Long-Term Mortality in Patients With Severe Hypercholesterolemia Phenotype From a Racial and Ethnically Diverse US Cohort.

BACKGROUND: Tools for mortality prediction in patients with the severe hypercholesterolemia phenotype (low-density lipoprotein cholesterol ≥190 mg/dL) are limited and restricted to specific racial and ethnic cohorts. We sought to evaluate the predictors of long-term mortality in a large racially and ethnically diverse US patient cohort with low-density lipoprotein cholesterol ≥190 mg/dL. METHODS: We conducted a retrospective analysis of all patients with a low-density lipoprotein cholesterol ≥190 mg/dL seeking care at Montefiore from 2010 through 2020. Patients <18 years of age or with previous malignancy were excluded. The primary end point was all-cause mortality. Analyses were stratified by age, sex, and race and ethnicity. Patients were stratified by primary and secondary prevention. Cox regression analyses were used to adjust for demographic, clinical, and treatment variables. RESULTS: A total of 18 740 patients were included (37% non-Hispanic Black, 30% Hispanic, 12% non-Hispanic White, and 2% non-Hispanic Asian patients). The mean age was 53.9 years, and median follow-up was 5.2 years. Both high-density lipoprotein cholesterol and body mass index extremes were associated with higher mortality in univariate analyses. In adjusted models, higher low-density lipoprotein cholesterol and triglyceride levels were associated with an increased 9-year mortality risk (adjusted hazard ratio [HR], 1.08 [95% CI, 1.05-1.11] and 1.04 [95% CI, 1.02-1.06] per 20-mg/dL increase, respectively). Clinical factors associated with higher mortality included male sex (adjusted HR, 1.31 [95% CI, 1.08-1.58]), older age (adjusted HR, 1.19 per 5-year increase [95% CI, 1.15-1.23]), hypertension (adjusted HR, 2.01 [95% CI, 1.57-2.57]), chronic kidney disease (adjusted HR, 1.68 [95% CI, 1.36-2.09]), diabetes (adjusted HR, 1.79 [95% CI, 1.50-2.15]), heart failure (adjusted HR, 1.51 [95% CI, 1.16-1.95]), myocardial infarction (adjusted HR, 1.41 [95% CI, 1.05-1.90]), and body mass index <20 kg/m2 (adjusted HR, 3.36 [95% CI, 2.29-4.93]). A significant survival benefit was conferred by lipid-lowering therapy (adjusted HR, 0.57 [95% CI, 0.42-0.77]). In the primary prevention group, high-density lipoprotein cholesterol <40 mg/dL was independently associated with higher mortality (adjusted HR, 1.49 [95% CI, 1.06-2.09]). Temporal trend analyses showed a reduction in statin use over time (P<0.001). In the most recent time period (2019-2020), 56% of patients on primary prevention and 85% of those on secondary prevention were on statin therapy. CONCLUSIONS: In a large, diverse cohort of US patients with the severe hypercholesterolemia phenotype, we identified several patient characteristics associated with increased 9-year all-cause mortality and observed a decrease in statin use over time, in particular for primary prevention. Our results support efforts geared toward early recognition and consistent treatment for patients with severe hypercholesterolemia.

Echocardiographic and clinical features of patients developing prosthesis-patient mismatch after TAVR: insights from the Recovery TAVR registry.

BACKGROUND: The impact of prosthesis-patient mismatch (PPM) on major endpoints after transcatheter aortic valve replacement (TAVR) is controversial and the effects on progression of heart damage are poorly investigated. Therefore, our study aims to evaluate the prevalence and predictors of PPM in a "real world" cohort of patients at intermediate and low surgical risk, its impact on mortality and the clinical-echocardiographic progression of heart damage. METHODS: 963 patients who underwent TAVR procedure between 2017 and 2021, from the RECOVERY-TAVR international multicenter observational registry, were included in this analysis. Multiparametric echocardiographic data of these patients were analyzed at 1-year follow-up (FU). Clinical and echocardiographic features were stratified by presence of PPM and PPM severity, as per the most current international recommendations, using VARC-3 criteria. RESULTS: 18% of patients developed post-TAVR. PPM, and 7.7% of the whole cohort had severe PPM. At baseline, 50.3% of patients with PPM were male (vs 46.2% in the cohort without PPM, p=0.33), aged 82 (IQR 79-85y) years vs 82 (IQR 78-86 p=0.46), and 55.6% had Balloon-Expandable valves implanted (vs 46.8% of patients without PPM, p=0.04); they had smaller left ventricular outflow tract (LVOT) diameter (20 mm, IQR 19-21 vs 20 mm, IQR 20-22, p=0.02), reduced SVi (34.2 vs 38 ml/m2, p<0.01) and transaortic flow rate (190.6 vs 211 ml/s, p<0.01). At pre-discharge FU patients with PPM had more paravalvular aortic regurgitation (moderate-severe AR 15.8% vs 9.2%, p<0.01). At 1-year FU, maladaptive alterations of left ventricular parameters were found in patients with PPM, with a significant increase in end-systolic diameter (33 mm vs 28 mm, p=0.03) and a significant increase in left ventricle end systolic indexed volume in those with moderate and severe PPM (52 IQR 42-64 and 52, IQR 41-64 vs.44 IQR 35-59 in those without, p=0.02)). No evidence of a significant impact of PPM on overall (p=0.71) and CV (p=0.70) mortality was observed. Patients with moderate/severe PPM had worse NYHA functional class at 1 year (NYHA III-IV 13% vs 7.8%, p=0.03). Prosthesis size≤23 mm (OR 11.6, 1.68-80.1) was an independent predictor of PPM, while SVi (OR 0.87, 0.83-0.91, p<0.001) and LVOT diameter (OR 0.79, 0.65-0.95, p=0.01) had protective effect. CONCLUSIONS: PPM was observed in 18% of patients undergoing TAVR. Echocardiographic evaluations demonstrated a PPM-related pattern of early ventricular maladaptive alterations, possibly precursor to a reduction in cardiac function, associated with a significant deterioration in NYHA class at 1 year. These findings emphasize the importance of prevention of PPM of any grade in patients undergoing TAVR procedure, especially in populations at risk.

Routine postdilation after 23 mm Sapien 3 Ultra implantation in the aortic position.

BACKGROUND: Residual transprosthetic gradient (TG) after transcatheter aortic valve replacement (TAVR) with balloon-expandable valves (BEV) may be due to suboptimal valve expansion. AIMS: To compare hemodynamics after TAVR with small BEV according to postdilation strategy. METHODS: This observational, retrospective cohort study included 184 consecutive patients from a single center treated with 23 mm Sapien 3 Ultra (Edwards Lifesciences) BEV implantation in the aortic position and enrolled between January 2020 and April 2023. Patients treated with routine postdilation (RP, n = 73) were compared to patients treated according to local standard practice (SP, n = 111). Primary endpoint was 30-day mean TG. Secondary endpoints were incidence of 30-day prosthesis-patient mismatch (PPM), technical success and device success. RESULTS: Thirty-day mean TG was lower in RP versus SP (12.3 ± 4.6 mmHg vs. 14.1 ± 5.7 mmHg, p = 0.031), and incidence of PPM was less common with RP versus SP (47.3% vs. 71.0%, p = 0.006). Technical success (98.6% vs. 99.1%, p = 0.637) and device success (93.1% vs. 90.1%, p = 0.330) did not differ between groups. Differences in 30-day mean TG were driven by patients at normal flow (12.1 ± 4.0 mmHg vs. 15.0 ± 5.5 mmHg, p = 0.014), while no differences were evident among patients at low flow (12.5 ± 5.5 mmHg vs. 11.7 ± 5.5 mmHg, p = 0.644). RP decreased height and increased width of BEV, and a linear regression established that final BEV width could predict 30-day mean TG (r = -0.6654, p < 0.0001). CONCLUSIONS: RP after TAVR with small BEV was associated with more favorable forward-flow hemodynamics than SP.

Retrograde balloon hemostasis.

Despite improvements in current devices and techniques for complex chronic total occlusion (CTO) percutaneous coronary intervention (PCI), procedural complications, including coronary perforation, still occur and could be life-threatening. A patient with a history of multivessel coronary artery disease and a CTO of the right coronary artery (RCA) underwent successful retrograde crossing of an RCA CTO. After wiring the CTO body and lesion dilatation, a drug-eluting stent was implanted in the distal RCA toward the posterior descending artery. A large Ellis type III perforation occurred at the distal edge of the stent. Septal crossing with a balloon and tamponade of the perforation site through the retrograde collaterals followed, as the RCA was not suitable to accommodate easily both the covered stent and the balloon simultaneously. This case report presents a novel approach the "septal retrograde ping-pong" technique, which demonstrates successful treatment of coronary perforations by utilizing a retrograde approach through a septal collateral. This technique proves to be effective in situations where the conventional antegrade balloon or covered stent delivery methods are not feasible or unsuccessful. This innovative approach offers a promising alternative for managing challenging cases of coronary perforations, providing new insights and potential solutions for interventional cardiologists.

Randomized clinical trial of abluminus DES+ sirolimus-eluting stent versus everolimus-eluting DES for percutaneous coronary intervention in patients with diabetes mellitus: An optical coherence tomography study.

BACKGROUND: Diabetic patients are at higher risk of recurrent adverse events following percutaneous coronary intervention (PCI) than the nondiabetics. Despite the introduction of new generation drug-eluting stents, their efficacy in the diabetics is still limited. AIMS: To evaluate the efficacy of the Abluminus DES+ biodegradable polymer sirolimus-eluting stent in reducing neointimal hyperplasia in diabetic patients, compared to a durable polymer everolimus-eluting stent (DP-EES). METHODS: A total of 131 patients with diabetes and coronary artery disease were enrolled in six Italian centers and randomized in a 2:1 fashion to PCI with Abluminus DES+ or DP-EES: 85 were assigned to Abluminus DES+ and 46 to DP-EES. The primary endpoint was optimal coherence tomography (OCT)-derived neointimal volume at 9-12 months. Secondary endpoints included OCT-derived neointimal area, neointimal volume obstruction and adverse clinical events. RESULTS: The primary endpoint, neointimal volume, did not differ between Abluminus DES+ and DP-EES (29.11 ± 18.90 mm3 vs. 25.48 ± 17.04 mm3 , p = 0.40) at 9-12-month follow-up. This finding remained consistent after weighing for the sum of stents lengths (1.14 ± 0.68 mm3 vs. 0.99 ± 0.74 mm3 for Abluminus DES+ and DP-EES, respectively, p = 0.38). Similarly, other OCT-derived and clinical secondary endpoints did not significantly differ between the two groups. Rate of target lesion failure was high in both groups (21.2% for Abluminus DES+ and 19.6% for DP-EES). CONCLUSIONS: This preliminary study failed to demonstrate the superiority of the Abluminus DES+ over the DP-EES in diabetic patients in terms of neointimal proliferation.

Safety and efficacy of an ultra low dose fluoroscopic protocol for chronic total occlusion recanalization.

BACKGROUND: Chronic total occlusion (CTO) revascularization is a major source of radiation for both patients and physicians. Therefore, efforts to minimize radiation during CTO percutaneous coronary intervention (PCI) are highly encouraged. AIMS: To evaluate the impact of an Ultra Low fluoroscopic Dose Protocol (ULDP), based on 3.75 frames per second for the fluoroscopy and 7.5 frames per second for the cine acquisition, during CTO PCI. METHODS: One hundred fifty consecutive patients who underwent CTO PCI were retrospectively enrolled. Eighty-five underwent standard dose protocol (SDP) and 65 ULDP. Radiation exposure and acute clinical outcomes were compared between groups. Results were stratified according to lesion complexity. RESULTS: Patients undergoing ULDP, as compared to those undergoing SDP, showed a significant reduction of kerma area product, both for simple lesions (6861.0 vs. 13236.0 mGy × cm2 ; p = 0.014) and complex lesions (CL) (8865.0 vs. 16618.0 mGy × cm2 ; p < 0.001). Similarly, Air Kerma (AK) was lower when ULDP was used (1222.5 vs. 2015.0 cGy in SL, p = 0.134; 1499.0 vs. 2794.0 cGy in CL, p < 0.001). No significant differences were reported regarding procedural success and in-hospital major adverse cardiovascular events between groups. Notably, there was not any crossover from ULDO to SDP due to poor quality images. Interestingly, fluoroscopy time, procedural time and contrast volume was significantly lower in patients undergoing ULDP only for CLs. CONCLUSIONS: ULDP significantly reduces radiation exposure in the setting of high complexity procedures such as CTO PCI. This reduction seemed to be greater with increased procedural complexity and did not impact acute success or adverse clinical events.

Prosthesis-patient mismatch after transcatheter implantation of contemporary balloon-expandable and self-expandable valves in small aortic annuli.

BACKGROUND: Evidence of clinical impact of PPM after TAVI is conflicting and might vary according to the type of valve implanted. AIMS: To assess the clinical impact of prosthesis-patient mismatch (PPM) after transcatheter aortic valve implantation (TAVI) with balloon-expandable (BEV) and self-expandable valves (SEV) in patients with small annuli. METHODS: TAVI-SMALL 2 enrolled 628 patients in an international retrospective registry, which included patients with severe aortic stenosis and small annuli (annular perimeter <72 mm or area <400 mm2 ) treated with transfemoral TAVI at 16 high-volume centers between 2011 and 2020. Analyses were performed comparing patients with less than moderate (n = 452), moderate (n = 138), and severe PPM (n = 38). Primary endpoint was incidence of all-cause mortality. Predictors of all-cause mortality and PPM were investigated. RESULTS: At a median follow-up of 380 days (interquartile range: 210-709 days), patients with severe PPM, but not moderate PPM, had an increased risk of all-cause mortality when compared with less than moderate PPM (log-rank p = 0.046). Severe PPM predicted all-cause mortality in patients with BEV (hazard ratio [HR]: 5.20, 95% confidence interval [CI]: 1.27-21.2) and intra-annular valves (IAVs, HR: 4.23, 95% CI: 1.28-14.02), and it did so with borderline significance in the overall population (HR: 2.89, 95% CI: 0.95-8.79). Supra-annular valve (SAV) implantation was the only predictor of severe PPM (odds ratio: 0.33, 95% CI: 0.13-0.83). CONCLUSIONS: Patients with small aortic annuli and severe PPM after TAVI have an increased risk of all-cause mortality at early term follow-up, especially after IAV or BEV implantation. TAVI with SAV protected from severe PPM.

Clinical and procedural outcomes of percutaneous coronary intervention for de novo lesions involving the ostial left circumflex coronary artery.

BACKGROUND: Percutaneous treatment for ostial left circumflex artery (LCx) lesions is known to be associated with suboptimal results. AIMS: The present study aims to assess the procedural and long-term clinical outcomes of percutaneous coronary intervention (PCI) for de novo ostial LCx lesions overall and according to the coronary revascularization strategy. METHODS: Consecutive patients undergoing PCI with second generation drug eluting stents or drug coated balloons for de novo ostial LCx lesions in three high-volume Italian centers between 2012 and 2021 were retrospectively evaluated. The primary endpoint was target-vessel revascularization (TVR) at 2 years. Secondary endpoints included major adverse cardiovascular and cerebrovascular events (MACCE), target lesion revascularization, myocardial infarction, stroke, all-cause death, and repeat revascularization. RESULTS: A total of 366 patients were included in the analysis with a median follow-up of 901 (IQR: 450-1728) days. 79.5% of the patients were male, 33.6% were diabetic, 49.7% had a previous PCI, and 23.1% a prior surgical revascularization. Very ostial LCx stenting was performed in 34.1%, crossover from left main to LCx in 17.3%, and a two-stent strategy in 48.6% of cases, respectively. In the overall population, the incidence of TVR at 2 years was 19.0% while MACCE rate was 25.7%. No major differences in clinical outcomes were found according to the stenting strategy. Use of intracoronary imaging was associated with fewer MACCE (HR: 0.47, 95% CI: 0.25-1.13, p = 0.01), while the diameter of the stent implanted in the ostial LCx was associated with less TVR (HR: 0.43, 95% CI: 0.25-0.75, p = 0.002). CONCLUSIONS: Percutaneous revascularization of the ostial LCx is associated with a high rate of TVR, regardless of the stenting strategy. Intracoronary imaging and proper stent sizing may reduce the failure rates.

SUOH 03 Guidewire for the Management of Coronary Artery Dissection: Insights from a Multicenter Registry.

Background: In the setting of coronary artery dissection, both spontaneous and iatrogenic, fixing the intimal tear, usually with stent implantation, can be extremely challenging if the distal wire position has been lost. Common complications are mainly related to the inadvertent subintimal tracking of the guidewire while attempting to gain the distal true lumen. Aims: To report the registry results of using the SUOH 0.3 guidewire for managing coronary artery dissection in a real-world multicenter setting. Methods: The study population in this retrospective, multicenter, international registry included 75 consecutive patients who underwent PCI and required an antegrade wiring of a dissected coronary artery. Results: Successful use of SUOH 0.3 was achieved in 69 (92%) patients. The use of a microcatheter was associated with a significantly higher rate of TIMI 3 flow at the end of the procedure (no microcatheter: n = 17, 81%; microcatheter: n = 52, 96.3%; p = 0.017). The first recanalization attempt was made with the SUOH 03 guidewire in 48 (64%) cases, and it was successful in 42 (87%). The overall PCI success rate was reported in 72 (96%) patients, with no significant differences among patients with different origins, mechanisms, and locations of dissection. Conclusions: In this setting, the SUOH 0.3 guidewire provides high procedural success without additional complex techniques.

Acute coronary complications in chronic total occlusion interventions.

Chronic total occlusion (CTO) interventions are among the most complex procedures within the panorama of percutaneous coronary intervention (PCI). Awareness of potential complications, adequate procedural planning in order to avoid them, and prompt recognition and management should any occur are at the cornerstone of a successful CTO programme. Complications can be acute or late after the procedure and can be cardiac or non-cardiac. Acute cardiac complications can occur directly at the coronary artery level or can have other strictly non-coronary manifestations, such as hypotension, myocardial infarction, arrhythmias, or tamponade. In this review, we focus on acute coronary complications of CTO PCI, in particular their causes, prevention, and management strategies.

Prognostic value of tricuspid regurgitation.

Tricuspid regurgitation (TR) has a considerable prevalence in the overall population, that further increases in selected categories of patients. Three morphologic types of TR prevail, namely primary, secondary and atrial TR, mostly, but not always, occurring in different subsets of patients. Recent evidences demonstrate a negative impact of TR on outcomes, irrespective of etiology and even when less than severe in grading. Unfortunately, current surgical standards are void of strong prospective evidence of positive impact on clinical outcomes. While on one hand recent advances in diagnosis and risk stratification of patients with TR are shedding light onto the population that may benefit from intervention and its appropriate timing, on the other hand the arrival on stage of percutaneous treatment options is widening even more the therapeutic options for such population. In this review we will address and discuss the available evidence on the prognostic impact of TR in different clinical contexts encountered in practice.

Long term follow-up after balloon expandable covered stents implantation for management of transcatheter aortic valve replacement related vascular access complications.

OBJECTIVES: To report the experience of a high-volume center with balloon-expandable (BE) stents implantation to manage vascular complications after transcatheter aortic valve replacement (TAVR). BACKGROUND: Despite increased operator experience and better devices, vascular complications after TAVR are still a major issue and covered stent implantation is often required. METHODS: We retrospectively collected baseline and procedural data about 78 consecutive patients who underwent BE stent implantation to manage a vascular complication after transfemoral TAVR. Primary endpoints were technical success, incidence of new-onset claudication and need for vascular interventions during long-term follow-up. Secondary endpoints included length of hospitalization, in-hospital and 30-day mortality, and major postoperative complications. RESULTS: BE stents implantation to manage vascular complications after TAVR was successfully performed in 96.2% of the cases, with bailout surgery required in two cases. One patient suffered in-hospital death. Predischarge Doppler Ultrasound revealed no cases of in-stent occlusion or fracture. At a median follow-up of 429 days (interquartile range, 89-994 days), no cases of symptomatic leg ischemia were reported and only one patient experienced new-onset claudication. CONCLUSIONS: Our experience showed good periprocedural and long-term results of BE covered stent implantation to manage vascular complication after TAVR. Their great radial outward force may guarantee effective hemostasis without necessarily being associated with stent deformation/fracture resulting in restenosis or further interventions. More research is needed to define the role of BE covered stents in this setting.

SHORT-TERM MODIFICATIONS OF ELLIPSOID ZONE IN BEST VITELLIFORM MACULAR DYSTROPHY.

PURPOSE: To assess ellipsoid zone (EZ) alterations in Best vitelliform macular dystrophy using spectral-domain optical coherence tomography. METHODS: Prospective, observational case series. Forty-three patients (43 eyes) underwent complete ophthalmological examination at baseline and at 24 months: best-corrected visual acuity (BCVA), biomicroscopy, fundus photography, and spectral-domain optical coherence tomography were performed. Acquisition protocol included 19-line raster scan. Alterations in EZ were marked on spectral-domain optical coherence tomography, and the area was manually calculated on a near-infrared reflectance image. Three patterns were identified: A (decrease >0.25 mm2), B (±0.25 mm2), and C (increase >0.25 mm2). Primary outcome was to describe different patterns of EZ alteration. Secondary outcomes included their correlation with BCVA and the description of a central optically preserved islet. RESULTS: At baseline, altered EZ was identified in 40 eyes. Worse BCVA significantly correlated with larger EZ alterations but not with lesion extension on fundus photograph. Only "pattern-C" eyes unveiled BCVA worsening at follow-up. Optically preserved islet was detected in 16 eyes (37%), disclosing significantly better vision; its disappearance at follow-up (n = 7; 44% of 16 eyes) correlated with a decrease in BCVA. CONCLUSION: The assessment of EZ status might represent a valuable functional marker in Best vitelliform macular dystrophy because stable alterations and the maintenance of a central optically preserved islet are associated with better visual acuity.

Anatomic and procedural associations of transcatheter heart valve displacement following Evolut R implantation.

OBJECTIVES: This study aimed to predict the displacement of self-expanding transcatheter heart valves (THV) during final deployment. BACKGROUND: Accurate device positioning during transcatheter aortic valve implantation (TAVI) is crucial for optimal results. METHODS: At our institution, 103 patients who underwent transfemoral TAVI with Evolut R were retrospectively identified. Multiple linear regression models were created, and a predictor equation was built to quantify the factors that may affect THV behavior. RESULTS: Multiple linear regression analysis for THV displacement on the left coronary cusp (LCC) identified the angle between the THV and the ascending aorta (ATA), predilation, and less operator experience as independent predictors of upward displacement, whereas estimated glomerular filtration rate (eGFR) was inversely related with THV behavior (95% confidence interval: 0.219 to 0.340, 0.447 to 2.092, 0.165 to 1.757, and -0.053 to -0.011, respectively). Predictors of THV displacement on the noncoronary cusp side could not be identified using this model. CONCLUSIONS: The ATA at the point of recapture, predilation, and less operator experience were independent predictors of upward displacement of THV on the LCC side. eGFR was an independent predictor of THV downward displacement on the LCC side. Of them, the ATA was the strongest predictor. Physicians may need to adjust this angle adequately before deployment to achieve the appropriate position.

Transcatheter Aortic Valve Replacement: Current Status and Future Indications.

In the past two decades, transcatheter aortic valve replacement (TAVR) has transformed the management of aortic stenosis and has become the standard of care regardless of surgical risk levels. Advances in transcatheter valve design across newer generations, improved imaging, greater operator expertise, and technical enhancements have collectively contributed to increased safety and a decline in procedural complications over this timeframe. The application of TAVR has progressively expanded to include younger patients with lower risks, who have longer life expectancies. This article offers an up-to-date review of the latest innovations in transcatheter delivery systems, devices, and its possible future indications.

Inflammatory risk and clinical outcomes according to polyvascular atherosclerotic disease status in patients undergoing PCI.

BACKGROUND: Individuals suffering from polyvascular atherosclerotic disease (PolyVD) face a higher likelihood of adverse cardiovascular events. Additionally, inflammation, assessed by high-sensitivity C-reactive protein (hsCRP), affects residual risk following percutaneous coronary intervention (PCI). We aimed to explore the interplay between PolyVD and hsCRP in terms of clinical outcomes after PCI. METHODS: Patients undergoing PCI for chronic coronary disease at a tertiary center between January 2012 and February 2020 were included for the current analysis. PolyVD was defined by additional history of cerebrovascular and/or peripheral artery disease. HsCRP levels were defined as elevated when the measured baseline concentration was > 3 mg/L. The primary outcome of interest was major adverse cardiovascular events (MACE), a composite of all-cause mortality, spontaneous MI, or target vessel revascularization. RESULTS: Overall, 10,359 participants were included in the current study, with 17.4% affected by PolyVD and 82.6% included in the non-PolyVD subgroup. Patients with PolyVD had higher hsCRP levels than those without. Among the PolyVD group, a larger proportion (33.6%) exhibited elevated hsCRP compared to the non-PolyVD group (24.7%). Patients with both PolyVD and elevated hsCRP levels had significantly higher adverse event rates than all other subgroups at 1-year follow-up. Furthermore, an independent association between elevated hsCRP and MACE was observed within the PolyVD population, while this was not the case for individuals without PolyVD. CONCLUSION: A residual risk of adverse outcomes after PCI linked to inflammation appears to be present among individuals with PolyVD. This could help define further target populations for anti-inflammatory treatment options.

Prosthesis Tailoring for Patients Undergoing Transcatheter Aortic Valve Implantation.

Transcatheter aortic valve implantation (TAVI) has risen over the past 20 years as a safe and effective alternative to surgical aortic valve replacement for treatment of severe aortic stenosis, and is now a well-established and recommended treatment option in suitable patients irrespective of predicted risk of mortality after surgery. Studies of numerous devices, either newly developed or reiterations of previous prostheses, have been accruing. We hereby review TAVI devices, with a focus on commercially available options, and aim to present a guide for prosthesis tailoring according to patient-related anatomical and clinical factors that may favor particular designs.

A technology evaluation of the Onyx Frontier drug-eluting stent.

INTRODUCTION: Onyx FrontierTM represents the latest iteration within the family of zotarolimus-eluting stents (ZES), designed for the treatment of coronary artery disease. Approval by the Food and Drug Administration was granted in May 2022, and Conformité Européenne marking followed in August 2022. AREAS COVERED: We hereby review the principal design features of Onyx Frontier, highlighting differences and similarities with other currently available drug-eluting stents. In addition, we focus on the refinements of this newest platform as compared with previous ZES versions, including the attributes yielding its exceptional crossing profile and deliverability. The clinical implications related to both its newest and inherited characteristics will be discussed. EXPERT OPINION: The nuances of the latest Onyx Frontier, together with the continuous refinement previously witnessed throughout the development of ZES, lead to a latest generation device ideal for a diverse spectrum of clinical and anatomical scenarios. In particular, its peculiarities will be of benefit in the settings often offered by a progressively aging population, such as high bleeding risk patients and complex coronary lesions.

Management of Volume Overload in Severe Atrial-Functional Tricuspid Regurgitation: Improved Feasibility of Transcatheter Edge-to-Edge Repair.

Patients with tricuspid regurgitation are often referred late in their disease course and present with volume overload, which is a detrimental factor leading to right-sided chamber dilatation and dysfunction. Treatment of volume overload can 1) improve patient functional status; 2) avoid repeated invasive examinations; and 3) establish eligibility for transcatheter tricuspid intervention. (Level of Difficulty: Intermediate.).
