Protective effect of previous cardiac operation: survival of contained right ventricular rupture

Area of Science:

• Cardiology
• Trauma Surgery
• Medical Case Reports

Background:

• Blunt chest trauma can cause cardiac contusions, but cardiac rupture is a rare and often fatal complication.
• High mortality rates for cardiac rupture mean patients rarely survive to reach medical facilities.

Observation:

• A 66-year-old male with a history of coronary artery bypass grafting sustained multiple traumas from a traffic accident.
• A small, contained rupture of the right ventricular outflow tract was identified.
• A false aneurysm developed at the rupture site within six months post-trauma.

Findings:

• The patient survived the initial trauma, which is unusual for cardiac rupture.
• Surgical resection of the false aneurysm was successfully performed.
• Pericardial adhesions from previous cardiac surgery were identified as a critical factor in the patient's survival.

Implications:

• This case underscores the potential life-saving role of prior cardiac surgery and resultant adhesions in managing acute cardiac trauma.
• It highlights a rare but survivable presentation of cardiac rupture, emphasizing the importance of advanced surgical interventions.
• The successful management of a false aneurysm following cardiac rupture offers insights into treating complex post-traumatic cardiac injuries.
