RESUMO

BACKGROUND: There is a lack of data on the clinical outcomes following the use of different strategies for lesion preparation prior to the use of drug-coated balloons (DCB). In this study, we have explored the clinical outcomes between different types of pre-dilatation balloons: semicompliant (SB), non-compliant (NB) and scoring balloons (ScB) used when preparing denovo lesions prior to the use of DCB. METHODS: We retrospectively evaluated all patients who underwent treatment with DCB for de-novo lesions between 2011-2019 at 4 high-volume European centres. The measured study endpoints were: cardiac-death, TV-MI, TLR and MACE. RESULTS: During the study period, 553 patients were treated with DCB for de-novo lesions, 327 with SB only, 172 with NB and 54 with ScB. There were some differences in the procedural characteristics between the 3 groups. Pre-dilatation balloons were significantly larger in the ScB and NB groups as compared to the SB (2.7 mm and 2.6 mm vs. 2.3 mm; p< 0.001). The reference vessel diameter was significantly larger in the NB group as compared to the ScB and SB (2.6 mm vs. 2.2 mm and 2.3 mm; p<0.001). During the median follow-up duration of 547-days, there were no differences in the hard-clinical end-points, however, TLR was significantly higher in the ScB as compared to SB and NB group (11% vs. 3.4% and 4.7%; p=0.02). CONCLUSIONS: The PREPARE study results do not suggest routine use of ScB prior to DCB in de novo lesions.

RESUMO

BACKGROUND: Coronary lesions predilatation with semi-compliant (SC) or non-compliant balloons (NC) may be insufficient to obtain an optimal stent expansion, which can lead to in-stent restenosis or thrombosis. Moreover, increasing evidence support an optimal lesion preparation is mandatory when drug coated balloons (DCB) are used. To this extent, more "aggressive tools" such as cutting/scoring balloons, atherectomy or lithothripsy may play an important role and improve outcomes. METHODS: We enrolled 78 consecutive patients from March 2020 to October 2020 with calcific/fibrotic or ostially-located lesions, which were prepared using scoring balloons, in addition to SC/NC balloons and other plaque modification strategies. The final treatment consisted in either stent or DCB usage. The primary end-point was the rate of clinically-driven target lesion revascularization. Secondary endpoints entailed the procedural success and the individual rates of major adverse cardiac events (MACE) at 12 months. RESULTS: Most of the patients had left main (LM) or ostial lesions, 65% of them being moderate/severely calcified, with further debulking strategies being required in 15 (19.2%) patients (rotational atherectomy, 3.8% or coronary intravascular lithotripsy, 15.3%). A high-rate of DCB usage was reported. Angiographic and procedural success was obtained in 77 and 76 patients, respectively. We encountered one vessel perforation, which was sealed with a covered stent, without consequence. During follow up, we observed only 6 MACE, 6 target lesion revascularizations (TLR) and 2 cardiovascular deaths. CONCLUSIONS: Among patients with high complexity and calcific lesions, an optimal lesion preparation using a dedicated scoring balloon was associated with low clinical events at mid-term follow-up and may be considered to improve immediate procedural success rate.

RESUMO

Aortic stenosis is a highly prevalent cardiac valvular disease in adult population and increases with age. After symptoms onset in severe aortic stenosis, the prognosis begins to decline; however, new studies demonstrate an increased risk of death in patients with moderate disease. Although majority of patients with severe aortic stenosis are treated electively with surgical or transcatheter aortic valve replacement, not all patients are candidates for the interventions. Balloon aortic valvuloplasty can be used successfully as a bridge to definitive treatment or as palliative therapy in patients who are not candidates for either procedure. In this paper, we discuss and justify the current indications and contraindications for balloon aortic valvuloplasty. Additionally, the step-by-step procedure technique and most frequent complications are described. Moreover, we present the safety and feasibility of balloon aortic valvuloplasty in 33 consecutive patients on a waiting list for transcatheter aortic valve replacement at 3 expert Italian centers during the first and second waves of COVID-19, when clinical priorities focused on hospitalized patients with pneumonia. The procedural success in this cohort of patients was achieved in 31 patients (94%). Out of the 33 patients enrolled, 15 underwent TAVR within 5 ± 2 months from the valvuloplasty, and at 6-month follow-up a total of 2 patients died for end-stage heart failure.

RESUMO

Over the last 15 years, the management of aortic valve disease has been changed by transcatheter aortic valve replacement, which has become the standard of care across the entire spectrum of surgical risk. As a result of continuous evolution of this technique, several next-generation transcatheter heart valves (THVs) have been developed to minimize procedural complications and improve patient outcomes. This review aims to provide an update on the new generation THVs and delivery systems.

RESUMO

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is an effective treatment option for patients with severe, symptomatic AS, regardless of the transcatheter heart valve (THV) implanted. Prior studies demonstrated a higher device success with lower paravalvular leak (PVL) using the balloon-expandable (BE) Sapien/XT THV vs. a self-expanding (SE) THV. However, few data are available on the performance of a novel BE THV. PURPOSE: to compare early clinical performance and safety of the newly available BE Myval THV (Myval, Meril Life Sciences Pvt. Ltd., India) vs. the commonly used SE (Evolut R, Medtronic) THV. METHODS:  A single-center, retrospective cohort analysis was performed with 166 consecutive patients undergoing TAVR from March 2019 to March 2021 for severe symptomatic AS treated with either the novel BE Myval or the SE Evolut R (ER) bioprosthesis. The primary endpoint was device success at day 30 according to the Valve Academic Research Consortium-3 (VARC-3). Secondary endpoints included 30-day all-cause mortality, cardiovascular mortality, more than mild PVL, permanent pacemaker implantation (PPI) rates and a composite of all-cause mortality and disabling stroke at 6 months. RESULTS:  Among the 166 included patients, 108 patients received the SE ER THV and 58 patients were treated with the BE Myval THV. At baseline, the two groups showed comparable demographic characteristics. The primary composite endpoint of early device success occurred in 55 patients (94.8%) in the BE Myval group and in 90 patients (83.3%) in the SE ER group (OR 3.667, 95% CI 1.094-12.14; p = 0.048). At day 30, the BE Myval THV group exhibited a significantly lower incidence of more than mild PVL (BE Myval 3.45% vs. SE ER 14.8%, OR 0.2, 95% CI 0.05-0.8; p = 0.0338), along with a lower rate of PPI (BE Myval 11% vs. SE ER 24.2%, OR 0.38, 95% CI 0.15-0.99; p = 0.0535). At the 6-month follow-up, the incidence of all-cause mortality and disabling stroke did not significantly differ between the two groups, while the incidence of PPI (BE Myval 11% vs. SE ER 27.5%, OR 0.32, CI 95% 0.1273-0.8; p = 0.02) and ≥moderate PVL (BE Myval 6.9% vs. SE ER 19.8%, OR 0.31, 95% CI 0.1-0.94; p = 0.0396) was significantly lower in the BE Myval group. CONCLUSIONS: In patients with severe symptomatic AS undergoing TAVR, the novel Myval BE THV provided a comparable performance to the well-known ER SE THV, and it was associated with a lower rate of PPI and ≥moderate PVL within 30 days and 6 months after the procedure. Randomized, head-to-head comparison trials are needed to confirm our results.

RESUMO

OBJECTIVES: This study evaluated the incidence, management, and outcome of patients who experienced MitraClip (Abbott Vascular) failure secondary to loss of leaflet insertion (LLI), single leaflet detachment (SLD), or embolization. BACKGROUND: Transcatheter edge-to-edge repair with MitraClip is an established therapy for the treatment of mitral regurgitation (MR), but no data exist regarding the prevalence and outcome according to the mode of clip failure. METHODS: Between January 2009 and December 2020, we retrospectively screened 4,294 procedures of MitraClip performed in 19 centers. LLI was defined as damage to the leaflet where the MitraClip was attached, SLD as demonstration of complete separation between the device and a single leaflet tissue, and clip embolization as loss of contact between MitraClip and both leaflets. RESULTS: A total of 147 cases of MitraClip failure were detected (overall incidence = 3.5%), and these were secondary to LLI or SLD in 47 (31.9%) and 99 (67.3%) cases, respectively, whereas in 1 (0.8%) case clip embolization was observed. MitraClip failure occurred in 67 (45.5%) patients with functional MR, in 64 (43.5%) patients with degenerative MR, and 16 (10.8%) with mixed etiology. Although the majority of MitraClip failures were detected before discharge (47 intraprocedural and 42 in the hospital), up to 39.5% of cases were diagnosed at follow-up. In total, 80 (54.4%) subjects underwent a redo procedure, either percutaneously with MitraClip (n = 51, 34.7%) or surgically (n = 36, 24.5%) including 4 cases of surgical conversion of the index procedure and 7 cases of bailout surgery after unsuccessful redo MitraClip. After a median follow-up of 163 days (IQR: 22-720 days), 50 (43.9%) subjects presented moderate to severe MR, and 43 (29.3%) patients died. An up-front redo MitraClip strategy was associated with a trend toward a reduced rate of death at follow-up vs surgical or conservative management (P = 0.067), whereas postprocedural acute kidney injury, age, and moderate to severe tricuspid regurgitation were independent predictors of death. CONCLUSIONS: MitraClip failure secondary to LLI and SLD is not a rare phenomenon and may occur during and also beyond hospitalization. Redo MitraClip strategy demonstrates a trend toward a reduced risk of death compared with bailout surgery and conservative management. A third of those patients remained with more than moderate MR and had substantial mortality at the intermediate-term follow-up.

RESUMO

Aortic valve-in-valve (ViV) procedure is a valid treatment option for patients affected by bioprosthetic heart valve (BHV) degeneration. However, ViV implantation is technically more challenging compared to native trans-catheter aortic valve replacement (TAVR). A deep knowledge of the mechanism and features of the failed BHV is pivotal to plan an adequate procedure. Multimodal imaging is fundamental in the diagnostic and pre-procedural phases. The main challenges associated with ViV TAVR consist of a higher risk of coronary obstruction, severe post-procedural patient-prosthesis mismatch, and a difficult coronary re-access. In this review, we describe the principles of ViV TAVR.

RESUMO

Bicuspid aortic valve (BAV) is the most common valvular congenital anomaly and is apparent in nearly 50% of candidates for AV replacement. While transcatheter aortic valve implantation (TAVI) is a recommended treatment for patients with symptomatic severe aortic stenosis (AS) at all surgical risk levels, experience with TAVI in severe bicuspid AS is limited. TAVI in BAV is still a challenge due to its association with multiple and complex anatomical considerations. A retrospective study has been conducted to investigate TAVI's procedural and 30-day outcomes using the Myval transcatheter heart valve (THV) (Meril Life Sciences Pvt. Ltd. Vapi, Gujarat, India) in patients with severe bicuspid AS. Data were collected on 68 patients with severe bicuspid AS who underwent TAVI with the Myval THV. Baseline characteristics, procedural, 30-day echocardiographic and clinical outcomes were collected. The mean age and STS PROM score were 72.6 ± 9.4 and 3.54 ± 2.1. Procedures were performed via the transfemoral route in 98.5%. Major vascular complications (1.5%) and life-threatening bleeding (1.5%) occurred infrequently. No patient had coronary obstruction, second valve implantation or conversion to surgery. On 30-day echocardiography, the mean transvalvular gradient and effective orifice area were 9.8 ± 4.5 mmHg and 1.8 ± 0.4 cm2, respectively. None/trace aortic regurgitation occurred in 76.5%, mild AR in 20.5% and moderate AR in 3%. The permanent pacemaker implantation rate was 8.5% and 30-day all-cause death occurred in 3.0% of cases. TAVI with the Myval THV in selected BAV anatomy is associated with favorable short-term hemodynamic and clinical outcomes.

RESUMO

OBJECTIVES: to test the safety and efficacy of intravascular imaging and specifically optical coherence tomography (OCT) as a diagnostic tool for left main angioplasty and analyze the mid-term outcome accordingly. BACKGROUND: Clinical data and international guidelines recommend the use of intravascular imaging ultrasound (IVUS) to guide left main (LM) angioplasty. Despite early experience using OCT in this setting is encouraging, the evidence supporting its use is still limited. METHODS: ROCK II is a multicenter, investigator-driven, retrospective European study to compare the performance of IVUS and OCT versus angiography in patients undergoing distal-LM stenting. The primary study endpoint was target-lesion failure (TLF) including cardiac death, target-vessel myocardial infarction and target-lesion revascularization. We designed this study hypothesizing the superiority of intravascular imaging over angiographic guidance alone, and the non-inferiority of OCT versus IVUS. RESULTS: A total of 730 patients, 377 with intravascular-imaging guidance (162 OCT, 215 IVUS) and 353 with angiographic guidance, were analyzed. The one-year rate of TLF was 21.2% with angiography and 12.7% with intravascular-imaging (p = 0.039), with no difference between OCT and IVUS (p = 0.26). Intravascular-imaging was predictor of freedom from TLF (HR 0.46; 95% CI 0.23-0.93: p = 0.03). Propensity-score matching identified three groups of 100 patients each with no significant differences in baseline characteristics. The one-year rate of TLF was 16% in the angiographic, 7% in the OCT and 6% in the IVUS group, respectively (p = 0.03 for IVUS or OCT vs. angiography). No between-group significant differences in the rate of individual components of TLF were found. CONCLUSIONS: Intravascular imaging was superior to angiography for distal LM stenting, with no difference between OCT and IVUS.

RESUMO

BACKGROUND: Transcatheter aortic valve replacement (TAVR) is safe and feasible in patients with bicuspid aortic valve (BAV), but whether annular size may influence TAVR results in BAV patients remains unclear. We aimed at evaluating the impact of aortic annular size on procedural and clinical outcomes of BAV patients undergoing TAVR, as well as potential interactions between annular dimension and trans-catheter heart valve (THV) type (balloon-expandable (BEV) vs. self-expanding (SEV). METHODS: BEAT is a multicenter registry of consecutive BAV stenosis undergoing TAVR. For this sub-study patients were classified according to annular dimension in small-annulus (area < 400 mm2 or perimeter <72 mm), medium-annulus (area ≥ 400 and < 575 mm2, perimeter ≥72 mm and< 85 mm), large-annulus (area ≥ 575 mm2 or perimeter ≥85 mm). Primary endpoint was Valve Academic Research Consortium-2 (VARC-2) device success. RESULTS: 45(15.5%) patients had small, 132(45.3%) medium, and 114(39.2%) large annuli. Compared with other groups, patients with large annuli were more frequently male, younger, with higher body mass index, larger aortic valve area, higher rate of moderate-severe calcification, lower mean trans-aortic valve gradient and lower left ventricular ejection fraction. In large-annuli SEVs were associated with a lower VARC-2 device success (75.9% vs. 90.6%, p = 0.049) driven by a higher rate of paravalvular valvular leak (PVL) compared to BEVs (20.7% vs. 1.2%, p < 0.001). However, no differences in clinical outcomes were observed according to annular size nor THV type. CONCLUSIONS: TAVR in BAV patients is feasible irrespective of annular size. However in patients with large aortic annulus SEVs were associated with a significantly higher rate of PVLs compared to BEVs.

RESUMO

BACKGROUND: The presence of severe calcific atherosclerosis at the iliofemoral axis may preclude transcatheter aortic valve implantation (TAVI) by the transfemoral (TF) approach. Intravascular lithotripsy (IVL) is a novel technology that fractures intimal/medial calcium and increases vessel compliance allowing TF TAVI in selected patients with peripheral artery disease (PAD). AIMS: The aim of this study was to report on the safety and efficacy of IVL-assisted TF TAVI in an all-comers population. METHODS: Clinical, imaging and procedural data on all consecutive patients treated by IVL-assisted TF TAVI in six high-volume European centres (2018-2020) were collected in this prospective, real-world, multicentre registry. RESULTS: IVL-assisted TF TAVI was performed in 108 patients, increasing from 2.4% to 6.5% of all TAVI from 2018 to 2020, respectively. The target lesion was most often localised at the common and/or external iliac artery (93.5% of cases; average TL-MLD 4.6±0.9 mm with 318 degrees of calcium arc). Transfemoral aortic valve delivery was successful in 100% of cases; final procedural success in 98.2% (two conversions to cardiac open surgery for annular rupture and valve migration). Complications of the IVL-treated segments consisted of 1 perforation and 3 major dissections requiring stent implantation (2 covered stents and 2 BMS). Access-site-related complications included 3 major bleedings. Three in-hospital deaths were recorded (2.8%, 1 failed surgical conversion after annular rupture, 1 cardiac arrest after initial valvuloplasty, 1 late hyperkalaemia in renal dysfunction). CONCLUSIONS: IVL-assisted TF TAVI proved to be a safe and effective approach, which helps to expand the indications for TF TAVI in patients with severe calcific PAD. However, these patients continue to have a higher-than-average incidence of periprocedural complications.

RESUMO

BACKGROUND: A polymer-free biolimus-eluting stent (PF-BES) and a zotarolimus-eluting stent (ZES) recently showed similar clinical profiles and appear to be competing options in specific clinical settings of patients undergoing percutaneous coronary intervention (PCI). Whether they perform similarly also in complex procedural settings as coronary bifurcation lesions remains unaddressed. METHODS: All consecutive patients undergoing coronary bifurcation PCI with PF-BES or the new iteration of the ZES from three large multicenter real-world registries were included. The primary outcome was major adverse cardiovascular events (MACE), a composite of all-cause death, myocardial infarction (MI), target lesion revascularization (TLR) and stent thrombosis (ST). Multiple analyses to adjust for baseline differences were carried out including propensity-score matching, propensity-score stratification and inverse-probability-weighting. Outcomes are reported according to Cox proportional hazard models censored at 400-day follow-up. RESULTS: 1169 patients treated with PF-BES (n = 440) or ZES (n = 729) on the main branch of a coronary bifurcation lesion were included (mean age 69 ± 11 years, 75.4% male, 53.8% acute coronary syndrome at presentation, 26.6% left main bifurcation, median dual antiplatelet therapy duration 12 [range 12-12] months). MACE, all-cause death, TLR and ST tended towards non-statistically higher rates with the PF-BES as compared to the ZES. Higher MI and target vessel revascularization occurrence was observed with PF-BES. CONCLUSIONS: In this large contemporary cohort of patients undergoing coronary bifurcation PCI, the occurrence of MACE was non-statistically different with the use of PF-BES and ZES devices. However, differences favoring the ZES device that may entail clinical relevance were observed. Further studies are needed to confirm these findings and explore whether they remain valid when a short dual antiplatelet therapy is adopted.

RESUMO

OBJECTIVES: The aim of this study is to assess the feasibility, efficacy and safety of the "RotaTripsy" approach in severe calcified coronary artery lesions. BACKGROUND: Coronary lesions with a high calcium content represent a challenging scenario in interventional cardiology, requiring a proper lesion preparation. In this light, very little is known about the possibility to combine the benefits of rotational atherectomy and intravascular lithotripsy. METHODS: We retrospectively enrolled 34 patients from a real-word, multicenter, cohort of patients affected by severe calcified coronary artery lesions, which required the "RotaTripsy" to obtain a proper lesion preparation. In all the cases, rotational atherectomy and then intravascular lithotripsy were performed as a bail-out strategy following sub-optimal non-compliant balloon expansion. In 53% of the cases, the procedure was guided by intracoronary imaging findings. RESULTS: Procedural success was reported in all the cases, without any in-hospital major complication. Few major adverse clinical events were reported at mid-term follow-up. CONCLUSIONS: "RotaTripsy" can represent a valid therapeutic option for undilatable heavily calcified coronary artery lesions. Our findings demonstrate the feasibility, safety and efficacy of this approach.

RESUMO

Coronary bifurcation lesion (CBL) is a common but challenging scenario in percutaneous coronary interventions. Drug-coated balloons (DCBs) are modern devices with attractive perspective in CBL treatment. In-stent restenosis, small vessel and diffuse de-novo coronary artery disease have been, so far, considered the ideal scenario for DCBs application. Studies assessing DCBs in de-novo CBL demonstrated the safety and efficacy of this strategy. However, the heterogeneity of the study populations and the presence of methodological limitations prevent from drawing definite recommendations. Considering that the best treatment of bifurcations has not yet been defined, the "leaving nothing behind" philosophy will be the topic of future studies.

RESUMO

Bioresorbable scaffolds provide transient vessel support without the long-term limitations of permanent metallic drug-eluting stents. The sirolimus-eluting resorbable magnesium scaffold Magmaris is the only CE-marked metallic bioresorbable scaffold and provides short-term lumen support before being completely bioresorbed. To date, clinical trial results have demonstrated low adverse event rates in patients with simple coronary lesions. Seven European centers with large experience in Magmaris implantation, combined efforts in an informal collaboration to evaluate and appraise clinical data currently available regarding the performance of Magmaris in patients presenting with acute coronary syndromes, and to supply user-advice on patient selection and optimal implantation practice.

RESUMO

BACKGROUND: Patients presenting with the coronavirus-2019 disease (COVID-19) may have a high risk of cardiovascular adverse events, including death from cardiovascular causes. The long-term cardiovascular outcomes of these patients are entirely unknown. We aim to perform a registry of patients who have undergone a diagnostic nasopharyngeal swab for SARS-CoV-2 and to determine their long-term cardiovascular outcomes. STUDY AND DESIGN: This is a multicenter, observational, retrospective registry to be conducted at 17 centers in Spain and Italy (ClinicalTrials.gov number: NCT04359927). Consecutive patients older than 18 years, who underwent a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV2 in the participating institutions, will be included since March 2020, to August 2020. Patients will be classified into two groups, according to the results of the RT-PCR: COVID-19 positive or negative. The primary outcome will be cardiovascular mortality at 1 year. The secondary outcomes will be acute myocardial infarction, stroke, heart failure hospitalization, pulmonary embolism, and serious cardiac arrhythmias, at 1 year. Outcomes will be compared between the two groups. Events will be adjudicated by an independent clinical event committee. CONCLUSION: The results of this registry will contribute to a better understanding of the long-term cardiovascular implications of the COVID19.
