Primary mitral valve regurgitation (MR) is a comprehensive term that mostly comprises mitral valve prolapse (MVP), while other causes of degenerative MR are often not considered. We describe the echocardiographic characteristics of degenerative nonprolapse mitral regurgitation (DMR) and assess the outcome at medium-term follow-up using the novel average pixel intensity (API) method. Of 126 patients with any nonprolapse DMR were consecutively included. MR was graded according to all guideline-recommended parameters and with the API method. MR flow dynamics in DMR were compared to MVP-MR and functional MR (FMR). DMR is associated with moderate-to-severe calcifications of the mitral valve apparatus, and a low event rate was observed at a mean follow-up of 27months. The API grading method had a higher feasibility (94%) compared to proximal isovelocity surface area (PISA) (60%) method and vena contracta width (VCW) (71%) for assessing MR. The API method was predictive for events. The API method also provides insights into DMR flow dynamics A triphasic pattern was observed with a midsystolic nadir for both API and PISA-EROA, which is similar to the dynamic flow pattern described in FMR, but distinct from holosystolic MVP-MR. Compared to FMR and MVP-MR patients, DMR is less severe and patients with DMR are generally older than MVP-MR patients. DMR is a distinct MR pathology and conveys a relatively low event rate. MR grading was feasible with the API method, and flow dynamics demonstrated a similar triphasic pattern compared to FMR but distinct from holosystolic MVP-MR.
