“…A significant advantage of semi-rigid as well as rigid rings, however, may be apparent in patients with a postischemic V-shape distortion of the mitral ring geometry. 21 In these instances, restoration with rigid or semi-rigid rings appears to be superior as with flexible ones, although robust evidence does not exist. 22 Rigid rings maintain their oval shape entirely during the cardiac cycle, whereas semi-rigid rings have an at least slight tendency to adapt to the natural configural changes of the native ring during systole and diastole.…”

Not all currently available annuloplasty rings are ideal scaffolds for THV placement. It appears that a more proper fit can be achieved with semi-rigid rings than with rigid ones. Note that 23 mm THV appeared to be too small for an adequate anchoring in even the smallest available ring. Thus, 26 mm as well as 29 mm THV fit properly in ring sizes between 28 and 34 mm. Surgeons may consider to choose from those ring brands and sizes which allow for good placement of a THV in view of possible valve degeneration in the later course.

“…The pathophysiology of chronic ischemic mitral regurgitation (CIMR) is complex and its treatment is challenging, burdened by a high rate of mitral regurgitation (MR) recurrence secondary to continuous adverse left ventricular remodeling . The main pathophysiological factor of CIMR is the outward displacement of papillary muscles (PM) leading to leaflet tethering .…”

Papillary muscle intervention vs mitral ring annuloplasty in ischemic mitral regurgitation

Background and Aims The main pathophysiological factor of chronic ischemic mitral regurgitation (MR) is the outward displacement of the papillary muscles (PMs) leading to leaflet tethering. For this reason, papillary muscle intervention (PMI) in combination with mitral ring annuloplasty (MRA) has recently been introduced into clinical practice to correct this displacement, and to reduce the recurrence of regurgitation. Methods A meta‐analysis was conducted comparing the outcomes of PMI and MRA performed in combination vs MRA performed alone, in terms of MR recurrence and left ventricular reverse remodeling (LVRR). A meta‐regression was carried out to investigate the impact of the type of PMI procedure on the outcomes. Results MR recurrence in patients undergoing both PMI and MRA was lower than in those who only had MRA (log incidence rate ratio, −0.66; lower‐upper limits, −1.13 to 0.20; I2 = 0.0%; p = .44; Egger's test: intercept 0.35 [−0.78 to 1.51]; p = .42). The group with both PMI and MRA and that with only MRA showed a slightly higher reduction in left ventricular diameters (−5.94%; −8.75% to 3.13%,). However, in both groups, LVRR was <10%. No difference was detected between PM relocation/repositioning and papillary muscle approximation in terms of LVRR (p = .33). Conclusions Using PMI and MRA together has a lower MR recurrence than using MRA alone. No significant LVRR was observed between the two groups nor between the PMI techniques employed.
