Axillary artery access for stenting of aortic coarctation in a 1.2 kg premature newborn with malignant systemic hypertension: a case report.

ABSTRACT:

Background?

Axillary artery access is rarely used for demanding percutaneous transcatheter interventions. However, there are many clear advantages.

Case summary?

We describe this attractive approach in a 3-week-old premature neonate (bodyweight of 1.2?kg) with severe aortic coarctation. Percutaneous transcatheter intervention was performed with analgo-sedation and local anaesthesia; and a coronary stent was placed with a low fluoroscopy time of 2 min. Malignant systemic hypertension (160/54?mmHg) was effectively treated without any residual blood pressure gradient, with the aim for definitive surgery with stent resection and end-to-end anastomosis at the age of 6-12?months.

Discussion?

Axillary artery access is an attractive, alternative approach to treat newborns and premature infants with low body weight with complex heart diseases.

Project description:ObjectivesThis study aimed to explore aortic morphology and the associations between morphological features and cardiovascular function in a population of patients with bicuspid aortic valve, while further assessing differences between patients with repaired coarctation, patients with unrepaired coarctation and patients without coarctation.MethodsThis is a single-centre retrospective study that included patients with available cardiovascular magnetic resonance imaging data and native bicuspid aortic valve diagnosis (n = 525). A statistical shape analysis was performed on patients with a 3-dimensional magnetic imaging resonance (MRI) dataset (n = 108), deriving 3-dimensional aortic reconstructions and computing a mean aortic shape (template) for the whole population as well as for the 3 subgroups of interest (no coarctation, repaired coarctation and unrepaired coarctation). Shape deformations (modes) were computed and correlated with demographic variables, 2-dimensional MRI measurements and volumetric and functional data.ResultsOverall, the results showed that patients with coarctation tended towards a more Gothic arch architecture, with decreased ascending and increased descending aorta diameters, with the unrepaired-aortic coarctation subgroup exhibiting more ascending aorta dilation. Careful assessment of patients with repaired coarctation only revealed that a more Gothic arch, increased descending aorta dimensions and ascending aorta dilation were associated with reduced ejection fraction (P ≤ 0.04), increased end-diastolic volume (P ≤ 0.04) and increased ventricular mass (P ≤ 0.02), with arch morphology distinguishing patients with and without recoarctation (P = 0.05).ConclusionsA statistical shape modelling framework was applied to a bicuspid aortic valve population revealing nuanced differences in arch morphology and demonstrating that morphological features, not immediately described by conventional measurements, can indicate those shape phenotypes associated with compromised function and thus possibly warranting closer follow-up.
