Aortoventriculoplasty for Obstructive Hypertrophic Cardiomyopathy along with Aortic Stenosis

Cangsong Xiao*, Junhui Wang, Haitao Chi

We ever received the case of a middle-aged man with Aortic valve Stenosis (AS) and severe mid- and apical-ventricular septal hypertrophy in our department. We tried to manage both concerns in one operation. Due to severe AS, Aortic Root Enlargement (ARE) is commonly used for aortic valve replacement to prevent Patient-Prosthetic Mismatch (PPM). Konno-Rastan’s (K-R’s) operation is a common procedure of ARE which can be used to resolve the two complications of AS and obstructive Hypertrophic Cardiomyopathy (HCM). Morrow’s procedure is also a general standard operation for HCM. However, they both only can resolve upper-ventricular septal hypertrophy, which are not the best options for the patient. aortoventriculoplasty, differs from K-R’s and Morrow’s procedure, since it mainly involves dissection of the aorta and pulmonary artery to expand the operation field to the apical-ventricular septum. Until now, few doctors have previously preferred and reported it and we also have less experiences. We successfully relieved the rare obstruction, and completed the AV replacement. The patient was followed up for twenty-two months and he had an uneventful recovery. This was an important attempt of the relatively unfamiliar operation for us. We now believe that aortoventriculoplasty could be considered in similar patients with hypertrophy in the middle and lower ventricular septum regardless of valve lesions.
