Five-year clinical outcome of multicenter randomized trial comparing amphilimus - with paclitaxel-eluting stents in de novo native coronary artery lesions.

OBJECTIVES: Long-term data from randomized studies on polymer-free stents are scarce. Long-term data of Cre8 amphilimus eluting stent are still not available. We sought to investigate contribution of a polymer-free design versus a permanent-polymer one on the long-term. METHODS AND RESULTS: Patients undergoing percutaneous coronary intervention for de novo lesions were randomized 1:1 to Cre8 or Taxus Liberté (323 overall, 126 Cre8). Original primary endpoint (6-month angiographic in-stent late lumen loss) already demonstrated the superiority of Cre8 vs Taxus (0.14 + 0.36 mm vs. 0.34 + 0.40 mm; p < 0.001). Secondary endpoints were the device oriented composite endpoint (DOCE), patient oriented composite endpoint (POCE) up to 5-year. Long-term follow-up data confirmed the superiority shown by Cre8 in the analysis of the angiographic endpoint at 6-month, especially in the diabetic patients, where the device strongly reduced the clinical difference with non-diabetic. Landmark analysis demonstrated that the incidence of DOCE after 1-year and up to 5-year follow up was significantly lower in patients implanted with Cre8 AES (2.1% Cre8 vs. 9.3% Taxus, p = 0.009). While no differences were found in terms of DOCE rate among diabetic and non-diabetic patients treated with the Cre8 AES (HR 1.039; 95%CI 0.320-3.374), this was not true for Taxus (HR 2.64; 95%CI 1.112-6.278). CONCLUSIONS: Cre8 showed favourable safety and efficacy results versus Taxus at 5-years follow-up, with a superior clinical performance for the DOCE endpoint from 1 to 5 years. Cre8, differently from Taxus, has been able to strongly reduce the differences in clinical outcome between diabetic and non-diabetic up to 5 years, suggesting the higher efficacy of Cre8 in the treatment of diabetic patients.

Facilitated Data Relay and Effects on Treatment of Severe Aortic Stenosis in Europe.

Background Many patients with severe aortic stenosis are referred late with advanced symptoms or inappropriately denied intervention. The objective was to investigate whether a structured communication to referring physicians (facilitated data relay) might improve the rate and timeliness of intervention. Methods and Results A prospective registry of consecutive patients with severe aortic stenosis at 23 centers in 9 European countries with transcatheter as well as surgical aortic valve replacement being available was performed. The study included a 3-month documentation of the status quo (phase A), a 6-month intervention phase (implementing facilitated data relay), and a 3-month documentation of a legacy effect (phase-B). Two thousand one hundred seventy-one patients with severe aortic stenoses were enrolled (phase A: 759; intervention: 905; phase-B: 507). Mean age was 77.9±10.0 years, and 80% were symptomatic, including 52% with severe symptoms. During phase A, intervention was planned in 464/696 (67%), 138 (20%) were assigned to watchful waiting, 8 (1%) to balloon aortic valvuloplasty, 60 (9%) were listed as not for active treatment, and in 26 (4%), no decision was made. Three hundred sixty-three of 464 (78%) patients received the planned intervention within 3 months. Timeliness of the intervention improved as shown by the higher number of aortic valve replacements performed within 3 months (59% versus 51%, P=0.002) and a significant decrease in the time to intervention (36±38 versus 30±33 days, P=0.002). Conclusions A simple, low-cost, facilitated data relay improves timeliness of treatment for patients diagnosed with severe aortic stenosis, resulting in a shorter time to transcatheter aortic valve replacement. This effect was mainly driven by a significant improvement in timeliness of intervention in transcatheter aortic valve replacement but not surgical aortic valve replacement.

Symptoms, disease severity and treatment of adults with a new diagnosis of severe aortic stenosis.

OBJECTIVE: Contemporary data on patients with previously undiagnosed severe aortic stenosis (AS) are scarce. We aimed to address this gap by gathering data from consecutive patients diagnosed with severe AS on echocardiography. METHODS: This was a prospective, multicentre, multinational, registry in 23 tertiary care hospitals across 9 European countries. Patients with a diagnosis of severe AS were included using echocardiography (aortic valve area (AVA) <1 cm2, indexed AVA <0.6 cm2/m2, maximum jet-velocity (Vmax) >4 m/s and/or mean transvalvular gradient >40 mm Hg). RESULTS: The 2171 participants had a mean age of 77.9 years and 48.0% were female. The mean AVA was 0.73 cm2, Vmax4.3 m/s and mean gradient 47.1 mm Hg; 62.1% had left ventricular hypertrophy and 27.3% an ejection fraction (EF) <50%. 1743 patients (80.3%) were symptomatic (shortness-of-breath 91.0%; dizziness 30.2%, chest pain 28.9%). Patients had a EuroSCORE II of 4.0; 25.3% had a creatinine clearance <50 mL/min, and 3.2% had an EF <30%. Symptomatic patients were older and had more comorbidities than asymptomatic patients. Despite European Society of Cardiology 2017 valvular heart disease guideline class I recommendation, in only 76.2% a decision was made for an intervention (transcatheter 50.4%, surgical aortic valve replacement 25.8%). In asymptomatic patients, 57.7% with a class I/IIa indication were scheduled for a procedure, while 36.3% patients without an indication had their valve replaced. CONCLUSIONS: The majority of patients with severe AS presented at an advanced disease stage. Management of severe AS remained suboptimal in a significant proportion of contemporary patients with severe AS. TRIAL REGISTRATION NUMBER: NCT02241447;Results.

A multicenter post-marketing evaluation of the Elixir DESolve® Novolimus-eluting bioresorbable coronary scaffold system: First results from the DESolve PMCF study.

OBJECTIVES: To date, experience with bioresorbable scaffolds (BRS) that elute agents other than everolimus is limited. Thus, a post-marketing clinical follow-up study was conducted to evaluate the continued safety and effectiveness of the DESolve® NOVOLIMUS™ Eluting BRS as treatment for patients with stable coronary artery disease. BACKGROUND: The DESolve BRS combines a poly-l-lactide-based backbone with a biodegradable polylactide-based polymer and Novolimus, a macrocyclic lactone mTOR inhibitor. METHODS: One hundred and two patients (mean age 62 years, 77.5% male) were enrolled at 10 European sites. Comparison of baseline and post-procedural angiographic assessment was performed, and a device-oriented composite endpoint (comprising cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization) and rate of scaffold thrombosis at 12 months were examined. RESULTS: The device was successfully delivered and deployed in 98.2% (107/109) of the lesions, with two failures to cross the lesion. A total of 100 patients (109 lesions) were treated with a DESolve BRS. Post-procedural angiographic assessment indicated an in-scaffold acute gain of 1.54 ± 0.44 mm, with a reduction in % diameter stenosis from 61.00 ± 11.29 to 12.69 ± 0.44. At 12 months, the device-oriented composite endpoint had occurred in 3.0% (3/100) of patients, with 1.0% (1/100) experiencing scaffold thrombosis and myocardial infarction and 3.0% (3/100) undergoing target lesion revascularization. There were no cardiac deaths. CONCLUSIONS: Results through 12 months indicate that the DESolve BRS is a safe and effective treatment for coronary lesions, though larger, long-term prospective studies are needed.

The role of echocardiography and CT angiography in transcatheter aortic valve implantation patients.

The transcatheter aortic valve implantation (TAVI) consist an alternative treatment in patients with severe aortic stenosis. Multimodality imaging using transthoracic echocardiography (TTE) or transesophageal echocardiography (TOE) and multislice CT (MSCT) constitute cornerstone techniques for the pre-operative management, peri-procedural guidance, follow up and recognition of possible transcatheter valve related complications. CT angiography is much more accurate regarding the total definition of aortic annulus diameter and circumferential area. Two-dimensional (2D) echocardiography, underestimates the aortic valve annulus diameter compared to 3D imaging techniques (MSCT, MRI and 3D TOE). Three-dimensional TOE imaging provides measurements of the aortic valve annulus similar to those delivered by MSCT. The pre-procedural MSCT constitutes the gold standard modality minimizing the presence of paravalvular aortic regurgitation, one of the most frequent complications. TOE/TTE and MSCT performance could predict the possibility of pacemaker implantation post-procedural. The presence of a new transient or persisting MR can be assessed well by TOE. Both TTE and TOE, consist initially the basic examination for post TAVI evaluation. In case of transcatheter heart valve failure, the MSCT could be used as additional imaging technique.

Reducing Patient Radiation Dose With Image Noise Reduction Technology in Transcatheter Aortic Valve Procedures.

X-ray radiation exposure is of great concern for patients undergoing structural heart interventions. In addition, a larger group of medical staff is required and exposed to radiation compared with percutaneous coronary interventions. This study aimed at quantifying radiation dose reduction with implementation of specific image noise reduction technology (NRT) in transcatheter aortic valve implantation (TAVI) procedures. We retrospectively analyzed 104 consecutive patients with TAVI procedures, 52 patients before and 52 after optimization of x-ray radiation chain, and implementation of NRT. Patients with 1-step TAVI and complex coronary intervention, or complex TAVI procedures, were excluded. Before the procedure, all patients received a multislice computed tomography scan, which was used to size aortic annulus, select the optimal implantation plane, valve type and size, and guide valve implantation using a software tool. Air kerma and kerma-area product were compared in both groups to determine patient radiation dose reduction. Baseline parameters, co-morbidity, or procedural data were comparable between groups. Mean kerma-area product was significantly lower (p <0.001) in the NRT group compared with the standard group (60 ± 39 vs 203 ± 106 Gy × cm(2), p <0.001), which corresponds to a reduction of 70%. Mean air kerma was reduced by 64% (494 ± 360 vs 1,355 ± 657 mGy, p <0.001). In conclusion, using optimized x-ray chain combined with specific image noise reduction technology has the potential to significantly reduce by 2/3 radiation dose in standard TAVI procedures without worsening image quality or prolonging procedure time.

Prospective Multicenter Evaluation of the Direct Flow Medical Transcatheter Aortic Valve System: 12-Month Outcomes of the Evaluation of the Direct Flow Medical Percutaneous Aortic Valve 18F System for the Treatment of Patients With Severe Aortic Stenosis (DISCOVER) Study.

OBJECTIVES: The aim of this study was to assess the 1-year outcome after transcatheter aortic valve replacement (TAVR) of the Direct Flow Medical (DFM) valve in patients with severe symptomatic aortic stenosis who were contraindicated or high risk for surgery. BACKGROUND: The DFM transcatheter heart valve is a new-generation, nonmetallic aortic valve with a pressurized support structure and conformable double-ring annular sealing delivered through an 18-F sheath. The device allows repositioning, retrieval, and assessment of valve performance before permanent implantation. METHODS: A prospective multicenter European registry was set up to determine the safety and performance of the valve in 100 consecutive patients (10 centers). Echocardiographic and angiographic data were evaluated by an independent core laboratory, and adverse events were adjudicated by a clinical events committee using Valve Academic Research Consortium criteria. RESULTS: Patients were 83.1 ± 5.9 years of age and had a logistic EuroSCORE of 22.5 ± 11.3% and a Society of Thoracic Surgeons score of 9.7 ± 8.7%. Correct valve positioning was obtained in 99% of cases with a combined 30-day safety endpoint at 10%, including major stroke in 5.0%, major vascular complications in 2.0%, and death in 1%. At 12 months, 95% of patients were in New York Heart Association functional class I or II. Freedom from any death was 90%, and freedom from any death or major stroke was 85%. Echocardiography demonstrated none/trace to mild aortic regurgitation in 100% of patients and an unchanged mean aortic gradient of 12.2 ± 6.6 mm Hg and effective orifice area of 1.6 ± 0.4 cm(2). CONCLUSIONS: At 1 year, the DFM transcatheter heart valve had durable hemodynamics. This study demonstrates that the low rate of early complications and the low risk of significant aortic regurgitation translated into midterm clinical benefit.

Transcatheter valve-in-ring implantation of a repositionable valve system for treatment of severe mitral regurgitation.

INTRODUCTION: Years after mitral valve surgery, progressive degeneration of reconstructed mitral valves or bioprostheses might lead to severe mitral valve regurgitation. Patients with significant comorbidity, or impaired left ventricular function are poor candidates for redo surgery at an acceptable risk at that later time point. METHODS AND RESULTS: This study reports the first-in-man transapical valve-in-ring implantations in the mitral position of the fully repositionable Lotus valve system approved for transcatheter aortic valve replacement in Europe. Transapical valve-in-ring implantations with this valve system were successfully performed in a 64-year-old female, and a 53-year-old male patient. Both patients were NHYA class IV, and carried an unacceptably high risk of cardiac surgery due to clinical condition and comorbidity. The first patient was successfully implanted a 25 mm valve, improved to NYHA class II, and was discharged 2 weeks after the procedure. The second patient required a short episode of cardiopulmonary resuscitation after valve implantation (27 mm), and was placed on veno-venous ECMO for 24 hr to improve oxygenation. He developed stroke on day 7, and deceased from fatal, toxic rhabdomyolysis 13 days after the procedure. CONCLUSION: Transapical valve-in-ring implantation of the repositionable Lotus valve system in the mitral position is a feasible and promising option that merits further evaluation. © 2015 Wiley Periodicals, Inc.

Use of a balloon-expandable transfemoral sheath in a TAVI cohort with complex access site - a propensity score matched analysis.

AIMS: In patients undergoing transcatheter aortic valve implantation (TAVI), the high prevalence of peripheral artery disease (PAD) limits femoral access and increases vascular complications that are associated with mortality and morbidity. Our study assessed the ability of a balloon-expandable large-bore vascular sheath to increase access-site availability and to reduce vascular complications. METHODS AND RESULTS: Among 257 patients from two centres, 43 patients underwent transfemoral TAVI with the use of the SoloPath balloon-expandable sheath due to complex iliofemoral access anatomy. Propensity score matching (2:1) was performed except for the sheath to femoral artery ratio (SFAR). Compared to standard sheath patients, we found no significant difference in 30-day and one-year mortality (SoloPath vs. standard sheath, 9.3% vs. 3.5%; p=0.2, and 18.6% vs. 23.3%; p=0.7), major vascular complications (9.3% vs. 4.7%; p=0.3), and major bleeding (9.3% vs. 10.5%; p=0.5) in the cohort with the balloon-expandable sheath. CONCLUSIONS: The use of a balloon-expandable large-bore sheath in patients with a high risk for vascular complications due to complex access-site anatomy proved to be feasible and safe. However, circumferential calcifications and sheath-to-artery ratios account for vascular access complications even in patients treated with the balloon-expandable sheath.

Fifteen-year experience with carotid artery stenting (from the carotid artery stenting-registry of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte).

To date only sparse data are available on trends and changes in indications, patient's characteristics, and clinical outcome of patients undergoing carotid artery stenting (CAS) in clinical practice. From February 1996 to December 2010, 6,116 CAS procedures were performed in 5,976 patients at 36 hospitals within the prospective, multicenter CAS registry of the Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte. Median age of patients was 71 years, 71.6% were men; a symptomatic stenosis was treated in 50.3% and an embolic protection device (EPD) was used in 82.5% of the patients. The overall hospital mortality or stroke rate was 3.1%. Stroke or in-hospital death occurred in 4.0% in symptomatic patients and in 2.2% in asymptomatic patients. In a logistic regression model, independent predictors of in-hospital death or stroke were heart failure (odds ratio [OR] 2.03, 95% confidence interval [CI] 1.22 to 3.36, p = 0.006), symptomatic stenosis (OR 1.52, 95% CI 1.05 to 2.18, p = 0.03), and age (OR per 10 years 1.46, 95% CI 1.17 to 1.81, p <0.001). The use of an EPD was significantly associated with a lower rate of death or stroke in the registry (OR 0.45, 95% CI 0.26 to 0.78, p = 0.004). From 1996 to 2010, mean age of patients increased by 4.1 years (p <0.001), the proportion of male patients decreased from 82.4% to 70.2% (p = 0.07), the proportion of symptomatic stenoses decreased (84.6% to 24.7%, p <0.001), and the use of EPDs increased from 1.4% to 97.2% (p <0.001). Comparing 2 periods from 1996 to 2003 and 2004 to 2010, a numeric decrease in the in-hospital stroke or death rate was seen in symptomatic (4.7% vs 3.5%, p = 0.11), and in asymptomatic patients (2.9% vs 2.1%, p = 0.27) undergoing CAS, which did not reach statistical significance. In conclusion, the proportion of symptomatic carotid artery stenoses decreased significantly; EPDs established as a standard tool and a numeric decrease of in-hospital stroke or death was seen in asymptomatic and symptomatic patients undergoing CAS in clinical practice over the last 15 years.

Use of drug-eluting stents in acute myocardial infarction with persistent ST-segment elevation: results of the ALKK PCI-registry.

BACKGROUND: Drug-eluting stents (DES) reduce the rate of in-stent restenosis (ISR) and target vessel revascularization significantly when compared with bare metal stents (BMS). Their beneficial effects have been demonstrated in patients with acute myocardial infarction also, but the use of DES in the latter population seems to be still limited in clinical practice. METHODS AND RESULTS: From January 2006 to December 2011, 25,424 patients with ST-elevation myocardial infarction were enrolled in the German ALKK PCI-registry. In 5,467 patients (21.5 %), a DES was implanted in the culprit segment, in 16,911 patients (66.5 %) a BMS, and 2,959 patients (11.6 %) received neither DES nor BMS. The rates of DES for typical subgroups were 31.7 % in patients with diabetes, 36.6 % in unprotected left main stenosis, 32.4 % in ostial lesions, 32.0 % for a stent length >15 mm, 26.2 % for a stent diameter ≤3 mm, and 58.5 % for ISR. There was a wide range in the use of DES between the different ALKK hospitals with a minimum of 2.3 % and a maximum of 58.3 % for the total study period (median 22.0 %, quartiles 14.6 and 37.5 %). CONCLUSIONS: Despite convincing data for the use of DES in patients with STEMI, there is still an underuse of DES in this clinical setting in Germany. This is particularly worrying for the subgroups of patients and lesions with a high risk of restenosis. Further efforts are needed to reduce the skepticism about DES and to improve guideline adherent treatment.

Comparison of the effectiveness of transcatheter aortic valve implantation in patients with stenotic bicuspid versus tricuspid aortic valves (from the German TAVI Registry).

Patients with bicuspid aortic valves (BAVs) are considered a relative contraindication to transcatheter aortic valve implantation (TAVI). One of the main reasons is the presumed risk for residual aortic regurgitation (AR). However, case reports and small case series have suggested that TAVI can be successfully performed with acceptable clinical outcomes in high-risk patients with BAV. Within the large German TAVI Registry, we sought to evaluate TAVI in older high-risk patients with BAV. From January 2009 to June 2010, a total of 1,424 patients with severe aortic stenosis undergoing TAVI were prospectively enrolled into the German TAVI Registry. For the present analysis, patients with valve-in-valve procedures were excluded and those with BAV (n = 38, 3%) were compared with those with tricuspid aortic valve (TAV; n = 1357, 97%). Patient characteristics did not markedly differ and procedural success was very high in both groups. There was a higher rate of relevant AR (≥II) after TAVI among patients with BAV (25 vs 15%, p = 0.05), whereas pacemakers were more often implanted in patients with TAV (17% vs 35%, p = 0.02). Thirty-day mortality rate was similar in both cohorts (11% vs 11%). In a Cox proportional regression analysis, BAV was not associated with higher 1-year mortality rate (hazard ratio 0.64, 95% confidence interval 0.29 to 1.41). In selected patients with BAV, TAVI can be performed with a satisfactory clinical result. Although the risk for relevant AR seems to be greater among patients with BAV, 30-day and 1-year mortality rates were not elevated compared with patients with TAV.

Prospective multicenter evaluation of the direct flow medical transcatheter aortic valve.

OBJECTIVES: The study sought a prospective multicenter nonrandomized evaluation of the Direct Flow Medical (DFM) system for the treatment of severe aortic stenosis. BACKGROUND: The DFM transcatheter aortic valve system is a nonmetallic design with a pressurized support structure that allows precise positioning, retrieval, and assessment of valve performance prior to permanent implantation. METHODS: One hundred high surgical risk patients with severe aortic stenosis were evaluated for the primary endpoint. There were 75 patients in the group evaluable for the secondary endpoints and 25 in the pre-specified roll-in training phase. Echocardiographic and angiographic data were evaluated by an independent core laboratory and adverse events adjudicated by clinical event committee and classified according to Valve Academic Research Consortium (VARC) criteria. RESULTS: There was 99% freedom from all cause mortality at 30 days (primary endpoint). VARC criteria defined 30 day combined freedom from patient safety event rate was 91% and overall device success was 93%. The post-implantation echocardiography results demonstrated mild or no aortic regurgitation in 99% (73 of 74) with a mean gradient of 12.6 ± 7.1 mm Hg (n = 72) and effective orifice area of 1.50 ± 0.56 cm(2) and New York Heart Association functional class was I or II in 92% of cases. CONCLUSIONS: The present study demonstrates the safety and efficacy of the DFM system in surgical high risk patients with severe aortic stenosis and complex anatomy aortic regurgitation was less than moderate in 99% of patients.

Intra-aortic balloon pump in patients with acute myocardial infarction complicated by cardiogenic shock: results of the ALKK-PCI registry.

AIMS: The recommendation for the use of the intra-aortic balloon pump (IABP) as adjunct in patients with cardiogenic shock undergoing primary PCI in current guidelines is controversial. We sought to investigate the use and impact of the outcome of IABP in current practice of percutaneous coronary interventions in Germany. METHODS AND RESULTS: Between January 2006 and December 2011, a total of 55,008 consecutive patients with acute coronary syndromes undergoing PCI in 41 hospitals were enrolled into the prospective Arbeitsgemeinschaft Leitende Kardiologische Krankenhausärzte registry. Of these, 22,039 had STEMI and 32,969 had NSTEMI, and cardiogenic shock was observed in 1,435 (6.5 %) and 478 (1.4 %), respectively. Of the total of 1,913 patients with shock, 487 (25.5 %) were treated with IABP. In-hospital mortality with and without IABP was 43.5 and 37.4 %. In the multivariate analysis, the use of IABP was associated with a strong trend for an increased mortality (odds ratio 1.45, 95 % CI 1.15-1.84). CONCLUSION: In the current clinical practice in Germany, IABP is used only in one quarter of patients with cardiogenic shock treated with primary PCI. We observed no benefit of IABP on outcome, which supports the findings of the randomized IABP-Shock II trial.

Age-stratified baseline and outcome characteristics of patients undergoing transcatheter aortic valve implantation: results from the German multicenter registry.

OBJECTIVES: To analyze age dependencies in patients currently undergoing transcatheter aortic valve implantation (TAVI) based on the German TAVI registry. BACKGROUND: TAVI is a promising, less invasive treatment option for surgical high-risk patients with symptomatic aortic valve stenosis, with the majority being octogenarians treated so far. Younger patients with significant co-morbidities are now increasingly considered for this procedure, but little is known about this population. METHODS: The German TAVI registry is an ongoing non-randomized national multicenter study. Consecutive patients who underwent TAVI between January 2009 and June 2010 were included in this analysis. We compared baseline characteristics, procedural characteristics, and short-term clinical outcome up to 30-day follow-up. RESULTS: A total of 1386 patients were divided into 4 roughly equally-sized groups: group A, n = 347, mean age 73.4 ± 4.5 years; group B, n = 350, mean age 80.6 ± 1.1 years; group C, n = 382, mean age 84.5 ± 1.1 years; and group D, n = 312, mean age 88.9 ± 2.2 years. Patient characteristics varied significantly, with more co-morbidities in younger patients. Technical success rates were similar in all groups (96.6%-97.7%; P=NS). 30-day major adverse event rates were similar with an all-cause mortality rate of 7.2% (A), 7.1% (B), 9.7% (C) and 8.7% (D; P=NS). Postprocedural improvement of both New York Heart Association and self-reported health status was significant in all groups, with significantly better improvements in the categories 'mobility' and 'ability for self-care' in younger patients. CONCLUSION: TAVI appears to be similarly safe and effective across different age groups with currently applied enrollment criteria, but younger patients present with significantly more co-morbidities. All patient populations experience functional improvements, but this is particularly pronounced for younger patients.

The impact of peripheral arterial disease on early outcome after transcatheter aortic valve implantation: results from the German Transcatheter Aortic Valve Interventions Registry.

BACKGROUND: A significant proportion of patients undergoing transcatheter aortic valve implantation (TAVI) have concomitant peripheral arterial disease (PAD), which plays a crucial role in the preinterventional selection process of determining an optimal vascular access site. The aim of our study was to determine the impact of PAD on clinical outcome after TAVI in a real-world setting. METHODS: A total of 1,315 patients (mean logistic European System for Cardiac Operative Risk Evaluation 20.6% ± 13.7%) underwent TAVI in 27 centers and were included in the prospective German TAVI Registry. RESULTS: Of the 1,315 patients with TAVI, 330 (25.1%) had PAD. These patients had a higher logistic European System for Cardiac Operative Risk Evaluation score (27.7% ± 16.0% vs 18.3% ± 12.0%, P < .0001), mainly attributed to more frequent and severe comorbidities. Compared with patients without PAD, patients with PAD had a higher rate of vascular complications (28.5% vs 20.7%, P < .01), dialysis-dependent renal failure (11.2% vs 5.4%, P < .001), myocardial infarction (1.2% vs 0.3%, P < .05), and, subsequently, 30-day mortality (12.7% vs 6.9%, P < .001). Choosing a surgical approach, for example, transapical access, did not reduce the periprocedural risk associated with PAD; in-hospital mortality was 15.7% for surgical and 10.5% for percutaneous patients with TAVI having PAD (P < .001). In a multivariate regression analysis, PAD was an independent predictor of 30-day mortality (hazard ratio 1.8, 95% CI 1.2-2.7, P = .004) after TAVI. CONCLUSIONS: In this real-world TAVI Registry, PAD was an independent predictor of mortality in patients with percutaneous and surgical TAVI, including vascular complications. Assessment of PAD should play a crucial role in the preinterventional selection process, regardless of the access strategy.
