Linea Parasternalis Lower Border: Obliquely: From Cartilage of 5th rib to 5th intercostal space. Left Border: 5th intercostal space to the level of the 4th rib. Openings op the heart: Atrioventricular Openings: 3rd rib to the 6th sternal junction. Aortic and Pulmonary openings: 3rd sternal junction to the 4th sternal junction Topography of the valves of the heart: Aortic and Pulmonary Valve: 2nd intercostal Space Tricuspid and Bicuspid Valve: 5th intercostal space. Syntopia of the heart: Anteriorly: Behind Sternum Posteriorly: Oesophagus Laterally: Pleura Inferiorly: Diaphragm Superiorly: Great Blood vessels Sources used in this video: Memorix Anatomy 2nd Edition by Hudák Radovan (Author), Kachlík David (Author), Volný Ondřej (Author) Biorender University notes and lectures
