[Outcomes of Modified Bentall Procedure with French Cuff Technique].

BACKGROUND: We evaluated early and mid-term outcomes of modified Bentall procedure with French cuff technique for aortic root disease. METHODS: Between 2017 and 2024, 45 patients underwent modified Bentall procedure with French cuff technique. We excluded patients who had cardiopulmonary resuscitation. The mean age was 64.8± 14.0 years, and 35 patients were male( 77.8%). The mean predicted operative mortality rate according to JapanSCORE 2 was 11.2%. RESULTS: No patients had any trouble with bleeding from the aortic root. Hospital mortality was 2.2%, as one patient died due to a fungal infection. Twelve patients( 26.7%) experienced complications during hospitalization. The 3- and 5-year overall survival rates were 97.7% and 88.0%, respectively. Freedom from reoperation was 93.7% and 93.7% at 3 and 5 years, respectively. One patient underwent re-aortic valve replacement due to a stuck valve, and one underwent re-Bentall due to a seroma. There were no pseudoaneurysm formations of the aortic root and coronary ostia during the followed-up. CONCLUSIONS: The modified Bentall procedure with French cuff technique may be a useful technique with good outcomes.

Aortomitral angle affects cardiovascular events after mitral valve repair for atrial functional mitral regurgitation.

PURPOSE: This study aimed to elucidate the geometric parameters of the aortomitral (AM) complex affecting postoperative cardiovascular events (CVEs) in patients with atrial functional mitral regurgitation (MR). METHODS: From October 2008 to August 2018, we performed mitral and tricuspid valve repairs in 58 patients with atrial functional MR. We examined the determinants of CVEs using preoperative and postoperative echocardiographic data. Furthermore, we analyzed the effect of left atrial (LA) plication on AM geometries after surgery. The follow-up period ranged from 56 to 3283 days (median, 1073 days). RESULTS: All patients underwent mitral and tricuspid annuloplasty. Seventeen patients (29%) underwent additional LA plication. The AM angle was narrowed after surgery in patients with CVEs (115° ± 6.8° to 106° ± 4.2°, p = .00336), whereas it widened in patients without CVEs (115° ± 7.4° to 118° ± 8.4°, p = .0278). The postoperative AM angle was an independent predictor of postoperative CVEs (p = .000829). LA plication was not a predictor of CVEs; however, it was a predictor of the obtuse postoperative AM angle (p = .0071). CONCLUSIONS: Our results suggest that a narrow postoperative AM angle is an independent predictor of postoperative CVEs. Additional LA plication reduces the sharpening of the AM angle, which may prevent CVEs after mitral valve repair for atrial functional MR.

Corynebacterium jeikeium-induced infective endocarditis and perivalvular abscess diagnosed by 16S ribosomal RNA sequence analysis: A case report.

INTRODUCTION: Corynebacterium jeikeium normally presents on human skin, and it is often judged as contamination when it is cultured from blood. C. jeikeium can cause infective endocarditis, especially, that associated with cardiac surgery and prosthetic valvular endocarditis. CASE REPORT: A 66-year-old Japanese male patient was diagnosed with C. jeikeium-induced infective endocarditis (IE) and perivalvular abscess after a coronary artery bypass grafting and aortic valve replacement with bioprosthesis; pyogenic spondylodiscitis was also observed. Patch repair for aortic valve annulus and re-Bentall procedure with bioprosthesis was performed for IE and perivalvular abscess. The causative bacterium was confirmed as C. jeikeium on 16S ribosomal RNA sequencing of surgical sample and positive blood culture. The patient underwent six weeks of intravenous antibacterial treatment with vancomycin and an additional two weeks of oral treatment with linezolid, following which, his condition improved. Corynebacterium jeikeium can cause infective endocarditis and perivalvular abscess, which is a more severe condition than IE. CONCLUSION: 16S ribosomal RNA sequencing is useful in diagnosing bacterial species that can cause contamination, such as Corynebacterium spp.

Loop technique for degenerative mitral regurgitation due to extended prolapse.

PURPOSE: Our study aims to examine the midterm outcomes of the loop technique for extended mitral valve (MV) prolapse patients. METHODS: From October 2008 to August 2020, we performed MV repairs in 407 patients with severe mitral regurgitation (MR). Follow-up ranged in duration from 287 to 2899 days (median, 872 days). The prolapse extensiveness (p-score) was determined based on the ratio of prolapsing segment's areas to whole area. We divided the whole MV into 10 segments (A1, A2 medial, A2 lateral, A3, P1, P2 medial, P2 lateral, P3, AC, and PC). Patients were categorized into three groups according to the p-score: simple (0.1-0.2), intermediate (0.3-0.4), and extensive (0.5-0.9). RESULTS: All patients underwent MV repair with the loop technique. The rates of freedom from significant (moderate to severe or severe) MR at 5 and 7 years after surgery were 91% and 91%, respectively. There were 252, 115, and 40 patients in simple group, intermediate group, and extensive group, respectively. The following were significantly increased in extended group: Barlow disease (23/40 patients, p < .001), the number of loops (p for trend < .0001), and the technique score (p for trend < .0001). The rates of freedom from significant MR at 7 years after surgery were 92% in simple group, 87% in intermediate group, and 94% in extended group, respectively (p = .995). Receiver-operating characteristic curves showed a postoperative mild MR with a sensitivity of 86% and a specificity of 68% for predicting significant MR recurrence. CONCLUSIONS: MV repair using the loop technique was useful even in groups with extended prolapse.

Pulmonary Valvuloplasty by Autologous Pericardium in a Patient with Active Infectious Endocarditis and Osler's Disease.

Osler's disease is a rare condition of autosomal dominant inheritance characterized by bleeding and telangiectasia of the skin and mucosal membranes. A few reports exist of open-heart surgery in patients with Osler's disease. Here, the case is presented of a successful pulmonary valvuloplasty using autologous pericardium to treat active infectious endocarditis of the pulmonary valve in a patient with Osler's disease. Such patients are at higher risk of bacteremia because of their chronic nasal bleeding or pulmonary arteriovenous fistula. In patients with Osler's disease, valuvloplasty using autologous pericardium is considered effective for preventing the later recurrence of IE.

Long-term outcomes of mitral valve repair with the Duran flexible ring.

BACKGROUND: Mitral annuloplasty is a reliable mitral valve repair technique. There are two types of annuloplasy rings: the rigid ring and the flexible ring. This study sought to examine the long-term results of mitral valve repair using a Duran flexible ring. METHODS: We retrospectively reviewed 226 patients who underwent primary mitral valve repair using the Duran flexible ring for mitral regurgitation between September 1994 and March 2003. Patients' mean age was 56.7 years, and 39% were female. The mean follow-up was 10.6 years (0.04 ∼ 18.3), and echocardiographic follow-up was 83.3% complete. RESULTS: There were three early and 25 late deaths. Survival was 89.3 ± 2.2 for 10 years, and 83.5 ± 3.2% for 15 years. The 10- and 15-year freedom from reoperation on the mitral valve were 96.4 ± 1.4 and 95.3 ± 1.7%, respectively. The 10- and 15-year freedom from moderate or severe mitral regurgitation were 92.5 ± 2.2 and 73.7 ± 7.1%, respectively. Cox regression analysis revealed that age, male gender, and isolated anterior leaflet prolapse were predictive of recurrent moderate or severe mitral regurgitation. CONCLUSIONS: Mitral valve repair for mitral regurgitation using a flexible Duran ring is safe and durable for more than 10 years.

[Successful treatment of Candida albicans mediastinitis after open-heart surgery using vacuum-assisted closure device].

An 82-year-old man suffered from Candida albicans mediastinitis following emergency aortic valve replacement. After repeated debridement of the anterior portion of the mediastinum, we applied a vacuum assisted closure device with UrgoTul Absorb placed on the right ventricle. Despite relatively short-term application of this device, mediastinitis was cured in combination with transposition of the great omentum.

Three-dimensional computed tomography analysis of the mitral annulus for mitral annuloplasty in 100 cases of robotic mitral valve repair.

Objectives: This study aimed to evaluate the efficacy of preoperative computed tomography in assessing mitral annulus anatomy and the posterior annular plication rate in mitral valve repair with annuloplasty. Methods: From July 2018 to August 2023, we performed robotic mitral valve repair with ring annuloplasty using a semi-rigid ring in 100 patients. Preoperative anatomical assessment of the mitral annulus was conducted by three-dimensional computed tomography. The ring size was selected based on the perioperative commissure-to-commissure length or the anterior leaflet area. Results: The mean commissure-to-commissure length, posterior mitral annular length, and minimum distance between the left circumflex artery and mitral annulus values were 31, 109, and 3.8 mm, respectively. No postoperative left circumflex artery injury or ring detachment was recorded. The mean plication rate (length of the posterior side of the prosthetic ring/posterior annular length) was 0.68, and it did not differ among each prosthetic ring size. The posterior plication rate (duplicate ring size 19.4) was a factor influencing the postoperative transmitral mean pressure gradient of 5 mmHg or higher. Freedom from moderate or severe mitral regurgitation was not different between the two groups above and below the posterior plication rate × ring size of 19.4 (p = 0.73), with an event-free rate of 97% vs. 96% in 3 years, respectively. Conclusions: Preoperative evaluation of the mitral annular anatomy is useful for safe mitral valve repair with ring annuloplasty. Determining ring size by focusing on the posterior annular plication rate may be a new method for ring size selection.

Additional left atrial plication improves postoperative cardiovascular events in atrial functional mitral regurgitation.

Background: Left atrial (LA) plication is a procedure used to correct an LA that expands posteriorly due to remodeling. This study aimed to determine the efficacy of additional LA plication in reducing postoperative cardiovascular events (CVEs) after mitral valve (MV) repair in atrial functional mitral regurgitation (MR) patients. Methods: Between October 2008 and August 2023, MV repair with or without LA plication in 74 patients was studied. This study examined the efficacy of concomitant LA plication during MV repair. Results: All patients underwent mitral annuloplasty. Of these, 26 underwent additional LA plication. In the mid-term periods, protruding posterior LA length in patients with LA plication was shorter than those without LA plication (2.8±0.49 vs. 3.3±0.72 cm, P=0.01). The percentage change in aortomitral angle from preoperative to mid-term periods in patients with LA plication was bigger than those without LA plication (1.04°±0.102° vs. 0.98°±0.084°, P=0.01). Posterior leaflet coaptation angle in patients with LA plication was smaller than those without LA plication (42°±15° vs. 76°±30°, P<0.001). A postoperative posterior leaflet coaptation angle of 101° had the maximum sum of sensitivity and specificity in predicting postoperative CVEs (96.9% and 76.9%, respectively). Patients with a postoperative posterior leaflet coaptation angle of 101° or higher had a poorer prognosis than those with an angle less than 101°, with an event-free rate of 18% vs. 80% at 7 years after surgery (P<0.0001). Conclusions: Additional LA plication might be useful in reducing postoperative CVEs in atrial functional MR patients.

Delayed traumatic aortic valve perforation after blunt chest trauma.

BACKGROUND: Aortic valve perforation is a rare complication of blunt chest trauma. We report a case of delayed aortic insufficiency presenting several months after trauma. CASE PRESENTATION: A 17-year-old male presented to the emergency department with traumatic brain injuries and blunt chest trauma, but no evidence of cardiac injuries. Three months later, he developed acute heart failure due to severe aortic valve regurgitation with left ventricular dysfunction. A sizable tear in the right coronary cusp caused aortic insufficiency. He was treated successfully by surgical replacement with an aortic bioprosthesis. CONCLUSION: We reported a successful surgical case of valve replacement for delayed aortic valve perforation. Delayed valve perforation should be kept in mind after blunt chest trauma.

Fate of functional tricuspid regurgitation after mitral valve repair for degenerative mitral regurgitation.

BACKGROUND: The issue of whether functional tricuspid regurgitation (TR) should be repaired at the time of mitral valve surgery is controversial, and the long-term durability of tricuspid valve (TV) annuloplasty remains unknown. METHODS AND RESULTS: We retrospectively reviewed 654 patients who underwent mitral valve repair for degenerative mitral regurgitation between 1991 and 2010. Preoperative TR was classed as mild, trivial or absent in 479 (73.2%) patients, moderate in 125 (19.1%) patients and severe in 50 (7.7%) patients. Concomitant TV annuloplasty was performed in 162 patients (24.8%). The mean follow up duration was 7.5±4.9 years. Postoperative transthoracic echocardiography was performed according to a fixed schedule. The long-term survival rate and freedom from re-admission for congestive heart failure were affected by the severity of TR. Although the durability of ring annuloplasty was excellent up to 10 years after surgery, the mean TR grade started to increase after 10 years. Sixteen out of 492 patients who did not undergo TV annuloplasty (3.2%) revealed progression to severe TR. Preoperative atrial fibrillation (odds ratio (OR), 4.85; 95% confidence interval (CI), 1.38-17.1; P=0.014) and preoperative TR grade (OR, 5.16; 95% CI, 1.78-14.9; P=0.003) were predictors for progression to severe TR. CONCLUSIONS: Aggressive treatment with concomitant TV annuloplasty should be advocated in cases with atrial fibrillation and more than moderate TR.

Mechanism of and risk factors for reoperation after mitral valve repair for degenerative mitral regurgitation.

BACKGROUND: We reviewed our 20-year experience of mitral valve (MV) repair for degenerative mitral regurgitation (MR) and analyzed the mechanisms and risk factors of reoperation. METHODS AND RESULTS: Six hundred and fifty-four patients who underwent MV repair for degenerative MR between 1991 and 2010 were retrospectively reviewed. The mean follow-up duration was 7.5 ± 4.9 years. Late echocardiography was obtained at a fixed schedule. Standard procedures for MV repair were resection and suture for posterior prolapse, artificial chordal reconstruction for anterior prolapse and a combination of them for prolapse of both. Ring annuloplasty was performed in most cases. We encountered 2 early and 23 late reoperations. Fifteen (60%) were valve-related failure, 9 (36%) were procedure-related failure and 1 was unknown. Valve-related failure was characterized with recurrence of MR due to new prolapse region and progression of mitral stenosis due to leaflet thickening. For them, reoperation was performed at 7.6 years and 14.3 years after the initial operation, respectively. Multivariate analysis identified preoperative left ventricular diastolic diameter and residual regurgitation at discharge as risk factors for reoperation. CONCLUSIONS: Valve-related failure occurred late due to slow progression of degenerative disease. Long-term follow-up after surgery is mandatory. Given that progression and severity of MR were identified as risk factors for reoperation, early surgical intervention is desirable for degenerative MR.

Flexible Total Ring Annuloplasty With Continuous Wrapping Suture Considering the Anatomy and Histology of the Tricuspid Valve.

OBJECTIVE: About half of tricuspid valves (TVs) have 2 posterior leaflets, and the fibrous tissue of the tricuspid annulus is poor. Considering the anatomy and histology of the TV, we devised a secure ring annuloplasty technique. We herein report the outcomes of our continuous wrapping suture annuloplasty technique using a flexible total ring. METHODS: We used a Tailor™ ring (Abbott, Chicago, IL, USA) as a full ring. The mark on the left side of the ring was fixed to the anteroseptal commissure, and the midpoint of the ring's markers was fixed at the center of the septal leaflet annulus. Using a continuous suture, all stitches were passed around the annuloplasty ring without penetration. One suture from the anteroseptal commissure ran toward the left side and another from the midpoint of the septal leaflet annulus ran toward the right, leading to annuloplasty without TV deformation. RESULTS: Eighty patients underwent TV repair with this technique. The tricuspid regurgitation (TR) score in all patients improved from 1.9 ± 0.7 to 0.8 ± 0.4 (P < 0.001) at 3 years postoperatively. The TR score of TVs with 2 posterior leaflets also improved from 1.9 ± 0.7 to 0.6 ± 0.4 after the operation and was unchanged during follow-up. The median follow-up period was 1.3 (0.5 to 2.0) years, and no patients required TV reoperation. The 3-year survival rate was 93%, and the 3-year rate of freedom from pacemaker implantation was 95%. CONCLUSIONS: The continuous wrapping suture technique using a flexible total ring is a useful procedure without TV deformation even when 2 posterior leaflets are present.

Midterm Results of Mitral Valve Repair Using Loop Technique With Simple Height Reduction of the Large Posterior Leaflet.

OBJECTIVE: Systolic anterior motion (SAM) is one of the most serious problems in mitral valve repair. Height reduction is a key procedure to solve SAM, and there are limited data on the surgical results of height reduction procedure. This study is to assess the effectiveness and midterm results of simple height reduction procedure for SAM in patients with severe mitral regurgitation (MR). METHODS: From 2008 to 2022, 50 patients underwent loop technique with an additional simple height reduction procedure for prevention of SAM. We examined the midterm results of patients with simple height reduction regarding recurrent MR and reoperation. The follow-up period ranged from 171 to 3,816 days (median, 883 days). RESULTS: There were 338 patients (87%) who underwent loop technique without height reduction and 50 patients (13%) who underwent loop technique with height reduction. After the height reduction procedure, SAM was prevented in 44 patients, and 6 patients needed volume loading to suppress SAM. Freedom from recurrence of moderate to severe or severe MR at 1, 3, and 5 years was 98%, 88%, and 88% in the height reduction group versus 98%, 96%, and 94% in the group with loop technique alone (P = 0.074). Receiver operating characteristic curves showed that a systolic dimension of 26 mm had a sensitivity of 75% and a specificity of 83% for predicting SAM after height reduction. CONCLUSIONS: Loop technique with simple height reduction was a simple, secure, and effective procedure to prevent SAM and recurrent significant MR in the midterm periods.

Vascular access site complications after transfemoral transcatheter aortic valve implantation: a comparison of open and percutaneous puncture approaches.

Background: In transfemoral transcatheter aortic valve implantation (TF-TAVI), which approach has lower vascular access site complications between the open puncture (OP) and percutaneous puncture (PP) approaches is still controversial. Moreover, few studies have analyzed risk factors for vascular access site complications in TF-TAVI. This study aimed to compare vascular access site complications between the OP and PP approaches in patients undergoing TF-TAVI and access risk factors for vascular access site complications. Methods: Three hundred fifty-one patients who underwent TF-TAVI via the PP (n=251) and OP (n=100) were retrospectively examined. Results: Incidence of vascular access site complications was 7.0% in the OP group and 8.4% in the PP group (P=0.828). Two deaths from vascular access site complications occurred in the PP group. After performing inverse probability weighting (IPW), regression analysis showed that PP was associated with a significantly higher odds of vascular access site complications [odds ratio =2.033; 95% confidence interval (CI): 1.397-2.958; P<0.001]. Common femoral artery (CFA) depth (hazard ratio =1.04; 95% CI: 1.000-1.070; P=0.045) and sheath/CFA diameter ratio (hazard ratio =971; 95% CI: 22.6-41,700; P<0.001) were independent complication risk factors. In patients with CFA depth ≥35 mm, the incidence of vascular access site complications was higher with PP than OP. Sheath/CFA diameter ratio ≥0.9 was associated with increased risk of vascular injury with both approaches. Conclusions: The incidence of vascular access site complications in patients undergoing TF-TAVI was significantly lower with OP than PP after IPW. OP may be preferable when CFA depth is ≥35 mm. When the sheath/CFA diameter ratio is ≥0.9, approaches other than the TF approach should be considered.

Mitral valve repair with patch augmentation for atrial functional mitral regurgitation complicated with giant left atrium.

OBJECTIVE: We aimed to assess the results of posterior leaflet augmentation with an autologous pericardial patch in atrial functional mitral regurgitation. METHODS: Data of 16 patients with atrial functional mitral regurgitation who underwent posterior leaflet patch augmentation for mitral valve repair were retrospectively analyzed. This procedure was applied to a short posterior leaflet with a height of < 10 mm in P2. The median age was 72.5 [67.8-78.3] years. Preoperative New York Heart Association functional class was II in 7 (43.8%) and III or IV in 9 (56.2%) patients. Mitral regurgitation was moderate in 2 (12.5%) and severe in 14 (87.5%) patients. RESULTS: Operative mortality occurred in 1 (6.2%) patient due to cerebral infarction. One patient required valve replacement because of patch perforation early after operation. Mitral regurgitation was reduced to less than mild in 15 (93.8%) patients and less than trivial in 11 (68.8%) patients (P < 0.01) postoperatively. As for mid-term results, New York Heart Association functional class improved to I or II in 12 (75%) patients (P < 0.01). Two cases of thrombotic complication were observed. Remote recurrent regurgitation occurred in one case due to small patch size. The 3-year free rate of valve-related morbidity and regurgitation recurrence was 65.6% and 87.1%, respectively. The 5-year survival rate was 93.8%. CONCLUSIONS: Pericardial patch augmentation in atrial functional mitral regurgitation leads to good survival and mitral regurgitation recurrence-free rates. Steady anticoagulation and the use of larger patches would be necessary to reduce thrombotic complications and recurrent MR.

Outcomes of loop technique with ring annuloplasty: a > 10-year experience.

OBJECTIVE: We assessed the long-term outcomes of the loop technique with ring annuloplasty for mitral regurgitation from our > 10-year experience. METHODS: We retrospectively reviewed 362 patients who underwent the loop technique with ring annuloplasty via median sternotomy or right mini-thoracotomy for mitral regurgitation. The median follow-up duration was 4.1 years (interquartile range 2.3-5.8 years). RESULTS: This study involved 147 women and 215 men (median age, 66.5 years). Mitral regurgitation was caused by Barlow's disease in 27 patients. Seven patients required reoperations (recurrent regurgitation caused by technical issues, n = 3; progression of degenerative disease, n = 4). The 5- and 10-year cumulative incidences of reoperation considering death as the competing event were 1.4% and 5.4%, respectively. The 5- and 10-year postoperative cumulative incidences of moderate-to-severe recurrent mitral regurgitation were 4.7% and 13.0%, respectively. Residual regurgitation ≥ mild (hazard ratio, 6.99; 95% confidence interval, 1.520-32.12; P = .012) was an independent risk factor for reoperation. The independent risk factors for moderate-to-severe recurrent regurgitation were residual regurgitation ≥ mild (hazard ratio, 9.60; 95% confidence interval, 3.042-30.31; P < .001) and the loop-in-loop technique (hazard ratio, 3.40; 95% confidence interval, 1.058-10.90; P = .040). The median mean pressure gradient was sustained at almost 3.5 mmHg for > 7 years. CONCLUSIONS: The loop technique with ring annuloplasty provided excellent results with good hemodynamics beyond the mid-term. Residual regurgitation ≥ mild and the loop-in-loop technique may not be preferable for durable outcomes.

Patch augmentation vs. valve replacement for patients with atrial functional mitral regurgitation and long-standing atrial fibrillation.

Background: Long-standing atrial fibrillation is associated with atrial functional mitral regurgitation (AFMR) with atriogenic tethering. We compared the outcomes of patch augmentation (PA) and valve replacement (VR) for AFMR. Methods: We retrospectively compared the data of 16 patients who underwent PA for AFMR with the data of 15 patients who underwent VR between 2008 and 2021. Patients with a left ventricular ejection fraction (LVEF) of <50% were excluded. We also performed atrial plication and left appendage closure if the patients had no weak atrial wall that led to severe bleeding. Results: The median age was 72.5 and 76.0 years in the PA and VR groups, respectively. The PA group had a longer cardiopulmonary bypass time (206 vs. 172 min, P=0.012). Although there were no differences in hospital morbidity and mortality between the PA and VR groups, one patient underwent reoperation for patch perforation in the PA group. The overall 3-year survival rate was 93.8% and 100% in the PA and VR groups, respectively (P=0.878). The 3-year rate of freedom from major adverse cardiac events was 75.0% and 53.6% in the PA and VR groups, respectively (P=0.181). Three and six patients were readmitted for congestive heart failure in the PA and VR groups, respectively. Two patients in the PA group developed severe recurrent regurgitation, including one patient who required reoperation. No patients in the VR group required reoperation. The postoperative left atrial volume index (LAVI) was associated with thromboembolic events (P=0.016). Conclusions: PA may achieve comparable outcomes to those of VR for AFMR. Operative procedures should be chosen based on each patient's background. Atrial reduction could be considered to prevent thromboembolic events.

Early outcomes of the Frozenix J-graft with exclusion of the non-stent part at a single center.

Background: The frozen elephant trunk technique is useful in aortic arch repair; however, some adverse events are associated with the Frozenix J-graft. We designed a technique to prevent these adverse events and achieve easy anastomosis (Total Exclusion of the Non-Stent part of Frozenix using an Everting anastomosis [TENSE]), and we assessed the outcomes of this technique in the present study. Methods: From April 2017 to May 2021, 44 patients with aortic arch disease underwent TENSE, in which the proximal stump of the stent part of Frozenix was matched to the distal anastomosis end between the left common carotid and left subclavian arteries. Results: The median age of the patients (35 men, 9 women) was 76.5 years. The predicted mortality and morbidity rates were 10.0% and 40.2%, respectively, according to the JapanSCORE II. Two patients (4.5%) died of aneurysm rupture and interstitial pneumonia, respectively, during hospitalization. Four patients (9.1%) who developed postoperative cerebral infarction had a previous cerebral infarction (P=0.010). No patients developed spinal cord complications or Frozenix kinking. Follow-up computed tomography showed no endoleaks or aneurysmal dilatation, although one patient had possible distal stent graft-induced new entry. Conclusions: Our strategy provided good early outcomes without spinal cord complications or Frozenix kinking in patients with aortic arch disease. Continuous follow-up is needed to avoid missing distal changes.
