OBJECTIVE: We aim to show the step-by-step surgical technique of mitral valve re-repair by means of a repeated right anterior minithoracotomy in a case of a procedure-related early mitral valve repair failure due to left ventricular positive remodeling and chordal pseudo-elongation.
METHODS: The patient was readdressed to our institution for an early severe mitral valve regurgitation, less than a year after performing a right minithoracotomy mitral valve repair (42-mm annular ring implantation, P2 triangular resection, and P2 neochord positioning). The mechanism was attributed to a positive left ventricle remodeling and neochordal pseudo-elongation. Therefore, we decided to perform a mitral valve re-repair in a redo minimally invasive cardiac surgery. We describe in a video-guided step-by-step fashion the surgical procedure, from the reopening of the right anterior minithoracotomy to the surgical strategy chosen to address the re-repair, guided by the mechanism of the previous repair failure.
RESULTS: We replaced the previously implanted ring with a smaller one and positioned a new polytetrafluoroethylene 4-0 neochord at the P2 level. The patient was discharged home on the fifth postoperative day after an uneventful hospital stay. Predischarge echocardiogram demonstrated undetectable residual mitral valve regurgitation. At 3-month follow-up, echocardiographic and clinical data were encouraging. At 9-month follow-up, the patient endorsed no recurrence of cardiologic symptoms.
CONCLUSIONS: Redo minimally invasive cardiac surgery is a viable option even in case of a mitral valve re-repair due to previous repair failure, especially when procedure related in degenerative mitral disease. Combining the benefits of mitral valve re-repair with those of a minimally invasive surgery may optimize short-term and long-term outcomes.
