Standardized loop technique for mitral valve repair offers good midterm results.
BACKGROUND
We reviewed the midterm results of our approach for mitral valve repair with the use of standardized loops.


METHODS
In a retrospective single-center study, mitral repairs performed between November 2015 and December 2019 with the standardized loop technique were included. Predefined loops of 15 and 25 mm (Gore-Tex) were implanted for posterior or anterior mitral prolapses, respectively. Isolated or concomitant mitral repairs were performed by either a sternotomy or minithoracotomy. Mean follow-up was 25.3 ± 14.7 months.


RESULTS
Among 92 patients operated on for mitral repair during this period, 65 had repair with the standardized loop technique. They were mostly men (73.8%) and the mean age was 65.1 ± 9.7 years. Valve prolapse was mainly posterior (87.7%), and cordal rupture was seen in 81.5% of cases. The procedures were carried out by a minithoracotomy in 49.2% of patients. Isolated mitral repairs represented 63.1% of cases. Crossclamp and bypass times were 102 ± 22.8 min and 144.7 ± 34.9 min, respectively. The mean number of loops implanted was 2.7 ± 0.9. No patient left the operating room with moderate or severe mitral regurgitation. Postoperative morbidity was 18.4% (12 patients) and 30-day mortality was 3.1% (2 patients). Overall 4-year survival and freedom from reoperation for mitral repair failure were 84.4% and 91.7%, respectively.


CONCLUSIONS
The standardized loop technique for mitral repair showed good midterm results. This technique can be valuable in the armamentarium of mitral repairs. Further evaluation is needed for long-term follow-up.
