The most common congenital heart defect is the bicuspid aortic valve (BAV) occurring with fusion of one of the three-valve commissures. A rarer valvular phenomenon is the unicuspid aortic valve (UAV) which has an estimated prevalence of 0.02% in the adult population. Two morphologic subtypes of UAV exist: the earlier presenting, acommissural UAV and the later appearing unicommissural. To better characterize and manage patients with UAVs, a systematic review of this rare phenomenon was performed. The objective of our study was to conduct a systematic review of adequate case studies involving UAV patients to describe patient characteristics, clinical presentation, management, and common sequela featured there within. The mean age of presentation in this review was 35.6 years. When diagnosing UAV, TEE was the most utilized diagnostic modality (65%) followed by intraoperative diagnosis (17%) discovered with valve repair or incidentally during another procedure. TTE was utilized to diagnose only 7% of the cases reviewed likely owing to the difficulty and inaccuracies in identifying UAV with this method that were previously established by multiple series. Interventional options for UAV are balloon versus surgical valvotomy, aortic valve replacement, Ross procedure and aortic root replacement. They are performed on an individual basis and all cases ultimately require aortic valve replacement (AVR) or Ross procedure (to avoid anticoagulation). aortic root replacement is additionally required if aortic root/ascending aorta diameter exceeds 4.5 cm. In this review, aortic aneurysm (16%) cases resulted in surgical interventions. There may be a need to implant permanent pacemaker (in 3% - 8%) during AVR when calcified UAV has calcification extending into interventricular septum.

BACKGROUND: No retrievable and repositionable second generation transcatheter aortic valve is available in China. Here, we report the first-in-man implantation of the retrievable and repositionable VenusA-Plus valve. METHODS: A 76-year-old patient with symptomatic severe aortic stenosis and high surgical risk(STS 13.8%) was recommended for transcatheter aortic valve replacement(TAVR) by heart valve team. Type 0 bicuspid aortic valve with asymmetric calcification was identified by dual source computed tomography, and the unfavorable anatomies increased the possibility of malposition and paravalvular leakage during TAVR. Therefore, we used the retrievable and repositionable Venus APlus valve for the ***: Transfemoral TAVR was performed under local anesthesia with sedation, and a 26-mm VenusA-Plus valve was successfully implanted. No transvalvular pressure gradient and trace paravalvular leakage were found. CONCLUSION: The successful first-in-man implantation indicates the retrievable and repositionable Venus A-Plus valve is feasible in complicated TAVR cases such as bicuspid aortic valve.

Junctional rhythm is usually seen in the clinic with different *** report a case of bicuspid aortic valve accompa-nied by sinoatrial node *** junctional escape beat could accelerate with physiological needs and provided for the normal needs of daily life when dysfunction of the sinoatrial node occurred,which provides a new way for the treatment of sinoatrial node *** fi ndings could be potentially signifi cant for identifying causes and choos-ing appropriate treatment strategies by using ECG monitoring in the clinic in the future.
