Insights
This case report details a rare instance of coronary artery perforation into the gastrointestinal tract during a procedure for inferior myocardial infarction. A covered stent successfully managed the perforation, achieving re-hemostasis.
Area of Science:
- Cardiology
- Gastroenterology
- Interventional Radiology
Background:
- An 82-year-old male with a history of stomach cancer surgery presented with severe gastrointestinal bleeding and hypotension.
- Initial evaluation revealed inferior myocardial infarction and active gastric ulceration.
Observation:
- Upper endoscopy identified a bleeding gastric ulcer, which was treated with hemoclips.
- Coronary angiography for an occluded right coronary artery (RCA) segment 4 atrioventricular (AV) led to coronary perforation during angioplasty.
- Contrast material extravasation into the gastrointestinal cavity was observed during angiography.
Findings:
- A covered stent was deployed in the RCA (segment 3 to 4 PD) to occlude the perforation site.
- Successful re-hemostasis was achieved after stent placement.
- This represents the first reported case of coronary artery perforation into the gastrointestinal tract.
Implications:
- Highlights a rare but serious complication of percutaneous coronary intervention.
- Demonstrates the successful management of coronary-gastrointestinal fistula using a covered stent.
- Emphasizes the importance of multidisciplinary collaboration in managing complex cardiovascular and gastrointestinal emergencies.
Abstract:
An 82-year-old man who had previously undergone a proximal gastrectomy with jejunal interposition surgery for stomach cancer was transferred to our hospital for massive hematemesis and hypotension. His electrocardiogram showed ST-segment elevation in lead ΙΙ, ΙΙΙ, aVF, which confirmed inferior myocardial infarction. Due to active hematemesis, upper endoscopy was performed initially. A visible vessel of gastric ulceration was discovered, and hemostasis was achieved using hemoclips. Subsequently, coronary angiography was performed since the right coronary artery (RCA) segment 4 atrioventricular (AV) was occluded. After thrombectomy and intravascular ultrasound (IVUS), 2.0 mm balloon angioplasty was done, and coronary perforation occurred. During coronary angiography, extravasation of the contrast material into the gastrointestinal cavity was noted. A covered stent was placed across segment 3 to segment 4 descending posteriorly (PD) to stop the blood supply to the perforation site of segment 4 AV. After stenting, adequate re-hemostasis was achieved. The patient was discharged after 28 days. This is the first report of a coronary artery perforation into the gastrointestinal cavity.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
