title: Percutaneous closure of a small posterior mitral paravalvular leak in a patient with coexistent monoleaflet mechanical aortic valve.
abstract: Percutaneous closure of a paravalvular leak is a challenging procedure that often presents with multiple simultaneous hurdles. We report a case of percutaneous retrograde paravalvular leak closure in a patient with a coexistent monoleaflet mechanical aortic valve. The leak was crossed and occluded using a combination of techniques deriving from the coronary and peripheral angioplasty fields.
