Impact of the COVID-19 Pandemic on Global TAVR Activity: The COVID-TAVI Study.

BACKGROUND: The COVID-19 pandemic adversely affected health care systems. Patients in need of transcatheter aortic valve replacement (TAVR) are especially susceptible to treatment delays. OBJECTIVES: This study sought to evaluate the impact of the COVID-19 pandemic on global TAVR activity. METHODS: This international registry reported monthly TAVR case volume in participating institutions prior to and during the COVID-19 pandemic (January 2018 to December 2021). Hospital-level information on public vs private, urban vs rural, and TAVR volume was collected, as was country-level information on socioeconomic status, COVID-19 incidence, and governmental public health responses. RESULTS: We included 130 centers from 61 countries, including 65,980 TAVR procedures. The first and second pandemic waves were associated with a significant reduction of 15% (P < 0.001) and 7% (P < 0.001) in monthly TAVR case volume, respectively, compared with the prepandemic period. The third pandemic wave was not associated with reduced TAVR activity. A greater reduction in TAVR activity was observed in Africa (-52%; P = 0.001), Central-South America (-33%; P < 0.001), and Asia (-29%; P < 0.001). Private hospitals (P = 0.005), urban areas (P = 0.011), low-volume centers (P = 0.002), countries with lower development (P < 0.001) and economic status (P < 0.001), higher COVID-19 incidence (P < 0.001), and more stringent public health restrictions (P < 0.001) experienced a greater reduction in TAVR activity. CONCLUSIONS: TAVR procedural volume declined substantially during the first and second waves of the COVID-19 pandemic, especially in Africa, Central-South America, and Asia. National socioeconomic status, COVID-19 incidence, and public health responses were associated with treatment delays. This information should inform public health policy in case of future global health crises.

[Update Valvular Heart Disease: Heart Team Decision-Making Based on Patient Examples]. / Update valvuläre Herzkrankheiten: Entscheidungen im interdisziplinären Herzteam anhand von Beispielen.

INTRODUCTION: In Europe, mitral regurgitation and aortic stenosis are the most common valve lesions requiring interventions. In advanced stages, these valve pathologies affect patients' quality of life and prognosis. The prevalence of mitral regurgitation and aortic stenosis is increasing with age. In view of an aging population and the comorbidities associated with age, these valve defects represent an increasing challenge to health care providers. Nowadays, surgical as well as catheter-based treatment options are available to treat affected patients. Therapeutic strategies suitable to the individual patient should be discussed in interdisciplinary heart teams. The aim of the present article is to give an overview of possible guideline-conform heart team decisions based on patient examples.

Association of chocolate consumption with neurological and cardiovascular outcomes in atrial fibrillation: data from two Swiss atrial fibrillation cohort studies (Swiss-AF and BEAT-AF).

AIM: To assess the associations of chocolate consumption with neurocognitive function, brain lesions on magnetic resonance imaging (MRI), and cardiovascular outcome in patients with atrial fibrillation (AF). METHODS: We analysed data from patients of two prospective multicentre Swiss atrial fibrillation cohort studies (Swiss-AF) and (BEAT-AF). Assessments of MRI findings and neurocognitive function were performed only in the Swiss-AF population (in 1727 of 2415 patients [71.5%] with a complete data set), as patients enrolled in BEAT-AF were not systematically evaluated for these outcomes. Otherwise, the two cohorts had an equivalent set of clinical assessments. Clinical outcome analysis was performed in 3931 patients of both cohorts. Chocolate consumption was assessed by questionnaire. Patients were categorised as no/low chocolate consumption (No/Low-Ch) ≤1 servings/week, moderate chocolate consumption (Mod-Ch) >1-6 servings/week, and high chocolate consumption (High-Ch) >6 servings/week, respectively. Brain lesions were evaluated by MRI. Assessment of cognitive function was performed by neurocognitive functional testing and included global cognition measurement with a cognitive construct score. Cerebral MRI and cognition were evaluated at baseline. Cross-sectional associations between chocolate consumption and MRI findings were analysed by multivariate logistic regression models and associations with neurocognitive function by multivariate linear regression models. Clinical outcome events during follow-up were recorded and assessed by a clinical event committee. The associations between chocolate consumption and clinical outcomes were evaluated by Cox regression models. The median follow-up time was 6 years. RESULTS: Chocolate consumption was not associated with prevalence or volume of vascular brain lesions on MRI, nor major adverse cardiac events (ischaemic stroke, myocardial infarction, cardiovascular death). However, No/Low-Ch was independently associated with a lower cognitive construct score compared to Mod-Ch (No/Low-Ch vs. Mod-Ch: coeff. -0.05, 95% CI -0.10-0), whereas other neurocognitive function tests were not independently associated with chocolate consumption categories. In addition, there was a higher risk of heart failure hospitalisation (No/Low-Ch vs. Mod-Ch: HR 1.24, 95% CI 1.01-1.52) and of all-cause mortality (No/Low-Ch vs. Mod-Ch: HR 1.29, 95% CI 1.06-1.58) in No/Low-Ch compared to Mod-Ch. No significant associations with the evaluated outcomes were observed when High-Ch was compared to Mod-Ch. CONCLUSION: While chocolate consumption was not associated with MRI findings and major adverse cardiac events in an atrial fibrillation population, No/Low-Ch was associated with a lower cognitive construct score, higher risk of heart failure hospitalisation and increased all-cause mortality compared to Mod-Ch.

Sex-specific inequalities in the use of drug-coated balloons for small coronary artery disease: a report from the BASKET-SMALL 2 trial.

BACKGROUND AND OBJECTIVES: Recent data have established non-inferiority of drug-coated balloons (DCB) compared to drug-eluting stents (DES) for treatment of small-vessel coronary artery disease. Since coronary vessels in women might have anatomical and pathophysiological particularities, the safety of the DCB strategy among women compared to men needs to be assessed in more detail. METHODS: In BASKET-SMALL 2, patients with de novo lesions in coronary vessels < 3 mm and an indication for percutaneous coronary intervention were randomly allocated (1:1) to DCB vs. DES after successful lesion preparation. The primary objective of the randomized trial was to establish non-inferiority of DCB vs. DES regarding major adverse cardiac events (MACE; i.e., cardiac death, non-fatal myocardial infarction, and target vessel revascularization) after 12 months. The aim of the current sub-analysis is to evaluate whether the DCB strategy is equally safe among women and men after 12 and 36 months. RESULTS: Among 758 randomized patients, 382 were assigned to DCB (23% women) and 376 to DES (30% women). In general, women were older, had more often diabetes mellitus and renal insufficiency, and presented more often with an acute coronary syndrome, whereas men were more often smokers, had multivessel disease and a previous history of acute myocardial infarction, and received a treatment with a statin. After 3 years, the primary clinical end point was not significantly different between groups (13% women vs. 16% men, HR 0.82; 95% CI 0.52-1.30; p = 0.40). There was no interaction between sex and coronary intervention strategy regarding MACE at 36 months (10% women vs. 16% men in DCB, 16% women vs. 15% men in DES; pinteraction = 0.31). CONCLUSION: In small native coronary artery disease, there was no statistically significant effect of sex on the difference between DCB and DES regarding MACE up to 36 months.

Impact of chronic kidney disease and diabetes on clinical outcomes in women undergoing PCI.

BACKGROUND: For women undergoing drug-eluting stent (DES) implantation, the individual and combined impact of chronic kidney disease (CKD) and diabetes mellitus (DM) on outcomes is uncertain. AIMS: We sought to assess the impact of CKD and DM on prognosis in women after DES implantation. METHODS: We pooled patient-level data on women from 26 randomised controlled trials comparing stent types. Women receiving DES were stratified into 4 groups based on CKD (defined as creatine clearance <60 mL/min) and DM status. The primary outcome at 3 years after percutaneous coronary intervention was the composite of all-cause death or myocardial infarction (MI); secondary outcomes included cardiac death, stent thrombosis and target lesion revascularisation. RESULTS: Among 4,269 women, 1,822 (42.7%) had no CKD/DM, 978 (22.9%) had CKD alone, 981 (23.0%) had DM alone, and 488 (11.4%) had both conditions. The risk of all-cause death or MI was not increased in women with CKD alone (adjusted hazard ratio [adj. HR] 1.19, 95% confidence interval [CI]: 0.88-1.61) nor DM alone (adj. HR 1.27, 95% CI: 0.94-1.70), but was significantly higher in women with both conditions (adj. HR 2.64, 95% CI: 1.95-3.56; interaction p-value <0.001). CKD and DM in combination were associated with an increased risk of all secondary outcomes, whereas alone, each condition was only associated with all-cause death and cardiac death. CONCLUSIONS: Among women receiving DES, the combined presence of CKD and DM was associated with a higher risk of the composite of death or MI and of any secondary outcome, whereas alone, each condition was associated with an increase in all-cause and cardiac death.

Value of Periprocedural Electrophysiology Testing During Transcatheter Aortic Valve Replacement for Risk Stratification of Patients With New-Onset Left Bundle-Branch Block.

Background Despite being the most frequent complication following transcatheter aortic valve replacement (TAVR), optimal management of left bundle-branch block (LBBB) remains unknown. Electrophysiology study has been proposed for risk stratification. However, the optimal timing of electrophysiology study remains unknown. We aimed to investigate the temporal dynamics of atrioventricular conduction in patients with new-onset LBBB after TAVR by performing serial electrophysiology study and to deduce a treatment strategy. Methods and Results We assessed consecutive patients undergoing TAVR via His-ventricular interval measurement prevalve and postvalve deployment and the day after TAVR. Infranodal conduction delay was defined as a His-ventricular interval >55 milliseconds. Among 107 patients undergoing TAVR, 53 patients (50%) experienced new-onset LBBB postvalve deployment and infranodal conduction delay was noted in 24 of 53 patients intraprocedurally (45%). LBBB resolved the day after TAVR in 35 patients (66%). In patients with new-onset LBBB postvalve deployment and no infrahisian conduction delay intraprocedurally, the His-ventricular interval did not prolong in any patient to >55 milliseconds the following day. Overall, 4 patients (7.5%) with new-onset LBBB after TAVR were found to have persistent infrahisian conduction delay 24 hours after TAVR. During 30-day follow-up, 1 patient (1.1%) with new LBBB and a normal His-ventricular interval after TAVR developed new high-grade atrioventricular block. Conclusions Among patients with new-onset LBBB postvalve deployment, infrahisian conduction delay can safely be excluded intraprocedurally, suggesting that early intracardiac intraprocedural conduction studies may be of value in these patients.

First-in-man concomitant mitral valve replacement and coronary artery bypass grafting using a single minimally invasive access.

We present the case of a 78-year-old woman suffering from coronary artery disease and secondary severe mitral valve regurgitation due to left ventricular and annular distention. The interdisciplinary heart team recommended a simultaneous hybrid procedure consisting of minimally invasive direct coronary artery bypass grafting with subsequent transapical mitral valve replacement using the Tendyne prosthesis via the same small anterolateral thoracotomy. The operation was performed using a heart-team approach with close collaboration between heart surgeons and cardiologists in the hybrid operating theatre. The intra- and postoperative courses were uneventful. Predischarge transthoracic echocardiography on postoperative day 8 revealed the immaculate functioning of the implanted valve without para- or transvalvular insufficiency, a mean gradient of 2 mmHg, no left ventricular outflow tract obstruction and a stable ejection fraction of 50%. The combination of minimally invasive direct coronary artery bypass grafting revascularization with concomitant transapical mitral valve replacement is feasible and enables a further step towards minimally invasive therapy, even in complex situations. It shows that the modern heart-team approach exceeds mere decision making and expands towards a hybrid treatment for patients.

Drug-Coated Balloon for Small Coronary Artery Disease in Patients With and Without High-Bleeding Risk in the BASKET-SMALL 2 Trial.

BACKGROUND: Patients at high-bleeding risk (HBR) undergoing percutaneous coronary intervention represent a challenging patient population. The use of drug-coated balloon (DCB) allows shorter duration of dual antiplatelet therapy compared with drug-eluting stents (DES) and reduces thrombotic risk due to the absence of a permanent implant. The present analysis aimed to investigate if the effect of DCB versus DES differed between patients with and without HBR treated with percutaneous coronary intervention in small coronary arteries. METHODS: This prespecified subgroup analysis of a multicenter, randomized, noninferiority trial included 758 patients with de novo lesions in coronary vessels <3 mm and an indication for percutaneous coronary intervention, randomized to DCB (n=382) or second-generation DES (n=376). Patients were followed over 3 years for major adverse cardiac events. RESULTS: Of the 758 patients randomized, 155 (20%) had HBR; these patients had higher mortality at 3 years (hazard ratio [95% CI], 3.09 [1.78-5.36]; P<0.001). Rates of major bleeding events were overall low but tended to be lower after DCB versus DES (1.6% versus 3.7%; P=0.064), were similar in patients with HBR (4.5% versus 3.4%) but less frequent in DCB-versus DES-treated patients without HBR (0.9% versus 3.8%). There was no difference in major adverse cardiac events between DCB and DES regardless of bleeding risk (HBR, hazard ratio: 1.16 [0.51-2.62]; P=0.719 versus non-HBR, 0.96 [0.62-1.49]; P=0.863). CONCLUSIONS: DCBs were similarly safe and effective as current-generation DES in the treatment of coronary arteries <3 mm, regardless of bleeding risk. In patients treated with DCB, there was a trend towards a reduction of severe bleeding events at 3 years. REGISTRATION: URL: https://www. CLINICALTRIALS: gov; Unique identifier: NCT01574534.

Drug-coated balloons for small coronary artery disease in patients with chronic kidney disease: a pre-specified analysis of the BASKET-SMALL 2 trial.

BACKGROUND: Data on the safety and efficacy of drug-coated balloon (DCB) compared to drug-eluting stent (DES) in patients with chronic kidney disease (CKD) are scarce, particularly at long term. This pre-specified analysis aimed to investigate the 3-year efficacy and safety of DCB versus DES for small coronary artery disease (< 3 mm) according to renal function at baseline. METHODS: BASKET-SMALL-2 was a large multi-center, randomized, controlled trial that tested the efficacy and safety of DCBs (n = 382) against DESs (n = 376) in small vessel disease. CKD was defined as eGFR < 60 ml/min/1.73m2. The primary endpoint was the composite of cardiac death, non-fatal myocardial infarction, and target vessel revascularization (MACE) during 3 years. RESULTS: A total of 174/758 (23%) patients had CKD, out of which 91 were randomized to DCB and 83 to DES implantation. The primary efficacy outcome during 3 years was similar in both, DCB and DES patients (HR 0.98; 95%-CI 0.67-1.44; p = 0.937) and patients with and without CKD (HR 1.18; 95%-CI 0.76-1.83; p = 0.462), respectively. Rates of cardiac death and all-cause death were significantly higher among patients with CKD but not affected by treatment with DCB or DES. Major bleeding events were lower in the DCB when compared to the DES group (12 vs. 3, HR 0.26; 95%-CI 0.07-0.92; p = 0.037) and not influenced by presence of CKD. CONCLUSIONS: The long-term efficacy and safety of DCB was similar in patients with and without CKD. The use of DCB was associated with significantly fewer major bleeding events (NCT01574534).

Safety and Efficacy of Drug-Coated Balloons Versus Drug-Eluting Stents in Acute Coronary Syndromes: A Prespecified Analysis of BASKET-SMALL 2.

BACKGROUND: Drug-coated balloons (DCBs) are an established treatment strategy for coronary artery disease. Randomized data on the application of DCBs in patients with an acute coronary syndrome (ACS) are limited. We evaluated the impact of clinical presentation (ACS versus chronic coronary syndrome) on clinical outcomes in patients undergoing DCB or drug-eluting stent (DES) treatment in a prespecified analysis of the BASKET-SMALL 2 trial (Basel Kosten Effektivitäts Trial-Drug-Coated Balloons Versus Drug-Eluting Stents in Small Vessel Interventions). METHODS: BASKET-SMALL 2 randomized 758 patients with small vessel coronary artery disease to DCB or DES treatment and followed them for 3 years regarding major adverse cardiac events (cardiac death, nonfatal myocardial infarction, and target vessel revascularization). RESULTS: Among 758 patients, 214 patients (28.2%) presented with an ACS (15 patients [7%], ST-segment-elevation myocardial infarction; 109 patients [50.9%], non-ST-segment-elevation myocardial infarction; 90 patients [42.1%], unstable angina pectoris). At 1-year follow-up, there was no significant difference in the incidence of the primary end point by randomized treatment in patients with ACS (hazard ratio, 0.50 [95% CI, 0.19-1.26] for DCB versus DES) or chronic coronary syndrome (hazard ratio, 1.29 [95% CI, 0.67-2.47] for DCB versus DES). There was no significant interaction between clinical presentation and treatment effect (P for interaction, 0.088). For cardiac death (P for interaction, 0.049) and nonfatal myocardial infarction (P for interaction, 0.010), a significant interaction between clinical presentation and treatment was seen at 1 year with lower rates of these secondary end points in patients with ACS treated by DCB. At 3 years, there were similar major adverse cardiac event rates throughout groups without significant interaction between clinical presentation and treatment (P for interaction, 0.301). All-cause mortality was higher in ACS compared with chronic coronary syndrome; however, there was no difference between DCB and DES irrespective of clinical presentation. CONCLUSIONS: In this subgroup analysis of the BASKET-SMALL 2 trial, there was no interaction between indication for percutaneous coronary intervention (acute versus chronic coronary syndrome) and treatment effect of DCB versus DES in patients with small vessel coronary artery disease.

Impact of Diabetes on Outcome With Drug-Coated Balloons Versus Drug-Eluting Stents: The BASKET-SMALL 2 Trial.

OBJECTIVES: The study sought to evaluate the impact of diabetes mellitus on 3-year clinical outcome in patients undergoing drug-coated balloon (DCB) or drug-eluting stent (DES) treatment for de novo lesions. BACKGROUND: For treatment of de novo coronary small vessel disease, DCBs are noninferior to DES. METHODS: In this prespecified analysis of a multicenter, randomized, noninferiority trial, including 758 patients with de novo lesions in coronary vessels <3 mm who were randomized 1:1 to DCB or DES and followed over 3 years for major adverse cardiac events (MACE) (cardiac death, nonfatal myocardial infarction [MI], and target vessel revascularization [TVR]), outcome was analyzed regarding the presence or absence of diabetes mellitus. RESULTS: In nondiabetic patients (n = 506), rates of MACE (DCB 13.0% vs DES 11.5%; hazard ratio [HR]: 1.24; 95% confidence interval [CI]: 0.73-2.09; P = 0.43), cardiac death (2.8% vs 2.9%; HR: 0.97; 95% CI: 0.32-2.92; P = 0.96), nonfatal MI (5.1% vs 4.8%; HR: 1.00; 95% CI: 0.44-2.28; P = 0.99), and TVR (8.8% vs 6.1%; HR: 1.64; 95% CI: 0.83-3.25; P = 0.16) were similar. In diabetic patients (n = 252), rates of MACE (19.3% vs 22.2%; HR: 0.82; 95% CI: 0.45-1.48; P = 0.51), cardiac death (8.8% vs 5.9%; HR: 2.01; 95% CI: 0.76-5.31; P = 0.16), and nonfatal MI (7.1% vs 9.8%; HR: 0.55; 95% CI: 0.21-1.49; P = 0.24) were similar in DCB and DES. TVR was significantly lower with DCBs vs DES (9.1% vs 15.0%; HR: 0.40; 95% CI: 0.17-0.94; P = 0.036; P = 0.011 for interaction). CONCLUSIONS: The rates of MACE are similar in DCBs and DES in de novo coronary lesions of diabetic and nondiabetic patients. In diabetic patients, need for TVR was significantly lower with DCB versus DES.

Transcatheter Aortic Valve Replacement With the LOTUS Edge System: Early European Experience.

OBJECTIVES: The aim of this study was to evaluate the short-term safety and efficacy of transcatheter aortic valve replacement (TAVR) with the LOTUS Edge system. BACKGROUND: The LOTUS Edge system was commercially re-released in April 2019. The authors report the first European experience with this device. METHODS: A multicenter, single-arm, retrospective registry was initiated to evaluate short-term clinical outcomes. Included cases are the first experience with this device and new implantation technique in Europe. Clinical, echocardiographic, and computed tomographic data were analyzed. Endpoints were defined according to Valve Academic Research Consortium-2 and were site reported. RESULTS: Between April and November 2019, 286 consecutive patients undergoing TAVR with the LOTUS Edge system at 18 European centers were included. The mean age and Society of Thoracic Surgeons score were 81.2 ± 6.9 years and 5.2 ± 5.4%, respectively. Nearly one-half of all patients (47.9%) were considered to have complex anatomy. Thirty-day major adverse events included death (2.4% [n = 7]) and stroke (3.5% [n = 10]). After TAVR, the mean aortic valve area was 1.9 ± 0.9 cm2, and the mean transvalvular gradient was 11.9 ± 5.7 mm Hg. None or trace paravalvular leak (PVL) occurred in 84.4% and moderate PVL in 2.0%. There were no cases of severe PVL. New permanent pacemaker (PPM) implantation was required in 25.9% among all patients and 30.8% among PPM-naive patients. CONCLUSIONS: Early experience with the LOTUS Edge system demonstrated satisfactory short-term safety and efficacy, favorable hemodynamic data, and very low rates of PVL in an anatomically complex cohort. New PPM implantation remained high. Further study will evaluate if increasing operator experience with the device and new implantation technique can reduce the incidence of PPM implantation.

Long-term efficacy and safety of drug-coated balloons versus drug-eluting stents for small coronary artery disease (BASKET-SMALL 2): 3-year follow-up of a randomised, non-inferiority trial.

BACKGROUND: In the treatment of de-novo coronary small vessel disease, drug-coated balloons (DCBs) are non-inferior to drug-eluting stents (DESs) regarding clinical outcome up to 12 months, but data beyond 1 year is sparse. We aimed to test the long-term efficacy and safety of DCBs regarding clinical endpoints in an all-comer population undergoing percutaneous coronary intervention. METHODS: In this prespecified long-term follow-up of a multicentre, randomised, open-label, non-inferiority trial, patients from 14 clinical sites in Germany, Switzerland, and Austria with de-novo lesions in coronary vessels <3 mm and an indication for percutaneous coronary intervention were randomly assigned 1:1 to DCB or second-generation DES and followed over 3 years for major adverse cardiac events (ie, cardiac death, non-fatal myocardial infarction, and target-vessel revascularisation [TVR]), all-cause death, probable or definite stent thrombosis, and major bleeding (Bleeding Academic Research Consortium bleeding type 3-5). Analyses were performed on the full analysis set according to the modified intention-to-treat principle. Dual antiplatelet therapy was recommended for 1 month after DCB and 6 months after DES with stable symptoms, but 12 months with acute coronary syndromes. The study is registered with ClinicalTrials.gov, NCT01574534 and is ongoing. FINDINGS: Between April 10, 2012, and Feb 1, 2017, of 883 patients assessed, 758 (86%) patients were randomly assigned to the DCB group (n=382) or the DES group (n=376). The Kaplan-Meier estimate of the rate of major adverse cardiac events was 15% in both the DCB and DES groups (hazard ratio [HR] 0·99, 95% CI 0·68-1·45; p=0·95). The two groups were also very similar concerning the single components of adverse cardiac events: cardiac death (Kaplan-Meier estimate 5% vs 4%, HR 1·29, 95% CI 0·63-2·66; p=0·49), non-fatal myocardial infarction (both Kaplan-Meier estimate 6%, HR 0·82, 95% CI 0·45-1·51; p=0·52), and TVR (both Kaplan-Meier estimate 9%, HR 0·95, 95% CI 0·58-1·56; p=0·83). Rates of all-cause death were very similar in DCB versus DES patients (both Kaplan-Meier estimate 8%, HR 1·05, 95% CI 0·62-1·77; p=0·87). Rates of probable or definite stent thrombosis (Kaplan-Meier estimate 1% vs 2%; HR 0·33, 95% CI 0·07-1·64; p=0·18) and major bleeding (Kaplan-Meier estimate 2% vs 4%, HR 0·43, 95% CI 0·17-1·13; p=0·088) were numerically lower in DCB versus DES, however without reaching significance. INTERPRETATION: There is maintained efficacy and safety of DCB versus DES in the treatment of de-novo coronary small vessel disease up to 3 years.

Long-Term Results After Drug-Eluting Versus Bare-Metal Stent Implantation in Saphenous Vein Grafts: Randomized Controlled Trial.

Background Efficacy data on drug-eluting stents (DES) versus bare-metal stents (BMS) in saphenous vein grafts are controversial. We aimed to compare DES with BMS among patients undergoing saphenous vein grafts intervention regarding long-term outcome. Methods and Results In this multinational trial, patients were randomized to paclitaxel-eluting or BMS. The primary end point was major adverse cardiac events (cardiac death, nonfatal myocardial infarction, and target-vessel revascularization at 1 year. Secondary end points included major adverse cardiac events and its individual components at 5-year follow-up. One hundred seventy-three patients were included in the trial (89 DES versus 84 BMS). One-year major adverse cardiac event rates were lower in DES compared with BMS (2.2% versus 16.0%, hazard ratio, 0.14; 95% CI, 0.03-0.64, P=0.01), which was mainly driven by a reduction of subsequent myocardial infarctions and need for target-vessel revascularization. Five-year major adverse cardiac event rates remained lower in the DES compared with the BMS arm (35.5% versus 56.1%, hazard ratio, 0.40; 95% CI, 0.23-0.68, P<0.001). A landmark-analysis from 1 to 5 years revealed a persistent benefit of DES over BMS (hazard ratio, 0.33; 95% CI, 0.13-0.74, P=0.007) in terms of target-vessel revascularization. More patients in the BMS group underwent multiple target-vessel revascularization procedures throughout the study period compared with the DES group (DES 1.1% [n=1] versus BMS 9.5% [n=8], P=0.013). Enrollment was stopped before the target sample size of 240 patients was reached. Conclusions In this randomized controlled trial with prospective long-term follow-up of up to 5 years, DES showed a better efficacy than BMS with sustained benefits over time. DES may be the preferred strategy in this patient population. Registration URL: https://www.clini​caltr​ials.gov; Unique identifier: NCT00595647.

Clinical Outcomes of the Portico Transcatheter Aortic Valve Delivered via Alternative Access: 30-Day and 1-Year Results of the Portico ALT Study.

OBJECTIVE: The aim of this study was to report the 30-day and 1-year outcomes and performance from the Portico Alternative Access study to obtain CE approval of the alternative access delivery system. METHODS: The Portico Alternative Access study is a multicenter, prospective, non-randomized, investigational study (www.clinicaltrials.gov identifier, NCT03056573) describing 45 patients with severe symptomatic aortic valve stenosis (AS) treated with the self-expanding Portico device using subclavian/axillary access. RESULTS: Forty-five subjects (81.7 ± 5.9 years; 57.8% female; Society of Thoracic Surgeons score, 5.4 ± 4.7%) with severe, symptomatic AS had a Portico bioprosthetic aortic valve implantation attempt via axillary/subclavian access. Implantation was successful in 97.8% of subjects. At 30 days, the rate of major vascular complications at the subclavian/axillary access site was 4.4%. All-cause mortality was 2.2% at 30 days and 4.4% at 1 year. CONCLUSION: The Portico transcatheter aortic valve can be safely delivered by axillary or subclavian access with high implant success rate and low complication rates.
