ABSTRACT Background: MitraClip therapy (MCT) is becoming more popular to treat mitral regurgitation (MR)
in high-risk patients. It is, however, expanding to lower risk patients with the idea that mitral valve (MV)
repair can be performed if surgery will be necessary. We report our surgical experience in patients who
underwent MCT and subsequently required MV surgery. Methods: From February 2012 to September 2014,
three patients out of 34 who underwent MCT (8.8%) needed surgery because of lesions resulting in new MR.
Two of them had functional and the third one degenerative MR. Two patients with functional MR underwent
emergency surgery for MV lesions adding a new severe MR, the third one, with degenerative MR, had surgery
377 days after MCT. Results: The MV showed a perforation of the anterior leaflet in one case and P2
completely torn in the second case. MitraClip opening was difficult and caused further injury to the leaflets.
The third case developed a severe MV stenosis. All three patients underwent MV replacement with a tissue
valve. The postoperative course was uneventful and, after a mean of 14 months, all patients are alive and in
NYHA class I or II. Conclusions: The risk of urgent or elective surgery after MCT reduces the possibility of
conservative surgery, as the possibility of valve reconstruction is less likely following the severe clip
implantation-induced tissue damages. doi: 10.1111/jocs.12540 (J Card Surg 2015;30:414–418)
MitraClip (Abbott Laboratories, Abbott Park, IL, USA)
therapy (MCT) for treatment of mitral regurgitation (MR)
has recently been introduced into clinical practice.

In
general, MCT is limited to patients deemed inoperable
or at prohibitive surgical risk.
3,4
There is a trend to
expand the indications to less risky patients as an
alternative to conventional surgical treatment. Studies
reported that surgical options were preserved in most
patients after successful or attempted deployment of a
MitraClip device.

We report our experience in patients undergoing
surgery after MCT to evaluate risks and benefits of this
technology in non-high-risk patients.
PATIENT PROFILE
From February 2012 to September 2014, three out of
34 patients who underwent MCT (8.8%) needed
surgery because of MCT complications The Institutional
Review Board approved the research and waived
patient consent. Table 1 shows the preoperative and
postoperative clinical and echocardiographic data.
Patients were all low risk. All of them refused surgery,
against the suggestions of the Heart Team. The choice
of a tissue valve in the two patients who underwent
emergency surgery was due to their personal
preference.
Case 1
The mitral valve (MV) showed annular dilatation and
restricted movements of both leaflets, with no contra-
indications to repair. The MitraClip was deployed in the
mid-portion of the MV (A2 and P2 segments). However,
the clip remained attached only to the posterior leaflet
