Percutaneous coronary intervention (PCI) is an effective method for coronary revascularization, however, alongside its benefits, it can be accompanied by complications. Catheter induced coronary artery dissection (CICAD) is rare and the consequences can be devastating if left untreated. The incidence has been reported to be as low as 0.1%. Also, propagation of the dissection to the aortic root remains uncommon. The mechanism of dissection is related to mechanical injury to the arterial wall during manipulation with the catheter or wire. It may also occur due to injection of contrast, stenting or balloon dilation. Timely recognition is important in these cases to facilitate optimal patient outcomes which is usually accomplished with stenting. Herein, we report a rare case of a 68-year-old female with multivessel coronary artery disease who presented for routine left heart catheterization and developed catheter induced right coronary artery (RCA) dissection with propagation towards the aortic root which was treated with stenting and watchful waiting.

McKittrick–Wheelock syndrome commonly presents with a triad of chronic secretory diarrhea, electrolyte disturbances, and renal failure. Secretory diarrhea is due to active ion secretion secondary to secretagogue secretion (cyclic adenosine monophosphate and prostaglandin E2). The mainstay of treatment for these lesions is surgical since it will arrest the loss of electrolytes that may lead to serious clinical consequences. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as indomethacin may be used to decrease electrolyte secretion in patients that desire a nonsurgical approach. Our patient is unique in that this is the first case of a tubular adenoma with high-grade dysplasia leading to MWS and progressing to circulatory collapse with severe electrolyte disturbances. Aggressive replacement of fluids and electrolytes is essential to the survival of these patients. [ABSTRACT FROM AUTHOR]
