ABSTRACT
Background: Personalized prognosis plays a vital role in deciding between percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in patients with three-vessel disease (3VD). The aim of this study is to compare the modality of revascularization chosen by the local heart team to that recommended by using individualized predictions of medium, and long-term all-cause mortality amongst patients with 3VD screened in the Multivessel TALENT trial. Methods: The SYNTAX score II (SS-II) and SS-2020 were evaluated in 200 consecutive patients by a core laboratory and compared to the decision of the "on site" heart team. Results: According to the SS-II, CABG was the recommended treatment in 51 patients (25.5%) however 34 (66.6%) of them received PCI. According to SS-2020 the predicted absolute risk differences (ARD) between PCI and CABG were significantly higher in patients receiving CABG compared to those treated by PCI for major adverse cardiovascular and cerebrovascular events, a composite of all-cause mortality, stroke or myocardial infarction at 5-years (8.8 ± 4.6% vs 6.0 ± 4.0%, p < 0.001) and all-cause mortality at 5- (5.2 ± 3.5% vs 3.7 ± 3.0%, p = 0.008) and 10-years (9.3 ± 4.8% vs 6.2 ± 4.2%, p < 0.001). Based on the novel threshold of equipoise (individual absolute risk differences [ARD] < 4.5%), 133 patients were eligible for PCI however 23 of them underwent CABG; conversely, amongst the 67 patients where CABG was recommendation (individual ARD > 4.5%), only 19 received it. Conclusions: Despite the robustness of the risk models proposed for screening, several deviations from the recommended mode of revascularization were observed by the core laboratory among the first 200 patients with 3VD screened in the Multivessel TALENT trial.

ABSTRACT
BACKGROUND: In the PREPARE-CALC trial, severely calcified lesion preparation with rotational atherectomy (RA) before biodegradable polymer sirolimus-eluting stent (SES) implantation demonstrated higher procedural success and comparable rates of acute lumen gain and late lumen loss compared to modified balloons (MB) (scoring/cutting). We aimed to analyze the 5-year outcomes of both lesion preparation strategies. METHODS: PREPARE-CALC randomly assigned 200 patients 1:1 to MB or RA, followed by SES implantation. The principal endpoint of the current analysis was target vessel failure (TVF) at 5 years. RESULTS: At 5 years, MB had comparable rates of TVF to RA (19% vs. 21%, HR 1.14, 95% CI 0.60-2.16, p = 0.687). Subgroup analysis showed a lesion length treatment interaction, favoring MB for short lesions and RA for long ones (p for interaction = 0.042). Target lesion revascularization (TLR) was significantly less common with RA (12 vs. 3%, HR 0.28, 95% CI 0.08-0.98, p = 0.048). In a multivariate analysis, RA was independently protective against TLR (adj. HR 0.17, 95% CI 0.04-0.78, p = 0.022), while ostial lesions were associated with higher TLR independent of treatment strategy (adj. HR 11.3, 95% CI 2.98-42.6, p < 0.001). CONCLUSION: In patients with severely calcified coronary lesions, using MB or RA for lesion preparation followed by biodegradable polymer SES implantation was associated with comparable rates of TVF at 5 years. However, a significant reduction of TLR was observed after RA. PREPARE-CALC is the first randomized trial showing potential clinical advantages of RA over MB during long-term follow-up.

INTRODUCTION: The expansion of transcatheter aortic valve implantation (TAVI) to low-risk and younger patients has increased the relevance of the long-term durability of transcatheter heart valves (THV). The present study aims to assess the 10-year durability, hemodynamic performance, and clinical outcomes after TAVI using the CoreValve system. METHODS: An analysis from a prospective registry with predefined clinical and echocardiographic follow-up included 302 patients who underwent TAVI with the CoreValve system between 2007 and 2015. Bioprosthetic valve failure (BVF) was defined as any bioprosthetic valve dysfunction-related death, re-intervention, or severe hemodynamic valve deterioration. RESULTS: At the time of TAVI, the mean age was 80.41 ± 7.01 years, and the Society of Thoracic Surgeons (STS) score was 6.13 ± 5.23%. At latest follow-up (median [IQR]: 5 [2-7] years), cumulative all-cause mortality rates at 3, 5, 7, and 10 years was 23.7%, 40%, 65.8%, and 89.8%, respectively. Mean aortic valve area and transvalvular gradient post-TAVI and at 5, 7, and 10 years were 1.94, 1.87, 1.69, and 1.98 cm2 (p = 0.236) and 8.3, 9.0, 8.2, and 10.1 mmHg (p = 0.796), respectively. Overall, 11 patients had BVF, of whom six had structural valve deterioration (SVD). The 10-year actual and actuarial freedom from BVF was 96.1% and 78.8%, and from SVD was 97.9% and 80.9%, respectively. Three patients developed significant non-SVD due to severe paravalvular leakage, and two patients were diagnosed with infective endocarditis. CONCLUSION: Using an early-generation self-expanding bioprosthesis, we documented durable hemodynamic performance and low rates of BVF and SVD up to 10 years after TAVI.
ABSTRACT
BACKGROUND: Severely calcified coronary bifurcations complicate percutaneous coronary interventions (PCI) and often necessitate dedicated lesion preparation. We compared the outcomes of single- versus two-stent techniques for treating heavily calcified true bifurcation lesions following rotational atherectomy (RA). METHODS: Among patients receiving RA for severely calcified true bifurcations at a single center, 59 were treated with a single stent, and another 59 received two stents. We analyzed in-hospital adverse outcomes and 1-year rates of the bifurcation-oriented composite endpoint (BOCE), defined as cardiac death, target bifurcation myocardial infarction (TB-MI), or target bifurcation revascularization (TBR). RESULTS: The single-stent arm was associated with more in-hospital adverse outcomes (adj. OR, 6.13; 95% CI, 1.34-28.0; p = 0.019), driven by higher peri-procedural MI rates (18.6% vs. 5.1%, p = 0.043) and more side branch compromise (13.6% vs. 0%, p = 0.006). After 1 year, both techniques had comparable 1-year BOCE (adj. HR, 0.38; 95% CI, 0.12-1.23; p = 0.106). We observed a significant interaction between the treatment technique and the presence of LM bifurcation (p interaction = 0.012), favoring single-stent technique in patients with non-LM bifurcations (HR 0.14, 95% CI 0.03-0.68; p = 0.015). Notably, the single-stent technique had lower rates of TBR (2% vs. 15%, p log-rank = 0.026) after 1 year. CONCLUSION: Patients with severely calcified true bifurcation lesions, treated with RA followed by a single stent implantation, had more in-hospital adverse outcomes compared to those treated with two stents. However, the superior outcomes of the two-stent technique did not translate into improved long-term results. In fact, the two-stent technique was even associated with higher rates of revascularization after 1 year.

BACKGROUND: The latest generation ultrathin Supraflex Cruz (Sahajanand Medical Technologies Limited, Surat, India) sirolimus-eluting stent (SES) has shown early healing properties and represents an attractive percutaneous coronary intervention (PCI) device in a high bleeding risk (HBR) population. The aim of this Cruz HBR registry was to assess safety and efficacy of the Supraflex Cruz SES in a large cohort of all-comer patients, of whom about one third were patients at HBR. METHODS: Patients undergoing PCI were enrolled in this prospective, multi-centre, open label registry and stratified into non-HBR and HBR groups. The primary endpoint was a device-oriented composite endpoint (DOCE), a composite of cardiovascular death, myocardial infarction not clearly attributable to a non-target vessel and clinically driven target lesion revascularization within 12 months after PCI. The predefined aims were to show non-inferiority of the non-HBR group to the Supraflex arm of the TALENT Trial, and of the HBR group to polymer-free biolimus-coated stent arm of LEADERS FREE Trial. RESULTS: A total of 1203 patients were enrolled across 26 European centers, including a significant proportion (38.7%; N.=466) of HBR patients. A total of 1745 lesions were treated in 1203 patients and 2235 stents were implanted. The DOCE occurred within the total cohort in 5.8% of patients with a significant difference between HBR patients and non-HBR patients (8.1% vs. 4.4%; P<0.001). All-cause mortality at 12 months was significantly (P<0.0001) different among HBR (9.0%) and non-HBR patients (1.7%), respectively. At 12 months, the overall incidence of definite and probable stent thrombosis was 1.0%. Major bleeding occurred in 5.9% patients of the HBR group. These results met the non-inferiority criteria with respect to the TALENT trial for the non-HBR group (P<0.0001), and the LEADERS FREE trial for the HBR group (P<0.0001). CONCLUSIONS: The Cruz HBR registry confirms that PCI with the Supraflex Cruz SES is associated with a favorable clinical outcome in an all-comer population, including complex patients with HBR.

BACKGROUND: Although the use of rotational atherectomy (RA) is off-label in the setting of ST-elevation myocardial infarction (STEMI), it can be the only option in severely calcified culprit lesions to achieve procedural success. We sought to investigate the safety and feasibility of RA during primary percutaneous coronary intervention (PPCI). METHODS: This was a retrospective observational study of patients who underwent RA during PPCI from 12 European centres. The main outcomes were procedural success (defined as successful stent implantation with final thrombolysis in myocardial infarction [TIMI] flow 3 and residual stenosis < 30%) and in-hospital mortality. A comparison of patients presenting with and without shock was performed. RESULTS: In 104 patients with RA during STEMI, the mean age was 72.8 ± 9.1 years, and 35% presented with cardiogenic shock. Bailout RA was performed in 76.9% of cases. Mean burr size was 1.42 ± 0.21 mm. Procedural success was achieved in 86.5% of cases, with no difference between shocked and nonshocked patients (94.4% vs 82.4%; P = 0.13). In-hospital stent thrombosis occurred in 0.96%, perforation in 1.9% and burr entrapment in 2.9% of cases. In spite of equally high procedural success, in-hospital mortality was higher in shocked (50%) compared with nonshocked patients (1.5%; P < 0.0001). CONCLUSIONS: Patients presenting with STEMI requiring RA, represent a high-risk population, frequently presenting with cardiogenic shock. In this analysis of selected patients, RA was performed as a bailout strategy in the majority, and, as such, RA seems to be feasible with a high procedural success rate. In the absence of cardiogenic shock, RA-facilitated PCI seems to be associated with low in-hospital mortality.
