Tratamiento intervencionista de la embolia aguda de pulmón: resultados de un registro multicéntrico / Catheter-directed therapy for acute pulmonary embolism: results of a multicenter national registry

Introduction and objectives Catheter-directed therapy (CDT) for acute pulmonary embolism (PE) is an emerging therapy that combines heterogeneous techniques. The aim of the study was to provide a nationwide contemporary snapshot of clinical practice and CDT-related outcomes. Methods This Investigator-initiated multicenter registry aimed to include consecutive patients with intermediate-high risk (IHR) or high-risk (HR), acute PE eligible for CDT. The primary outcome of the study was in-hospital all-cause death. Results A total of 253 patients were included, of whom 93 (36.8%) had HR-PE, and 160 (63.2%) had IHR-PE with a mean age of 62.3±15.1 years. Local thrombolysis was performed in 70.8% and aspiration thrombectomy in 51.8%, with 23.3% of patients receiving both. However, aspiration thrombectomy was favored in the HR-PE cohort (80.6% vs 35%; P<.001). Only 51 patients (20.2%) underwent CDT with specific PE devices. The success rate for CDT was 90.9% (98.1% of IHR-PE patients vs 78.5% of HR-PE patients, P<.001). In-hospital mortality was 15.5%, and was highly concentrated in the HR-PE patients (37.6%) and significantly lower in IHR-PE patients (2.5%), P<.001. Long-term (24-month) mortality was 40.2% in HR-PE patients vs 8.2% in IHR-PE patients (P<.001). Conclusions Despite the high success rate for CDT, in-hospital mortality in HR-PE is still high (37.6%) compared with very low IHR-PE mortality (2.5%) (AU)

Introducción y objetivos El emergente tratamiento por catéter (TPC) de la embolia pulmonar (EP) aguda combina técnicas heterogéneas. El objetivo del estudio es describir la práctica clínica contemporánea y los resultados relacionados con la TPC en un registro de ámbito nacional. Métodos Registro multicéntrico iniciado por investigador, destinado a incluir a pacientes con EP aguda consecutivos y en riesgo intermedio-alto (IAR) o alto riesgo (AR) elegibles para TPC. El resultado primario del estudio fue la muerte por cualquier causa en el hospital. Resultados Se incluyó en total a 253 pacientes, 93 (36,8%) con EP-AR y 160 (63,2%) con EP-IAR, de una media de edad de 62,3±15,1. Se realizó trombolisis local al 70,8% de los pacientes, trombectomía aspirativa al 51,8% y ambas al 23,3%. Sin embargo, la trombectomía por aspiración fue más frecuente en la cohorte de EP-AR (el 80,6 frente al 35%; p<0,001). Solo 51 pacientes (20,2%) se sometieron a TPC con dispositivos específicos de EP. El éxito de la TPC fue del 90,9% (el 98,1% de los casos de EP-IAR frente al 78,5% de los de EP-AR; p<0,001). La mortalidad hospitalaria fue del 15,5%, muy concentrada en los casos de EP-AR (37,6%) y significativamente menor entre los de EP-IAR (2,5%; p<0,001). La mortalidad a largo plazo (24 meses) fue del 40,2 en EP-AR frente al 8,2% en EP-IAR (p<0,001). Conclusiones A pesar del elevado éxito de la TPC, la mortalidad hospitalaria por EP-AR sigue siendo alta (37,6%) respeto a la muy baja mortalidad de la EP-IAR (2,5%) (AU)

Very long-term efficacy and safety of paclitaxel-eluting balloon after a bare-metal stent for the treatment of ST-elevation myocardial infarction: 8-year results of a randomized clinical trial (PEBSI study).

Background: Drug-eluting stents (DES) are considered the therapy of choice in ST-segment elevation myocardial infarction (STEMI); however, a low persistent rate of revascularizations and stent thrombosis exist over the time. We have previously shown that a paclitaxel (PTX)-drug-coated balloon (DCB) after a bare-metal stent (BMS) implantation (DCB-combined strategy) yields superior angiographic and clinical results compared to BMS in the short term. However, the long-term safety and efficacy of this approach remain uncertain. Methods: An 8-year clinical follow-up was conducted on patients enrolled in the randomized PEBSI-1 trial (NCT01839890). The original trial included patients who suffered a STEMI, patients were randomly assigned to receive a DCB-combined strategy or BMS only and the primary endpoint was in-stent late luminal loss (LLL) at 9-month follow-up. After the completion of this study, death, myocardial re-infarction, ischemia-driven repeated revascularizations included target lesion revascularization (TLR) and target vessel revascularization (TVR), and stent thrombosis, were assessed by yearly contact by a clinical visit, telephone or by electronic records. These outcomes were adhered to ARC-2 criteria. Results: The rate of incomplete follow-up was very low, with only 3 out of 111 patients (2.7%) in the DCB-combined strategy group and 1 out of 112 patients (0.9%) in the BMS group. At 8 years there were a lower rate of TVR [3.7% vs. 14.3%; hazard ratio (HR): 0.243; 95% confidence interval (CI): 0.081-0.727; P=0.006], and a trend towards lower TLR (2.8% vs. 8.9%; HR: 0.300; 95% CI: 0.083-1.090; P=0.052) in the DCB-combined strategy group. No statistical difference between the DCB-combined strategy and BMS groups were found for all causes of death, deaths from cardiovascular disease, reinfarctions or stent thrombosis. Notably in the DCB-combined strategy group, no episode of stent thrombosis occurred after the first year. Similarly, there were no cardiovascular deaths, TVR and TLR in the DCB-combined strategy group after 5 years. In contrast, during the period from year 5 to 8, the BMS group experienced an additional cardiovascular death, as well as one case of TVR, one case of TLR, and one case of stent thrombosis. Conclusions: In STEMI patients, the DCB-combined strategy maintains its safety and clinical efficacy over time. Our rates of TVR, TLR, and very late stent thrombosis (VLST) at very long-term are the lowest ever found in a STEMI trial. Further studies are warranted to assess the potential superiority of this novel strategy as compared with new-generation DES to prevent very late events in these patients.

Spanish cardiac catheterization and coronary intervention registry. 32nd official report of the Interventional Cardiology Association of the Spanish Society of Cardiology (1990-2022).

INTRODUCTION AND OBJECTIVES: This article presents the annual activity report of the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) for the year 2022. METHODS: All Spanish centers with catheterization laboratories were invited to participate. Data were collected online and were analyzed by an external company in collaboration with the members of the board of the ACI-SEC. RESULTS: A total of 111 centers participated. The number of diagnostic studies increased by 4.8% compared with 2021, while that of percutaneous coronary interventions (PCI) remained stable. PCIs on the left main coronary artery increased by 22%. The radial approach continued to be preferred for PCI (94.9%). There was an upsurge in the use of drug-eluting balloons, as well as in intracoronary imaging techniques, which were used in 14.7% of PCIs. The use of pressure wires also increased (6.3% vs 2021) as did plaque modification techniques. Primary PCI continued to grow and was the most frequent treatment (97%) in ST-segment elevation myocardial infarction. Most noncoronary procedures maintained their upward trend, particularly percutaneous aortic valve implantation, atrial appendage closure, mitral/tricuspid edge-to-edge therapy, renal denervation, and percutaneous treatment of pulmonary arterial disease. CONCLUSIONS: The Spanish cardiac catheterization and coronary intervention registry for 2022 reveals a rise in the complexity of coronary disease, along with a notable growth in procedures for valvular and nonvalvular structural heart disease.

Percutaneous paravalvular leak closure after transcatheter aortic valve implantation: the international PLUGinTAVI Registry.

BACKGROUND: Data regarding the safety and long-term effectiveness of percutaneous closure of paravalvular leak (PVL) after transcatheter aortic valve implantation (TAVI) are scarce. AIMS: This study aims to present a large multicentre international experience of percutaneous post-TAVI PVL closure. METHODS: All patients who underwent percutaneous post-TAVI PVL closure in 14 hospitals across Europe and North America between January 2018 and October 2022 were included. RESULTS: Overall, 45 patients (64% male) were enrolled. The median age was 80 years (75-84). Among them, 67% and 33% had self-expanding and balloon-expandable valve implantations, respectively. Baseline post-TAVI PVL was severe in 67% of cases and moderate in the rest. The time from index TAVI to PVL closure procedure was 16.1 (8.7-34.8) months. Most patients were in NYHA Class III and IV (73%) before the procedure, and 40% had referred hospitalisations for heart failure between TAVI and the PVL closure procedure. Successful PVL closure was achieved in 94%, reducing regurgitation to ≤mild in 91% and moderate in the rest. The Amplatzer Valvular Plug III was the most frequently used device (27 cases), followed by the Amplatzer Valvular Plug 4. The incidence of severe adverse events was 11%. None of the patients died during the index hospitalisation. During long-term follow-up (21.7±16.2 months), the all-cause mortality rate was 14%, and patients presented improvement in functional status and a significant reduction in the rate of hospitalisation for heart failure (from 40% to 6%). CONCLUSIONS: Percutaneous PVL closure is a feasible and safe option for treating post-TAVI leaks. Successful PVL reduction to mild or less could be associated with acute and long-lasting improvements in clinical outcomes.

Coronary Obstruction After Transcatheter Aortic Valve Replacement: Insights From the Spanish TAVI Registry.

BACKGROUND: Coronary obstruction (CO) following transcatheter aortic valve replacement (TAVR) is a life-threatening complication, scarcely studied. OBJECTIVES: The authors analyzed the incidence of CO after TAVR, presentation, management, and in-hospital and 1-year clinical outcomes in a large series of patients undergoing TAVR. METHODS: Patients from the Spanish TAVI (Transcatheter Aortic Valve Implantation) registry who presented with CO in the procedure, during hospitalization or at follow-up were included. Computed tomography (CT) risk factors were assessed. In-hospital, 30-day, and 1-year all-cause mortality rates were analyzed and compared with patients without CO using logistic regression models in the overall cohort and in a propensity score-matched cohort. RESULTS: Of 13,675 patients undergoing TAVR, 115 (0.80%) presented with a CO, mainly during the procedure (83.5%). The incidence of CO was stable throughout the study period (2009-2021), with a median annual rate of 0.8% (range 0.3%-1.3%). Preimplantation CT scans were available in 105 patients (91.3%). A combination of at least 2 CT-based risk factors was less frequent in native than in valve-in-valve patients (31.7% vs 78.3%; P < 0.01). Percutaneous coronary intervention was the treatment of choice in 100 patients (86.9%), with a technical success of 78.0%. In-hospital, 30-day, and 1-year mortality rates were higher in CO patients than in those without CO (37.4% vs 4.1%, 38.3% vs 4.3%, and 39.1% vs 9.1%, respectively; P < 0.001). CONCLUSIONS: In this large, nationwide TAVR registry, CO was a rare, but often fatal, complication that did not decrease over time. The lack of identifiable predisposing factors in a subset of patients and the frequently challenging treatment when established may partly explain these findings.

Changes in the Treatment Strategy Following Intracoronary Pressure Wire in a Contemporaneous Real-Life Cohort of Patients With Intermediate Coronary Stenosis. Results From a Nationwide Registry.

BACKGROUND: Intracoronary pressure wire is useful to guide revascularization in patients with coronary artery disease. AIMS: To evaluate changes in diagnosis (coronary artery disease extent), treatment strategy and clinical results after intracoronary pressure wire study in real-life patients with intermediate coronary artery stenosis. METHODS: Observational, prospective and multicenter registry of patients in whom pressure wire was performed. The extent of coronary artery disease and the treatment strategy based on clinical and angiographic criteria were recorded before and after intracoronary pressure wire guidance. 12-month incidence of MACE (cardiovascular death, non-fatal myocardial infarction or new revascularization of the target lesion) was assessed. RESULTS: 1414 patients with 1781 lesions were included. Complications related to the procedure were reported in 42 patients (3.0 %). The extent of coronary artery disease changed in 771 patients (54.5 %). There was a change in treatment strategy in 779 patients (55.1 %) (18.0 % if medical treatment; 68.8 % if PCI; 58.9 % if surgery (p < 0.001 for PCI vs medical treatment; p = 0.041 for PCI vs CABG; p < 0.001 for medical treatment vs CABG)). In patients with PCI as the initial strategy, the change in strategy was associated with a lower rate of MACE (4.6 % vs 8.2 %, p = 0.034). CONCLUSIONS: The use of intracoronary pressure wire was safe and led to the reclassification of the extent of coronary disease and change in the treatment strategy in more than half of the cases, especially in patients with PCI as initial treatment.

Early clinical outcomes after transaxillary versus transfemoral TAVI. Data from the Spanish TAVI registry.

INTRODUCTION AND OBJECTIVES: Transaxillary access (TXA) has become the most widely used alternative to transfemoral access (TFA) in patients undergoing transcatheter aortic valve implantation (TAVI). The aim of this study was to compare total in-hospital and 30-day mortality in patients included in the Spanish TAVI registry who were treated by TXA or TFA access. METHODS: We analyzed data from patients treated with TXA or TFA and who were included in the TAVI Spanish registry. In-hospital and 30-day events were defined according to the recommendations of the Valve Academic Research Consortium. The impact of the access route was evaluated by propensity score matching according to clinical and echocardiogram characteristics. RESULTS: A total of 6603 patients were included; 191 (2.9%) were treated via TXA and 6412 via TFA access. After adjustment (n=113 TXA group and n=3035 TFA group) device success was similar between the 2 groups (94%, TXA vs 95%, TFA; P=.95). However, compared with the TFA group, the TXA group showed a higher rate of acute myocardial infarction (OR, 5.3; 95%CI, 2.0-13.8); P=.001), renal complications (OR, 2.3; 95%CI, 1.3-4.1; P=.003), and pacemaker implantation (OR, 1.6; 95%CI, 1.01-2.6; P=.03). The TXA group also had higher in-hospital and 30-day mortality rates (OR, 2.2; 95%CI, 1.04-4.6; P=.039 and OR, 2.3; 95%CI, 1.2-4.5; P=.01, respectively). CONCLUSIONS: Compared with ATF, TXA is associated with higher total mortality, both in-hospital and at 30 days. Given these results, we believe that TXA should be considered only in those patients who are not suitable candidates for TFA.

Prognostic Role of TAPSE to PASP Ratio in Patients Undergoing MitraClip Procedure.

BACKGROUND: Transcatheter mitral valve repair (TMVR) is an effective therapy for high-risk patients with severe mitral regurgitation (MR) but heart failure (HF) readmissions and death remain substantial on mid-term follow-up. Recently, right ventricular (RV) to pulmonary arterial (PA) coupling has emerged as a relevant prognostic predictor in HF. In this study, we aimed to assess the prognostic value of tricuspid annular plane systolic excursion (TAPSE) to PA systolic pressure (PASP) ratio as a non-invasive measure of RV-to-PA coupling in patients undergoing TMVR with MitraClip (Abbott, CA, USA). METHODS: Multicentre registry including 228 consecutive patients that underwent successful TMVR with MitraClip. The sample was divided in two groups according to TAPSE/PASP median value: 0.35. The primary combined endpoint encompassed HF readmissions and all-cause mortality. RESULTS: Mean age was 72.5 ± 11.5 years and 154 (67.5%) patients were male. HF readmissions and all-cause mortality were more frequent in patients with TAPSE/PASP ≤ 0.35: Log-Rank 8.844, p = 0.003. On Cox regression, TAPSE/PASP emerged as a prognostic predictor of the primary combined endpoint, together with STS-Score. TAPSE/PASP was a better prognostic predictor than either TAPSE or PASP separately. CONCLUSIONS: TAPSE/PASP ratio appears as a novel prognostic predictor in patients undergoing MitraClip implantation that might improve risk stratification and candidate selection.

Impact of diabetes in patients waiting for invasive cardiac procedures during COVID-19 pandemic.

BACKGROUND: During COVID-19 pandemic, elective invasive cardiac procedures (ICP) have been frequently cancelled or postponed. Consequences may be more evident in patients with diabetes. OBJECTIVES: The objective was to identify the peculiarities of patients with DM among those in whom ICP were cancelled or postponed due to the COVID-19 pandemic, as well as to identify subgroups in which the influence of DM has higher impact on the clinical outcome. METHODS: We included 2,158 patients in whom an elective ICP was cancelled or postponed during COVID-19 pandemic in 37 hospitals in Spain. Among them, 700 (32.4%) were diabetics. Patients with and without diabetes were compared. RESULTS: Patients with diabetes were older and had a higher prevalence of other cardiovascular risk factors, previous cardiovascular history and co-morbidities. Diabetics had a higher mortality (3.0% vs. 1.0%; p = 0.001) and cardiovascular mortality (1.9% vs. 0.4%; p = 0.001). Differences were especially important in patients with valvular heart disease (mortality 6.9% vs 1.7% [p < 0.001] and cardiovascular mortality 4.9% vs 0.9% [p = 0.002] in patients with and without diabetes, respectively). In the multivariable analysis, diabetes remained as an independent risk factor both for overall and cardiovascular mortality. No significant interaction was found with other clinical variables. CONCLUSION: Among patients in whom an elective invasive cardiac procedure is cancelled or postponed during COVID-19 pandemic, mortality and cardiovascular mortality is higher in patients with diabetes, irrespectively on other clinical conditions. These procedures should not be cancelled in patients with diabetes.

Percutaneous Mitral Valve Repair: Outcome Improvement with Operator Experience and a Second-Generation Device.

BACKGROUND AND AIM: Recent randomized data comparing percutaneous mitral valve repair (PMVR) versus optimal medical treatment in patients with functional MR (FMR) seemed to highlight the importance of the learning curve not only for procedural outcomes but also for patient selection. The aim of the study was to compare a contemporary series of patients undergoing PMVR using a second-generation Mitraclip device (Mitraclip NT) with previous cohorts treated with a first-generation system. METHODS: This multicenter study collected individual data from 18 centers between 2012 and 2017. The cohort was divided into three groups according to the use of the first-generation Mitraclip during the first (control-1) or second half (control-2) or the Mitraclip NT system. RESULTS: A total of 545 consecutive patients were included in the study. Among all, 182 (33.3%), 183 (33.3%), and 180 (33.3%) patients underwent mitral repair in the control-1, control-2, and NT cohorts, respectively. Procedural success was achieved in 93.3% of patients without differences between groups. Major adverse events did not statistically differ among groups, but there was a higher rate of pericardial effusion in the control-1 group (4.3%, 0.6%, and 2.6%, respectively; p = 0.025). The composite endpoint of death, surgery, and admission for congestive heart failure (CHF) at 12 months was lower in the NT group (23.5% in control-1, 22.5% in control-2, and 8.3% in the NT group; p = 0.032). CONCLUSIONS: The present paper shows that contemporary clinical outcomes of patients undergoing PMVR with the Mitraclip system have improved over time.

Consequences of canceling elective invasive cardiac procedures during Covid-19 outbreak.

BACKGROUND: During COVID-19 pandemic in Spain, elective procedures were canceled or postponed, mainly due to health care systems overwhelming. OBJECTIVE: The objective of this study was to evaluate the consequences of interrupting invasive procedures in patients with chronic cardiac diseases due to the COVID-19 outbreak in Spain. METHODS: The study population is comprised of 2,158 patients that were pending on elective cardiac invasive procedures in 37 hospitals in Spain on the 14th of March 2020, when a state of alarm and subsequent lockdown was declared in Spain due to the COVID-19 pandemic. These patients were followed-up until April 31th. RESULTS: Out of the 2,158 patients, 36 (1.7%) died. Mortality was significantly higher in patients pending on structural procedures (4.5% vs. 0.8%, respectively; p < .001), in those >80 year-old (5.1% vs. 0.7%, p < .001), and in presence of diabetes (2.7% vs. 0.9%, p = .001), hypertension (2.0% vs. 0.6%, p = .014), hypercholesterolemia (2.0% vs. 0.9%, p = .026) [Correction added on December 23, 2020, after first online publication: as per Dr. Moreno's request changes in p-values were made after original publication in Abstract.], chronic renal failure (6.0% vs. 1.2%, p < .001), NYHA > II (3.8% vs. 1.2%, p = .001), and CCS > II (4.2% vs. 1.4%, p = .013), whereas was it was significantly lower in smokers (0.5% vs. 1.9%, p = .013). Multivariable analysis identified age > 80, diabetes, renal failure and CCS > II as independent predictors for mortality. CONCLUSION: Mortality at 45 days during COVID-19 outbreak in patients with chronic cardiovascular diseases included in a waiting list due to cancellation of invasive elective procedures was 1.7%. Some clinical characteristics may be of help in patient selection for being promptly treated when similar situations happen in the future.

Transcatheter Mitral Repair for Functional Mitral Regurgitation According to Left Ventricular Function: A Real-Life Propensity-Score Matched Study.

BACKGROUND: Transcatheter mitral valve repair (TMVR) could improve survival in functional mitral regurgitation (FMR), but it is necessary to consider the influence of left ventricular ejection fraction (LVEF). Therefore, we compare the outcomes after TMVR with Mitraclip® between two groups according to LVEF. METHODS: In an observational registry study, we compared the outcomes in patients with FMR who underwent TMVR with and without LVEF <30%. The primary endpoint was the combined one-year all-cause mortality and unplanned hospital readmissions due to HF. The secondary end-points were New York Heart Association (NYHA) functional class and mitral regurgitation (MR) severity. Propensity-score matching was used to create two groups with the same baseline characteristics, except for baseline LVEF. RESULTS: Among 535 FMR eligible patients, 144 patients with LVEF <30% (group 1) and 144 with LVEF >30% (group 2) had similar propensity scores and were included in the analyses. The primary study endpoint was significantlly higher in group 1 (33.3% vs. 9.4%, p = 0.002). There was a maintained improvement in secondary endpoints without significant differences among groups. CONCLUSION: FMR patients with LVEF <30% treated with MitraClip® had higher mortality and readmissions than patients with LVEF ≥30% treated with the same device. However, both groups improved the NYHA functional class and MR severity.

Acute Coronary Syndromes, Gastrointestinal Protection, and Recommendations Regarding Concomitant Administration of Proton-Pump Inhibitors (Omeprazol/Esomeprazole) and Clopidogrel.

The Food and Drug Administration and the European Medicines Agency sent a warning in 2010 discouraging the concomitant use of clopidogrel with omeprazole or esomeprazole. The purpose is to know the gastroprotective approach in patients with acute coronary syndrome (ACS) and the level of follow-up of the alert. In 17 hospitals with catheterization laboratory in Spain, 1 per region, we studied 25 consecutive patients per hospital whose diagnosis of discharge since October 1, 2013, had been any type of ACS. We analyzed their baseline clinical profile, the gatroprotective agents at admission and discharge and the antiplatelet therapy at discharge. The number of patients included was 425: age 67.2 ± 12.5 years, women 29.8%, diabetes 36.5%. The patients presented unstable angina in 21.6%, non-ST-elevation myocardial infarction in 35.3% and ST-elevation myocardial infarction in 43.1%. Conservative approach was chosen in 17.9%, bare-metal stents 32.2%, ≥ 1 drug-eluting stent 48.5%, and surgery 1.4%. Aspirin was indicated in 1.9%, aspirin + clopidogrel 73.6%, aspirin + prasugrel 17.6%, and aspririn + ticagrelor 6.8%. Gastroprotective agents were present in 40.2% patients at admission and this percentage increased to 93.7% at discharge. Of the 313 (73.6%) on clopidogrel in 96 (30.6%) was combined with omeprazole and 3 (0.95%) with esomeprazole, whereas the most commonly used was pantoprazole with 190 patients (44.7%). In conclusion, almost the totality of the patients with an ACS receive gastroprotective agents at the moment of discharge, most of them with proton-pump inhibitors. In one every 3 cases of the patients who are on clopidogrel, the recommendation of the Food and Drug Administration and the European Medicines Agency is not followed.

Immediate and Long-Term Results of Drug-Eluting Stents in Mammary Artery Grafts.

UNLABELLED: Percutaneous intervention of a coronary graft is the treatment of choice when the graft fails. The objective is to report the long-term results of drug-eluting stents (DES) in mammary artery grafts (MAG). Patients who had been treated with DES for MAG in 27 centers were selected. The baseline and procedural clinical data were included prospectively, and the follow-up was performed with the patients, families, and medical records. Two hundred and sixty-eight patients were included: age 65.5 ± 10.1 years, diabetes 47.8%, ejection fraction 55.5 ± 14.9%. INDICATION: stable angina 28.4%, unstable angina 38.1%, non-ST-elevation myocardial infarction 21.6%, ST-elevation myocardial infarction 5.3%, and heart failure 6.7%; 1.19 ± 0.59 stents/patient were implanted measuring 18.8 ± 8.8 mm in length and 2.68 ± 0.35 mm in diameter. Rapamycin was used in 78 cases (29.1%), paclitaxel in 77 (28.7%), everolimus in 70 (26.1%), zotarolimus in 34 (12.7%), and biolimus in 9 (3.4%). All cases were successful except for 1 in which the patient died 30 minutes after the procedure. There were no other inhospital events. After a follow-up of 41 months (Q25: 23.7 to Q75: 57.8), 24 patients (9%) died of heart-related causes and 20 (7.5%) of noncardiac causes. Repeat revascularization was necessary in 31 cases, and in 1 additional patient, there was total occlusion, which was not treated. These 32 patients represented 11.9% of the total. In conclusion, the implantation of DES in MAG shows very high procedural success and also low long-term event rates.
