“…The benefits of surgery outweigh the risks of rupture in almost all cases. Previous studies suggest that conservative management can be considered in asymptomatic patients with small aneurysms (less than 3 cm of dimension) or increased surgical risk [10 , 11] .…”

A left ventricle pseudoaneurysm (LV PSA) is defined as a free wall rupture of the left ventricle contained by the adjacent pericardial tissue. This rare complication is most commonly encountered following myocardial infarction, trauma, or infection. Surgery is typically warranted to avoid progression to spontaneous rupture, which may potentially lead to cardiac tamponade and death. Cardiac magnetic resonance imaging is the modality of choice to characterize left ventricle morphology and function. Accurate distinction between a pseudoaneurysm and a true aneurysm is crucial, since management and prognosis are significantly different between these 2 entities. We present a case of a 63-year-old male heart transplant recipient, admitted for suspicion of acute cellular rejection, with an unexpected finding of a LV PSA.

“…A previous report noted that the mortality of LV pseudo-aneurysm is considered to be higher after conservative therapy, so it should be actively treated with surgery (6). On the other hand, some retrospective studies have reported that cases involving chronic small LV pseudo-aneurysms of ＜3 cm in size or patients with high surgical risk can be managed conservatively (7). However, rapidly progressive LV pseudo-aneurysm has also been reported (8), even in the case of conservative therapy, periodic follow-up echocardiography is mandatory.…”

We report a case with the simultaneous occurrence of pseudo-aneurysm of the left ventricle and ventricular septal rupture, which was successfully surgically repaired. A 77-year-old woman with a history of aortic valve replacement and coronary bypass graft presented to our clinic due to chest pain. She was diagnosed with anterior ST-segment elevation myocardial infarction (STEMI) based on an electrocardiogram. Echocardiography revealed pseudo-aneurysm of the left ventricle and ventricular septal rupture. Coronary angiography revealed 99% stenosis with delayed contrast filling in the mid left anterior descending artery. Surgical repair with a bovine pericardium patch was performed, and the postoperative course was uneventful.

“…6 It has been estimated that significant LV pseudoaneurysms occur in 0.8% of cases after mitral valve replacement (MVR), 7 which is about eight times more often than that after myocardial infarction. 8 We report our experience with a patient with an LV pseudoaneurysm after MVR.…”

Left ventricular pseudoaneurysm is a partial cardiac rupture, contained by the surrounding pericardium that maintains communication with the left ventricular lumen. Whereas most cases of left ventricular pseudoaneurysms are related to myocardial infarction (loss of myocardial integrity), only a handful are associated with valve surgery. We present a female patient, who was admitted for elective mitral valve replacement. After the implantation of the mechanical valve, we encountered a rupture of the atrioventricular groove. After 3 months, a left ventricular pseudoaneurysm was found and the patient was reoperated. The valve was explanted and the inspection of the annulus and previously implanted pericardial patch revealed a loosened stitch on the inferior (ventricular) side. The defect was reinforced with additional stitches and the valve was reimplanted. In conclusion, we report an unusual case with two serious complications after mitral valve replacement – atrioventricular groove rupture and left ventricular pseudoaneurysm.
