“…A left ventricular (LV) pseudoaneurysm, or false aneurysm, is defined as a contained rupture or perforation of the myocardium [ 1 ]. The rupture of the myocardium occurs rarely in clinical practice; it is most often associated with myocardial infarction or cardiac surgery, such as mitral valve replacement (MVR), and is usually fatal [ 2 – 4 ].…”

We present a case of left ventricular pseudoaneurysm, which is a very rare and fatal complication of cardiac procedures such as mitral valve replacement. A 55-year-old woman presented to the Department of Thoracic and Cardiovascular Surgery at Hanyang University Seoul Hospital with chest pain. Ten years prior, the patient had undergone double valve replacement due to aortic regurgitation and mitral steno-insufficiency. Surgical repair was successfully performed using a prosthetic pericardial patch via a left lateral thoracotomy.

“…While a true aneurysm has nonrestrictive continuity with the LV cavity, a pseudoaneurysm has a defect in the myocardial continuity and a well-defined neck, representing a history of LV wall perforation [ 1 , 2 ]. Thus, such pseudoaneurysms are more likely to undergo rapid enlargement and rupture than true aneurysms [ 1 ].…”

“…The most common etiology of LV pseudoaneurysm is myocardial infarction (4). Inferior infarcts are approximately twice as common as anterior infarcts (5). One-third of pseudoaneurysms result from a surgical procedure, most often MVR (3).…”

Successful Resection of a Giant Left Ventricular Pseudoaneurysm Developed Later after Mitral Valve Replacement

et al. 2010

We present a case of successful surgical resection of a giant left ventricular (LV) pseudoaneurysm that developed 5 yr after mitral valve replacement (MVR). A 59-yr-old female was admitted with exertional chest pain radiating to left arm and back. 64-slice multidetector computed tomography (MDCT) revealed significant stenosis on the ostium of the first diagonal branch of the left anterior descending coronary artery and also a huge pseudoaneurysm compressing the right atrium and the inferior vena cava. She underwent resection of the pseudoaneurysm, and the pseudoaneurysm tunnel was repaired from the inside of LV cavity by removing the previously inserted prosthetic valve, followed by redo MVR together with coronary arterial bypass grafting (CABG) for a single-vessel disease. At the 6-month follow-up, the patient continued to do well without any complications.

“…The transmitral endocavitary approach for repair of LVPA has been previously reported in isolated cases. 3,4 This approach is particularly useful for patients with concomitant mitral valve disease that necessitates repair or replacement of the valve. With this approach, we gained a wide exposure of the aneurysm neck and were able to achieve an excellent repair with restoration of left ventricular geometry while avoiding a ventriculotomy.…”
