الملخص EN

This study was done to assess the results surgery for coronary artery bypass grafting (CABG) after complicated cardiac catheterization and interventional procedures at Queen Alia Heart Institute (QAHI)-King Hussein Medical Centre (KHMC).

Between January 1995 and December 2000, eighty nine patients underwent emergency coronary bypass surgery following either diagnostic or interventional coronary angiography.

The following variables were obtained from the medical records.

Patients characteristics, mode of presentation, extent and severity of coronary artery disease, preoperative clinical and hemodynamic status, preoperative left ventricular function, previous CABG surgery, types of constructed conduits and associated procedures, use of intraoretic balloon pump (IABP), operative outcome and in hospital major cardiac events.

Follow up was obtained on all surviving patients.

Emergency CABG patients tented to be males (79.9 %) more symptomatic (66.4 % in class III and IV) and harboring more left main coronary disease (30 %).

The overall hospital mortality rate was high (13.3 %) compared to the low rate of (4.5 %) in our elective CABG population.

Internal mammary artery (IMA) grafts were used less frequently (36.6 %) compared to (93 %) in our CABG population.

Ten patients (11.2 %) had additional cardiac procedures.

A mean follow up duration of 31 months was available on all surviving 79 and (83 %) were completely asymptomatic.
