	title = {A fast virtual surgery platform for many scenarios haemodynamics of patient-specific coronary artery bypass grafts},
	year = {2016},
	institution = {Submitted},
	abstract = {A fast computational framework is devised to the study of
several configurations of patient-specific coronary artery bypass
grafts. This is especially useful to perform a sensitivity
analysis of the haemodynamics for different flow conditions
occurring in native coronary arteries and bypass grafts, the
investigation of the progression of the coronary artery disease and the choice of the most appropriate surgical procedure.
A complete pipeline, from the acquisition of patientspecific
medical images to fast parametrized computational
simulations, is proposed. Complex surgical configurations
employed in the clinical practice, such as Y-grafts and sequential
grafts, are studied. A virtual surgery platform based
on model reduction of unsteady Navier Stokes equations for
blood dynamics is proposed to carry out sensitivity analyses
in a very rapid and reliable way. A specialized geometrical
parametrization is employed to compare the effect of stenosis
and anastomosis variation on the outcome of the surgery
in several relevant cases.},

	year = {2015},
	abstract = {In this work a reduced-order computational framework for the study of haemodynamics
in three-dimensional patient-specific configurations of coronary artery bypass grafts
dealing with a wide range of scenarios is proposed. We combine several efficient algorithms to face at the same time both the geometrical complexity involved in the description of the vascular network and the huge computational cost entailed by time dependent patient-specific flow simulations. Medical imaging procedures allow to reconstruct patient-specific configurations from clinical data. A centerlines-based parametrization is proposed to efficiently handle geometrical variations. POD{\textendash}Galerkin reduced-order models are employed to cut down large computational costs. This computational framework allows to characterize blood flows for different physical and geometrical variations relevant in the clinical practice, such as stenosis factors and anastomosis variations, in a rapid and reliable way. Several numerical results are
discussed, highlighting the computational performance of the proposed framework, as well as its capability to perform sensitivity analysis studies, so far out of reach.},
