Purpose
The FUPEC (Follow-Up Pre-EClampsia) study aims to investigate the presence and development of cardiovascular risk factors, cardiovascular disease, as well as cardiovascular health following a pregnancy complicated by severe pre-eclampsia.

Participants
The FUPEC study is an open-cohort study conducted within routine care at the FUPEC clinic at Erasmus Medical Center in the Netherlands. This clinic is specifically designed for the cardiovascular follow-up of patients who have experienced severe pre-eclampsia. Women with a history of severe pre-eclampsia are invited to the FUPEC clinic at 6 weeks, 3 months, 1 year and every 2 years thereafter postpartum until they are 50 years of age. Clinical and biochemical data are routinely collected, encompassing pregnancy characteristics and outcomes, anthropometric measurements, cardiovascular risk factors, cardiovascular health scores, carotid intima-media thickness—including vascular age and ambulatory blood pressure measurements. Additionally, blood and urine samples are collected and stored in a biobank.

Findings to date
The first patient was enrolled in April 2011. As of March 2024, a total number of 1268 women have been enrolled in the FUPEC study, with an annual enrolment rate of 100–150 new patients. At inclusion, women had a median age of 33.5 years (IQR 30.1–37.9). At their first FUPEC visit, women were a median of 4.9 months (1.9–29.4) after delivery. At the first visit, the median body mass index was 25.7 (IQR 23.0–29.9) kg/m2, 23.4% of participants were using antihypertensive medication and 6.4% were smoking. Preliminary analyses of 24-hour blood pressure patterns and carotid intima-media thickness have previously been conducted on a subset of the cohort, with details provided in the ‘Findings to Date’ section.

Future plans
The FUPEC cohort serves as a robust clinical data source and biobank that can be used for future studies and collaborative research answering, for example, questions on the aetiology, risk factors and short-term and long-term complications of pregnancies complicated by severe pre-eclampsia. Since the FUPEC cohort is integrated with routine care, there is no strict completion of data collection, allowing for flexible data acquisition.

Introduction/Research Question:Allosensitization, the presence of circulating anti-HLA antibodies, is a barrier in heart transplantation (HT), restricting the donor pool size, and leading to increased waitlist mortality and rejection risk post-HT. Desensitization therapies can be used to broaden the donor pool in highly sensitized patients, defined as pre-HT calculated panel reactive antibodies (cPRA)≥50%, for antibodies with mean fluorescence intensity (MFI) >10,000. There is paucity of data on longer-term outcomes in such high-immunological risk patients.Methods:Sensitized patients with pre-HT cPRA >50%, who were treated with desensitization and then received HT between 2011-2022 at Cedars-Sinai Medical Center were included. Desensitization therapies included bortezomib, rituximab, tocilizumab, obinutuzumab, intravenous immunoglobulin (IVIG), and plasmapheresis. cPRA, donor-specific antibody (DSA) levels, and post-HT clinical outcomes were assessed up to 5-year follow-up, loss to follow-up, or death.Results:40 patients were analyzed. 77.5% of patients were female, and all had at least 1 risk factor for sensitization. cPRA decreased from 84.5±13.5% at baseline to 74.1±22.4% after completion of desensitization therapy, prior to transplant (p=0.005). Mean follow-up time post-HT was 4.3±2.9 years. 45.0% of patients had antibody-mediated rejection (AMR), 12.5% had CAV. Overall survival was 94.9%, 92.1%, and 87.5% at 1, 3, and 5 years respectively. All patients except 1 had normal left ventricular function at last follow-up. 72.5% of patients were transplanted in the presence of DSA, and 60.0% underwent post-HT induction with eculizumab in addition to antithymocyte globulin (ATG)/IVIG, while the remaining received ATG/IVIG alone. Among HT recipients with pre-formed DSA, 41.4% had high-level DSA (MFI > 10,000) at time of HT. At 6-12 months post-HT, only 17.2% had high-level DSA, and 41.4% had resolution of DSA.Conclusion:Highly sensitized HT candidates who underwent pre-HT desensitization had comparable survival and CAV rates as compared to the general HT population reported in the literature. However, sensitized patients experienced higher rates of AMR which were not associated with graft dysfunction or mortality.

Circulation, Volume 150, Issue Suppl_1, Page A4143224-A4143224, November 12, 2024. Background:Left Atrial Appendage (LAA) Occlusion with Amulet has shown promising results in achieving complete closure with minimal periprocedural leak. Amulet’s dual-sealed technology and numerous sizing options provide versatility for different LAA morphologies. Pre-procedural CT is routinely recommended for pre-procedural planning. However, this brings risks including use of contrast, risk of renal failure, radiation exposure, and patient inconvenience. Here, we share initial results of our Amulet implantation protocol without pre-procedural CT: 83 cases were reviewed; number of devices used, procedural time, periprocedural bleeding complications, success in coming off oral anticoagulation, and incidences of stroke and embolism were followed.Methods:We followed 83 AF patients who underwent LAA closure with Amulet, implanted with intraprocedural TEE, intracardiac left atrial echocardiography, and intraprocedural angiography. Pre-procedural CT was not used. Patients were followed to assess safety and efficacy of this protocol. Safety endpoints included rates of procedural and bleeding complications. Efficacy endpoints included rates of stroke and embolism, and number of devices used.Results:All 83 procedures were successfully completed with no perioperative procedural complications and no documented leaks on follow-up TEE. Patients had early ambulation with closure. On average, 1.14 devices were used per case: 88% of cases required 1 device, and nine cases required 2 devices; one case required 4 devices to fit as patient was noted to have an interrupted IVC, requiring implantation via right IJV. There were no cases of stroke or embolism following implantation, and all patients were safely able to come off oral anticoagulation.Conclusions:Results demonstrate that Amulet with its dual-sealed technology can be effectively and safely implanted without pre-procedural CT. No perioperative complications were observed. 88% of cases closed with single device usage. No post-procedure leaks were noted on follow-up TEE. Safety endpoints revealed minimal adverse events, with 2 cases of late pericardial effusion managed without long-term consequences. This protocol demonstrated high efficacy, as all patients were successfully able to come off oral anticoagulation with no reported strokes or embolic events. Intraprocedural TEE, intracardiac left atrial echocardiography, and intraprocedural angiography are typically appropriate for periprocedural sizing of the device.

Circulation, Volume 150, Issue Suppl_1, Page A4144651-A4144651, November 12, 2024. Introduction:Post-transcatheter aortic valve replacement (TAVR) pacemaker (PPM) implantation is a known complication. Chronic total occlusion (CTO) of coronary arteries is common in TAVR patients and is a marker of advanced coronary calcification. Its influence on the requirement for PPM post-TAVR remains unclear. We investigated the association between pre-existing CTO and the incidence of PPM post-TAVR.Methods:A retrospective cohort study was conducted using the National Inpatient Sample database from 2018-2020 with 205,565 patients who underwent TAVR. Propensity score matching was utilized to create a matched cohort of patients with and without CTO, balancing key variables such as age, sex, elective procedure status, and comorbid conditions (heart failure, arrhythmias, pulmonary circulation disorders, peripheral vascular disorders, and complicated diabetes). Outcomes measured included the requirement for PPM implantation post-TAVR, in-hospital mortality, and major adverse cardiac events (MACE). Weighted samples were utilized and p-value
