Abstract:
The authors report a case of a 69-year-old man with a 5-year history of medically treated type B aortic dissection, who presented a new retrograde type A aortic dissection (RTAD) of the aortic arch and the ascending aorta. Clinical presentation was suggestive of pulmonary embolism. Computed tomographic angiography revealed a contained rupture of the dissected aortic arch, confined to the connective tissue plane between the arch and the pulmonary arteries. Extrinsic compression of both pulmonary arteries caused right heart failure. The patient was successfully operated with replacement of the dissected aortic arch, decompressing the pulmonary arteries. The combination of a secondary new RTAD after a chronic type B aortic dissection and a compression of the pulmonary arteries by a contained rupture of the dissected aortic arch have not been reported previously in literature.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
