From E‐VITA open plus to E‐VITA NEO and E‐NOVIA

Abstract: The first clinical implantation of the "Essen I prosthesis" took place in 2005, which was then followed by E-Vita open plus. With further advancements E-Vita Neo and E-Novia was introduced. These devices enable the surgeons to perform frozen elephant trunk in zone 0/1 which eventually reduce the incidence of paraplegia, recurrent laryngeal nerve palsy and proximalization of supraaortic arch vessels. E-vita open plus and successors alleviate frozen elephant trunk operations rendering more stable results in promoting positive remodelling of the distal aorta.

Right size matters! The ideal size of hybrid prosthesis in frozen elephant trunk.

Abstract: There is abundant of literature emerging to support the use of the frozen elephant trunk prosthesis, but there is still a lack of clear consensus on the sizing of the hybrid prosthesis. There is a general consensus that the stent should not be oversized in acute aortic dissection and chronic aortic dissection. Some surgeons consider that only the true lumen has to be measured while others argue that the entire diameter of the aorta has to be measured, and a few measure the aorta intraoperatively. In regards to thoracic aortic aneurysm, most surgeons oversize the stent-graft by 10% to 20%. A small device may not provide adequate sealing, whereas a larger device may cause new entry points distally. Hence, an appropriate device has to be selected for the optimal outcome.

Paving the way for E-vita open NEO hybrid prosthesis implantation for complex aortic arch disease in Asia-Pacific.

Abstract: We report first in man implantations of the newly designed Evita-open-NEO hybrid prosthesis for complex aortic arch disease from three different countries in Asia-Pacific including instructions on how to proceed with perioperative coagulation management.

Initiating a New Era of Cardiovascular Diagnosis and Therapy in Acute Aortic Syndromes: The Mainz-Essen Experience (Part I)-Imaging and Biomarkers.

Abstract: Acute aortic syndromes (AAS) encompass a group of life-threatening medical conditions (acute aortic dissection [AAD], intramural hematoma, and penetrating aortic ulcer) with a common pathophysiological pathway. Due to overlapping symptoms and signs with other cardiovascular emergencies, the diagnosis remains challenging resulting in time delays and related increased in-hospital and long-term morbidity and mortality. The Cardiovascular Department of Johannes Gutenberg University in Mainz at West-German Heart Centre in Essen (Germany) first described (in 1984) AAD by transesophageal echocardiography, AAD diagnostic features, and furtherly explored the implementation of "invasive" imaging techniques, namely, intravascular ultrasound and intraluminal phased-array imaging. Furthermore, pioneer studies were undertaken on the biomarker and imaging interplay, namely, D-dimer and F-fluorodeoxyglucose positron emission tomography/computed tomography. We discuss the unique 35-year-long Mainz-Essen experience on the diagnostic and prognostic role of serological and imaging biomarkers in AAS.

Launching the E-vita Open Neo amid COVID-Challenges and strategies.

Abstract: Aortic arch disease commonly involves multiple segments, leading to the needs of multistaged procedures and the intraoperative selective perfusion of arch branches. The total aortic arch replacement with frozen elephant trunk (TAR FET) technique was developed over the past decades. It has become one of the mainstream options with acceptable risk profiles. 1 , 2 , 3 , 4 It could offer a single‐stage treatment in selected arch aneurysm cases and, more importantly, it facilitates second‐stage treatments of descending pathologies with endovascular repair 1 , 2 , 5 and open replacement. 1 , 2 , 6 In October 2020, the E‐vita Neo Open was introduced in Hong Kong as a third commercially available hybrid arch prosthesis. Introducing a new medical device requires multi‐levels of co‐ordination to ensure patient's safety and outcome, especially under the challenges of COVID‐19 with travel restrictions and social distancing, we would like to report the feasibility and importance of virtual proctorship.
