“…3D echocardiography is currently becoming prevalent in clinical practice (9). CT and MRI techniques used for 3D reconstruction (10) are emerging as valuable tools in the interventional cardiology (11). These imaging advances allow clinical evaluation more accurate, however, they are just a virtual 3D.…”

Background: The aim of this study was to evaluate the effect of 3-dimensional (3D) printing in treatment of hypertrophic obstructive cardiomyopathy (HOCM) and its roles in doctor-patient communication.Methods: 3D-printed models were constructed preoperatively and postoperatively in seven HOCM patients received surgical treatment. Based on multi-slice computed tomography (CT) images, regions of disorder were segmented using the Mimics 19.0 software (Materialise, Leuven, Belgium). After generating an STL-file (StereoLithography file) with patients' data, the 3D printer (Objet350 Connex3, Stratasys Ltd., USA) created a 3D model. The pre-and post-operative 3D-printed models were used to make the surgical plan preoperatively and evaluate the outcome postoperatively. Meanwhile, a questionnaire was designed for patients and their relatives to learn the effectiveness of the 3D-printed prototypes in the preoperative conversations. Results:The heart anatomies were accurately printed with 3D technology. The 3D-printed prototypes were useful for preoperative evaluation, surgical planning, and practice. Preoperative and postoperative echocardiographic evaluation showed left ventricular outflow tract (LVOT) obstruction was adequately relieved (82.71±31.63 to 14.91±6.89 mmHg, P<0.001), the septal thickness was reduced from 21.57±4.65 to 17.42±5.88 mm (P<0.001), and the SAM disappeared completely after the operation. Patients highly appreciated the role of 3D model in preoperative conversations and the communication score was 9.11±0.38 points.Conclusions: A 3D-printed model is a useful tool in individualized planning for myectomies and represent a useful tool for physician-patient communication.

“…Real-time 3D echocardiography is currently entering mainstream clinical practice [9]. MRI techniques allow for 3D reconstruction [10] and new X-ray-based imaging referred to as 3D rotational angiography and C-arm CT are emerging as valuable tools in the interventional cardiology field [11]. Although these imaging advances permit assessment that is more accurate, and allow for better spatial orientation, there is however only a virtual 3 rd dimension, which is unlikely to represent complex 3D relationships faithfully.…”

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.

“…Flat panel detectors and advances in imaging consist of rotational angiography and 3D imaging that in certain complex cases supports anatomical gratitude (9,10). Imaging for interventions will probably lead to more modalities than ionizing radiation, such as ultrasound and MRI (11,12).…”

Cardiac Catheterization and Intervention in Pediatric Cardiac Disease: A Narrative Review of Current Indications, Techniques, and Complications

Context: In the past 20 to 30 years, the area of pediatric interventional cardiology has had noteworthy development. Technological revolutions have significantly progressed management of cardiovascular disease in both children and adults with congenital heart disease (CHD). This article reviews the current indications, techniques and complications of interventional therapy for CHD. Evidence Acquisition: Training and publications in this field are rare. Overall, 64 article from January 1953 to February 2014 were studied. A total of 26 articles were involved in pediatric evaluation. Results: There have been several catheter-based interventions for congenital heart disease. Percutaneous intervention in pediatric cardiac disease has been established in the past 2 to 3 decades. There are currently devices accepted for percutaneous closure of ASDs, patent ductus arteriosus (PDAs), and muscular ventricular septal defects (VSDs). The period of percutaneous valve implantation is just beginning, and the next few years may bring about advances in miniaturized valve distribution methods to allow insertion in smaller children. Conclusions: Completely prepared catheterization laboratory, surgical holdup, and extracorporeal membrane oxygenation support capabilities must be accessible at any center to achieve interventional cardiac catheterization. Additional understanding of normal history of interventions more than 2 decade post process, novel strategies and methods will certainly lead to an increase in the methods for managing of congenital heart disease.
