Balloon aortic valvuloplasty with simultaneous aortic root injection: a case report of an adjunctive strategy to computed tomography for predicting coronary obstruction in transcatheter aortic valve-in-transcatheter aortic valve procedures.

ABSTRACT:

Background

Computed tomography (CT) assessment is the standard for predicting coronary obstruction (CO) caused by sinus sequestration (SS) during transcatheter aortic valve (TAV) implantation in degenerated TAV (TAV-in-TAV) procedure, but it may not always be accurate. This report describes a prediction method for CO by using balloon aortic valvuloplasty (BAV) during TAV-in-TAV.

Case summary

An 87-year-old woman with a history of balloon-expandable transcatheter heart valve (BE-THV) implantation 7 years prior was admitted with worsening dyspnoea. Echocardiography revealed severe THV deterioration, and CT confirmed calcium proliferation in the THV. Our heart team decided to perform a TAV-in-TAV procedure using a 23-mm BE-THV. Preoperative CT imaging indicated an intermediate
