Watch-and-wait strategy for selected patients with type A intramural hematoma. Gen Thorac Cardiovasc Surg 2024; 72:225-231. [PMID: 37592167 DOI: 10.1007/s11748-023-01967-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 08/03/2023] [Indexed: 08/19/2023]
Abstract
OBJECTIVE This single-center retrospective study evaluated early and midterm outcomes of 100 consecutive patients with type A intramural hematoma. METHODS Initial watch-and-wait strategy was indicated if the maximum aortic diameter was < 50 mm, pain score was < 3/10 on the numerical rating scale, and no ulcer-like projection was observed in the ascending aorta. The primary endpoints of this study were all-cause and aorta-related deaths, and the secondary endpoint was aortic events. RESULTS Initial watch-and-wait strategy was indicated in 52 patients. Emergency aortic repair was indicated in the remaining 48 patients; 2, 31, and 15 patients died before surgery, underwent emergency surgery, and declined emergency surgery, respectively. Among the watch-and-wait group, 11 (21%) patients underwent aortic repair during hospitalization. In-hospital mortality rates, 5-year survival rates, and 5-year freedom from aorta-related death were not significantly different between the initial watch-and-wait strategy and emergency surgery (2% vs. 6%, 92% vs. 82%, and 100% vs. 94%, respectively). In the initial watch-and-wait strategy group, 5-year freedom from aortic events and freedom from aortic events involving the ascending aorta were 60% and 66%, respectively. CONCLUSIONS The early and midterm outcomes with the initial watch-and-wait strategy in patients with type A intramural hematoma with a maximum aortic diameter of ≤ 50 mm, pain score of ≤ 3/10, and no ulcer-like projection in the ascending aorta were favorable with no aorta-related death.

Predictive role of regional thigh tissue oxygen saturation monitoring during cardiopulmonary bypass in lung injury after cardiac surgery. J Artif Organs 2024:10.1007/s10047-024-01438-y. [PMID: 38498214 DOI: 10.1007/s10047-024-01438-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Accepted: 02/21/2024] [Indexed: 03/20/2024]
Abstract
Acute respiratory distress syndrome (ARDS) is a serious complication following cardiac surgery mainly associated with the use of cardiopulmonary bypass (CPB), which could increase the risk of mortality and morbidity. This study investigated the association of regional oxygen saturation (rSO2) during CPB with postoperative outcomes, including respiratory function. Patients who underwent cardiac surgery with CPB from 2015 to 2019 were included. Near-infrared spectroscopy was used to monitor rSO2 at the forehead, abdomen, and thighs throughout the surgery. Postoperative markers associated with CPB were assessed for correlations with PaO2/FiO2 (P/F) ratios at intensive care unit (ICU) admission. Postoperative lung injury (LI) was defined as moderate or severe ARDS based on the Berlin criteria, and its incidence was 29.9% (20/67). On multiple regression analysis, the following were associated with P/F ratios at ICU admission: vasoactive-inotropic scores at CPB induction (P = 0.03), thigh rSO2 values during CPB (P = 0.04), and body surface area (P < 0.001). A thigh rSO2 of 71% during CPB was significantly predictive of postoperative LI with an area under the curve of 0.71 (P = 0.03), sensitivity of 0.70, and specificity of 0.68. Patients with postoperative LI had longer ventilation time and ICU stays. Thigh rSO2 values during CPB were a potential predictor of postoperative pulmonary outcomes.

Abstract
OBJECTIVE This study focused on routine computed tomography imaging for aortic disease management and evaluated the trajectory of skeletal muscle changes through inpatient and outpatient cardiac rehabilitation. DESIGN Prospective observational study included patients who underwent abdominal computed tomography three times (baseline, postacute care, and follow-up). The area and density of the all-abdominal and erector spine muscles and intramuscular adipose tissue were measured. A generalized linear model with patients as random effects was used to investigate skeletal muscle changes. RESULTS Thirty-nine patients completed outpatient cardiac rehabilitation, and 60 were incomplete. Skeletal muscle area significantly decreased from baseline to the follow-up period only in the incomplete rehabilitation group. Skeletal muscle density significantly decreased from baseline to postacute care and increased at the follow-up period, but only patients who completed rehabilitation showed recovery up to baseline at the follow-up period. These trajectories were more pronounced in the erector spine muscle. Intramuscular adipose tissue showed a trend of gradual increase, but only the incomplete rehabilitation group showed a significant difference from baseline to the follow-up period. CONCLUSIONS The density of skeletal muscle may reflect the most common clinical course; skeletal muscle area and intramuscular adipose tissue are unlikely to improve positively, and their maintenance seemed optimal.

Initial thickness of the crescent may not be a reliable predictor of complications in type A intramural haematoma. Eur J Cardiothorac Surg 2024; 65:ezae006. [PMID: 38212990 DOI: 10.1093/ejcts/ezae006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 12/11/2023] [Accepted: 01/09/2024] [Indexed: 01/13/2024] Open
Abstract
OBJECTIVES This study aimed to investigate changes in haematoma thickness during the early period and their association with disease progression in patients who received initial medical treatment for type A intramural haematoma (IMH). METHODS Medical records and serial computed tomography angiography (CTA) images of patients who did not undergo emergency aortic repair for type A IMH upon presentation were retrospectively reviewed. The haematoma remodelling rate was determined using the following equation: thickness of the haematoma on the first CTA (mm) - thickness of the haematoma on the second CTA (mm)time between the first and second CTAs (h). RESULTS Among the 40 patients included in this study, 38 were indicated for initial watch-and-wait strategy, whereas 2 were indicated for emergency aortic repair but declined it. During hospitalization, 10 patients developed disease progression, with 2 in-hospital mortality cases. Analysis of the haematoma remodelling rate in 39 patients revealed that such a rate was significantly associated with the reciprocal of the time from onset. Analysis of all 70 CTA examinations performed within 24 h after the onset of IMH showed that haematoma thickness was significantly associated with the logarithm of the time from onset. Initial regression of the haematoma was not necessarily associated with avoidance of disease progression. CONCLUSIONS In type A IMH, the thickness of the haematoma in the ascending aorta tended to decrease in the very early period; however, prompt regression of the haematoma was not necessarily associated with avoidance of disease progression.

Recurrent left ventricular thrombus due to essential thrombocythemia complicated by COVID-19. J Cardiol Cases 2024; 29:15-18. [PMID: 38188321 PMCID: PMC10770075 DOI: 10.1016/j.jccase.2023.09.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 07/18/2023] [Accepted: 09/05/2023] [Indexed: 01/09/2024] Open
Abstract
Essential thrombocythemia is a risk factor for thrombosis and hemorrhage. During the perioperative period of cardiac surgery, the risk of thrombosis and hemorrhage increases. Coronavirus disease 2019 (COVID-19) is also associated with thrombosis. We present the case of a 69-year-old man with essential thrombocythemia complicated by COVID-19 who developed a left ventricular thrombus. We performed thrombectomy, but the patient developed recurrent left ventricular thrombus 8 days after surgery. Emergency redo thrombectomy was performed followed by aggressive blood-thinning therapy. The postoperative course was complicated by cardiac tamponade requiring surgical drainage 8 days after the second surgery. The patient was discharged home 25 days after the second operation without any complications. Learning objective Left ventricular thrombus is a rare but fatal complication associated with essential thrombocythemia. COVID-19 has also been reported to cause coagulopathy. This case suggested that after surgery for left ventricular thrombus complicated by multiple risk factors including essential thrombocythemia and COVID-19, aggressive blood-thinning therapy with combination of anticoagulation, antiplatelet, and metabolic antagonist may help prevent recurrent thrombosis.

Trends and Outcomes of Early Rehabilitation in the Intensive Care Unit for Patients With Cardiovascular Disease: A Cohort Study With Propensity Score-Matched Analysis. Heart Lung Circ 2023; 32:1240-1249. [PMID: 37634967 DOI: 10.1016/j.hlc.2023.05.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 05/21/2023] [Accepted: 05/24/2023] [Indexed: 08/29/2023]
Abstract
BACKGROUND The effectiveness of acute-phase cardiovascular rehabilitation (CR) in intensive care settings remains unclear in patients with cardiovascular disease (CVD). This study aimed to investigate the trends and outcomes of acute-phase CR in the intensive care unit (ICU) for patients with CVD, including in-hospital and long-term clinical outcomes. METHOD This retrospective cohort study reviewed a total of 1,948 consecutive patients who were admitted to a tertiary academic ICU for CVD treatment and underwent CR during hospitalisation. The endpoints of this study were the following: in-hospital outcomes: probabilities of walking independence and returning home; and long-term outcomes: clinical events 5 years following hospital discharge, including all-cause readmission or cardiovascular events. It evaluated the associations of CR implementation during ICU treatment (ICU-CR) with in-hospital and long-term outcomes using propensity score-matched analysis. RESULTS Among the participants, 1,092 received ICU-CR, the rate of which tended to increase with year trend (p for trend <0.001). After propensity score matching, 758 patients were included for analysis (pairs of n=379 ICU-CR and non-ICU-CR). ICU-CR was significantly associated with higher probabilities of walking independence (rate ratio, 2.04; 95% CI 1.77-2.36) and returning home (rate ratio, 1.22; 95% CI 1.05-1.41). These associations were consistently observed in subgroups aged >65 years, after surgery, emergency, and prolonged ICU stay. ICU-CR showed significantly lower incidences of all-cause (HR 0.71; 95% CI 0.56-0.89) and cardiovascular events (HR 0.69; 95% CI 0.50-0.95) than non-ICU-CR. CONCLUSIONS The implementation of acute-phase CR in ICU increased with year trend, and is considered beneficial to improving in-hospital and long-term outcomes in patients with CVD and various subgroups.

Abstract
Objectives: Since 2018, we have routinely placed an Amplatzer vascular plug (AVP) in the proximal left subclavian artery (LSCA) to prevent embolic events during thoracic endovascular aortic repair with arch vessel debranching (d-TEVAR). Type II endoleaks of LSCA origin were observed in two patients (20%), and the coil-in-plug (CIP) method, i.e., microcatheter insertion through the plug and addition of coil embolization, which has been used since August 2019, was performed. This study aims to evaluate the effectiveness of the CIP method for LSCA embolization. Methods: A total of 26 patients who underwent d-TEVAR for an aortic arch aneurysm between 2018 and 2022 were retrospectively reviewed. Ten patients who underwent d-TEVAR with a simple AVP placement (the control group) and 16 patients who underwent d-TEVAR with the CIP method (the CIP group) were compared. Results: Two patients had type II endoleaks in the control group, whereas none had them in the CIP group. LSCA length was significantly shorter in patients with endoleaks than in those without endoleaks (24.5 vs. 50.3 mm; p<0.01). No perioperative deaths or cerebral infarctions occurred in either group. Conclusions: AVP placement in the LSCA during d-TEVAR effectively prevented perioperative cerebral infarction. d-TEVAR with CIP was especially useful in patients with a short LSCA.

Abstract
OBJECTIVE In surgery for active infective endocarditis (aIE), it is often difficult to achieve balance between thorough debridement and preservation of native valve. This study aimed to evaluate the validity of our native valve preservation techniques including leaflet peeling and autologous pericardial reconstruction. METHODS From January 2012 to December 2021, 41 consecutive patients underwent mitral valve surgery for aIE. Twenty-four patients who underwent mitral valve plasty (group P) and 17 patients who underwent mitral valve replacement (group R) were retrospectively compared regarding early and long-term outcomes. RESULTS Patients in the group P were significantly younger and had fewer preoperative shock, congestive heart failure and cerebral embolism. There was 18% in-hospital mortality in the group R, but none in the group P. In the group P, one patient underwent valve replacement for recurrence of mitral regurgitation 3-years after surgery, and 5-year freedom from mitral reoperation was 93%. CONCLUSIONS Techniques of leaflet peeling and autologous pericardial reconstruction improved the feasibility of mitral valve plasty for aIE, and the early and long-term outcomes were favorable.

Abstract
BACKGROUND Blunt thoracic aortic injury is one of the most lethal traumatic injuries. Ruptured cases often result in cardiac arrest before arrival at the hospital, and survival is rare. CASE PRESENTATION A female patient in her 30 s was struck by an automobile while she was walking across an intersection. She was in a state of shock when emergency services arrived and was in cardiac arrest shortly after arriving at the hospital. A left anterolateral thoracotomy revealed a massive hemothorax secondary to thoracic aortic rupture. In addition, the patient had multiple traumas, including maxillary, pelvic, and lumbar burst fractures. We attempted to directly suture the aortic lesion; however, the increasing blood pressure caused the suture to break. We used a thoracic stent graft while ensuring permissive hypotension. Her postoperative prognosis was positive, and she was transferred to another hospital 85 days later. CONCLUSIONS We successfully performed a hybrid surgery combining thoracotomy and endovascular repair for this emergency case of blunt thoracic aortic injury with rupture.

Abstract
Abstract
Background
Early rehabilitation in the intensive care unit (ICU), including early mobility therapy, is known to improve the clinical outcomes in patients with critically ill. However, the effectiveness of acute-phase cardiovascular rehabilitation (CR) during ICU treatment have not been thoroughly evaluated in patients with cardiovascular disease (CVD).
Purpose
We aimed to investigate the trends and outcomes of acute-phase CR in the ICU for patients with CVD, including in-hospital and long-term clinical outcomes.
Methods
We reviewed 1948 consecutive patients with CVD admitted to tertiary academic ICU at a university hospital. Patients were arbitrarily assessed by an ICU team consisting of medical and surgical doctors, nurses and physiotherapists within 24 hours after admission to ICU to discover whether their rehabilitation could be initiated according to the specific clinical trial and statement. As clinical characteristics, disease aetiology, comorbid conditions, and ICU treatment were obtained from an electronic database. We evaluated the probability of return to walking independence and return to home as in-hospital clinical outcomes. All patients were followed for five years and investigated all-cause and cardiovascular events after hospital discharge as long-term clinical outcomes. The associations between the implementation of CR during ICU treatment (ICU-CR) and clinical outcomes were evaluated using propensity score-matched analysis with adjustment for clinical characteristics in all matched patients and various subgroups, including aged >65 years, surgical patients, emergency, and length of ICU stay ≥48 hours.
Results
Out of studied patients, 1092 patients received ICU-CR, the number of which positively correlated with year-trend (r=0.986, P<0.001). After propensity score matching with adjustment for clinical characteristics including calendar years, 758 patients were included for analysis (pairs of n=379 ICU-CR and non-ICU-CR). The ICU-CR was significantly associated with a higher probability of return to walking independence (incident rate ratio [IRR], 2.04; 95% confidence interval [CI], 1.77–2.36) and return to home (IRR, 1.22 95% CI, 1.05–1.41). These associations were consistently observed in various subgroups regarding CVD conditions (Figure 1). During the median follow-up periods of 2.6 years, all-cause clinical events and cardiovascular events occurred in 289 patients (38.1%) and 153 patients (20.2%), respectively. The ICU-CR showed significantly lower rates of five-year all-cause and cardiovascular events than non-ICU-CR (hazard ratio [95% CI] for all-cause events and cardiovascular events, 0.71 [0.56–0.89] and 0.69 [0.50–0.95], respectively, Figure 2).
Conclusions
The implementation of acute-phase CR in the ICU increased with year-trend, considered beneficial to improve in-hospital and long-term clinical outcomes in patients with CVD and various subgroups of relatively severe disease conditions.

Perme ICU Mobility Score as a comprehensive assessment tool of acute-phase rehabilitation is correlated with clinical outcomes in patients after cardiovascular surgery. Eur Heart J 2022.

Abstract
Abstract
Background
Early mobility therapy in the intensive care unit (ICU) is widely employed to improve the physical function and prognosis of patients with critically ill. On the other hand, patients who undergo cardiovascular surgery frequently suffer from disabilities after ICU care due to their cardiopulmonary conditions and treatments. However, few studies have reported the procedures and assessments of acute-phase rehabilitation in these patients. Recently, the Perme ICU Mobility Score (Perme Score) was developed as a reliable tool to assess comprehensive mobility status of patients in the ICU. We hypothesised that the Perme Score is a useful tool for assessing the mobility levels in the ICU and predicting clinical outcomes in patients undergoing acute-phase rehabilitation after cardiovascular surgery.
Purpose
To investigate the associations between the Perme Score within the second days after cardiovascular surgery and the patients' clinical outcomes, including physical function and the incidence of clinical events.
Methods
We studied 224 consecutive patients (34.4% female; aged 65±13 years) who were admitted to the ICU of a tertiary academic hospital after cardiac and/or major vascular surgery. Clinical characteristics including patient profiles, comorbidities, surgical details and APACHE II and SOFA scores were evaluated on ICU admission. The Perme Score contains categories on mental status, potential mobility barriers, muscle strength and mobility level, with higher scores indicating greater activity levels in the ICU. We assessed the Perme Score within the second days after the surgery. As a physical function at hospital discharge, we measured the six-minute walk distance (6MWD). The primary endpoint was a composite outcome of the number of all-cause mortality and/or all-cause unplanned readmission. We analysed the associations of the Perme Score with the 6MWD and the incidence of clinical events using multiple regression analysis and multivariate Poisson regression analysis, respectively.
Results
After adjusting for clinical confounding factors, a higher Perme Score was an independent factor of a higher 6MWD (Table 1). During the median follow-up period of 1.3 years, 51 cases of all-cause mortality/readmission occurred in 37 (16.5%) patients, with an incidence rate of 18.6/100 person-years. In the multivariate Poisson regression analysis, even after adjusting for the severity score in the ICU, a higher Perme Score was significantly and independently associated with lower rates of all-cause clinical events (adjusted incident rate ratio: 0.96, 95% confidence interval: 0.93–0.99, P=0.008, Figure 1).
Conclusions
The Perme Score within the second days after cardiovascular surgery is correlated with physical function at hospital discharge and the incidence of clinical events after discharge. Thus, a comprehensive assessment of acute-phase rehabilitation after cardiovascular surgery may be useful in predicting clinical outcomes.

Abstract
OBJECTIVES We applied high-flow regional cerebral perfusion (HFRCP) for aortic arch reconstruction in neonates and infants by monitoring regional oxygen saturation of the thigh (rSO2T) using near-infrared spectroscopy to maintain peripheral perfusion. This study was designed to investigate the optimal perfusion flow of HFRCP for renal protection. METHODS From 2009 to 2021, 28 consecutive neonates and infants who underwent aortic arch reconstruction with HFRCP were enrolled. The median age of the patients was 27 days; the median body weight was 3.0 kg. In HFRCP, perfusion flow was targeted at approximately 80-100 mL/kg/min and then lowered corresponding to brain rSO2 levels and blood gas data. Isosorbide dinitrate and chlorpromazine were administered to enhance peripheral perfusion flow. Regional oxygen saturation of the forehead and thighs were monitored. The stage of acute kidney injury (AKI) was classified based on the Kidney Disease Improving Global Outcomes criteria. RESULTS No patients had neurological events and peritoneal dialysis after surgery. The incidence of AKI was 39.3% with only three patients having greater than stage 2 AKI. The maximum postoperative serum creatinine concentration was negatively associated with the lowest rSO2T during HFRCP. The rSO2T during HFRCP was a predictive factor for postoperative creatinine increase of ≧0.3 mg/dL. The area under receiver operating characteristic curve was 0.78 with the cutoff value of 48% for rSO2T. CONCLUSIONS The rSO2T during HFRCP is a potential predictor of postoperative renal function. To prevent AKI, the rSO2T should be preserved more than 48% by increasing HFRCP flow.

Abstract
Initial 37 cases of robot-assisted cardiac surgery were reviewed. The early outcomes were favorable with low transfusion rate and no mortality, but some of the very early cases required reoperation after discharge. In our cohort, in terms of aortic cross-clamp time, the learning curve seemed to mature at shortly after the 30th case, but in view of the whole operation time, it did not plateau as of the 37th case.

Abstract
Abstract
Study question
To evaluate the effectiveness of chlormadinone acetate (CMA) for preventing premature LH surge in patients with normal ovarian reserve compared to cetrorelix.
Summary answer
In progestin-primed ovarian stimulation (PPOS) than GnRH antagonist (GnRH-ant), the incidence of premature LH surge was significantly lower, without significant difference in oocyte maturation rate.
What is known already
The GnRH-ant protocol is one of the conventional protocols which has some disadvantages including increased premature LH surge rate and cancelation rate. In recent years, the PPOS protocol has attracted attention as a new ovarian stimulation using progestin as an alternative to GnRH analog for suppressing a premature LH surge, however its efficacy is still controversial. In addition, many studies have investigated the reproductive outcomes of PPOS using medroxy-progesterone acetate or dydrogesterone; however, there are few reports of CMA, an oral progestin, which is inexpensive and widely used in Japan.
Study design, size, duration
This retrospective cohort study was performed in a reproduction center between March 2018 and October 2020 which included 977 Japanese patients with normal ovarian reserve undergoing PPOS with CMA (n = 299), or GnRH antagonist (GnRH-ant) with cetrorelix (n = 608) in their first IVF cycle at the reproduction center. In subgroup analysis, pregnancy outcomes after frozen embryo transfers (FET) between PPOS (n = 284) and GnRH-ant (n = 579) were also compared.
Participants/materials, setting, methods
The inclusion criteria were patients aged < 40 years and AMH ≧ 1.1 ng/mL, who underwent autologous oocyte retrieval in their first IVF cycle with freeze-all strategy. The primary outcome was the incidence of premature LH surge, the secondary outcomes was oocyte maturation rate. To reduce the impact of treatment bias and potential confounding factors, we conducted logistic regression models with inverse-probability-of-treatment weighting (IPTW).
Main results and the role of chance
After IPTW, baseline clinical data were well-balanced between the two groups, including age, AMH, BMI, the duration, type, and cause of infertility, antral follicle count, the history of recurrent spontaneous abortion, and previous IVF attempts. The premature LH surge rate was significantly lower with PPOS (3.1%) compared to GnRH-ant (20.1%) (odds ratio, 0.21; 95% confidence interval, 0.11–0.36). No significant differences were found in total gonadotropin dose (2400IU for PPOS vs 2400IU for GnRH-ant, p = 0.136), the number of oocyte retrieval (n = 15 vs n = 15, p = 0.484), oocyte maturation rate (78.8% vs 77.8%, p = 0.275), fertilization rate (73.0% vs 72.0%, p = 0.412), viable embryo rate per oocyte retrieval (40% vs 40%, p = 0.890), and good quality blastocyst rate (72.0% vs 69.6%, p = 0.092). However, the good quality day-3 embryo rate was significantly lower with PPOS (37.2% vs 49.1%, p < 0.05). There were no differences in the incidence of moderate-to-severe OHSS (0.3% vs 0.7%, p = 0.481). In FET cycles, the pregnancy outcomes, such as implantation rate (43.1 % vs 51.9 %, p = 0.013) and clinical pregnancy rate (46.5% vs 54.7%, p = 0.027) were significantly lower with PPOS, however, no significant differences were found in ongoing pregnancy rate (75.6% vs 80.5%, p = 0.325), and live birth rate (72.4% vs 79.5 %, p = 0.142).
Limitations, reasons for caution
This was a retrospective cohort study conducted in a single center. The participants in this study were limited to Japanese ethnicity. The results need to be validated across different centers and other ethnicities.
Wider implications of the findings
This is the first report assessing the reproductive outcomes on PPOS using CMA, widely used in Japan. The PPOS with CMA significantly suppressed the premature LH surge rate compared to GnRH-ant protocol, without decrease in oocyte maturation rate.

Abstract
BACKGROUND Low skeletal muscle area or density, such as myosteatosis, identified on computed tomography (CT) is associated with poor prognosis in patients with cardiovascular diseases. However, there is a lack of evidence regarding the clinical process of skeletal muscle decline as a short-term change during acute care settings. This study focused on the use of routine CT imaging for aortic disease management and investigated the changes in skeletal muscle before and after acute care. METHODS This prospective study included 123 patients who underwent abdominal CT before and after acute care. The all-abdominal and each abdominal muscle areas were divided into eight parts (e.g. rectus abdominis, psoas, and erector spine), and their areas and densities were measured at the third lumbar vertebra level after the patients were discharged and de-identified with blinding to avoid measurement bias. Short physical performance battery (SPPB) was measured at the start and end of in-hospital cardiac rehabilitation. A generalized linear model with patients as random effects was made to investigate skeletal muscle loss during acute care. Multivariate linear regression analysis was also used to assess the relationship between the change in skeletal muscle during acute care and SPPB during in-hospital cardiac rehabilitation. RESULTS The median age of the patients was 70 (interquartile: 58-77) years, and 69.9% (86/123) were men. The median day between acute care from the day of surgery or hospital admission and follow-up CT was 7 (interquartile: 3-8) days. Overall muscle density declined after acute care (estimate value: -3.640, 95% confidence interval [CI]: -4.538 to -2.741), and each abdominal muscle density consistently declined (interaction: F value = 0.099, P = 0.998). In contrast, there was no significant change in the overall muscle area (estimate value: -0.863, 95% CI: -2.925 to 1.200). Changes in the muscle area were different for each skeletal muscle (interaction: F value = 2.142, P = 0.037), and only the erector spine muscle significantly declined (estimate value: -1.836, 95% CI: -2.507 to -1.165). After adjusting for confounding factors, a greater decline in muscle density was associated with lower recovery score on SPPB (β = 0.296, 95% CI: 0.066 to 0.400). CONCLUSIONS Muscle density consistently declined after acute care, especially the erector spine muscles, which also significantly decreased in size. A higher decline in muscle density was associated with a slower recovery of physical function during in-hospital cardiac rehabilitation in patients with aortic diseases.

Low skeletal muscle density combined with muscle dysfunction predicts adverse events after adult cardiovascular surgery. Nutr Metab Cardiovasc Dis 2021; 31:1782-1790.

Abstract
BACKGROUND AND AIMS Although muscle dysfunctions are widely known as a poor prognostic factor in patients with cardiovascular disease, no study has examined whether the addition of low skeletal muscle density (SMD) assessed by computed tomography (CT) to muscle dysfunctions is useful. This study examined whether SMDs can strengthen the predictive ability of muscle dysfunctions for adverse events in patients who underwent cardiovascular surgery. METHODS AND RESULTS We retrospectively reviewed 853 patients aged ≥40 years who had preoperative CT for risk management purposes and who measured muscle dysfunctions (weakness: low grip strength and slowness: slow gait speed). Low SMD based on transverse abdominal CT images was defined as a mean Hounsfield unit of the psoas muscle <45. All definitions of muscle dysfunction (weakness only, slowness only, weakness or slowness, weakness and slowness), the addition of SMDs was shown to significantly improve the continuous net reclassification improvement and integrated discrimination improvement for adverse events in all analyses (p < 0.05). Low SMDs combined with each definition of muscle dysfunction had the highest risk of all-cause death (hazard ratio: lowest 3.666 to highest 6.002), and patients with neither low SMDs nor muscle dysfunction had the lowest risk of all-cause and cardiovascular-related events. CONCLUSION The addition of SMDs consistently increased the predictive ability of muscle dysfunctions for adverse events. Our results suggest that when CT is performed for any clinical investigation, the addition of the organic assessment of skeletal muscle can strengthen the diagnostic accuracy of muscle wasting.

Abstract
OBJECTIVE Currently, several near-infrared spectroscopy oximetry devices are used for detecting cerebral ischemia during cardiopulmonary bypass (CPB) surgery. We investigated whether two different models of near-infrared spectroscopy oximetry devices affect the assessment of cerebral ischemia and its management during CPB. METHODS From January 2017 to August 2017, 70 adult cardiovascular surgery cases were randomly assigned to 1 of 2 different near-infrared spectroscopy oximetry devices. The devices were INVOS 5100C (Medtronic, Minneapolis, MN, USA) (group I; n = 35) and FORE-SIGHT ELITE (CAS Medical Systems, Branford, CT, USA) (group F; n = 35). RESULTS There were no significant differences in patient characteristics. The rSO2 values were significantly higher for patients in group F than for patients in group I. Scalp-Cortex distance showed negative correlations with the mean rSO2 values in group I (P = 0.01). Interventions for low rSO2 during CPB for groups I and F were increase perfusion flow (13:5; P = 0.03), blood transfusion (7:1; P = 0.02), and both (6:1; P = 0.04), respectively. The Scalp-Cortex distance in group I was significantly longer in patients who required intervention than in patients who did not (17.1 ± 2.5 vs 15.1 ± 1.6 mm; P = 0.007). CONCLUSIONS It is inappropriate to use the same intervention criteria for different near-infrared spectroscopy oximetry devices. Moreover, brain atrophy influence rSO2 values depending on device selection. It is important to note that inappropriate device selection may misguide perfusionists into performing unnecessary or excessive intervention during CPB.

Background
Atrial tachycardias (ATs) are often seen in the context of AF ablation.
Objectives
We evaluated the role of the Marshall bundle (MB) network in left atrial (LA) ATs using high-density high-spatial resolution 3D mapping.
Methods
199 post-AF ablation LA tachycardias were mapped in 140 consecutive patients (112 (80%) males, mean age: 61.8 years); 133 (66.8%) were macro-reentrant and 66 (33.2%) were scar-related re-entry. MB-dependent perimitral AT (PMAT) was diagnosed where the difference between the post pacing interval and the tachycardia cycle length (PPI-TCL) was <20ms in parts of the expected MB-dependent perimitral circuit (within the VOM, the ridge between the left pulmonary veins and LA appendage (LAA), the anterior LA and between 6- and 11-o’clock of the mitral annulus) and the PPI-TCL was >20ms in areas bypassed by the VOM (the distal coronary sinus (CS), the posterior LA and the mitral isthmus). MB-related re-entry was diagnosed by PPI-TCL <20ms at the left lateral ridge, posterior base of LAA, inferolateral LA or VOM ostium; and PPI-TCL >20ms in the septal annulus. Typically, in MB-dependent localized re-entry, the earliest activation was found along the MB-LA endocardial connection or MB-CS epicardial connection.
Results
The MB network was found to participate in 60 (30.2%) re-entrant ATs, 31 PMATs and 29 localized re-entries. High-frequency multiphasic fragmented electrograms with long duration were often recorded endocardially or epicardially at the MB-LA or MB-CS connections. The amplitude and duration of these signals were 0.5 ± 0.79 mV and 65 ± 40 ms for MB-PMATs and 0.26 ± 0.28mV and 122 ± 67 ms for MB-localized re-entries. Unipolar EGMs at the site of endocardial-epicardial breakthrough had a rS pattern in all MB-related ATs. Of 60 MB-related ATs, 49 (81.6%) terminated with RF ablation, 44 (73.3%) at the MB-LA junction and 5 (8.3%) at the MB-CS junction, while 9 (15%) terminated after 2.5-5 cc of alcohol infusion inside the vein of Marshall (VOM). Of the 31 MB-related macroreentrant ATs, 17 (54.8%) terminated at the MB-LA junction, 5 (16.1%) at the MB-CS junction and 7 (22.6%) with alcohol infusion inside the VOM. Two macroreentries (6.5%) using the MB did not terminate with RF energy either endocardially at the MB-LA junction or epicardially at the MB-CS junction, and we were unable to identify or cannulate the VOM for ethanol infusion. Of the 29 localized re-entrant ATs using the MB, 27 (93.1%) terminated at the MB-LA junction, none terminated at the MB-CS junction and 2 (6.9%) terminated after alcohol infusion. After a mean follow up of 12 months, only 4 patients (6.7%) had AT recurrence.
Conclusions
MB re-entrant ATs accounted for up to 29% of the left ATs after AF ablation. Ablation of the MB-LA or CS-MB connections or alcohol infusion inside the VOM is required to treat these arrhythmias. Abstract Figure.

Introduction
Although muscle dysfunction is widely known as a poor prognostic factor in patients with cardiovascular disease, no study has examined whether the addition of low skeletal muscle density (SMD) assessed by computed tomography (CT) to muscle dysfunction is useful.
Purpose
The present study aimed to examine whether SMDs can strengthen the predictive ability of muscle dysfunction for adverse events in patients who underwent cardiovascular surgery.
Methods
We retrospectively reviewed 853 patients (median age: 69 years, 65.1% male) aged ≥40 years who had preoperative CT for risk management purposes and muscle dysfunctions measured during postoperative cardiac rehabilitation. Muscle dysfunctions were determined from weakness (low grip strength) and slowness (slow gait speed) based on the Asia Working Group for Sarcopenia. Low SMD based on transverse abdominal CT images was defined as a mean Hounsfield unit of the psoas muscle <45. To examine the complementary prognostic value for all-cause deaths, all-cause events, and cardiovascular-related events when low SMDs were added to four patterns of muscle dysfunction (weakness only, slowness only, weakness or slowness, and weakness and slowness), the continuous net reclassification improvement (cNRI) and integrated discrimination improvement (IDI) index were calculated.
Results
For all definitions of muscle dysfunction, the addition of SMDs was shown to significantly improve the cNRI (estimates: 0.377 to 0.468 for all-cause death, 0.220 to 0.248 for all-cause events, 0.308 to 0.322 for cardiovascular-related events) and IDI (estimates: 0.005 to 0.011 for all-cause death, 0.005 to 0.010 for all-cause events, 0.009 to 0.012 for cardiovascular-related events) in all analyses. Low SMDs combined with muscle dysfunctions were associated with the highest risk of all-cause death (Figure 1: A-D). Patients with neither low SMDs nor muscle dysfunction had the lowest risk of all-cause events and cardiovascular-related events (Figure1: E-L).
Conclusion
The predictive ability of muscle dysfunction for adverse events was consistently increased by addition of SMDs in patients who underwent cardiovascular surgery. Our results suggest that when CT is performed for any clinical investigation, the addition of the organic assessment of skeletal muscle can strengthen the diagnostic accuracy of muscle wasting.

Abstract
Objectives Postoperative pleural effusion (PE) is common after pediatric cardiac
surgery, and if prolonged can lead to the deterioration of the general
condition due to malnutrition and result in death. This study aims at
identifying the prognostic factors of prolonged PE after pediatric cardiac
surgery. Design and settings: Patients were divided into the effective
(with chest tube removal within 10 days after medical therapy) and
ineffective (with chest tube in place for more than 10 days) groups. The
factors were compared between the two groups retrospectively. Participants Participants included patients who had prolonged PE after cardiac surgery in
national center for child and health development between October 2014 and
October 2017. Main outcome measures Baseline characteristics and procedure details were compared between the two
groups to determine the predictor of prolonged PE. White blood cell count,
platelet count, neutrophil-to-lymphocyte ratio, hemoglobin level, serum
total protein level, serum albumin level, blood fibrinogen level, serum
creatinine level, etc. were examined. Results Twenty patients were included. Between the two groups, no significant
differences in baseline characteristics, such as age, weight, and sex were
found, and significant differences were observed only in the NLR change
ratio (effective group, 5.1 [4.1–8.0] versus ineffective group, 11.9
[9.9–14.1]; P = 0.01). Conclusions NLR change ratio is a potential prognostic factor of prolonged PE, including
chylothorax, after pediatric cardiac surgery.

Abstract
BACKGROUND The details and consequences of a small aortic annulus among transcatheter aortic valve replacement (TAVR) patients remain uncertain. This study investigated the short-term outcomes in patients with small annular size and compared the 30-day outcome between intra- and supra-annular devices, with similar outer casing diameter in this subgroup.Methods and Results:Cases registered in the Japanese national TAVR registry between August 2013 and December 2017 were analyzed. Among a total of 5,870 registered patients, 647 (11.0%) had small annulus (area ≤314 mm2) measured by multi-detector computed tomography. Patients with a small annulus had a significantly smaller indexed effective orifice area (iEOA, 1.10 cm2/m2[0.92-1.35] vs. 1.16 cm2/m2[0.96-1.39], P<0.001) and higher mean pressure gradient (mPG, 10.0 mmHg [6.9-14.2] vs. 8.5 mmHg [6.0-11.5], P<0.001) compared with a normal-sized annulus. Among patients with a small annulus, those receiving a 20 mm intra-annular device had a smaller iEOA (0.94 cm2/m2[0.78-1.06] vs. 1.07 cm2/m2[0.8-1.24], P=0.001) and higher mPG (14.0 mmHg [10.0-18.5] vs. 11.0 [7.0-14.0], P<0.001) compared with those receiving a 23-mm supra-annular device, although the incidence of paravalvular leakage (≥moderate) was similar (14.4% vs. 16.5%, P=0.69). CONCLUSIONS Patients with a small annulus were associated with less hemodynamic improvement. A supra-annular device is associated with better echocardiographic improvement in patients with a small annulus, without increasing paravalvular leakage.

Abstract
From April 2011 to March 2020, 87 patients with type A intramural haematoma and acute aortic dissection with thrombosed false lumen of the ascending aorta were treated at Kitasato University Hospital. The initial watch-and-wait strategy without emergency aortic repair was taken in 52 cases in which the maximum aortic diameter was ≤50 mm, pain score on arrival at our hospital was ≤3/10 on the numerical rating scale and there was no ulcer-like projection (ULP) in the ascending aorta. Eleven patients who fulfilled the criteria but developed cardiac tamponade underwent emergency pericardial drainage without aortic repair. Among these 11 patients, 3 patients developed an aortic event during the hospitalization; 1 patient developed enlargement of the ULP 18 days later but refused surgery, another patient developed rupture of the dissected brachiocephalic artery 4 days later and underwent emergency repair of the ascending aorta and the brachiocephalic artery and the other patient developed a new ULP in the ascending aorta 14 days later and underwent aortic repair. All 11 patients were discharged home. During follow-up (3.0 ± 2.4 years), 1 patient developed a recurrent type A acute aortic dissection and underwent emergency aortic repair 29 months later. There was no aorta-related death.

Abstract
BACKGROUND When an internal iliac artery (IIA) has to be embolized during endovascular aneurysm repair (EVAR), buttock claudication sometimes poses problems. However, there is no established method to evaluate intraoperative blood flow to the gluteal muscles.Methods and Results:Gluteal regional oxygen saturation (rSO2) was monitored using near-infrared spectroscopy (NIRS) during surgery, and changes in rSO2were compared with treatment results. Twenty-seven patients who underwent EVAR and IIA embolization at our institution between April 2019 and May 2020 were included in this study. The association between intraoperative changes in rSO2and postoperative incidence of buttock claudication was analyzed. Furthermore, the presence or absence of communication between the superior and inferior gluteal arteries and the intraoperative changes in rSO2were compared to ascertain whether rSO2reflects blood flow change. Postoperative buttock claudication occurred in 4 of 19 patients (21%) with unilateral occlusion of IIA and in 4 of 8 patients (50%) with bilateral occlusion of IIAs. rSO2was found to decrease significantly further in patients with buttock claudication than in patients without buttock claudication (-15±12% vs. -4±16%, P<0.05). In addition, rSO2was predominantly lower in patients without the communication between the superior and inferior gluteal arteries than in those with the communication. CONCLUSIONS Gluteal rSO2is useful as an indicator of intraoperative gluteal blood flow.

Abstract
Abstract
Background
Although patients with acute myocardial infarction (AMI) complicated by cardiogenic shock, morbidity and mortality remain high even with early revascularization and modern intensive care.
Culprit artery and prognosis were associated in patients with acute myocardial infarction.
Purpose
Evaluation of short- and long-term prognosis of AMI with cardiogenic shock by right coronary artery (RCA) and left coronary artery (LCR)
Method
We investigated 3400 AMI patients (age 68.8±12.7 y.o.) were enrolled from Mie ACS registry. They were divided into 4 groups according to the culprit artery and presence or absence of cardiogenic shock: RCA without shock n=1114, RCA with shock n=74, LCA without shock n=2028, LCA with shock n=184. Primary endpoint was defined as all-cause mortality.
Results
During the median follow-up periods with 743 days, 12.6% of the patients experienced all-cause death. RCA and LAC with shock groups demonstrated significantly higher in-hospital mortality compared to groups without shock (p<0.001, Figure 1A). Interestingly, after discharge, LCA with shock group showed significant higher all-cause mortality compared with other 3 groups. Surprisingly, RCA with shock group showed similar favorable prognosis to that of without shock groups (Figure 1B). Multivariate analyses for after discharge mortality showed that LCA with shock group was strongest independent poor prognostic factor with hazard ratio of 2.3 (95% CI 1.4–3.7), but RCA with shock group was not.
Conclusion
Association of cardiogenic shock is the hazardous risk factor for cases with AMI, especially LCA infarction. Surprisingly, RCA AMI cases with shock showed favorable prognosis as well as AMI without shock.

Of the 756 patients who registered prospective, multicenter, observational study of patients with HFpEF (PURSUIT-HFpEF) registry, 481 cases with clinical frailty score (CFS) and prognosis after discharge were examined. Frailty was defined as CFS ≥5. Outcomes were composite endpoint of all-cause death and heart failure readmission, and all-cause mortality. We compared outcomes between patients without and with frailty, and sought to identify factors which were associated with increase in clinical frailty score by the correlation analysis and linear regression analysis.
Results
Of 481 patients, 131 patients (27.2%) were frail. Male gender was less in patients with frailty than those without frailty (26.7% vs 73.3%, P<0.001). Frail patients had higher age (85.2±7.3 vs 78.7±9.4 years, P<0.001). During follow-up period of 396 [343, 697] days, composite endpoint (Kaplan-Meier event rate estimates, 77% vs. 60%; log-rank P<0.001), and all-cause mortality (Kaplan-Meier event rate estimates, 57% vs. 28%; log-rank P<0.001) was higher in patients with frailty than those without frailty. Multivariate Cox regression analysis revealed frailty was significantly and independently associated with mortality (HR=1.40, 95% CI=1.17–1.68, P<0.001). CFS was significantly correlated with age (r=0.401, P<0.001), sex (r=0.223, P<0.001), body mass index (r=−0.146, P=0.001), hemoglobin (r=−0.148, P=0.001), albumin (r=−0.222, P<0.001), left ventricular diastolic diameter (r=−0.184, P<0.001), interventricular septum thickness (r=−0.124, P=0.008), left ventricular mass (r=−0.217, P<0.001), tricuspid annular plane systolic excursion (r=−0.165, P=0.001), and tricuspid regurgitation pressure gradient (TRPG) (r=0.189, P<0.001). Multivariate linear regression analysis using these factors as covariates revealed age (standardized β: 0.337, P<0.001), sex (standardized β: 0.120, P=0.014), albumin (standardized β: −0.151, P=0.003) and TRPG (standardized β: 0.129, P=0.005) were significantly and independently associated with increase in clinical frailty score.
Conclusion
Our results suggest that not only nutritional factors but also a cardiac factor were associated with frailty, and frailty was associated with mortality in patients with HFpEF. Improvement of hemodynamics in HFpEF patients as well as improvement of nutrition might contribute to alleviation of frail in HFpEF patients.

Abstract
Sickle cell trait (SCT), a benign hematological condition affecting approximately 300 million individuals globally, is associated with an increased risk of vaso-occlusive disease. However, the risks related to surgery employing cardiopulmonary bypass in patients with SCT are not well established. Herein, we report the case of a 27-year-old African American man with SCT who underwent an emergency aortic repair for acute Stanford type A aortic dissection using hypothermic circulatory arrest. The patient developed a sickle cell crisis, which was followed by spontaneous splenic infarction and rupture, nonocclusive mesenteric ischemia, and spinal infarction.

Abstract
How do people hear sounds? As a counterpart of Prof. G. V. Békésy's traveling wave theory, we have proposed resonance theory of outer hair cells and cochlear standing wave theory, respectively. Based on these proposals, this paper develops a transmission-line-based cochlear standing wave model. Since the macroscopic cochlear model is designed as it looks like, various auditory physiology can be explained. Transient analyses with pure-tone excitation and Gaussian pulse excitation are carried out, and Prof. D. Kemp's otoacoustic emission (OAE) is demonstrated successfully.Clinical relevance-Our new model has a great potential to explain auditory physiology including structural inner disorders, hearing loss, and even tinnitus.

Abstract
Right minithoracotomy has become the standard approach along with sternotomy in mitral and tricuspid valve surgery. Transareolar incision, compared with submammary incision, is advantageous in that it often allows better angle for antegrade cardioplegia cannulation through the main wound. It also provides a better cosmesis. In this retrospective study, we reviewed the 11 patients who underwent mini-mally invasive tricuspid valve repair through transareolar approach from 2016 to 2019. Mean age was 58 years, 8 ware female, mean body weight was 53 kg, and mean body surface area was 1.47 m2. Causative pathology was atrial septal defect in 8, trauma in 1, tumor in 1 and pacemaker lead infection in 1. Homologous blood transfusion was performed in 1. Hospital mortality occurred in 1;a patient on dialysis who underwent tricuspid valve repair with removal of vegetation for pacemaker lead infection died of uncontrollable acidosis. There was no late death. Transareolar approach was considered a feasible option for tricuspid valve surgery.

Watch-and-wait strategy for type A intramural haematoma and acute aortic dissection with thrombosed false lumen of the ascending aorta: a Japanese single-centre experience. Eur J Cardiothorac Surg 2020; 58:590-597. [DOI: 10.1093/ejcts/ezaa080] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Revised: 02/08/2020] [Accepted: 02/12/2020] [Indexed: 01/16/2023] Open
Abstract
Abstract
OBJECTIVES
In this study, we investigated the early and midterm outcomes of initial watch-and-wait strategy for Stanford type A intramural haematoma and acute aortic dissection with thrombosed false lumen of the ascending aorta in patients with a maximum aortic diameter of ≤50 mm, pain score of ≤3/10 and no ulcer-like projection in the ascending aorta.
METHODS
Inpatient and outpatient records were retrospectively reviewed.
RESULTS
Of the 81 patients with type A intramural haematoma and acute aortic dissection with the thrombosed false lumen of the ascending aorta between April 2011 and April 2019, a watch-and-wait strategy was selected in 46 patients. The mean age of the patients was 68 years, and 22 (48%) patients were female. Ten patients underwent emergency pericardial drainage for cardiac tamponade at the time of presentation and 8 patients underwent aortic repair during hospitalization for new ulcer-like projection, re-dissection or rupture. In-hospital mortality occurred in 2 (4%) patients. During follow-up, survival at 1 and 2 years was 95% and 92%, respectively. There was no significant difference in survival or aortic events between patients in whom the watch-and-wait strategy and emergency surgical treatment were indicated.
CONCLUSIONS
The early and midterm outcomes of the initial watch-and-wait strategy were favourable for type A intramural haematoma and acute aortic dissection with the thrombosed false lumen of the ascending aorta in Japanese patients with a maximum aortic diameter of ≤50 mm, pain score of ≤3/10 and no ulcer-like projection. Further study is required to show the safety of this strategy.

Abstract
The Ross Reversal operation is a breakthrough strategy first reported by Flynn et al. in 2007. In a reoperation for pulmonary autograft dysfunction after the Ross operation, an excised autograft can be preserved by reusing it in a native pulmonary position. We report a case wherein we used a new approach to excise the autograft valve with less invasion. The patient underwent a modified Ross Reversal operation concomitant with aortic root replacement and recovered without any complications. Our new approach enables a safer operation with improved valve function.

Abstract
OBJECTIVES A novel surgical strategy using haemodynamic analyses based on virtual operations with computational simulations has been introduced for complicated pulmonary stenosis. We evaluated the efficacy of this strategy. METHODS Six patients were enrolled. Before surgery, the optimal pulmonary arteries were constructed based on computational fluid dynamics using 3-dimensional computed tomography. Energy loss (EL, mW) and wall shear stress (WSS, Pa) were calculated. We compared the shapes of preoperative and optimal pulmonary arteries to determine the surgical strategy, including the incision line and the shape of the patch (virtual surgery). EL and WSS were compared between virtual and actual surgeries using flow analysis. RESULTS In both the virtual and actual surgeries, postoperative EL tended to be lower than the preoperative EL, although there were no significant differences (P = 0.12 and P = 0.17, respectively). The mean WSS in the virtual surgery was significantly reduced from 112 ± 130 Pa to 25 ± 24 Pa (P = 0.028). After the actual surgery, the mean WSS was also significantly reduced to 30 ± 23 Pa (P = 0.047). There were no significant differences in the values for EL and WSS before and after surgery or between virtual and actual surgery (P = 0.94 and P = 0.85, respectively). CONCLUSIONS Pulmonary artery plasty, using computational fluid dynamics based on virtual surgery, is an efficient surgical strategy. This novel strategy can easily and successfully provide an optimal pulmonary artery plasty equivalent to that using the conventional approach, which is based on the surgeon's personal experience and judgement.

Abstract
Abstract
OBJECTIVES
Although skeletal muscle density (SMD) is useful for predicting mortality, the cut-off in an acute clinical setting is unclear, especially in patients with cardiovascular disease (CVD). This study was performed to determine the preoperative SMD cut-off using the psoas muscle and to investigate the effect on postoperative outcomes, including sarcopaenia, in CVD patients.
METHODS
Preoperative psoas SMD was measured by abdominal computed tomography in CVD patients. Postoperative sarcopaenia was defined according to the criteria of the Asia Working Group for Sarcopaenia. The Youden index was used to test the predictive accuracy of survival models. The prognostic capability was evaluated using multivariable survival and receiver operating characteristic curve analyses.
RESULTS
Continuous data were available for 1068 patients (mean age 65.5 years; 63.6% male). A total of 105 (9.8%) deaths occurred during the 1.99-year median follow-up period (interquartile range 0.71–4.15). The psoas SMD cut-off estimated by the Youden index was 45 Hounsfield units with high sensitivity and moderate specificity for all-cause mortality and was consistent in various stratified analyses. After adjusting for the existing prognostic model, EuroSCORE II, preoperative and postoperative physical status, psoas SMD cut-off was predicted for mortality (hazard ratio 2.42, 95% confidence interval 1.32–4.45). The psoas SMD cut-off was also significantly associated with postoperative sarcopaenia and provided additional prognostic information to EuroSCORE II on receiver operating characteristic curve analysis (area under the curve 0.627 vs 0.678, P = 0.011).
CONCLUSIONS
Reduced psoas SMD was associated with postoperative mortality and added information prognostic for mortality to the existing prognostic model in CVD patients.

Abstract
Abstract
Background
Transcatheter aortic valve implantation (TAVI) has been widely accepted strategy of the treatment for aortic stenosis in patients at intermediate to high or prohibitive surgical risk. The Asian people are of smaller body size compared to Western people. As the result, Asian people have smaller aortic annulus size, which accommodate only smaller transcatheter heart valves (THVs), however, the details and consequences of small aortic annulus size in TAVI is uncertain.
Purpose
The purposes of this study were to clarify the short-term outcomes of TAVI in patients with small annulus and the differences of intra-annular and supra-annular THVs in small annulus using Japanese national TAVI registry.
Methods
Multi-detector computed tomography (MDCT) was performed before TAVI and the annulus area was registered. We compared the 30-day clinical outcomes between patients with and without small annulus (annulus area 3.14cm2). Further investigation to compare intra-annular and supra-annular THVs in patients with small annulus was conducted.
Results
The total of 5,870 patients (103 sites in Japan) who underwent TAVI between August 2013 to December 2017 were enrolled in this study. Out of 5,870 patients, 647 had small annulus.
Thirty-day mortality, new pacemaker implantation and stroke rate were comparable between patients with and without small annulus. Echocardiography within 30 days after TAVI revealed that patients with small annulus had significantly smaller indexed effective orifice area (iEOA, 1.10.cm2/m2 [0.92–1.35] vs. 1.16 cm2/m2 [0.96–1.39], p<0.001), higher mean pressure gradient (10.0 mmHg [6.9–14.2] vs. 8.5 mmHg [6.0–11.5], p<0.001) and lower frequency of paravalvular leakage moderate (17.3% vs. 24.4%, p<0.001). Patient-prosthesis mismatch (PPM) were more frequent in patients with small annulus (p=0.002). Logistic regression analysis revealed that small annulus (OR: 1.82; 95% CI: 1.45–2.30, p<0.001), female gender (OR: 0.54; 95% CI: 0.42–0.70, p<0.001), weight (OR: 1.03; 95% CI: 1.02–1.04, p<0.001), height (OR: 1.04; 95% CI: 1.02–1.05, p<0.001), hyperlipidemia (OR: 1.25; 95% CI: 1.07–1.47, p=0.006), femoral access (OR: 0.80; 95% CI: 0.66–0.97, p=0.026) were significantly associated with the PPM after TAVI.
The use of SAPIEN 3 20mm THV in patients with small annulus was associated with the smaller iEOA (0.94 cm2/m2 [0.78–1.06] vs. 1.07 cm2/m2 [0.84–1.24], p=0.001) and higher mean pressure gradient (14.0 mmHg [10.0–18.5] vs. 11.0 [7.0–14.0], p<0.001) compared to the usage of Evolut R 23 mm THV. The rate of paravalvular leakage more than moderate was similar in both THVs (14.4% vs. 16.5%, p=0.69).
Conclusions
Small annulus did not affect clinical 30-day outcomes, however, small annulus was associated with smaller iEOA and higher mean pressure gradient. Supra-annular device might contribute the better hemodynamical improvement in patients with small annulus without increase of paravalvular leakage.

Abstract
Abstract
Background
It has been reported that intra-aortic balloon pumping (IABP) support for acute myocardial infarction (AMI) with cardiogenic shock did not reduce short and long-term mortality. However, the significance of IABP support for AMI patients with extracorporeal membrane oxygenation (ECMO) therapy remains unclear. The aim of this study was to investigate the effect of IABP support for the short and long-term outcome in AMI patients who received ECMO.
Methods
Using the database of the Osaka Acute Coronary Insufficiency Study (OACIS), 12,093 consecutive AMI patients were enrolled in this analysis. Among these, we analyzed 520 patients with ECMO. We classified the patients into two groups, patients who received IABP support [IABP group (n=460)] and patients who did not [no IABP group (n=60)]. Primary outcome was all-cause death.
Results
Study patients had following baseline clinical characteristics, age: 66.8±12.0 year old, male: 78.3%, diabetes mellitus: 41.0%, Killip class≥II: 66.2%, multi-vessel disease: 72.3%, peak creatine phosphokinase >3000IU/L: 68.1%. During a mean follow-up period of 349±625 days, Kaplan-Meier analysis revealed that the all-cause death was significantly lower in IABP group than no IABP group for 30-day (45.5% vs 72.7%, log-rank p<0.001) and long-term (66.2% vs 78.4%, Log rank p=0.005) follow-up period. Cox multivariate analysis revealed that IABP support was significantly associated with a reduced risk of mortality (Hazard ratio 0.445, 95% confidence interval 0.289 to 0.687, p<0.001).
Conclusions
IABP support for AMI patients with ECMO was significantly associated with reduced risks of the short and long-term mortality, suggesting that IABP support might contribute to improvement of the survival in AMI patients with ECMO.

Abstract
Abstract
Background
Intra-Aortic Balloon Pumping (IABP) was widespread used in cases of Acute Coronary Syndrome (ACS) at daily clinical situation in Japan, even though the efficacy of IABP in AMI patients with cardiogenic shock was not proved. The aim of this study was to investigate the efficacy of IABP use in ACS patients in Japan.
Methods
We investigated 2-year all-cause-mortality of 2,660 enrolled ACS patients including 358 patients with IABP and 2,302 patients without IABP from Mie ACS registry.
Results
We compared a 1:1 propensity score-matched cohort of 426 ACS patients with or without IABP (n=213, respectively). 2-year mortality was significantly higher in patients with IABP than without IABP (p=0.02, Figure A). In addition, IABP usage was independent predictor of mortality with hazard ratio of 1.6 by multivariate analysis. However, 2-year mortality was not statistically different between 2 groups only when analyzed patients with shock (p=0.60, Figure B).
Figure 1
Conclusion
IABP was not commonly recommended in ACS patients. However, IABP was might as well used in some situation especially in shock.

Abstract
Abstract
Background
Malnutrition is associated with adverse prognosis in heart failure patients. However, in patients with heart failure with preserved ejection fraction (HFpEF), the effects of change in nutritional status during hospitalization on prognosis is unknown. Geriatric nutritional risk index (GNRI) is a widely used objective index for evaluating nutritional status. Low GNRI (<92) has moderate or severe nutritional risk and high GNRI (≥92) has no or low nutritional risk.
Purpose
The purpose of this study was to clarify the effect of change in GNRI during hospitalization on one-year mortality and the association between the value of GNRI and one-year mortality in patients with HFpEF.
Methods
We prospectively registered patients with HFpEF in PURSUIT-HFpEF registry when they were hospitalized for heart failure in 29 hospitals. Preserved ejection fraction was defined as more than 50% of left ventricular ejection fraction. Of the 486 patients who registered PURSUIT-HFpEF, 228 cases with one-year follow-up data were examined. GNRI was calculated as follows: 14.89 × serum albumin (g/dl) + 41.7 × body mass index/22.
Results
Mean age was 81±10 years and 100 patients (44%) were male. During a median [interquartile range] follow-up period of 374 [342, 400] days, 28 patients (12%) died. Mortality was significantly higher in patients with low GNRI at admission (n=65) than those with high GNRI at admission (n=163) (26% vs. 9%, log-rank P=0.011) and higher in patients with low GNRI at discharge (n=109) than those with high GNRI at discharge (n=119) (22% vs. 6%, log-rank P=0.002). Multivariate analysis with Cox proportional hazard model with patient characteristics at admission revealed that low GNRI at admission was independently associated with mortality (hazard ratio: 0.96, 95% CI: 0.93–0.99, P=0.035) and that with patient characteristics at discharge revealed that low GNRI at discharge was independently associated with mortality (hazard ratio: 0.94, 95% CI: 0.91–0.97, P<0.001). We also compared mortality by dividing patients into 4 group according to whether GNRI was high or low at the time of admission and discharge. Patients with low GNRI at admission and at discharge (n=59) exhibited the highest mortality, on the other hand, patients with high GNRI at admission and low GNRI at discharge (n=50) exhibited higher mortality than those with high GNRI both at admission and at discharge (n=113) (Low and low: 28% vs. High and low: 14% vs. High and high: 6% vs. Low and high: 0%, log-rank P=0.010).
All cause mortality
Conclusion
GNRI at admission or at discharge was independently associated with one-year mortality in patients with HFpEF. Moreover, worsening GNRI during hospitalization is associated with the worse prognosis. It is important to prevent lowering GNRI during treatment of acute decompensated HFpEF.

Abstract
Abstract
Background
Cardiovascular deaths are more frequently in hemodialysis (HD) patients compared to general population. However, difference of prognosis of acute coronary syndrome (ACS) patients with or without HD were not well evaluated.
Purpose
The purpose of this study was to evaluate the clinical and prognostic characteristics of ACS patients with HD compared to that of ACS patients without HD.
Methods
We investigated 3427 ACS patients including 63 HD and 3364 non-HD patients between 2013 and 2017 using date from Mie ACS registry, a retrospective and multicenter registry. The primary outcome was defined as all-cause mortality.
Results
HD patients showed significantly higher prevalence of diabetes mellitus, past treatment of coronary artery disease, history of myocardial infarction and Killip ≥2 compared to non-HD patients (p<0.05, respectively). During the follow-up periods (median 719 days), 425 (12.4%) patients experienced all-cause death. HD patients demonstrated the higher all-cause mortality rate compared to that of non-HD patients during the follow-up (11.9% versus 38.1%, p<0.001, chi square). Kaplan Meier survival curves demonstrated that HD and non-HD patients with Killip 1 showed similar 30-day mortality, and Killip ≥2 patients also showed similar prognosis (Left side of figure). On the other hand, all cause mortality at 2 years were higher in Killip 1 HD patients compared to Killip 1 non-HD patients and similar between Killip 1 HD patients and Killip ≥2 non-HD patients in the 30 days landmark analysis (Right side of figure). In addition, cox regression analyses for all cause mortality demonstrated that HD was a strongest independent prognostic factor not of 30-day mortality but of after 30-day mortality with hazard ratio of 4.09 (95% confidential interval: 2.32–7.21, p<0.001).

Conclusion
Careful management are required in chronic phase for ACS patients with HD even in Killip 1 classification.

Abstract
Cannulation for cardiopulmonary bypass is a fundamental procedure in cardiac surgery. Different surgeons perform it in a different routine way without any particular reason or scientific evidence, and therefore, trainees should remember and follow the routine of each attending surgeon to avoid confusion or needlestick accidents. In this section, the author's routine cannulation technique is described.

Ketoacidosis related to sodium glucose cotransporter 2 inhibitors after emergency coronary surgery. Interact Cardiovasc Thorac Surg 2019; 29:323–324. [PMID: 30968118 DOI: 10.1093/icvts/ivz091] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2018] [Revised: 02/23/2019] [Accepted: 03/11/2019] [Indexed: 11/13/2022] Open
Abstract
Sodium glucose cotransporter 2 inhibitors are currently widely used antihyperglycaemic medications that are considered to be associated with euglycaemic diabetic ketoacidosis. We report 2 cases of patients who received sodium glucose cotransporter 2 inhibitors until emergency coronary artery bypass grafting (CABG) and developed euglycaemic ketoacidosis after surgery; they were treated with sugar replenishment and insulin infusion. In one case, coronary angiography revealed a spastic change of the bypass graft possibly due to severe acidosis. A rapid diagnosis and proper intervention are crucial to achieve better outcomes with CABG.

Abstract
A 92-year-old man with acute heart failure due to severe aortic stenosis underwent transcatheter aortic valve implantation (TAVI). Computed tomography demonstrated severe stenosis of the right common iliac artery, occlusion of the left external iliac artery, and stenosis of the left subclavian artery. Severe calcification was observed in the sinotubular junction, which was considered a risk factor for aortic dissection with transapical TAVI using a balloon-expanding bioprosthetic valve. Therefore, transaortic (TAo) access was the only option for this high-risk surgical patient. As the maximum distance from the aortic valve annulus to the sheath insertion point was less than 60 mm, TAVI was performed transaortically using a vascular graft that extended this distance, in order to avoid sheath dislocation. Our experience demonstrates that vascular graft application is a viable option in patients with an inadequate distance between the aortic valve annulus and the puncture site in TAo-TAVI.

Samurai cannulation (direct true-lumen cannulation) for acute Stanford Type A aortic dissection. Eur J Cardiothorac Surg 2019; 54:498-503. [PMID: 29490035 DOI: 10.1093/ejcts/ezy066] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2017] [Accepted: 01/24/2018] [Indexed: 11/14/2022] Open
Abstract
OBJECTIVES In this study, we investigated early outcomes of patients who underwent surgical aortic repair for acute Stanford Type A aortic dissection at the Kitasato University Hospital and compared the results of Samurai cannulation (direct true-lumen cannulation) with other cannulation options. METHODS Inpatient and outpatient records were retrospectively reviewed. RESULTS Among the 100 patients who were operated on for acute Type A aortic dissection between April 2011 and April 2017, sole Samurai cannulation was used in 61 patients (Group S) and other cannulation options were used in the remaining 39 patients (Group O). No significant difference was observed in preoperative demographics between the groups. True-lumen cannulation was successful in all Group S patients, whereas 3 cannulation-related complications were observed in Group O patients. In Group S, the 30-day and in-hospital mortality occurred in 3 (5%) and 4 (7%) patients, respectively, and in Group O, these occurred in 3 (8%), and 6 (15%) patients, respectively. Four patients in each group (7% and 10%) experienced disabling or fatal strokes. Early mortality or stroke rate between the groups were not significantly different. During follow-up, there was no statistically significant difference between the groups in terms of survival, freedom from aorta-related death or freedom from aortic events. CONCLUSIONS Early outcomes of the initial series of surgery for Stanford Type A aortic dissection with Samurai cannulation was favourable with acceptable mortality and stroke rates without cannulation-related complications. Samurai cannulation represents an easy, safe and reasonable option for cardiopulmonary bypass in surgery for acute Stanford Type A aortic dissection.

Usefulness of Silent MR Angiography for Intracranial Aneurysms Treated with a Flow-Diverter Device. AJNR Am J Neuroradiol 2019; 40:808-814. [PMID: 31048297 DOI: 10.3174/ajnr.a6047] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2019] [Accepted: 03/25/2019] [Indexed: 11/07/2022]
Abstract
BACKGROUND AND PURPOSE The flow-diverter device has been established as a treatment procedure for large unruptured intracranial aneurysms. The purpose of this study was to compare the usefulness of Silent MR angiography and time-of-flight MRA to assess the parent artery and the embolization state of the aneurysm after a flow-diverter placement. MATERIALS AND METHODS Seventy-eight large, unruptured internal carotid aneurysms in 78 patients were the subjects of this study. After 6 months of treatment, they underwent follow-up digital subtraction angiography, Silent MRA, and TOF-MRA, performed simultaneously. All images were independently reviewed by 2 neurosurgeons and 1 radiologist and rated on a 4-point scale from 1 (not visible) to 4 (excellent) to evaluate the parent artery. The aneurysmal embolization status was assessed with 2 ratings: complete or incomplete occlusion. RESULTS The mean scores of Silent MRA and TOF-MRA regarding the parent artery were 3.18 ± 0.72 and 2.31 ± 0.86, respectively, showing a significantly better score with Silent MRA (P < .01). In the assessment of the embolization of aneurysms on Silent MRA and TOF-MRA compared with DSA, the percentages of agreement were 91.0% and 80.8%, respectively. CONCLUSIONS Silent MRA is superior for visualizing blood flow images inside flow-diverter devices compared with TOF-MRA. Furthermore, Silent MRA enables the assessment of aneurysmal embolization status. Silent MRA is useful for assessing the status of large and giant unruptured internal carotid aneurysms after flow-diverter placement.
