A Multicenter Study on the Normal Reference Range and Clinical Significance of the Right Atrioventricular Coupling Index Assessed by Artificial Intelligence-Based Three-Dimensional Echocardiography

This multicenter study aims to establish the normal reference range of the Right Atrioventricular Coupling Index (RACI) in healthy Chinese adults using AI-based 3DE technology. It will also analyze the correlation between RACI and physiological parameters such as age, gender, and body surface area. Additionally, the study will explore the variation characteristics of RACI in patients with pulmonary hypertension, heart failure, tricuspid regurgitation, and atrial septal defect, and evaluate the clinical value of RACI in disease diagnosis, differential diagnosis, and risk stratification.

Cerebral Microembolization Associated With PFO Closure

This study aims to investigate (1) the de novo cerebral microembolization in patients who undergo transcatheter closure of PFO or ASD, and (2) evaluate the relationship between de novo cerebral microembolization and in situ thrombus within PFO.

Cera™ ASD Occluder Post-Market Clinical Follow-Up Study

The objective of this post-market study is to: * collect real-word clinical data and confirm the long-time safety and performance of the Lifetech Cera™ ASD Occluder * identify previously unknown side-effects

Improving Care for Children With Congenital Heart Disease.

Establish a cardiovascular biomarker profile to help screening for congenital heart disease in infants and children as well as use non-invasive cardiac imaging in combination with such profiling to better predict the need for future cardiac interventions such as open heart surgery or cardiac catheter intervention in selected types of with congenital heart disease.

Efficacy of Three Dimensional Transesophageal Echocardiography for Percutaneous Device Closure in Atrial Septal Defect

Background: Three-dimensional echocardiographic image for atrial septal defect (ASD) is useful for evaluation of defect size and shape. The investigators suggested optimal device size using three-dimensional transesophageal echocardiographic image and our formula in previous study. Purpose: In this study, the investigators seek to predict the correct device size and confirm the accuracy of the formula that we made before device closure in ASD patients.

Lifetech CeraFlex™ ASD Closure System Post-Market Clinical Follow-Up

The objective of this post-market registry is to assess the clinical use of the Lifetech CeraFlex™ Closure System in a real-world and on-label fashion.

Cardiac Interventional ICE Imaging Trial

The INTELICE trial is a prospective, multicenter, 1:1 randomized controlled non-inferiority study. It aims to compare a novel intracardiac echography (ICE) catheter and combined ultrasound system with existing commercial ones. The evaluation will be conducted on patients undergoing planned intracardiac interventional process.

AWARE Registry: Wearable ECG in Structural Heart Interventions

This study is a multi-center (Sinchon Severance hospital / Gangnam Severance hospital), prospective cohort observational study to patients who had undergone structural heart intervention including device closure for secundum type atrial septal defect or Patent foramen ovale. Transthoracic echocardiography will be performed before the procedure, immediately after, and at 6, 18, 30 months after the procedure. Wearable ECG monitoring (\> 3 days) will be performed before the procedure or immediately after procedure. Demographic, laboratory, hemodynamic data during procedure, and non-invasive imaging dat are obtained.

Canadian Adult Congenital Heart Disease Intervention Registry

The ACHDi Registry study will create a foundational database for adult congenital heart disease interventions. This Pan-Canadian Registry will collect clinical and patient-reported information that will enable the evaluation of care processes and outcomes in five most common ACHDi interventions by enabling prospective and retrospective registry-based studies to answer important clinical practice and policy-relevant questions.
