Insights
Traumatic heart wounds can cause complex lesions like mitral regurgitation and aorto-left atrial fistulas. Surgical repair of these cardiac injuries, even decades later, can yield good functional results.
Area of Science:
- Cardiology
- Cardiac Surgery
- Trauma Surgery
Background:
- Penetrating cardiac trauma can lead to delayed complications.
- Valvular regurgitation and intracardiac fistulas are known sequelae.
- Cardiac failure may manifest years after the initial injury.
Observation:
- A case of a patient with severe cardiac failure is presented.
- The patient had mitral and aortic regurgitation with an aorto-left atrial fistula.
- These complex cardiac lesions resulted from a penetrating wound sustained over 20 years prior.
Findings:
- The study highlights a rare case of delayed presentation of cardiac lesions post-trauma.
- Surgical intervention successfully repaired the valvular regurgitation and aorto-left atrial fistula.
- Complete repair resulted in a good functional outcome for the patient.
Implications:
- This case underscores the importance of long-term follow-up for patients with penetrating cardiac injuries.
- It demonstrates the feasibility and efficacy of surgical repair for complex, delayed cardiac lesions.
- Understanding diverse cardiac injury presentations is crucial for timely diagnosis and treatment.
Abstract:
Penetrating wounds of the heart, when not immediately fatal, may give rise to complex lesions associating valvular regurgitations and fistulous connections. The authors report the case of a patient with mitral and aortic regurgitation associated with an aorto-left atrial fistula of traumatic origin and causing invalidating cardiac failure. The interest of this particular case lies in the duration of the interval between the causal trauma and the appearance of symptoms (over 20 years). Complete surgical repair of the lesions provided a good functional result. The authors discuss the different types of lesions which may be caused by wounds of the heart and their modes of presentation.

The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
