Morphological Parameters of In-stent RESTenosis Assessed and Identified by OCT
OCT during angiography provides a detailed analysis of the stents and potential complications: the presence of neoatherosclerosis with or without plaque rupture, intimal hyperplasia, stent under-deployment, stent fracture and distal or proximal progression of the atherosclerosis.

Assessment of Paravalvular Leak After TAVI by Hemodynamic Measurements and Cardiac MRI
Grading paravalvular leakage after TAVI is difficult. Echocardiography and angiography systematically underestimate paravalvular leakage (PVL) as compared to cardiac MRI. Hemodynamic measurements are used to aid decision making directly after TAVI implantation.

Impact of Mitral Regurgitation on Coronary Haemodynamics and Instantaneous Effect of Transcatheter Mitral Valve Repair
In the present study, the investigators aim to use the in-vivo Transcatheter Mitral Valve Repair (TMVR) model to determine how Mitral Regurgitation (MR) affects coronary hemodynamics in patients affected with severe MR and concomittant angiographically-documented coronary artery disease. The investigators will also provide unique physiologic data on the acute effect …

A Blind Self Controlled Multicenter Clinical Trial on the Effectiveness and Safety of Noninvasive Flow Reserve Score Analysis Software for Coronary Angiography
The data of the experimental group was defined as: FFR value at the distal end of stenosis was obtained by calculating the original DICOM data of coronary CT angiography (CCTA) before operation with the non-invasive blood flow reserve analysis software of Hangzhou ArteryFlow Technology Co., Ltd.
