Reconstruction of the left Ventricle (Dor Procedure)
In patients who suffered from anterior wall infarction, it happens sometimes that the scar left after infarction dilates during the remodeling process leading to the formation of a left ventricular aneurysm.
This aneurismal part does not contract with the rest of the left ventricle, leading to stagnation of blood in this blind sac and formation of a thrombus.
In addition, the thinning of the ventricular wall in the aneurismal part constitutes a risk of left ventricular perforation. The hemodynamic consequence of the aneurismal dilatation is an increase in wall tension leading to more dilatation (vicious circle).
The heart looses its advantageous elliptical form and takes the disadvantageous spherical form. The Ejection Fraction (the amount of blood ejected from the heart into the aorta during contraction) steadily decrease from a normal value of about 70 % to less than 30 %.
In these cases, together with coronary revascularization, we perform left ventricular reconstruction as described by Prof. Vincent Dor from Monaco. The non-contracting tissues are excised and a Dacron patch is sutured in a way that reduces the size of the left ventricle and restores its advantageous elliptical form.
