Background: Cardiac tamponade with acute aortic dissection type A can cause fatal outcomes. We previously reported excellent outcomes using percutaneous pericardial drainage with controlled volumes of aspirated pericardial effusion (controlled pericardial drainage [CPD]) to stabilize patients with critical cardiac tamponade. This study evaluates the early and late outcomes using this approach.
Methods: Between September 2003 and July 2018, 308 patients with acute aortic dissection type A were treated surgically, including 76 patients who presented with cardiac tamponade on hospital arrival. Forty-nine patients who did not respond to intravenous volume resuscitation underwent CPD in the emergency room, including 14 patients (28.6%) who presented with cardiopulmonary arrest. After CPD 39 patients (79.6%) were transferred to the operating room to undergo immediate aortic repair. The remaining 10 patients (20.4%) received medical treatment on arrival, followed by aortic repair within several days.
Results: In 49 patients the mean systolic blood pressure before CPD was 64.4 ± 10.3 mm Hg. Blood pressure rose significantly in all patients after CPD. The total volume of aspirated pericardial effusion was 46.8 ± 56.2 mL, and 30 of 49 patients (61%) required only 30 mL or less of aspiration to improve their blood pressure. All patients underwent successful aortic repair. Early hospital mortality was 16%. However there was no mortality related to CPD. The mean follow-up period was 52.9 ± 54.3 months. The cumulative survival rate was 63.4% after 5 years.
Conclusions: CPD for critical cardiac tamponade with acute type A aortic dissection produced satisfactory early and late outcomes.
