Abstract
Cardiovascular disease (CVD) is a common cardiac disorder that leads to heart attacks, strokes, and heart failure. It is primarily characterized by conditions that impact the heart and blood arteries, including peripheral artery disease, arrhythmias, atherosclerosis, myocardial ischemia, congenital heart abnormalities, heart failure, rheumatic heart disease, hypertension, and cardiomyopathies. These conditions are mainly effect the heart and blood vessels, causing blockages or weakened pumping, due to severe hereditary and environmental factors. The frequency of CVD is rising significantly as life expectancy increases. Despite this, no effective treatment or management for its symptoms has been found. One of the most difficult obstacles to overcome, is finding a suitable animal model for drug screening and drug development. Although rodents, mice, swine, and mammals serve as the basis for most animal models of cardiovascular disease, no model accurately captures the epidemiology of the condition. Zebrafish (Danio rerio) have drawn the interest of the international scientific community due to certain shortcomings of the previously discussed animal models because they are smaller, less costly, and have an incredibly high rate of reproduction. This review article emphasizes the significance of using zebrafish as an animal model to investigate the possible facets of cardiovascular disease. Moreover, the ultimate purpose of this review article is to establish the advantages of employing zebrafish over other animal models and to investigate the boundaries of using zebrafish to study human disease. Furthermore, the mechanisms of cardiovascular diseases induction in zebrafish were covered to improve understanding for readers. Finally, the analysis of cardiotoxicity using Zebra fish model, is also explained. In order to stop the health index from deteriorating, the current study also covers some innovative, effective, and relatively safer treatments for treatment and management of cardiotoxicity.

Cerebral Protection With Deep Hypothermic Circulatory Arrest During Total Arch Replacement Using the Arch-First Technique for Acute Aortic Dissection. Cureus 2024; 16:e66640. [PMID: 39132088 PMCID: PMC11317073 DOI: 10.7759/cureus.66640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/10/2024] [Indexed: 08/13/2024] Open
Abstract
OBJECTIVES Stroke remains a serious complication after total arch replacement (TAR). To prevent this, deep hypothermia is commonly employed during TAR. We evaluated the effectiveness of cerebral protection using deep hypothermic circulatory arrest (DHCA) during TAR with the arch-first technique, focusing particularly on patients with acute aortic dissection (AAD). METHODS This retrospective study included 109 consecutive patients with AAD who underwent emergency TAR using the arch-first technique under DHCA, and 147 patients with non-ruptured aneurysm who underwent scheduled TAR using the same technique between October 2009 and July 2022. We reviewed these patients for major adverse events, including stroke and 30-day mortality after surgery. We also analyzed the impact of clinical variables and anatomical features on the occurrence of newly developed stroke after TAR in patients with AAD. RESULTS A newly developed stroke after TAR occurred in 11 (10.1%) patients with AAD. These were attributed to embolism in eight patients, malperfusion in two patients (including one who had been comatose), and low output syndrome in one patient. A stroke occurred in 3 (2.0%) patients with aneurysm, all due to embolism (P = 0.005). The DHCA time was 37 ± 7 minutes for patients with AAD and 36 ± 6 minutes for patients with aneurysm (P = 0.122). The 30-day mortality rate was 10 (9.2%) for patients with AAD and 2 (1.4%) for patients with aneurysm (P = 0.003). In our multivariable analysis, arch vessel dissection with a patent false lumen (double-barreled dissection) was the only significant predictor of newly developed stroke after TAR for AAD (odds ratio, 33.02; P < 0.001). CONCLUSIONS Patients with aneurysm undergoing TAR using the arch-first technique under DHCA experienced significantly better outcomes, in terms of newly developed stroke and 30-day mortality, than those with AAD. Cerebral protection with DHCA during TAR using the arch-first technique continues to be a viable option. Newly developed stroke in patients undergoing TAR for AAD appears to be associated with air emboli deriving from the residual dissection with a patent false lumen in the repaired arch vessels.

Ann Thorac Surg 2024; 117:345-352. [PMID: 36181775 DOI: 10.1016/j.athoracsur.2022.09.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 08/13/2022] [Accepted: 09/19/2022] [Indexed: 11/20/2022]
Abstract
BACKGROUND We developed an adventitial overlay method for reinforcing aortic anastomoses. This study evaluated the midterm morphologic and clinical outcomes of this method. METHODS We harvested and prepared adventitia from a resected aneurysm or dissected aortic wall and performed aortic repair using the adventitial overlay method. At the midterm follow-up, we examined the differences between overlay, inversion, and felt sandwich methods by evaluating the morphologic features of the anastomosis on computed tomography scans. Moreover, we performed macroscopic evaluation of 1 patient who required a second operation. RESULTS Between May 2009 and April 2020, 160 consecutive patients (104 men, 56 women; mean age, 68.6 ± 11 years; range, 39-88 years) underwent thoracic aortic surgery. The overlay technique was successfully performed in 84 cases. The anastomosis sites of the overlay method maintained their morphologic appearance without any clinical complications. The inner diameter ratio of anastomosis/graft was measured by computed tomography, which revealed that the overlay method was not significantly different from inversion and was significantly larger than the felt sandwich method. There was no anastomotic stenosis in the proximal or distal overlay anastomosis. Only 1 patient required a second operation for an enlarged aneurysm of the distal false lumen. We observed that the proximal overlaid adventitia was smoothly attached to the native lumen and was macroscopically indistinguishable from the original intima. CONCLUSIONS This study showed the midterm stability of the overlay technique. The midterm outcome was clinically acceptable. No anastomotic stenosis or pseudoaneurysm formation in either the true aortic aneurysm or dissection cases was observed.

[PMID: 37629368 PMCID: PMC10455504 DOI: 10.3390/jcm12165326] [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: 07/05/2023] [Revised: 08/09/2023] [Accepted: 08/14/2023] [Indexed: 08/27/2023] Open
Abstract
Background: Hybrid thoracic endovascular aortic repair (TEVAR) without median sternotomy is increasingly being performed in high-risk patients with aortic arch disease. The outcomes of hybrid TEVAR were reported to be worse with a more proximal landing zone. This study aims to clarify the effectiveness of zone 1-landing hybrid TEVAR by comparing the outcomes of zone 2-landing hybrid TEVAR. Methods: From April 2008 to October 2020, 213 patients (zone 1: zone 1-landing hybrid TEVAR, n = 82, 38.5%; zone 2: zone 2-landing hybrid TEVAR, n = 131, 61.5%) were enrolled (median age, 72 years; interquartile range [IQR], 65-78 years), with a median follow-up period of 6.0 years (IQR, 2.8-9.7 years). Results: The mean logistic EuroSCORE was 20.9 ± 14.8%: the logistic EuroSCORE of the zone 1 group (23.3 ± 16.1) was significantly higher than that of the zone 2 group (19.3 ± 12.4%, p = 0.045). The operative time and hospital stay of the zone 1 group were significantly longer than those of the zone 2 group. On the other hand, the in-hospital and late outcomes did not differ significantly between the two groups. There were no significant differences in cumulative survival (66.8% vs. 78.0% at 10 years, Log-rank p = 0.074), aorta-related death-free rates (97.6% vs. 99.2% at 10 years, Log-rank p = 0.312), and aortic event-free rates (81.4% vs. 87.9% at 10 years, Log-rank p = 0.257). Conclusions: Zone 1- and 2-landing hybrid TEVAR outcomes were satisfactory. Despite the high procedural difficulty and surgical risk, the outcomes of zone 1-landing hybrid TEVAR were equal to those of zone 2-landing hybrid TEVAR. If the surgical risk is high, zone 1-landing hybrid TEVAR should not be avoided.

Abstract
OBJECTIVES The aim of this study is to evaluate our surgical strategy for acute aortic dissection Stanford A and determine whether it is safe regardless of the experience of the primary surgeon. METHODS Between April 2015 and September 2020, a total of 160 patients who underwent open surgery for type A aortic dissection at Shonan Kamakura General Hospital were reviewed. Data were collected from reviews of computerized medical records. From this study cohort, we retrospectively reviewed the cases of trainee (group T) and experienced primary surgeons (group E). We evaluated rates of 30 day and in-hospital mortality, stroke, aortic reintervention, and mid-term survival for both groups. RESULTS The rates of 30 day and in-hospital mortalities in group T were 5.1 and 7.7%, respectively, whereas those in group E were 4.7 and 4.7%, respectively. One and 3 year survival rates in group T were 88.4 and 87.1% and in group E were 95.3 and 95.3%, respectively (log-rank test, p = 0.11). The 1 year and 3 year rates of freedom from reintervention were 90.9 and 72.8% in group T and 96.8 and 92.7% in group E, respectively (log-rank test, p = 0.29). The permanent neurological dysfunction rate was 8.1% overall, 8.5% in group T, and 7.0% in group E, with no significant difference. CONCLUSIONS Our surgical strategy for acute type A aortic dissection is safe and appropriate regardless of the experience of the primary surgeon.

Abstract
PURPOSE This study aimed to examine the effect of fibrinogen replacement therapy with cryoprecipitate or fibrinogen concentrate on bleeding outcomes and 1-year mortality in patients undergoing thoracic aortic surgery. METHODS We retrospectively studied 439 consecutive patients who underwent thoracic aortic surgery with cardiopulmonary bypass between January 1st, 2010 and December 31st, 2019 and identified patients who received cryoprecipitate or fibrinogen concentrate (the fibrinogen replacement group) and those who did not (the control group). Multivariate analyses were performed to examine the associations of fibrinogen replacement therapy with perioperative major bleeding (i.e., excessive hemorrhage or blood transfusion), re-exploration for bleeding, and 1-year mortality. RESULTS There were 285 patients in the fibrinogen replacement group who received 2.2 ± 1.0 g of concentrated fibrinogen amount and 154 patients in the control group. The incidence of major bleeding in the fibrinogen replacement group was less than that in the control group in patients with fibrinogen level < 150 mg/dL during cardiopulmonary bypass (49.7% versus 74.6%, p = 0.0007, multivariate odds ratio; 0.33, 95% confidence intervals; 0.12-0.91, p = 0.03), but not in patients with fibrinogen level ≥ 150 mg/dL (25.0% versus 29.6%, p = 0.51). No significant difference was found in re-exploration for bleeding (1.0% versus 1.3%, p = 1.00) or 1-year mortality (10.4% versus 5.3%, multivariate Cox proportional-hazard ratio; 1.03, 95% confidence intervals; 0.82-1.31, p = 0.74) between the fibrinogen replacement group and the control group. CONCLUSIONS The results of this study indicate that 2-3 g of fibrinogen replacement reduces the incidence of major bleeding in patients with hypofibrinogenemia during cardiopulmonary bypass in thoracic aortic surgery.

Abstract
Acute type A aortic dissection (ATAAD) is a life-threatening disease, which often causes cardiac tamponade, rupture, and malperfusion. ATAAD is associated with a high hospital mortality rate. Open aortic surgery for ATAAD is always required to save the patient, particularly elderly patients. Tear-oriented surgery is recommended as the frontline treatment for ATAAD, and hemiarch replacement (HAR) is sufficient because the primary entry is often observed in the ascending aorta (60%-70%). However, HAR has some drawbacks, such as new creation of an anastomotic entry and unfavorable distal aortic remodeling during long-term follow-up. Although total arch replacement (TAR) is a demanding procedure, it is another useful option for ATAAD. Proper patient selection for TAR is controversial. Standardized procedure for TAR, including the optimal brain protection methods and the use of excellent sealed vascular prosthetic grafts, has been established over the past decades. Therefore, TAR is increasingly being selected for HAR in patients who are young or have enlarged aortic arch, severely dissected supra-aortic arch vessels, or hereditary thoracic aortic disorders. The emerging technology of commercially available frozen elephant trunk accelerated the application of TAR, facilitates distal anastomosis, and improves distal aortic remodeling. Although further evidence is required, TAR could be the best choice for HAR for selected patients. Currently, appropriate selection of the surgical technique is important to maximize the benefits of open surgery for ATAAD.

Abstract
Background: Zone 0 landing thoracic endovascular aortic repair (TEVAR) for the treatment of aortic arch diseases has become a topic of interest. This study aimed to verify whether branced TEVAR (bTEVAR) is an effective and a more minimally invasive treatment by comparing the outcomes of bTEVAR and hybrid TEVAR (hTEVAR) in landing zone 0. Methods: This retrospective, single-center, observational cohort study included 54 patients (bTEVAR, n = 25; hTEVAR, n = 29; median age, 78 years; median follow-up period, 5.4 years) from October 2012 to June 2018. The logistic Euro-SCORE was significantly higher in the bTEVAR group than in the hTEVAR group (38% vs. 21%, p < 0.001). Results: There was no significant difference the in-hospital mortality between the bTEVAR and hTEVAR groups (0% vs. 3.4%, p = 1.00). The operative time (220 vs. 279 min, p < 0.001) and length of hospital stay (12 vs. 17 days, p = 0.013) were significantly shorter in the bTEVAR group than in the hTEVAR group. The 7-year free rates of aorta-related deaths (bTEVAR [95.5%] vs. hTEVAR [86.9%], Log-rankp = 0.390) and aortic reintervention (bTEVAR [86.3%] vs. hTEVAR [86.9%], Log-rankp = 0.638) were not significantly different. Conclusions: The early and mid-term outcomes in both groups were satisfactory. bTEVAR might be superior to hTEVAR in that it is less invasive. Therefore, bTEVAR may be considered an effective and a more minimally invasive treatment for high-risk patients.

Trends in thoracic aortic aneurysm hospital admissions, interventions and mortality in England between 1998 to 2020: An observational study. Eur J Vasc Endovasc Surg 2022; 64:340-348. [PMID: 35842176 DOI: 10.1016/j.ejvs.2022.07.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 06/01/2022] [Accepted: 07/10/2022] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To assess trends in thoracic aortic aneurysm (TAA) hospital admissions, interventions, and aneurysm-related mortality (ARM) in England and examine the impact of endovascular repair on mortality for the years 1998 to 2020. METHODS Hospital admission and operative approach (thoracic endovascular aortic repair, TEVAR or open surgical repair, OSR) using Hospital Episodes Statistics (HES), and ARM data from the Office for National Statistics for England (ONS) standardised to the 2013 European Standard Population were analysed using linear regression and Joinpoint regression analyses. ARM was compared between the pre-endovascular era (1998-2008) and the endovascular era (2009-2019). RESULTS A rising trend in in-hospital admission incidence was observed, mainly due non-ruptured admissions (4.11 per 100,000 in 1998 [95% CI 3.71 to 4.50 per 100,000] to 12.61 per 100,000 in 2020 [95% CI 12.00 to 13.21 per 100,000] in 2020; r2 = 0.98; p < .001). Operative interventions increased mainly due to an increase in TEVAR (2.15 per 100,000 [95% CI 1.91 to 2.41 per 100,000] in 2020 vs 0.26 per 100,000 [95% CI 0.16 to 0.36 per 100,000] in 2006; r2 = 0.90; p < .001). Reductions in ARM from TAA were observed for males and females, irrespective of age and rupture status. The greatest reduction in ARM in the endovascular era was observed in females > 80 years, with ruptured disease 15.26 deaths per 100,000 versus 9.50 deaths per 100,000, p < .0001). CONCLUSION A significant increase in hospital admissions for non-ruptured TAA was observed in the last 23 years in England, paralleled by a shift towards endovascular repair, and significant declining trends in ARM irrespective of gender and age. The significant reductions in ASDR from ruptured and non-ruptured TAA in the endovascular era, particularly for females >80 years with ruptured disease affirm the positive impact of an endovascular approach to TAA.

[PMID: 35434259 PMCID: PMC9011164 DOI: 10.1016/j.ijcha.2022.101030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 04/05/2022] [Accepted: 04/06/2022] [Indexed: 11/23/2022]
Abstract
HD patients underwent SAVR-BP for AS (hospital mortality, 8.8%; 5-year mortality, 42.1%). Preoperative risk factors for 5-year mortality: age, hyperlipidemia, LVDd, LVDs, and Japan SCORE. Postoperative risk factors for 5-year mortality: length of ICU stay, and albumin level at discharge.
Background Limited studies have assessed the factors affecting prognosis in hemodialysis (HD) patients who undergo surgical aortic valve replacement with a bioprostheses (SAVR-BP). This study aimed to evaluate the outcomes of HD patients who had undergone SAVR-BP for aortic stenosis (AS) and identify the risk factors for mortality. Methods This retrospective study included 57 HD patients who had undergone SAVR-BP for AS between July 2009 and December 2020. Multivariate logistic regression was used to predict factors associated with mid-term outcomes and death or survival. Kaplan − Meier curves were also generated for mid-term survival. Results The in-hospital mortality rate was 8.8%, and the 5-year mortality rate was 42.1%. The independent predictors of 5-year mortality were preoperative age (hazard ratio [HR], 1.57; 95% confidence interval [CI], 1.175–2.083, p = 0.002), hyperlipidemia (HR, 0.02; 95% CI, 0.002–0.297, p = 0.004), left ventricular diastolic diameter (HR, 1.74; 95% CI, 1.142–2.649, p = 0.010), left ventricular systolic diameter (HR, 0.61; 95% CI, 0.392–0.939, p = 0.025), and Japan SCORE (HR, 1.28; 95% CI, 1.052–1.563, p = 0.014). The postoperative predictors included intensive care unit stay (HR, 1.11; 95% CI, 1.035–1.194, p = 0.004) and albumin level (HR, 0.38; 95% CI, 0.196–0.725, p = 0.003). Conclusions The 5-year prognosis of HD patients undergoing SAVR may be improved by early diagnosis (before the occurrence of LV hypertrophy/enlargement) and nutritional management with oral intake to alleviate postoperative hypoalbuminemia. Registration number of clinical studies: UMIN000047410.

Abstract
Although cardiac and aortic operations have been successfully performed for more than 60 years, the risk of neurologic complications remains high. In particular, the rate of stroke with cardiac operations continues to be significant in the 1%-5% range. Similarly, the risk of stroke with aortic operations remains in the range of 7%-10% despite many years of improving techniques. Because of this persistently high risk, the use of intra-operative neurophysiologic monitoring (IONM) has the potential of improving outcomes. This chapter provides an overview of cardiac/aortic arch procedures from the neurophysiologic standpoint and discusses the roles of different monitoring modalities in detecting injury.

Abstract
OBJECTIVE To investigate the outcomes and effectiveness of different types of hybrid aortic arch repair for aortic dissection involving the aortic arch. METHODS From 2013 to 2020, 168 patients underwent hybrid aortic arch repair for dissection involving the aortic arch. We collected data from our electronic medical records, including the presenting pathology, perioperative details, and postoperative outcomes. We included the following types of hybrid aortic arch repair: classic type I, type II, and type III hybrid aortic arch repair, as well as the new type IV hybrid aortic repair. We defined type IV hybrid aortic arch repair as revascularization of supra-aortic branches through extra-anatomy bypass without sternotomy, followed by stent-graft placement. RESULTS There were 23, 82, and 63 patients who underwent type I, type II, and type IV hybrid aortic arch repair, respectively. There were no type III hybrid aortic repairs performed. Forty-nine cases were performed urgently. The technical success rate was 99.4%. The early mortality rates of the total group, type I group, type II group, and type IV group were 6.5%, 4.3%, 8.5%, and 4.8%, respectively. Postoperative complications mainly included tracheotomy (8.9%), stroke (6%), wound infection (4.2%), renal insufficiency (8.9%), and endoleak (7.7%). With a mean follow-up of 45.1±28.5 months, the total 1-year and 5-year actual survival rates were 93.5% and 89.0%, respectively. At 6 months, the aortic diameter at the level of the diaphragm decreased significantly (30.8±4.9 mm vs 28.5±6.3 mm, p=0.012), and the rate of thrombosis of the false lumen at the level of pulmonary bifurcation and diaphragm were 95.7% and 83.1%. Ten patients underwent reintervention of the aorta, including 7 endovascular reinterventions, 2 total thoracoabdominal aortic aneurysm repairs, and 1 open total arch replacement. For the total group, the free from aorta reintervention rate at 5 years was 91.4%. CONCLUSION Our results with hybrid aortic arch repair for aortic dissection involving the aortic arch are acceptable. The hybrid aortic arch repair could promote thrombosis of the distal false lumen while excluding intimal tears in the aortic arch.

Abstract
INTRODUCTION Since the approval, the TEVAR is widely used for the repair of thoracic aortic aneurysm. However, the long-term mortality and re-intervention rates compared to OSR are unclear. We aimed to compare the effectiveness of the thoracic endovascular aortic repair (TEVAR) with open surgical repair (OSR) specifically for thoracic aortic aneurysms. EVIDENCE ACQUISITION We conducted a comprehensive search in MEDLINE, PubMed, EMBASE, CINAHL, PROSPERO, Centre for Reviews and Dissemination, and the Cochrane Library up to November 2020. The main outcomes were early mortality, mid-to-long-term survival, and re-intervention. The quality of the evidence was assessed using the GRADE methodology. All analyses were performed using RevMan with the random effect model and Comprehensive Meta-Analysis software. EVIDENCE SYNTHESIS One systematic review and 15 individual studies were included. Pooled analysis showed that 30-day mortality, stroke, renal failure, and pulmonary complications were significantly lower in TEVAR vs. open surgery. The pooled rate of re-intervention significantly favored the OSR. The long-term survival and mortality favored TEVAR and OSR in one and two studies, respectively, but was non-significant in 7 analyzes. CONCLUSIONS Early clinical outcomes including the 30-day mortality, stroke, renal failure, and pulmonary complications significantly favored the TEVAR. However, the mid-to-long-term re-intervention rate favored the OSR and long-term survival was inconsistent among the studies. The quality of evidence was very low. More studies with longer follow-ups are needed. The use of TEVAR should be decided by taking into account other factors including patient characteristics and preferences, cost, and surgeon expertise.

Abstract
OBJECTIVE We performed a multicenter prospective comparative study to determine the impact of a Japanese frozen elephant trunk device on total arch replacement compared with conventional repair without it. METHODS Between 2016 and 2019, a total of 684 patients (frozen elephant trunk procedure; n = 369; conventional repair, n = 315) from 41 institutions were enrolled. The 2 procedures were selected according to each center's strategy. RESULTS The frozen elephant trunk procedure was applied more for aortic dissection, whereas the conventional repairs were predominantly performed for aneurysms. In the former, only hypothermic circulatory arrest time was reduced among the intraoperative parameters. Although there were no differences in the 30-day and in-hospital mortality rates (0.8% and 1.6%, respectively, for the frozen elephant trunk procedure vs 0.3% and 0.6%, respectively, for conventional repair), the neurologic complication rates were significantly higher in stroke (5.7% vs 2.2%; P = .022) and paraplegia (1.6% vs 0%; P = .023). In the propensity score matching analyses using 11 variables, statistical significance disappeared in the differences for mortality and neurologic morbidity (stroke and paraplegia/paraparesis) rates of 194 patients of each group, although they were still higher for the frozen elephant trunk procedure. CONCLUSIONS The early outcomes of total arch replacement with the frozen elephant trunk procedure were acceptable despite its higher prevalence of emergency or redo surgery, which was comparable to that of the conventional repair. This procedure had higher rates of spinal cord injury than the conventional repair, which is a disadvantage of this approach.

Abstract
AIM We aimed to analyze the current treatment status of thoracic/thoracoabdominal aortic diseases in Japan. METHODS Using the Japan Cardiovascular Surgery Database, the number of cases, operative mortality, and major morbidities (stroke, renal failure, pneumonia, paraplegia) of thoracic and thoracoabdominal aortic surgery in 2017 and 2018 were analyzed by surgical site (root-ascending, arch, descending, thoracoabdominal aorta), surgical procedure, and age group. RESULTS The total number of cases was 39,391 (50.1% aortic dissections, 49.9% non-dissections). The number of cases was highest in patients aged in their 70s. In elderly patients, the rates of root replacement (particularly valve-sparing procedures) in the root-ascending aorta and open-chest surgery in the arch and the descending and thoracoabdominal aorta were decreased. The outcome by procedure analysis showed the lowest mortality and morbidity rates for valve-sparing in the root-ascending region, and lower mortality and morbidity (cerebral infarction, renal failure, pneumonia) in non-open-chest procedures (thoracic endovascular aortic repair with/without branch reconstruction) than in open-chest procedures in the arch, descending, and thoracoabdominal regions. With regards to age, operative mortality in patients aged 80 years or older was significantly higher than in those under 80 years of age for all surgical procedures in the root-ascending, arch, and descending regions. CONCLUSIONS Thoracic and thoracoabdominal aortic surgery in Japan was most commonly performed in elderly patients in their 70s, with a good overall mortality rate of 5.3%. Mortality and postoperative morbidity rates in patients aged 80 years or older were still high. In the future, further improvements in surgical outcomes are needed.

Abstract
BACKGROUND The aim of the present study was to evaluate early results of thoracic endovascular aortic repair (TEVAR) using the Valiant Navion™ stent graft in a "real-world" scenario. METHODS All patients who underwent TEVAR with the Valiant Navion™ endograft between November 2018 and November 2019 were included in this retrospective multicenter study (six European centers). The primary endpoints were technical success, incidence of major adverse events (MAEs), access failure, deployment failure, deployment accuracy, and rate of intraoperative endoleaks (ELs). RESULTS One hundred-sixteen patients with varying thoracic aortic diseases were included. Eighteen patients (15.5%) were treated for an off-label condition. The technical success rate was 100%, without any access or deployment failures. The proximal and distal deployment accuracy rates were 99.1% and 97.4%, respectively. There were no intraoperative MAEs, including death. Two (1.7%) type Ib ELs were detected at the first postoperative CTA, all of which were in off-label procedures and related to the short length of the sealing neck. No type III ELs were detected. The median hospitalization time was 8 days (IQR 4-12), including a median intensive care unit stay of 1 day (IQR 1-2). The in-hospital mortality rate was 4.3%. At a median follow-up time of 98 days (IQR 39-187), there were no aortic-related mortalities or new onset of endoleaks. CONCLUSION Our initial experience with the Valiant Navion™ endograft in a wide variety of aortic diseases showed safe early outcomes, especially for on-label procedures.

Abstract
OBJECTIVE Thoracic endovascular aortic repair (TEVAR) has become the most common surgical procedure for treatment of descending thoracic aortic pathology. Cervical debranching in the form of carotid-subclavian bypass or transposition (CSBT) and carotid-carotid bypass (CCB) has enabled the use of TEVAR for the treatment of more complex anatomy involving the arch. The present study examined the effects of concomitant cervical bypass on the perioperative outcomes of TEVAR. METHODS The American College of Surgeons National Surgical Quality Improvement Program files (2005-2017) were reviewed. Using the Current Procedural Terminology codes, all patients who had undergone TEVAR were identified and were divided into three groups: TEVAR, TEVAR with one bypass (CSBT or CCB), and TEVAR with two bypasses (CSBT and CCB). The patient characteristics and perioperative outcomes of the three groups were compared. Multivariable analysis was performed to determine the factors associated with mortality. RESULTS A total of 3281 patients had undergone TEVAR and 10% had also undergone one or more debranching procedure (one bypass, 9%; two bypasses, 1%). The frequency of debranching had increased from 3.4% to 10.9% (P = .01) during the study period. Significant differences were found among the three groups in age, sex, smoking history, urgency of surgery, and anesthesia technique. The patients who had undergone TEVAR with cervical debranching had had significantly greater morbidity, longer operating times, and longer hospital stays compared with those who had undergone TEVAR alone. The mortality of TEVAR with two bypasses (22.6%) was significantly greater than that of TEVAR alone (7.5%) and TEVAR with one bypass (6.8%; P < .01). The total morbidity (30.9% vs 35.1% vs 67.7%; P < .001) and stroke rate (3% vs 7.5% vs 12.9%; P < .0001) increased with the increasing number of bypasses. A subgroup analysis of patients who had undergone TEVAR with one bypass showed no significant differences in mortality between TEVAR plus CSBT (6.6%) vs TEVAR plus CCB (8.8%; P = .63). Multivariable analysis showed that TEVAR with two bypasses was associated with significantly increased mortality compared with TEVAR alone (odds ratio [OR], 4.33; 95% confidence interval [CI], 1.75-10.73) and TEVAR with one bypass (OR, 3.44; 95% CI, 1.24-9.51). Older age (OR, 1.74; 95% CI, 1.42-2.13), dependent functional status (OR, 1.48; 1.00-2.19), dialysis (OR, 2.61; 95% CI, 1.57-4.33), and emergent status (OR, 3.66; 95% CI, 2.73-4.90) were also associated with mortality. CONCLUSIONS TEVAR with concomitant cervical debranching has been increasingly used to treat complex aortic pathology but is associated with significantly worse outcomes than TEVAR alone. As advanced endovascular technology to treat the aortic arch emerges, the outcomes of open surgical debranching in the present study constitute an important benchmark for comparison.

Abstract
The patient was a 76-year-old woman with an atypical descending thoracic aortic aneurysm due to a highly tortuous descending aorta. The surgical approach in this case required special consideration because of the aneurysm’s location. The main body of the aneurysm was in the right thoracic cavity. Descending thoracic aorta replacement with a prosthetic graft and aneurysmal total exclusion were performed through a left curvilinear thoracoabdominal incision. The patient’s postoperative course was uneventful. Surgical exclusion of a thoracic aortic aneurysm may be a useful technique in this special situation. Postoperative follow-up is needed to prevent early and late complications.

Abstract
Cardiovascular diseases (CVDs) are one of the foremost causes of high morbidity and mortality globally. Preventive, diagnostic, and treatment measures available for CVDs are not very useful, which demands promising alternative methods. Nanoscience and nanotechnology open a new window in the area of CVDs with an opportunity to achieve effective treatment, better prognosis, and less adverse effects on non-target tissues. The application of nanoparticles and nanocarriers in the area of cardiology has gathered much attention due to the properties such as passive and active targeting to the cardiac tissues, improved target specificity, and sensitivity. It has reported that more than 50% of CVDs can be treated effectively through the use of nanotechnology. The main goal of this review is to explore the recent advancements in nanoparticle-based cardiovascular drug carriers. This review also summarizes the difficulties associated with the conventional treatment modalities in comparison to the nanomedicine for CVDs.

Quality improvement in cardiovascular surgery: results of a surgical quality improvement programme using a nationwide clinical database and database-driven site visits in Japan. BMJ Qual Saf 2019; 29:560-568. [DOI: 10.1136/bmjqs-2019-009955] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Revised: 10/23/2019] [Accepted: 10/26/2019] [Indexed: 01/03/2023]
Abstract
BackgroundIn 2015, an academic-led surgical quality improvement (QI) programme was initiated in Japan to use database information entered from 2013 to 2014 to identify institutions needing improvement, to which cardiovascular surgery experts were sent for site visits. Here, posthoc analyses were used to estimate the effectiveness of the QI programme in reducing surgical mortality (30-day and in-hospital mortality).MethodsPatients were selected from the Japan Cardiovascular Surgery Database, which includes almost all cardiovascular surgeries in Japan, if they underwent isolated coronary artery bypass graft (CABG), valve or thoracic aortic surgery from 2013 to 2016. Difference-in-difference methods based on a generalised estimating equation logistic regression model were used for pre-post comparison after adjustment for patient-level expected surgical mortality.ResultsIn total, 238 778 patients (10 172 deaths) from 590 hospitals, including 3556 patients seen at 10 hospitals with site visits, were included from January 2013 to December 2016. Preprogramme, the crude surgical mortality for site visit and non-site visit institutions was 9.0% and 2.7%, respectively, for CABG surgery, 10.7% and 4.0%, respectively, for valve surgery and 20.7% and 7.5%, respectively, for aortic surgery. Postprogramme, moderate improvement was observed at site visit hospitals (3.6%, 9.6% and 18.8%, respectively). A difference-in-difference estimator showed significant improvement in CABG (0.29 (95% CI 0.15 to 0.54), p<0.001) and valve surgery (0.74 (0.55 to 1.00); p=0.047). Improvement was observed within 1 year for CABG surgery but was delayed for valve and aortic surgery. During the programme, institutions did not refrain from surgery.ConclusionsCombining traditional site visits with modern database methodologies effectively improved surgical mortality in Japan. These universal methods could be applied via a similar approach to contribute to achieving QI in surgery for many other procedures worldwide.
