Long-term Follow-Up:
During the follow-up period, we collected echocardiographic findings, performed on our study population within 3 years after surgery. They demonstrated 4 patients in MVRe and no patient in MVRp had severe MVR (2 patients with sole regurgitation and 2 patients with annular ring dislocation) within 3 years after surgery (p=0.09). A valve replacement was performed on one patient and the other 3 patients underwent valve re-repair; one patient is currently listed for heart transplant due to preoperatively known cardiomyopathy.
We observed altogether eight patients who required redo surgery within the follow-up period (Tab 4). A valve replacement was performed in five cases. Only one patient developed endocarditis after 6 months of MV replacement. This was treated operatively with a re-replacement.
Overall survival of the total population after 5 years was 85.1%. Survival in MVRe was 90.06% after 5 years and 79.54% in MVRp (p = 0.04) (Fig 1).
