The accordion phenomenon is a rare pseudo-complication observed during percutaneous coronary intervention (PCI), which can mimic coronary dissection, spasm, or thrombus formation. Here we present a patient with inferior ST-segment elevation myocardial infarction (STEMI), who developed multiple pseudo lesions in the tortuous right coronary artery (RCA) during PCI. An emergency coronary angiography was performed, but unfortunately, the lesion developed into an accordion-like shape in the middle segment of the right coronary artery (RCA), which looked like a coronary dissection.

Case: The accordion phenomenon is defined as the difference in the disc space observed on x-ray or computed tomography images taken in both standing and supine positions, which results in a discrepancy of local spinal alignment. Oblique lateral interbody fusion (OLIF) is a less invasive method of potentially correcting both coronal and sagittal spinal alignment. We present the case of a 66-year-old woman with rheumatoid arthritis treated with OLIF for degenerative disc disease presenting with hyperlordosis and negative sagittal vertical axis (SVA) because of the accordion phenomenon.

In higher plants, photosystems II and I are found in grana stacks and unstacked stroma lamellae, respectively. To connect them, electron carriers negotiate tortuous multi-media paths and are subject to macromolecular blocking. Why does evolution select an apparently unnecessary, inefficient bipartition? Here we systematically explain this perplexing phenomenon.
