“…Only few cases, including ours, exist. Reviewing the current literature, transposition of the great arteries seems to be most frequently associated with this kind of anomaly 6,7,15–17 . Anomalies of the coronary arteries, in general, are found to be associated with mitral valve prolapse followed by bicuspid aortic valves, tetralogy of Fallot, and transposition of the great arteries 6,7 .…”

“…According to our literature review, transposition of the great arteries seems to be the CHD most frequently associated with this anomaly. 6,7,[15][16][17] Here, we report about a patient with tetralogy of Fallot who underwent TEE before surgical valve replacement and a coronary anomaly could be identified. The overall reported incidence of malformations of the coronary arteries in tetralogy of Fallot differs between a minimum of 2-9% 9,10 and a maximum of 19-36% of cases.…”

Anomalies of the coronary arteries are commonly associated with congenital heart disease (CHD). Anomalies include variations in number, shape, and location of the origin, as well as the course of the coronary artery. An intramural course of one of the coronary arteries is a rather rare condition. Most cases of anomalies are of no clinical relevance and are found incidentally during evaluation for other cardiac conditions. However, they become of importance when cardiac surgery/intervention, especially valve replacement, needs to be performed. We conducted a literature review for coronary anomalies with an intramural course in patients with CHD and include three cases from our own clinic. Note that transposition of the great arteries seems to be the condition most frequently associated with an intramural course of one of the coronary arteries. In case of a suspected anomaly, transesophageal echocardiography presents a valuable tool to visualize the origin and course of the coronary artery, as well as the relationship to important anatomical structures like the aortic or pulmonary valve. Alternatively, cardiac magnetic resonance imaging can be used. Although rare, both cardiologists and surgeons need to be aware of intramural courses of coronary arteries to prevent accidental trauma to them and thereby, reducing the risk for the patient.

“…[3][4][5]9,10 Improvements have been noted but overall survival has been less favorable than that for neonatal biventricular repair surgery. 6,11 The change in the slope of the mortality curve for HLHS occurs in concert with a change from in-parallel circulation (stage 1) to an in-series circulation (stage 2). We propose as an overall hypothesis that the physiologic demands of single ventricle in-parallel circulation are a major contributor to the high early attrition.…”

Primary In-Series Palliation of Hypoplastic Left Heart Syndrome With Mechanical Lung Assist in Neonatal Pigs

et al. 2009

Less than optimal outcomes for hypoplastic left heart syndrome may be related to unstable in-parallel circulation. Mechanical lung assist by (1) superior vena cava to right atrium pump with oxygenation (oxygenator assist), or (2) superior vena cava to pulmonary artery pump (pump assist) may permit successful neonatal in-series palliation. Nineteen 15-day-old piglets underwent single ventricle and bidirectional cavopulmonary shunt (BCPC) creation without mechanical lung assist (n = 8), with pump assist (n = 5), or with oxygenator assist (n = 6). Baseline hemodynamic measurements were not different between groups. Median survival for the cavopulmonary shunt alone, pump assist, and oxygenator assist groups was 28, 180, and 180 minutes, respectively (p = 0.0006). No differences in arterial oxygen concentration or bicarbonate levels were detected. Arterial carbon dioxide (p < or = 0.007) was higher in the cavopulmonary shunt alone versus lung assist groups. Cavopulmonary shunt alone animals had decreased mean arterial pressure (p < 0.02) and cerebral perfusion pressure (p = 0.029) and elevated left atrial pressure compared with lung assist groups (p < 0.05). This data demonstrates creation of a novel translational neonatal BCPC model in which mechanical lung assist augments survival. Early BCPC death was related to poor ventricular function and an inability to ventilate, issues that were improved with both types of lung assist.

“…While stenosis or occlusion is the usual pattern of involvement, aneurysms are rare 1 . TTE plays an important role in the evaluation of coronaries in congenital heart disease 2 and Kawasaki disease 3 . However, in adult patients with poor transthoracic window, TEE has been used as an excellent noninvasive technique for assessing LMCA anatomy 4 .…”

Left Main Coronary Artery Aneurysm in Takayasu Arteritis

An 18-year-old lady, a patient of Takayasu arteritis was referred to our hospital with a history of recurrent giddiness and resistant hypertension for 6 months. On examination, she had weak left carotid and left arm pulses and bilateral renal bruit. Investigations revealed bilateral renal artery stenosis with preserved renal size and architecture. Transthoracic echocardiogram (TTE) showed concentric left ventricular hypertrophy with ejection fraction of 50% and type I diastolic dysfunction. The aortic
