Abstract
BACKGROUND

Transcatheter aortic valve replacement (TAVR) is recommended in patients with severe aortic stenosis who have high surgical risk. However, in the pre-existing mechanical mitral valve prosthesis and natural pure aortic regurgitation, TAVR is relatively contraindicated. In this report, we described one case of TAVR with native aortic regurgitation in the presence of mechanical mitral valve prosthesis.

CASE SUMMARY

A 64-year-old man with a medical history of mitral valve replacement had severe dyspnea and was symptomatic even at rest for 3 mo. His echocardiography showed severe native pure aortic regurgitation. His euroscore was 15. A TAVR procedure with an evolut R was planned. A 34 mm evolut R was placed by transesophageal echocardiography. The mitral prosthesis was functioning normally, and mild-moderate paravalvular leakage was evident by transesophageal echocardiography. The patient recovered without any complication. At 1 mo follow up, the patient was well, and no paravalvular leakage was noted.

CONCLUSION

TAVR for pure aortic regurgitation in the presence of prosthetic mitral valve can be a safe procedure.

Core tip: Transcatheter aortic valve replacement (TAVR) is recommended in the treatment of severe aortic stenosis in patients who are at high or prohibitive surgical risk. Several patients with previous mitral valve surgery were reported to have been treated with TAVR. However, TAVR has been performed off-label to treat patients with pure aortic regurgitation due to the absence of calcium for device anchoring. There are few data showing that transfemoral TAVR is feasible and safe for the treatment aortic regurgitation in selected patients. Here, we report one case of transfemoral TAVR for native aortic regurgitation in the setting of a pre-existing mitral prosthesis.
