Complications of LV aneurysm – Cardiology MCQ – Answer
Which of the following is the least likely complication of left ventricular aneurysm? Correct answer: 4. Rupture and cardiac tamponade
Recurrent ventricular tachycardia occurs due to reentrant circuits in the viable microchannels at the border zone of the aneurysm. Left ventricular failure occurs due to wasted systolic effort at the dyskinetic region. Mural thrombus occurs due to stasis in the aneurysm, and the ischemic damage to the endocardium,
Secondary rupture is least likely, unlike in pseudoaneurysm where secondary rupture is imminent as it is covered only by the pericardium. True aneurysm has all the three layers, though thinned out. Pseudoaneurysm is actually ventricular free wall rupture sealed off by the pericardium.
