RESUMO

Background Clinical characteristics and outcomes of takotsubo syndrome (TTS) patients with malignancy have not been fully elucidated. This study sought to explore differences in clinical characteristics and to investigate short- and long-term outcomes in TTS patients with or without malignancy. Methods and Results TTS patients were enrolled from the International Takotsubo Registry. The TTS cohort was divided into patients with and without malignancy to investigate differences in clinical characteristics and to assess short- and long-term mortality. A subanalysis was performed comparing long-term mortality between a subset of TTS patients with or without malignancy and acute coronary syndrome (ACS) patients with or without malignancy. Malignancy was observed in 16.6% of 1604 TTS patients. Patients with malignancy were older and more likely to have physical triggers, but less likely to have emotional triggers compared with those without malignancy. Long-term mortality was higher in patients with malignancy (P<0.001), while short-term outcome was comparable (P=0.17). In a subanalysis, long-term mortality was comparable between TTS patients with malignancies and ACS patients with malignancies (P=0.13). Malignancy emerged as an independent predictor of long-term mortality. Conclusions A substantial number of TTS patients show an association with malignancy. History of malignancy might increase the risk for TTS, and therefore, appropriate screening for malignancy should be considered in these patients.

RESUMO

AIMS: Peri-procedural transcatheter valve embolization and migration (TVEM) is a rare but potentially devastating complication of transcatheter aortic valve implantation (TAVI). We sought to assess the incidence, causes, and outcome of TVEM in a large multicentre cohort. METHODS AND RESULTS: We recorded cases of peri-procedural TVEM in patients undergoing TAVI between January 2010 and December 2017 from 26 international sites. Peri-procedural TVEM occurred in 273/29 636 (0.92%) TAVI cases (age 80.8 ± 7.3 years; 53.8% female), of which 217 were to the ascending aorta and 56 to the left ventricle. The use of self-expanding or first-generation prostheses and presence of a bicuspid aortic valve were independent predictors of TVEM. Bail-out measures included repositioning attempts using snares or miscellaneous tools (41.0%), multiple valve implantations (83.2%), and conversion to surgery (19.0%). Using 1:4-propensity matching, we identified a cohort of 235 patients with TVEM (TVEMPS) and 932 patients without TVEM (non-TVEMPS). In the matched cohort, all-cause mortality was higher in TVEMPS than in non-TVEMPS at 30 days (18.6% vs. 4.9%; P < 0.001) and after 1 year (30.5% vs. 16.6%; P < 0.001). Major stroke was more frequent in TVEMPS at 30 days (10.6% vs. 2.8%; P < 0.001), but not at 1 year (4.6% vs. 1.9%; P = 0.17). The need for emergent cardiopulmonary support, major stroke at 30 days, and acute kidney injury Stages 2 and 3 increased the risk of 1-year mortality, whereas a better renal function at baseline was protective. CONCLUSION: Transcatheter valve embolization and migration occurred in approximately 1% and was associated with increased morbidity and mortality.

RESUMO

AIMS: We aimed to evaluate the frequency, clinical features, and prognostic implications of cardiac arrest (CA) in takotsubo syndrome (TTS). METHODS AND RESULTS: We reviewed the records of patients with CA and known heart rhythm from the International Takotsubo Registry. The main outcomes were 60-day and 5-year mortality. In addition, predictors of mortality and predictors of CA during the acute TTS phase were assessed. Of 2098 patients, 103 patients with CA and known heart rhythm during CA were included. Compared with patients without CA, CA patients were more likely to be younger, male, and have apical TTS, atrial fibrillation (AF), neurologic comorbidities, physical triggers, and longer corrected QT-interval and lower left ventricular ejection fraction on admission. In all, 57.1% of patients with CA at admission had ventricular fibrillation/tachycardia, while 73.7% of patients with CA in the acute phase had asystole/pulseless electrical activity. Patients with CA showed higher 60-day (40.3% vs. 4.0%, P < 0.001) and 5-year mortality (68.9% vs. 16.7%, P < 0.001) than patients without CA. T-wave inversion and intracranial haemorrhage were independently associated with higher 60-day mortality after CA, whereas female gender was associated with lower 60-day mortality. In the acute phase, CA occurred less frequently in females and more frequently in patients with AF, ST-segment elevation, and higher C-reactive protein on admission. CONCLUSIONS: Cardiac arrest is relatively frequent in TTS and is associated with higher short- and long-term mortality. Clinical and electrocardiographic parameters independently predicted mortality after CA.

RESUMO

Introducción y objetivos: La incidencia de implante de marcapasos permanente (IMP) y nuevas alteraciones de la conducción (AC) con la ACURATE neo (Symetis S.A., Eclubens, Suiza) no se ha estudiado en detalle. Nuestro objetivo fue analizar sus predictores, evaluándose los factores relacionados con el paciente y con el dispositivo, tal como la profundidad del implante y la relación entre el dispositivo y el anillo (RDA). Métodos: De una población multicéntrica, se realizaron 2 análisis: nuevos IMP (n = 283), e IMP/nuevas AC en pacientes sin AC previas o marcapasos (n = 232). Resultados: En el 9,9% de los pacientes se necesitó nuevo IMP, que se asoció con un mayor índice de masa corporal, mayor proporción de bloqueo de rama derecha y bradicardia. Ni el implante de la prótesis ni la RDA difirieron entre pacientes con o sin IMP. En el análisis multivariante ni la RDA (OR = 1,010; IC95%, 0,967-1,055; p = 0,7), ni la profundidad del implante (OR = 0,972; IC95%, 0,743-1,272; p = 0,8) fueron predictores de IMP. Solo el índice de masa corporal, la bradicardia y el bloqueo de rama derecha persistieron como predictores independientes. El IMP/nueva aparición de AC ocurrió en el 22,8% de los pacientes y se asoció con un mayor EuroSCORE logístico. Ni la profundidad del implante ni la RDA eran diferentes en pacientes con o sin IMP/nueva aparición de AC (7,3 ± 1,9 frente a 7,1 ± 1,5 mm; p = 0,6 y 41,0 ± 7,9 frente a 42,2 ± 10,1%; p = 0,4). El único predictor de IMP/nuevo inicio de AC fue un mayor EuroSCORE logístico (OR = 1,039; IC95%, 1,008-1,071; p = 0,013). Conclusiones: La proporción de nuevos IMP y nueva aparición de AC eran inferiores con la ACURATE neo. Estos hechos están principalmente influenciados por las características de los pacientes y no por los factores dependientes del dispositivo


Introduction and objectives: The incidence of permanent pacemaker implantation (PPI) and new conduction abnormalities (CA) with the ACURATE neo (Symetis S.A., Eclubens, Switzerland) has not been studied in detail. We aimed to analyze their predictors, evaluating patient- and device-related factors, including implantation depth and device-to-annulus ratio (DAR). Methods: Two analyses of a multicenter population were performed: new PPI in pacemaker-naive patients (n = 283), and PPI/new-CA in patients without prior CA or pacemaker (n = 232). Results: A new PPI was required in 9.9% of patients, who had a higher body mass index, higher rate of right bundle branch block and bradycardia. Neither implantation depth nor DAR differed in patients with PPI compared with those without. In the multivariable analysis neither DAR (OR, 1.010; 95%CI, 0.967-1.055; P = .7) nor implantation depth (OR, 0.972; 95%CI, 0.743-1.272; P = .8) predicted PPI. Only high body mass index, bradycardia and right bundle branch block persisted as independent predictors. PPI/new-onset CA occurred in 22.8% of patients and was associated with a higher logistic EuroSCORE. Neither implantation depth nor DAR differed in patients with PPI/new-CA vs those without (7.3 ± 1.9 vs 7.1 ± 1.5 mm; P = .6 and 41.0 ± 7.9 vs 42.2 ± 10.1%; P = .4). The only predictor of PPI/new-CA was a higher logistic EuroSCORE (OR, 1.039; 95%CI, [1.008-1.071]; P = .013). Conclusions: New PPI and new-onset CA rates were low with the ACURATE neo. These were mainly influenced by patient characteristics and not by device-depending factors

RESUMO

BACKGROUND: Prognosis of Takotsubo syndrome (TTS) remains controversial due to scarcity of available data. Additionally, the effect of the triggering factors remains elusive. OBJECTIVES: This study compared prognosis between TTS and acute coronary syndrome (ACS) patients and investigated short- and long-term outcomes in TTS based on different triggers. METHODS: Patients with TTS were enrolled from the International Takotsubo Registry. Long-term mortality of patients with TTS was compared to an age- and sex-matched cohort of patients with ACS. In addition, short- and long-term outcomes were compared between different groups according to triggering conditions. RESULTS: Overall, TTS patients had a comparable long-term mortality risk with ACS patients. Of 1,613 TTS patients, an emotional trigger was detected in 485 patients (30%). Of 630 patients (39%) related to physical triggers, 98 patients (6%) had acute neurologic disorders, while in the other 532 patients (33%), physical activities, medical conditions, or procedures were the triggering conditions. The remaining 498 patients (31%) had no identifiable trigger. TTS patients related to physical stress showed higher mortality rates than ACS patients during long-term follow-up, whereas patients related to emotional stress had better outcomes compared with ACS patients. CONCLUSIONS: Overall, TTS patients had long-term outcomes comparable to age- and sex-matched ACS patients. Also, we demonstrated that TTS can either be benign or a life-threating condition depending on the inciting stress factor. We propose a new classification based on triggers, which can serve as a clinical tool to predict short- and long-term outcomes of TTS.

RESUMO

OBJECTIVES: This study sought to compare 2 next-generation transcatheter heart valves (THV), the self-expanding ACURATE neo (NEO) and the balloon-expandable SAPIEN 3 (S3), in terms of device failure and early safety at 30 days. BACKGROUND: Deployment of these THV showed promising initial clinical results. However, no comparative data are available. METHODS: Of 1,121 treated patients at 3 centers, a 1-to-2 nearest neighbor matching was performed to identify 2 patients treated with S3 (n = 622) for each patient treated with NEO (n = 311). RESULTS: In-hospital complications were comparable between NEO and S3, including stroke (1.9% vs. 2.4%; p = 0.64), major vascular complications (10.3% vs. 8.5%; p = 0.38), or life-threatening bleeding (4.2% vs. 3.7%; p = 0.72). Device failure with NEO was comparable with S3 (10.9% vs. 9.6%; odds ratio: 1.09 [95% confidence interval: 0.69 to 1.73]; p = 0.71) with more paravalvular leakage (PVL II+, 4.8% vs. 1.8%; p = 0.01), but less elevated gradients (≥20 mm Hg, 3.2% vs. 6.9%; p = 0.02) and pacemaker implantations (9.9% vs. 15.5%; p = 0.02). Thirty-day mortality (2.3% vs. 1.9%; p = 0.74) and the early safety composite endpoint (15.8% vs. 15.6%; hazard ratio: 0.97 [95% confidence interval: 0.68 to 1.39]; p = 0.88) were similar with NEO and S3. CONCLUSIONS: Very high success rates were achieved for both valves, and the clinical and procedural results were comparable. Compared with S3, NEO was associated with less new pacemaker implantations and less elevated gradients, but with more paravalvular leakage.

RESUMO

Introducción y objetivos: El rendimiento de las puntuaciones de riesgo tradicionales para predecir el riesgo tras el implante percutáneo válvula aórtica (TAVI) no es adecuado. Las altas concentraciones plasmáticas de antígeno carbohidrato 125 (CA125) se han asociado a un aumento del riesgo de eventos adversos tras TAVI. En este trabajo se evalúa el valor pronóstico adicional del CA125 sobre la puntuación EuroSCORE para la predicción de riesgo a largo plazo. Métodos y resultados: Durante una mediana de seguimiento de 59 semanas, murieron 115 de 422 pacientes (27%) después de la TAVI. La mortalidad fue mayor entre aquellos con CA125 elevado (> 30 U/ml) y EuroSCORE ≥ mediana (el 47 frente al 20%; p < 0,001; y el 38 frente al 16%; p < 0,001 respectivamente). En el análisis multivariable, el CA125 (> 30 U/ml) seguía asociado con la mortalidad (hazard ratio [HR] = 2,16; intervalo de confianza del 95% [IC95%], 1,48-3,15; p < 0,001), mejoró la capacidad discriminativa del modelo (estadístico C = 0,736 frente a C = 0,731), el índice neto de reclasificación (51%; IC95%, 33-73) y el índice de mejora de la reclasificación (3,5%; IC95%, 0,5-8,4). La combinación de CA125 y EuroSCORE permitió la creación de una variable de 4 categorias (+, elevado, -, no elevado; C1, CA125- EuroSCORE-; C2, CA125+ EuroSCORE-; C3, CA125- EuroSCORE+, y C4, CA125+ EuroSCORE+). Los pacientes pertenecientes a C1 presentaron la menor mortalidad (14%, 26/181); C2 y C3, intermedia (27% [8/30] y 28% [37/131] respectivamente). Los pertenecientes a C4 presentaron la mayor mortalidad (55% [44/80]; p para la tendencia < 0,001). Conclusiones: El CA125 ofrece información pronóstica adicional a la proporcionada por la puntuación EuroSCORE. La elevación de ambos indicadores se asoció a peor pronóstico (AU)


Introduction and objectives: Conventional risk scores have not been accurate in predicting peri- and postprocedural risk of patients undergoing transcatheter aortic valve implantation (TAVI). Elevated levels of the tumor marker carbohydrate antigen 125 (CA125) have been linked to adverse outcomes after TAVI. We studied the additional value of CA125 to that of the EuroSCORE in predicting long-term mortality after TAVI. Methods and results: During a median follow-up of 59 weeks, 115 of 422 patients (27%) died after TAVI. Mortality was higher with elevated CA125 (> 30 U/mL) and EuroSCORE (> median) (47% vs 20%, P < .001 and 38% vs 16%, P < .001, respectively). In the multivariable analysis, CA125 (> 30 U/mL) remained an independent predictor of mortality (hazard ratio [HR], 2.16; 95% confidence interval [95%CI], 1.48-3.15; P < .001) and improved the predictive capability of the model (C-statistic: 0.736 vs 0.731) and the net reclassification index (51% 95%CI, 33-73) with an integrated discriminative improvement of 3.5% (95%CI, 0.5-8.4). A new variable (CA125-EuroSCORE) was created, with the combinations of the 2 possible binary states of these variables (+, elevated, -, not elevated; C1: CA125- EuroSCORE-; C2: CA125+ EuroSCORE-; C3: CA125- EuroSCORE+; C4: CA125+ EuroSCORE+). Patients in C1 exhibited the lowest cumulative mortality rate (14% [26 of 181]). Mortality was intermediate for C2 (CA125 > 30 U/mL and EuroSCORE ≤ median) and C3 (CA125 ≤ 30 U/mL and EuroSCORE > median): 27% (8 of 30) and 28% (37 of 131), respectively. Patients in C4 (CA125 > 30 U/mL and EuroSCORE > median) exhibited the highest mortality (55% [44 of 80], P-value for trend < .001). Conclusions: CA125 offers additional prognostic information beyond that obtained by the EuroSCORE. Elevation of both markers was associated with a poor prognosis (AU)

RESUMO

A middle-aged female suffering from ARVD presented for routine follow-up 8 weeks after right ventricular radiofrequency ablation of recurring ventricular tachycardia. Echocardiography revealed two right ventricular thrombi in the scar area of right ventricular radiofrequency ablation. Ablation-related thromboembolic events should be considered as possible complication in patients suffering from ARVD.

RESUMO

OBJECTIVES: This study investigates the influence of implantation depth and prosthesis oversizing on conduction abnormalities (CA) and permanent pacemaker implantation (PPI) after SAPIEN 3 (Edwards Lifesciences, Irvine, California) implantation. BACKGROUND: CA and PPIs are frequent complications after transcatheter aortic valve replacement with a next-generation balloon-expandable transcatheter heart valve (SAPIEN 3). The potential underlying mechanisms are incompletely understood. METHODS: Of 244 patients treated with SAPIEN 3,208 without a previous pacemaker and 184 without baseline CA were analyzed. We assessed the association of angiographic implantation depth (% of frame height below the annulus) and degree of oversizing with PPI and CA. RESULTS: New PPI and new or worsened CA or PPI occurred in 16% (34 of 208) and 31% (57 of 184), respectively. Patients requiring PPI had a higher prevalence of atrial fibrillation (44% vs. 24%; p = 0.017), complete right bundle branch block (27% vs. 5%; p = 0.001), and bradycardia (<60 beats/min, 38% vs. 21%; p = 0.034). In patients with new CA or PPI, implantation depth was lower (at septal side: 29 ± 8% vs. 25 ± 7%; p = 0.003), and rate of oversizing was higher (19% [11 of 57] vs. 6% [8 of 126]; p = 0.007). Independent predictors of new or worsened CA or PPI were implantation depth at septal side (odds ratio [OR]: 1.063 [95% confidence interval (CI): 1.017 to 1.110]; p = 0.006 per % of frame below the aortic annulus), oversizing (OR: 3.489 [95% CI: 1.236 to 9.848]; p = 0.018), and QRS duration (OR: 1.033 [95% CI: 1.011 to 1.056]; p = 0.003 per ms). CONCLUSIONS: Implantation depth and prosthesis oversizing were associated with a higher rate of new CA or PPI using the SAPIEN 3. Thus, avoidance of deep implantation and extreme oversizing may reduce these complications.

RESUMO

Introducción y objetivos: El implante percutáneo de válvula aórtica se utiliza de manera creciente en pacientes con estenosis aórtica. Los trastornos de la conducción intraventricular y los implantes de marcapasos permanente tras la intervención siguen siendo motivo de gran preocupación. Recientemente, la válvula protésica Edwards SAPIEN XT ha sido reemplazada por la SAPIEN 3. El objetivo de este estudio es determinar la incidencia de trastornos de la conducción intraventricular de nueva aparición y la necesidad de implantes de marcapasos permanente comparando los dos dispositivos. Métodos: Se analizó a los últimos 103 pacientes consecutivos a los que se realizó implante percutáneo de válvula aórtica SAPIEN XT antes de que se utilizara la válvula SAPIEN 3 y a los 105 pacientes consecutivos a los que se implantó la válvula SAPIEN 3. Con objeto de analizar los implantes de marcapasos permanentes y los trastornos de la conducción intraventricular de nueva aparición, se excluyó del estudio a los pacientes en los que se daban estas características en situación basal. Se registraron electrocardiogramas en situación basal, después de la intervención y antes del alta. Resultados: El uso del dispositivo SAPIEN 3 se asoció a un porcentaje superior de éxitos de implante del dispositivo (el 100 frente al 92%; p = 0,005) y un porcentaje inferior de fuga paravalvular (0 frente al 7%; p < 0,001). La incidencia de implantes de marcapasos permanente fue del 12,6% (23 de 183), sin que se apreciaran diferencias entre los dos grupos (SAPIEN 3, el 12,5% [12 de 96]; SAPIEN XT, el 12,6% [11 de 87]; p = 0,99). El uso del dispositivo SAPIEN 3 se asoció a mayor frecuencia de trastornos de la conducción intraventricular de nueva aparición (el 49 frente al 27%; p = 0,007) como consecuencia de la mayor frecuencia de bloqueos fasciculares (el 17 frente al 5%; p = 0,021). No hubo diferencia estadísticamente significativa por lo que respecta a los bloqueos de rama izquierda transitorios frente a persistentes (el 29% [20 de 69] frente al 19% [12 de 64]; p = 0,168) al comparar el SAPIEN 3 con el SAPIEN XT (el 28% [19 de 69] frente al 17% [11 de 64]; p = 0,154). Conclusiones: Se observó una tendencia a mayor frecuencia de trastornos de la conducción intraventricular de nueva aparición con SAPIEN 3 que con SAPIEN XT, si bien esto no conllevó mayor frecuencia de implante de marcapasos permanentes (AU)


Introduction and objectives: Transcatheter aortic valve implantation is increasingly used in patients with aortic stenosis. Post-procedural intraventricular conduction abnormalities and permanent pacemaker implantations remain a serious concern. Recently, the Edwards SAPIEN 3 prosthesis has replaced the SAPIEN XT. We sought to determine the incidences of new-onset intraventricular conduction abnormalities and permanent pacemaker implantations by comparing the 2 devices. Methods: We analyzed the last consecutive 103 patients undergoing transcatheter aortic valve implantation with SAPIEN XT before SAPIEN 3 was used in the next 105 patients. To analyze permanent pacemaker implantations and new-onset intraventricular conduction abnormalities, patients with these conditions at baseline were excluded. Electrocardiograms were recorded at baseline, after the procedure, and before discharge. Results: SAPIEN 3 was associated with higher device success (100% vs 92%; P = .005) and less paravalvular leakage (0% vs 7%; P < .001). The incidence of permanent pacemaker implantations was 12.6% (23 of 183) with no difference between the 2 groups (SAPIEN 3: 12.5% [12 of 96] vs SAPIEN XT: 12.6% [11 of 87]; P = .99). SAPIEN 3 was associated with a higher rate of new-onset intraventricular conduction abnormalities (49% vs 27%; P = .007) due to a higher rate of fascicular blocks (17% vs 5%; P = .021). There was no statistically significant difference in transient (29% [20 of 69] vs persistent 19% [12 of 64]; P = .168) left bundle branch blocks (28% [19 of 69] vs 17% [11 of 64]; P = .154) when SAPIEN 3 was compared with SAPIEN XT. Conclusions: We found a trend toward a higher rate of new-onset intraventricular conduction abnormalities with SAPIEN 3 compared with SAPIEN XT, although this did not result in a higher permanent pacemaker implantation rate (AU)

RESUMO

BACKGROUND: The natural history, management, and outcome of takotsubo (stress) cardiomyopathy are incompletely understood. METHODS: The International Takotsubo Registry, a consortium of 26 centers in Europe and the United States, was established to investigate clinical features, prognostic predictors, and outcome of takotsubo cardiomyopathy. Patients were compared with age- and sex-matched patients who had an acute coronary syndrome. RESULTS: Of 1750 patients with takotsubo cardiomyopathy, 89.8% were women (mean age, 66.8 years). Emotional triggers were not as common as physical triggers (27.7% vs. 36.0%), and 28.5% of patients had no evident trigger. Among patients with takotsubo cardiomyopathy, as compared with an acute coronary syndrome, rates of neurologic or psychiatric disorders were higher (55.8% vs. 25.7%) and the mean left ventricular ejection fraction was markedly lower (40.7±11.2% vs. 51.5±12.3%) (P<0.001 for both comparisons). Rates of severe in-hospital complications including shock and death were similar in the two groups (P=0.93). Physical triggers, acute neurologic or psychiatric diseases, high troponin levels, and a low ejection fraction on admission were independent predictors for in-hospital complications. During long-term follow-up, the rate of major adverse cardiac and cerebrovascular events was 9.9% per patient-year, and the rate of death was 5.6% per patient-year. CONCLUSIONS: Patients with takotsubo cardiomyopathy had a higher prevalence of neurologic or psychiatric disorders than did those with an acute coronary syndrome. This condition represents an acute heart failure syndrome with substantial morbidity and mortality. (Funded by the Mach-Gaensslen Foundation and others; ClinicalTrials.gov number, NCT01947621.).

RESUMO

HISTORY AND CLINICAL FINDINGS: A 42-year old female patient was admitted in cardiogenic shock with pulmonary edema requiring prehospital intubation and mechanical ventilation. INVESTIGATIONS: | Emergency cardiac catheterization because of suspected acute coronary syndrome excluded coronary artery disease. Ventriculography and echocardiography suggested an inverse Tako-Tsubo cardiomyopathy with akinesia of the basal left ventricular myocardium and only apical preserved wall motion. TREATMENT AND COURSE: Under intensive care therapy with mechanical ventilation, inotropic support, infusion of saline and intraaortal balloon pumping, left ventricular function improved. After discontinuation of mechanical ventilation and discharge from ICU, the patient repeatedly suffered from panic attacks. She was therefore transferred to a psychosomatic center. There she exhibited repeated hypertensive crisis. Ultrasound of the kidney showed an adrenal mass. Together with elevated plasma catecholamines, the diagnosis of pheochromocytoma was suspected. This could be proved by magnetic resonance imaging. After surgical removement of the adrenal mass, the patient was free of symptoms.

RESUMO

OBJECTIVES: Evaluation of 30-day outcomes after transcatheter aortic valve replacement (TAVR) with the novel balloon-expandable SAPIEN 3 (S3) transcatheter heart valve (THV) (Edwards Lifesciences, Irvine, California) emphasizing the updated Valve Academic Research Consortium (VARC-2) criteria. BACKGROUND: Preliminary data on clinical performance with the S3 THV are promising. However, information regarding 30-day outcome is limited. METHODS: A total of 250 consecutive patients undergoing transfemoral TAVR with the S3 THV at our center were enrolled, and outcomes according to VARC-2 criteria were analyzed at 30 days. RESULTS: The mean age was 81.0 ± 6.2 years, median logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) and Society of Thoracic Surgeons score were 12.1% and 4.4%, respectively. VARC-2-defined device success was achieved in 244 patients (97.6%); moderate paravalvular leakage developed in 5 patients (2.0%). One patient (0.4%) died of a noncardiac cause and 8 patients (3.2%) had a stroke. Life-threatening bleeding and major vascular complications occurred in 12 (4.8%) and 9 (3.6%) of the patients, respectively. From discharge to 30 days, 5 patients (2.0%) were hospitalized due to valve-related symptoms or worsening of heart failure. The VARC-2 composite early safety endpoint was observed in 25 patients (10.0%). Permanent pacemaker implantation rate at 30 days was 15.2%. Myocardial infarction, coronary obstruction requiring intervention, valve-related dysfunction, and endocarditis were not observed. CONCLUSIONS: We found very good 30-day results using the novel S3 THV with a low rate of clinical events according to VARC-2 criteria. The S3 THV is associated with high procedural success and favorable early safety profile. The need for pacemaker implantations appears to be more frequent than with its predecessor.

RESUMO

IMPORTANCE: The role of vascular closure devices (VCD) for the achievement of hemostasis in patients undergoing transfemoral coronary angiography remains controversial. OBJECTIVE: To compare outcomes with the use of 2 hemostasis strategies after diagnostic coronary angiography performed via transfemoral access-a VCD-based strategy with 2 types of devices, an intravascular device and an extravascular device, vs standard manual compression. The primary hypothesis to be tested was that femoral hemostasis achieved through VCD is noninferior to manual compression in terms of vascular access-site complications. A secondary objective was the comparison of the 2 types of VCD. DESIGN, SETTING, AND PARTICIPANTS: Randomized, large-scale, multicenter, open-label clinical trial. We enrolled 4524 patients undergoing coronary angiography with a 6 French sheath via the common femoral artery from April 2011 through May 2014 in 4 centers in Germany. Last 30-day follow-up was performed in July 2014. INTERVENTIONS: After angiography of the access site, patients were randomized to hemostasis with an intravascular VCD, extravascular VCD, or manual compression in a 1:1:1 ratio. MAIN OUTCOMES AND MEASURES: Primary end point: the composite of access site-related vascular complications at 30 days after randomization with a 2% noninferiority margin. Secondary end points: time to hemostasis, repeat manual compression, and VCD failure. An α-level of .025 was chosen for primary and secondary comparisons. RESULTS: Of the 4524 enrolled patients, 3015 were randomly assigned to a VCD group (1509 received intravascular VCD and 1506 received extravascular VCD) and 1509 patients were randomly assigned to the manual compression group. Before hospital discharge, duplex sonography of the access site was performed in 4231 (94%) patients. The primary end point was observed in 208 patients (6.9%) assigned to receive a VCD and 119 patients (7.9%) assigned to manual compression (difference, -1.0% [1-sided 97.5% CI, 0.7%]; P for noninferiority<.001). Time to hemostasis was significantly shorter in patients with VCD (1 minute [interquartile range {IQR}, 0.5-2.0]), vs manual compression (10 minutes [IQR, 10-15]; P < .001). Time to hemostasis was significantly shorter among patients with intravascular VCD (0.5 minute [IQR, 0.2-1.0]), vs extravascular VCD (2.0 minutes [IQR, 1.0-2.0]; P <.001) and closure device failure was also significantly lower among those with intravascular vs extravascular VCD (80 patients [5.3%], vs 184 patients [12.2%]; P < .001). CONCLUSIONS AND RELEVANCE: In patients undergoing transfemoral coronary angiography, VCDs were noninferior to manual compression in terms of vascular access-site complications and reduced time to hemostasis.
