Publication number: 20220079550Abstract: The invention provides a method for calculating an end-diastolic pressure-volume relationship. The method includes obtaining a cardiac input representing a region of interest, wherein the region of interest comprises a left ventricle and a left atrium of a subject. An end of diastasis volume of the left ventricle is then determined based on the cardiac input, wherein diastasis is a stage of diastole during a heart cycle before atrial contraction. Further, an end of diastasis pressure in the left atrium is determined based on the cardiac input and a linearized ventricular pressure-volume relationship is generated based on the end of diastasis volume of the left ventricle and the end of diastasis pressure in the left atrium. An end-diastolic pressure-volume relationship is then determined based on an end-diastolic volume of the left ventricle and the linearized ventricular pressure-volume relationship.Type: ApplicationFiled: December 19, 2019Publication date: March 17, 2022Inventors: Kevin Daniel Seng Hung LAU, Marco BARAGONA, Ralph Theodorus Hubertus MAESSEN, David PRATER
