Abstract Objective: The correlation between intraoperative blood pressure thresholds and outcomes in elderly patients undergoing noncardiac surgery remains inadequately characterized. This study aims to assess the association between intraoperative hypotension (IOH) parameters—specifically blood pressure thresholds and duration—and severe adverse outcomes in elderly patients with or without structural or congenital heart disease. Methods: A retrospective evaluation was performed on 846 elderly patients who underwent non-cardiac surgical procedures at Shanghai Songjiang District Hospital in China, from 01 January 2020, to 31 December 2021. Forty-one patients meeting specific exclusion criteria were excluded from the analysis, yielding a final sample size of… More >

Abstract Background: Cardiac magnetic resonance (CMR) imaging following transcatheter pulmonary valve replacement (TPVR) allows for the assessment of right ventricular (RV) volume. This study aimed to evaluate early- to mid-term findings after the procedure. Methods: A total of 21 patients with repaired tetralogy of Fallot who underwent TPVR were enrolled in the study. CMR data before and after the procedure were compared. The median interval between the procedure and the post-TPVR CMR was 9 months (range: 6–18 months). Results: RV volumes and RV end-diastolic volume indices were significantly lower after TPVR compared to before the procedure. RV volume… More >

Abstract Background: Congenital heart disease (CHD) is characterized by a high incidence and low detection rate. The shortage of pediatric echocardiologists limits the routine ultrasound screening for CHD in many institutions. Deep learning has emerged as a promising tool to enhance the CHD diagnosis. This study aims to develop and evaluate a two-branch, two-stage intelligent algorithm (OBICnet) based on echocardiographic images to predict and classify common CHD in pediatric patients. Methods: A total of 8543 static color Doppler images from 3134 children were analyzed, with each child contributing 1 to 7 standard sectional views. The dataset was… More >

Abstract Background: Hypoattenuating leaflet thickening (HALT) is a reported complication following percutaneous pulmonary valve implantation (PPVI) Case description: A 32-year-old man with a history of repaired Tetralogy of Fallot (TOF) underwent PPVI for symptomatic severe pulmonary regurgitation (PR). The postoperative course was complicated by HALT diagnosed by computed tomography (CT) within 24 h of the procedure. Anticoagulation therapy was administered, and reassessment CT at 4 months showed resolution of HALT. Conclusion: HALT following PPVI is managed with anticoagulation yet consensus for optimal management strategy is lacking. More >
