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.

Objective. To prospectively evaluate our hypothesis that three-dimensional time-resolved contrast-enhanced magnetic resonance angiography (TR-MRA) is able to detect hemodynamic alterations in patients with chronic expanding aortic dissection compared to stable aortic dissections. Materials and Methods. 20 patients with chronic or residual aortic dissection in the descending aorta and patent false lumen underwent TR-MRA of the aorta at 1.5 T and repeated follow-up imaging (mean follow-up 5.4 years). 7 patients showed chronic aortic expansion and 13 patients had stable aortic diameters. Regions of interest were placed in the nondissected ascending aorta and the false lumen of the descending aorta at the level of the diaphragm (FL-diaphragm level) resulting in respective time-intensity curves. Results. For the FL-diaphragm level, time-to-peak intensity and full width at half maximum were significantly shorter in the expansion group compared to the stable group (p=0.027 and p=0.003), and upward and downward slopes of time-intensity curves were significantly steeper (p=0.015 and p=0.005). The delay of peak intensity in the FL-diaphragm level compared to the nondissected ascending aorta was significantly shorter in the expansion group compared to the stable group (p=0.01). Conclusions. 3D TR-MRA detects significant alterations of hemodynamics within the patent false lumen of chronic expanding aortic dissections compared to stable aortic dissections.

Background: Presentations and outcomes of acute aortic dissection (AD) with an entry tear in the ascending aorta may differ from retrograde dissection with an entry tear in the descending aorta. However, guidelines recommend urgent surgical repair for both entities. Methods and Results: All patients with AD enrolled in the International Registry of Acute Aortic Dissection (IRAD) between 1996 and 2014 were analyzed. We identified 99 patients (67 men; 63.2±14.0 years) with an entry tear in the descending aorta and retrograde extension into the arch or ascending aorta. Overall, independent predictors of retrograde type A AD were increasing age(OR 1.0; 95% CI, 1.0 to 1.0; P=0.004), history of cocaine abuse (OR 4.9; 95% CI, 1.7 to 13.6; P=0.003), back pain at presentation (OR 2.1; 95% CI, 1.3 to 3.3; P=0.002), and non-white race (OR 0.4; 95% CI, 0.2 to 0.6; P<0.001). During initial hospitalization, 44 of these patients were managed medically (MED), 33 with open surgery(SURG) and 22with endovascular therapy (ENDO). Patients in the SURG group presented with larger ascending aortic diameters than MED and ENDO patients (P=0.04). The majority of the MED (72.7%) and ENDO (86.4%) patients had AD extension confined to zone 1 (proximal arch, P<0.001), whereas most of the SURG patients (71.8%) presented with AD extension into zone 0 (proximal to the innominate artery, P<0.001). Early (30-day or in-hospital) mortality rates of the MED, SURG and ENDO groups were 9.1%, 18.2%, and 13.6%, respectively (P=0.51), with 5-year survival of 86.7%, 80.0%, and 90.9%, respectively (mean follow-up, 3.3 years, log rank P=0.67). A trend of favorable early mortality was observed in patients with retrograde extension till zone 1 (8.6%) versus into zone 0 (18.6%, P=0.14).Early mortality of patients with retrograde type A AD (12.9%) was lower than those with type A AD (20.0%, P=0.001), while 5-year survival was similar (86.8% and 89.5%, respectively, mean follow-up, 3.0 years, log rank P=0.96). Conclusion: There is a subset of patients with acute retrograde type A AD who can be managed non-operatively with acceptable short and long-term results. This implies that a selective approach may be reasonable, particularly among those with proximal extension limited to the arch distal to the innominate artery.

Purpose: To evaluate the safety and efficacy of thoracic endovascular aortic repair (TEVAR) for retrograde type A intramural hematoma (IMH) with intimal disruption in the descending aorta and report our endovascular therapeutic experience. Materials and Methods: From January 2014 to October 2020, a total of 24 consecutive patients with retrograde type A IMH with intimal disruption (intimal tear or ulcer-like projection) in the descending aorta underwent TEVAR. The demographics, clinical characteristics, treatment details, imaging information, and follow-up results were reviewed. Results: Among all patients with retrograde type A IMH, 13 (54.2%) patients presented with ulcer-like projection and 11 (45.8%) with intimal tear (aortic dissection) in the descending aorta. Successful TEVAR was achieved in all patients. There was no 30-day mortality. During a mean follow-up of 37.5 months, 1 patient (4.2%) developed permanent paralysis, 1 patient (4.2%) underwent reintervention due to the expansion of the aorta distal to the stent resulting from the enlargement of distal intimal tear at the 2 month follow up, and no other adverse events were observed. The latest computed tomographic angiography images showed that the maximum diameter of the ascending aorta and descending aorta significantly decreased after TEVAR (both p<0.001), and the IMH/false lumen in the ascending aorta and the descending thoracic aorta were completely absorbed. Conclusion: Thoracic endovascular aortic repair for selected patients with retrograde type A intramural hematoma that presented with intimal disruption in the descending aorta is feasible and efficient, but close surveillance is needed to manage aortic-related adverse events.

A 71-year-old woman was admitted with sudden onset of severe chest pain. Computed tomography demonstrated acute type A intramural hematoma with an entry tear in the first part of the descending aorta. The patient refused an operation. Endovascular repair was performed to prevent conversion to a typical dissection of the ascending aorta. At the 1-year follow-up, computed tomography showed total resolution of the intramural hematoma.

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.
