This case highlights the importance of continued clinical and echocardiographic vigilance after severe blunt cardiac injury, particularly for detecting late-emerging structural complications such as aneurysm formation and valvular dysfunction, and illustrates the potential utility of VA-ECMO as a bridging strategy before surgical repair of traumatic cardiac rupture.
Key Findings
Case Report
A patient developed rupture of a posterior left ventricular aneurysm 54 days after a fall from a height.
The authors describe a temporal sequence from blunt myocardial contusion to left ventricular aneurysm formation and rupture.
The rupture was delayed, occurring 54 days after the initial trauma.
The authors describe delayed traumatic cardiac rupture complicated by secondary tricuspid chordae tendineae rupture as an exceedingly rare clinical entity.
Case Report
The patient was emergently supported with VA-ECMO and then underwent surgical repair of the aneurysm.
VA-ECMO was placed emergently for circulatory support.
Surgical repair of the aneurysm followed the ECMO support.
The authors state this illustrates the potential utility of VA-ECMO as a critical bridging strategy to stabilize patients with traumatic cardiac rupture before surgical repair.
Case Report
Postoperative echocardiography revealed new-onset tricuspid chordae tendineae rupture, and the patient underwent elective mechanical tricuspid valve replacement.
The tricuspid chordal rupture was detected after the aneurysm repair.
The authors state that, to their knowledge, this is the first report documenting delayed left ventricular aneurysm rupture followed by tricuspid chordal rupture after surgical repair.
Management was elective mechanical tricuspid replacement.
Case Report
Histopathology of the resected tricuspid valve tissue showed chronic degenerative changes.
Histopathological examination was performed on the resected valve tissues.
The chronic degenerative findings were noted in the context of a proposed link to the earlier trauma and aneurysm.
Conclusions
The causal relationship and mechanism linking aneurysm repair or rupture to tricuspid chordal rupture remain uncertain, though the authors propose a potential pathophysiological connection.
The authors note a temporal association between aneurysm repair and subsequent tricuspid chordal rupture.
They state that the precise mechanism remains to be determined.
This is a single case report, so causality cannot be established.
Conclusions
The authors conclude that clinicians should maintain clinical and echocardiographic vigilance after severe blunt cardiac injury to detect late-emerging structural complications.
Late complications highlighted include aneurysm formation and valvular dysfunction.
The case shows complications emerging weeks after the initial trauma (54 days to aneurysm rupture).
What This Means
This case report describes a patient who suffered a serious blunt injury to the heart after a fall from a height. Fifty-four days later, a weakened bulge (aneurysm) in the back wall of the left ventricle ruptured. The patient was placed on VA-ECMO, a machine that temporarily takes over heart and lung function, and then had the aneurysm surgically repaired.
After surgery, heart ultrasound showed that the cord-like supports of the tricuspid valve had newly ruptured, so the patient had the valve replaced with a mechanical one in a planned operation. Examination of the removed valve tissue showed long-standing degenerative changes. The authors believe this is the first report of this sequence of events, but they could not determine whether the aneurysm, its rupture, or its repair caused the valve problem.
This research suggests that people who have had severe blunt heart injuries may need follow-up heart imaging for some time afterward, since complications can appear weeks later. It also suggests ECMO can serve as a bridge to surgery in such emergencies. Because this is a single case, these observations cannot prove cause and effect or show how often such events occur.
