TI  - Preoperative parameters predicting the postoperative course of endoventricular 
      circular patch plasty.
PG  - 363-8
AB  - It is necessary that preoperative factors predicting the postoperative course be 
      easily and precisely documented. We investigated the preoperative predictors and 
      defined the indications of endoventricular circular patch plasty (EVCPP) in 
      patients with ischemic cardiomyopathy (ICM). Between October 1997 and May 2001, 
      22 patients (19 males and 3 females; mean age 63.4 years, range 50 to 75 years) 
      with ICM underwent EVCPP. Only one patient underwent EVCPP alone. Coronary artery 
      bypass grafting (CABG) associated with EVCPP was performed in 18 patients (82%). 
      Twenty-two patients were divided into two groups according to the outcome after 
      surgery. Group A consists of three patients who died after surgery and two who 
      showed no clinical improvement after surgery. Group B comprises 17 patients who 
      showed clinical improvement in terms of New York Heart Association (NYHA) 
      functional class, freedom from angina or congestive heart failure. The left 
      ventricular systolic dimensions (LVDs) in group A was significantly longer 
      compared with that in group B (p=0.02, 5.8 versus 4.8 cm). They were not 
      statistically different in other variables between the two groups. We analyzed 10 
      preoperative variables which are categorized as crucial predictors of 
      postoperative course. We found statistically significant differences in LVDs 
      greater than or equal to 5.5 cm and fractional shortening (FS) less than or equal 
      to 15% (p=0.0393, p=0.0207) as well as an increased odds ratio (13, 18.6667, 
      respectively) between A and B groups. In the present study, LVDs and FS 
      demonstrated the dimensional alteration of the cardiac basal segment, and 
      identify the degree of contraction in the nonaneurysmal portion of the ventricle 
      which will remain after surgery. Therefore, LVDs and FS indicating the functional 
      reserve of the basal segment of the ventricle after EVCPP may be the most 
      important parameters predicting the postoperative course.
