Background: Transcatheter edge-to-edge repair (TEER) improved outcomes in patients with heart failure (HF) and severe secondary mitral regurgitation (SMR) compared with guideline-directed medical therapy (GDMT) alone regardless of the severity of baseline left ventricular ejection fraction (LVEF). The study aimed to evaluate the effect of early changes in LVEF after TEER and GDMT alone in patients with HF and severe SMR. Methods: Within the COAPT trial, we evaluated outcomes according to changes in LVEF from baseline to 30 days. The primary outcome was all-cause death or HF hospitalization (HFH) between 30 days and 2 years. Results: Among 432 patients with paired echocardiographic data, 182 (42.1%) had increased LVEF (LVEF change 6.0% ± 4.9%) and 250 (57.9%) had a decrease or no change in LVEF (LVEF change -6.6% ± 5.6%) from baseline to 30 days. LVEF at 30 days increased more frequently with GDMT alone compared with TEER plus GDMT (51.4% vs 33.0%; P = .0001). Between 30 days and 2 years, there were no significant differences in death or HFH in the increase LVEF and the decrease LVEF groups (58.8% vs 51.4%; multivariable-adjusted HR, 0.97; 95% CI, 0.87-1.08; P = .59). TEER plus GDMT reduced the 30-day to 2-year rate of death or HFH compared with GDMT alone consistently in patients with increase LVEF and decrease LVEF (Pint = 0.75). Conclusions: Among patients with HF and severe SMR, early improvements in LVEF were more frequent with GDMT alone compared with TEER plus GDMT but were not associated with subsequent outcomes at 2 years. TEER reduced death or HFH during 2-year follow-up irrespective of early LVEF changes.

Contrast-induced encephalopathy (CIE) is an idiopathic reaction following iodine-contrast dye administration in patients undergoing angiographic procedures. While it has been well-documented following coronary and carotid interventions, literature on CIE following transcatheter aortic valve replacement is limited. We report the multidisciplinary management of 3 patients with CIE following transcatheter aortic valve replacement.

BACKGROUND: Clinical outcomes of patients presenting with STEMI are significantly improved by reducing time from vessel occlusion to coronary blood flow restoration. In an effort to improve outcomes, we developed a secure mobile application, STEMIcathAID, and designed a pilot project implementing the app into the workflow for STEMI patients transfer. The aim of the study is to assess the impact of the app on key metrics for STEMI transfer before (historic) and after app launch. METHODS: The pilot project included physicians, nurses and technicians from the Emergency Medicine and Nursing Departments at the referring center, the catheterization laboratory and transfer center. From July 2021 to February 2023, the referring center activated STEMIcathAID alarms in parallel with the previously established STEMI activation with traditional phone call to transfer center. RESULTS: One hundred eleven suspected STEMI calls were activated through the app with 66 accepted and 45 rejected cases; thirty-one STEMI cases with available device time were compared with 42 STEMIs activated through the traditional pathway before the app implementation. Median door-to-device time for STEMIcathAID-assisted transfer decreased from 106 to 86â¯min (pâ¯<â¯0.001). The significant improvement, 20â¯min (19%), of the key metric for interhospital transfer resulted in all STEMI cases meeting the AHA goal of door-to-device timeâ¯≤â¯120â¯min. In addition, median door-in-door-out time at the referral hospital decreased from 56 to 50â¯min (pâ¯=â¯0.01). CONCLUSIONS: Implementation of a mobile app into STEMI workflow of a large urban healthcare system significantly improved the quality of care for transfer of STEMI patients. TRIAL REGISTRATION: AHA Mission: Lifeline registry® is a national quality improvement program and is not subject to the institutional review board approval.

BACKGROUND: It remains unclear whether procedural myocardial infarction (pMI) and spontaneous myocardial infarction (spMI) have a similar impact on prognosis. OBJECTIVES: The aim of this study was to assess mortality after pMI and spMI. METHODS: Patients with chronic coronary syndrome (CCS) and baseline troponin ≤1× the upper reference level (URL) or with acute spMI who underwent percutaneous coronary intervention (PCI) were included. PMI was defined as post-PCI troponin increase >1× URL in patients with CCS. SpMI comprised any acute coronary syndrome with elevated troponin. The 1-year risk of all-cause death was assessed after pMI and spMI across 3 strata of troponin elevation (>1-5×, >5-35×, and >35× URL), with CCS patients having post-PCI troponin ≤1× URL as a reference group. Conventional troponin I was measured using the Architect methodology (Abbott). RESULTS: Among 10,707 patients undergoing PCI from 2012 to 2020, 8,515 patients presented with CCS and 2,192 with spMI. Among CCS patients, 913 (10.7%) had pMI. Troponin peaks >1-5×, >5-35×, and >35× URL were observed in 53%, 41%, and 6% of patients with pMI, and in 24%, 38%, and 37% of patients with spMI, respectively. Mortality at 1 year was higher after pMI (7.7%; adjusted HR: 4.40; 95% CI: 1.59-12.2), and spMI (8.5%; adjusted HR: 7.57; 95% CI: 5.44-10.5) with troponin peak >35× URL compared with no-MI (1.4%). Mortality was also increased after spMI with troponin peak >1-5× or >5-35× URL. CONCLUSIONS: Mortality at 1 year was significantly increased after pMI and spMI with troponin peak >35× URL, whereas for troponin levels ≤35× only spMI had a relevant impact on mortality.

A 93-year-old woman with symptomatic severe aortic stenosis and normal biventricular function was referred for transcatheter aortic valve replacement (TAVR) evaluation. Cardiac computed tomography revealed safe coronary heights and multiple large calcified mobile mass-like structures attached to the aortic valve (AV), confirmed also by transesophageal echocardiography, which were thought to be prominent Lambl's excrescences.

BACKGROUND: Patients may prefer percutaneous coronary intervention (PCI) over coronary artery bypass graft (CABG) surgery, despite heart team recommendations. The outcomes in such patients have not been examined. We sought to examine the results of PCI in patients who were recommended for but declined CABG. METHODS AND RESULTS: Consecutive patients with stable ischemic heart disease and unprotected left main or 3-vessel disease or Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score >22 who underwent PCI after heart team review between 2013 and 2020 were included. Patients were categorized into 3 groups according to heart team recommendations on the basis of appropriate use criteria: (1) PCI-recommended; (2) CABG-eligible but refused CABG (CABG-refusal); and (3) CABG-ineligible. The primary end point was the composite of death, myocardial infarction, or stroke at 1 year. The study included 3687 patients undergoing PCI (PCI-recommended, n=1718 [46.6%]), CABG-refusal (n=1595 [43.3%]), and CABG-ineligible (n=374 [10.1%]). Clinical and procedural risk increased across the 3 groups, with the highest comorbidity burden in CABG-ineligible patients. Composite events within 1 year after PCI occurred in 55 (4.1%), 91 (7.0%), and 41 (14.8%) of patients in the PCI-recommended, CABG-refusal, and CABG-ineligible groups, respectively. After multivariable adjustment, the risk of the primary composite outcome was significantly higher in the CABG-refusal (hazard ratio [HR], 1.67 [95% CI, 1.08-3.56]; P=0.02) and CABG-ineligible patients (HR, 3.26 [95% CI, 1.28-3.65]; P=0.004) groups compared with the reference PCI-recommended group, driven by increased death and stroke. CONCLUSIONS: Cardiovascular event rates after PCI were significantly higher in patients with multivessel disease who declined or were ineligible for CABG. Our findings provide real-world data to inform shared decision-making discussions.

BACKGROUND: Redo-transcatheter aortic valve replacement (TAVR) can pin the index transcatheter heart valve leaflets open leading to sinus sequestration and restricting coronary access. The impact of initial implant depth and commissural alignment on redo-TAVR feasibility is unclear. We sought to determine the feasibility of redo-TAVR and coronary access after SAPIEN 3 (S3) TAVR stratified by implant depth and commissural alignment. METHODS: Consecutive patients with native valve aortic stenosis were evaluated using multidetector computed tomography. S3 TAVR simulations were done at 3 implant depths, sizing per manufacturer recommendation and assuming nominal expansion in all cases. Redo-TAVR was deemed unfeasible based on valve-to-sinotubular junction distance and valve-to-sinus height <2 mm, while the neoskirt plane of the S3 transcatheter heart valve estimated coronary access feasibility. RESULTS: Overall, 1900 patients (mean age, 80.2±8 years; STS-PROM [Society of Thoracic Surgeons Predicted Risk of Operative Mortality], 3.4%) were included. Redo-TAVR feasibility reduced significantly at shallower initial S3 implant depths (2.3% at 80:20 versus 27.5% at 100:0, P<0.001). Larger S3 sizes reduced redo-TAVR feasibility, but only in patients with a 100:0 implant (P<0.001). Commissural alignment would render redo-TAVR feasible in all patients, assuming the utilization of leaflet modification techniques to reduce the neoskirt height. Coronary access following TAV-in-TAV was affected by both index S3 implant depth and size. CONCLUSIONS: This study highlights the critical impact of implant depth, commissural alignment, and transcatheter heart valve size in predicting redo-TAVR feasibility. These findings highlight the necessity for individualized preprocedural planning, considering both immediate results and long-term prospects for reintervention as TAVR is increasingly utilized in younger patients with aortic stenosis.

BACKGROUND: Coronary alignment is proposed as an alternative to commissural alignment for reducing coronary overlap during transcatheter aortic valve replacement (TAVR). However, largescale studies are lacking. OBJECTIVES: This study aimed to determine the incidence of coronary overlap with commissural vs coronary alignment using computed tomography (CT) simulation in patients undergoing TAVR evaluation. METHODS: In 1,851 CT scans of native aortic stenosis patients undergoing TAVR evaluation (April 2018 to December 2022),virtual valves simulating commissural and coronary alignment were superimposed on axial aortic root images. Coronary overlap was assessed based on the angular gap between coronary artery origin and the nearest transcatheter heart valve commissure, categorized as severe (≤15°), moderate (15°-30°), mild (30°-45°), and no-overlap (45°-60°). RESULTS: The overall incidence of moderate/severe and severe overlap with either coronary artery remained rare with either coronary or commissural alignment (coronary 0.52% left, 0.52% right; commissural 0.30% left, 3.27% right). Comparing techniques, coronary alignment reduced moderate/severe overlap only for the right coronary artery (0.38% vs 2.97%; P <0.0001). For the left coronary artery, both techniques showed similar moderate/severe overlap, but commissural alignment had significantly higher no-overlap rates (91.1% vs 84.9%; P < 0.0001). Fluoroscopic angle during valve deployment was strongly correlated between commissural and coronary alignment (r = 0.80; P < 0.001). CONCLUSIONS: Using CT simulation, the incidence of coronary overlap with transcatheter heart valve-commissure is rare with commissural alignment. Coronary alignment reduced right coronary overlap, whereas commissural alignment had higher rates of no left coronary overlap. Coronary alignment should be reserved only when commissural alignment results in severe coronary overlap.

BACKGROUND: Diabetes mellitus (DM) is associated with a high rate of major adverse cardiac events (MACE) after de novo coronary artery percutaneous coronary intervention (PCI). Whether patients with DM undergoing PCI for in-stent restenosis (ISR) experience a similar heightened risk of MACE is not known. Hence, we sought to compare the clinical outcomes of patients with and without DM undergoing PCI for ISR. METHODS: Patients undergoing first episode ISR PCI between January 2015 and December 2021 were included. The primary outcome of interest was MACE (all-cause death, myocardial infarction [MI], and target lesion revascularization [TVR]) at 1-year. RESULTS: A total of 3156 patients (56.7% with DM) underwent PCI for ISR during the study period. Patients with DM were younger, more likely to be female, and had a higher prevalence of comorbidities. At 1-year follow-up, DM was associated with a higher rate of MACE (22.4% vs. 18.7%, unadjusted HR 2.03, 95%CI(1.27-3.25), p = 0.003). All-cause mortality and MI were significantly more frequent among people with DM at 1-year follow-up. The rate of TVR was similar in both groups (17.9% vs. 16.0%, unadjusted HR 1.14, 95%CI (0.94-1.37), p = 0.180). On adjusted analysis, there was no significant difference in the rate of MACE (AHR 1.07, 95%CI(0.90 - -1.29), p = 0.444), all-cause death (AHR 1.54, 95%CI(0.93-2.54), p = 0.095) or MI (AHR 1.10, 95%CI(0.74-1.63), p = 0.652). CONCLUSION: ISR PCI in patients with DM was associated with a higher rate of MACE at 1-year follow-up. However, this increased risk was no longer significant after adjusting for baseline characteristics.

BACKGROUND: Markers of systemic inflammation, such as high-sensitivity C-reactive protein (hsCRP), have been associated with the occurrence of major adverse cardiovascular and cerebrovascular events (MACCE) in patients undergoing percutaneous coronary intervention (PCI). Whether this risk varies according to the presence of high bleeding risk (HBR) conditions is unclear. OBJECTIVES: The aim of this study was to evaluate the impact of systemic inflammation, as measured by hsCRP levels and cardiovascular outcomes in patients stratified by HBR status following PCI. METHODS: Consecutive patients undergoing PCI between 2012 and 2019 with baseline hsCRP levels were included. High hsCRP was defined as >3 mg/L, and HBR was defined per the Academic Research Consortium HBR criteria. The primary outcome was MACCE, including all-cause death, myocardial infarction, or stroke at 1 year. All bleeding was assessed as a secondary outcome. RESULTS: A total of 15,150 patients were included, and 40.4% (n = 6,125) qualified as HBR. The adjusted risk for MACCE was consistently higher in patients with high hsCRP in both HBR (adjusted HR [aHR]: 1.49; 95% CI: 1.18-1.87) and non-HBR (aHR: 1.87; 95% CI: 1.31-2.66) subgroups, with no interaction between HBR status and hsCRP level (Pinteraction = 0.26). Conversely, although bleeding risk was higher in the HBR cohort, hsCRP did not predict the occurrence of bleeding in either the HBR (aHR: 1.04; 95% CI: 0.82-1.31) or the non-HBR (aHR: 0.99; 95% CI: 0.71-1.39) subgroup (Pinteraction = 0.539). CONCLUSIONS: Elevated hsCRP at the time of PCI is associated with a higher risk for ischemic but not bleeding events, irrespective of HBR status.

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.

Rotational atherectomy (RA) is widely used in the percutaneous treatment of heavily calcified coronary artery lesions in patients with chronic coronary syndromes (CCS). However, the safety and efficacy of RA in acute coronary syndrome (ACS) is not well established and is considered a relative contraindication. Therefore, we sought to evaluate the efficacy and safety of RA in patients presenting with non-ST-elevation myocardial infarction (NSTEMI), unstable angina (UA), and CCS. Consecutive patients who underwent percutaneous coronary intervention with RA between 2012 and 2019 at a tertiary single center were included. Patients presenting with ST-elevation myocardial infarction (MI) were excluded. The primary end points of interest were procedural success and procedural complications. The secondary end point was the risk of death or MI at 1 year. A total of 2,122 patients who underwent RA were included, of whom 1,271 presented with a CCS (59.9%), 632 presented with UA (29.8%), and 219 presented with NSTEMI (10.3%). Although an increased rate of slow-flow/no-reflow was noted in the UA population (p = 0.03), no significant difference in procedural success or procedural complications, including coronary dissection, perforation, or side-branch closure, was noted (p = NS). At 1 year, there were no significant differences in death or MI between CCS and non-ST-elevation ACS (NSTE-ACS: UA + NSTEMI; adjusted hazard ratio 1.39, 95% confidence interval 0.91 to 2.12); however, patients who presented with NSTEMI had a higher risk of death or MI than CCS (adjusted hazard ratio 1.79, 95% confidence interval 1.01 to 3.17). Use of RA in NSTE-ACS was associated with similar procedural success without an increased risk of procedural complications compared with patients with CCS. Although patients presenting with NSTEMI remained at higher risk of long-term adverse events, RA appears to be safe and feasible in patients with heavily calcified coronary lesions presenting with NSTE-ACS.
