# Progression, Management, and Outcome of Aortic Valve Stenosis in Systemic Sclerosis: A Case Series

## TL;DR

This study examines how aortic valve stenosis progresses in patients with systemic sclerosis and how it is managed, showing that it can develop quickly and requires careful monitoring.

## Contribution

The paper provides new insights into the progression and management of aortic stenosis in systemic sclerosis patients through a case series.

## Key findings

- Severe aortic stenosis developed in 4.3% of systemic sclerosis patients over time.
- The progression rate from moderate to severe aortic stenosis was rapid, with a mean time of 3.2 years.
- Most patients underwent TAVI or SAVR with no major complications, and 80% were alive at follow-up.

## Abstract

Background: In systemic sclerosis (SSc), cardiac involvement is frequent, heterogeneous, and related to a poor prognosis. Due to a longer life expectancy, the development of degenerative aortic stenosis (AS) is not uncommon. The aim of this article is to report the characteristics of AS in SSc, analyzing the rate of progression, the management, and the outcome. Methods: This is a case series conducted at the Department of Cardiology of Monaldi Hospital, Naples, Italy. Results: From January 2007 to December 2022, we analyzed 234 patients with SSc. Ten/234 patients (4.3%) showed severe AS and were included in the analysis (age 75.5 years [IQR 58–84], nine females). Nine had limited and one diffuse SSc. Two patients were in NHYA/WHO II and eight in NYHA/WHO III. All had degenerative three-leaflet AS. Two patients showed severe AS at the first evaluation, and eight developed severe AS during the follow-up, with a time progression from moderate to severe AS of 3.2 ± 1.1 years (progression rate −0.190 ± 0.012 cm2/year for aortic valve area, 8.6 ± 6.1 mmHg/year for mean aortic gradient, 16 ± 7 mmHg/year for peak aortic gradient, and 0.5 ± 0.3 m/s/year for aortic peak velocity). Seven out of 10 patients underwent transcatheter aortic valve implantation (TAVI), one underwent surgical aortic valve replacement (SAVR), one was left untreated, and one was on a waiting list for TAVI. No major complications after TAVI or SAVR occurred. At a mean follow-up of 5.9 ± 3.9 years, eight patients are alive and two died. Conclusion: Severe AS is a relevant cardiac complication of SSc and must be considered in the screening and during the follow-up. Its rapid progression rate may tentatively be due to autoimmunity, degenerative burden, and chronic inflammation.
