This technical line drawing illustrates the internal structure of the human heart, including right atrium (RA), right ventricle (RV), left atrium (LA), left ventricle (LV), mitral valve (MV), superior vena cava (SVC), pulmonary artery (PA), and ascending aorta (AA). The diagram also indicates blood flow direction (arrow H) and a device component labeled '20', suggesting a medical implant or surgical intervention context. It originates from a 2012 patent application related to cardiac devices or procedures.

Used in medical education, patent documentation, or clinical device manuals to explain heart anatomy and device placement; targets researchers, clinicians, engineers, and students seeking precise anatomical reference aligned with intellectual property filings.
