RESUMEN
BACKGROUND: Coronary artery disease (CAD) is a leading cause of death in the elderly population. Data regarding percutaneous coronary interventions (PCIs) in nonagenarians are scarce, and differences in long term outcomes between generations remain unclear. We aimed to study the pattern and temporal trends of nonagenarians treated with PCI. MATERIALS AND METHODS: A total of 14,695 patients underwent PCI between 2009-2020. We identified 2,034 (13.8%) octogenarians (age 80-89), and 222 (1.5%) nonagenarians (age 90-99). Endpoints included mortality and major adverse cardiac events (MACE) at 1 year. MATERIALS AND METHODS: A total of 14,695 patients underwent PCI between 2009-2020. We identified 2,034 (13.8%) octogenarians (age 80-89), and 222 (1.5%) nonagenarians (age 90-99). Endpoints included mortality and major adverse cardiac events (MACE) at 1 year. RESULTS: The number of nonagenarians undergoing PCI has increased substantially during the study time period, from 89 patients in the earlier time period (2009-2014) to 133 patients in the later time period (2015-2020). At 1-year, nonagenarians had significantly higher rates of both death (24.3% vs. 14.9%, p<0.01), and MACE (30.6% vs. 22.0%, p<0.01), as compared to octogenarians. The cumulative survival rate was higher among octogenarians both in the early and late time period (p<0.01 and p=0.039, respectively). A significant reduction in nonagenarian MACE rates were observed during the study time period, resulting in a non-significant difference in MACE rates in the later time period between both groups. CONCLUSION: The number of nonagenarians who undergo PCI is on the rise. While their clinical outcomes are inferior as compared to younger age groups, improvement was noted in the late time period.

Chronic myeloid leukaemia (CML) management is complicated by treatment-emergent vascular adverse events seen with tyrosine kinase inhibitors (TKIs) such as nilotinib, dasatinib and ponatinib. Pleural effusion and pulmonary arterial hypertension (PAH) have been associated with dasatinib treatment. Endothelial dysfunction and impaired angiogenesis are hallmarks of PAH. In this study, we explored, at cellular and whole animal levels, the connection between dasatinib exposure and disruption of endothelial barrier integrity and function, leading to impaired angiogenesis. Understanding the mechanisms whereby dasatinib initiates PAH will provide opportunities for intervention and prevention of such adverse effects, and for future development of safer TKIs, thereby improving CML management.
RESUMEN
BACKGROUND AND AIMS: This trial sought to assess the safety and efficacy of ShortCut, the first dedicated leaflet modification device, prior to transcatheter aortic valve implantation (TAVI) in patients at risk for coronary artery obstruction. METHODS: This pivotal prospective study enrolled patients with failed bioprosthetic aortic valves scheduled to undergo TAVI and were at risk for coronary artery obstruction. The primary safety endpoint was procedure-related mortality or stroke at discharge or 7 days, and the primary efficacy endpoint was per-patient leaflet splitting success. Independent angiographic, echocardiographic, and computed tomography core laboratories assessed all images. Safety events were adjudicated by a clinical events committee and data safety monitoring board. RESULTS: Sixty eligible patients were treated (77.0 ± 9.6 years, 70% female, 96.7% failed surgical bioprosthetic valves, 63.3% single splitting and 36.7% dual splitting) at 22 clinical sites. Successful leaflet splitting was achieved in all (100%; 95% confidence interval [CI] 94-100.0%, p<0.001) patients. Procedure time, including imaging confirmation of leaflet splitting, was 30.6 ± 17.9 min. Freedom from the primary safety endpoint was achieved in 59 (98.3%; 95% CI [91.1-100%]) patients, with no mortality and one (1.7%) disabling stroke. At 30 days, freedom from coronary obstruction was 95% (95% CI 86.1-99.0%). Within 90 days, freedom from mortality was 95% (95% CI 86.1-99.0%]), without any cardiovascular deaths. CONCLUSIONS: Modification of failed bioprosthetic aortic valve leaflets using ShortCut was safe, achieved successful leaflet splitting in all patients, and was associated with favorable clinical outcomes in patients at risk for coronary obstruction undergoing TAVI.
RESUMEN
AIMS: We examined whether thickness of the basal muscular interventricular septum (IVS), as measured by pre-procedural computed tomography (CT), could be used to identify the risk of conduction disturbances following transcatheter aortic valve replacement (TAVR). The IVS is a pivotal region of the electrical conduction system of the heart where the atrioventricular conduction axis is located. METHODS AND RESULTS: Included were 78 patients with severe aortic stenosis who underwent CT imaging prior to TAVR. The thickness of muscular IVS was measured in the coronal view, in systolic phases, at 1, 2, 5, and 10â mm below the membranous septum (MS). The primary endpoint was a composite of conduction disturbance following TAVR. Conduction disturbances occurred in 24 out of 78 patients (30.8%). Those with conduction disturbances were significantly more likely to have a thinner IVS than those without conduction disturbances at every measured IVS level (2.98 ± 0.52â mm vs. 3.38 ± 0.52â mm, 4.10 ± 1.02â mm vs. 4.65 ± 0.78â mm, 6.11 ± 1.12â mm vs. 6.88 ± 1.03â mm, and 9.72 ± 1.95â mm vs. 10.70 ± 1.55â mm for 1, 2, 5 and 10â mm below MS, respectively, P < 0.05 for all). Multivariable logistic regression analysis showed that pre-procedural IVS thickness (<4â mm at 2â mm below the MS) was a significant independent predictor of post-procedural conduction disturbance (adjOR 7.387, 95% CI: 2.003-27.244, P = 0.003). CONCLUSION: Pre-procedural CT assessment of basal IVS thickness is a novel predictive marker for the risk of conduction disturbances following TAVR. The IVS thickness potentially acts as an anatomical barrier protecting the underlying conduction system from mechanical compression during TAVR.

BACKGROUND: The ACURATE neo2 transcatheter aortic valve was developed to improve paravalvular leak (PVL) rates while maintaining low rates of conduction disturbances and permanent pacemaker implantation (PPMI) seen with its predecessor. We aimed to compare conduction disturbances rates of transcatheter aortic valve replacement (TAVR) using ACURATE Neo2 with other commonly used valves. METHODS: A retrospective analysis of the Israeli TAVR registry between the years 2014-2023 was performed to compare conduction disturbances and PVL rates, and procedural outcomes, among patients treated with ACURATE neo2, Edwards Sapien 3 (S3), and Evolut PRO valves. Propensity score matching was performed to compare groups with similar characteristics. RESULTS: Following exclusion of patients with non-femoral access, unknown valve type, older-generation valves, and less commonly used valves or (n = 4387), our analysis included 3208 patients undergoing TAVR using ACURATE neo2, Edwards S3, and Evolut PRO valves. Propensity matched groups comprised 169 patients each. Rates of any conduction disturbances [left bundle branch block (LBBB), atrioventricular block, or PPMI] were lower in the ACURATE neo2 group compared to both other valves [15.8 %, S3-37.5 % (p < 0.001), Evolut PRO-27.5 % (p = 0.02)] as were LBBB rates [9.0 %, S3-31.3 % (p < 0.001); Evolut PRO-20.1 % (p = 0.01). Atrioventricular block and PPMI rates were lower without statistical significance, as were rates of above-moderate PVL. CONCLUSIONS: In this analysis, TAVR using ACURATE neo2 was associated with a lower composite rate of conduction disturbances in comparison to the Evolut PRO and Edwards S3 valves, mainly due to lower left bundle branch block rates, with non-significantly lower rates of PPMI and PVL.
RESUMEN
Rationale & Objective: Kidney function can be adversely affected by significant tricuspid regurgitation (TR) owing to effects on cardiac output and systemic venous congestion. However, the impact of significant TR on short- and long-term kidney function following a kidney transplant remains uncertain. Study Design: Retrospective observational cohort. Setting & Participants: Kidney transplant recipients from a single center between 2016 and 2019. Exposure: Significant TR, defined by at least moderate regurgitation, on echocardiogram before kidney transplantation. Outcomes: Primary end points included the estimated glomerular filtration rate (eGFR) at the following 3 time points: 2 weeks, 3 months, and 1 year after transplantation. Secondary end points included major adverse cardiac events including nonfatal myocardial infarction, all-cause mortality, and hospitalization owing to cardiovascular disease. Analytical Approach: Propensity score matching was performed in 1:3 ratio between patients treated with significant TR and controls, within a caliper 0.05 standard deviation of the propensity score, to analyze for the primary end point. Results: Among 557 kidney transplant recipients, 26 (5%) exhibited significant TR pretransplantation. According to propensity score matching analysis, with 1:3 ratio between 24 patients with significant TR and 72 controls, the presence of significant TR was associated with a lower eGFR posttransplantation. Specifically, the mean eGFR was 41.2 mL/min/1.73 m2 compared to 53.3 mL/min/1.73 m2 at 2 weeks (P < 0.01), 50.0 mL/min/1.73 m2 versus 60.3 mL/min/1.73 m2 at 3 months (P < 0.01), and 49.4 mL/min/1.73 m2 versus 61.2 mL/min/1.73 m2 at 1 year (P < 0.01). Delayed graft function was observed in 41.7% of the patients with significant TR compared to 12.5% of those without significant TR (P < 0.01). No patients with significant TR required dialysis after 1 year. 1-year major adverse cardiac events were nonsignificantly higher among patients with significant TR (20.8% vs 8.1%; P = 0.16). Limitations: Retrospective design and relatively small TR population. Conclusions: The presence of significant TR among kidney transplant recipients was associated with a lower eGFR at 2 weeks, 3 months, and 1 year following transplant, although all remained dialysis independent at 1 year.
Significant tricuspid regurgitation (TR) is associated with increased mortality rates and kidney failure, but its impact on kidney transplant recipients is poorly investigated. We examined how significant TR diagnosed pretransplantation affects kidney function within the first posttransplant year in a retrospective cohort study. Among 24 patients with significant TR, there was a consistent pattern of lower kidney function at 2 weeks, 3 months, and 1 year following transplantation, compared to 72 matched controls based on a propensity score. Results were statistically significant at all time points within the first year after transplant. These findings suggest that selected individuals with significant TR are able to undergo successful kidney transplantation, although with worse kidney function following transplantation.

BACKGROUND: Data on the likelihood of left ventricle (LV) recovery in patients with severe LV dysfunction and severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) and its prognostic value are limited. AIMS: We aimed to assess the likelihood of LV recovery following TAVI, examine its association with midterm mortality, and identify independent predictors of LV function. METHODS: In our multicentre registry of 17 TAVI centres in Western Europe and Israel, patients were stratified by baseline LV function (ejection fraction [EF] >/≤30%) and LV response: no LV recovery, LV recovery (EF increase ≥10%), and LV normalisation (EF ≥50% post-TAVI). RESULTS: Our analysis included 10,872 patients; baseline EF was ≤30% in 914 (8.4%) patients and >30% in 9,958 (91.6%) patients. The LV recovered in 544 (59.5%) patients, including 244 (26.7%) patients whose LV function normalised completely (EF >50%). Three-year mortality for patients without severe LV dysfunction at baseline was 29.4%. Compared to this, no LV recovery was associated with a significant increase in mortality (adjusted hazard ratio 1.32; p<0.001). Patients with similar LV function post-TAVI had similar rates of 3-year mortality, regardless of their baseline LV function. Three variables were associated with a higher likelihood of LV recovery following TAVI: no previous myocardial infarction (MI), estimated glomerular filtration rate >60 mL/min, and mean aortic valve gradient (mAVG) (expressed either as a continuous variable or as a binary variable using the standard low-flow, low-gradient aortic stenosis [AS] definition). CONCLUSIONS: LV recovery following TAVI and the extent of this recovery are major determinants of midterm mortality in patients with severe AS and severe LV dysfunction undergoing TAVI. Patients with no previous MI and those with an mAVG >40 mmHg show the best results following TAVI, which are at least equivalent to those for patients without severe LV dysfunction.

INTRODUCTION: Variations in the left atrial appendage (LAA) morphology are associated with different embolic risk in patients with atrial fibrillation (AF). Data are scarce regarding the association between LAA morphology and Embolic stroke of undetermined source (ESUS). PATIENTS AND METHODS: Using cardiac computed tomography (CCT) scans, LAA morphology was categorized as either chicken wing (CW), cactus, windsock, or cauliflower. Furthermore, we examined the presence of large secondary lobes arising from the main lobe, considering their existence as indicative of a complex LAA morphology. LAA morphologies were compared between ESUS (n = 134) and AF patients (n = 120); and between ESUS patients with (n = 24) and without (n = 110) subsequent AF diagnosis during long-term follow-up. RESULTS: ESUS patients had a significantly higher prevalence of cauliflower morphology compared to AF group (52% vs 34%, respectively, p = 0.01); however, no significant difference was found between the groups when categorizing LAA morphology to either CW or non-CW. ESUS patients had significantly higher prevalence of large secondary lobes compared with AF patients (50% vs 29%, respectively, p = 0.001). When comparing ESUS patients with and without AF diagnosis during follow-up (20-48 months of follow-up, median 31 months), there were no significant differences in the prevalence of the "classical" morphologies, but large secondary lobes were significantly more prevalent among those without subsequent AF diagnosis. CONCLUSION: ESUS patients have a high prevalence of complex LAA morphology, which might be associated with an increased risk for thrombus formation even in the absence of AF.
RESUMEN
OBJECTIVE: To evaluate the association between trimethylamine N-oxide (TMAO) and related metabolites with adverse cardiovascular events in a multiethnic urban primary prevention population. METHODS: We performed a case-control study of 361 participants of the Dallas Heart Study, including 88 participants with an incident atherosclerotic cardiovascular disease (ASCVD) event and 273 controls matched for age, sex, and body mass index without an ASCVD event during 12 years of follow-up (January 1, 2000, through December 31, 2015). Plasma levels of TMAO, choline, carnitine, betaine, and butyrobetaine were measured by mass spectrometry. The differential odds for incident ASCVD by metabolite levels between cases and controls were compared by a conditional logistic regression model adjusted for cardiovascular risk factors. RESULTS: Participants with incident ASCVD had higher levels of TMAO and related metabolites compared with those without ASCVD (P<.05 for all). Those with plasma TMAO concentrations in quartile 4 had a more than 2-fold higher odds of ASCVD compared with those in quartile 1 (odds ratio, 2.77 [95% CI, 1.05 to 7.7; P=.04] for hard ASCVD and 2.41 [95% CI, 1.049 to 5.709; P=.04]). Similar trends were seen with the related metabolites choline, betaine, carnitine, and butyrobetaine. CONCLUSION: Our results suggest that TMAO and related metabolites are independently associated with ASCVD events. Although further studies are needed, measurement of TMAO and related metabolites may have a role in ASCVD risk stratification for primary prevention.
RESUMEN
BACKGROUND: Management of cancer patients presenting with an acute coronary syndrome (ACS) may be challenging. In this study, we sought to examine whether and how a concomitant diagnosis of active cancer affects patients' management and outcomes following an event of ACS. METHODS: We used a retrospective cohort data analysis of patients from the Acute Coronary Syndrome Israeli Survey (ACSIS) carried out between the years 2016-2021 to compare patients with and without a concomitant diagnosis of active cancer. RESULTS: Of 4913 patients who presented with an ACS, 90 (1.8%) patients had a concomitant active cancer. Cancer patients were older, with a higher prevalence of hypertension and chronic renal failure. The rate of ST-elevation myocardial infarction (STEMI) was similar (40%) between both groups. Cancer patients were less likely to undergo coronary angiography during hospitalization; but once it was performed, the rate of percutaneous coronary intervention was similar. The presence of cancer during an ACS was associated with an increased short- and long-term mortality. In a multivariate analysis, the risk for 1-year mortality remained significantly higher in cancer patient (HR 2.72, 95% CI 1.74-4.24, p < 0.001), and was most prominent in patients presenting with STEMI (HR 5.00, 95% CI 2.40-10.39, p < 0.001). Short- and long-term death rates were also higher in cancer patients after a propensity score matching and adjustment for comorbidities other than cancer. CONCLUSION: Despite significant advances in oncologic and cardiac care, the presence of active cancer in patients with an ACS is still associated with significantly increased risk for 1-year mortality.
RESUMEN
BACKGROUND: Acute ischemic stroke remains a serious complication of transcatheter aortic valve replacement (TAVR). Cerebral embolic protection devices (CEPD) were developed to mitigate the risk of acute ischemic stroke complicating TAVR (AISCT). However, the existing body of evidence does not clearly support CEPD efficacy in AISCT prevention. OBJECTIVES: In a cohort of patients with AISCT, we aimed to compare the characteristics and outcomes of patients who have had unprotected TAVR (CEPD-) vs CEPD-protected TAVR (CEPD+). METHODS: Data were derived from an international multicenter registry focusing on AISCT. We included all patients who experienced ischemic stroke within 72 hours of TAVR. Stroke severity was assessed using the National Institutes of Health Stroke Scale (NIHSS). Primary outcomes were neurologic disability status according to the modified Rankin Score at 30 days, and 6-month all-cause death. Propensity score matched analysis was used to control for differences between groups. RESULTS: In 18,725 TAVR procedures, 416 AISCT (2.2%) within 72 hours were documented, of which 376 were in the CEPD- TAVR group and 40 in the CEPD+ TAVR group. Although the middle cerebral artery stroke rate was similar in both groups (29.7% CEPD- vs 33.3% CEPD+; P = 0.71), AISCT in the CEPD+ group was characterized by a lower rate of internal carotid artery occlusion (0% vs 4.7%) and higher rate of vertebrobasilar system strokes (15.4% vs 5.7%; P = 0.04). AISCT was severe (NIHSS ≥15) in 21.6% CEPD- and 23.3% CEPD+ AISCT (P = 0.20). Disabling stroke rates (modified Rankin Score >1 at 30 days) were 47.3% vs 42.5% (P = 0.62), and 6-month mortality was 31.3% vs 23.3% (P = 0.61), in the CEPD- and CEPD+ groups, respectively. In the propensity score matched cohort, disabling stroke rates were 56.5% vs 41.6% (P = 0.16), and 6-month mortality was 33% vs 19.5% (P = 0.35), in the CEPD- and CEPD+ groups, respectively. CONCLUSIONS: In a large cohort of patients with AISCT, the use of CEPD had little effect on stroke distribution, severity, and outcomes.

BACKGROUND: The optimal antiplatelet regimen after percutaneous coronary intervention (PCI) in patients with peripheral artery disease (PAD) is still debated. This analysis aimed to compare the effect of ticagrelor monotherapy versus ticagrelor plus aspirin in patients with PAD undergoing PCI. METHODS: In the TWILIGHT trial, patients at high ischemic or bleeding risk that underwent PCI were randomized after 3 months of dual antiplatelet therapy (DAPT) to aspirin or matching placebo in addition to open-label ticagrelor for 12 additional months. In this post-hoc analysis, patient cohorts were examined according to the presence or absence of PAD. The primary endpoint was Bleeding Academic Research Consortium (BARC) 2, 3, or 5 bleeding. The key secondary endpoint was a composite of all-cause death, myocardial infarction (MI), or stroke. Endpoints were assessed at 12 months after randomization. RESULTS: Among 7,119 patients, 489 (7%) had PAD and were older, more likely to have comorbidities, and multivessel disease. PAD patients had more bleeding or ischemic complications than no-PAD patients. Ticagrelor monotherapy compared to ticagrelor plus aspirin was associated with less BARC 2, 3, or 5 bleeding in PAD (4.6% vs 8.7%; HR 0.52; 95%CI 0.25-1.07) and no-PAD patients (4.0% vs 7.0%; HR 0.56; 95%CI 0.45-0.69; interaction P-value .830) and a similar risk of death, MI, or stroke in these 2 groups (interaction P-value .446). CONCLUSIONS: Despite their higher ischemic and bleeding risk, patients with PAD undergoing PCI derived a consistent benefit from ticagrelor monotherapy after 3 months of DAPT in terms of bleeding reduction without any relevant increase in ischemic events.

INTRODUCTION: End-stage renal disease is a major risk factor for cardiovascular morbidity and mortality, which can be partially eliminated by kidney transplantation. Systolic heart failure might be considered contraindication for kidney transplant, although some patients demonstrate myocardial recovery post-transplant. We aimed to identify and characterize the phenomenon of reverse myocardial remodeling in kidney transplanted patients. METHODS: The study is a retrospective cohort of patients undergoing kidney transplants between 2016 and 2019 (n = 604) at Rabin Medical Center. Patients were assessed according to availability of two echocardiographic examinations: pre- and post-kidney transplant. The change in estimated ejection fraction (EF) and possible predictors of myocardial recovery were examined. RESULTS: Data of 293 patients was available for the final analysis. Eighty-one (28%) patients had a LVEF improvement equal to or above 5%, whereas 36 (12%) patients had a LVEF improvement of 10% or more post-transplantation. Twenty-five patients (8.5%) had moderate or severe systolic heart failure with LVEF reduced to 40% or less at baseline. 13 of them (52%) had a LVEF improvement of ≥5%, and 10 patients (40%) had an improvement of ≥10% in their EF. Cox regression analyses identified female gender as the only independent variable associated with LVEF improvement of at least 10%. CONCLUSION: Renal transplantation might lead to improved LV systolic function in some patients.
