ABSTRACT

A 66-year-old man developed exertional dyspnea. The patient had undergone total arch replacement for a dissecting aortic arch aneurysm at the age of 53 and conservative treatment for myocardial infarction at the age of 60. Several imaging studies revealed a giant pseudoaneurysm that likely originated from a true ventricular aneurysm. The pseudoaneurysm severely compressed the right ventricle. Surgery was promptly performed. The patient had a history of cardiac surgery and had exclusively dense pericardium adhesion. Therefore, we incised the pseudoaneurysm and sutured the rupture orifice directly from inside the pseudoaneurysm under rapid pacing. This approach may represent an effective surgical alternative in patients with small rupture orifice and dense adhesions.

ABSTRACT

Fenestrated endovascular repair (FEVAR) can be a treatment option for thoraco-abdominal aneurysm( TAAA), especially in the cases with high surgical risks. Spinal cord ischemic injury( SCI) continues to be the most devastating complication, that has multifactorial etiologies including embolic events and coverage of Adamkiewicz's artery (AKA). Recently, we experienced a case of Crawford III TAAA. The 77 year-old male had multiple comorbidities including recent myocardial infarction, chronic heart failure with reduced ejection fraction, and an end-stage renal disease. A colostomy was located on the left side of the abdomen after the surgical resection of rectal cancer. The AKA was originated from the intercostal artery at the level of the tenth thoracic vertebra( THV), which was intended to be covered by a stent-graft. To reduce the risk of SCI, FEVAR was scheduled in a staged fashion, with the proximal coverage up to the tenth THV and a branch-typed endovascular reconstruction of the celiac artery performed as the first stage treatment. The completion repair was achieved in 4 weeks, with the remaining superior mesenteric and renal arteries successfully stented. Neither SCI nor endoleak was detected periprocedurally.

ABSTRACT

BACKGROUND: We examined whether an aerobic exercise intervention in young women with cold sensitivity symptoms improves sleep quality and decreases cold complaints. Furthermore, we examined the association with increased foot skin temperature (Tsk) before falling asleep and decrease in sensitivity to cold in the brain. METHODS: We recruited 16 female adult volunteers who had cold sensitivity and were not engaged in daily exercise training, and they were divided into an exercise group (EXE) and a control group (CON). EXE was given a 2-week exercise intervention that consisted mainly of walking and jogging. Before and after the intervention, temperature sensation and body temperature parameters were measured just before bedtime; electroencephalogram measurements were taken during sleep; and subjective sleep surveys, including Oguri-Shirakawa-Azumi (OSA) sleep inventory (middle-aged and aged version) and visual analogue scale (VAS), were conducted immediately after waking up. All experiments were performed in the winter season. RESULTS: In EXE, overall and foot warmth and comfort increased (p < 0.05) after the 2-week exercise intervention. The exercise intervention also decreased (p < 0.05) the scores for cold feeling in the fingertips, feet, and toes. In the OSA sleep inventory, factor IV (refreshing) and factor V (sleep length) were increased (p < 0.05) by the exercise intervention. Subjective sleep quality evaluated by VAS increased (p < 0.05) with exercise intervention. The exercise intervention in EXE shortened middle awake time after sleep onset (p < 0.05) and prolonged deep sleep length (p < 0.05). The exercise intervention increased (p < 0.05) alpha-wave power before sleep. In CON, all variables remained unchanged throughout the 2-week control period. CONCLUSION: Short-term aerobic exercise alleviated peripheral extremity cold sensitivity symptoms and improved subjective sleep quality. Our findings suggest that these improvements were not due to increased Tsk at rest before bedtime but to decreased sensitivity to cold in the brain that was expressed as increased alpha activity.

ABSTRACT

BACKGROUND: There is a paucity of data regarding shorter life expectancy after aortic valve replacement (AVR) in patients with severe aortic stenosis (AS). METHODS: Among 3815 patients with severe AS enrolled in the CURRENT AS (Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis) registry, there were 1469 patients (initial AVR: n = 647; conservative strategy: n = 822) with low surgical risk, 1642 patients (initial AVR: n = 433; conservative strategy: n = 1209) with intermediate surgical risk, and 704 patients (initial AVR: n = 117; conservative strategy: n = 587) with high surgical risk. Among 1163 patients who actually underwent surgical AVR as the initial strategy, patients were divided into 4 groups according to age <65 years (n = 185), 65 to 74 (n = 394), 75 to 80 (n = 345), and >80 (n = 239). The expected survival of the general Japanese population was obtained from the Statistics Bureau of Japan. The surgical risk was estimated using The Society of Thoracic Surgery (STS) score. RESULTS: The median follow-up was 3.7 years. The cumulative incidences of all-cause death were significantly lower in the initial AVR strategy than in the initial conservative strategy across the 3 STS groups. Shorter life expectancy after surgical AVR was seen especially in younger patients. The observed mortality in low-risk patients was comparable to the expected mortality across all the age-groups, while intermediate-risk patients aged <75 years, and high-risk patients across all age-groups had higher mortality compared with the expected mortality. CONCLUSIONS: The risk stratification according to age and STS score might be useful to estimate shorter life expectancy after AVR, and these findings have implications for decision making in the choice of surgical or transcatheter AVR.

ABSTRACT

BACKGROUND: The clinical significance of concomitant mitral regurgitation (MR) has not been well addressed in patients with severe aortic stenosis (AS).Methods and Results:We analyzed 3,815 patients from a retrospective multicenter registry of severe AS in Japan (CURRENT AS registry). We compared the clinical outcomes between patients with moderate/severe MR and with none/mild MR according to the initial treatment strategy (initial aortic valve replacement [AVR] or conservative strategy). The primary outcome measure was a composite of aortic valve-related death or heart failure hospitalization. At baseline, moderate/severe MR was present in 227/1,197 (19%) patients with initial AVR strategy and in 536/2,618 (20%) patients with a conservative strategy. The crude cumulative 5-year incidence of the primary outcome measure was significantly higher in patients with moderate/severe MR than in those with none/mild MR, regardless of the initial treatment strategy (25.2% vs. 14.4%, P<0.001 in the initial AVR strategy, and 63.3% vs. 40.7%, P<0.001 in the conservative strategy). After adjusting confounders, moderate/severe MR was not independently associated with higher risk for the primary outcome measure in the initial AVR strategy (hazard ratio [HR] 1.11, 95% confidence interval [CI] 0.67-1.83, P=0.69), and in the conservative strategy (HR 1.13, 95% CI 0.93-1.37, P=0.22). CONCLUSIONS: Concomitant moderate/severe MR was not independently associated with higher risk for the primary outcome measure regardless of the initial treatment strategy.

ABSTRACT

Background Heart failure might be an important determinant in choosing coronary revascularization modalities. There was no previous study evaluating the effect of heart failure on long-term clinical outcomes after percutaneous coronary intervention (PCI) relative to coronary artery bypass grafting (CABG). Methods and Results Among 14 867 consecutive patients undergoing first coronary revascularization with PCI or isolated CABG between January 2011 and December 2013 in the CREDO-Kyoto PCI/CABG registry Cohort-3, we identified the current study population of 3380 patients with three-vessel or left main coronary artery disease, and compared clinical outcomes between PCI and CABG stratified by the subgroup based on the status of heart failure. There were 827 patients with heart failure (PCI: N=511, and CABG: N=316), and 2553 patients without heart failure (PCI: N=1619, and CABG: N=934). In patients with heart failure, the PCI group compared with the CABG group more often had advanced age, severe frailty, acute and severe heart failure, and elevated inflammatory markers. During a median 5.9 years of follow-up, there was a significant interaction between heart failure and the mortality risk of PCI relative to CABG (interaction P=0.009), with excess mortality risk of PCI relative to CABG in patients with heart failure (HR, 1.75; 95% CI, 1.28-2.42; P<0.001) and no excess mortality risk in patients without heart failure (HR, 1.04; 95% CI, 0.80-1.34; P=0.77). Conclusions There was a significant interaction between heart failure and the mortality risk of PCI relative to CABG with excess risk in patients with heart failure and neutral risk in patients without heart failure.

ABSTRACT

Chronic kidney disease (CKD) might be an important determinant in choosing percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). However, there is a scarcity of studies evaluating the effect of CKD on long-term outcomes after PCI relative to CABG in the population including severe CKD. Among 30257 consecutive patients patients who underwent first coronary revascularization with PCI or isolated CABG in the CREDO-Kyoto PCI/CABG registry Cohort-2 (n = 15330) and Cohort-3 (n = 14,927), we identified the current study population of 12,878 patients with multivessel or left main disease, and compared long-term clinical outcomes between PCI and CABG stratified by the subgroups based on the stages of CKD (no CKD: eGFR >=60 ml/min/1.73m2, moderate CKD: 60> eGFR >=30 ml/min/1.73m2, and severe CKD: eGFR <30 ml/min/1.73m2 or dialysis). There were 6,999 patients without CKD (PCI: n = 5,268, and CABG: n = 1,731), 4,427 patients with moderate CKD (PCI: n = 3,226, and CABG: n = 1,201), and 1,452 patients with severe CKD (PCI: n = 989, and CABG: n = 463). During median 5.6 years of follow-up, the excess mortality risk of PCI relative to CABG was significant regardless of the stages of CKD without interaction (no CKD: HR, 1.36; 95%CI, 1.12 to 1.65; p = 0.002, moderate CKD: HR, 1.40; 95%CI, 1.17 to 1.67; p <0.001, and severe CKD: HR, 1.33; 95%CI, 1.09 to 1.62; p = 0.004, Interaction p = 0.83). There were no significant interactions between CKD and the effect of PCI relative to CABG for all the outcome measures evaluated. In conclusion, PCI compared with CABG was associated with significantly higher risk for all-cause death regardless of the stages of CKD without any significant interaction.

ABSTRACT

Long-term safety of percutaneous coronary intervention (PCI) as compared with coronary artery bypass grafting (CABG) is still controversial in patients with unprotected left main coronary artery disease (ULMCAD), and there is a scarcity of real-world data on the comparative long-term clinical outcomes between PCI and CABG for ULMCAD in new-generation drug-eluting stents era. The CREDO-Kyoto PCI/CABG registry Cohort-3 enrolled 14927 consecutive patients undergoing first coronary revascularization with PCI or isolated CABG between January 2011 and December 2013, and we identified 855 patients with ULMCAD (PCI: N = 383 [45%], and CABG: N = 472 [55%]). The primary outcome measure was all-cause death. Median follow-up duration was 5.5 (interquartile range: 3.9 to 6.6) years. The cumulative 5-year incidence of all-cause death was not significantly different between the PCI and CABG groups (21.9% vs 17.6%, Log-rank p = 0.13). After adjusting confounders, the excess risk of PCI relative to CABG remained insignificant for all-cause death (HR, 1.00; 95% CI, 0.68 to 1.47; p = 0.99). There were significant excess risks of PCI relative to CABG for myocardial infarction and any coronary revascularization (HR, 2.07; 95% CI, 1.30 to 3.37; p = 0.002, and HR, 2.96; 95% CI, 1.96 to 4.46; p < 0.001), whereas there was no significant excess risk of PCI relative to CABG for stroke (HR, 0.85; 95% CI, 0.50 to 1.41; p = 0.52). In conclusion, there was no excess long-term mortality risk of PCI relative to CABG, while the excess risks of PCI relative to CABG were significant for myocardial infarction and any coronary revascularization in the present study population reflecting real-world clinical practice in Japan.

ABSTRACT

Before the discovery of penicillin, tertiary syphilis was the most common cause of thoracic aneurysms, but now cardiovascular syphilis is a clinical rarity in developed countries. We report a case of 69-year-old man who presented with sudden onset breathlessness that worsened insidiously for 2 months. Diagnosis of syphilitic aortitis was confirmed by laboratory findings, contrast computed tomography, echocardiography and coronary angiography. The patient underwent successful coronary artery bypass graft, aortic valve replacement and ascending aortic replacement. A high level of suspicion and awareness is needed for the diagnosis of the now rare disease.

ABSTRACT

Ventricular septal rupture (VSR) is a rare but fatal complication after acute myocardial infarction (AMI). However, the mortality in patients with recent VSR and appropriate timing of surgical repair have not been clarified. To examine the background characteristics and mortality of VSR patients as well as the usefulness and appropriate timing of surgery in this patient cohort. Among 3,947 consecutive patients with AMI at our hospital, 39 patients diagnosed with VSR from 2002 to 2020 were included in the analysis. All patients underwent transthoracic echocardiography to confirm VSR on admission. Coronary angiography (CAG) and measurement of pulmonary-systemic flow ratio were performed before emergent surgery. The use of mechanical support devices before or after procedures was considered for all patients who underwent CAG. Basically, we performed emergent or urgent operations to patients who were in a shock state or who needed mechanical support. The final decision of the timing of the operation was made by the cardiac team. Patients' mean age was 76.3 years, and 33.3% of them were males. Most culprit lesions were located in the left anterior ascending artery (81.3%). The mean pulmonary-systemic flow ratio after VSR onset was 3.07 ± 1.98. On admission, 48.7% of patients were in a shock state. Surgical repair was possible in 28 patients at a median of 1 day after admission, with a mortality rate of 25%. Among all patients, the mortality rate was 43.6%. Survivors were significantly younger (71.3 ± 11.3 vs. 82.7 ± 6.2 years, p < 0.01), had higher mean arterial blood pressure (75.6 ± 14.4 vs. 62.8 ± 16.2 mmHg, p = 0.0496) and lower ejection fraction (44.3 ± 11.7% vs. 54.8 ± 7.9%, p = 0.04), and underwent surgical repair more frequently (95.5% vs. 41.2%, p < 0.01) than the non-survivors. In multivariate analysis, younger age (odds ratio [OR] 1.18 95% confidence interval [CI] 1.01-1.38, p = 0.04) and surgical repair (OR 0.04, 95% CI 0.00-0.73, p = 0.03) were significant predictors of survival. In surgical repair cases, time from admission to operation did not differ significantly between survivors and non-survivors. Surgical repair and younger age are predictors of survival in patients with recent VSR, but the timing of surgery was not.

ABSTRACT

An 80-year-old woman with essential thrombocythemia was diagnosed with severe mitral regurgitation and moderate tricuspid regurgitation. Preoperatively, she had been treated with hydroxycarbamide and low-dose aspirin since her platelet count was high( 96.2×104/µl). After the platelet count was reduced to 46.2×104/µl, she underwent mitral valve repair and tricuspid valve annuloplasty. Atypical heparin resistance was noted intraoperatively. After initial heparin infusion, the activated clotting time(ACT) increased as expected. However, it decreased after initiation of cardiopulmonary bypass, despite additional heparin infusion and heparin concentration maintenance. A correlation between platelet factor 4 and heparin resistance was suggested. On discharge, she had no complications. We should consider the possibility of heparin resistance in essential thrombocythemia even when platelet count is adequately controlled.

ABSTRACT

We present a successful case of the management of a 46-year-old woman with an abnormal aortic valve formed by four cusps (three equal large cusps and one smaller cusp; type B according to the Hurwitz and Roberts classification) with a marked loss of coaptation that caused a severe aortic insufficiency (AI). The patient underwent an aortic valvuloplasty of the defect using the glutaraldehyde (GA)-pretreated autologous pericardium, restoring the subnormal function and competency of the aortic valve. The postoperative course was unremarkable. The early follow-up showed a trivial AI and a significant reduction of regurgitant volume was identified in a cardiac magnetic resonance imaging (MRI) when compared to the preoperative state (27.2 vs. 2.1 ml). The follow-up transthoracic echocardiography 1 year after the surgery showed mild AI.

ABSTRACT

BACKGROUND: Current expert consensus recommends remote monitoring for cardiac implantable electronic devices, with at least annual in-office follow-up. We studied safety and resource consumption of exclusive remote follow-up (RFU) in pacemaker patients for 2 years. METHODS: In Japan, consecutive pacemaker patients committed to remote monitoring were randomized to either RFU or conventional in-office follow-up (conventional follow-up) at twice yearly intervals. RFU patients were only seen if indicated by remote monitoring. All returned to hospital after 2 years. The primary end point was a composite of death, stroke, or cardiovascular events requiring surgery, and the primary hypothesis was noninferiority with 5% margin. RESULTS: Of 1274 randomized patients (50.4% female, age 77±10 years), 558 (RFU) and 550 (Conventional follow-up) patients reached either the primary end point or 24 months follow-up. The primary end point occurred in 10.9% and 11.8%, respectively (P=0.0012 for noninferiority). The median (interquartile range) number of in-office follow-ups was 0.50 (0.50-0.63) in RFU and 2.01 (1.93-2.05) in conventional follow-up per patient-year (P<0.001). Insurance claims for follow-ups and directly related diagnostic procedures were 18 800 Yen (16 500-20 700 Yen) in RFU and 21 400 Yen (16 700-25 900 Yen) in conventional follow-up (P<0.001). Only 1.4% of remote follow-ups triggered an unscheduled in-office follow-up, and only 1.5% of scheduled in-office follow-ups were considered actionable. CONCLUSIONS: Replacing periodic in-office follow-ups with remote follow-ups for 2 years in pacemaker patients committed to remote monitoring does not increase the occurrence of major cardiovascular events and reduces resource consumption.

ABSTRACT

The medical uses of three-dimensional (3D) printing are evolving at a rapid pace. The current roles and the future outlooks of this technology for physician-modified endovascular graft (PMEG) in patients with juxtarenal aneurysm are discussed. Fenestrations of PMEG are designed taking into account the geometry of the stent graft. Designing of such stent grafts is extremely complicated, especially when PMEG is planned for the angulated portion of the aorta. A 3D model enables the designing of branch fenestrations, with consideration for the geometrical adaptation of the stent graft in a complex aortic anatomy. With the aid of 3D-printing technology, patients with juxtarenal aortic pathologies can be treated using fenestrated stent grafts, preserving the vital organ circulation and securing a robust length of proximal sealing zone.

ABSTRACT

The GORE EXCLUDER Iliac Branch Endoprosthesis (IBE; W. L. Gore and Associates, Flagstaff, AZ, USA) applicability is limited by the aorto-iliac length (AOL). The shortage may be a major exclusion criterion. An 85-year-old male presented with an abdominal aortic and left common iliac arterial aneurysm. The left-side AOL was 146-mm, which was deemed 19-mm too short for IBE usage. To increase implantation length, the contra-lateral connection stent graft was deployed along the implantation line, wound half-circumferentially around the ipsilateral limb. Any form of endoleak, limb occlusion, and device migration has not been observed for twelve months.

ABSTRACT

A 48-year-old man underwent aortic root remodeling for a giant aneurysm of sinus of Valsalva, 98 mm in diameter, as well as a bicuspid aortic valve. The aortic valve was defined as type 0(L-R) according to Sievers classification and the aortic annulus was highly dilated up to 35 mm. Geometric height of the left and right cusps were 22 mm and 32 mm in diameter, respectively. Dacron straight graft of 24 mm was chosen and each tongue was then created in a 180°fashion. After completion of root reconstruction, external circular suture annuloplasty using CV-0 expanded polytetrafluoroethylene (ePTFE) was made to adjust the annulus down to 22 mm in diameter. The free margin of both cusps were centrally plicated to raise the effective height to 9 mm. Postoperative echocardiography at 2 year showed trivial aortic regurgitation but no root re-dilatation. Remodeling with external circular suture annuloplasty is a reproducible and reliable method to stabilize the root, even for the patient with a giant aneurysm of sinus of Valsalva.

ABSTRACT

AIMS: Tricuspid regurgitation (TR) has been reported to be associated with worse survival in various heart diseases, but there are few data in aortic stenosis (AS). METHODS AND RESULTS: In the Contemporary Outcomes after Surgery and Medical Treatment in Patients with Severe Aortic Stenosis (CURRENT AS) Registry enrolling 3815 consecutive patients with severe AS, there were 628 patients with moderate or severe TR (TR group) and 3187 patients with no or mild TR (no TR group). The study patients were subdivided into the initial aortic valve replacement (AVR) stratum (n = 1197) and the conservative stratum (n = 2618) according to treatment strategy. The primary outcome measure was a composite of aortic valve-related death or hospitalization due to heart failure. The 5-year freedom rate from the primary outcome measure was significantly lower in the TR group than in the no TR group (49.1% vs. 67.3%, P < 0.001). Even after adjusting for confounders, the excess risk of TR relative to no TR for the primary outcome measure remained significant [hazard ratio (HR): 1.25, 95% confidence interval (CI): 1.06-1.48; P = 0.008]. The trend for the excess adjusted risk in the TR group was consistent in the initial AVR and the conservative strata (HR 1.55, 95% CI: 0.97-2.48; P = 0.07; HR 1.22, 95% CI: 1.02-1.46; P = 0.03, respectively). In the initial AVR stratum, the 5-year freedom rate from the primary outcome measure was not different between the two groups with (n = 56) or without (n = 91) concomitant tricuspid annuloplasty (61.5% vs. 72.1%, P = 0.48). CONCLUSION: The presence of clinically significant TR concomitant with severe AS is associated with a poor long-term outcome, regardless of the initial treatment strategy.

ABSTRACT

BACKGROUND: There is no large-scale study comparing postoperative mortality after aortic valve replacement (AVR) for asymptomatic severe aortic stenosis (AS) between initial treatment with AVR vs. eventual AVR after conservative management. Methods and Results: We analyzed data from a multicenter registry enrolling 3,815 consecutive patients with severe AS. Of 1,808 asymptomatic patients, 286 patients initially underwent AVR (initial AVR group), and 377 patients were initially managed conservatively and eventually underwent AVR (AVR after watchful waiting group). Mortality after AVR was compared between the 2 groups. Subgroup analysis according to peak aortic jet velocity (Vmax) at diagnosis was also conducted. There was no significant difference between the 2 groups in 5-year overall survival (OS; 86.0% vs. 84.1%, P=0.34) or cardiovascular death-free survival (DFS; 91.3% vs. 91.1%, P=0.61), but on subgroup analysis of patients with Vmax ≥4.5 m/s at diagnosis, the initial AVR group was superior to the AVR after watchful waiting group in both 5-year OS (88.4% vs. 70.6%, P=0.003) and cardiovascular DFS (91.9% vs. 81.7%, P=0.023). CONCLUSIONS: Asymptomatic severe AS patients who underwent AVR after watchful waiting had a postoperative survival rate similar to those who initially underwent AVR. In a subgroup of patients with Vmax ≥4.5 m/s at diagnosis, however, the AVR after watchful waiting group had worse postoperative survival rate than the initial AVR group.

ABSTRACT

BACKGROUND: There is discordance regarding the effect of symptom status before aortic valve replacement (AVR) on long-term outcome after AVR in severe aortic stenosis (AS).Methods and Results:The CURRENT AS registry is a multicenter retrospective registry enrolling 3,815 consecutive patients with severe AS. Among 1,196 patients managed with the initial AVR strategy, long-term clinical outcomes were compared between the symptomatic patients (n=905), and asymptomatic patients (n=291). Median follow-up interval was 1337 days with a 91% follow-up rate at 2 years. AVR was performed in 886 patients (98%) in the symptomatic group and in 287 patients (99%) in the asymptomatic group. Symptomatic patients were older and more often had comorbidities than asymptomatic patients with similar echocardiographic AS severity. The cumulative 5-year incidences of all-cause death and heart failure (HF) hospitalization were significantly higher in symptomatic patients than in asymptomatic patients (25.6% vs. 15.4%, P=0.001, and 14.2% vs. 3.8%, P<0.001, respectively). On landmark analysis at 30 days after AVR, the differences in mortality and HF hospitalization between the 2 groups were mainly observed beyond 30 days. CONCLUSIONS: When managed with the initial AVR strategy, the long-term outcomes of symptomatic severe AS were worse than those of asymptomatic severe AS. Early AVR strategy might be recommended in some selected asymptomatic severe AS patients with reasonable operative risk.
