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.

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.

Abstract Background Long-term complications after cardiac transplantation are common and typically include arterial hypertension and coronary allograft vasculopathy. Few studies also suggested that heart transplant recipients have an increased arterial stiffness. Purpose This prospective study aimed to assess the bioelastic properties of the aorta as well as LV function, morphology and structure in children and young adults after cardiac transplantation. Methods CMR studies from 34 patients (median age: 17.1 years, range: 8–24 years) who underwent cardiac transplantation in childhood were analysed. Aortic anatomy and distensibility were assessed at five locations of the thoracic aorta using steady-state free precession cine sequences. Pulse wave velocity (PWV) of the aortic arch and the descending thoracic aorta was measured from 2-dimensional phase contrast images. Size and function of the left atrium and the ventricles were assessed from a stack of short axis slices. Myocardial T1 times were determined using a standard MOLLI sequence. Results Cross-sectional areas of the ascending aorta and the aortic arch tended to be lower in patients compared to controls (ascending aorta 464.5±172.5 mm2 vs. 515.3±186.3 mm2, aortic arch 342.4±113.3 mm2 vs. 376.9±148.5 mm2) whereas cross-sectional areas of the descending aorta tended to be higher (aortic isthmus 283.7±102.1 mm2 vs. 257.9±89.5 mm2, aorta descendens diaphragmal 218.4±75.8 mm2 vs. 214.2±75.0 mm2) and showed a correlation with systolic blood pressure (r=0.33). PWV was higher in the aortic arch (4.8±2.4 m/s vs. 3.6±0.7 m/s). Aortic distensibility was slightly higher at all measuring points in the study population compared to the control group and showed an increase with rising distance from the heart (ascending aorta 10.5±5.8 10–3 mm Hg-1, aortic isthmus 13.1±7.5 10–3 mm Hg-1, descending aorta 16.6±6.8 10–3 mm Hg-1). Biventricular volumes were slightly reduced in the patient group compared to the control group but this was not statistically significant. Only left ventricular mass messured during the systolic phase was higher in the study population compared to the control group (males 55.1 g/m2 vs. 53.0 g/m2, females 46.2 g/m2 vs. 45.2 g/m2). T1 mapping demonstrated increased T1 times in the heart-transplanted group compared to published data in healthy adults. In particular, T1 times of the lateral and inferior myocardial segments were higher. Conclusion Patients who underwent cardiac transplantation in childhood seem to have a reduced bioelasticity of the thoracic aorta. Increased myocardial T1 times suggesting alterations in myocardial structure. FUNDunding Acknowledgement Type of funding sources: None.

Aortic Dissection Type A

The purpose of this case presentation is to present a simplified surgical technique when in a patient with acute aortic dissection type A (AAD), aortic arch, and ascending aorta is completely replaced without circulatory arrest. A 67-year old male was presented in our institution with severe chest and back pain at 12 h after the onset of the symptoms. Imaging studies by 3D contrast-enhanced thoracic computed tomography (CT-scan) and transesophageal echocardiography (TEE) revealed ascending aortic dissection towards the aortic arch, which was extending in the proximal descending aorta. We practiced emergency median sternotomy and established cardiopulmonary bypass (CBP) between the right atrium and the right femoral artery with successive cross-clamping of the ascending and descending aorta below the origin of the left subclavian artery (LSA). In normothermic condition without circulatory arrest and with antegrade cerebral perfusion, we replaced the ascending aorta and aortic arch with a four branched Dacron graft. Patient evolution was uneventful, and he was discharged, after fourteen days from the hospital. At a one-year follow-up, 3D CT-scan showed no residual dissection with a well-circulated lumen of the supra-aortic arteries. Using the described surgical approach, CPB was not interrupted, the brain was protected, and hypothermia was no used. This approach made these surgical procedures shorter, and known complications of hypothermia and circulatory arrest are avoided.Acute aortic dissection aortic type A, total arch replacement, normothermia

Abstract Background The treatment for extensive aortic arch aneurysms involving the aortic arch and descending aorta is challenging for most cardiovascular surgeons. The surgical treatment is associated with a very high mortality rate. The optimal treatment has not been defined. Case presentation A 49-year-old male was hospitalized due to chest and upper back pain. Computed tomography angiography (CTA) demonstrated there was an extensive aortic arch aneurysm extending to the left common carotid artery and descending aorta. A novel single- stage hybrid surgery was performed on the patient through two steps: treatment of the aortic arch through median sternotomy and thoracic endovascular artery repair. The patient recovered uneventfully. Conclusions Our single-stage hybrid repair approach is safe, simple and effective. It provides an alternative treatment for extensive aortic arch aneurysms.

Cardiovascular Anomaly

“Persistence of the fifth aortic arch” is a rare congenital cardiovascular anomaly that consists of an abnormal vessel arising from the distal ascending aorta connecting with the systemic or pulmonary circulation. We report a case of a type A interruption of the aortic arch and a coarctation of the fifth aortic arch, which connected the ascending with the descending aorta. No cardiac surgery was required because a covered stent was successfully implanted in the fifth aortic arch when the patient was 4 years old. A chromosome 9 q arm duplication of uncertain significance was also found, an anomaly never described before in this clinical context.
