Penetrating cardiac injuries are rare, but often fatal. They may present with different manifestations. A 30-year-old male patient was
admitted with self-inflicted left parasternal stab wound in the second intercostal space. Computed tomography revealed pericardial
and pleural effusion. Echocardiography and aortography showed severe aortic regurgitation and aorto-right ventricular communication
mimicking a congenital sinus Valsalva aneurysm rupture. The patient was operated and aortic leaflet repair with a pericardial patch and
closure of the communication on both aortic and right ventricular sides were performed. In conclusion, although such traumatic injuries
are rare, they may be life-threatening and, therefore, requires prompt treatment. |

Penetrating cardiac injuries are rare, but represent a
high mortality in most cases. The injury is usually nonaccidental,
predominantly sustained by males, and the
mortality rate is about 60%, which further increases
where pericardial tamponade is absent.[1,2] In a recent
large series, 86% of injuries constituted single chamber
injury, predominantly right ventricle (46%) and left
ventricle (24%), whereas multi-chamber injuries were
seen in 18% of cases. Patients typically manifest with
signs of cardiac tamponade, cardiac arrest, or signs of
extremis from exsanguination.[2] Congenital sinus Valsalva aneurysms are rare abnormalities often presenting with rupture. In more than 80% of cases, the rupture originates from the right coronary sinus (RCS). Aorto-right ventricular connection is observed in 65% of cases.[3,4] Herein, we report a case of aorto-right ventricular communication concomitant with aortic regurgitation due to self-inflicted stab wound injury. |

CASE PRESANTATION
|
|
A 30-year-old male patient was admitted to the
cardiology department with chest pain. He had a selfinflicted
left parasternal stab wound in the second
intercostal space two days ago after heavy alcohol
intake. He did not remember the type of knife used. He was examined in a rural medical center and
the skin wound was sutured. The patient reported
no complaint subsequently. Echocardiography and
aortography revealed aortic valve regurgitation due
to a defect in the right coronary cusp (RCC) and
aorto-right ventricular communication (Video 1).
Pericardial and bilateral pleural effusion was noted
on echocardiography and computed tomography (CT)
scan (Figure 1a). He had no signs of tamponade or
pathological findings, except for the sutured wound
(Figure 1b). He was scheduled for an urgent operation and a written informed consent was obtained. A median sternotomy was performed. Due to the possibility of aortic injury, right femoral artery was cannulated to initiate cardiopulmonary bypass (CPB) immediately following pericardiotomy. Hematoma and defibrinated blood were present in the pericardial space. A very little adventitial hematoma was located in the left lateral side of the aorta above the sinotubular junction. The right atrium was cannulated and CPB was initiated. Transverse aortotomy was performed. There was a slit-like linear opening on RCS connected with right ventricular cavity (Figure 1c). There was also a 2¥1 cm defect in the RCC. Transverse right ventriculotomy was performed to visualize the opening of the defect and a slit-like linear opening was noted (Figure 1d). The aortic side of the opening was sutured with two Teflon pledgeted sutures (Figure 1e) and the right ventricular side with the Teflon felt on both sides (Figure 1f). The defect in the RCC was repaired with a fresh pericardial patch. Aortotomy was closed and the patient was weaned from CPB. The postoperative course was uneventful and postoperative echocardiography revealed no aortic regurgitation or aorto-right ventricular communication. In the first year of follow-up, the patient is still stable with normal echocardiographic findings. |

Penetrating cardiac injury is often fatal with a
mortality rate over 60%. Multi-chamber injuries
constitute a lower percentage of cases with a
predominant single right ventricle injury.[1,2] The
present case is unique, as it is a late admission
and had no signs of hemodynamic compromise, despite a great injury with an aorto-right ventricular
communication. Such an injury might have caused a great hemodynamic compromise due to signs of exsanguination or cardiac tamponade. However, our case had no complaints at the time of injury and was admitted two days later due to chest pain. Surprisingly, pericardial effusion was not much and did not cause tamponade within two days. There was a small adventitial hematoma in the left lateral side of the aorta, however, there was neither hemorrhage from the aorta nor a visible aortic injury site. In this case, the injury mimicked a ruptured congenital sinus Valsalva aneurysm, although it was truly a multichamber injury involving the ascending aorta. The RCC was also injured and repaired with a pericardial patch. There is a limited number of reports in the literature showing similar pathologies.[5,6] Such an injury may be fatal at the time of injury, and it is quite surprising that our patient survived. In addition, he did not remember the type of knife used, although we suspected a skewer-like thin and long tool. In conclusion, penetrating cardiac injuries may represent as unique pathologies and require major interventions. If possible, repair should be preferred, if valvular pathologies exist.
