“…We compared the results to the currently available literature on isolated mitral valve surgery either minimally invasively or through full sternotomy [1,2,4,[8][9][10][11][12][13][14][15][16][17][18][19]. Mortality rates reported were anywhere between 0.2 for elective mitral valve repair [19] to 11.6% for valve replacement [9] versus an observed mortality rate of 1.4% in the current analysis including valve replacement, combined and reoperative cases.…”

“…(Ann Thorac Surg 2015;100:1334-9) Ó 2015 by The Society of Thoracic Surgeons D espite excellent operative results in mitral valve surgery using standard sternotomy [1], a gradual interest has emerged to limit the invasiveness of the procedure. As such, minimally invasive mitral valve surgery (MIMVS) was developed in the late 1990s [2].…”

Background. Some controversy exists regarding the safety of endoaortic balloon clamping in minimal access isolated mitral valve surgery (MIMVS). The aim of this European multicenter study was to analyze the results in 10 experienced centers and compare the outcomes with published data.Methods. The most recent 50 consecutive MIMVS cases from10 European surgeons who had performed at least 100 procedures were prospectively collected and retrospectively analyzed. All procedures were performed through right minithoracotomy with femoral cannulation and endoaortic balloon occlusion. In-hospital and 30-day outcomes were studied. Mortality and stroke rates were compared with published median sternotomy and MIMVS outcomes.Results. Mean age was 63.2 ± 12.5 years, 289 (57.8%) were male, mean logistic European system for cardiac operative risk evaluation was 6.1 ± 6.2, and 53 (10.6%) procedures had cardiac reoperations. Concomitant procedures were performed in 126 (25.9%) cases. Three patients (0.6%) required conversion to full sternotomy. Ten patients (2.0%) necessitated endoaortic balloon clamping conversion (8 to external clamping), and

“…Despite the established role of cardiac surgery in mitral valve repair [3], several percutaneous techniques are being developed to treat MR [4][5][6]. Since the operator has no ability to directly visualise the operated area, different imaging modalities, such as computed tomography (CT), magnetic resonance imaging (MRI), and especially echocardiography, play a significant role in the execution of percutaneous procedures [7].…”

A b s t r a c tBackground: Structural heart disease, including valvular disease as well as congenital defects, causes important alterations in heart anatomy. As a result, individualised planning for both surgical and percutaneous procedures is crucial for procedural optimisation. Three dimensional (3D) rapid prototyping techniques are being utilised to aid operators in planning structural heart procedures. Aim:We intend to provide a description of 3D printing as a clinically applicable heart modelling technology for the planning of percutaneous structural heart procedures as well as to report our first clinical use of a 3D printed patient-specific heart model in preparation for a percutaneous mitral annuloplasty using the Mitralign percutaneous annuloplasty system. Methods:Retrospectively gated, contrast enhanced, multi-slice computed tomography (MSCT) scans were obtained. MSCT DICOM data was analysed using software that creates 3D surface files of the blood volume of specific regions of interest in the heart. The surface files are rendered using a software package that creates a solid model that can be printed using commercially available stereolithography machines. Results:The technique of direct percutaneous mitral annuloplasty requires advancement of a guiding catheter through the aorta, into the left ventricle, and requires the positioning of the tip of the catheter between the papillary muscles in close proximity to the mitral annulus. The 3D heart model was used to create a procedural plan to optimise potential device implantation. The size of the deflectable guiding catheter was selected on the basis of the patient's heart model. Target locations for annulus crossing wires were evaluated pre-procedurally using the individual patient's 3D heart model. In addition, the ability to position the Bident Catheter at the appropriate locations under the mitral annulus as well as the manoeuvrability between the papillary muscles were analysed on the heart model, enabling safe completion of the procedure, which resulted in a significant reduction in mitral regurgitation.Conclusions: 3D printing is a helpful tool in individualised planning for percutaneous structural interventions. Future studies are warranted to assess its role in preparing for percutaneous and surgical heart procedures.
