Predicted Coronary Occlusion and Impella Salvage During Valve-in-Valve Transcatheter Aortic Valve Replacement.

We describe an interesting case of a 71 years old fragile female, with progressive shortness of breath on exertion and ankle swelling, cardiac failure NYHA class III. She also had chest irradiation due to Hodgkin's disease many years before, previous surgical aortic valve replacement using bioprosthetic stent-less Freestyle #25 mm valve (Medtronic, Inc) in 2000 for severe aortic stenosis, history of cardiac arrest in 2012 and angioplasty to ostial RCA, PCI to ostial RCA in 2014, CABG (RA graft to RCA) in 2014 (RCA intra-stent restenosis with refractory ischemia), anemia requiring regular transfusions, bronchiectasis and chronic kidney disease. Because of the great comorbidities, STS 4.

Deep learning segmentation of coronary calcified plaque from intravascular optical coherence tomography (IVOCT) images with application to finite element modeling of stent deployment.

Because coronary artery calcified plaques can hinder or eliminate stent deployment, interventional cardiologists need a better way to plan interventions, which might include one of the many methods for calcification modification (e.g., atherectomy).
