Isolated direct metastasis of uterine cervical carcinoma to the right ventricular endocardium is very rare. A 68-year-old woman was initially diagnosed as having stage IIIb squamous cell carcinoma of the uterine cervix, and was treated with radiation therapy. After 2 years, she developed heart failure and presented with a mass in the right ventricle. The(More)
Human induced pluripotent stem cells (hiPSCs) are a robust source for cardiac regenerative therapy due to their potential to support autologous and allogeneic transplant paradigms. The in vitro generation of three-dimensional myocardial tissue constructs using biomaterials as an implantable hiPSC-derived myocardium provides a path to realize sustainable(More)
Biological tissues have complex, three-dimensional (3D) organizations of cells and matrix factors that provide the architecture necessary to meet morphogenic and functional demands. Disordered cell alignment is associated with congenital heart disease, cardiomyopathy, and neurodegenerative diseases and repairing or replacing these tissues using engineered(More)
The current study describes a scalable, porous large-format engineered cardiac tissue (LF-ECT) composed of human induced pluripotent stem cells (hiPSCs) derived multiple lineage cardiac cells with varied 3D geometries and cell densities developed towards the goal of scale-up for large animal pre-clinical studies. We explored multiple 15 × 15 mm ECT(More)
We reviewed our cut and sew pulmonary vein isolation (PVI) series for chronic or paroxysmal atrial fibrillation (Af). Intraoperative evaluation of sinus nodal function with electrical defibrillation and atrial pacing and the incision to mitral annulus adding to PVI were important factors to restore sinus rhythm. Ninety-two percent of the patients with the(More)
