Abstract
INTRODUCTION Although extracorporeal membrane oxygenation (ECMO) is a well-established treatment for supporting severe cardiopulmonary failure, the morbidity and mortality of patients requiring ECMO support remain high. Evaluating and correcting potential risk factors associated with any ECMO-related complications may improve care and decrease mortality. This study aimed to assess the predictors of ECMO-related vascular and cerebrovascular complications among adult patients and to test the hypothesis that ECMO-related complications are associated with higher in-hospital mortality rates. METHODS This single-center, retrospective study included 856 ECMO runs administered via cannulation of the femoral vessels of 769 patients: venoarterial (VA) ECMO (n = 709, 82.8%) and venovenous (VV) ECMO (n = 147, 17.2%). The study outcomes included the occurrence of ECMO-related vascular and cerebrovascular complications and in-hospital death. The association of ECMO-related complications with the risk of in-hospital death was analyzed. RESULTS The incidences of ECMO-related vascular and cerebrovascular complications were 20.2% and 13.6%, respectively. The overall in-hospital mortality rate was 48.7%: 52.8% among VA ECMO runs and 29.3% among VV ECMO runs. Multivariable analysis indicated that age (P < 0.01), cardiopulmonary cerebral resuscitation (P < 0.01), continuous renal replacement therapy (P < 0.01), and initial platelet count [<50×103/μL (P = 0.02) and 50-100(×103)/μL (P < 0.01)] were associated with an increased risk of in-hospital death. ECMO-related vascular and cerebrovascular complications were not independently associated with higher in-hospital mortality rates for VA or VV ECMO runs. CONCLUSION ECMO-related vascular and cerebrovascular complications were not associated with an increased risk of in-hospital death among adult patients.

Abstract
Hypertrophic cardiomyopathy (HCM) is a genetic myocardial disease characterized by abnormal thickening of the myocardium caused by myocardial disarray and interstitial fibrosis. HCM is associated with sudden cardiac-related events, such as ventricular fibrillation, tachycardia, and syncope. Moreover, left ventricular or midcavity obstruction due to the thickened myocardium can result in severe heart failure and mortality in patients with HCM. Surgical myectomy is a standard treatment option for patients with symptomatic obstructive HCM; however, it is a complex procedure that requires careful planning and execution to avoid complications, such as residual flow obstruction, persistent obliteration of the left ventricular cavity in systole, or iatrogenic ventricular septal defects. Therefore, a thorough understanding of the mechanics of HCM and precise evaluation of the location and extent of the hypertrophic myocardium to be removed are crucial for preoperative planning. Multiphase cardiac CT postprocessing is important for preoperative evaluation and planning of surgical myectomy in patients with HCM. In this review, the authors highlight use of multiphase cardiac CT with step-by-step postprocessing methods to simulate successful surgical myectomy. The transaortic surgeon's view on end-diastolic phase images accurately represents the surgical field. Moreover, myocardial segmentation can be used to generate volume-rendered images and three-dimensional printing. CT evaluation can also assist in identifying concurrent abnormalities, such as mitral valve or papillary muscle abnormalities. In addition to CT, other imaging modalities for preoperative evaluation of HCM and postmyectomy evaluation methods are presented. ©RSNA, 2023 Test Your Knowledge questions in the supplemental material and the slide presentation from the RSNA Annual Meeting are available for this article.

Abstract
Metal-ligand binding plays a crucial role in regulating the photophysical properties of supramolecular gels. In this study, we designed 1-Pt complexes comprising a central benzene-1,3,5-tricarboxamide unit functionalized with three terpyridines, which can form supramolecular gels with Pt(II). The resulting supramolecular gel of 1-Pt exhibited strong orange emission, which was attributed to the metal-to-metal ligand charge transfer during gel formation. Furthermore, the temperature-dependent absorption spectrum changes of the supramolecular polymer 1-Pt exhibited a nonsigmoidal transition, following a cooperative pathway involving a nucleation-elongation mechanism. Additionally, the strategy for the co-assembling system involving 1-Pt with chiral molecules (D-form and L-form) induced the helical arrangement of 1-Ptvia chiral additives in supramolecular metallogels.

Abstract
Chiral metal-organic frameworks (CMOFs) and solid-state [2 + 2] photocyclization have been explored as independent areas in crystal engineering. We herein report the photoreactive CMOFs that undergo a [2 + 2] photocycloaddition reaction for the first time. Through the incorporation of a dipyridyl olefin ligand, 1,4-bis[2-(4-pyridyl)ethenyl]benzene, and d-camphoric acid or l-camphoric acid, we constructed a pair of homochiral Zn(II) CMOFs (d-1 or l-1) with a two-dimensional sql topology via a two-step procedure to avoid racemization. Both d-1 and l-1 were photoinert due to the large olefin bond separation. The removal of the solvent molecules between layers enabled them (d-1a and l-1a) to undergo [2 + 2] cycloaddition reactions; d-1a is more reactive (70%) than l-1a (20%) probably due to proper desolvation-induced rearrangement. The photoluminescence properties are also discussed. This work presents a new perspective on photoreactive homochiral network materials with diverse topologies and applications.

Abstract
BACKGROUND Cardiac allograft vasculopathy (CAV) is a major obstacle limiting long-term graft survival. Effective noninvasive surveillance modalities reflecting both coronary artery and microvascular components of CAV are needed. OBJECTIVES The authors evaluated the diagnostic performance of dynamic computed tomography-myocardial perfusion imaging (CT-MPI) and coronary computed tomography angiography (CCTA) for CAV. METHODS A total of 63 heart transplantation patients underwent combined CT-MPI and CCTA plus invasive coronary angiography (ICA) with intravascular ultrasonography (IVUS) between December 2018 and October 2021. The median interval between CT-MPI and heart transplantation was 4.3 years. Peak myocardial blood flow (MBF) of the whole myocardium (MBFglobal) and minimum MBF (MBFmin) among the 16 segments according to the American Heart Association model, except the left ventricular apex, were calculated from CT-MPI. CCTA was assessed qualitatively, and the degree of coronary artery stenosis was recorded. CAV was diagnosed based on both ICA (ISHLT criteria) and IVUS. Patients were followed up for a median time of 2.3 years after CT-MPI and a median time of 5.7 years after transplantation. RESULTS Among the 63 recipients, 35 (55.6%) had diagnoses of CAV. The median MBFglobal and MBFmin were significantly lower in patients with CAV (128.7 vs 150.4 mL/100 mL/min; P = 0.014; and 96.9 vs 122.8 mL/100 mL/min; P < 0.001, respectively). The combined use of coronary artery stenosis on CCTA and MBFmin showed the highest diagnostic performance with an area under the curve of 0.886 (sensitivity: 74.3%, specificity: 96.4%, positive predictive value: 96.3%, and negative predictive value: 75.0%). CONCLUSIONS The combination of CT-MPI and CCTA demonstrated excellent diagnostic performance for the detection of CAV. One-stop evaluation of the coronary artery and microvascular components involved in CAV using combined CCTA and CT-MPI may be a potent noninvasive screening method for early detection of CAV.

Abstract
Myocardial viability test to guide revascularization remains uncertain in patients with ischemic cardiomyopathy. We evaluated the different impacts of revascularization on cardiac mortality according to the extent of myocardial scar assessed by cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) in patients with ischemic cardiomyopathy. A total of 404 consecutive patients with significant coronary artery disease and an ejection fraction ≤35% were assessed by LGE-CMR before revascularization. Of them, 306 patients underwent revascularization and 98 patients received medical treatment alone. The primary outcome was cardiac death. During a median follow-up of 6.3 years, cardiac death occurred in 158 patients (39.1%). Revascularization was associated with a significantly lower risk of cardiac death than medical treatment alone in the overall population (adjusted hazard ratio [aHR] 0.29, 95% confidence interval (CI) 0.19 to 0.45, p <0.001). There was a significant interaction between the number of segments with >75% transmural LGE and revascularization on the risk of cardiac death (p = 0.037 for interaction). In patients with limited myocardial scar (<6 segments with >75% transmural LGE, n = 354), revascularization had a significantly lower risk of cardiac death than medical treatment alone (aHR 0.24, 95% CI 0.15 to 0.37, p <0.001); in patients with extensive myocardial scar (≥6 segments with >75% transmural LGE, n = 50), there was no significant difference between revascularization and medical treatment alone regarding the risk of cardiac death (aHR 1.33, 95% CI 0.46 to 3.80, p = 0.60). In conclusion, the assessment of myocardial scar by LGE-CMR may be helpful in the decision-making process for revascularization in patients with ischemic cardiomyopathy.

Abstract
We report the unique synthesis of chiral supramolecular tri- and penta-BCPs with controllable chirality using kinetically adjusted seeded supramolecular copolymerization in THF and DMSO (99:1, v/v). Tetraphenylethylene (D- and L-TPE) derivatives bearing D- and L-alanine side chains formed thermodynamically favored chiral products via a kinetically trapped in monomeric state with a long lag phase. In contrast, achiral TPE-G containing glycine moieties did not form a supramolecular polymer owing to the energy barrier in its kinetically trapped state. We show that the copolymerization of the metastable states of TPE-G not only enables the generation of supramolecular BCPs by the seeded living growth method, but also transfers chirality at the seed ends. This research demonstrates the generation of chiral supramolecular tri- and penta-BCPs with B-A-B, A-B-A-B-A, and C-B-A-B-C block patterns accompanying chirality transfer via seeded living polymerization.

Abstract
We report an inspiring case of a 55-year-old Korean female diagnosed with coronavirus disease 2019 (COVID-19)-associated acute respiratory distress syndrome (ARDS) in Mexico. The patient was assessed for lung transplant as a salvage therapy for treatment-refractory ARDS following no signs of clinical improvement for > 7 weeks, despite best treatment. The patient was transported from Mexico to Korea by air ambulance under venovenous extracorporeal membrane oxygenation (ECMO) support. She was successfully bridged to lung transplant on day 88, 49 days after the initiation of ECMO support. ECMO was successfully weaned at the end of operation, and no bleeding or primary graft dysfunction was observed within the first 72 hours. The patient was liberated from mechanical ventilation on postoperative day 9 and transferred to the general ward 5 days later. Despite the high doses of immunosuppressants, there was no evidence of viral reactivation after transplant. At 3 months post-transplantation, she was discharged to home without complication. Our experience suggests that successful lung transplant for COVID-19-associated ARDS is feasible even in a patient with prolonged pre-transplant ECMO support. Lung transplant may be considered a salvage therapy for COVID-19-associated ARDS that does not respond to conventional treatments.

Abstract
OBJECTIVE To investigate the prognostic value of preoperative cardiac magnetic resonance imaging (MRI) for long-term major adverse cardiac and cerebrovascular events (MACCEs) in patients undergoing tricuspid valve (TV) surgery for functional tricuspid regurgitation (TR). MATERIALS AND METHODS The preoperative cardiac MR images, New York Heart Association functional class, comorbidities, and clinical events of 78 patients (median [interquartile range], 59 [51-66.3] years, 28.2% male) who underwent TV surgery for functional TR were comprehensively reviewed. Cox proportional hazards analyses were performed to assess the associations of clinical and imaging parameters with MACCEs and all-cause mortality. RESULTS For the median follow-up duration of 5.4 years (interquartile range, 1.2-6.6), MACCEs and all-cause mortality were 51.3% and 23.1%, respectively. The right ventricular (RV) end-systolic volume index (ESVI) and the systolic RV mass index (RVMI) were higher in patients with MACCEs than those without them (77 vs. 68 mL/m², p = 0.048; 23.5 vs. 18.0%, p = 0.011, respectively). A high RV ESVI was associated with all-cause mortality (hazard ratio [HR] per value of 10 higher ESVI = 1.10, p = 0.03). A high RVMI was also associated with all-cause mortality (HR per increase of 5 mL/m² RVMI = 1.75, p < 0.001). After adjusting for age and sex, only RVMI remained a significant predictor of MACCEs and all-cause mortality (p < 0.05 for both). After adjusting for multiple clinical variables, RVMI remained significantly associated with all-cause mortality (p = 0.005). CONCLUSION RVMI measured on preoperative cardiac MRI was an independent predictor of long-term outcomes in patients who underwent TV surgery for functional TR.

Abstract
Objective We implemented a novel resectable myocardial model for mock myectomy using a hybrid method of three-dimensional (3D) printing and silicone molding for patients with apical hypertrophic cardiomyopathy (ApHCM). Materials and Methods From January 2019 through May 2020, 3D models from three patients with ApHCM were generated using the end-diastolic cardiac CT phase image. After computer-aided designing of measures to prevent structural deformation during silicone injection into molding, 3D printing was performed to reproduce anatomic details and molds for the left ventricular (LV) myocardial mass. We compared the myocardial thickness of each cardiac segment and the LV myocardial mass and cavity volumes between the myocardial model images and cardiac CT images. The surgeon performed mock surgery, and we compared the volume and weight of the resected silicone and myocardium. Results During the mock surgery, the surgeon could determine an ideal site for the incision and the optimal extent of myocardial resection. The mean differences in the measured myocardial thickness of the model (0.3, 1.0, 6.9, and 7.3 mm in the basal, midventricular, apical segments, and apex, respectively) and volume of the LV myocardial mass and chamber (36.9 mL and 14.8 mL, 2.9 mL and −9.4 mL, and 6.0 mL and −3.0 mL in basal, mid-ventricular and apical segments, respectively) were consistent with cardiac CT. The volume and weight of the resected silicone were similar to those of the resected myocardium (6 mL [6.2 g] of silicone and 5 mL [5.3 g] of the myocardium in patient 2; 12 mL [12.5 g] of silicone and 11.2 mL [11.8 g] of the myocardium in patient 3). Conclusion Our 3D model created using hybrid 3D printing and silicone molding may be useful for determining the extent of surgery and planning surgery guided by a rehearsal platform for ApHCM.

Abstract
INTRODUCTION It has been established that thyroid-stimulating hormone (TSH) stimulates the growth and development of thyroid malignancy, and a higher serum TSH level is associated with the incidence of thyroid cancer and an advanced tumour stage. This study aimed to evaluate the association of preoperative subclinical hypothyroidism with the prognosis of papillary thyroid cancer (PTC). METHODS A total of 466 patients who underwent surgery for PTC between December 2006 and June 2009 were enrolled. Among them, 44 patients had subclinical hypothyroidism, while 422 did not have subclinical hypothyroidism, as diagnosed using the preoperative thyroid function test. We compared the recurrence rate and association with clinicopathological features in the two groups. RESULTS The median patient age was 46.9 years (17-74 years). There were 420 female and 46 male patients. The median follow-up duration was 81.4 months. There were no statistical differences between the two groups with respect to age, sex, tumour size, extrathyroidal extension, multifocality, lymph node metastasis, TNM stages, recurrence and disease-free survival, despite a significant difference in the average TSH concentrations of the two groups. CONCLUSIONS Our results suggest that preoperative subclinical hypothyroidism was not associated with tumour aggressiveness and recurrence in PTC.

Abstract
INTRODUCTION The pelvic floor muscle (PFM) could affect female sexual functions. The hip muscles are morphologically and functionally linked to PFM and are important elements of female sexual attraction. AIM To determine the relationship between female sexual function and hip muscle strength and PFM functions in women with stress urinary incontinence (SUI). METHODS A total of 42 women with SUI were recruited in this study. Female sexual function was measured using the pelvic organ prolapse urinary incontinence sexual function questionnaire (PISQ). PFM functions were measured using a perineometer. Hip muscle strength was measured using a Smart KEMA tension sensor. The relationship between female sexual function and PFM function and hip muscle strength was assessed using Pearson correlation coefficients and multiple regression analyses with forward selection. MAIN OUTCOME MEASURES PISQ score, PFM functions (strength and endurance), and strength of hip extensor, abductor, and adductor were the main outcome measures. RESULTS For the behavioral/emotive domain in the PISQ, hip extensor strength (r = 0.452), PFM strength (r = 0.441), PFM endurance (r = 0.362), and hip adductor strength (r = 0.324) were significantly correlated and hip extensor strength emerged in multiple regression. For the physical domain in the PISQ, hip abductor strength (r = 0.417), PFM endurance (r = 0.356), hip adductor strength (r = 0.332), and PFM strength (r = 0.322) were significantly correlated and hip abductor strength entered in multiple regression. For partner-related domain in the PISQ, hip adductor (r = 0.386) and abductor strength (r = 0.314) were significantly correlated and hip adductor strength appeared in multiple regression. For the PISQ total score, hip extensor strength (r = 0.484), PFM endurance (r = 0.470), hip adductor strength (r = 0.424), hip abductor strength (r = 0.393), and PFM strength (r = 0.387) were significantly correlated and hip extensor strength and PFM endurance emerged in multiple regression. CONCLUSION The female sexual function could be related to not only PFM functions but also hip muscle strength in women with SUI. Hwang UJ, Lee MS, Jung SH, Ahn SH, Kwon OY.

Abstract
Background B-type natriuretic peptide (BNP) is a biomarker predicting morbidity and mortality in patients with congestive heart failure. However, the usefulness of pre- or postoperative BNP levels in patients undergoing cardiac surgery remains uncertain. We sought to determine the association of pre- or postoperative BNP levels on mortality in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB). Methods This study retrospectively evaluated 1,642 patients undergoing cardiac surgery under CPB over 2 years. The primary outcomes were 30-day and overall mortality after cardiac surgery. Results The 30-day mortality rate was 3.0% (n=49), and the overall mortality occurred in 118 patients during the mean follow-up period of 24.9±8.9 months. In multivariable analyses, preoperative BNP level was not significantly associated with 30-day [odds ratio (OR), 1.03; 95% confidence interval (CI), 0.99–1.06; P=0.06] or overall [hazard ratio (HR), 1.01; 95% CI, 0.98–1.03; P=0.50] mortalities. However, the postoperative BNP level was significantly associated with 30-day (OR, 1.05; 95% CI, 1.02–1.09; P=0.001) and overall (HR, 1.03; 95% CI, 1.01–1.04; P=0.01) mortalities. As a sensitivity analysis, postoperative BNP levels were divided into quartiles. The top quartile (≥484 pg/mL) was identified as a strong predictor of overall mortality (HR, 2.18; 95% CI, 1.14–4.19; P=0.02). Conclusions Preoperative BNP level was not associated with mortality after cardiac surgery. However, postoperative BNP level was associated with mortality after cardiac surgery, especially in patients with high levels (≥484 pg/mL). Further studies in larger cohorts are necessary to validate these results.

Abstract
In the present study, the patterns and clinical outcomes of prosthetic valve endocarditis (PVE) surgery were analyzed as compared with native valve endocarditis (NVE). The proportion of PVE among surgical infective endocarditis increased gradually through the study period. Patients with PVE was characterized by old age and more extensive infective lesions. PVE group showed notably higher early and overall mortality, and valve reinfection as well. PVE carried significant perioperative risks, and was an independent risk factor of overall mortality. Background and Objectives As a consequence of a growing number of patients undergoing prosthetic heart valve replacement, the incidence of prosthetic valve endocarditis (PVE) has increased. The study aims to analyze patterns and outcomes of PVE surgery as compared with native valve endocarditis (NVE). Methods We enrolled 269 patients (aged 58.0±15.7 years) who underwent valve surgery for infective endocarditis (IE) between 2013 and 2019. Of these, 56 had PVE whereas remainder (n=213) had NVE. Clinical outcomes were compared and multivariable analyses were conducted to determine risk factors for mortality. Results The proportion of PVE among surgical IE gradually increased from 15.4% (11/71) in the first time-quartile to 29.5% (18/61) in the last time-quartile (p=0.055). PVE patients were older, and more commonly had aorto-mitral curtain involvement and abscess formation than NVE group. Early mortality was 14.3% and 6.1% in PVE and NVE group, respectively (p=0.049). Postoperatively, PVE group had higher incidences of low cardiac output syndrome (p=0.027), new-onset dialysis (p=0.006) and reoperation for bleeding (p=0.004) compared to NVE group, but stroke rates were comparable (p=0.503). During follow-up (648.8 patient-years), PVE group showed significantly higher risks of overall mortality (p<0.001), valve reinfection (p<0.001) and permanent pacemaker implantation (p<0.001) than NVE group. On multivariable analysis, PVE (hazard ratio, 2.67; 95% confidence interval, 1.40–5.07; p=0.003) along with age, chronic kidney disease, multi-valve involvement, and causative organisms of Staphylococcus aureus or fungus were independent risk factors of overall mortality. Conclusions PVE carried significant perioperative risks, and was an independent risk factor of overall mortality.

Abstract
OBJECTIVES Although the incidence of patients with isolated tricuspid regurgitation (TR) is increasing, data regarding the clinical outcomes of isolated TR surgery are limited. This study sought to investigate the prognostic implications according to procedural types, and to identify preoperative predictors of clinical outcomes after isolated TR surgery. METHODS Among consecutive 2610 patients receiving tricuspid valve (TV) procedure, we analysed 238 patients (age, 59.6 years; 143 females) who underwent stand-alone TV surgery (repair, 132; replacement, 106) for severe TR. Primary outcome was the composite of all-cause mortality and heart transplantation. Clinical outcomes between the repair and the replacement groups were compared after adjusting with the inverse probability of treatment weighting (IPTW) method. RESULTS During follow-up (median, 4.1 years), 53 patients died and 4 received heart transplantation. Multivariable analysis revealed that age (p=0.001), haemoglobin level (p=0.003), total bilirubin (p=0.040), TR jet area (p=0.005) and right atrial (RA) pressure (p=0.022) were independent predictors of the primary outcome. After IPTW adjustment, there were no significant intergroup differences in the risk of primary outcome (HR 1.01; 95% CI 0.55 to 1.87). In the subgroup analysis, tricuspid annular diameter was identified as a significant effect modifier (p=0.012) in the comparison between repair versus replacement, showing a trend favouring replacement in patients with annular diameter >44 mm. CONCLUSIONS The outcomes of stand-alone severe TR surgery were independently associated with the severity of TR and RA pressure. In selected patients with severe annular dilation >44 mm, replacement may become a feasible option.

Abstract
AIMS To evaluate the acute and long-term prognosis of acute aortic syndrome (AAS) according to the disease entity [intramural haematoma (IMH) vs. aortic dissection (AD)] and the anatomical location (type A vs. B). METHODS AND RESULTS A total of 1012 patients [672 with AD and 340 with IMH (33.6%)] were enrolled between 1993 and 2015. Compared with AD patients, IMH patients were older and had higher frequency of female sex and distal aorta involvement. The overall crude in-hospital mortality of AAS was 8.6%; type A AD [15.0%; adjusted hazard ratio (aHR) 30.4; 95% confidence interval (CI) 8.62-107.3; P < 0.001], type A IMH (8.0%; aHR 4.85; 95% CI 1.29-18.2; P = 0.019), type B AD (5.0%; aHR 3.51; 95% CI 1.00-12.4; P = 0.051), and type B IMH [1.5%; aHR 1.00 (reference)]. During a median follow-up duration of 8.5 years (interquartile range: 4.0-13.5 years), AD (aHR 2.78; 95% CI 1.87-4.14; P < 0.001) and type A (aHR 2.28; 95% CI 1.45-3.58; P < 0.001) was associated with a higher risk of aortic death. After 90 days, a risk of aortic death was no longer associated with anatomical location (aHR 0.74; 95% CI 0.40-1.36; P = 0.33), but remained associated with disease entity (aHR 1.83; 95% CI 1.10-3.04; P = 0.02). CONCLUSION The clinical features, response to treatment strategy, and outcomes of IMH patients were distinct from those of AD patients. Both early and late survival was better for IMH than for AD. In addition to the anatomical location of AAS, the disease entity is an independent factor associated with both acute and long-term mortality in patients with AAS. Further investigation is necessary to confirm the prognostic implication of disease entity in different patient populations.

Abstract
Objective To identify the preoperative cardiac computed tomography (CT) factors influencing postoperative recurrent aortic regurgitation (AR) in patients who underwent aortic valve repair with the re-implantation technique (David operation) due to AR. Materials and Methods A total of 117 patients (age, 49.4 ± 15.6 years; 83 males) who underwent the David operation for AR were included in this retrospective study. Aortic root profiles including the aortic regurgitant orifice area (ARO) and the aortic cusp asymmetry ratio of the areas (ASRarea), which is defined as the maximum/minimum areas among the three cusp areas at the level of the commissures, were measured on preoperative cardiac CT scans. Clinical and CT findings were compared between a group with recurrent AR grade < 3 (no, trivial, or mild AR) and recurrent ≥ 3 + AR. To determine the optimal cut-off values of ASR and ARO, the receiver operating characteristic (ROC) curve was used. Cox regression analysis was used for the analysis of the factors affecting recurrent 3 + AR. Results Postoperatively, recurrent 3 + AR developed in 17 (14.5%) patients and occurred within a median of 268 days (interquartile range: 78–582 days). The cut-off ARO value for discriminating the patients with recurrent 3 + AR was > 24 mm2 (sensitivity, 76.5%; specificity 64.8%), and the area under the ROC curve (AUC) was 0.72. For ASRarea, the cut-off value was > 1.58 (sensitivity, 76.5%; specificity, 58.0%) and the AUC was 0.64. Multivariable Cox regression showed that ARO > 24 mm2 (hazard ratio = 3.79, p = 0.020) was a potential independent parameter for recurrent 3 + AR. ROC for the linear regression model showed that the AUC for both ARO and ASRarea was 0.73 (95% confidence interval, 0.64–0.81, p < 0.001). Conclusion ARO and ASRarea detected on preoperative cardiac CT would be potentially helpful for identifying AR patients who may benefit from the David operation.

Abstract
We demonstrated the exciplex emission of supramolecular polymers (Bipy-1) possessing bipyridine and pyrene moieties. The distinctive exciplex emission of the supramolecular polymers was controlled by tuning the molecular conformation in different composition ratios of a mixed DMSO/H2O solution. The strong exciplex emission of the supramolecular polymer I with yellow emission was a consequence of the intramolecular charge-transfer interactions in a mixed DMSO/H2O (60 : 40-1 : 99 v/v) solution.

Abstract
BACKGROUND Patients presenting with descending aortic aneurysms developing after aortic dissection often undergo continued aortic expansion which may require operative interventions to address the risk of aortic rupture. In light of the current advances in various treatment options, including endovascular approaches, we analyzed our experience with open surgical repair (OSR) of aneurysms of the descending aorta following aortic dissection. METHODS Patients who underwent open repair for aneurysmal changes of the descending aorta after chronic dissection were retrospectively studied. The 30-day operative mortality rate, midterm survival, and major complications were analyzed. Patients were divided into two categories; primary chronic type B aortic dissection and remnant repaired type A aortic dissection (RTAAD). RESULTS There were 149 patients with enlargement of the descending thoracic aorta developing after aortic dissection. Of these, 49 patients had medical management, while the remaining 100 patients received OSR. These patients were included in the present analysis. The 30-day mortality and permanent paraplegia rates were 9% and 4%, respectively. The 1-, 3-, and 5-year survival rates were 83%, 80.9%, and 76.1%, respectively. The 1- and 5-year survival rates between the primary chronic type B aortic dissection and remnant RTAAD groups showed no significant between-group differences at 86.7% and 84.3%, and 80% and 71.3%, respectively (P = .289). The overall outcomes of other complications such as renal injury, bleeding reoperation, and extracorporeal membrane oxygenation support showed no significant between-group differences, including an insignificantly higher neurologic complication rate in the remnant RTAAD group. The survival rate in patients with Marfan syndrome was significantly higher than in the patients without Marfan syndrome (P = .033). CONCLUSIONS OSR for descending aortic aneurysms developing after chronic aortic dissection showed good early and mid- to long-term outcomes, with acceptably low complication rates. OSR for descending aortic aneurysm after chronic aortic dissection associated with Marfan syndrome also showed good early and mid- to long-term outcomes.

Abstract
Two pyrene derivatives having the perylenediimide (1) or the alky chain (2) in the middle of molecules were synthesized. Co-assembled supramolecular gels were prepared at different molar ratios of 0.2, 0.5, and 0.8 equiv. of 2 to 1. By SEM observation, the morphology of co-assembled supramolecular gels changed from spherical nanoparticles to three-dimensional network nanofibers as the ratio of 2 increased. In addition, the pyrene-excimer emission of co-assembled gels increased with increasing concentration of 2, and was stronger when compared with the condition without 1 or 2, indicating the formation of pyrene interaction between 1 and 2. In addition, the sol-gel transition was found to be reversible over repeated measurement by tube inversion method. The rheological properties of co-assembled supramolecular gels were also improved by increasing the ratio of 2, due to the increased nanoscale flexibility of supramolecular packing by introducing alkyl chain groups through heterogeneous pyrene interaction. These findings suggest that macroscale mechanical strength of co-assembled supramolecular gel was strongly influenced by nanoscale flexibility of the supramolecular packing.

Abstract
OBJECTIVES This study aimed to evaluate the impact of left atrial appendage exclusion on clinical outcomes in patients with atrial fibrillation (AF) undergoing rheumatic mitral surgery. METHODS We retrospectively reviewed 1226 consecutive patients with AF (54.5±11.6 years; 68.2% females) who underwent rheumatic mitral valve (MV) surgery from 1997 to 2016. The left atrial appendage was preserved in 836 (68.2%) and excluded in 390 (31.8%) patients. Surgical AF ablation was performed in 506 (60.5%) and 304 (77.9%) patients with preserved and excluded left atrial appendage, respectively. For baseline adjustment, propensity matching was used. RESULTS During a median follow-up of 63.4 months (IQRs, 20-111 months), there were no significant intergroup differences in the risks of mortality (2.77% vs 3.03%/patient-years) and thromboembolic events (0.91% vs 1.02%/patient-years). In the 258 pairs of propensity-score matched patients, death (2.77% vs 3.03%/patient-years) and thromboembolism (1.36% vs 0.82%/patient-years) outcomes were comparable for both groups. In a subgroup undergoing ablation (n=810), there were no significant differences in the adjusted risks of death (HR, 0.67; 95% CI, 0.34 to 1.32) and thromboembolism (HR, 0.47; 95% CI, 0.18 to 1.26). In a subgroup not undergoing ablation (n=416), however, left atrial appendage preservation tended to have higher adjusted risks for death (HR, 2.24; 95% CI, 0.98 to 5.13) and thromboembolism (HR, 4.41; 95% CI, 0.97 to 20.1). CONCLUSIONS Left atrial appendage preservation did not seem to have greater risks of adverse clinical events in patients with AF undergoing rheumatic MV surgery particularly when ablation procedure is combined.

Abstract
We report kinetically controlled chiral supramolecular polymerization based on ligand-metal complex with a 3 : 2 (L : Ag+) stoichiometry accompanying a helical inversion in water. A new family of bipyridine-based ligands (d-L1, l-L1, d-L2, and d-L3) possessing hydrazine and d- or l-alanine moieties at the alkyl chain groups has been designed and synthesized. Interestingly, upon addition of AgNO3 (0.5-1.3 equiv.) to the d-L1 solution, it generated the aggregate I composed of the d-L1AgNO3 complex (d-L1 : Ag+ = 1 : 1) as the kinetic product with a spherical structure. Then, aggregate I (nanoparticle) was transformed into the aggregate II (supramolecular polymer) based on the (d-L1)3Ag2(NO3)2 complex as the thermodynamic product with a fiber structure, which led to the helical inversion from the left-handed (M-type) to the right-handed (P-type) helicity accompanying CD amplification. In contrast, the spherical aggregate I (nanoparticle) composed of the d-L1AgNO3 complex with the left-handed (M-type) helicity formed in the presence of 2.0 equiv. of AgNO3 and was not additionally changed, which indicated that it was the thermodynamic product. The chiral supramolecular polymer based on (d-L1)3Ag2(NO3)2 was produced via a nucleation-elongation mechanism with a cooperative pathway. In thermodynamic study, the standard ΔG° and ΔH e values for the aggregates I and II were calculated using the van't Hoff plot. The enhanced ΔG° value of the aggregate II compared to that of the formation of aggregate I confirms that aggregate II was thermodynamically more stable. In the kinetic study, the influence of concentration of AgNO3 confirmed the initial formation of the aggregate I (nanoparticle), which then evolved to the aggregate II (supramolecular polymer). Thus, the concentration of the (d-L1)3Ag2(NO3)2 complex in the initial state plays a critical role in generating aggregate II (supramolecular polymer). In particular, NO3 - acts as a critical linker and accelerator in the transformation from the aggregate I to the aggregate II. This is the first example of a system for a kinetically controlled chiral supramolecular polymer that is formed via multiple steps with coordination structural change.

Abstract
Background and Objectives This second adult heart transplantation (HTx) report is based on Korean Organ Transplant Registry data submitted on 400 HTxs in recipients of all ages. Methods From March 2014 to December 2017, a total of 400 HTxs were performed at 4 major centers in Korea. We analyzed demographics and characteristics according to transplant years. Patterns of immunosuppression, allograft rejection, and survival after HTx were analyzed. Donor and recipient age were highlighted. Results Some distinct differences in HTx statistics were noted. Mean donor age increased significantly in the most recent years compared to 2014–2015, while mean recipient age did not change. The proportion of patients on pre-transplant extracorporeal membrane oxygenation (ECMO) increased over time. One-year and intermediate-term survival was significantly worse in patients on pre-transplant ECMO compared to those without mechanical support. Over the years, tacrolimus has increased to become the most frequently used calcineurin inhibitor over cyclosporine, while the number of patients using steroids both at discharge and 1-year follow-up has declined. Age did not affect 1-year survival, but significantly affected intermediate-term survival. Conclusions From 2014 to 2017, centers were willing to accept older donors to address increasing organ shortages and more patients received transplant under ECMO care. Increasing age was a strong independent factor for intermediate-term survival, however, post-transplant comorbidities did not differ among age groups. Further studies with longer follow-up duration are needed to better understand age-related post-transplant prognosis.

Abstract
Background Recently, the number of lung transplants in South Korea has increased. However, the long-term outcome data is limited. In this study, we aimed to investigate the long-term outcomes of adult lung transplantation recipients. Methods Among the patients that underwent lung transplantation at a tertiary referral center in South Korea between 2008 and 2017, adults patient who underwent deceased-donor lung transplantation with available follow-up data were enrolled. Their medical records were retrospectively reviewed. Results Through eligibility screening, we identified 60 adult patients that underwent lung (n=51) or heart-lung transplantation (n=9) during the observation period. Idiopathic pulmonary fibrosis (46.7%, 28/60) was the most frequent cause of lung transplantation. For all the 60 patients, the median follow-up duration for post-transplantation was 2.6 years (range, 0.01–7.6). During the post-transplantation follow-up period, 19 patients (31.7%) died at a median duration of 194 days. The survival rates were 75.5%, 67.6%, and 61.8% at 1 year, 3 years, and 5 years, respectively. Out of the 60 patients, 8 (13.3%) were diagnosed with chronic lung allograft dysfunction (CLAD), after a mean duration of 3.3±2.8 years post-transplantation. The CLAD development rate was 0%, 17.7%, and 25.8% at 1 year, 3 years, and 5 years, respectively. The most common newly developed post-transplantation comorbidity was the chronic kidney disease (CKD; 54.0%), followed by diabetes mellitus (25.9%). Conclusion Among the adult lung transplantation recipients at a South Korea tertiary referral center, the long-term survival rates were favorable. The proportion of patients who developed CLAD was not substantial. CKD was the most common post-transplantation comorbidity.

Abstract
Background Fluid resuscitation is critical to perioperative maintenance of adequate preload and cardiac output after cardiac surgery. Liberal use of saline, however, is reportedly associated with an increased risk of acute kidney injury (AKI) in critically ill patients. This study examined the effects of high- versus low-volume saline administration on AKI after cardiac surgery. Methods In this retrospective study, we evaluated 1,740 consecutive patients who underwent cardiac surgery over a 2-year period. The patients were divided into high-volume saline (n=328, 18.8%) and low-volume saline (n=1,412, 81.2%) groups based on the amount of saline (>1 or ≤1 L, respectively) administered during the first 48 postoperative hours. Results AKI, the primary outcome, was defined according to the Risk, Injury, Failure, Loss, End Stage classification. There were no significant differences in the incidence of AKI (P=0.46), new renal replacement therapy (RRT) (P=0.39), and early mortality (P=0.52) between the 2 groups. Adjustment of baseline characteristics using propensity score matching showed that high-volume of saline administration was not significantly associated with an increased risk of AKI (OR, 1.22; 95% CI, 0.77-1.93; P=0.38), new RRT (OR, 1.25; 95% CI, 0.68-2.28; P=0.45), or early mortality (HR, 0.98; 95% CI, 0.48-2.02; P=0.97). These results were validated by further adjustments for significant covariates. Conclusions High-volume administration of saline in the period following cardiac surgery was not associated with a significant increase in the risk of AKI.

Abstract
This paper describes the peculiar co-assembly supramolecular polymerization behavior of triphenylamine trisamide derivatives with d-alanine (T-ala) or glycine (T-gly) moieties. Concentration and temperature-dependent circular dichroism (CD) spectroscopy revealed that the heating curves of co-assemblies obtained at various molar ratios of T-ala to T-gly exhibited two distinct transition temperatures. The first transition was due to the transformation from coiled helical bundles to single helical fibers without handedness. The second was due to a change from typical elongation to nucleation. These phenomena were confirmed by solvent-dependent decoiling of coiled helical structures and concentration-dependent morphological analysis. The two transitioning temperatures were dependent on the concentration of T-ala in the co-assemblies, suggesting that T-ala concentration plays an important role in the formation of coiled helical bundles. Our study demonstrated the first observation of two distinct transition temperatures in supramolecular polymers.

Abstract
An outbreak of a Megalocytivirus infection was found in the golden mandarin fish Siniperca scherzeri during September and October 2016, in Korea. Phylogeny and genetic diversity based on the major capsid protein (MCP) and adenosine triphosphatase (ATPase) genes showed a new strain. Designated as GMIV, this strain derived from the golden mandarin fish was suggested to belong to the red sea bream iridovirus (RSIV)-subgroup I. Additionally, this train clustered with the ehime-1 strain from red sea bream Pagrus major in Japan and was distinguished from circulating isolates (RSIV-type subgroup II and turbot reddish body iridovirus [TRBIV] type) in Korea. The infection level, evaluated by qPCR, ranged from 8.18 × 102 to 7.95 × 106 copies/mg of tissue individually, suggesting that the infected fish were in the disease-transmitting stage. The diseased fish showed degenerative changes associated with cytomegaly in the spleen as general sign of Megalocytivirus infection. The results confirm that the RSIV-type Megalocytivirus might have crossed the environmental and species barriers to cause widespread infection in freshwater fish.

Abstract
Background Cases of infective endocarditis (IE) require prompt etiological diagnosis for effective treatment. Molecular methods can aid in rapid and reliable diagnosis of culture-negative IE cases. We evaluated the utility of 16S rDNA PCR and sequencing in determining the causative agents of IE in valve tissues, especially when specimens were obtained after initiation of antimicrobial therapy. Methods We performed 16S rDNA PCR and sequencing in heart valve specimens and medical records review of 80 patients who underwent protocol-based cardiac surgery from 2013 to 2015. One patient did not meet the criteria for IE. Sixty-five (81.3%) and 14 pa-tients (17.5%) were diagnosed as having definite IE and possible IE, respectively. Blood and heart valve biopsy tissue were examined by using routine microbiological methods. Results Blood cultures in our hospital were IE-positive for 33 patients (41.8%), whereas 49 patients (62.0%) showed positive blood cultures when initial blood cultures performed at the referring hospital were included. Eighteen (22.8%) and 40 patients (50.6%) were IE-positive in valve tissue cultures and 16S rDNA PCR, respectively. Bacteria in the Streptococcus mitis group (n=26) were the most common etiological agents of IE. Eight (10.1%) culture-negative specimens tested positive by 16S rDNA PCR. In five of eight PCR-positive and culture-negative cases, fastidious or anaerobic organisms were the cause of IE. Conclusions Direct 16S rDNA PCR and sequencing can be used as a supplementary method to conventional blood and biopsy culture testing, especially in culture-negative IE cases that are negative for IE by culture.

Abstract
The development of specifically targeted nanoparticles for subcellular organelles modified with a low-molecular-weight organic compound as drug nanocarriers can bring about wide applications in cancer therapy. However, their utility has been hampered by low selectivity, poor biodistribution, and limited efficiency. Herein, we report the aggregation behavior of a triphenylphosphonium-appended coumarin probe (TPP-C) in an aqueous solution and its applications as a mitochondria-targeting probe, and drug delivery carrier, which is a rare example for a low molecular-weight organic compound. The TPP-C formed homogeneous nanoparticles with small diameters in water as well as in mixtures of organic solvents and water. In pure water, the homogeneous nanoparticles induced J-aggregation, whereas in mixed solvents, the homogeneous nanoparticles induced H-aggregation. The luminescence intensities of nanoparticles originated from the aggregation-induced emission (AIE) effect in pure water and also in mixtures of organic solvents and water. These findings indicate that the AIE effect of TPP-C was dependent on the solvent. More interestingly, the TPP-C nanoparticles selectively accumulated in mitochondria. The TPP-C nanoparticles alone exhibited noncytotoxicity toward cancer cells. However, with the encapsulation of the anticancer drug doxorubicin (DOX) into the TPP-C nanoparticles, the DOX was efficiently delivered to the mitochondria. These results indicated that the proposed system demonstrates promise as a platform for future clinical medication, particularly for specific suborganelle-targeted drug delivery systems for cancer therapy.

Abstract
BACKGROUND/AIMS The use of extracorporeal membrane oxygenation (ECMO) is spreading rapidly, with successful procedures reported in the ECMO for Severe Adult Respiratory failure (CESAR) trial and treatment of the H1N1 pandemic. However, ECMO is associated with a high mortality rate. This study aimed to show that increased experience and improved teamwork through education may reduce the mortality rate associated with ECMO. METHODS A retrospective study was performed. Data were collected from January 1, 2009, to December 31, 2011. The data were divided into two periods: 2009/2010 (period 1) and 2011 (period 2). The protocol and training program were applied during period 2. RESULTS Seventy-six patients were included. The most common disease requiring ECMO support was pneumonia (43.4%). ECMO was applied within 7 days in 76.3% of patients. The primary outcomes, such as Intensive Care Unit (ICU) and hospital mortality rates, were higher during period 1 (91.3%) than period 2 (66.7%, p = 0.013). A multivariate analysis revealed that ECMO weaning failure was the only factor associated with ICU and hospital mortality (ICU mortality: hazard ratio [HR], 11.349; 95% confidence interval [CI], 1.281 to 100.505; p = 0.029; hospital mortality: HR, 17.976; 95% CI, 2.263 to 142.777; p = 0.006). CONCLUSIONS The mortality rate associated with the ECMO procedure decreased following the ECMO training program. However, applying the training program to ECMO management is not an independent factor for the mortality rate. Further studies should be performed to help reduce the mortality rate associated with ECMO.

Abstract
BACKGROUND This study was conducted in order to compare the strength of scapular elevator and shoulder abductor with and without restricted scapular elevation between male subjects with and without myofascial trigger points in the upper trapezius. METHODS In total, 15 male subjects with myofascial trigger points, and 15age- and weight-matched male subjects without myofascial trigger points in the upper trapezius. Each subject was measured in the strength of maximum isometric scapular elevation and shoulder abduction with and without restricted scapular elevation. Maximum isometric contractions were measured using the Smart KEMA strength measurement system. Independent t-tests were used to compare shoulder strength values between the myofascial trigger points and non- myofascial trigger points groups. FINDING The results showed that shoulder abductor strength in the group with myofascial trigger points (5.64kgf) was significantly lower than in the group without myofascial trigger points (11.96kgf) when scapular elevation was restricted (p<0.05). However, there was no significant difference in the strength of the scapular elevator or shoulder abductor between groups (p>0.05). INTERPRETATION These findings suggest that decreased strength in the shoulder abductor with restricted scapular elevation should be considered in evaluating and treating individuals with myofascial trigger points of the upper trapezius.

Abstract
Although rare, postcardiac surgery nonocclusive mesenteric ischemia (NOMI) is a life-threatening condition. Identifying the risk factors for NOMI during immediate postoperative period may help early detection and intervention, which leads to improved clinical outcomes. The objective of this study was to identify the clinical features and risk factors of NOMI for prognosis identification after cardiac surgery, focusing on immediate postoperative parameters.Among 9445 patients who underwent cardiac surgery over a span of 9 years, 40 NOMI cases (0.4%) requiring surgical interventions were reviewed. Suspected NOMI was diagnosed by sigmoidoscopy or computed tomography. To identify the risk factors, a control group (case: control = 1:3 ratio) was randomly selected and compared using logistic regression models.NOMI was diagnosed after a mean of 8.1 ± 9.6 days following cardiac surgery. Age (odds ratio: 1.16, 95% confidence interval: 1.08-1.25, P < .001), total vasoactive-inotropic score (VIS), and the maximal lactate level at postoperative day 0 (1.003, [1.001-1.005], P = .012), (1.23, [1.04-1.44], P = .011) were shown as risk factors. NOMI cases showed persistent hyperlactatemia without washout during the first 48 hours (P = .04). Thirty-four cases underwent exploratory laparotomy within a median of 10 (2-356) hours after the diagnosis, but only 17 patients (42.5%) survived. Compared with survivors, nonsurvivors showed higher total VIS at diagnosis, higher lactate levels during the first 24 hours postoperatively, and more frequently required extensive bowel resection (P < .05).Old age, postoperative high-dose vasoactive-inotropic use, and persistent high lactate level during the first 24 hours postsurgery were identified as risk factors for NOMI. Lactic acidosis and necrotic-bowel extent at surgical exploration were associated with poor survival.
