Abstract
Objective
The study aimed to compare the clinical outcomes of simplified linear
plication and classic patch plasty in patients with left ventricular
aneurysm (LVA).
Methods
We retrospectively reviewed 282 patients undergoing LVA repair between 2006
and 2016. After propensity score matching, 45 pairs of patients receiving
LVA surgery were divided into either a patch group (on-pump endoventricular
patch plasty) or a plication group (off-pump linear plication). Then, their
early surgical outcomes and long-term survival were compared in two matched
groups.
Results
The heart function improvement at discharge was similar in the two matched
groups, while patients in the patch group more commonly suffered from low
cardiac output syndrome (P=0.042) with higher proportion of
intra-aortic balloon pumping assistance (P=0.034) than
patients in the plication group. Compared with patients in the patch group,
the patients in the plication group had shorter recovery times, regarding to
mechanical ventilation, intensive care unit stay, and hospital stay
(P<0.001, P<0.001, and
P=0.001, respectively). No significant difference was
found in the long-term survival (P=0.62).
Conclusions
Off-pump linear plication presented acceptable results in terms of early
outcomes and long-term survival. For high-risk patients, the simplified LVA
repair technique may be an option.
