“…[5] has proposed a set of measurements: max (RVOT) diameter, min diameter and diameter at the main bifurcation region from which the exact location for anchoring the valve stent is defined [6]. PPVI intervention is avoided by patients with RVOT diameter > 22mm due to device limitation [1,4,5].…”

“…Percutaneous pulmonary valve implantation (PPVI) [4] is a new developed technique for transcatheter placement of a valve stent. The main difficulties of PPVI are: the assessment of the pulmonary trunk and the right ventricle outflow track (RVOT < 22mm) before treatment [4], the classification of patients suitable for the procedure [5] and identification of the exact location for anchoring the stent [6]. Hence, precise assessment of the morphology and dynamics is crucial for the pre-procedural planning and successful intervention of PPVI.…”

Abstract. Pulmonary valve disease affects a significant portion of the global population and often occurs in conjunction with other heart dysfunctions. Emerging interventional methods enable percutaneous pulmonary valve implantation, which constitute an alternative to open heart surgery. As minimal invasive procedures become common practice, imaging and non-invasive assessment techniques turn into key clinical tools. In this paper, we propose a novel approach for intervention planning as well as morphological and functional quantification of the pulmonary trunk and valve. An abstraction of the anatomic structures is represented through a four-dimensional, physiological model able to capture large pathological variation. A hierarchical estimation, based on robust learning methods, is applied to identify the patient-specific model parameters from volumetric CT scans. The algorithm involves detection of piecewise affine parameters, fast centre-line computation and local surface delineation. The estimated personalized model enables for efficient and precise quantification of function and morphology. This ability may have impact on the assessment and surgical interventions of the pulmonary valve and trunk. Experiments performed on 50 cardiac computer tomography sequences demonstrated the average speed of 202 seconds and accuracy of 2.2mm for the proposed approach. An initial clinical validation yielded a significant correlation between model-based and expert measurements. To the best of our knowledge this is the first dynamic model of the pulmonary trunk and right ventricle outflow track estimated from CT data.

“…For nearly four decades open prosthetic valve replacement has been the only option for most of these patients, but in 2000 Phillip Bonhoeffer replaced the fi rst heart valve (a pulmonary valve) percutaneously (3) and in 2002, Cribier performed the fi rst percutaneous replacement of an aortic valve. (4) Percutaneous heart valve replacement has enjoyed a lot of interest with numerous new developments since then.…”

“…This technique was later successfully applied in failing patients to the incompetent conduits originally placed for the treatment of congenital pulmonary atresia. 8,9 Finally, came the signal report by Cribier et al 10 of the implantation of a stent-mounted biological membrane valve in a patient with inoperable critical aortic stenosis in April of 2002.…”
