Anomalous Aortic Origin Of Coronary Artery Research Articles

Family perception of unmet support needs following a diagnosis of congenital coronary anomaly in children: Results of a survey.

Long-term outcome data on patients with anomalous aortic origin of coronary arteries (AAOCA) is sparse and they are often managed in a nonuniform manner. There is subjective perception of anxiety and unmet needs in these patients and families. An online survey of 13 questions was sent to 74 families of patients with AAOCA between May and October 2015. Descriptive statistics were performed. A total of 31 (47%) families responded. Of these, 27 expressed the need to interact with other patients/families with AAOCA. The majority were interested in either face-to-face meetings (77%) or online support groups (71%). Regarding content of the meeting, 74% were interested in brief talks by medical personnel/families, 58% suggested informal interactions with families, 55% proposed a structured discussion with a moderator and 39% mentioned fun activities/games. Regarding participants in these meetings, 90% would like to include healthcare providers, 61% suggested including family friends, 58% wished to include psychologists and 16% mentioned including social workers. The families currently use various social media including Facebook (87%), YouTube (39%), Google+ (36%), and LinkedIn (32%). For future online resources, 77% of families would like a Facebook site, an informative website (58%), a blog (52%), or an open forum (29%). The majority of the families (77%) were interested in attending a dedicated AAOCA meeting. There appears to be an unmet need for family support in those affected by AAOCA, a substantial life changing diagnosis for patients and families. Further research is needed to assess quality of life in this population.

FEASIBILITY OF RAPIDLY CREATING HIGH RESOLUTION VIRTUAL THREE-DIMENSIONAL MODELS OF ANOMALOUS AORTIC ORIGIN OF CORONARY ARTERIES

Background: Morphological criteria that result in inducible ischemia with anomalous aortic origin of coronary artery (AAOCA) have been postulated but not confirmed. Computational fluid dynamics (CFD), finite element analysis (FEA) on virtual AAOCA three-dimensional models (3DM) could elucidate the

Coronary arteries anomalous aortic origin on a computed tomography angiography population: prevalence, characteristics and clinical impact.

Anomalous aortic origin of coronary arteries (AAOCA) is one of the most frequent causes of cardiovascular sudden death among the young population. We aimed to determine the prevalence and anatomic characteristics of AAOCA in a population referred to computed tomography angiography (CTA) and to describe the clinical prognosis of these findings at middle term follow-up. From a total of 3539 CTA, 53 were found to have AAOCA. This population was compared to an age and gender matched control group (n=106) from the same CTA list. A telephone follow-up to determine cardiac events was conducted, with a mean follow-up of 45.9±28.2months. Prevalence of AAOCA was 1.5%. The most common AAOCA was an origin of the right coronary artery (RCA) from the left coronary sinus, followed by an origin of the left circumflex artery (LCX) arising from the right coronary sinus. All patients with an anomalous origin of the RCA had an interarterial course. Four additional patients were found to have an interarterial course: 1 with an anomalous origin of LCX and 3 with an anomalous origin of the left main coronary artery (LMCA). At follow-up there were 33 (21.2%) cardiac events, 9 (17.6%) on the AAOCA group and 24 (22.9%) on the control group (p=0.46). Cardiac events and cardiovascular deaths were not related to any particular AAOCA or to interarterial courses. Among an adult population referred to CTA, AAOCA were not related with worse middle term prognosis when compared to an age- and gender- matched population.

Anomalous Aortic Origin of Coronary Arteries: A Single-Center Experience

The aim of this article is to determine the clinical course and outcomes in subjects with anomalous aortic origin of coronary arteries (AAOCA), particularly after surgical repair. A single-center, retrospective review of patients with AAOCA with right or left interarterial or IM (IA or IM) or intraconal course from 1996-2014. Among 155 patients, median age at diagnosis was 8.5 (range: 0.1-50) years, and 65% were male. The AAOCA course was IA or IM in 151 (97%) and intraconal in 4 (3%). Anomalous right coronary artery (CA) was present in 127 (82%), of whom 52 (42%) had repair. Anomalous left CA (ALCA) was present in 28 (18%), of whom 20 (71%) had repair. In the surgical group, 70 (97%) had IA or IM CAs; CA unroofing was performed in 62 (86%). In univariable analysis, surgical management was associated with ALCA (28% vs 10%, P = 0.003), age > 10 years (median 11 vs 6 years, P < 0.001), symptoms (63% vs 13%, P < 0.001), and exercise restriction at the time of diagnosis (47% vs 13%, P < 0.001). In multivariable modeling, surgery was associated with chest pain or syncope (P < 0.001) and older age (P = 0.03). Major perioperative complications occurred in 4 cases (6%) and 1 patient had late aortic valve repair. In the surgical group, no patients died; in the observed group, 2 patients with anomalous right CA (2.3%) died of severe noncardiac comorbidities. In our center, surgery for AAOCA was not associated with mortality, and surgery was recommended in patients with ALCA with IA or IM course. Rare but serious surgical complications highlight the importance of long-term follow up of patients with AAOCA to develop evidence-based management guidelines.
