Methods: Between April 2006 and March 2015, 18 patients with dyskinetic (dyskinetic group) and 12 patients with akinetic (akinetic group) postinfarction LV anterior aneurysm receiving SVR with the Dor procedure at Chinese People's Liberation Army General Hospital were enrolled in this study.
sup][6],[10] A marked improvement in LV volume and pump function early after SVR with the Dor procedure has been reported in patients with postinfarction LV anterior aneurysm.
From April 2006 to March 2015, a total of 76 patients with postinfarction LV anterior aneurysm underwent SVR with the Dor procedure at Chinese PLA General Hospital.
For the Dor procedure, the rebuilding of the LV cavity is initiated using a continuous suture placed at the junction of the scar and normal myocardium, and the suture is tightened at the theoretical diastolic capacity of the patient LV (50–60 ml/m [sup]2) to attain a normal size of the LV.
The Dor procedure for the repair of aneurysm depends on the identification of the junction between scar and normal myocardium,[sup][17] which is not always definitive and cannot be detected easily in patients with akinetic aneurysm,[sup][18] and therefore an excess of scarred LV may be salvaged; or (2) progressive LV remodeling.
Recently, many articles attested to the superiority of adding either a Toupet or a Dor procedure to the myotomy.
However, recent studies have indicated that a Heller myotomy and Dor procedure should be the treatment of choice for achalasia (14,17,27) because it is associated with good relief of dysphagia and a low rate of GOR as determined by 24-hour pH monitoring.
UNMC has pioneered such progressive projects as developing revolutionary surgical tools such as the Intuitool for laparoscopic surgery, airing live surgical web casts, and performing innovative new heart procedures such as the Dor procedure, which targets patients with advanced heart failure.
