Definition: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Input: Abstract: The importance of the once-obscure right ventricle is becoming evident. Even in disorders that primarily affect the left ventricle, the once-considered-passive conduit has proved essential for maintenance of normal cardiac output. In coronary artery disease, the function of the right ventricle is affected by both its circulation and the after-load placed on it by dysfunction of the left ventricle. In congestive heart failure, right ventricular function relates to functional capacity, whereas left ventricular function does not, and right ventricular ejection fraction is a useful prognostic guide in these patients. In mitral and aortic valvular disease, the role of the right ventricle is only now becoming evident, and the precise interplay of all factors has yet to be explained. In systemic hypertension, it is likely that the pulmonary circulation is affected by the same humoral factors that elevate systemic pressures. 
 Which is the apt title for the abstract? option1: Effect of the left ventricle on the right ventricle. option2: Dietary habits in patients with dumping syndrome-like symptoms after proximal selective vagotomy.
Output:
Effect of the left ventricle on the right ventricle.
