Abstract

OBJECTIVES:

The aim was to study the change in cardiac index (CI) and pulmonary artery pressure (PAP) by intra-cardiac measurements after surgical ventricular restoration (SVR) in patients with left ventricular aneurysm and symptoms of heart failure. Aspects of functional improvement were analyzed as secondary outcomes.

DESIGN:

Mean PAP and CI were obtained before and 6 months postoperatively in 22 patients who underwent SVR.

RESULTS:

There were no significant changes in CI (2.3 vs. 2.4 L/min/m(2); p=0.91) or mean PAP (22 vs. 22 mmHg; p=0.64) at rest before and six months after surgery. Left ventricular ejection fraction improved from 25 to 38% (p<0.001). Before surgery 15 patients (68%) were in NYHA class III-IV and 6 months after the operation 19 (86%) patients were in NYHA class I-II (p<0.001).

CONCLUSIONS:

Invasive hemodynamic measurements under resting conditions do not correspond well to the significant clinical improvement noted in these patients. Studies during exercise conditions are necessary to further evaluate this procedure.
