“…Coronary ostia obstruction is a rare but life-threatening complication of TAVR. Persistent hypotension, typical ST-segment elevation, and ventricular fibrillation are common presentations of coronary ostial obstruction after THV deployment ( 28 ). Therefore, the risk of coronary ostia obstruction is an important issue in the preoperative evaluation of TAVR procedures.…”

“…Therefore, the risk of coronary ostia obstruction is an important issue in the preoperative evaluation of TAVR procedures. The risk factors for coronary ostia obstruction in patients having TAVR with regular TAV have been reported and include smaller sinus of Valsalva, low coronary height, and bulky valve leaflet calcification on CT scans ( 28 – 30 ). These principles can also be used to assess the risk of coronary ostia obstruction in QAV.…”

BackgroundQuadricuspid aortic valve (QAV) is a rare congenital malformation that can present with aortic regurgitation or aortic stenosis (AS)), requiring surgical treatment. Transcatheter aortic valve replacement (TAVR) is an alternative treatment for older patients and its prognosis for QAV therapy remains challenging. We sought to examine our early experience with TAVR in patients with QAV.Materials and methodsProspectively collected data were retrospectively reviewed in patients with QAV undergoing TAVR in our institution.ResultsFive patients with QAV and AR or AS were treated with TAVR between January 2016 and January 2022. The mean age was 73.8 years (range 69–82 years), and the median Society of Thoracic Surgeons score was 7.51% (range 2.668–18.138%). Two patients had type B and three had either type A, D, or F according to the Hurwitz and Roberts classification for QAV. Four patients with pure aortic regurgitation underwent transapical TAVR using the J-Valve system, and the patient with severe AS underwent transfemoral TAVR using the Venus-A system. Procedural success was achieved in all five patients. Trivial paravalvular leak was only detected in one case after the procedure, and one patient received a permanent pacemaker due to high-degree atrioventricular block three days later. The median follow-up period was 18 (12–56) months. After discharge, no deaths occurred during the 1 year follow-up. All patients improved by ≥1 New York Heart Association functional class at 30 days; four patients were in functional class ≤II later in the follow-up period. All patients’ heart failure symptoms improved considerably.ConclusionOur early experience with TAVR in QAV demonstrates these procedures to be feasible with acceptable early results. Further follow-up is necessary to determine the long-term outcomes of this modality.Clinical trial registration[ClinicalTrials.gov], identifier [NCT02917980].

“…Usually a multimodality approach is recommended for evaluation of calcification, the characteristics of the valve itself and the aortic root. There are excellent reviews discussing imaging far beyond the scope of this overview ( Salemi and Worku, 2017 ; Pawade et al, 2019 ; Francone et al, 2020 ; Ternacle and Clavel, 2020 ; Tzolos et al, 2020 ; Fletcher et al, 2021 ).…”

Aortic valve stenosis secondary to aortic valve calcification is the most common valve disease in the Western world. Calcification is a result of pathological proliferation and osteogenic differentiation of resident valve interstitial cells. To develop non-surgical treatments, the molecular and cellular mechanisms of pathological calcification must be revealed. In the current overview, we present methods for evaluation of calcification in different ex vivo, in vitro and in vivo situations including imaging in patients. The latter include echocardiography, scanning with computed tomography and magnetic resonance imaging. Particular emphasis is on translational studies of calcific aortic valve stenosis with a special focus on cell culture using human primary cell cultures. Such models are widely used and suitable for screening of drugs against calcification. Animal models are presented, but there is no animal model that faithfully mimics human calcific aortic valve disease. A model of experimentally induced calcification in whole porcine aortic valve leaflets ex vivo is also included. Finally, miscellaneous methods and aspects of aortic valve calcification, such as, for instance, biomarkers are presented.

Transcatheter aortic valve replacement (TAVR) has been shown to be a valid treatment option for patients with significant symptomatic aortic valve stenosis and high surgical risk. Rupture of the aortic root is a rare but life-threatening complication that occurs in approximately 1% of procedures and usually manifests as an acute complication at the time of valve implantation; however, physicians should be aware of a potentially subacute onset, since early recognition and immediate management are crucial. While many potential causes have been described, it is currently unknown which combinations will lead to its occurrence. Accurate preprocedural assessment of the aortic annulus and its adjacent structures as well as adequate sizing of the prosthetic valve are important steps to prevent rupture of the device landing zone.
