All's Not Well(ens) that Ends Well: Case Study of Significant Thebesian Veins Mimicking Wellens Syndrome.
Keith FrankPublished in: Spartan medical research journal (2020)
Thebeisan veins are microfistulous connections between a coronary arterial branch directly to a ventricular or atrial chamber. Extensive thebesian veins that empty into the left ventricle can cause typical chest pain symptoms, troponin elevation, and ischemic EKG changes from coronary steal leading to acute coronary syndrome in extreme cases. Literature review exposed a consistent pattern of EKG findings among patients with extensive thebesian veins involving all three major coronary arteries. We present a case study as an example of this rare anatomic finding of extensive thebesian veins draining into the left ventricle causing acute coronary syndrome in a symptomatic patient with elevated troponin and ischemic changes on EKG. This same EKG pattern that is present in our patient was discovered to be consistent among available case studies reviewed that had included an EKG tracing in their report. A newly proposed association between the ischemic changes on EKG due to extensive thebeisan veins and those of a severe proximal left anterior descending coronary artery stenotic lesion was discovered. The newly discovered consistency in the EKG pattern with acute coronary syndrome caused by extensive thebesian veins is the same pattern as that seen in Wellens Syndrome.
