Damus Procedure

|
This was originally described by three people - Damus, Kaye & Stansel and is sometimes known as a DSK procedure. It is used in complex disease when there is obstruction to systemic arterial flow. In this example of mitral atresia the blood flow is from LA to RA and thence to RV. Blood can pass directly to the PA and also through the VSD to the aorta. As the VSD is restrictive (small) there is effective subaortic obstruction. Enlarging the VSD will cause heart block and so this is dealt with by anastomosing the PA end to side to the aorta allowing two routes from the heart into the aorta and relieving the obstruction. Pulmonary flow is achieved initially via a BT shunt with subsequent conversion to the Fontan circulation. |
