Heart HQ: Coronary Artery Anomalies

Heart HQ – Episode 8: Coronary Artery Anomalies and HRT

In this week’s podcast, Peter and Stuart chat about coronary artery anomalies.

There are many different types of coronary artery anomalies such as an inter-arterial course and a coronary artery fistula. Peter and Stuart discuss a couple of recent patients who had a fistula, and were diagnosed thanks to a CT Coronary Angiography (CTCA) scan.

And, prompted by a recent patient enquiry about the risk of cardiovascular disease when using hormone replacement therapy (HRT), they also discuss the 5 things to consider when it comes to HRT and CVD.

Show notes: Episode 8
Hormone Replacement Therapy (HRT)

For more on HRT and CVD risk, please refer to Figure 3 in the Treatment of Symptoms of the Menopause: An Endocrine Society Clinical Practice Guideline.

Conceptual diagram of possible paths
Figure 3. Conceptual diagram that shows most of the possible paths (1 through 5) by which the RCA, left anterior descending artery (LAD), and circumflex artery (Cx) can potentially connect with the opposite coronary cusps.
1, Retrocardiac;
2, retroaortic;
3, preaortic, or between the aorta and pulmonary artery;
4, intraseptal (supracristal);
5, prepulmonary (precardiac).
The aortic and pulmonary cusps are labeled according to their position in space: AL indicates antero-left; AR, antero-right; P, posterior; M, mitral valve; and T, tricuspid valve. Angelini 1999
