Transcatheter aortic valve implantation (TAVI) is an established therapy for patients with symptomatic severe aortic stenosis and contraindications for surgical aortic valve replacement or with intermediate and high operative risk in whom the heart team considers that TAVI is the best therapeutic option. Accurate patient selection strongly relates on multimodality imaging consisting mostly of the combination of transthoracic echocardiography and computed tomography. To guide the procedure, fluoroscopy is the mainstay imaging modality. In the follow-up of the patients, transthoracic echocardiography and computed tomography are again the main imaging modalities to use. Cardiovascular magnetic resonance and nuclear imaging have a minimal role in this area.

Background: Transcatheter aortic valve implantation (TAVI) provides an acceptable alternative for aortic valve replacement in the elderly, but needs accurate pre-procedural imaging to optimise intervention. Objectives: To evaluate an alternative manual aortic valve calcification scoring system with computed tomography, for patients undergoing TAVI. We hypothesise a correlation between the Free State aortic valve calcium computed tomography score (FACTS) scoring system, valve plaque density and procedure-related complications. Methods: Twenty patients suitable for TAVI were selected according to standard international guidelines and received multimodality imaging prior to intervention. Images were reviewed by two reviewers who were blinded to each other’s scores. Where large inter-individual score variations existed, retraining was done and scores repeated, using a double-blinded method. Matched scores were included in the final analysis. Rosenhek calcification scores were used as a standard of reference. Results: The study comprised 9 (45%) men and 11 (55%) women, with a median age of 83.5 years. Median EuroSCORE was 15.5. FACTS scores ≥6 were associated with the presence of a paravalvular leak (p = 0.01). Procedure-related complications (left bundle branch block, repositioning of the valve and anaemia) were seen in patients with plaques measuring ≥1000 HU (p = 0.07). Conclusion: The FACTS score and averaged valve plaque HU showed potential for predicting a paravalvular leak and procedure-related complications, and could be valuable in the future for optimising patient selection for TAVI.

Abstract Background Over the last decade, transcatheter treatment of degenerative aortic valve stenosis has been established as an alternative to surgical aortic valve replacement. Late complications of transcatheter treatment of aortic stenosis (AS) are infrequent. Case summary We report an 87-year-old woman treated successfully with 23 mm Sapien 3 transapical transcatheter aortic valve implantation for severe AS. She presented 4 months later with a pulsatile mass in the left breast. After exclusion of other diagnoses, the mass was attributed to a sterile abscess communicating with the pericardial cavity due to post-operative chest infection and pleural effusion. Multimodality imaging helped to define the anatomy of the abscess and the mechanism of the pulsation. Discussion This is the first report of a pulsatile sterile abscess occurring as a complication of transapical aortic valve implantation. Multimodality imaging confirmed that the pulsation was due to extension of the abscess into the pericardial cavity, excluded direct communication with the left ventricle, and facilitated successful non-surgical management.

In recent years, the phenomenon of subclinical leaflet thrombosis (SLT) in patients who have undergone transcatheter aortic valve implantation has become increasingly relevant. Hypo-attenuating leaflet thickening and hypo-attenuation affecting motion diagnosed by CT are the hallmarks of SLT, and their incidence varies depending on the intensity of screening. Whether these phenomena are a surrogate for leaflet thrombosis reducing valve durability and increasing the risk of stroke is still a matter of debate. Uncertainty remains over the optimal antithrombotic therapy after TAVI and the best treatment strategy is still not confirmed. Ongoing and future trials will provide more evidence about the best strategy for the prevention and treatment of SLT.
