Mitral valve disease becomes more prevalent as the population ages. As the number of percutaneous mitral valve interventions expands, obscure clinical scenarios may emerge and challenge conventional treatment algorithms. Strategies for dealing with complex repairs build on prior experience in mitral perivalvular leak repair. Cases using nitinol- and expanded polytetrafluoroethylene-based devices are used to treat mitral regurgitation in cases of focal mitral perforations and leaks between previously placed mitral valve edge-to-edge devices. This review discusses risks and benefits of performing such complex mitral repairs and informs clinicians of the strengths of weaknesses of different occluder devices in the mitral position.
