Article Synopsis
- A case of an aortopulmonary fistula related to a post-operative aortic pseudoaneurysm is discussed, which is a rare complication following aortic surgery.
- The patient, a 60-year-old man with severe heart failure unresponsive to diuretics, was diagnosed after advanced imaging techniques revealed shunt blood flow from the aortic aneurysm to the pulmonary artery.
- The study emphasizes the effectiveness of transesophageal echocardiography for accurately diagnosing this condition, as it provides better details than routine imaging methods like CT angiography.
Since Agatston et al. first reported quantification of the coronary artery calcification score (CACS) in 1990, discussion of its clinical significance and use in diagnostic management has continued. Recent papers have reported the relationship between CACS and myocardial perfusion single photon emission computed tomography (SPECT: MPS) and its combined diagnostic value.

- * Results showed that RV pacing with an optimal AV delay of 160 ms led to a higher stroke volume compared to intrinsic AV conduction, prompting the use of DDD mode pacing.
- * However, seven of the patients developed heart failure during the follow-up, particularly when their E/E' ratio was above 15, indicating the need to avoid RV pacing in patients with elevated E/E' ratios.
