INTRODUCTION: The aim of this paper is to systematically review the existing literature reporting on patients recruited during the past twenty years regarding the role of left ventricular (LV) reconstruction in ischemic cardiomyopathy in terms of efficacy and mortality and provide an updated overview of the current evidence.
EVIDENCE ACQUISITION: The PubMed and Cochrane bibliographical databases were thoroughly searched for the following MeSH terms: “ventricular reconstruction” OR ventriculoplasty OR “ventricular aneurysm” OR “ventricular restoration.” Original studies -recruiting patients during the past twenty years- on LV reconstruction surgery in more than five cases and reporting on the associated peri- or postoperative mortality were deemed eligible.
EVIDENCE SYNTHESIS: Twenty-seven studies were included and provided data for 3220 patients with a mean age of 61 years. Angina was present in 66.6% (510/766) of the patients, while nine out of ten (635/699) had a history of myocardial infarction. Average preoperative ejection fraction was 29.9% and end-systolic volume index was 93.6 mL/m2. With respect to complications, low cardiac output syndrome and the need for intra-aortic balloon pump were prevalent in 9.3% (79/850) and 18.8% (334/1773), respectively. Thirty-day mortality was 7.1% (230/3220) and late-mortality (mean follow-up of 36.9 months) was 19.6% (548/2791), while the rate of MACCE was 40.1% (367/915). Five-year mortality was 29% (340/1171).
CONCLUSIONS: Our findings provide a current perspective of the role of LV reconstruction in the treatment of ischemic cardiomyopathy suggesting its benefit in survival. Taking into consideration the existing debate, further studies are required so that a solid conclusion to be made.
