ABSTRACT
OBJECTIVES: To describe the incidence, predictors, and clinical impact of permanent pacemaker insertion (PPI) following transcatheter aortic valve replacement (TAVR) in women. BACKGROUND: Data on pacemaker insertion complicating TAVR in women are scarce. METHODS: The Women's International Transcatheter Aortic Valve implantation (WIN-TAVI) is a prospective registry evaluating the safety and efficacy of TAVR in women. We included patients without preprocedural pacemakers and divided them into two groups: (1) PPI and (2) no-PPI. We identified PPI predictors using logistic regression and studied its clinical impact on the Valve Academic Research Consortium (VARC)-2 efficacy and safety endpoints. RESULTS: Out of 1019 patients, 922 were included in the analysis. Post-TAVR PPI occurred in 132 (14.3%) patients. Clinical and procedural characteristics were similar in both groups. Pre-existing right bundle branch block (RBBB) was associated with a high risk of post-TAVR PPI (OR 3.62, 95% CI 1.85-7.06, p < 0.001), while implantation of balloon-expandable prosthesis was associated with a lower risk (OR 0.47, 95% CI 0.30-0.74, p < 0.001). Post-TAVR PPI prolonged in-hospital stay by a median of 2 days (11 [9-16] days in PPI vs. 9 [7-14] days in no-PPI, p = 0.005), yet risks of VARC-2 efficacy and safety endpoints at 1 year were similar in both groups (adj HR 0.95, 95% CI 0.60-1.52, p = 0.84 and adj HR 1.22, 95% CI 0.83-1.79, p = 0.31, respectively). CONCLUSION: Pacemaker implantation following TAVR is frequent among women and is associated with pre-existing RBBB and valve type. PPI prolongs hospital stay, albeit without any significant impact on 1-year outcomes.

OBJECTIVE: To evaluate the incidence, predictors and outcomes of female patients with patient-prosthesis mismatch (PPM) following transcatheter aortic valve intervention (TAVI) for severe aortic stenosis (AS). BACKGROUND: Female AS TAVI recipients have a significantly lower mortality than surgical aortic valve replacement (SAVR) recipients, which could be attributed to the potentially lower PPM rates. TAVI has been associated with lower rates of PPM compared to SAVR. PPM in females post TAVI has not been investigated to date. METHODS: The WIN-TAVI (Women's INternational Transcatheter Aortic Valve Implantation) registry is a multicenter registry of women undergoing TAVR for severe symptomatic AS. Two hundred and fifty patients with detailed periprocedural and follow-up echocardiographic investigations were included in the WIN-TAVI echocardiographic sub-study. PPM was defined as per European guidelines stratified by the presence of obesity. RESULTS: The incidence of PPM in our population was 32.8%. Patients with PPM had significantly higher BMI (27.4 ± 6.1 vs. 25.2 ± 5.0, p = .002), smaller sized valves implanted (percentage of TAVI ≤23 mm 61% vs. 29.2%, PPM vs. no PPM, p < .001) and were more often treated with balloon expandable valves (48.3 vs. 32.5%, p < .001) rather than self expanding ones (26.3 vs. 52.8%, <.001). BMI (OR = 1.08; 95%CI 1.02-1.14, p = .011) and valve size ≤23 mm (OR = 3.00 95%CI 1.14-7.94, p = .027) were the only independent predictors of PPM. There was no significant interaction between valve size and valve type (p = .203). No significant differences were observed in 1-year mortality or major adverse cardiovascular events. CONCLUSIONS: PPM in females undergoing TAVI occurs in one third of patients. BMI and valve size ≤23 mm are independent predictors. Larger registries are required to determine the impact of PPM on future clinical outcomes.

OBJECTIVES: To assess the impact of anemia on clinical outcomes in female patients enrolled in the Women's InterNational transcatheter aortic valve implantation (WIN-TAVI) registry. BACKGROUND: Anemia is highly prevalent among females who constitute half of TAVI candidates, yet, its clinical significance remains poorly investigated. METHODS: Patients were divided into three groups according to preprocedural hemoglobin (Hb) level: (1) no anemia (Hb ≥12 g/dl), (2) mild-to-moderate anemia (10 ≤ Hb <12 g/dl), and (3) severe anemia (Hb <10 g/dl). The primary outcome was the occurrence of Valve Academic Research Consortium (VARC)-2 efficacy endpoint, a composite of mortality, stroke, myocardial infarction (MI), hospitalization for valve-related symptoms or heart failure or valve-related dysfunction at 1-year follow-up. RESULTS: Hemoglobin level was available in 877 (86.1%) patients: 412 (47.0%) had no anemia, 363 (41.4%) had mild-to-moderate anemia, and 102 (11.6%) had severe anemia. The latter group had a higher prevalence of cardiovascular risk factors. Compared with patients without anemia, severe anemia was associated with a greater risk of VARC-2 efficacy endpoint (adj HR 1.71, 95% CI: 1.02-2.87, p = .04), all-cause death (adj HR 2.36, 95% CI: 1.31-4.26, p = .004) and a composite of death, MI or stroke (adj HR 1.88, 95% CI: 1.10-3.22, p = .02) at 1 year. Moreover, an increased risk of late mortality (adj HR 1.15, 95% CI: 1.02-1.30, p = .03) was observed with every 1 g/dl decrease in hemoglobin level. CONCLUSION: Severe anemia in females undergoing TAVI was independently associated with increased rates of VARC-2 efficacy endpoint and mortality at 1 year.

AIMS: Due to bioprosthetic valve degeneration, aortic valve-in-valve (ViV) procedures are increasingly performed. There are no data on long-term outcomes after aortic ViV. Our aim was to perform a large-scale assessment of long-term survival and reintervention after aortic ViV. METHODS AND RESULTS: A total of 1006 aortic ViV procedures performed more than 5 years ago [mean age 77.7 ± 9.7 years; 58.8% male; median STS-PROM score 7.3% (4.2-12.0)] were included in the analysis. Patients were treated with Medtronic self-expandable valves (CoreValve/Evolut, Medtronic Inc., Minneapolis, MN, USA) (n = 523, 52.0%), Edwards balloon-expandable valves (EBEV, SAPIEN/SAPIEN XT/SAPIEN 3, Edwards Lifesciences, Irvine, CA, USA) (n = 435, 43.2%), and other devices (n = 48, 4.8%). Survival was lower at 8 years in patients with small-failed bioprostheses [internal diameter (ID) ≤ 20 mm] compared with those with large-failed bioprostheses (ID > 20 mm) (33.2% vs. 40.5%, P = 0.01). Independent correlates for mortality included smaller-failed bioprosthetic valves [hazard ratio (HR) 1.07 (95% confidence interval (CI) 1.02-1.13)], age [HR 1.21 (95% CI 1.01-1.45)], and non-transfemoral access [HR 1.43 (95% CI 1.11-1.84)]. There were 40 reinterventions after ViV. Independent correlates for all-cause reintervention included pre-existing severe prosthesis-patient mismatch [subhazard ratio (SHR) 4.34 (95% CI 1.31-14.39)], device malposition [SHR 3.75 (95% CI 1.36-10.35)], EBEV [SHR 3.34 (95% CI 1.26-8.85)], and age [SHR 0.59 (95% CI 0.44-0.78)]. CONCLUSIONS: The size of the original failed valve may influence long-term mortality, and the type of the transcatheter valve may influence the need for reintervention after aortic ViV.

BACKGROUND: The prevalence of both chronic kidney disease (CKD) and aortic stenosis (AS) increase with age. Although baseline CKD is frequent in patients undergoing transcatheter aortic valve replacement (TAVR), its significance among women is largely unknown. METHODS: Women's INternational Transcatheter Aortic Valve Implantation (WIN-TAVI) is a multinational, prospective registry of women undergoing TAVR for severe AS. We included patients with available baseline estimated glomerular filtration rate (eGFR) and completed 1-year follow-up. Patients were categorized into three groups based on their eGFR: No CKD (normal kidney function to stage 2 CKD: eGFR ≥60 ml/min/1.73 m2 ); (b) mild CKD (stage 3a CKD: eGFR = 45-59 ml/min/1.73 m2 ); and (c) moderate/severe CKD (stage ≥3b CKD: eGFR <45 ml/min/1.73 m2 ). All events were adjudicated according to the Valve Academic Research Consortium (VARC)-2 criteria. RESULT: Out of 852 women undergoing TAVR, 326 (38.3%) had no CKD, 225 (26.4%) had mild CKD, and 301 (35.3%) had moderate/severe CKD. Women with higher stage of CKD at baseline were more likely to have a history of hypertension, diabetes, atrial fibrillation, anemia, chronic lung disease, hemodialysis, prior percutaneous coronary intervention, and pacemaker implantation. After multivariate adjustment, moderate/severe CKD was associated with a greater risk of 1-year VARC-2 safety endpoints [hazard ratio (HR) 1.68, 95% confidence interval (CI): 1.10-2.60], all-cause death (HR 2.00, 95% CI: 1.03-3.90), and composite of death, myocardial infarction, stroke or life-threatening bleeding (HR 1.70, 95% CI: 1.04-2.76). There were no differences in 30-day and 1-year VARC-2 efficacy and 30-day VARC-2 safety outcomes. CONCLUSION: CKD is associated with substantial and independent risk for mortality and morbidity at 1-year follow-up in women undergoing TAVR.

OBJECTIVES: To evaluate the impact of coronary artery disease (CAD) with or without recent (≤ 30 days) percutaneous coronary intervention (PCI) in women undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND: Although women display a specific risk-profile for both PCI and TAVR, the impact of CAD and PCI in the setting of TAVR in women is unclear. METHODS: The multinational Women's International Transcatheter Aortic Valve implantation registry enrolled consecutive female patients undergoing contemporary TAVR in 19 centers between 2013 and 2015. Patients with available coronary angiography or CT scan in the pre-operative assessment of TAVR were categorized as without CAD, with CAD but no recent PCI and CAD and recent PCI (≤30 days). All events were adjudicated according to the VARC-2 criteria. RESULTS: A total of 787 patients were included in this analysis, among whom 459 (58.3%) had no CAD, 247 (31.4%) had CAD without recent PCI and 81 (10.3%) underwent recent PCI (≤ 30 days before TAVR). After multivariable adjustment, both groups of CAD patients, without and with recent PCI, presented with higher risk of death, myocardial infarction or stroke, compared with patients without CAD (adj HR 1.56, 95%CI 1.03-2.39, P = 0.038 and adj HR 1.96, 95% CI 1.1-3.5, P = .021, respectively). Patients with recent PCI had increased risk of all-cause death (adj HR 1.89, 95% CI 1.0-3.5, P = 0.04) and stroke (adj HR 3.7, 95% CI 1.0-13.5, P = 0.046) compared with patients without CAD. CONCLUSION: The presence of CAD in women undergoing TAVR, with or without recent PCI, was associated with long-term poorer outcomes.

Aims: There are limited data on coronary obstruction following transcatheter valve-in-valve (ViV) implantation inside failed aortic bioprostheses. The objectives of this study were to determine the incidence, predictors, and clinical outcomes of coronary obstruction in transcatheter ViV procedures. Methods and results: A total of 1612 aortic procedures from the Valve-in-Valve International Data (VIVID) Registry were evaluated. Data were subject to centralized blinded corelab computed tomography (CT) analysis in a subset of patients. The virtual transcatheter valve to coronary ostium distance (VTC) was determined. A total of 37 patients (2.3%) had clinically evident coronary obstruction. Baseline clinical characteristics in the coronary obstruction patients were similar to controls. Coronary obstruction was more common in stented bioprostheses with externally mounted leaflets or stentless bioprostheses than in stented with internally mounted leaflets bioprostheses (6.1% vs. 3.7% vs. 0.8%, respectively; P < 0.001). CT measurements were obtained in 20 (54%) and 90 (5.4%) of patients with and without coronary obstruction, respectively. VTC distance was shorter in coronary obstruction patients in relation to controls (3.24 ± 2.22 vs. 6.30 ± 2.34, respectively; P < 0.001). Using multivariable analysis, the use of a stentless or stented bioprosthesis with externally mounted leaflets [odds ratio (OR): 7.67; 95% confidence interval (CI): 3.14-18.7; P < 0.001] associated with coronary obstruction for the global population. In a second model with CT data, a shorter VTC distance predicted this complication (OR: 0.22 per 1 mm increase; 95% CI: 0.09-0.51; P < 0.001), with an optimal cut-off level of 4 mm (area under the curve: 0.943; P < 0.001). Coronary obstruction was associated with a high 30-day mortality (52.9% vs. 3.9% in the controls, respectively; P < 0.001). Conclusion: Coronary obstruction following aortic ViV procedures is a life-threatening complication that occurred more frequently in patients with prior stentless or stented bioprostheses with externally mounted leaflets and in those with a short VTC.

BACKGROUND: Conflicting evidence exists on the efficacy and safety of bivalirudin administered as part of percutaneous coronary intervention (PCI) in patients with an acute coronary syndrome. METHODS: We randomly assigned 7213 patients with an acute coronary syndrome for whom PCI was anticipated to receive either bivalirudin or unfractionated heparin. Patients in the bivalirudin group were subsequently randomly assigned to receive or not to receive a post-PCI bivalirudin infusion. Primary outcomes for the comparison between bivalirudin and heparin were the occurrence of major adverse cardiovascular events (a composite of death, myocardial infarction, or stroke) and net adverse clinical events (a composite of major bleeding or a major adverse cardiovascular event). The primary outcome for the comparison of a post-PCI bivalirudin infusion with no post-PCI infusion was a composite of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events. RESULTS: The rate of major adverse cardiovascular events was not significantly lower with bivalirudin than with heparin (10.3% and 10.9%, respectively; relative risk, 0.94; 95% confidence interval [CI], 0.81 to 1.09; P=0.44), nor was the rate of net adverse clinical events (11.2% and 12.4%, respectively; relative risk, 0.89; 95% CI, 0.78 to 1.03; P=0.12). Post-PCI bivalirudin infusion, as compared with no infusion, did not significantly decrease the rate of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events (11.0% and 11.9%, respectively; relative risk, 0.91; 95% CI, 0.74 to 1.11; P=0.34). CONCLUSIONS: In patients with an acute coronary syndrome, the rates of major adverse cardiovascular events and net adverse clinical events were not significantly lower with bivalirudin than with unfractionated heparin. The rate of the composite of urgent target-vessel revascularization, definite stent thrombosis, or net adverse clinical events was not significantly lower with a post-PCI bivalirudin infusion than with no post-PCI infusion.

OBJECTIVES: To compare the long-term clinical outcomes of paclitaxel drug-coated-balloons (DCB) and everolimus-eluting-stents (EES) following the treatment of de novo small vessel coronary artery disease. BACKGROUND: It is currently unclear whether treatment of de novo small vessel coronary disease with DCB is comparable to second generation drug-eluting stents, which are the current standard of care. METHODS: The present study enrolled 90 patients with small vessel coronary disease from the DCB treatment arm of the BELLO (Balloon Elution and Late Loss Optimization) trial and 2,000 patients treated with EES at the San Raffaele Scientific Institute. Propensity score matching was performed to adjust for differences in baseline clinical and angiographic characteristics, yielding a total of 181 patients: 90 patients with 94 lesions receiving DCB and 91 patients with 94 lesions receiving EES. Major adverse cardiac events (MACE) were defined as the composite of cardiac death, recurrent non-fatal myocardial infarction, and target vessel revascularization. RESULTS: After propensity score matching, baseline clinical and angiographic characteristics were similar between the two groups. The cumulative MACE rate at 1-year was 12.2% with DCB and 15.4% with EES (P = 0.538). Patients in the DCB group had similar TLR rates as compared to EES over the same interval (4.4% vs. 5.6%; P = 0.720). There were no cases of definite or probable stent or vessel thrombosis. CONCLUSIONS: The use of paclitaxel-DCB appears to be associated with similar clinical outcomes when compared to second-generation-EES in small coronary artery disease. The findings of this study should be confirmed with larger prospective randomized studies with longer follow-up. © 2017 Wiley Periodicals, Inc.

BACKGROUND: It is unclear whether radial compared with femoral access improves outcomes in unselected patients with acute coronary syndromes undergoing invasive management. METHODS: We did a randomised, multicentre, superiority trial comparing transradial against transfemoral access in patients with acute coronary syndrome with or without ST-segment elevation myocardial infarction who were about to undergo coronary angiography and percutaneous coronary intervention. Patients were randomly allocated (1:1) to radial or femoral access with a web-based system. The randomisation sequence was computer generated, blocked, and stratified by use of ticagrelor or prasugrel, type of acute coronary syndrome (ST-segment elevation myocardial infarction, troponin positive or negative, non-ST-segment elevation acute coronary syndrome), and anticipated use of immediate percutaneous coronary intervention. Outcome assessors were masked to treatment allocation. The 30-day coprimary outcomes were major adverse cardiovascular events, defined as death, myocardial infarction, or stroke, and net adverse clinical events, defined as major adverse cardiovascular events or Bleeding Academic Research Consortium (BARC) major bleeding unrelated to coronary artery bypass graft surgery. The analysis was by intention to treat. The two-sided α was prespecified at 0·025. The trial is registered at ClinicalTrials.gov, number NCT01433627. FINDINGS: We randomly assigned 8404 patients with acute coronary syndrome, with or without ST-segment elevation, to radial (4197) or femoral (4207) access for coronary angiography and percutaneous coronary intervention. 369 (8·8%) patients with radial access had major adverse cardiovascular events, compared with 429 (10·3%) patients with femoral access (rate ratio [RR] 0·85, 95% CI 0·74-0·99; p=0·0307), non-significant at α of 0·025. 410 (9·8%) patients with radial access had net adverse clinical events compared with 486 (11·7%) patients with femoral access (0·83, 95% CI 0·73-0·96; p=0·0092). The difference was driven by BARC major bleeding unrelated to coronary artery bypass graft surgery (1·6% vs 2·3%, RR 0·67, 95% CI 0·49-0·92; p=0·013) and all-cause mortality (1·6% vs 2·2%, RR 0·72, 95% CI 0·53-0·99; p=0·045). INTERPRETATION: In patients with acute coronary syndrome undergoing invasive management, radial as compared with femoral access reduces net adverse clinical events, through a reduction in major bleeding and all-cause mortality.

OBJECTIVES: The aim of this study is to describe the cerebral ischemia recurrence rate after percutaneous patent foramen ovale (PFO) closure in patients older than 55 years and their outcomes, compared with younger patients. BACKGROUND: The registries data and the recent randomized trials about PFO closure are focused on patients younger than 55 years. Little is known about older patients' long-term outcome. METHODS: In total, 458 patients underwent PFO closure for cryptogenic cerebral ischemia and were stratified into an "older" (≥ 55 years, 151 patients) and a "younger" (<55 years, 307 patients) group. RESULTS: Older patients had mean age of 63 ± 6 years and more atrial septum aneurysm (P = 0.05), hypertension, diabetes, and dyslipidemia (P = 0.001). Mean followup was 4.5 ± 2.8 years. Older patients had a higher rate of ischemic recurrence (0.3 vs. 4.0%, P = 0.002), after a mean time of 3.1 ± 2.6 years. The Kaplan-Meier curve confirmed higher event-free survival in the youngers (P = 0.008). None of the patients with ischemic recurrence had significant residual shunt. Age and hypertension were correlated to ischemic recurrence, but age was the only independent predictor at multivariate analysis. CONCLUSIONS: Recurrent cerebral ischemia after PFO closure is more frequent in older patients and could most likely be associated to conditions related to age (atherosclerosis, atrial fibrillation), than to paradoxical embolism. The procedure is as safe as in younger patients.

OBJECTIVES: We aimed to investigate procedural feasibility and outcomes associated with planned rotational atherectomy (RA) for severely calcified coronary lesions. BACKGROUND: Limited data are available addressing the benefits of planned RA compared to provisional RA. METHODS: Between 2002 and 2013, all patients with calcified lesions treated by RA were enrolled. Of these, patients treated with planned RA (358 patients) were compared to those treated with provisional RA (309 patients). RESULTS: In-hospital major adverse cardiovascular events (MACE) were tended to be better in the planned RA group (unadjusted OR: 0.76; 95% CI: 0.44-1.31, P = 0.32, and adjusted OR: 0.59; 95% CI: 0.33-1.05, P = 0.07). The number of pre-dilation balloon catheters was significantly lower in the planned RA group (1.17 ± 0.60 vs. 1.47 ± 0.76, P < 0.001). Procedure time, fluoroscopy time, and contrast volume used were all significantly reduced in the planned RA group compared to the provisional RA group (procedure time; 65.2 ± 36.8min vs. 84.4 ± 43.1min, P < 0.001, fluoroscopy time; 33.1 ± 22.9min vs. 51.2 ± 29.6min, P < 0.001, and contrast volume; 232.9 ± 141.6ml vs. 302.9 ± 150.3ml, P < 0.001). The incidence of MACE at 1-year was significantly higher amongst the unadjusted population, whereas the difference was less marked between groups after propensity-score adjustment (unadjusted HR: 1.78; 95% CI: 1.16-2.74, P = 0.01, and adjusted HR: 1.44; 95% CI: 0.92-2.26, P = 0.11). CONCLUSIONS: Planned RA appears to be safe and was associated with a reduction in procedural and fluoroscopy times, contrast volume, and the number of pre-dilation balloon catheters used. If there is a strong likelihood of requiring RA for the treatment of severely calcified lesions, operators should have a low threshold for adopting a planned RA strategy. © 2016 Wiley Periodicals, Inc.

BACKGROUND: The aim of this study was to assess the impact of bivalirudin, as compared to unfractionated heparin, on clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: A meta-analysis of randomized trials comparing bivalirudin versus heparin in patients with STEMI undergoing primary percutaneous coronary intervention was performed. Three randomised trials enrolling 7,612 patients were included. Analysis was by intention to treat. RESULTS: At 30 days, bivalirudin, as compared to heparin, was associated with a similar risk of all-cause mortality (3.03% vs. 3.38%, odds ratio (OR) 0.90, 95% confidence intervals (CI) [0.63 to 1.29], P = 0.57). Bivalirudin significantly increased the risk of definite (2.39% vs. 1.06%, OR 2.49, 95% CI [1.30 to 4.76], P = 0.006); definite or probable (2.55% vs. 1.35%, OR 2.26, 95% CI [1.07 to 4.79], P = 0.03), and acute stent thrombosis (1.69% vs. 0.39%, OR 4.34, 95% CI [2.30 to 8.16], P < 0.001); leading to nonsignificantly higher reinfarction rates (2.0% vs. 1.31%, OR 1.72, 95% CI [0.89 to 3.35], P = 0.11), and to a significantly increased risk of ischemia driven revascularization (2.50% vs. 1.52%, OR 1.80, 95% CI [1.02 to 3.18], P = 0.04) at 30 days. No firm evidence for a reduction in major bleeding associated with bivalirudin use was found (3.93% vs. 6.39%, OR 0.63, 95% CI [0.39 to 1.04], P = 0.07). CONCLUSIONS: In patients with STEMI, bivalirudin, as compared to heparin, increases the risk of stent thrombosis and ischemia driven repeat revascularization at 30 days. There is no strong evidence that bivalirudin significantly reduces major bleeding at 30 days. Bivalirudin does not have an effect on all-cause mortality at 30 days.

Regurgitation due to a paravalvular leak (PVL) is a complication that may affect patients undergoing surgical mechanical or bioprosthetic heart valve replacement. PVL can also occur after transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis and is associated with significantly worse outcomes. We report a case in which different closure strategies and devices were attempted and required to percutaneously close a severe PVL after TAVI in a patient with prohibitive surgical risk.

In view of the high number of bioprosthetic valves implanted during the past 30 years, an increasing number of patients are coming to medical attention because of degenerated bioprostheses. Transcatheter aortic valve-in-valve implantation has been described as a less invasive alternative to re-operation to treat severe structural valve deterioration. As far as degenerated mitral valve bioprostheses are concerned, transcatheter transapical mitral valve-in-valve replacement (TMVR) has been less commonly performed, but may also become a viable alternative to re-do replacement surgery. We describe treatment of a degenerated bioprosthetic mitral valve, characterised by complete absence of any radio-opaque landmarks making the TMVR procedure very challenging.

Transcatheter aortic valve implantation (TAVI) has emerged as a feasible and effective alternative to aortic valve replacement in patients at high surgical risk, and is associated with a lower risk of death at 1 year follow-up when compared with standard therapy. In a recent large study, enrolling 663 high risk patients with symptomatic severe aortic stenosis TAVI with the use of CoreValve system has been associated with early and sustained clinical and hemodynamic benefits, with a cumulative mortality of 15.0% at 1 year follow-up. This study has shown that paravalvular aortic regurgitation after successful TAVI is a frequent finding, being of mild entity in the vast majority of cases, whereas valvular regurgitation is almost entirely absent or mild. Of note, no cases of structural valve deterioration were reported. We report a case of a successful implantation of a CoreValve that complicated with late onset massive intravalvular aortic regurgitation, due to CoreValve cusp rupture, leading to low output state with acute pulmonary edema, which was successfully treated with "valve in valve" implantation.

BACKGROUND: The impact of female sex on mortality after transcatheter aortic valve implantation (TAVI) is controversial. Post-procedural aortic regurgitation (AR) ≥ 2 has been associated with poor outcomes. Whether sex differences in post-procedural AR ≥ 2 could contribute to a mortality difference between women and men is not known. METHODS: Six hundred fifty-six patients, women (53.1%), men (46.9%), with aortic stenosis underwent TAVI with the CoreValve system (92.8%) or the Edwards SAPIEN valve system (7.2%). AR was graded semiquantitatively as 0 = none, 1 = trivial, 2 = mild, 3 = moderate, and 4 = severe. The incidence of post-procedural AR ≥ 2 was reported. RESULTS: Procedural success was similar in women as compared to men (97.9 vs 96.7%, P = 0.32). Post-procedural AR ≥ 2 occurred less frequently in women than in men (20.9 vs 29.6%, P = 0.01). After a median follow-up of 434 days, all-cause mortality tended to be lower in women than in men (20.7 vs 26.6%, logrank P = 0.10), and was significantly higher in patients with AR ≥ 2 than in those without (34.8 vs 19.7%, logrank P < 0.001). AR ≥ 2 [hazard ratio (HR) 1.73, 95% confidence interval (CI) 1.22-2.43, P = 0.002], but not female sex (P = 0.17) was an independent predictor of all-cause death at multivariable Cox regression. The predictive value of AR ≥ 2 was restricted to men (HR 2.96, P < 0.001 among men; HR 0.86, P = 0.60 among women; P for interaction = 0.002). CONCLUSIONS: Women, as compared to men, present a trend toward lower mortality. A significant lower incidence of post-procedural AR ≥ 2 among women contributes to this finding. Female sex, however, was not a significant independent predictor of death.

AIMS: Impact of periprocedural bleeding after transcatheter aortic valve implantation (TAVI) over mid-term prognosis remains still unclear. METHODS: Consecutive patients who underwent TAVI from May 2008 to July 2012 were prospectively included and stratified according to life-threatening (LT) and major bleeding (MB). Mid-term all-cause death was the primary end-point, and 30-day death, vascular complications, stroke, and acute kidney injury the secondary ones. All end-points were adjudicated according to VARC. RESULTS: Seven hundred fourteen patients with an average age of 81.9 ± 5.8 years were included. 130 (18%) patients suffered a LT, 112 (16%) a MB. A preprocedural GFR <30 ml/min and increasing diameter of sheaths were independent predictors of LT or MB, while transfemoral approach showed a protective effect (OR 0.42; CI: 0.26-0.68; P = 0.035). At 30 days LT (OR 3.3; CI: 1.1-9.7; P = 0.0026) and MB (OR 3.5; CI: 1.4-8.6; P = 0.007) bleeding along with GFR < 30 ml/min (OR 2.3; CI: 1.1-5.5; P = 0.04) were independent predictors of death, while bleeding did not impact survival on mid term (OR 0.9; CI: 0.47-1.7; P = 0.78; all CI 95%). CONCLUSION: Periprocedural bleeding after TAVI was frequent and associated with an increased mortality after 30 days but not after mid-term follow-up. A preprocedural GFR < 30 ml/min was the most important predictor of bleeding, enabling risk stratification and choice of approach for these patients.

AIMS: To analyse the clinical outcome at 4 years in patients with coronary artery disease treated with bare metal stents (BMS) vs. BMS and oral prednisone, or drug-eluting stents (DES), all assuming similar adjunctive medical treatment. METHODS AND RESULTS: Five Italian hospitals enrolled 375 non-diabetic, ischaemic patients without contraindications to dual anti-platelet treatment or corticosteroid therapy in a randomized controlled study. The primary endpoint was the event-free survival of cardiovascular death, myocardial infarction, and recurrence of ischaemia needing repeated target vessel revascularization at 1 year, and this was significantly lower in the BMS group (80.8%) compared with the prednisone (88.0%) and DES group (88.8%, P = 0.04 and 0.006, respectively). The long-term analysis of the primary endpoint was a pre-specified aim of the trial, and was performed at 1447 days (median, IQ range = 1210-1641). Patients receiving BMS alone had significantly lower event-free survival (75.3%) compared with 84.1% in the prednisone group (HR: 0.447; 95% CI: 0.25-0.80, P = 0.007) and 80.6% in DES patients (HR: 0.519; 95% CI: 0.29-0.93, P = 0.03). Prednisone-treated patients did not develop new treatment-related clinical problems. Drug-eluting stents patients suffered more very late stent thrombosis as a cause of spontaneous myocardial infarction. The need for target vessel revascularization remained lower in the prednisone and DES groups (13.6 and 15.2%, respectively), compared with BMS (23.2%). CONCLUSIONS: The clinical benefits of prednisone compared with BMS only persisted almost unchanged at 4 years. Drug-eluting stents performed better than BMS at long-term, although the advantages observed at 1 year were in part attenuated because of the occurrence of very late stent thrombosis and late revascularizations. Clinical Trial NCT 00369356.
