Abstract An extensive infection of the native aortic or prosthetic valve beyond the aortic annulus could be complicated with various types and degrees of tissue destruction. The left ventricular–aortic discontinuity resulting from extensive infective endocarditis often necessitates pericardial reconstruction of the left ventricular outflow tract and subsequent aortic root replacement. Furthermore, if the membranous ventricular septum is involved with infective tissue destruction, communication between the left ventricle and right atrium, known as a Gerbode defect, and complete atrioventricular block could occur. Surgical reconstruction of these complex pathologies is challenging, with high mortality and morbidity. Herein, we present a rare case of prosthetic valve endocarditis complicated with both left ventricular–aortic discontinuity and an acquired Gerbode defect. At the time of surgery, left ventricular outflow tract reconstruction and the technically more demanding aortic root replacement were considered inevitable because of extensive tissue destruction. However, we performed circumferential left ventricular outflow tract reconstruction with a xenopericardial patch and supra-annular aortic valve replacement using the Solo Smart bovine pericardial stentless valve as a technically less demanding alternative to aortic root replacement. The postoperative course was uneventful, and the patient is well 1 year postoperatively, without valvular dysfunction and recurrent infection.

Concomitant Factors

The aortic root is the portion of the outflow tract of the left ventricle that includes the aortic leaflets, the aortic annulus, the sinuses of Valsalva and the sinotubular junction. The impairment of one or more of these structures can lead not only to dysfunctions of the root, but also to alterations of the adjacent anatomical sites, such as the ascending aorta. The raise and the progress of the alterations are often related to more concomitant factors, whose separated effect can be difficult to assess. At this purpose computational finite element (FE) models can be a useful tool, given their capability the recreate different scenarios by varying one or more parameters of the model in a controlled fashion.

Abstract The purpose of this study was to assess by multislice computed tomography (MSCT) imaging geometry of the ascending aorta, the aortic root, the aortic annulus and the left ventricle outflow tract (LVOT) in aortic stenosis (AS) patients, to compare aortic root morphology in patients with AS with healthy controls and to evaluate sex differences. Fifty patients with severe AS and 50 age- and gender-matched controls who underwent MSCT were included in the study. The dimensions of the LVOT, the aortic annulus, the aortic root, the ascending aorta, and the volume of the aortic root were retrospectively assessed and a comparison was made between patients with severe tricuspid AS and controls. Patients with tricuspid AS in comparison with controls had smaller dimensions of the sinus of Valsalva resulting in reduction of the aortic root volume, whereas the dimensions of the other structures were comparable. MSCT revealed larger annular, LVOT and the sinus of Valsalva dimensions and the aortic root volume in men than women. Men with AS differed from healthy men only in regard to the dimensions of the sinus of Valsalva, while women showed significant differences also in the LVOT, and the aortic annulus. MSCT showed accurately aortic root remodeling in tricuspid AS patients and indentified sex-dependent differences. Women with tricuspid AS differ from healthy women more than men did. A high degree of the variability in the aortic root dimensions requires further careful research.
