Abstract

OBJECTIVE In 1996, the Brazilian cardiovascular surgeon, Dr. Randas Batista, introduced a surgical technique called partial left ventriculectomy, where he admitted the possibility of reducing the diameter of the left ventricle through the sectioning of one section of its wall. After the publication of this study, thousands of case reports and procedure analysis have been published, and due to several disappointing results, many doctors and institutions failed to execute it. As the main objective of this study, stands out the search for success cases of ventriculectomy in the last 12 years and if during this period it was achieved some significant development in this procedure that allows obtaining lower mortality rate postoperatively.METHODS Systematic review of indexed scientific literature over the past 12 years and the term "Partial Left Ventriculectomy".RESULTS There has been a considerable number of reported successful cases and highly significant findings in regard to determining the most suitable region for the section, proper selection of the patients indicated to the procedure, including the influence of the coronary artery anatomy in the nomination procedure and the need for preservation of ventricular geometry to ensure better quality of ventricular contractions after the sectioning.CONCLUSION This surgical procedure has been successfully performed, mainly in Japan, improvements in its efficiency were found and the need for a mathematical modeling of the slice to be severed is a prominent factor in many studies.

Highlights

IntroductionHeart problems are responsible for about a third of deaths in the world, so the more we study and understand the structure and functioning of the heart, the greater the chances of obtaining and analyzing new techniques for treatment and prevention of heart disease
Heart problems are responsible for about a third of deaths in the world, so the more we study and understand the structure and functioning of the heart, the greater the chances of obtaining and analyzing new techniques for treatment and prevention of heart disease.Among these diseases, there is the Dilated Cardiomyopathy (DCM), which is a heart muscle disease characterized mainly by left ventricular (LV) dilatation and systolic dysfunction[1,2]
The procedure is based on the knowledge that in DCM occurs the increasing in LV diameter, but it does not occur sufficient increase in muscle mass, and a possible damage repair would be the reduction in ventricle diameter to a value close to what was prior to the injury

Summary

Introduction

Heart problems are responsible for about a third of deaths in the world, so the more we study and understand the structure and functioning of the heart, the greater the chances of obtaining and analyzing new techniques for treatment and prevention of heart disease. Among these diseases, there is the Dilated Cardiomyopathy (DCM), which is a heart muscle disease characterized mainly by left ventricular (LV) dilatation and systolic dysfunction[1,2]. The operation is based physical and mathematically by one of the forms of Laplace’s Law (EQ. 1)
