Case report

A 84-year-old female patient with a history of repeated left and right heart decompensation suffered from severe dyspnea on admission (New York Heart Association functional class III), lower leg edema, bilateral pleural effusions and a stage III chronic kidney disease. Echocardiography showed a moderate to severe recurrent mitral regurgitation after prior successful MitraClip implantation several months ago. In addition a residual ASD with significant left-to-right-shunt and severe tricuspid valve regurgitation with tethered leaflets were found. The left ventricular ejection fraction was reduced (35%). The right ventricular function was not compromised. The systolic pulmonary artery pressure was slightly elevated (40 mmHg). As a result of the heart team discussion the patient was declared as surgically inoperable.
The procedure was performed on October 20, 2015 under general anaesthesia using two- and three-dimensional transesophageal echocardiographic (TEE) (iE 33, Philips Healthcare, Netherland) and fluoroscopy guidance (Axiom Artis Zeefloor AXH 1604, Siemens, Germany). After reaching the left atrium via the preexisting ASD a second MitraClip was fixed in the mitral valve next to the first one (Fig. 1A-B). The MitraClip procedure was performed transfemorally according to the Instructions for Use of the MitraClip system (FDA, USA). After reposition of the steerable guiding catheter in the right atrium a new clip delivery system was introduced into the guiding catheter, but temporarily was left inside. Then the guiding catheter was angulated slightly in “plus” and “anterior” directions to position the guiding catheter vertically to the tricuspid valve. The next step of the maneuver consisted of advancing the MitraClip device into the right atrium, opening both arms, centering and advancing the system into the right ventricle (Fig. 2). By retracting the MitraClip device both leaflets (anterior and septal) were grasped and closed to coapt the tricuspid leaflets. After an effective reduction of tricuspid regurgitation had been achieved, the clip was deployed (Fig. 3A-B). The clip delivery system and guiding catheter were withdrawn. Finally a 25 mm PFO Occluder (St. Jude Medical, USA) was successfully implanted to close the atrial septal defect, using the MitraClip guiding catheter (Fig. 4).
Reconstruction of the two- and three-dimensional transesophageal echocardiographic dataset documented a significant echocardiographic improvement: there was an effective reduction of both mitral regurgitation (vena contracta area at baseline 0.395 cm², after procedure 0.17 cm²) and tricuspid regurgitation (vena contracta area at baseline 1.03 cm², after procedure 0.66 cm²). The atrial septal defect was completely closed by the occluder.
The patient tolerated the simultaneous procedure very well and was discharged 4 days after the implantation.

Discussion

High-risk or inoperable patients with severe mitral and tricuspid regurgitation in combination with ASD are seriously medical challenging. New percutaneous transcatheter methods represent potential technologies to treat these patients with good results. Especially the treatment of the mitral valve with the MitraClip system is well established.
This first-in-human report describes a simultaneous transfemoral transcatheter edge-to-edge repair of both the mitral and tricuspid valve using the MitraClip system completed by occlusion of an atrial septal defect using the PFO Occluder. Two- and three-dimensional transesophageal echocardiography with multiplane imaging and fluoroscopy were necessary for the precise navigation and placement of the MitraClip and PFO Occluder. An effective reduction of mitral and tricuspid regurgitation with successful occlusion of the ASD was achieved.
In conclusion, it has been shown that transfemoral simultaneous (“one approach”) mitral and tricuspid valve repair using the MitraClip system with ASD occlusion could be a feasible, safe and well-tolerated therapy for high-risk or inoperable patients, who are non-responders to conservative medical treatment.
