We aimed to identify optimal timing of PVR and couple CMR-based metrics with contemporaneous echocardiographic metrics. From June 2002 to January 2019, 174 patients with severe pulmonary regurgitation and peak RV outflow tract gradient <30 mm Hg underwent PVR at Cleveland Clinic. Mean age was 35 ± 16 years and 60 (34%) had concomitant tricuspid valve surgery. RV end diastolic area index (RVEDAi) and function metrics were measured by offline image review on preoperative and 794 postoperative echocardiograms. Contemporaneous RV end diastolic volume index (RVEDVi) was assessed on CMR and correlated to RVEDAi. Multiphase nonlinear mixed-effects models were used to analyze the longitudinal change in RV size and function after PVR. RVEDAi was correlated with RVEDVi (P < 0.0001, r = 0.59). RVEDAi decreased slowly over 10 years following PVR. An inflection point at 24 cm2/m2 was noted at 1 year post-PVR and was associated with failure of RV reverse remodeling and RVEDVi ≥150 mL/m2. Compared to patients with preoperative RVEDVi ≥150 mL/m2, patients with RVEDVi <150 mL/m2 had accelerated recovery of longitudinal trajectories of RV size and function metrics on echocardiograms. Reverse remodeling of RV following PVR is an ongoing process. Current accepted threshold values for PVR are associated with greatest RV recovery, suggesting that earlier PVR is warranted. Echocardiography can potentially be utilized in lieu of CMR for surveillance and interventional triage.</div>","PeriodicalId":48592,"journal":{"name":"Seminars in Thoracic and Cardiovascular Surgery","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9231945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From January 2017 to July 2021, 301 consecutive type A repairs were evaluated at our institution. Starting in 2019, all type A aortic dissections were performed in a fixed-fluoroscopy, hybrid operating room. Propensity score matching was used to control baseline patient characteristics between traditional and hybrid operating room approaches. There were 144 patients in the traditional group and 157 in the hybrid group. In the hybrid group, 41% (64/157) underwent intraoperative angiograms, and of those, 58% (37/64) received at least 1 endovascular intervention.

We investigated the effect of intraoperative support strategies on endothelial injury biomarkers and short-term posttransplant outcomes. Adults undergoing bilateral lung transplantation with No-Support, venoarterial (V-A) ECMO, or CPB were included. Plasma samples pre- and post-transplant were collected for Luminex assay to measure endothelial injury biomarkers including syndecan-1 (SYN-1), intercellular adhesion molecule-1 (ICAM-1), and matrix metalloprotease-9. Fifty five patients were included for analysis. The plasma level of SYN-1 at arrival in the intensive care unit was significantly higher with CPB compared to V-A ECMO and No-Support (P < 0.01). The rate of primary graft dysfunction grade 3 (PGD3) at 72 hours was 60.0% in CPB, 40.1% in V-A ECMO, and 15% in No-Support (P = 0.01). Postoperative plasma levels of SYN-1 and ICAM-1 were significantly higher in recipients who developed PGD3 at 72 hours. SYN-1 levels were also significantly higher in patients who developed acute kidney injury and hepatic dysfunction after transplant. Postoperative, SYN-1 upon intensive care arrival was found to be a significant predictive biomarker of PGD3, acute kidney injury, and hepatic dysfunction following lung transplantation. CPB is associated with higher plasma concentrations of SYN-1, a marker of endothelial glycocalyx degradation, upon arrival to the intensive care unit. Higher levels of SYN-1 are predictive of end-organ dysfunction following lung transplantation. Our data suggests that intraoperative strategies aimed at modulating endothelial injury will help improve lung transplantation outcomes.</div>","PeriodicalId":48592,"journal":{"name":"Seminars in Thoracic and Cardiovascular Surgery","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10822410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
