serious complications after transcatheter aortic valve replacement (TAVR), and it should be especially noted in patients with an atheroma in the ascending aorta. Here, we report the first experience of transfemoral (TF)-TAVR with the insertion of a filter device for two patients with severe aortic stenosis who were incidentally detected a grade 4 atheroma in the ascending aorta preoperatively. The patients had a favorable postoperative course without any cerebrovascular events or procedure-related complications.

Abstract
In this article, we analyzed 114 adult heart transplantation( HTx) cases from 1999 to 2021. Of these cases, 94% of patients underwent left ventricular assist device ( LVAD) implantation before HTx. The mean period of LVAD support was 3.0 ±1.2 years. Thirty-day mortality was 0.8% and the 10-year survival rate was 89% after HTx. Preoperative and postoperative renal function was the prognostic factors. Long LVAD support was not associated with the long-term survival after HTx.

Abstract
The management of macrolide-resistant Mycobacterium avium complex (MAC) disease is challenging. It is extremely rare for non-human immunodeficiency virus (HIV)-infected patients to develop disseminated MAC disease. A 73-year-old non-HIV-infected woman was diagnosed with MAC lung disease (MAC-LD) for 20 years and subsequently chronic necrotizing pulmonary aspergillosis for three years. To avoid drug interaction between rifampicin and voriconazole, MAC-LD was treated with clarithromycin (CLR) alone. The results of the bone biopsy and bone marrow culture conducted for back pain were compatible with CLR-resistant MAC vertebral osteomyelitis. The clinical management of CLR-resistant disseminated MAC disease consisting of lung and spinal lesions with no established treatment and a poor prognosis is challenging. In this case, the patient was treated with multidrug antibiotic therapy, including CLR, ethambutol, rifampicin, amikacin, and moxifloxacin. The results show the effectiveness of multidrug antibiotic therapy in treating CLR-resistant disseminated MAC disease.

Abstract
BACKGROUND This study aimed to clarify the incidence and determinants of postoperative adverse events in patients with ischemic cardiomyopathy who achieved long-term durable mitral valve repair. METHODS Between 1999 and 2015, 166 patients with chronic ischemic mitral regurgitation (MR) and left ventricular (LV) ejection fraction ≤40% underwent restrictive mitral annuloplasty. During follow-up (65±34 months), echocardiographic assessments were performed 809 times (mean, 4.9±2.4 times) and 20 patients who had developed postoperative recurrent MR (≥moderate) were excluded. Finally, 146 patients (68±9 years) whose MR was well controlled over time were included. RESULTS A total of 61 mortalities and/or 27 readmissions for heart failure were observed in 76 patients (52%). Among hospital survivors, age (adjusted hazard ratio: 1.05; P=0.001), and estimated glomerular filtration rate (adjusted hazard ratio: 0.61; P=0.001) were identified as independent predictors of long-term mortality and/or readmission for heart failure. The degree of LV function recovery after surgery was comparable between patients with and without adverse events. However, the former group showed greater values for systolic pulmonary artery pressure, tricuspid regurgitation severity, inferior vena cava dimension, and plasma brain natriuretic peptide level throughout the follow-up period (group effect p<0.05 for all). CONCLUSIONS Approximately 50% of patients died or were hospitalized for heart failure even in the absence of recurrent mitral regurgitation during the 5-year follow-up, indicating that durable mitral repair does not always lead to favorable clinical outcomes. The adverse events might be related to volume overload secondary to impaired renal function and less favorable pulmonary hemodynamics.

Abstract
Objective We investigated whether or not a history of multiple percutaneous coronary interventions (PCIs) is associated with clinical outcomes after surgery for ischemic mitral regurgitation. Methods A total of 309 patients with chronic ischemic mitral regurgitation and left ventricular ejection fraction ≤40% who underwent restrictive mitral annuloplasty were classified as follows: patients with no or 1 previous PCI (nonmultiple PCI group [n = 211]) and patients with 2 or more previous PCIs (multiple PCIs group [n = 98]). Mean follow-up duration was 53 ± 40 months. Results Before surgery, there were no intergroup differences in patient demographic characteristics except for lower estimated glomerular filtration rate in patients with multiple PCIs. These patients underwent concomitant coronary artery bypass grafting less frequently with a lower number of distal anastomoses (P < .05 for both). The 30-day mortality was 3.3% and 2.0% in the nonmultiple and multiple PCIs group, respectively (P = .72). During follow-up, there were 157 deaths. Patients with multiple PCIs showed lower 5-year survival rate (44% vs 64%; P = .002). After adjustments with inverse-probability-of-treatment weighting, multiple PCIs history was an independent risk factor for mortality (adjusted hazard ratio, 1.4; 95% confidential interval, 1.1-1.7; P = .002). Patients with multiple PCIs showed less improvement in left ventricular ejection fraction (interaction effect P < .001). Conclusions In patients with ischemic mitral regurgitation, a history of previous multiple PCIs was associated with increased risk of long-term postoperative mortality, with less improvement in left ventricular ejection fraction.

Abstract
The arrival of modern humans into previously unoccupied island ecosystems is closely linked to widespread extinction, and a key reason cited for Pleistocene megafauna extinction is anthropogenic overhunting. A common assumption based on late Holocene records is that humans always negatively impact insular biotas, which requires an extrapolation of recent human behavior and technology into the archaeological past. Hominins have been on islands since at least the early Pleistocene and Homo sapiens for at least 50 thousand y (ka). Over such lengthy intervals it is scarcely surprising that significant evolutionary, behavioral, and cultural changes occurred. However, the deep-time link between human arrival and island extinctions has never been explored globally. Here, we examine archaeological and paleontological records of all Pleistocene islands with a documented hominin presence to examine whether humans have always been destructive agents. We show that extinctions at a global level cannot be associated with Pleistocene hominin arrival based on current data and are difficult to disentangle from records of environmental change. It is not until the Holocene that large-scale changes in technology, dispersal, demography, and human behavior visibly affect island ecosystems. The extinction acceleration we are currently experiencing is thus not inherent but rather part of a more recent cultural complex.

Abstract
Aggregatibacter actinomycetemcomitans, an etiological agent associated with periodontitis, endocarditis, and other infections, has rarely been implicated in spondylitis. A 70-year-old man with aortic valve replacement presented with a 4-month history of lower back pain and was diagnosed with spondylitis. Prolonged incubation of blood cultures and a biopsy yielded A. actinomycetemcomitans. Concurrent infective endocarditis (IE) was probable considering the infectious organism and the patients' prosthetic valve. The patient was treated with ceftriaxone and recovered well. Pyogenic spondylitis with possible concurrent IE may be caused by A. actinomycetemcomitans. Extended incubation and repeated cultures should be considered if Haemophilus spp., Aggregatibacter spp, Cardiobacterium spp, Eikenella spp, and Kingella spp. (HACEK) infection is suspected.

Abstract
BACKGROUND Although induced pluripotent stem (iPS) cell-derived cardiac constructs may have a potential in cardiomyogenesis of a distressed myocardium, obtaining polarity in cardiac constructs, such as via myocyte alignment, may be crucial to achieve a maximum contractile force for better clinical outcomes. We herein hypothesized that transplantation of an aligned cardiac tissue derived from iPS cells has therapeutic effects in a porcine ischemic cardiomyopathy model as a preclinical trial. METHODS Aligned cardiac tissues were developed by culturing high-purity iPS cell-derived cardiomyocytes in xeno-free conditions and transplanting them into infarct porcine hearts (iPS-CM group, n = 7; control, n = 6). Three months after treatment, therapeutic efficacy was evaluated functionally and histologically. RESULTS In vitro assessment revealed that the aligned cardiac tissue containing high purity cardiomyocytes contracted homogeneously and had excellent mechanical properties. In the in vivo study, the left ventricular ejection fraction of the iPS-CM group was significantly greater than that of the control group, 3 months after transplantation (37.8% ± 2.3% vs 28.3% ± 2.5%, p < 0.05). Pathologically, attenuated interstitial fibrosis, attenuation of hypertrophied cardiomyocytes, and an increased capillary density were also prominent in the iPS-CM group. A limited amount of engraftment of the transplanted tissue maintaining tissue alignment was observed at 2 weeks after transplantation. CONCLUSIONS The creation of large-scale functional aligned cardiac tissue was feasible, and the transplantation of the aligned tissue improved cardiac function with angiogenesis and antifibrotic effects in a porcine cardiomyopathy model.

Abstract
Background This study retrospectively examined the association between elevated trans-pulmonary gradient (TPG), which reflects pre-capillary contribution to pulmonary hypertension (PH), and postoperative pulmonary hemodynamics and outcomes following restrictive mitral annuloplasty (RMA) in patients with pre-existing PH. Methods Pre- and postoperative (1 month) cardiac catheterization was performed in 64 patients with severely impaired left ventricular function (i.e., ejection fraction ≤40%) and pre-existing PH (mean pulmonary artery pressure (PAP) ≥25 mmHg) who underwent RMA. Patients were segregated into two groups: low TPG (≤12 mmHg) and elevated TPG (>12 mmHg). The mean follow-up period was 54±27 months. The primary outcome seen was a change in pulmonary hemodynamics after RMA; secondary outcomes were composite adverse events, including all-cause mortality and readmission for heart failure. Results Compared to the low TPG group, patients in the elevated TPG group were more likely to show a postoperative mean PAP of ≥25 mmHg (84% vs. 38%), TPG of >12 mmHg (79% vs. 11%), and pulmonary vascular resistance of ≥240 dynes/sec/cm−5 (84% vs. 6.7%) (all P<0.001), although both groups showed comparable degrees of mitral regurgitation improvement. Serial echocardiography demonstrated that Doppler-derived systolic PAP, which once decreased in both groups, remained stable in the low group while steadily increasing in the elevated group (group effect P<0.001). Patients with elevated TPG had lower freedom from composite adverse events (5-year, 20% vs. 70%, P=0.003). After adjusting for baseline covariates, the elevated TPG was independently associated with increased risk of adverse events (adjusted hazard ratio 2.9, 95% CI: 1.2–6.9, P=0.017). Conclusions Elevated TPG negatively affects postoperative pulmonary hemodynamics and late outcomes in patients with advanced cardiomyopathy and pre-existing PH who have undergone RMA. These findings suggest that the assessment of TPG should be included in post-RMA risk stratification.

Abstract
Background In this study, we evaluated the prevalence of tricuspid regurgitation (TR) worsening in patients with left ventricular assist devices (LVADs) and its impact on late right ventricular (RV) failure. Methods We enrolled 147 patients of the 184 patients who underwent continuous-flow LVAD implantations from 2005 to March 2018. The prevalence of postoperative TR worsening and late RV failure were retrospectively evaluated. Results Concomitant tricuspid annuloplasty (TAP) was performed in 28 of 41 patients (68%) with preoperative TR greater than or equal to moderate (TR group) and in 23 of 106 patients (22%) with preoperative TR less than or equal to mild (non-TR group). Regarding the TR-free rates, despite receiving or not receiving concomitant TAP, there was no significant difference between the 2 groups (TR group: p = 0.37; non-TR group: p = 0.42). Of the 9 patients with postoperative TR greater than or equal to moderate, late RV failure developed in 3 patients, with TR worsening after RV failure in each case. During follow-up, 16 patients (11%) had late RV failure. As for the late RV failure-free rates, despite receiving or not receiving concomitant TAP, there was no significant difference between the 2 groups (TR group: p = 0.37; non-TR group: p = 0.96). Conclusions TR prognosis was preferable regardless of a patient receiving concomitant TAP; however, the presence of postoperative TR seemed to unrelated to late RV failure. Prophylactic TAP might not be necessary to prevent late RV failure. Supplementary Information The online version contains supplementary material available at 10.1186/s13019-021-01492-0.

Abstract
BACKGROUND In patients with severe left ventricular (LV) dysfunction requiring coronary artery bypass grafting (CABG), the association between diabetic status and outcomes after surgery, as well as with survival benefit following bilateral internal thoracic artery (ITA) grafting, remain largely unknown.Methods and Results:Patients (n=188; mean [±SD] age 67±9 years) with LV ejection fraction ≤40% who underwent isolated initial CABG were classified into non-diabetic (n=64), non-insulin-dependent diabetic (NIDM; n=74), and insulin-dependent diabetic (IDM; n=50) groups. During follow-up (mean [±SD] 68±47 months), the 5-year survival rate was 84% and 65% among non-diabetic and diabetic patients, respectively (P=0.034). After adjusting for all covariates, both NIDM and IDM were associated with increased mortality, with hazard ratios (HRs) of 1.9 (95% confidence interval [CI] 1.0-3.7; P=0.049) and 2.4 (95% CI 1.2-4.8; P=0.016), respectively. Among non-diabetic patients, there was no difference in the 5-year survival rate between single and bilateral ITA grafting (86% vs. 80%, respectively; P=0.95), whereas bilateral ITA grafting increased survival among diabetic patients (57% vs. 81%; P=0.004). Multivariate analysis revealed that bilateral ITA was significantly associated with a decreased risk of mortality (HR 0.3; 95% CI 0.1-0.8; P=0.024). CONCLUSIONS NIDM and IDM were significantly associated with worse long-term clinical outcome after CABG for severe LV dysfunction. Bilateral ITA grafting has the potential to improve survival in diabetic patients with severe LV dysfunction.

Abstract
OBJECTIVES This retrospective study aimed to clarify the incidence, determinants and clinical impact of left ventricular (LV) function non-recovery after coronary artery bypass grafting (CABG) in patients with ischaemic cardiomyopathy. METHODS A total of 490 patients with ischaemic cardiomyopathy (LV ejection fraction ≤ 40%) undergoing CABG were analysed. Follow-up echocardiography was performed at 1 month, 1 year, and annually thereafter. LV function recovery was defined as ejection fraction (EF) ≥40% at least once during follow-up. LV function non-recovery was defined as EF <40% at any follow-up. The primary and secondary end points were changes in LV function and all-cause mortality, respectively. Clinical follow-up was completed in 461 patients (94.1%; mean follow-up: 64.5 ± 45.5 months). RESULTS During follow-up, echocardiographic assessments were performed 1863 times (mean, 3.8 ± 2.4), and 193 patients (39.4%) exhibiting LV function non-recovery were identified. Overall survival was significantly higher in the recovery group (53.9%) than in the non-recovery group (31.4%) at 10 years (P < 0.001). Independent predictors of LV function non-recovery were preoperative LV end-systolic diameter [odds ratio (OR) 1.07, 95% confidence interval (CI) 1.04-1.10; P < 0.001] and bilateral internal thoracic artery grafting (OR 0.61, 95% CI 0.39-0.95; P = 0.028). In a multivariable Cox proportional hazards model, LV function non-recovery was significantly associated with all-cause mortality (hazard ratio 2.14, 95% CI 1.60-2.86; P < 0.001). CONCLUSIONS Almost 40% of patients with ischaemic cardiomyopathy undergoing CABG did not achieve LV function recovery and were associated with poor prognosis. To achieve LV function recovery, CABG with bilateral internal thoracic artery may be recommended before excessive LV remodelling occurs.

Abstract
Ventricular septal rupture after acute myocardial infarction is a fatal complication with a very high in-hospital mortality. Herein, we describe a new repair technique using a 1st patch for exclusion of the infarcted myocardium and a 2nd sutureless patch for rupture site closure with a novel tissue adhesive (Hydrofit®). Follow-up of over 2 years revealed a good clinical course and no residual interventricular shunt on echocardiography. This modified infarct exclusion technique with a 2nd sutureless patch has a benefit of avoiding stitches to the fragile infarcted myocardium and might be effective in preventing interventricular shunt recurrence after ventricular septal rupture.

Abstract
Background:
Cardiogenic shock due to acute severe mitral regurgitation is characterized by multiple organ failure and acute pulmonary edema, leading to a high risk of mortality. Methods and Results:
We report on a patient with acute, severe mitral regurgitation complicated by cardiogenic shock, refractory to both inotrope treatment and intra-aortic balloon pump support. The patient was successfully bridged to surgery with an Impella CP, a percutaneous left ventricular assist device. Conclusions:
Mechanical support using an Impella CP can stabilize hemodynamics and may be used as a bridge to elective surgery for patients with mitral regurgitation with cardiogenic shock.

Abstract
Significant aortic regurgitation (AR) is a common complication after continuous-flow left ventricular assist device (LVAD) implantation. Using machine-learning algorithms, this study was designed to examine valuable predictors obtained from LVAD sound and to provide models for identifying AR. During a 2-year follow-up period of 13 patients with Jarvik2000 LVAD, sound signals were serially obtained from the chest wall above the LVAD using an electronic stethoscope for 1 min at 40,000 Hz, and echocardiography was simultaneously performed to confirm the presence of AR. Among the 245 echocardiographic and acoustic data collected, we found 26 episodes of significant AR, which we categorized as “present”; the other 219 episodes were characterized as “none”. Wavelet (time–frequency) analysis was applied to the LVAD sound and 19 feature vectors of instantaneous spectral components were extracted. Important variables for predicting AR were searched using an iterative forward selection method. Seventy-five percent of 245 episodes were randomly assigned as training data and the remaining as test data. Supervised machine learning for predicting concomitant AR involved an ensemble classifier and tenfold stratified cross-validation. Of the 19 features, the most useful variables for predicting concomitant AR were the amplitude of the first harmonic, LVAD rotational speed during intermittent low speed (ILS), and the variation in the amplitude during normal rotation and ILS. The predictive accuracy and area under the curve were 91% and 0.73, respectively. Machine learning, trained on the time–frequency acoustic spectra, provides a novel modality for detecting concomitant AR during follow-up after LVAD.

Abstract
BACKGROUND Consensus regarding an optimal atrial fibrillation (AF) ablation lesion set concomitant with aortic valve replacement (AVR) and/or coronary artery bypass grafting (CABG) has not been established. METHODS We enrolled 125 consecutive patients (89 men; 70 ± 8 years old) with persistent AF who underwent radiofrequency-based pulmonary vein isolation (PVI) (PVI group, n = 53) or a Cox-Maze procedure (Maze group, n = 72) with AVR and/or CABG. To reduce the impact of treatment bias and potential confounding in the direct comparisons between patients who underwent Cox-Maze with and those who underwent PVI, we established weighted Cox proportional-hazards regression models with inverse probability of treatment weighting. Mean follow-up was 63 ± 34 months (maximum, 154 months). RESULTS There was 1 in-hospital death in each group. Patients who underwent Cox-Maze showed a higher freedom from AF at all follow-up examinations. After the operation, there were 32 deaths, 13 thromboembolisms, 8 hemorrhagic events, and 22 heart failure readmissions. The Maze group had higher rates for 5-year survival (88% vs 64%, P = .013) and freedom from composite events (74% vs 42%, P < .001). After adjustment with inverse probability of treatment weighting, the Cox-Maze procedure still showed a lower risk of overall mortality (adjusted hazard ratio, 0.38; 95% confidence interval, 0.21-0.66; P = .001) and composite adverse events (adjusted hazard ratio, 0.52; 95% confidence interval, 0.35-0.76; P = .001). CONCLUSIONS In patients with persistent AF indicated for nonmitral valve surgery, a concomitant Cox-Maze procedure resulted in superior AF- and event-free survival compared with PVI, without increased risk of early mortality. These findings may assist decision making for surgical management of persistent AF concomitant with AVR and/or CABG.

Abstract
Infection is a major complication in patients with a left ventricular assist device (LVAD). Once a driveline exit-site infection (DLI) reaches the LVAD component, LVAD exchange may become necessary for radical treatment, although clinical results are not satisfactory. In this report, we describe two cases of LVAD infection successfully treated with pump exchange. During LVAD support, the DLI extended into the pump pocket and the outflow graft despite aggressive surgical debridement and negative pressure wound therapy. These two patients required LVAD exchange for radical treatment, because the estimated waiting period for heart transplantation was at least more than 1 year. The LVAD exchange was performed through median re-sternotomy, and the infected HeartWare ventricular assist device (HVAD) was completely removed under cardiopulmonary bypass. Then, a new LVAD covered with the omentum flap was implanted. These two patients were successfully bridged to heart transplantation after 10 months and 2 years of support without recurrence of infection. These two cases may suggest that the driveline of the HVAD needs to be kept away from the outflow graft to prevent refractory outflow graft infection.

Abstract
We evaluated the cardiac function recovery following skeletal myoblast cell-sheet transplantation and the long-term outcomes after applying this treatment in 23 patients with ischemic cardiomyopathy. We defined patients as “responders” when their left ventricular ejection fraction remained unchanged or improved at 6 months after treatment. At 6 months, 16 (69.6%) patients were defined as responders, and the average increase in left ventricular ejection fraction was 4.9%. The responders achieved greater improvement degrees in left ventricular and hemodynamic function parameters, and they presented improved exercise capacity. During the follow-up period (56 ± 28 months), there were four deaths and the overall 5-year survival rate was 95%. Although the responders showed higher freedom from mortality and/or heart failure admission (5-year, 81% versus 0%; p = 0.0002), both groups presented an excellent 5-year survival rate (5-year, 93% versus 100%; p = 0.297) that was higher than that predicted using the Seattle Heart Failure Model. The stepwise logistic regression analysis showed that the preoperative estimated glomerular filtration rate and the left ventricular end-systolic volume index were independently associated with the recovery progress. Approximately 70% of patients with “no-option” ischemic cardiomyopathy responded well to the cell-sheet transplantation. Preoperative renal and left ventricular function might predict the patients’ response to this treatment.

Abstract
Abstract
Background
BIOSCIENCE randomized trial which compared biodegradable-polymer sirolimus-eluting stents with ultra-thin (60μm) strut (ultra-thin BP-SES) and durable-polymer everolimus-eluting stents with thin (81μm) strut (thin DP-EES) have reported that definite stent thrombosis within 1 year had more frequently occurred in ultra-thin BP-SES (0.9%) than in thin DP-EES group (0.4%) although it was not statistically significant. It suggests that neointimal coverage after stent implantation within 1 year might be different between ultra-thin BP-SES and thin DP-EES. Recently, two types of biogradable-polymer sirorimus eluting stents, thin (80μm) strut type (thin BP-SES) and ultra-thin (60μm) strut type (ultra-thin BP-SES), can be available in clinical settings.
Purpose
We compared neointimal coverage conditions between ultra-thin BP-SES and thin BP-SES by optical coherence tomography (OCT).
Methods
Consecutive Forty-six patients who underwent 21 ultra-thin BP-SESs or 25 thin BP-SESs implantation were enrolled. We compared incidences of acute coronary syndrome, type B2/C lesion, atherectomy device use, stent size, stent length, maximum inflation pressure, and 8-month follow-up OCT parameters including proportions of uncovered struts (%Uncovered), malapposed struts, (%Mallaposed) and mean neointimal hyperplasia thickness (mean NHT) between the two groups.
Results
%Uncovered and %malapposed were significantly higher and mean NHT was significantly lower in ultra-thin BP-SES than in thin BP-SES (Table). The other parameters were similar between the two groups.
Conclusion
Ultra-thin BP-SES showed worse neointimal coverage as compared to thin BP-SES within 1 year after stent implantation, which may increase stent thrombosis.

Abstract
Abstract
Background
Little has been reported on the outcome of contact force (CF)-guided radiofrequency catheter ablation (RFCA) and second generation cryoballoon ablation (CBA).
Purpose
The purpose of this study was to compare the outcome of CF-guided RFCA and second generation CBA for paroxysmal atrial fibrillation (PAF).
Methods
We enrolled the consecutive 364 patients with PAF who underwent initial ablation between September 2014 and July 2018 in our hospital. We compared the late recurrence of atrial tachyarrhythmia more than three months after ablation between RFCA group and CBA group. All RFCA procedures were performed using CF-sensing catheter and all CBA procedures were performed using second generation CB.
Results
There were significant differences in background characteristics: chronic kidney disease, serum brain natriuretic peptide level, and left ventricular ejection fraction. After propensity score matched analysis (Table), atrial tachyarrhythmia free survival was significantly higher in CBA group than in RFCA group (Figure).
Conclusions
Second generation CBA showed a significantly lower late recurrence rate compared to CF-guided RFCA.

Abstract
OBJECTIVES Although concomitant surgery for coronary artery disease (CAD) and thoracic aortic aneurysm is performed often, the long-term patency of the coronary artery bypass grafting (CABG) anastomosed to a vascular prosthesis has not been fully investigated. Here, we explored the long-term patency of the graft in comparison with the proximal anastomosis site on the native ascending aorta or vascular prosthesis. METHODS A total of 84 patients with concomitant CABG who underwent surgery for thoracic aortic aneurysm at 3 Osaka Cardiovascular Research Group institutes were retrospectively investigated for this study. The patency of 109 aortocoronary bypasses using saphenous vein grafts was evaluated with computed tomography angiography or coronary angiography, comparing the grafts anastomosed on the vascular prosthesis (group P, n = 75) to those anastomosed on the native ascending aorta (group N, n = 34). RESULTS During 45.9 ± 39.7 months follow-up, significantly worse patency of the grafts in group P was revealed when compared with those in group N (100% vs 77.6% in 12 months, 100% vs 52.7% in 36 months and 100% vs 31.6% in 57 months, log rank P < 0.001). The poor patency of the grafts was confirmed in each target lesions (left anterior descending artery: P = 0.050, right coronary artery: P = 0.045, left circumflex artery: P = 0.051) and regardless of the severities of the target coronary vessels (severe stenosis: P = 0.013, mild-to-moderate stenosis: P = 0.029). Furthermore, an analysis of graft occlusion risk factors using the univariate Cox proportional hazards model revealed that the proximal anastomosis site on the vascular prosthesis was the sole risk factor for graft occlusion (P < 0.001). CONCLUSIONS In the simultaneous surgery for CAD and thoracic aortic aneurysm, CABG design from vascular prosthesis to coronary artery should be avoided if possible, although further studies are warranted.

Abstract
Aims In patients with ischaemic mitral regurgitation (MR), the impact of mitral valve surgery with concomitant coronary artery bypass grafting (CABG) on post‐operative survival and left ventricular (LV) reverse remodelling remains unknown. Therefore, we investigated these outcomes following restrictive mitral annuloplasty (RMA) with and without CABG in those patients. Methods and results This study included 309 patients with chronic MR and ischaemic cardiomyopathy for whom concomitant CABG was indicated (n = 225) or not indicated (n = 84) with RMA. The primary endpoint was all cause mortality during the follow‐up, and the secondary endpoint was defined as the composite of mortality and re‐admission for heart failure. Linear mixed model was used to analyse serial echocardiographic changes in LV function. To reduce the impact of treatment bias and potential confounding in the direct comparisons between patients who underwent RMA with and those who underwent it without CABG, we established weighted Cox proportional‐hazards regression models with inverse‐probability‐of‐treatment weighting. Pre‐operatively, there were no intergroup differences in age (RMA with CABG, 67 ± 9 vs. RMA without CABG, 68 ± 11, P = 0.409) and logistic EuroSCORE II (16 ± 14 vs. 15 ± 15%, P = 0.496). The 30‐day mortalities were 2.7% and 3.6%, respectively (P = 0.67). During follow‐up with a mean duration of 72 ± 37 months (range, 5.6–179), there were 157 deaths and 105 re‐admissions for heart failure. Overall 1‐year and 5‐year survival rates were 83 ± 2% and 58 ± 3%, respectively. Patients who did not receive CABG with RMA had a significantly lower 5‐year survival rate (45% vs. 63%, P = 0.049) and freedom from adverse events defined as mortality and/or admission for heart failure (19% vs. 43%, P < 0.001) than those who did. After adjustments for clinical covariates with inverse‐probability‐of‐treatment weighting, concomitant CABG was identified as an independent protective factor for adverse events (hazard ratio: 0.53; 95% confidence interval: 0.44–0.64; P < 0.001). Along with significant MR reduction, LV function parameters changed over time after surgery in both groups, with greater improvements in patients who underwent RMA with CABG (time effect, P < 0.001; and interaction effect, P = 0.002). Conclusions RMA can be performed with an acceptable operative mortality, irrespective of indications for CABG. Patients with ischaemic MR for whom CABG is indicated with RMA are more likely to show better long‐term and event‐free survival and greater improvements in LV systolic function. The optimal revascularization strategy should be discussed with a heart team whenever indicated in patients with ischaemic MR; otherwise, they may miss the opportunity to benefit from concomitant CABG during subsequent RMA.
