Severe Aortic Regurgitation

Background: The presence of a bicuspid aortic valve (BAV) might be associated with a progressive dilatation of the aortic root and ascending aorta. However, involvement of the aortic arch and descending aorta has not yet been elucidated. Patients and methods: Magnetic resonance angiography (MRA) was used to assess the diameter of the ascending aorta, aortic arch, and descending aorta in 28 patients with bicuspid aortic valves (mean age 30 ± 9 years). Results: Patients with BAV, but without significant aortic stenosis or regurgitation (n = 10, mean age 27 ± 8 years, n.s. versus control) were compared with controls (n = 13, mean age 33 ± 10 years). In the BAV-patients, aortic root diameter was 35.1 ± 4.9 mm versus 28.9 ± 4.8 mm in the control group (p < 0.01). The diameter of the ascending aorta was also significantly increased at the level of the pulmonary artery (35.5 ± 5.6 mm versus 27.0 ± 4.8 mm, p < 0.001). BAV-patients with moderate or severe aortic regurgitation (n = 18, mean age 32 ± 9 years, n.s. versus control) had a significant dilatation of the aortic root, ascending aorta at the level of the pulmonary artery (41.7 ± 4.8 mm versus 27.0 ± 4.8 mm in control patients, p < 0.001) and, furthermore, significantly increased diameters of the aortic arch (27.1 ± 5.6 mm versus 21.5 ± 1.8 mm, p < 0.01) and descending aorta (21.8 ± 5.6 mm versus 17.0 ± 5.6 mm, p < 0.01). Conclusions: The whole thoracic aorta is abnormally dilated in patients with BAV, particularly in patients with moderate/severe aortic regurgitation. The maximum dilatation occurs in the ascending aorta at the level of the pulmonary artery. Thus, we suggest evaluation of the entire thoracic aorta in patients with BAV.

Aortic Dissection Type A

Background: The choice of arterial inflow for acute Stanford type A aortic dissection repair remains controversial. The axillary artery should be considered as first choice for cannulation, but this technique is time-consuming. The ascending aortic cannulation provides antegrade perfusion and can be performed rapidly but there are several concerns such as aortic rupture, extension of dissection, and false lumen cannulation. Objective: To compare the establishment time of cardiopulmonary bypass (CPB) and postoperative outcomes of the two cannulation techniques that provide antegrade perfusion, which was direct true lumen cannulation on the dissected ascending aorta using epiaortic ultrasound-guided and axillary artery cannulation in Siriraj Hospital. Materials and Methods: The authors retrospectively reviewed all the 30 cases of acute aortic dissection type A using two different cannulation methods performed between February 2011 and May 2017. Direct true lumen ascending aortic cannulation was performed using the epiaortic ultrasound-guide with Seldinger technique in 12 patients, and axillary artery cannulation was performed in 18 patients. Results: The direct true lumen ascending aortic cannulation was safely performed in all patients. None of them had aortic rupture. Skin incision to CPB time was significantly faster in the epiaortic ultrasound-guided ascending aortic cannulation group at 29±8 versus 49±14 minutes (p<0.001). The 30-day mortality and postoperative adverse events, such as ischemic stroke, acute kidney injury, visceral organ and limb malperfusion showed no statistically significant difference from the axillary artery cannulation method. Conclusion: Epiaortic ultrasound-guided true lumen cannulation of ascending aorta in the treatment of acute aortic dissection type A is safe and feasible. Skin incision to CPB time can be performed faster and provided good outcome compared to the axillary artery cannulation technique.

In blood vessels situated just after the heart, an irregular blood flow occurs due to some specific structural elements of the tunica media. The current paper describes the histological aspects of some post-cardiac arterial sections in lamb. The tissue samples were collected from five 30 days old male lambs (Țurcană breed). Histological specimens from different regions of the aorta were harvested (i.e., the ascending aorta, aortic arch, thoracic and abdominal regions of the descending aorta). From the specified regions, small pieces (cca. 0.5 cm) were fixed in neutral 10% buffered formalin. The tissues were subsequently embedded in paraffin wax, sectioned at 5 μm, and stained with Goldner’s trichrome and Verhoeff methods. Tissue analysis was performed using an Olympus system for image acquisition and analysis. Histological appearance of the assessed segments of the aorta in lamb is unusual. Major changes occur in tunica media of the aorta. In the ascending aorta, aortic arch and thoracic regions of the aorta, the histological outline is somewhat the same. The internal region of the media possesses the typical lamellar arrangement. Concerning the outer part of tunica media, the smooth muscle has a tendency to form bundles of various sizes. The muscle islands are not present in the media of abdominal region of the aorta, which exhibits the classic pattern of elastic arteries.

Ascending thoracic aortic aneurysms are rare in childhood and typically are seen in the setting of connective tissue defect syndromes. These aneurysms may lead to rupture, dissection, or valvular insufficiency, so root replacement is recommended. Here, we present a 17-month-old girl who presented with fever, cough, and pericardial effusion. Initially, we suspected this could be a COVID-19 case, so a nasopharyngeal swap was performed. An ascending aorta aneurysm involving the aortic arch was confirmed by echo, and urgent ascending aorta and arch replacement were done by utilizing the descending aorta as a new arch. The final diagnosis came with cutis laxa syndrome. In similar cases, good outcomes can be achieved with accurate diagnosis and appropriate surgical management.
