[Early complications and changes of left ventricular geometry and volume following two types of ventricular reconstruction: compression of scar zone and modified Dor aneurysmectomy].
The aim of the study was to evaluate early complication rate and changes of left ventricular geometry and function after two types of left ventricular reconstruction surgery.


METHODS
The study included 54 patients with ischemic heart disease and left ventricular aneurysm, who underwent coronary artery bypass grafting and left ventricular reconstruction surgery: I group (31 patients) underwent modified Dor aneurysmectomy and II group (23 patients) underwent infarcted wall compression. The study protocol included operative data, early postoperative complications and evaluation of left ventricular function 10(th)-14(th) day after surgery.


RESULTS
Early complication rate had tendency to be higher in I group. Among patients with left ventricular ejection fraction <20%, in I group all 6 patients died, including 5 patients who underwent aneurysmectomy combined with mitral and tricuspid anuloplasty and 2 patients who underwent both apical aneurysmectomy and posterior wall compression, in II group - 1 of 3 patients died. Early changes of left ventricular geometry in I group included decrease in left ventricular diameter, volume, mass, as well as reduction of short axis of left atrium, in II group - decrease in left ventricular diameter, mass and both axis of left atrium. Left ventricular ejection fraction had tendency to increase in both groups: in 41.9% of patients in I group and in 56.5% in II group.


CONCLUSIONS
Following different types of left ventricular reconstruction surgery early postoperative complications rate did not differ, except higher mortality rate in patients with left ventricular ejection fraction <20%, who underwent modified Dor aneurysmectomy combined with other surgical procedures. Early changes of left ventricular geometry and volume differed between patients who underwent different types of left ventricular reconstruction.
