Three-dimensional virtual and printed models improve preoperative planning and promote patient-safety in complex congenital and pediatric cardiac surgery.

Conclusion: 3D-printed models can contribute to the safety of complex congenital cardiac surgeries in selected scenarios. Besides their numerous benefits, currently inadequate financial coverage of the extra time/labour and material/machinery by insurance is mentioned as a major drawback.

Conclusion: The 3D printing allowed the construction of aortic diseases realistic prototypes, offering a 3D view from the two-dimensional image of computed tomography (CT) angiography, allowing better surgical planning and surgeon training in the specific case beforehand.

Conclusion Simultaneous application of the David and FET procedure in patients with acute aortic dissection is safe and feasible in experienced hands as compared with standard aortic root replacement plus FET. The mid-term outcomes are encouraging and noninferior to conventional surgery results.

Abstract Pulmonary valve diseases include the different degrees of aortic stenosis or congenital defects in children or adults. Valve repair or replacement surgery is commonly performed to relieve valvular dysfunction and improve the significant flow regurgitation in the aortic valve and the pulmonary valve. However, commercial valve stents and valved conduits are sometimes not available for children or patients with special conditions. The handmade trileaflet valve design has been used with different range of diameters for patch-valved conduit reconstruction. Thus, we propose a multiple regression model, as a gen...

Abstract A hybrid suite is an operating theater with imaging equipment equivalent to that used in an angiography suite with computed tomography (CT) and magnetic resonance imaging (MRI). They are often situated outside the operating room area and typically serve as multifunctional rooms designed to support a variety of catheter-based endovascular procedures and open surgery to be performed in the same location. The possibility to perform these in the same location facilitates the combination of both approaches to so-called hybrid procedures. Typical clinical applications of hybrid suites are cardiac, thoracic...

Authors: Owais T, El Garhy M, Fuchs J, Disha K, Elkaffas S, Breuer M, Lauer B, Kuntze T Abstract BACKGROUND: Left ventricular (LV) perforation is one of the rare and most serious complications of transcatheter aortic valve implantation (TAVI). The study aim was to determine the pathophysiological factors associated with this serious complication. METHODS: A retrospective study was conducted of pathophysiological factors shown in echocardiograms and computed tomography angiograms performed preoperatively in patients who developed LV perforation during transfemoral TAVI (study group) with regards to anatomic and ...

A 59‐year‐old female with Tetralogy of Fallot had a previous complete repair with RVOT patch enlargement. She developed subsequent severe symptomatic (NYHA III) pulmonary regurgitation with severe RV dilatation. She had a concomitant interstitial lung disease secondary to hypersensitivity pneumonitis that precluded her from cardiac surgery. After preprocedural assessment using computed tomography, echocardiography and invasive angiography we decided to implant a 29 mm Edwards Sapien 3 valve without pre‐stenting. The Sapien 3 valve was implanted in a satisfactory position using rapid RV pacing. The valve appeared well...

Abstract Each year, approximately 300,000 heart valve repair or replacement procedures are performed worldwide, including approximately 70,000 aortic valve replacement surgeries in the United States alone. Computational platforms for simulating cardiovascular devices such as prosthetic heart valves promise to improve device design and assist in treatment planning, including patient-specific device selection. This paper describes progress in constructing anatomically and physiologically realistic immersed boundary (IB) models of the dynamics of the aortic root and ascending aorta. This work builds on earlier IB mod...

CONCLUSIONS: Contrast material-enhanced ECG-gated CTA applied after mitral valve repair with Gore-Tex neochordae allows one to obtain satisfactory mitral valve images, especially during mid-systole, and evaluate mid-term results of the surgery in chosen patients. PMID: 28747938 [PubMed]

A 63 year old male was referred by cardiothoracic surgeons for endovascular repair of an aortic coarctation with post-stenotic dilatation (magnetic resonance angiogram; A, asterisk), following bicuspid aortic valve and aortic root repair. He underwent thoracic aortic relining using a 32 –201 mm Zenith Alpha endoprosthesis (Cook Aortic Intervention, Bloomington, IN, USA). Moulding balloon angioplasty of the coarctation increased the 11 mm aortic lumen to>19  mm (computed tomography angiogram; B). Intra-operative intimal disruption of the pre-coarctation aorta emphasised the fragile nature of this are...
