Follow-up and outcomes of patients undergoing mitral repair in a centre where the cardiology service assumes immediate postoperative care

In patients with mitral regurgitation (MR) due to prolapse, when surgical treatment is indicated, valve repair (VR) is the treatment of choice. However, results are heterogeneous between centres.

In the present study, we evaluated the short-, medium- and long-term prognosis in terms of cardiovascular (CV) events and complications in patients undergoing RepM in our centre, where the cardiology service assumes the immediate postoperative care of patients in the Coronary Unit.

We conducted a longitudinal observational study at our centre.

We have a cohort of 130 patients who underwent mitral valve repair in the last 11 years for severe MI.

We conducted a follow-up of this sample, assessing intensive care unit stay and immediate postoperative complications, as well as the occurrence of long-term CV events, which we defined as: CV mortality, heart failure (HF), stroke and rate of conversion to mitral valve replacement.

The study included 130 patients, mean age 61 years, standard deviation (SD) 12, with 67% women. The mean follow-up time was 7 years.

The mean ICU stay was 4.3 days, with a surgical complication rate of 15%, mainly due to post-surgical bleeding. We recorded only one death resulting from the procedure (iatrogenic pulmonary artery tear).

In terms of long-term complications, the CV mortality rate was 2% of all patients (3 deaths). The incidence of stroke was 4%. Only 9% of patients were admitted during follow-up for HF. The rate of conversion to valve replacement surgery was only 4% of all patients.

In our centre, mitral valve repair in mitral valve prolapse MI has excellent short-term results, with a low ICU stay and only one death attributable to surgery.

Long-term results are also good, with high follow-up survival and long durability of the repair.

It is very important to know the surgical and postoperative results, in order to optimise patient selection when indicating surgery.
