NCT ID: NCT05912634 Enrolling by invitation - Aortic Dissection Clinical Trials

Repair Versus Non-repair of the Aortic Arch in Type A Aortic Dissection (TAAD)

AoArch
Start date: January 30, 2022
Phase:
Study type: Observational

Acute Stanford type A aortic dissection (TAAD) is a life-threatening clinical status requiring surgery that is usually performed as a salvage procedure.We planned a multicenter study to evaluate the balance between the patient's condition and those therapeutic strategies that may limit the risk of late adverse events in patients who will be underwent surgery for appropriate management of TAAD

Measurement of Heart-carotid Pulse Wave Velocity (hcPWV) by Laser Doppler Vibrometry (LDV)

InSide-CC
Start date: February 1, 2023
Phase: N/A
Study type: Interventional

Aortic stiffness is an important imaging biomarker of vascular aging. The ascending aorta is the most elastic segment, and it is excluded by reference non-invasive method carotid to femoral pulse wave velocity (PWV). We propose to use laser-doppler vibrometry (LDV) to record superficial vibrations generated by cardiac activity and arterial pulses for measuring heart carotid PWV, a surrogate for ascending aorta. The trial aims to demonstrate the equivalence between heart-carotid PWV made by laser-doppler vibrometry (LDV) with the reference MRI measurement (4D-FLOW MRI). As secondary objectives, A) we aim to assess the reproducibility of LDV, compared with MRI, B) show that aortic stiffness measured by LDV fulfils international recommendations, C) to study the association between PWV and age or other cardiovascular risk factors, D) assess the acceptability of the measurement. For this, we include 100 consecutive patients, 50 women, 50 men, scheduled for clinically indicated thoracic aorta MRI.

NCT ID: NCT05655767 Not yet recruiting - Aortic Aneurysm Clinical Trials

LANDMARC Study: a Study With Focus on Aorta Ascendens

Start date: December 15, 2022
Phase:
Study type: Observational

Rationale: Aortic diameter is currently used as a gold standard in international guidelines for prediction of aorta pathology (aortic aneurysm and aortic dissection). However, aortic diameter has proven to be insufficiently accurate for making decisions about well-timed preventive interventions. The LANDMARC study will take place in line with the FIBAA-bank ('Correlatie tussen cardiovasculaire FIBroseringsgraad en Aorta elongatie, dilatatie en Atria dilatatie (FIBAA-bank): een biobank & databank onderzoek met focus op aorta en atria' (METC-number 2022-3164)), and aims to reveal the undiscovered relationship between WSS (wall shear stress) values and aortic strain. In combination with data from the FIBAA-bank, the LANDMARC study will provide more accurate information for future risk stratification models for cardiovascular pathology (with focus on aortic disease). Objectives: Primary objective: indication of the association between WSS (peak WSS and WSS gradient) (through 4D-flow MR and CT) and aortic strain. Secondary objective: indication of the association between (hemo)dynamic processes within the body (aortic elongation/aortic strain) and (patho-)physiological changes (degree of cardiovascular tissue fibrosis).

NCT ID: NCT02283970 Completed - Clinical trials for Aortic Regurgitation

Investigation of Patients With BAV Requiring Valve and/or Aortic Repair (GISSI Outliers VAR)

VAR
Start date: December 2012
Phase:
Study type: Observational

Prospective longitudinal study on four small groups of surgical patients affected by: BAV with isolated regurgitation, BAV associated with aorta dilatation, or both and BAV with isolated stenosis in over 60 year-old patients. The aim of the study is to select homogeneous small groups of surgical patients with the same subtype of BAV and same aortic behaviour and identify markers/predictors of favorable-unfavorable aortic wall evolution to evaluate if there is a BAV phenotype more likely to be considered at high risk for aortic degeneration.
