RESUMEN

BACKGROUND: Patients with inflammatory bowel disease (IBD) are at increased risk after percutaneous coronary intervention (PCI). OBJECTIVES: To compare the clinical outcomes within 30 days, one year, and five years of undergoing PCI. METHODS: We conducted a retrospective cohort study of adult patients with IBD who underwent PCI in a tertiary care center from January 2009 to December 2019. RESULTS: We included 44 patients, 26 with Crohn's disease (CD) and 18 with ulcerative colitis (UC), who underwent PCI. Patients with CD underwent PCI at a younger age compared to UC (57.8 vs. 68.9 years, P < 0.001) and were more likely to be male (88.46% of CD vs. 61.1% of UC, P < 0.03). CD patients had a higher rate of non-steroidal treatment compared to UC patients (50% vs. 5.56%, P < 0.001). Acute coronary syndromes (ACS) and/or the need for revascularization (e.g., PCI) were the most common clinical events to occur following PCI, in both groups. Of patients who experienced ACS and/or unplanned revascularization within 5 years, 25% of UC vs. 40% of CD had target lesion failure (TLF) due to in-stent restenosis and 10% of CD had TLF due to stent thrombosis. CONCLUSIONS: We observed higher rates of TLF in IBD patients compared to the general population as well as differences in clinical outcomes between UC and CD patients. A better understanding of the prognostic factors and pathophysiology of these differences may have clinical importance in tailoring the appropriate treatment or type of revascularization for this high-risk group.

RESUMEN

BACKGROUND: Patients treated with percutaneous coronary intervention are often considered to be at a high bleeding risk (HBR). Drug-eluting stents have been shown to be superior to bare-metal stents in patients with HBR, even when patients were given abbreviated periods of dual antiplatelet therapy (DAPT). Short DAPT has not been evaluated with the EluNIR ridaforolimus-eluting stent. The aim of this study was to evaluate the safety and efficacy of a shortened period of DAPT following implantation of the ridaforolimus-eluting stent in patients with HBR. METHODS AND RESULTS: This was a prospective, multicenter, binational, single-arm, open-label trial. Patients were defined as HBR according to the LEADERS-FREE (Prospective Randomized Comparison of the BioFreedom Biolimus A9 Drug-Coated Stent versus the Gazelle Bare-Metal Stent in Patients at High Bleeding Risk) trial criteria. After percutaneous coronary intervention, DAPT was given for 1 month to patients presenting with stable angina. In patients presenting with an acute coronary syndrome, DAPT was given for 1 to 3 months, at the investigator's discretion. The primary end point was a composite of cardiac death, myocardial infarction, or stent thrombosis up to 1 year (Academic Research Consortium definite and probable). Three hundred fifteen patients undergoing percutaneous coronary intervention were enrolled, and 56.4% presented with acute coronary syndrome; 33.7% were receiving oral anticoagulation. At 1 year, the primary end point occurred in 15 patients (4.9%), meeting the prespecified performance goal of 14.1% (P<0.0001). Stent thrombosis (Academic Research Consortium definite and probable) occurred in 2 patients (0.6%). Bleeding Academic Research Consortium type 3 and 5 bleeding occurred in 6 patients (1.9%). CONCLUSIONS: We observed favorable results in patients with HBR who underwent percutaneous coronary intervention with a ridaforolimus-eluting stent and received shortened DAPT, including a low rate of ischemic events and low rate of stent thrombosis.

RESUMEN

INTRODUCTION: The ridaforolimus-eluting stent (RES) system uses a novel cobalt alloy-based coronary stent with a durable elastomeric polymer eluting ridaforolimus. AIM OF STUDY: To assess the safety and efficacy of small diameter (2.25 mm) RES (EluNIR) in small coronary artery disease. METHODS: A prospective, multicenter, single-arm, open-label clinical trial. Clinical follow-up was performed at 30 days, 6 months, and 1 year after the procedure. Target lesions were located in native coronary arteries or bypass graft conduits, with visually estimated diameter of ≥2.25 mm to ≤2.5 mm. The primary endpoint was combined device success, defined as final in-stent residual diameter stenosis <30%, without 30-day major adverse cardiovascular events (MACE). RESULTS: A total of 81 patients were enrolled in the study. Twenty-three patients (28%) had acute coronary syndrome (ACS) at presentation and 37 (46%) had prior myocardial infarction (MI). Most of the target lesions were located in the circumflex coronary artery (44%) and were classified as B2/C grade according to the American Heart Association/American College of Cardiology classification. The final mean minimal lumen diameter, mean reference vessel diameter, and mean residual percent diameter stenosis were 2.0 ± 0.2 mm, 2.3 ± 0.1 mm, and 14 + 6.6%, respectively. The primary endpoint of device success without 30-day MACE was achieved in 98.8% of the patients. Target lesion failure (TLF) at 6 months was 1.2%. Thirty-day and 1-year MACE rates were 1.2% and 2.5%, respectively. CONCLUSION: The EluNIR 2.25 mm stent shows excellent results in small coronary artery disease and adds another tool in the treatment of this complex lesion type.

RESUMEN

OBJECTIVES: This study examines relationships between door to balloon (D2B) time and subsequent admissions due to heart failure (HF), acute coronary syndrome (ACS), and mortality for up to 1 year. BACKGROUND: Current guidelines set 90-min for D2B time for primary percutaneous coronary intervention (PPCI) as a goal, which has been shown to reduce mortality and adverse events. METHODS: Using the MDclone ADAMS system integrated with our electronic medical records, we conducted retrospective analysis of all patients admitted due to ST-elevation myocardial infarction from home, without any history of HF or coronary disease, and who underwent PPCI during 2013-2019. Data on D2B time, baseline clinical and demographic characteristics, and outcomes of HF, ACS and mortality were collected. Adjusted HR for each of the outcomes was calculated by multivariate Cox model. RESULTS: A total of 826 patients were included in the final analysis. D2B had no significant effect on incidence of heart failure admissions for up to 1-year follow-up. D2B had a significant effect on mortality at 180 days, showing a 30% increase for each 30-min increase (HR 1.308; CI, 1.046-1.635) as for ACS at 90 days (HR 1.307; 1.025-1.638). The 30-min D2B cutoff showed a significant increase in ACS recurrence throughout the follow-up period at 90 days (HR 2.871, 1.239-6.648), 180 days (HR 2.607, 1.255-5.413), and 1 year (HR 1.886, 1.073-3.317). CONCLUSIONS: Patients with shorter D2B times had significantly reduced mortality and recurrence of ACS, with no effect on heart failure admission incidence.

RESUMEN

BACKGROUND: Gout is a common chronic inflammatory disease with increasing prevalence over the last decades. However, there is limited evidence on outcomes of PCI in patients with gout. METHODS: A Retrospective cohort study of all adult patients who underwent PCI in a large [1000 bed] tertiary care center from January 2002 to August 2020. Patients were stratified according to a diagnosis of gout. The primary outcome was defined as the first event of all-cause mortality or major CV event that included acute coronary syndrome -(ACS) or congestive heart failure -(CHF) related admission. To examine the association between gout and outcome, a multi-variable cox proportional hazard model was used. RESULTS: Out of 12,951 who patients underwent PCI during the study period, 344 (2.7%) had a diagnosis of gout. The study median follow-up time was 105 months. Patients with gout had significantly higher crude rates of clinical events (73.8% vs. 59.5%, p < 0.001). Gout was associated with increased risk for ACS and HF-admissions [HR 1.24 95%CI (1.07-1.43), p = 0.04; HR 1.99, 95%CI (1.57-2.54) p < 0.001, respectively], as well as for any clinical event (HR 1.2 95%CI (1.04-1.38), P = 0.01). CONCLUSION: Gout is associated with increased post-PCI cardiovascular risk. Therefore, patients with gout should be considered as a higher risk cohort.

RESUMEN

Reliable femoral artery closure devices are essential for the success of trans-femoral Transcatheter Aortic Valve Implantation (TAVI) procedures. Accordingly, device choice might affect vascular complications and bleeding rates. This was a retrospective analysis, comparing vascular complication rates among patients who underwent trans-femoral TAVI with vascular access closure using either the ProGlide parallel suture or Prostar closure devices. We included 191 patients: 106 were treated with Prostar and 85 with ProGlide. The ProGlide group had higher rate of diabetes, chronic kidney disease, peripheral arterial disease, and significantly smaller femoral arteries that were treated via larger sheaths. Valve Academic Research Consortium (VARC)-2 major complications were similar between the groups. (4.7% for ProGlide vs 3.8% for Prostar, P=1), with similar incidence of closure device failure (2 vs 3, P=1). No differences were found after univariant analysis and propensity-score matching in the incidence of major and minor bleeding nor in the rate of in-hospital mortality between ProGlide and Prostar (4.7 vs 2.8%, P=.7, 1.2 vs 2.8%, P=.63, and 1.2 vs .0%, P=.45, respectively). Parallel suture technique using two ProGlide sutures showed comparable rates of vascular complications to the Prostar closure device in higher risk population of TAVI patients.

RESUMEN

AIMS: Severe mitral regurgitation (MR) following acute myocardial infarction (MI) is associated with high mortality rates and has inconclusive recommendations in clinical guidelines. We aimed to report the international experience of patients with secondary MR following acute MI and compare the outcomes of those treated conservatively, surgically, and percutaneously. METHODS AND RESULTS: Retrospective international registry of consecutive patients with at least moderate-to-severe MR following MI treated in 21 centres in North America, Europe, and the Middle East. The registry included patients treated conservatively and those having surgical mitral valve repair or replacement (SMVR) or percutaneous mitral valve repair (PMVR) using edge-to-edge repair. The primary endpoint was in-hospital mortality. A total of 471 patients were included (43% female, age 73 ± 11 years): 205 underwent interventions, of whom 106 were SMVR and 99 PMVR. Patients who underwent mitral valve intervention were in a worse clinical state (Killip class ≥3 in 60% vs. 43%, P < 0.01), but yet had lower in-hospital and 1-year mortality compared with those treated conservatively [11% vs. 27%, P < 0.01 and 16% vs. 35%, P < 0.01; adjusted hazard ratio (HR) 0.28, 95% confidence interval (CI) 0.18-0.46, P < 0.01]. Surgical mitral valve repair or replacement was performed earlier than PMVR [median of 12 days from MI date (interquartile range 5-19) vs. 19 days (10-40), P < 0.01]. The immediate procedural success did not differ between SMVR and PMVR (92% vs. 93%, P = 0.53). However, in-hospital and 1-year mortality rates were significantly higher in SMVR than in PMVR (16% vs. 6%, P = 0.03 and 31% vs. 17%, P = 0.04; adjusted HR 3.75, 95% CI 1.55-9.07, P < 0.01). CONCLUSIONS: Early intervention may mitigate the poor prognosis associated with conservative therapy in patients with post-MI MR. Percutaneous mitral valve repair can serve as an alternative for surgery in reducing MR for high-risk patients.

RESUMEN

Background Multiple contrast media exposures are common, but their cumulative effect on renal function is unknown. We aimed to investigate the renal consequences of repeated exposures to contrast media with coronary interventions. Methods and Results We studied 2942 patients who underwent between 1 and 9 procedures. The primary end point was a persistent creatinine increase of ≥50% above baseline at ≥90 days after the last procedure. The effect of cumulative contrast media dose was assessed using Cox models, with cumulative exposure as a time-dependent variable, and propensity score matching. The primary end point occurred in 190 patients (6.5%), with 6.1%, 6.8%, and 6.2% of patients with 1, 2 or 3, and ≥4 procedures, respectively (P=0.75). In the multivariable Cox model, baseline renal function, diabetes, anemia, acute coronary syndrome, and heart failure were independent predictors of the primary end point (all P≤0.01), whereas cumulative contrast dose was not (hazard ratio [HR], 1.29 [95% CI, 0.89-1.88] for the fourth contrast quartile [>509 mL] versus first contrast quartile [<233 mL]). Propensity score matching yielded 384 patient pairs with similar characteristics and either 1 or 2 to 9 contrast exposures (median cumulative dose, 160 and 480 mL, respectively). Despite large differences in the cumulative contrast exposure, there were similar rates of the primary end points (7.3% versus 6.3%, respectively; HR, 0.76 [95% CI, 0.44-1.32]). Conclusions In patients with multiple exposures to contrast media, worsening of renal function over time is associated with known risk factors for the progression of kidney disease but not with cumulative contrast volume.

RESUMEN

There is a growing interest in transcutaneous aortic valve implantation (TAVI) therapy among patients with bicuspid severe aortic stenosis (BAV). Conduction disturbances remain a frequent complication of TAVI, and new-onset permanent LBBB (NOP-LBBB) post-TAVI may be a marker of worse outcomes. We aimed to evaluate the rate of NOP-LBBB following TAVI among patients with BAV as compared to tricuspid severe aortic stenosis (TAV). Patients enrolled in the multicenter (5 centers) Bicuspid AS TAVI Registry were reviewed and compared with patients with TAV. Patients with previous aortic valve replacement, other valve morphologies and those with preprocedural LBBB or pacemaker were excluded. NOP-LBBB was defined as LBBB first detected and persisting 30-days following TAVI. A total of 387 patients (66 with BAV, 321 with TAV), age 80.3 ± 7.3, 47% females were analyzed. The device success rates were 95% in both groups without any conversions to surgery. The rate of NOP-LBBB was significantly higher among patients with BAV versus TAV (29.2% vs 16.9%, p = 0.02). However, the rate of post procedural pacemaker implantation was similar (14.8% vs 12.5%; respectively, p = 0.62). In BAV and TAV groups, 1-year mortality (6.1% vs 7.2%; respectively, p = 0.75) and stroke rates (6.1% vs 3.5%; respectively, p = 0.30) were not significantly different. Multivariate analysis identified BAV as an independent predictor of NOP-LBBB (AdjOR = 2.7, 95%CI 1.3 to 5.4). Furthermore, BAV subtypes with raphe (type 1) were identified as independent predictors of NOP-LBBB (AdjOR = 3.2, 95%CI: 1.5 to 6.7). In conclusion, patients with BAV undergoing TAVI have greater risk for developing NOP-LBBB compared with patients with TAV and the presence of raphe was associated with increased risk of NOP-LBBB. The prognostic significance for this finding warrants further evaluation in future studies.

RESUMEN

OBJECTIVE: To assess the long-term outcomes of patients with chronic inflammatory diseases who underwent percutaneous coronary intervention (PCI). METHODS: A Retrospective cohort study of all adult patients who underwent PCI in a large tertiary care center from January 2002 to August 2020. RESULTS: A total of 12,951 patients underwent PCI during the study period and were included in the cohort. The population of chronic inflammatory diseases includes 247 (1.9%) patients; 70 with inflammatory bowel disease (IBD) and 173 with autoimmune rheumatic diseases (AIRD). The composite endpoint of mortality, acute coronary syndrome (ACS) or admission due to acute heart failure was similar at 30 days and more frequent in the inflammatory disease group (42.8% in AIRD group, 35.7% in the IBD group and 29.6% in the noninflammatory group, p < 0.0001). The adjusted cox regression model found a statistically significant increased risk of the composite primary endpoints of around 40% for patients both with AIRD and IBD. Readmission due to ACS was also increases at 30 days in the AIRD group compared to the noninflammatory group (0.6% vs. 0.1%, p < 0.001) and 1 year (37.6% for the AIRD group, 34.3% in the IBD group and 25.5% in the noninflammatory group (p < 0.0001). Patients with inflammatory diseases were found to have a significantly increased risk congestive heart failure admissions at 1 year in a subgroup analysis of patients with myocardial infarction. CONCLUSION: Patients with AIRD and IBD are at higher risk for cardiovascular events in long-term follow up once diagnosed with CAD and treated with PCI.

RESUMEN

Q fever infective endocarditis frequently mimics degenerative valvular disease. We tested for Coxiella burnettii antibodies in 155 patients in Israel who underwent transcatheter aortic valve implantation. Q fever infective endocarditis was diagnosed and treated in 4 (2.6%) patients; follow-up at a median 12 months after valve implantation indicated preserved prosthetic valvular function.

RESUMEN

Patients with severe mitral regurgitation (MR) after myocardial infarction (MI) have an increased risk of mortality. Transcatheter mitral valve repair may therefore be a suitable therapy. However, data on clinical outcomes of patients in an acute setting are scarce, especially those with reduced left ventricle (LV) dysfunction. We conducted a multinational, collaborative data analysis from 21 centers for patients who were, within 90 days of acute MI, treated with MitraClip due to severe MR. The cohort was divided according to median left ventricle ejection fraction (LVEF)-35%. Included in the study were 105 patients. The mean age was 71 ± 10 years. Patients in the LVEF < 35% group were younger but with comparable Euroscore II, multivessel coronary artery disease, prior MI and coronary artery bypass graft surgery. Procedure time was comparable and acute success rate was high in both groups (94% vs. 90%, p = 0.728). MR grade was significantly reduced in both groups along with an immediate reduction in left atrial V-wave, pulmonary artery pressure and improvement in New York Heart Association (NYHA) class. In-hospital and 1-year mortality rates were not significantly different between the two groups (11% vs. 7%, p = 0.51 and 19% vs. 12%, p = 0.49) and neither was the 3-month re-hospitalization rate. In conclusion, MitraClip intervention in patients with acute severe functional mitral regurgitation (FMR) due to a recent MI in an acute setting is safe and feasible. Even patients with severe LV dysfunction may benefit from transcatheter mitral valve intervention and should not be excluded.

RESUMEN

OBJECTIVES: To assess outcomes in patients with acute mitral regurgitation (MR) following acute myocardial infarction (AMI) who received percutaneous mitral valve repair (PMVR) with the MitraClip device and to compare outcomes of patients who developed cardiogenic shock (CS) to those who did not (non-CS). BACKGROUND: Acute MR after AMI may lead to CS and is associated with high mortality. METHODS: This registry analyzed patients with MR after AMI who were treated with MitraClip at 18 centers within eight countries between January 2016 and February 2020. Patients were stratified into CS and non-CS groups. Primary outcomes were mortality and rehospitalization due to heart failure. Secondary outcomes were acute procedural success, functional improvement, and MR reduction. Multivariable Cox regression analysis evaluated association of CS with clinical outcomes. RESULTS: Among 93 patients analyzed (age 70.3 ± 10.2 years), 50 patients (53.8%) experienced CS before PMVR. Mortality at 30 days (10% CS vs. 2.3% non-CS; p = .212) did not differ between groups. After median follow-up of 7 months (IQR 2.5-17 months), the combined event mortality/re-hospitalization was similar (28% CS vs. 25.6% non-CS; p = .793). Likewise, immediate procedural success (90% CS vs. 93% non-CS; p = .793) and need for reintervention (CS 6% vs. non-CS 2.3%, p = .621) or re-admission due to HF (CS 13% vs. NCS 23%, p = .253) at 3 months did not differ. CS was not independently associated with the combined end-point (hazard ratio 1.1; 95% CI, 0.3-4.6; p = .889). CONCLUSIONS: Patients found to have significant MR during their index hospitalization for AMI had similar clinical outcomes with PMVR whether they presented in or out of cardiogenic shock, provided initial hemodynamic stabilization was first achieved before PMVR.

RESUMEN

BACKGROUND: Distinct anatomical features predispose bicuspid AS patients to conduction disturbances after TAVR. This study sought to evaluate whether the incidence of permanent pacemaker implantation (PPMI) and left bundle branch block (LBBB) in patients with bicuspid aortic stenosis (AS) following transcatheter aortic valve replacement (TAVR) is related to an anatomical association between bicuspid AS and short membranous septal (MS) length. METHODS: Sixty-seven consecutive patients with bicuspid AS from a Bicuspid AS TAVR multicenter registry and 67 propensity-matched patients with tricuspid AS underwent computed tomography before TAVR. RESULTS: MS length was significantly shorter in bicuspid AS compared with tricuspid AS (6.2 ± 2.5 mm vs. 8.4 ± 2.7 mm, respectively; p < 0.001). In patients with bicuspid AS, MS length and aortic valve calcification were the most powerful pre-procedural independent predictors of PPMI or LBBB (odds ratio [OR]: 1.38, 95% confidence interval [CI]: 1.15 to 1.55, p = 0.003 and OR: 1.92, 95% CI: 1.1 to 3.34, p = 0.022, respectively). When taking into account pre- and post-procedural parameters, aortic valve calcification and the difference between MS length and implantation depth were the most powerful independent predictors of PPMI or LBBB in patients with bicuspid AS (OR: 1.82, 95%: 1.1 to 3.1, p = 0.027; OR: 1.25, 95% CI: 1.10 to 1.38, p = 0.003). CONCLUSION: MS length, which was significantly shorter in bicuspid AS compared with tricuspid AS, aortic valve calcification, and device implantation deeper than MS length predict PPMI or LBBB in bicuspid AS after TAVR.

RESUMEN

Coronary artery perforation is a rare complication of percutaneous coronary intervention (PCI); its rate is estimated at 0.4- 0.7% of all PCIs. Fast recognition and response are imperative for the treatment of this potentially life-threatening complication. Available techniques for the treatment of perforations have moderate success rates and often necessitate dedicated equipment and expertise. In the case report presented, we describe a novel technique used to treat coronary perforations with readily available equipment.

RESUMEN

OBJECTIVES: To assess the impact of different types of anemia and of concomitant non-cardiovascular chronic illnesses on outcomes of patients with ST-segment elevation myocardial infarction (STEMI) and baseline anemia admitted to the Intensive Cardiac Care Unit. METHODS: Based on the mean corpuscular volume, anemia was stratified into: microcytic (<80 fL), normocytic (≥80, <96 fL), and macrocytic (≥96 fL). Data on concomitant chronic non-cardiovascular illnesses including malignancies were carefully collected. Endpoints included in-hospital bleeding as well as all-cause mortality at long-term follow-up. RESULTS: Of 1,390 patients with STEMI, 294 patients had baseline anemia (21.2%), in whom normocytic, microcytic, and macrocytic anemia was present in 77.2%, 17.0%, and 5.8% patients, respectively. In-hospital bleeding occurred in 25 (8.5%) of the study population without significant differences between the three groups. At a mean follow-up of 5.5±3.5 years, 104 patients (35.4%) had died. Mortality was the highest in patients with macrocytic anemia, followed by patients with normocytic anemia and microcytic anemia (58.8%, 37.0%, and 20.0%, respectively; P=0.009). Chronic non-cardiovascular condition was identified as an independent predictor of both in-hospital bleeding (odds ratio=2.57, P=0.01) and long-term mortality (hazard ratio [HR] 1.54, P=0.019). Performance of coronary angiography within index hospitalization was associated with lower long-term mortality (HR 0.38, P=0.001). Mean corpuscular volume did not predict either in-hospital bleeding or mortality. CONCLUSIONS: Chronic non-cardiovascular illnesses are highly prevalent among patients with STEMI and baseline anemia, and are strongly associated with higher in-hospital bleeding and long-term mortality. Type of anemia is not related to prognosis post-STEMI.

RESUMEN

Transcatheter therapies to treat tricuspid regurgitation are being developed, but few have attempted the gold standard of surgical repair: ring annuloplasty. We describe the first-ever fully percutaneous implantation of a circumferential, semirigid annuloplasty ring to treat massive secondary tricuspid regurgitation. (Level of Difficulty: Advanced.).
