Development of an Algorithm to Differentiate Heart Murmurs Using Electronic Stethoscopes
The Eko CORE and DUO stethoscopes are FDA-approved electronic devices that have the capacity to record heart sounds. The study seeks to expand murmur detection to include VHD classification through the development of novel ML algorithms that are able to distinguish between systolic vs. diastolic vs. continuous murmurs, as well …

Registry for Invasive and Non-invasive Anatomical Assessment and Outcome of Coronary Artery Anomalies
The possible presence of an interarterial/intramural course is the primary cause for an oval proximal vessel shape and/or proximal vessel narrowing, which may lead under stress conditions to a "dynamic compression" of the vessel (compared to "fixed" stenosis in coronary artery disease). To mimic these conditions, dobutamine and volume challenge …

Effect of FFRCT-angio in Functional Diagnosis of Coronary Artery Stenosis
Coronary CT angiography (CTA) or invasive coronary angiography (CAG) is usually performed to evaluate the severity of coronary stenosis depending on the probability of CAD. However, the stenosis severity is not closely corresponding with the hemodynamic significance in coronary arteries.

Post-Marketing Follow-Up of Long-term Type Ureteral Stent Set
Although there are several reports regarding the effectiveness of long-term ureteral stents for malignancy ureteral obstruction, ureteral stricture and urolithiasis, the experience is limited about the long-term ureteral stents made by Taiwan. The investigators have to propose the 5-year post-market survey report.

Effect of Pre-existing Adjacent Segment Degeneration on Long-term Effectiveness After Lumbar Fusion Surgery
Important adjacent pre-existing degeneration factors include discs degenerated, facets and ligamentum flavum tropism which could lead to spinal canal stenosis (SCS). This study will focus on the effects of pre- existing adjacent degeneration (disc factors and spinal canal stenosis factors) on long-term postoperative outcomes.
