The arterial phase acquisition is limited by motion artifact of the ascending aorta. Also seen is the tip of the IABP in the mid descending aorta. Note that the balloon is not seen as a continuous inflated structure because of the ‘non-gated’ images acquisition (not synchronized to heart beat)

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.

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.

Abstract Objectives: To evaluate the impact of fetal haemodynamics on surgical and neurodevelopmental outcomes in severe Ebstein anomaly and tricuspid valve dysplasia. Methods: Thirty-four fetuses with Ebstein anomaly/tricuspid valve dysplasia were referred from 2013 to 2019 for fetal echocardiography and clinical management. Nineteen fetuses with Ebstein anomaly/tricuspid valve dysplasia and 30 controls underwent cardiovascular magnetic resonance to quantify the fetal blood flow and to calculate cerebral oxygen delivery (cDO2) and consumption (cVO2). The 3D steady-state free precession acquisition was used to measure fetal brain volume. Surgical outcome, brain MRI, and neurodevelopmental follow-up were reviewed. Results: Twenty-six fetuses were live born (76%) and survival (65%) at a mean follow-up of 4 years. Nine fetuses had a brain MRI before discharge, and all had clinically silent injuries and volume loss. At 18 months, five single-ventricle patients had a neurodevelopmental delay in cognition and language (mean percentile: 11th), with gross-motor skills more affected than fine-motor skills (mean percentiles: 4th and 34th). Fetuses with Ebstein anomaly/tricuspid valve dysplasia had smaller brains, lower combined ventricular output, ascending aorta, superior caval vien and umbilical vein flows, lower oxygen saturation in ascending aorta and superior caval vien, lower cDO2 and cVO2 (p < 0.05). Superior caval vien/combined ventricular output and descending aorta/combined ventricular output ratios were lower in fetuses with circular shunt (p < 0.05). Fetuses requiring the Starnes procedure tended to have smaller brains, lower combined ventricular output, superior caval vien, descending aorta, and umbilical vein flows. Conclusions: All patients with Ebstein anomaly/tricuspid valve dysplasia are at high risk of neurodevelopmental delay and warrant follow-up. Fetal cardiovascular magnetic resonance revealed impaired brain growth with diminished cerebral blood flow and cDO2, the extenting dependent on the severity of the haemodynamic compromise.

Background: Dicrotic Notch (DN) is known to dampen with age, with increasing arterial stiffness probably due to arterial calcification. Since arterial calcification has recently been shown to predominantly involve descending thoracic aorta, we hypothesized that calcification in different segments of thoracic aorta will have a different impact on DN. Methods: A sample of 44 patients with invasive thoracic aortic pressure tracings during cardiac catheterization was selected for this study. Non-contrast CT scans were evaluated for presence of calcification in aortic segments (ascending aorta (AA), aortic arch (arch) and descending aorta (DA)) and then quantified. DN was categorized based on aortic pressure tracings into 4 grades. Grade 1 represented normal DN; grades 2, 3 and 4 represented progressively diminishing DN, where grade 4 represented absent DN. Compliance was calculated as a change in stroke volume over aortic pulse pressure with both measurements obtained from echocardiography reports done within one year of catheterization. Results: The mean age of the sample population was 64.6 ± 10.5 years. Out of the 44 patients, 14 (32%) had a calcified AA, 25 (56%) had a calcified DA and n=28 (63%) had a calcified arch. Furthermore, 14 (32%) patients had only one segment calcified, whereas 10 (23%) had two and 11 (25%) had all three segments calcified. Abnormal DN was present in 16 (36%) patients. The odds of having an abnormal DN in the presence of calcified AA were more than 3 times (OR: 3.67; p=0.05). Compliance was higher in those with a normal DN versus those with an abnormal DN (1.64 ml/mmHg vs. 1.21 ml/mmHg) (p = 0.09). There was no significant association between calcification in the DA or arch of aorta. Conclusion: There was no association between dicrotic notch and presence of calcification in the arch of the aorta and descending aorta.
