What is the cause of hypotension? A rare complication of percutaneous coronary intervention of a chronic total occlusion: a case report.

Severe hypotension during percutaneous treatment of chronically occluded coronary arteries may be related to various causes. Differential diagnosis is thus important in this setting and should include IMH, a rare but potentially fatal complication as it may cause compression of cardiac chambers and lead to pseudotamponade. A high index of suspicion is required to diagnose IMH but there are no clear guidelines for management of such cases.
