Comparative StudyProlonged abnormalities of LV regional wall motion after normal reperfusion in patients with preoperative cardiogenic shock.
The purpose of this clinical study was to (1) evaluate mortality rates after surgical interventions for patients in cardiogenic shock (CS) secondary to acute coronary occlusion, acute ventricular septal defect (VSD) or acute valvular heart disease, (2) determine the pre-operative regional wall motion, and (3) ascertain the recovery of preoperative regional wall motion abnormalities after surgical intervention. The hospital records of twenty-five consecutive patients in CS were reviewed retrospectively. Regional wall motion was assessed preoperatively by ventriculography and postoperatively by 2D echocardiography (Sonotron Kardio VUE 60) after 1 and 3 days and at the day of discharge from the surgical ward (7-10 days). ⋯ Of 10 dyskinetic segments before surgical intervention, 5 were akinetic postoperatively, and only 5 developed slight hypokinetic contractions. The overall hypokinetic regions were not different as compared to the preoperative data (36.4% vs 39.4%). The normokinetic segments increased from 9.1% to 33.% (p less than 0.05).
