In this study, we show the use of three-dimensional printing models for preoperative planning of transcatheter valve replacement in a patient with an extreme porcelain aorta. A 70-year-old man with severe aortic stenosis and a porcelain aorta was referred to our center for transcatheter aortic valve replacement. Unfortunately, the patient died after the procedure because of a potential ischemic event. Therefore, we decided to fabricate three-dimensional models to evaluate the potential effects of these constructs for previous surgical planning and simulation of the transcatheter valve replacement.

Severe tricuspid regurgitation (TR) can lead to significant enlargement of the right atrium (RA) and poses unique clinical challenges. We report this case of a 17-year-old boy previously misdiagnosed with Ebstein anomaly who presented with dyspnea and palpitations. Initial examination revealed irregular heart rhythm, distended neck veins, and a significant murmur.

Introduction: Whilst aortic stenosis remains the most prevalent valvular abnormality, the management of asymptomatic severe aortic stenosis remains a clinical challenge. Recently, two randomised-controlled trials (RCTs) - EVOLVED (Early Intervention in Patients With Asymptomatic Severe Aortic Stenosis and Myocardial Fibrosis) and Early TAVR (Transcatheter Aortic-Valve Replacement for Asymptomatic Severe Aortic Stenosis) - have been published, alongside an extended follow-up from the AVATAR (Aortic Valve Replacement Versus Conservative Treatment in Asymptomatic Severe Aortic Stenosis) study.
Evidence Acquisition: In response, we conducted a systematic review of PubMed, Ovid, and Cochrane databases, identifying RCTs up to October 29, 2024, that compared early intervention with conventional management.

Objective: Valve selection in acute type A aortic dissection (ATAAD) requiring aortic root replacement is challenging given the clinical acuity, unknown patient preferences, risk of surgical bleeding, and limited life expectancy. We sought to identify long-term outcomes of mechanical versus bioprosthetic aortic root replacement in young patients with ATAAD.
Methods: Retrospective review of our institution's database of ATAAD was conducted to identify patients aged 65 years and younger who underwent mechanical Bentall (mech-Bentall) or bioprosthetic Bentall (bio-Bentall) for ATAAD from 2002 to 2022.

Objective: To compare the clinical outcomes of double-valve replacement (DVR) using bovine pericardial and porcine bioprostheses, using a nationwide administrative claims database.
Methods: Adult patients (age ≥40 years) who underwent bioprosthetic DVR between 2003 and 2018 were identified from the Korean National Health Insurance Service database. The outcomes of interest were all-cause mortality, cardiac mortality, and valve-related events, including the incidences of reoperation, endocarditis, systemic thromboembolism, and major bleeding.

Objectives: Left ventricular vortex dynamics play a crucial role in cardiac function but are significantly altered by mitral valve diseases or surgical interventions. Such hemodynamic changes may lead to maladaptive intracardiac vortices, potentially triggering pathways associated with progressive left ventricular remodeling and thrombosis. This study assessed left ventricular hemodynamics under both physiological and pathological conditions using a biohybrid in vitro platform, aiming to analyze the impact of these conditions on cardiac function.
