Modified valve-in-valve bailout technique of transcatheter aortic valve replacement in severe aortic regurgitation for valve jumping up to ascending aorta: a case report.
European Heart Journal. Case Reports 2022 August
Background: Aortic regurgitation remains a challenge for transcatheter aortic valve replacement (TAVR), because of the high risk of post-procedural migration or paravalvular leakage resulting from the anatomical and pathophysiological features.
Case summary: A 75-year-old male with symptomatic severe aortic regurgitation underwent transfemoral TAVR due to poor physical condition and a Society of Thoracic Surgeons score of 11.3%. However, complete dislodgement of the valve into the ascending aorta occurred during the operation. We performed a modified valve-in-valve technique by using an ablation catheter (instead of performing urgent surgery), and no post-interventional complications were found during hospitalization. The patient was discharged in a stable condition on postoperative Day 12. At the 6-month follow-up, echocardiography showed trivial paravalvular leakage. The left ventricular ejection fraction further improved from 30 to 48%.
Discussion: The management of valve migration can be troublesome. In this case, we performed a modified valve-in-valve technique by using an ablation catheter without post-interventional complications. This is a novel strategy for the management of emergencies, which could avoid surgical thoracotomy. Our strategy may be an alternative option in some cases of valve jumping up to the ascending aorta.
