SynSeq: End-to-End SYNTAX Score Prediction from Coronary Angiography Videos

SynSeq is a video‑based method that directly predicts the SYNTAX score from coronary angiography videos, using targeted preprocessing and a zero‑inflation‑aware loss with linear target scaling. On the CardioSyntax dataset it outperforms prior state‑of‑the‑art approaches, improving $R^2$ by 0.55, reducing prediction bias by 93.1%, and delivering consistent performance across three expert graders. The model also achieves a weighted $F_1$‑score of 0.80 for revascularization treatment recommendations, approaching inter‑expert agreement.

MAC-XA: Multi-view Anatomy-Correspondence Fusion for Coronary Stenosis Reporting from X-ray Angiography

Multi-view reasoning in coronary X-ray angiography is inherently a cross-projection geometric problem, yet automated report generation in this setting remains largely unexplored. The 3D vascular topology leads to projection-dependent branch overlap and foreshortening, rendering single-view modeling fundamentally incomplete and unstable for lesion localization and stenosis grading.

ReG-SAM: Reference Graph-Driven SAM for 2D Foundational Vessel Segmentation

ReG-SAM is a SAM-based framework designed for 2D vessel segmentation in medical images. It introduces reference graph prompt embeddings (GPEs) and vascular prototype embeddings (VPEs) to capture global spatial and fine-grained modality-specific vessel features, respectively. By building a modality-wise vascular database and learning these embeddings from reference masks, ReG-SAM consistently outperforms existing baselines across 19 datasets, especially on thin vessels.
