Background: To determine the rate of progression of dilation of the aortic root in adults with a bicuspid aortic valve. Methods: We reviewed retrospectively the transthoracic echocardiograms of 50 adults with a bicuspid aortic valve. Each patient had had at least two examinations made 12 months apart. Measurements were taken at four levels: at the basal attachment of the leaflets of the valve within the left ventricular outflow tract, at the widest point of the sinuses of Valsalva, at the sinutubular junction, and in the ascending aorta 1 cm beyond the sinutubular junction. Results: Progressive dilation occurred at all levels, ranging from 0.3 mm/yr at the basal attachment within the left ventricular outflow tract to 1.0 mm/yr, 1 cm beyond sinutubular junction. These rates of dilation were greater than the reported rate of 0.8 mm per decade in the normal population. The rate of dilation found in the ascending aorta 1 cm beyond the sinutubular junction was significantly greater than at the other sites (p = 0.005). The 21 patients with baseline measurements greater than 34 mm had a significantly higher rate of progression (p = 0.007). Sex, age, and the degree of valvar obstruction or regurgitation did not significantly influence the rate of progression of dilation. Conclusion: There is a significantly higher rate of dilation of the aortic root in adults with a bicuspid aortic valve when compared to the normal population. Periodic evaluation of the ascending aorta is essential in these patients, even after replacement of the aortic valve. Other imaging modalities should be considered if the region beyond the sinutubular junction is not well visualized by transthoracic echocardiography.

Radiofrequency ablation is the therapy of choice for the suppression of medically intractable symptomatic ventricular arrhythmias. Here we present the case report of a 50-year-old woman with bicuspid aortic valve (BAV) and symptomatic nonsustained ventricular tachycardia arising from the left ventricular outflow tract (LVOT). The origin of the ventricular arrhythmia was confirmed in the left coronary cusp (LCC) of the BAV. The patient underwent a successful radiofrequency ablation. LCC of a tricuspid aortic valve is a common origin of idiopathic LVOT tachycardia; however, little is known for these types of arrhythmias when located in the cusps of a BAV.

AbstractBackgroundPercutaneous implantation of aortic valve for severe aortic stenosis (AS) in the presence of pedunculated mobile left ventricular outflow tract (LVOT) mass not reported before. In this case report, we address the feasibility of this procedure.Case summaryAn 80-year-old patient who presented with presyncope, transthoracic echocardiogram (TTE), and transoesophageal echocardiography (TOE) revealed severe calcific AS and LVOT mass measuring 2.1*1.5 cm. The patient was turned down for surgery. It was decided that transcatheter aortic valve implantation (TAVI) be performed because the valve compresses the mass against the proximal part of the interventricular septum. The mass peduncle was 1.4 cm, and it was 4 mm away from the annulus. This meant the valve was needed to be deployed 18 mm below the annulus to cover the mass completely. Gentle manipulation and direct valve deployment without preballoon dilation to decrease the possibility of fragment embolization were necessary. Self-expandable core valve deployed as low as possible, after initial deployment, the distance of LVOT covered by the valve measured by TOE 1.66 cm, the whole mass was covered, then the valve was fully deployed. The patient was extubated in the catheterization room; there was no clinical evidence of embolization. The patient was discharged home after 2 days. A follow-up TTE after 6 months showed a well-functioning valve and the LVOT mass then disappeared.DiscussionPedunculated LVOT mass should be resected surgically. In high-risk surgical patients, direct TAVI to compress the mass is feasible in experienced canters. The safety issues need more research and more cases to judge. Transoesophageal echocardiography during the procedure is mandatory to guide the valve position.
