Coronary sinus (CS) dissection has been described as a complication of pacing electrode implantation only.1
We report here the diagnosis and surgical therapy of spontaneous rupture of a dissected CS in a patient with acute coronary syndrome (ACS) and circumflex artery (CX) to the CS fistula.
Clinical Summary
ACS was suspected in a 63-year-old man with acute chest pain after physical exertion but with no electrocardiographic signs of acute myocardial infarction. Coronary angiography showed a giant left main coronary artery aneurysm. A very ectatic and calcified CX originated from the aneurysm and drained into a huge CS. There were no coronary stenoses. Transesophageal echocardiographic analysis revealed a possibly hemorrhagic pericardial effusion. Septated echodense structures were found within the CS lumen that were indicative of chronic dissection (
Figure 1, A). Turbulent flow inside the CS was indicative of arterial pressure (Figure 1, B). Cardiac electrocardiographically
