Predictors and Prognostic Impact of Nutritional Changes After Transcatheter Aortic Valve Replacement. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2020; 23:68-76. [PMID: 32900641 DOI: 10.1016/j.carrev.2020.08.031] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2020] [Revised: 07/08/2020] [Accepted: 08/17/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Little is known about changes in nutritional status as an index of frailty on clinical outcomes after transcatheter aortic valve replacement (TAVR). This study aimed to assess the clinical impact of serum albumin changes after TAVR. METHODS Changes in serum albumin levels from baseline to 1 year after TAVR were evaluated in 1524 patients who were classified as having hypoalbuminemia (<3.5 g/dl) and normoalbuminemia (≥3.5 g/dl) at each timepoint. The patients were categorized into 4 groups: NN (baseline normoalbuminemia, 1-year normoalbuminemia: n = 1119), HN (baseline hypoalbuminemia, 1-year normoalbuminemia: n = 202), NH (baseline normoalbuminemia, 1-year hypoalbuminemia: n = 121), and HH (baseline hypoalbuminemia, 1-year hypoalbuminemia: n = 82). We also defined late hypoalbuminemia as hypoalbuminemia identified at the 1-year assessment. Clinical outcomes were compared among 4 groups. Multivariable analysis was driven to assess the variables associated with late hypoalbuminemia and long-term mortality. RESULTS The cumulative 3-year mortality was significantly different among the 4 groups (NN: 11.4%, HN: 10.7%, NH: 25.4%, HH: 44.4%, p < 0.001). Multivariable Cox regression analysis revealed that the NH group had a higher mortality risk (hazard ratio [HR]; 2.80 and 3.53, 95% confidence interval [CI]; 1.71-4.57 and 2.06-6.06, p < 0.001 and p < 0.001, respectively), whereas the HN group had a similar risk (HR; 1.16, 95% CI; 0.66-2.06, p = 0.61) compared with the NN group. Baseline hypoalbuminemia, low body mass index, liver disease, peripheral artery disease, and hospital readmission within 1 year were predictors of late hypoalbuminemia (all p < 0.05). CONCLUSION Serial albumin assessment may identify poor prognostic subsets in patients with persistent and late acquired malnutrition after TAVR.

Midterm outcomes after the rescue THV-in-THV procedure: Insights from the multicenter prospective OCEAN-TAVI registry. Catheter Cardiovasc Interv 2020; 97:701-711.

Abstract
OBJECTIVES To confirm whether the rescue transcatheter heart valve in the transcatheter heart valve (THV-in-THV) procedure is effective and feasible, we aimed to assess the midterm outcomes following rescue THV-in-THV procedures. The trends in the usage of the rescue THV-in-THV procedure at the time of transcatheter aortic valve implantation (TAVI) have also been explored. BACKGROUND Midterm outcomes of the rescue THV-in-THV procedure have been poorly defined, though it is popular as an effective method to bail-out some complications in TAVI. METHODS We reviewed data from the Optimized transCathEter vAlvular iNtervention-Transcatheter Aortic Valve Implantation (OCEAN-TAVI) registry and compared the outcomes of TAVI with rescue THV-in-THV and TAVI without rescue THV-in-THV. We also examined the annual rates of rescue THV-in-THV procedures in all the TAVI procedures between 2013 and 2017. RESULTS Among 2,588 patients who underwent TAVI, 26 patients have required rescue THV-in-THV for valve malposition (n = 23) or severe transvalvular regurgitation because of stuck THV leaflets (n = 3). Three cases needed an open conversion, and two died in the hospital. The rates of new permanent pacemaker implantation, acute kidney injury, and stroke were higher in the THV-in-THV group. A two-year cumulative survival and echocardiographic outcomes succeeding rescue THV-in-THV procedure were comparable to non-THV-in-THV cases. The rate of rescue THV-in-THV procedure lessened from 2.6% in 2013 to 0.6% in 2017. CONCLUSIONS The rescue THV-in-THV procedure is an effective and feasible option for THV malpositioning and stuck valve. It has given a comparable survival and a stable valve function over midterm observation periods.

Abstract
Objectives Estimating 1‐year life expectancy is an essential factor when evaluating appropriate indicators for transcatheter aortic valve replacement (TAVR). Background It is clinically useful in developing a reliable risk model for predicting 1‐year mortality after TAVR. Methods We evaluated 2,588 patients who underwent TAVR using data from the Optimized CathEter vAlvular iNtervention (OCEAN) Japanese multicenter registry from October 2013 to May 2017. The 1‐year clinical follow‐up was achieved by 99.5% of the entire population (n = 2,575). Patients were randomly divided into two cohorts: the derivation cohort (n = 1,931, 75% of the study population) and the validation cohort (n = 644). Considerable clinical variables including individual patient's comorbidities and frailty markers were used for predicting 1‐year mortality following TAVR. Results In the derivation cohort, a multivariate logistic regression analysis demonstrated that sex, body mass index, Clinical Frailty Scale, atrial fibrillation, peripheral artery disease, prior cardiac surgery, serum albumin, renal function as estimated glomerular filtration rate, and presence of pulmonary disease were independent predictors of 1‐year mortality after TAVR. Using these variables, a risk prediction model was constructed to estimate the 1‐year risk of mortality after TAVR. In the validation cohort, the risk prediction model revealed high discrimination ability and acceptable calibration with area under the curve of 0.763 (95% confidence interval, 0.728–0.795, p < .001) in the receiver operating characteristics curve analysis and a Hosmer–Lemeshow χ2 statistic of 5.96 (p = .65). Conclusions This risk prediction model for 1‐year mortality may be a reliable tool for risk stratification and identification of adequate candidates in patients undergoing TAVR.

Abstract
AIMS We aimed to evaluate whether optical coherence tomography (OCT)-guided rotational atherectomy (RA) improves stent expansion and clinical outcomes compared to intravascular ultrasound (IVUS)-guided RA. METHODS AND RESULTS From our database, we identified 247 de novo calcified coronary lesions that underwent RA between September 2013 and December 2017. Of these, lesions with no intravascular imaging data (n=11), poor image quality (n=7), balloon angioplasty alone (n=16), and complications (two burr entrapments, two perforations) were excluded. Finally, 88 and 121 lesions that underwent OCT-guided and IVUS-guided RA, respectively, were included in the study. The primary endpoint of the present study was percent stent expansion. Burr upsizing was more frequently performed (55% vs 32%, p=0.001) and the final burr size was significantly larger (1.75 [1.50-1.75] vs 1.50 [1.50-1.75] mm, p<0.001) in the OCT-guided RA group. Percent stent expansion was significantly larger in the OCT-guided RA group (83±15% vs 72±16%, p=0.0004). Although TLR at one year was lower in the OCT-guided RA group, there was no statistical difference (6.8% vs 11.6%, p=0.25). CONCLUSIONS OCT-guided RA for calcified coronary lesions resulted in larger percent stent expansion compared to IVUS-guided RA. OCT-guided RA may be ideal for treating calcified coronary lesions.

Abstract
A 68-year-old man was scheduled to undergo percutaneous coronary intervention for in-stent total occlusion of the severely tortuous right coronary artery. Intravascular ultrasound revealed heavy in-stent calcification. Lesion atherectomy was required; however, severe proximal vessel tortuosity was detected. We introduced a 7-Fr guide-extension catheter beyond the severely tortuous part and performed rotational atherectomy with a 1.5 mm burr. However, the balloon could not expand; therefore, we changed to an orbital atherectomy system. Subsequently, the balloon successfully expanded, and intravascular ultrasound revealed an enlarged lumen. Severe proximal vessel tortuosity limits the use of atherectomy devices; however, a guide-extension catheter delivers the atherectomy device beyond the tortuosity. The delivery of the orbital atherectomy system inside the guide-extension catheter is easy due to its low profile; the debulking effect increases with the number of passes and rotational speed. This strategy is a useful option for treating severe calcified lesions with proximal vessel tortuosity.

Abstract
BACKGROUND The influence of improved mitral regurgitation (MR) on the outcomes of transcatheter aortic valve replacement (TAVR) is unknown. Our aim was to determine the impact of significant preprocedural MR and the improvement of MR after TAVR. METHODS A population of 1587 patients from the Optimized Catheter Valvular Intervention Transcatheter Aortic Valve Implantation (OCEAN-TAVI) registry were evaluated. Preprocedural MR was mild or less in 1443 patients (90.9%) and moderate or severe in 144 patients (9.1%). RESULTS Moderate or severe MR was associated with increased risk for all-cause mortality at 1 year (adjusted hazard ratio, 1.85; 95% confidence interval [CI], 1.20-2.84; P = 0.005) and 2 years (adjusted hazard ratio, 1.64; 95% CI, 1.15-2.34; P = 0.007). At 6 months after TAVR, the MR grade improved in 77.4% of the patients with moderate or severe baseline MR. Multivariate analysis showed that the absence of previous myocardial infarction (odds ratio, 8.00; 95% CI, 1.74-36.8; P = 0.008) and beta-blocker use at baseline (odds ratio, 2.71; 95% CI, 1.09-6.70; P = 0.031) were independently associated with improved MR at 6 months (vs unchanged, worsened MR, or death). Patients with improved MR had a significantly lower rate of midterm readmission for heart failure (11.6%) than those with unchanged or worsened MR (30.8%, P = 0.007). CONCLUSIONS Moderate or severe MR was associated with increased risk of all-cause mortality 2 years after TAVR. Moderate or severe baseline MR was improved in most patients at 6 months after TAVR. Patients with unchanged or worsened MR had an increased rate of readmission for heart failure.

Abstract
OBJECTIVES The purpose of this study was to investigate 30-day and 2-year clinical outcomes, and predictors of 2-year mortality in nonagenarians undergoing transcatheter aortic valve implantation (TAVI). BACKGROUND TAVI has been applied to nonagenarians. However, sufficient clinical data in nonagenarians who could benefit from TAVI are limited. METHODS We evaluated the data from the optimized catheter valvular intervention-TAVI registry. Clinical outcomes were compared between patients' age ≥90 years and age <90 years. Predictive factors of 2-year mortality were assessed by multivariable Cox regression analyses. RESULTS From October 2013 to May 2017, a total of 375 nonagenarians (age ≥90 years) and 2,213 younger patients (age <90 years) were included. Although nonagenarians had a higher surgical risk score, 30-day clinical outcomes were similar between two groups. There were no significant differences in 2-year mortality (22.0% vs. 17.3%; p = .11) and stroke (5.5% vs. 3.9%; p = .31); however, 2-year heart failure readmission was higher in nonagenarians (13.3% vs. 9.0%; p = .03). After adjusting covariates, age ≥90 years was not independent predictor for 2-year outcomes. In nonagenarians, female sex (hazard ratio [HR] = 0.43; 95% confidence interval [CI] = 0.26-0.74; p = .002), chronic kidney disease grade ≥4 (HR = 2.14; 95% CI = 1.21-3.64; p = .01), and Clinical Frailty Scale ≥4 (HR = 1.82; 95% CI = 1.02-3.42; p = .04) were independently associated with 2-year mortality. CONCLUSIONS Clinical outcomes of TAVI in selected nonagenarians were favorable. Severe renal dysfunction and frailty may be important factors to predict mid-term mortality after TAVI in nonagenarians.

Abstract
A 63 year-old woman with claudication underwent endovascular therapy for diffuse stenosis of the right superficial femoral artery in our hospital. We performed paclitaxel-coated balloon angioplasty using the IN.PACT™ Admiral™ and achieved acceptable results. After 42 days, we performed follow-up optical frequency domain imaging for the right superficial femoral artery lesion treated with paclitaxel-coated balloon and observed several high-intensity regions with attenuation on the lumen surface. Sustained drug availability is a notable characteristic of paclitaxel-coated balloon. To the best of our knowledge, this is the first report on the visualization of sustained drug retention on the lumen surface using follow-up optical frequency domain imaging after paclitaxel-coated balloon angioplasty in a human patient with superficial femoral artery disease.

Abstract
OBJECTIVE This retrospective study assessed the safety and efficacy of the ARAHKEY (ARterial sealing with Additional Hemostatic device Kissing with Extravascular and suture-based device deeplY) technique during transcatheter aortic valve replacement (TAVR). BACKGROUND Access site complications are still a major issue to be solved during TAVR using a large caliber sheath. METHODS From February 2014 to June 2019, a total of 302 patients underwent TAVR in our hospital. Twenty-five patients (10.2% of patients who underwent percutaneous transfemoral TAVR [n = 246]) were treated using the ARAHKEY technique, which is the additional use of Exoseal for the common femoral artery puncture site when hemostasis was not achieved with ProGlide alone. RESULTS Complete hemostasis was achieved in all patients (100%). The mean procedural time for hemostasis was 9.8 ± 4.5 min. No complications, including recurrent bleeding, infection, and late acquired hematoma, were observed in this study cohort. CONCLUSION The ARAHKEY technique is a safe method and should be considered as a secondary option when hemostasis is not achieved with ProGlide during TAVR.

Abstract
AIMS The newly formed geometry between the native Valsalva and implanted transcatheter heart valve (THV) may induce local thrombogenicity. This study aimed to assess the incidence of and the clinical outcomes associated with Valsalva thrombus formation after transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS We retrospectively evaluated the multidetector computed tomography (MDCT) data of 338 patients following transcatheter aortic valve implantation (TAVI) using a balloon-expandable THV. The Valsalva and leaflet thrombi were assessed by MDCT at the left coronary cusp (LCC), right coronary cusp (RCC), and non-coronary cusp (NCC). Combined endpoints such as death, stroke, and readmission for heart failure rates in patients with and without Valsalva and/or leaflet thrombus were examined at two years. The overall incidence of Valsalva and leaflet thrombi was 8.9% and 8.3%, respectively. Significant differences in the location of the Valsalva thrombus in the LCC, RCC, and NCC were noted (5.0%, 4.2%, 8.9%, respectively, p<0.001). The independent predictor for increased risk of Valsalva thrombus was high Valsalva area to implanted THV size ratio (odds ratio 11.8, 95% confidence interval [CI]: 1.67-83.0, p=0.013). Combined endpoints were similar in patients with and without Valsalva thrombus, Valsalva/leaflet thrombus, and leaflet thrombus (p>0.05 for all). CONCLUSIONS Valsalva thrombus was detected in 8.9% of patients following balloon-expandable THV implantation and was common in the LCC, but it did not increase the risk of adverse events after TAVI.

Abstract
Background Although transcatheter aortic valve replacement (TAVR) is the least invasive treatment for patients with symptomatic aortic stenosis, some patients hesitate to undergo the procedure. We investigated the clinical impact of treatment delay after patient refusal of TAVR. Methods and Results We used the Japanese OCEAN (Optimized Catheter valvular intervention) regsitry data of 1542 patients who underwent TAVR. Refusal was defined as at least 1 refusal of TAVR at the time of informed consent. Patients were separated into 2 groups: refusal (28/1542, 1.8%) and non‐refusal (1514/1542, 98.2%). We compared the baseline characteristics, procedural outcomes, and mortality rates between the groups. Additionally, data on reasons for refusal and those leading to eventually undergoing TAVR were collected. Age, surgical risk scores, and frailty were higher in the refusal group than in the non‐refusal group (P<0.05 for all). Periprocedural complications did not differ between groups, whereas 30‐day and cumulative 1‐year mortality were significantly higher in the refusal group than in the non‐refusal group (7.1% versus 1.3%, P=0.008 and 28.8% versus 10.3%, P=0.010, respectively). Multivariate Cox regression analysis revealed that TAVR refusal was an independent predictor of increased midterm mortality (hazard ratio: 3.37; 95% confidence interval: 1.52–7.48; P=0.003). The most common reason for refusal was fear (13/28, 46.4%), and the most common reason for changing their mind was worsening heart failure (21/28, 75.0%). All patients in the refusal group decided to undergo TAVR within 20 months (median: 5.5 months). Conclusions Refusing TAVR even once led to poorer prognosis; therefore, this fact should be clearly discussed when obtaining informed consent.

Abstract
Abstract
Background
Silent cerebral thromboembolism (CE) in catheter ablation for atrial fibrillation (AF) is not rare. Prior our study has reported lower incidence of silent CE in AF radiofrequency (RF) ablation using irrigated-tip catheter than conventional 4 or 8mm-tip catheter. In addition, the incidence of silent CE in AF ablation under direct oral anticoagulant (DOAC) was equivalent to continuous therapeutic warfarin. Recently pulmonary vein isolation (PVI) using cryoballoon (CB) has emerged as an alternative technique to RF ablation because some studies suggested that the efficacy for PVI by CB was equivalent to RF. However, incidence of silent CE in CB ablation under the use of DOAC is unknown.
Objective
We aimed to evaluate the incidence new silent CE in AF ablation using CB system compared with irrigated RF system under the use of DOAC.
Methods
322 consecutive patients with paroxysmal or persistent AF (155 using CB system, 167 using RF system) who underwent the first AF ablation were taking DOAC more than one month prior to the procedure. Throughout AF ablation procedure, heparin was administered to maintain activated clotting time (ACT) between 300 and 400 seconds. Head MRI was performed in all patients within 24 hours after the procedure.
Results
In 14 (9.0%) patients using CB and in 20 (12.0%) patients using RF, head MRI showed new embolic lesions without neurological symptom (P=0.469). Although the amount of heparin during the procedure in group CB was significantly less than in group RF (16134±3125 U vs. 18689±5222 U; P<0.0001), amount of heparin per hour in group CB was more than in group RF (8335±1955 U/h vs. 6143±1918 U/h; P<0.0001) because procedure time in group CB was shorter than in group RF (121.3±34.1 min vs. 189.5±47.4 min; P<0.0001). Mean ACT in both groups was maintained high level (3367±25.3 sec. vs. 338.6±23.5 sec.; P=0.479). In univariate analysis, minimum ACT during procedure, as before puncture of interatrial septum, were significantly correlated with the incidence of silent CE (P=0.027).
Conclusions
The incidence of silent CE in AF ablation using CB system was lower than RF system, although it was not a significant difference between different ablation techniques for AF. In AF ablation, the use of CB may be preferred rather than RF as ablation system in regard to risk reduction of thromboembolic complications.

Abstract
Abstract
Background
Dual-antiplatelet therapy (DAPT) after second-generation drug eluting stent (2-DES) implantation reduced the risk of stent thrombosis and subsequent ischemic events, with an increase in bleeding risk. Although chronic kidney disease patients have high ischemic and bleeding risk, little is known about both risks in hemodialysis patients after 2-DES implantation during DAPT.
Method
From July 2009 to March 2017, we retrospectively analyzed post-discharge major adverse cardiac and cerebrovascular events [MACCE: cardiac death, myocardial infarction, target vessel revascularization (TVR) and cerebral infarction] and bleeding events in 644 consecutive patients during DAPT after 2-DES implantation. We divided them into 2 groups [102 hemodialysis (HD) and 518 non-hemodialysis (Non-HD) patients, mean age, 71±10 years] after excluding 24 patients (lost to follow up and peritoneal dialysis). Follow-up period was 49±24 months. Median DAPT duration was 12 months. The primary endpoint was MACCE. The secondary endpoint was bleeding events according to the Bleeding Academic Research Consortium (BARC) type 2, 3, or 5. MACCE and bleeding events were compared between HD and Non-HD by using the propensity score-matching (PSM) method.
Results
Among the 620 eligible patients, the primary and secondary events occurred in 207 (33.3%) and 76 (12.3%) patients, respectively. The rates of unadjusted MACCE [HD vs Non-HD: 53.9% vs 29.3%; Hazard ratio (HR) 2.39, p<0.01] and bleeding events (HD vs Non-HD: 21.6% vs 10.4%; HR 2.50, p<0.01) were significantly higher in HD than Non-HD.
After 1-to-1 propensity score adjustment for baseline differences (hypertension, diabetes mellitus, low ejection fraction, low albumin, anemia, and high C-reactive protein), a total of 160 patients (80 HD vs 80 Non-HD) was created. The rate of MACCE [HD vs Non-HD: 52.5% vs 31.3%; adjusted HR 2.04, p<0.01] was significantly higher in HD than Non-HD. Regarding MACCE, cardiac death (HD vs Non-HD: 18.8% vs 8.8%; adjusted HR 2.65, p=0.03) and TVR (HD vs Non-HD: 15.0% vs 6.3%; adjusted HR 2.74, p=0.046) occurred significantly higher in HD. On the other hand, bleeding events did not exhibit significant differences though HD had a numerically higher event rate (HD vs Non-HD: 25.0% vs 16.3%; adjusted HR 1.68, p=0.15), indicating that the bleeding risk in HD would be strongly dependent on the patient's background.
Conclusions
As a result of PSM, HD was shown to contribute to ischemic risk rather than bleeding risk. Even in the 2-DES era, HD was an independent risk factor of cardiac death and TVR. Therefore, further study on the current regimen of DAPT would be necessary while balancing both ischemic and bleeding risk.
