hemodynamic support
Pronunciation: HEE-mo-dy-nam-ik
Mechanical circulatory assistance used to maintain blood pressure and cardiac output during high-risk percutaneous coronary interventions.
Full Definition
Hemodynamic support encompasses various mechanical devices used to augment cardiac output and maintain systemic perfusion during complex percutaneous coronary interventions or in cardiogenic shock. Options include intra-aortic balloon pumps, percutaneous ventricular assist devices (Impella), extracorporeal membrane oxygenation (ECMO), and percutaneous cardiopulmonary bypass. Device selection depends on the degree of support required, vascular access considerations, and duration of anticipated use. Hemodynamic support enables intervention in patients who would otherwise be inoperable due to poor left ventricular function or cardiogenic shock, but requires specialized expertise and careful patient selection.
Usage
Usage note: Distinguish from pharmacologic support (inotropes, vasopressors) which works through different mechanisms.
In Context
- "Prophylactic hemodynamic support was initiated prior to intervention in the last remaining vessel." — High-risk procedural planning
- "The patient required escalation of hemodynamic support due to procedural complications." — Complication management
