Preoperative Planning of Transapical Beating Heart Mitral Valve Repair for Safe Adaptation in Clinical Practice
Conclusions We demonstrate a method to safely start the TOP-MINI program with precise patient selection and preoperative planning, allowing us to determine procedural strategy and assessment of surgical success probability.
Purpose of review Transesophageal echocardiography (TEE) has made its way into the cardiac surgery realm and spurred the development of many interventions. In the domain of minimally invasive cardiac surgery (MICS), TEE has become central to reducing cardiovascular complications. Recent findings Real-time three-dimensional TEE is a key contributor to the safe and precise deployment of the PASCAL mitral valve repair system, which is showing great potential in ongoing studies. The current data on outcomes of transcatheter aortic valve replacement show that preprocedural three-dimensional TEE and multidetector computed t...
Transcatheter aortic root repair (TARR) is still not available because of the complex anatomy. In order to develop future TARR technologies, a human-derived bench test model is required before performing animal tests. For this purpose, we aimed to validate computed tomography (CT)-derived 3D-printed root models for TARR technologies. Four human CT-derived roots were printed using different resins: Visijet M3 Crystal, Photopolymer gel SUP705, Formlabs flexible resin, and Materialise HeartPrint Flex. A stress test was performed using a 26-mm balloon-expandable Sapien valve deployed in aortic position. The too rigid Visijet M...
ConclusionsAscending aortic stent placement for ascending aortic disease is feasible and is associated with favorable aortic remodeling. Despite persistent perfusion to the false lumen in a subset of patients, there is minimal aortic dilation at short-term follow-up with excellent survival.
ConclusionValve ‐sparing partial aortic root repair with the patch and coronary artery bypass grafting for aortic dissection limited to the right coronary sinus of Valsalva were technically feasible and safe.
We report a case of a 57-year-old female with dextrocardia and a solitary kidney. A patch aortoplasty for isthmic aortic coarctation repair was performed 40 years before when she was admitted to our department for dyspnea. Computed tomography scan showed a giant and saccular 10-cm diameter patch false aneurysm. The ascending aortic diameter was 34 mm and the echocardiography confirmed a severe aortic regurgitation of a bicuspid aortic valve. We decid ed to perform a 2-step approach: biologic aortic valve and ascending aorta replacement with total debranching of the epiaortic vessels and thoracic endovascular ane...
We report a case of a female 57 years old with dextrocardia and a solitary kidney.

An 80-year-old man presented 3 years after a mitral valve replacement for mitral insufficiency with a complaint of worsening hemoptysis during the last 1.5 months. A computed tomography scan (Fig 1) to evaluate for malignant disease demonstrated a 0.8×0.7-cm pseudoaneurysm of the ascending aorta, probably related to a previou s cannulation site, which was thought to be the cause of his hemoptysis. He was deemed too high risk for open surgical intervention through redo median sternotomy; therefore, an endovascular approach was sought.
Conclusion: The untreated autologous pericardium functioned well when it was used to create a competent pulmonary valve at short term and midterm. Although it changed in its structure; there was no calcification at 5 years of follow-up. PMID: 31274488 [PubMed - in process]
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.
