RESUMEN
INTRODUCTION AND OBJECTIVES: Impact of gender on long-term outcomes after transcatheter aortic valve implantation (TAVI) remains uncertain. We aimed to investigate gender-specific differences in TAVI and its impact on outcomes. METHODS: This analysis used data from the prospective Spanish TAVI registry, which included consecutive TAVI patients treated in 46 Spanish centers from 2009 to 2021. The primary endpoint was all-cause mortality at 12 months. Secondary endpoints included in-hospital and 30-day mortality and TAVI-related complications. Adjusted logistic and Cox regression analyses were performed. RESULTS: The study included 12 253 consecutive TAVI patients with a mean age of 81.2 ± 6.4 years. Women (53.9%) were older, and had a higher STS-PROM score (7.0 ± 7.0 vs 6.2 ± 6.7; P < .001) than men. Overall, the TAVI-related complication rate was similar between women and men, with specific gender-related complications. While women more frequently developed in-hospital vascular complications (13.6% vs 9.8%; P < .001) and cardiac tamponade (1.5% vs 0.6%; P = .009), men showed a higher incidence of permanent pacemaker implantation (14.5% vs 17.4%; P = .009). There was no difference in all-cause mortality either in hospital (3.6% vs 3.6%, adjusted odds ratio [OR], 1.01; 95% confidence interval [95%CI], 0.83-1.23; P = .902), at 30 days (4.2% vs 4.2%, adjusted OR, 0.90; 95%CI, 0.65-1.25; P = .564) or at 1 year (11% vs 13%, adjusted HR, 0.94; [0.80-1.11]; P = .60). CONCLUSIONS: women treated with TAVI are older and have more comorbidities than men, leading to distinct complications between genders. Nevertheless, all-cause mortality in the short-term and at 1-year was similar between men and women.
RESUMEN
The improvement in survival rates in pediatric malignancies has led to an increase in the number of cancer survivors who are at risk of developing cardiotoxicity and heart failure. Cardiac dysfunction in these patients can occur asymptomatically, and the diagnosis in a symptomatic phase is associated with reduced treatment response and worse prognosis. For this reason, it is essential to establish protocols to follow up on these patients and identify those at risk of cardiotoxicity in order to start early and effective therapies. This review aims to summarize the latest findings in the diagnosis and treatment of cancer therapy-related cardiac disease in long-term survivors of childhood cancer, with a focus on heart failure.
RESUMEN
BACKGROUND: The off-label utilization of transcatheter heart valve (THV) devices for the treatment of inoperable or high-surgical risk patients with pure native aortic valve regurgitation (NAVR) has demonstrated suboptimal outcomes, both with self- and balloon-expandable (BE) devices. The aim of this study is to compare the use of different BE scaffolds in treating pure NAVR. METHODS: Consecutive patients with pure severe NAVR who were deemed to be at high-risk and were treated with last-generation BE-THVs among seventeen Centers in Europe and US. Technical and device success rates were the primary objectives. RESULTS: Between February 2018 and July 2023, among 144 patients, 41 (28 %) received a MyVal device and 103 (72 %) were treated with a Sapien THV. Patients treated with a MyVal THV had an extra-large annulus more frequently compared to the Sapien group (49%vs.20 %, p < 0.001). Technical and device success rates were 90 % and 81 %, respectively, p > 0.1. The rate of THV migration/embolization (MyVal 4.9%vs. Sapien 11 %, p = 0.4) and second valve needed (4.9%vs.7.8 %, p = 0.7) were numerically lower in the MyVal group, whereas the rate of at least moderate paravalvular leak (15%vs.7.8 %, p = 0.2) and permanent pacemaker implantation (25%vs.18 %, p = 0.16) were numerically higher in the Myval group. CONCLUSIONS: Off-label use of BE devices for pure NAVR represents a potential alternative in high-risk patients in the absence of dedicated devices. However, BE in NAVR is associated with suboptimal outcomes. The availability of larger THV sizes may introduce transcatheter aortic valve replacement as an effective treatment for patients traditionally deemed unsuitable. NON-STANDARD ABBREVIATIONS AND ACRONYMS: AR = aortic regurgitation, BE = balloon-expandable, NAVR = native aortic valve regurgitation, PM = pacemaker, TAVR = transcatheter aortic valve replacement, THV = transcatheter heart valve, TVEM = transcatheter valve embolization and migration, VARC-3 = Valve Academic Research Consortium 3.
RESUMEN
Introduction: There is current controversy surrounding the benefits of percutaneous coronary intervention (PCI) of chronic total coronary occlusions (CTO). We aimed to evaluate the impact of complete percutaneous revascularization on major adverse cardiovascular events (MACE) in patients with CTO. Methods: A retrospective observational study was conducted of consecutive patients referred for invasive coronary angiography at a single center between January 2018 and December 2019 and at least a CTO. The patients were divided into two groups according to the result of the procedure: complete revascularization of CTO (CR-CTO) versus incomplete revascularization (ICR-CTO) (patients with at least one non-recanalized CTO). Short- and mid-term clinical outcomes were evaluated. The primary endpoint was a composite of MACE that included all-cause death, non-fatal myocardial infarction, non-fatal stroke, or unplanned revascularization. Results: In total, 359 patients with CTO were included. The median age was 68 years [interquartile range (IQR) 60-77 years], 66 (18%) were women and 169 (47.3%) had diabetes mellitus. In all, 167 (46.5%) patients received complete revascularization. After a median follow-up of 42 months (IQR 46-50 months), the primary endpoint occurred in 39 (23.4%) patients in the CR-CTO group and in 75 (39.1%) in the ICR-CTO group (HR 0.50, 95% CI 0.34-0.74; p < 0.001). This association remained significant in an inverse probability weighted model considering prognostic factors (adjusted HR 0.61, 95% CI 0.41-0.92; p = 0.018) and was driven by lower rates of all-cause death (adjusted OR 0.50, 95% CI 0.23-0.84; p = 0.01). Conclusions: Complete revascularization of CTO was associated with a lower risk of MACE in the midterm follow up.
RESUMEN
Background. Despite technical advancements, patients with sequential or diffuse coronary lesions undergoing percutaneous coronary intervention (PCI) have an increased risk of cardiovascular events at follow-up. We aimed to analyze the utility of a SyncVision/iFR (S-iFR)-guided PCI strategy versus an angiography-guided strategy in patients with this type of lesions. Methods. Randomized, multicenter, controlled, and open-label trial to compare S-iFR versus angiography-guided PCI in patients with sequential or diffuse angiographic coronary stenosis (ClinicalTrials.gov identifier: NCT04283734). The primary endpoint was the implanted stent length. The main secondary endpoint was targeting vessel failure (TVF) at one year. Results. A total of 100 patients underwent randomization, with 49 patients assigned to the S-iFR group and 51 to the angiography-guided PCI group. There were no differences between groups regarding clinical and anatomical characteristics. The baseline iFR was 0.71 ± 0.16 vs. 0.67 ± 0.19 (p = 0.279) in the S-iFR and angiography group, respectively. The mean lesion length was 42.3 ± 12 mm and 39.8 ± 12 (p = 0.297). The implanted stent length was 32.7 ± 17.2 mm in the S-iFR group and 43.1 ± 14.9 mm in the angiography group (mean difference, -10.4 mm; 95% confidence interval [CI], -16.9 to -4.0; p = 0.002). At one year, target vessel failure (TVF) occurred in four patients: three (6.1%) in the S-iFR group vs. one (1.9%) in the angiography group (p = 0.319). Conclusions. Among patients with sequential or long diffuse coronary lesions, a S-iFR-guided PCI strategy resulted in a reduction of the total stent length compared to an angiography-guided PCI strategy. A nonsignificant increase in TVF was observed in the S-iFR group.
RESUMEN
BACKGROUND: Transcatheter aortic valve implantation is an established, guideline-endorsed treatment for severe aortic stenosis. Precise sizing of the balloon-expandable Myval transcatheter heart valve (THV) series with the aortic annulus is facilitated by increasing its diameter in 1·5 mm increments, compared with the usual 3 mm increments in valve size. The LANDMARK trial aimed to show non-inferiority of the Myval THV series compared with the contemporary THVs Sapien Series (Edwards Lifesciences, Irvine, CA, USA) or Evolut Series (Medtronic, Minneapolis, MN, USA). METHODS: In this prospective, multinational, randomised, open-label, non-inferiority trial across 31 hospitals in 16 countries (Germany, France, Sweden, the Netherlands, Italy, Spain, New Zealand, Portugal, Greece, Hungary, Poland, Slovakia, Slovenia, Croatia, Estonia, and Brazil), 768 participants with severe symptomatic native aortic stenosis were randomly assigned (1:1) to the Myval THV or a contemporary THV. Eligibility was primarily decided by the heart team in accordance with 2021 European Society of Cardiology guidelines. As per the criteria of the third Valve Academic Research Consortium, the primary endpoint at 30 days was a composite of all-cause mortality, all stroke, bleeding (types 3 and 4), acute kidney injury (stages 2-4), major vascular complications, moderate or severe prosthetic valve regurgitation, and conduction system disturbances resulting in a permanent pacemaker implantation. Non-inferiority of the study device was tested in the intention-to-treat population using a non-inferiority margin of 10·44% and assuming an event rate of 26·10%. This trial is registered with ClinicalTrials.gov, NCT04275726, and EudraCT, 2020-000137-40, and is closed to new participants. FINDINGS: Between Jan 6, 2021, and Dec 5, 2023, 768 participants with severe symptomatic native aortic stenosis were randomly assigned, 384 to the Myval THV and 384 to a contemporary THV. 369 (48%) participants had their sex recorded as female, and 399 (52%) as male. The mean age of participants was 80·0 years (SD 5·7) for those treated with the Myval THV and 80·4 years (5·4) for those treated with a contemporary THV. Median Society of Thoracic Surgeons scores were the same in both groups (Myval 2·6% [IQR 1·7-4·0] vs contemporary 2·6% [1·7-4·0]). The primary endpoint showed non-inferiority of the Myval (25%) compared with contemporary THV (27%), with a risk difference of -2·3% (one-sided upper 95% CI 3·8, pnon-inferiority<0·0001). No significant difference was seen in individual components of the primary composite endpoint. INTERPRETATION: In individuals with severe symptomatic native aortic stenosis, the Myval THV met its primary endpoint at 30 days. FUNDING: Meril Life Sciences.

The 2023 European Bifurcation Club (EBC) meeting took place in Warsaw in October, and the latest evidence for the use of intravascular ultrasound (IVUS) and optical coherence tomography (OCT) to optimise percutaneous coronary interventions (PCI) on coronary bifurcation lesions (CBLs) was a major focus. The topic generated deep discussions and general appraisal on the potential benefits of IVUS and OCT in PCI procedures. Nevertheless, despite an increasing recognition of IVUS and OCT capabilities and their recognised central role for guidance in complex CBL and left main PCI, it is expected that angiography will continue to be the primary guidance modality for CBL PCI, principally due to educational and economic barriers. Mindful of the restricted access/adoption of intracoronary imaging for CBL PCI, the EBC board decided to review and describe a series of tips and tricks which can help to optimise angiography-guided PCI for CBLs. The identified key points for achieving an optimal angiography-guided PCI include a thorough analysis of pre-PCI images (computed tomography angiography, multiple angiographic views, quantitative coronary angiography vessel estimation), a systematic application of the technical steps suggested for a given selected technique, an intraprocedural or post-PCI use of stent enhancement and a low threshold for bailout use of intravascular imaging.

The following letter presents an answer of a comment of our work titled "Ross procedure: valve function, clinical outcomes and predictors after 25 years' follow-up," recently published in your journal by Rangwala et al.1 As our colleagues point out, the Ross procedure has excellent survival rates but a significant risk of valve dysfunction and therefore reintervention at follow-up. Although the survival advantage with the Ross procedure appears to be consistent compared with mechanical valve substitutes, this benefit is not as clear compared with biological valve substitutes. However, biological valve substitutes also have significant reintervention rates during follow-up. The different surgical modifications of the Ross procedure have not clearly demonstrated better results in follow-up in terms of autograft reintervention. This procedure can be performed in a medium-volume center with good results as long as adequate patient selection and adequate surgical training are carried out.

OBJECTIVE: To describe long-term outcomes of the Ross procedure in a single center and retrospective series after 25 years follow-up. METHODS: From 1997-2019 we included all consecutive patients who underwent Ross procedure at our center. Clinical and echocardiographic evaluations were performed at least yearly. Echocardiographic valvular impairment was defined as at least moderate autograft or homograft dysfunction. Reintervention outcomes included surgical and percutaneous approach. RESULTS: 151 Ross procedures were performed (mean age 28±12years, 21 %<16years, 70 %male). After 25 years follow-up (median 18 years, interquartile range 9-21, only 3 patients lost) 12 patients died (8 %); Autograft, homograft or any valve dysfunction were present in 38(26 %), 48(32 %) and 75(51 %), respectively; and reintervention in 22(15%), 17(11%) and 38(26 %) respectively. At 20 years of follow-up, probabilities of survival free from autograft, homograft or any valve dysfunction were 63 %, 60 % and 35 %; and from reintervention, 80 %, 85 % and 67 %, respectively. The learning curve period (first 12 cases) was independently associated to autograft dysfunction (HR 2.78, 95 %CI:1.18-6.53, p = 0.02) and reintervention (HR 3.76, 95 %CI: 1.46-9.70, p = 0.006). Larger native pulmonary diameter was also an independent predictor of autograft reintervention (HR 1.22, 95 %CI:1.03-1.45, p = 0.03). Homograft dysfunction was associated with younger age (HR 5.35, 95 %CI: 2.13-13.47, p<0.001) and homograft reintervention, with higher left ventricle ejection fraction (HR 1,10, 95 %CI:1.02-1.19, p<0.02). CONCLUSIONS: In this 25 years' experience after the Ross procedure, global survival was high, although autograft and homograft dysfunction and reintervention rates were not negligible. Clinical and echocardiographic variables can identify patients with higher risk of events in follow up.

INTRODUCTION AND OBJECTIVES: Survivors of childhood cancer might be at increased risk of diastolic dysfunction at follow-up due to exposure to cardiotoxic treatment. Although assessment of diastolic function is challenging in this relatively young population, left atrial strain might provide a novel insight in this evaluation. Our aim was to examine diastolic function in a cohort of long-term survivors of childhood acute lymphoblastic leukemia by using left atrial strain and conventional echocardiographic parameters. METHODS: Long-term survivors who were diagnosed at a single center between 1985 and 2015 and a control group of healthy siblings were recruited. Conventional diastolic function parameters and atrial strain were compared, and the latter was measured during the 3 atrial phases: reservoir (PALS), conduit (LACS) and contraction (PACS). Inverse probability of treatment weighting was used to account for differences between the groups. RESULTS: We analyzed 90 survivors (age, 24.6±9.7 years, time since diagnosis 18 [11-26] years) and 58 controls. PALS and LACS were significantly reduced compared with the control group: 46.4±11.2 vs 52.1±11.7; P=.003 and 32.5±8.8 vs 38.2±9.3; P=.003, respectively. Conventional diastolic parameters and PACS were similar between the groups. The reductions in PALS and LACS were associated with exposure to cardiotoxic treatment in age- and sex-adjusted analysis (≥ moderate risk, low risk, controls): 45.4±10.5, 49.5±12.9, 52.1±11.7; Padj=.003, and 31.7±9.0, 35.2±7.5, 38.2±9.3; Padj=.001, respectively. CONCLUSIONS: Long-term childhood leukemia survivors showed a subtle impairment of diastolic function that was detected with atrial strain but not with conventional measurements. This impairment was more pronounced in those with higher exposure to cardiotoxic treatment.

BACKGROUND: Several orthotopic transcatheter strategies have been developed to treat severe tricuspid regurgitation (TR); however, many patients are deemed unsuitable. Caval valve implantation with the TricValve system addresses this unmet need. OBJECTIVES: This study sought to determine the impact of TricValve on systemic congestion and quality of life (QOL) at 1 year. METHODS: The TRICUS (Safety and Efficacy of the TricValve® Transcatheter Bicaval Valves System in the Superior and Inferior Vena Cava in Patients With Severe Tricuspid Regurgitation) and TRICUS EURO studies were prospective, nonblinded, nonrandomized, single-arm trials representing the early-in-man experience of the TricValve system in NYHA functional class III or IV severe TR patients, optimally medicated and ineligible for open heart surgery, with significant caval backflow. The primary endpoint was QOL metrics and functional status. The 1-year results of the combined cohort are described here. RESULTS: Forty-four patients were included. Mean age was 76.2 ± 7.5 years, 81.0% were women, and the TRISCORE (risk score model for isolated tricuspid valve surgery) was 5.3 ± 1.3. Clinical improvement at 1 year was achieved in 42 (95.5%) patients, measured by (at least 1 of) an increase in ≥15 points from baseline in 12-item Kansas City Cardiomyopathy Questionnaire score, improvement to NYHA functional class to I or II, or an increase ≥40 m in the 6-minute walk test. There were 3 (6.8%) deaths at 1-year follow-up (1 cardiovascular), and the heart failure rehospitalization rate was 29.5%. Stent fracture, conduction system disturbances, or clinically significant leaflet thrombosis were not detected. Abolished hepatic vein backflow was achieved and persisted in 63.8% of the patients, contributing towards a reduction in congestive symptoms, N-terminal pro-B-type natriuretic peptide levels (P = 0.032), and diuretic treatment. CONCLUSIONS: Caval valve implantation with the TricValve system associated with meaningful 1-year clinical improvements in terms of QOL along with relatively low mortality rates.

INTRODUCTION AND OBJECTIVES: Stent implantation is the preferred treatment in older children and adults with aortic coarctation (CoA). We aimed to determine the incidence of very late events after CoA stenting. METHODS: We analyzed a cohort of CoA patients who underwent stent implantation at our center between 1993 and 2018. Patients were periodically followed up in outpatient clinics, including computed tomography (CT) and fluoroscopy assessment. RESULTS: A total of 167 patients with CT and fluoroscopy data were included: 83 (49.7%) were aged ≤ 12 years and 46 (28%) were female. The mean clinical follow-up time was 17±8 (range 4-30) years and the mean time to CT/fluoroscopy was 11±7 years. Aortic aneurysm was present in 13% and was associated with the PALMAZ stent (OR, 3.09; 95%CI, 1.11-9.49; P=.036) and the stented length (OR, 0.94; 95%CI, 0.89-0.99; P=.039). Stent fracture was frequent (34%), but was not related to the presence of aneurysm. Stent fracture was associated with young age (OR, 3.57; 95%CI, 1.54-8.33; P=.003), male sex (OR, 4.00; 95%CI, 1.51-12.5, P=.008) and inversely with the PALMAZ stent (OR, 0.29; 95%CI, 0.12-0.67, P=.005). Reintervention was lower in adults (10%), mainly related to aneurysms. Those treated when aged ≤ 12 years had higher reintervention rates (43%) due to recoarctation somatic growth. CONCLUSIONS: This long-term follow-up study of CoA patients treated with stenting revealed a significant incidence of late events. Reintervention rates were higher in patients treated at younger ages. Periodic imaging surveillance appears to be advisable.

BACKGROUND: The Amplatzer™ Trevisio™ Intravascular Delivery System (Trevisio DS; Abbott Laboratories, Chicago, IL, USA) facilitates the delivery of Amplatzer™ Occluders and features an ultraflexible tip, which improves assessment of occluder position before release. AIMS: To assess the safety and efficacy of the Trevisio DS for transcatheter closure of patent foramen ovale and atrial septal defect. METHODS: The Amplatzer™ Trevisio™ Intravascular Delivery System Post-Approval Study was a prospective, postmarket, single-arm, multicentre, observational study of the Trevisio DS. Enrolled patients were indicated for transcatheter closure of patent foramen ovale or atrial septal defect. In all procedures, the Trevisio DS was used to deliver Amplatzer™ Occluders. Technical success was defined as successful deployment and release of at least one occluder. Device- or procedure-related serious adverse events were tracked until discharge or day 7, whichever occurred earlier. RESULTS: The study enrolled 144 patients with patent foramen ovale and 107 patients with atrial septal defect at 22 European sites; 53 patients with atrial septal defect (49.6%) were aged<18years. The rate of technical success was 98.4% (97.2% for atrial septal defect, 99.3% for patent foramen ovale). There was one serious adverse event (0.4%), an acute periprocedural device embolization that occurred after occluder release in a patient with atrial septal defect; the device was retrieved percutaneously. This was determined by the implanter to be unrelated to the performance of the Trevisio DS. CONCLUSIONS: The Trevisio DS exhibited a high rate of technical success and an excellent safety profile during transcatheter closure of patent foramen ovale and atrial septal defect.

BACKGROUND: The multicentre European Bifurcation Club Trial (EBC TWO) showed no significant differences in 12-month clinical outcomes between patients randomised to a provisional stenting strategy or systematic culotte stenting in non-left main true bifurcations. AIMS: This study aimed to investigate the 5-year clinical results of the EBC TWO Trial. METHODS: A total of 200 patients undergoing stent implantation for non-left main bifurcation lesions were recruited into EBC TWO. Inclusion criteria required a side branch diameter ≥2.5 mm and side branch lesion length >5 mm. Five-year follow-up was completed for 197 patients. The primary endpoint was the composite of all-cause mortality, myocardial infarction, or target vessel revascularisation. RESULTS: The mean side branch stent diameter was 2.7±0.3 mm and mean side branch lesion length was 10.3±7.2 mm. At 5-year follow-up, the primary endpoint occurred in 18.4% of provisional and 23.7% of systematic culotte patients (hazard ratio [HR] 0.75, 95% confidence interval [CI]: 0.41-1.38). No significant differences were identified individually for all-cause mortality (7.8% vs 7.2%, HR 1.11, 95% CI: 0.40-3.05), myocardial infarction (8.7% vs 13.4%, HR 0.64, 95% CI: 0.27-1.50) or target vessel revascularisation (6.8% vs 9.3%, HR 1.12, 95% CI: 0.37-3.34). Stent thrombosis rates were also similar (1.9% vs 3.1%, HR 0.63, 95% CI: 0.11-3.75). There was no significant interaction between the extent of side branch disease and the primary outcome (p=0.34). CONCLUSIONS: In large non-left main true bifurcation lesions, the use of a systematic culotte strategy showed no benefit over provisional stenting for the composite outcome of all-cause mortality, myocardial infarction, or target vessel revascularisation at 5 years. The stepwise provisional approach may be considered preferable for the majority of true coronary bifurcation lesions. CLINICALTRIALS: gov: NCT01560455.
RESUMEN
There are limited data regarding right ventricle (RV) impairment in long-term survivors of childhood acute lymphoblastic leukemia (CLS). The aim of this study was to assess RV function in these patients using echocardiographic conventional measurements and automated RV strain. Echocardiographic recordings of 90 CLS and 58 healthy siblings from the CTOXALL cohort were analyzed. For group comparisons, inverse probability weighting was used to reduce confounding. The CLS group (24.6 ± 9.7 years, 37.8% women) underwent an echocardiographic evaluation 18 (11-26) years after the diagnosis. RV systolic dysfunction was found in 16.7% of CLS individuals using RV free-wall strain (RVFWS) compared to 2.2 to 4.4% with conventional measurements. RV systolic function measurements were lower in the CLS than in the control group: TAPSE (23.3 ± 4.0 vs. 25.2 ± 3.4, p = 0.004) and RVFWS (24.9 ± 4.6 vs. 26.8 ± 4.7, p = 0.032). Modifiable cardiovascular risk factors such as obesity (p = 0.022) and smoking (p = 0.028) were independently associated with reduced RVFWS. In conclusion, RV systolic function impairment was frequent in long-term survivors of childhood leukemia, underscoring the importance of RV assessment, including RVFWS, in the cardiac surveillance of these patients.
RESUMEN
Knowledge in the field of bifurcation lesions and chronic total occlusions (CTOs) has progressively improved over the past 20 years. Therefore, the European Bifurcation Club and the EuroCTO Club have decided to write a joint consensus statement to share general knowledge and practical approaches in this complex field. When percutaneously treating CTOs, bifurcation lesions with relevant side branches (SBs) are found in approximately one-third of cases (35% at the proximal cap, 38% at the distal cap, and 27% within the CTO body). Occlusion of a relevant SB is not rare and has been shown to be associated with procedural complications and adverse outcomes. Simple bifurcation rules are very useful to prevent SB occlusion, and provisional SB stenting is the recommended approach in the majority of cases: protect the SB as soon as possible by wiring it, respect the fractal anatomy of the bifurcation by using the 3-diameter rule, and avoid using dissection and re-entry techniques. A systematic 2-stent approach can be used if needed or sometimes to connect both branches of the bifurcation. The retrograde approach can be very useful to save a relevant SB, especially in the case of a bifurcation at the distal cap or within the CTO body. Intravascular ultrasound is also a very important tool to address the difficulties with bifurcations at the proximal or distal cap and sometimes also within the CTO segment. Double-lumen microcatheters and angulated microcatheters are crucial tools to resolve access difficulties to the SB or the main branch.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) in non-calcified aortic regurgitation (NCAR) is an off-label procedure. The balloon-expandable Myval includes extra-large sizes (30.5 mm and 32 mm) of interest in this setting. AIMS: We aimed to evaluate the safety and feasibility of Myval in NCAR. METHODS: This was an international, multicentre, observational study that enrolled all consecutive patients with symptomatic severe NCAR undergoing TAVR with the Myval device. The images were centrally analysed. RESULTS: A total of 113 patients were recruited, 64.6% were men, the mean age was 78.4±7.5 years, and the Society of Thoracic Surgeons score was 2.7±1.7%. Aortic root dilatation was present in 59.3% of patients, 7.1% were bicuspid, and the mean annular area was 638.6±106.0 mm2. The annular area was beyond the recommended range for extra-large sizes in 2.6% of cases, and additional volume was added in 92% (median 4 cc, up to 9 cc). The extra-large sizes were used in 95 patients (84.1%), and the mean oversizing was 17.9±11.0%. The technical success rate was 94.7%; the rate of residual ≥moderate aortic regurgitation was 8.9%, and the pacemaker rate was 22.2%. There were no cases of annular rupture, cardiac tamponade, or aortic dissection, but in 4 patients (3.5%) valve embolisation occurred (1 antegrade and 3 ventricular), all in cases with a tapered left ventricle outflow tract (p=0.007). Thirty-day and 1-year mortality were 5.3% and 9.7%, respectively. Technical success was associated with better survival (97.1% vs 72.7%; p=0.012), and valve embolisation was the main determinant of mortality (p=0.047). CONCLUSIONS: Myval is a feasible and safe option for selected non-operable patients with NCAR and demonstrated good midterm outcomes and lack of impact of oversizing on device durability.

BACKGROUND: The impact of intracoronary imaging on outcomes, after provisional versus dual-stenting for bifurcation left main (LM) lesions, is unknown. OBJECTIVES: We investigated the effect of intracoronary imaging in the EBC MAIN trial (European Bifurcation Club LM Coronary Stent study). METHODS: Four hundred and sixty-seven patients were randomized to dual-stenting or a stepwise provisional strategy. Four hundred and fifty-five patients were included. Intravascular ultrasound (IVUS) or optical coherence tomography (OCT) was undertaken at the operator's discretion. The primary endpoint was death, myocardial infarction or target vessel revascularization at 1-year. RESULTS: Intracoronary imaging was undertaken in 179 patients (39%; IVUS = 151, OCT = 28). As a result of IVUS findings, operators reintervened in 42 procedures. The primary outcome did not differ with intracoronary imaging versus angiographic-guidance (17% vs. 16%; odds ratio [OR]: 0.92 (95% confidence interval [CI]: 0.51-1.63) p = 0.767), nor for reintervention based on IVUS versus none (14% vs. 16%; OR: 0.88 [95% CI: 0.32-2.43] p = 0.803), adjusted for syntax score, lesion calcification and ischemic symptoms. With angiographic-guidance, primary outcome events were more frequent with dual versus provisional stenting (21% vs. 10%; adjusted OR: 2.11 [95% CI: 1.04-4.30] p = 0.039). With intracoronary imaging, there were numerically fewer primary outcome events with dual versus provisional stenting (13% vs. 21%; adjusted OR: 0.56 [95% CI: 0.22-1.46] p = 0.220). CONCLUSIONS: In EBC MAIN, the primary outcome did not differ with intracoronary imaging versus none. However, in patients with angiographic-guidance, outcomes were worse with a dual-stent than provisional strategy When intracoronary imaging was used, there was a trend toward better outcomes with the dual-stent than provisional strategy.

BACKGROUND: A small aortic annulus (SAA) is a risk factor for prosthesis-patient mismatch (PPM) in patients undergoing surgical or transcatheter aortic valve implantation (TAVI). Data regarding TAVI in patients with extra-SAA are scarce. AIMS: The aim of this study was to analyse the safety and efficacy of TAVI in patients with extra-SAA. METHODS: A multicentre registry study including patients with extra-SAA (defined as an aortic annulus area <280 mm2 and/or perimeter <60 mm) undergoing TAVI was established. Primary efficacy and safety endpoints were defined as device success and early safety at 30 days, respectively, using the Valve Academic Research Consortium-3 criteria, and were analysed according to valve type: self-expanding (SEV) versus balloon-expandable (BEV). RESULTS: A total of 150 patients were included, of which 139 (92.7%) were women, and 110 (73.3%) received an SEV. Intraprocedural technical success was 91.3%, with a higher rate in patients receiving an SEV (96.4% vs 77.5% with BEV; p=0.001). Overall, 30-day device success was 81.3%, (85.5% with SEV vs 70.0% with BEV; p=0.032). The primary safety endpoint occurred in 72.0% of patients (with no difference between groups; p=0.118). Severe PPM occurred in 12% (9.0% with SEV and 24.0% with BEV; p=0.039), with no impact on all-cause mortality, cardiovascular mortality, or heart failure readmission at 2-year follow-up. CONCLUSIONS: TAVI is a safe and feasible treatment in patients with extra-SAA with a high rate of technical success. The use of SEV was associated with a lower rate of intraprocedural complications, higher device success at 30 days and better haemodynamic outcomes compared to BEV.
