Clinical anatomy of the spatial structure of the right ventricular outflow tract.

Background: The right ventricular outflow tract (RVOT) is located above the supraventricular crest and reaches the level of the pulmonary valve. Detailed knowledge of the RVOT spatial structure and its morphology is extremely important for cardiac invasive therapeutic procedures.

Objectives: To examine the spatial structure of the RVOT using virtual models of the right ventricle (RV) interior obtained post mortem.

Individual variability of vascularization of the anterior papillary muscle within the right ventricle of human heart.

Background: To date there is scarce published evidence reporting the dual blood supply reaching anterior papillary muscle (APM), which descends from both major coronary arteries. Such a vascular configuration can prevent the dysfunction of right ventricular entire valvular system in case of the occlusion of proximal part of either right coronary artery (RCA) or left coronary artery (LCA). The aim of our study was to determine the vascular pattern of APM blood supply which originates from two main coronary arteries, in the context of the APM and septomarginal trabecula (SMT) topography.
