Regarding the prosthetic valve, the CT shows
HALT
Valve underexpansion
Severe paravalvular leak
Regarding the coronary arteries, the CT shows:
Occlusion of the LAD at its proximal segment
Distal thrombotic embolization of the LAD
Unobstructed left coronary system
Based on the CT images, the most probable cause of the patient’s symptoms are
Cardioembolic stroke
Delayed coronary sinus sequestration
Coronary vasospasm
Correct! The correct answers are "Q1: HALT / Q2: Unobstructed left coronary system / Q3: Delayed coronary sinus sequestration".
 
Unobstructed left coronary system (D-E), sinus sequestration by HALT (A-B) with narrow STJ, low sinus, and high position of a supra-annular valve, sinus perfusion through a mild paravalvular leak (C).

 
Good try! The correct answers are "Q1: HALT / Q2: Unobstructed left coronary system / Q3: Delayed coronary sinus sequestration".
 
Unobstructed left coronary system (D-E), sinus sequestration by HALT (A-B) with narrow STJ, low sinus, and high position of a supra-annular valve, sinus perfusion through a mild paravalvular leak (C).
