Short and mid-term effects of modified release technique in rheumatic mitral valve repair

To regain optimal mean transvalvular pressure gradients and end-diastolic peak flow velocity, the modified release technique combined peeling in the anterior leaflet and separated the shortened chordal.

| description | Abstract Objective Repair or replacement remains debatable in rheumatic heart disease. To regain optimal mean transvalvular pressure gradients and end-diastolic peak flow velocity, the modified release technique combined peeling in the anterior leaflet and separated the shortened chordal. In the end, the short and mid-term outcomes of the modified release technique were evaluated. Methods We retrospectively analyzed a series of 128 patients with rheumatic mitral stenosis, from January 2018 to July 2021 in our center. All patients undergoing mitral valve repair were using the modified release technique. The effect of mitral valve repair was evaluated by intraoperative transesophageal echocardiography and postoperative transthoracic echocardiography. Results All the 128 patients successfully repaired the mitral valve. The intraoperative transesophageal echocardiography showed trivial or mild regurgitation. The aortic valve was repaired without obvious regurgitation in 12 cases, 5 cases received an aortic valve replacement, 89 cases underwent tricuspid annuloplasty. There were no blood transfusions in most patients, no deaths nor complications during peri-operation, also, no deaths and adverse events were observed during the follow-up period from 3 to 42 months. During the follow-up, 122 cases had no mitral valve regurgitation and 2 cases of moderate regurgitation, 4 cases of mild to moderate regurgitation. The mean peak flow velocity was 1.2 ± 0.3 m / s, no new-onset stenosis occurred. Conclusion Modified release technique is safe and feasible. Its durability is acceptable in the short and mid-term, with no new-onset stenosis during the follow-up. |
