Insights
Cardiac tamponade (CT) following cardiac interventions can be life-threatening. High-risk patients with rapid drainage (>300 mL/hr) may require immediate surgery, not just pericardiocentesis.
Area of Science:
- Cardiology
- Cardiac Surgery
- Interventional Cardiology
Background:
- Cardiac tamponade (CT) is a rare but critical complication post-cardiac interventions.
- Management decisions, often based on experience, involve pericardiocentesis or open-chest surgery.
- Identifying high-risk patients for early surgical intervention is crucial.
Purpose of the Study:
- To identify predictors of high-risk cardiac tamponade (CT) after cardiac interventions.
- To advocate for timely surgical intervention in specific CT patient cohorts.
Main Methods:
- Retrospective analysis of 51 patients with iatrogenic CT (Oct 2013-Oct 2023).
- Patients categorized by need for open-chest surgery versus pericardiocentesis.
- Evaluation of clinical factors, treatments, and outcomes.
Main Results:
- 49/51 patients treated successfully with pericardiocentesis (avg. drainage 208.2 mL).
- 2 patients needing surgery had >500 mL drainage, with >300 mL in the first hour, indicating lacerations.
- Non-surgical group showed favorable outcomes.
Conclusions:
- Pericardiocentesis is effective for most iatrogenic CT without lacerations.
- Lacerated injuries with rapid drainage (>300 mL/hr) may not stabilize with pericardiocentesis alone.
- Immediate surgery is indicated for hemodynamically unstable patients with suspected lacerations.
Background:
Cardiac tamponade (CT) is a rare but life-threatening complication of cardiac interventions, requiring immediate pericardial cavity pressure relief. While pericardiocentesis often suffices, and some cases necessitate open-chest surgery. This decision is frequently based on individual physician's experience. This study aims to identify high-risk CT patients following cardiac intervention, advocating for early, decisive surgical intervention.
Methods:
A retrospective analysis was conducted on 51 patients who developed iatrogenic CT at our center between October 2013 and October 2023. Patients were classified based on the necessity for open-chest surgery. The study evaluated a variety of factors, including baseline characteristics, therapeutic approaches, and outcomes.
Results:
Of the 51 patients with iatrogenic CT, 49 patients were successfully treated without open-chest surgery, with an average immediate drainage volume of 208.2 173.8 mL. In contrast, the two patients requiring open-chest surgery had significantly higher drainage volumes, exceeding 500 mL, with over 300 mL drained in the first hour, indicating laceration injuries. Patients not requiring open-chest surgery demonstrated favorable outcomes.
Conclusions:
The majority of patients with iatrogenic CT and non-lacerated injuries experienced a favorable prognosis following pericardiocentesis. However, in cases of lacerated injuries with drainage volume was above 300 mL per hour, pericardiocentesis alone could not stabilize the hemodynamics due to persistent bleeding. Immediate surgery may be needed in these cases.
