Out-of-hospital cardiopulmonary arrest due to penetrating cardiac injury treated by percutaneous cardiopulmonary support in the emergency room: report of a case

Blind subxiphoid pericardiotomy to relieve critical acute hemopericardium: a final report

PURPOSE

Percutaneous catheter drainage (PCD) has been considered a standard method of relieving acute cardiac tamponade. Although conventional subxiphoid pericardiotomy is useful even for clotted hemopericardium, it has been believed to be unsuitable for emergency treatment because it is a time-consuming procedure. We report our modified pericardiotomy technique that can be used for emergency management.

METHODS

We designed a prospective observational study to evaluate blind subxiphoid pericardiotomy (BSP) for critical cardiac tamponade due to hemopericardium. Emergency patients (n = 148) with acute hemopericardium secondary to trauma (n = 12), acute aortic disease (n = 122), or cardiac rupture following acute myocardial infarction (n = 14) were the subjects. Early results were compared between the BSP group (n = 53) and the PCD group (n = 95).

RESULTS

BSP was effective at relieving cardiac tamponade in all 53 cases, but PCD was ineffective in 12 cases (12.6 %, p = 0.008). Procedure-related complication rates of BSP and PCD were 0 and 16.8 %, respectively (p = 0.002). Survival rates for the BSP and PCD groups were 18.9 and 6.3 %, respectively (p = 0.018). Since 2005, when we discarded the restriction that only board-certified surgeons should perform BSP, acute care physicians (including trainees) have performed BSP for 22 patients without procedure-related complications.

CONCLUSIONS

BSP was safe and effective for cardiac tamponade due to acute hemopericardium. Critical complications during PCD for hemopericardium could not be avoided in some cases because of clots in the pericardium.

How to mend a broken heart: a major stab wound of the left ventricle

A 28-year-old male admitted with a stab wound under his left nipple, underwent emergency surgery because of confusion, a decreasing blood pressure and increasing tachycardia. A median sternotomy incision was made and after establishing cardiopulmonary bypass, a 7 cm wound in the left ventricle and a smaller wound in the left atrium were repaired. An injured segment of lung was resected and the left anterior descending and circumflex arteries were grafted after weaning from cardiopulmonary bypass was initially unsuccessful. Although the patient suffered a stroke, probably due to prehospital hypoperfusion, he eventually recovered without major sequelae. In addition to the case report we present a literature review of the last 15 years pertaining the management of penetrating cardiac injury.
