Study Notes
Rastelli Classification
- Type A involves a chordal attachment to the crest of the interventricular septum (IVS).
- Type B features chordal attachment to the papillary muscle located in the right ventricle (RV).
- Type C describes a free-floating leaflet, with attachments to papillary muscles in both the right ventricle and left ventricle, lacking any septal attachment.
Complete Atrioventricular Canal Defect (AVCD)
- Characterized by the presence of an ostium primum defect.
- Involves a non-restrictive inlet ventricular septal defect (VSD).
- Features a common atrioventricular valve, which serves both ventricular chambers.
Transitional/Intermediate AVCD
- Also includes an ostium primum defect.
- Contains a restrictive inlet VSD, which limits blood flow.
- Composed of two distinct atrioventricular valves, differentiating it from complete AVCD.
Partial/Incomplete AVCD
- Defined by the presence of an ostium primum defect.
- Lacks a ventricular septal defect (VSD), distinguishing it from both complete and transitional forms.
