Pseudoaneurysm Of Left Ventricle Research Articles

EComment. Left ventricle pseudoaneurysm secondary to infective endocarditis

In the interesting case report presented by Singh et al. [1], the patient underwent a successful aneurysmorrhaphy four months after a blunt non-penetrating chest injury. What is remarkable in their report is that the authors make no allusion in their discussion to a previous and well-known aetiology of left ventricle pseudoaneurysm which is infective endocarditis. We [2] and others [3] have published case reports about false aneurysm arising from the left ventricle in patients with infective endocarditis. Myocardial abscess, pseudoaneurysm of the ventricle and cardiac rupture rarely complicate infective endocarditis. Presentation can vary from pericardial effusion to cardiac tamponade occurring in association with annular abscess or myocardial perforation [4]. Formation of a myocardial abscess may be secondary to multiple coronary septic emboli or to local spread from the infected endocardium to the nearby myocardium. Rupture of the myocardial abscess is often fatal, but when the rupture is contained by scar tissue, this entity is known as a post-infective endocarditis pseudoaneurysm. As long as the pseudoaneurysm remains contained, the haemodynamic state will remain good but the chances of survival without surgery remain slim [5]. Conflict of Interest: None declared

Post-myocardial infarction giant left ventricular pseudoaneurysm presenting with severe heart failure

Left ventricle (LV) pseudoaneurysm is a late mechanical complication of myocardial infarction. A giant LV pseudoaneurysm is a rare presentation. We report a case of giant LV pseudoaneurysm in a post-MI patient who presented with gross congestive heart failure. The patient had a successful surgical repair of the aneurysm and had a favorable 3-mo outcome. The imaging modality and surgical treatment of the pseudoaneurysm are discussed.

Ventricular septal defect, developed due to the coronary artery injury after blunt chest trauma in childhood

In the literature, cardiac response associated with blunt chest trauma in children has been reported generally as case reports, and interventricular septal rupture due to trauma is quite rare. Interventricular septal rupture can develop even in the absence of visible signs of a trauma because of the flexibility of the chest structure in children. In the present case, a seven-year-old boy with interventricular septal rupture at the mid-muscular region and left ventricle pseudoaneurysm developed due to injury to the left anterior descending coronary artery after a traffic accident is reported. Patients with cardiac murmur detected on physical examination after a blunt chest trauma must be considered as cardiac injury, and in those with signs of ischemia detected on electrocardiography, it should not be forgotten that the coronary artery may be affected.

Clinical Experience With Percutaneous Left Ventricular Transapical Access for Interventions in Structural Heart Defects: A Safe Access and Secure Exit

This study sought to evaluate the safety of percutaneous direct left ventricular access for interventional procedures. Experience with percutaneous access of the left ventricle (LV) for interventional procedures has been limited and associated with a high percentage of major complications. We report our clinical experience with percutaneous direct LV access for interventional procedures. Between March 2008 and December 2010, there were 32 percutaneous transapical punctures in 28 consecutive patients (16 males, mean age 68.2 ± 10.8 years). The delivery sheath sizes ranged from 5- to 12-F. All transapical punctures were successfully performed, and safe closure of the access sites was achieved. Total procedural time was 153.6 ± 49.4 min for procedures converted from conventional approaches to a transapical approach, 129.5 ± 29.6 min for the transapical approach with trans-septal rail support, and 109.3 ± 41.4 min for the planned transapical approach. Fluoroscopy time was 61.3 ± 26.1 min, 29.7 ± 20.8 min, and 27.4 ± 21.4 min, respectively. Fluoroscopy time for closure of mitral paravalvular leaks was reduced by 35%, from 42.6 ± 29.9 min to 27.4 ± 15.6 min. Complications were observed in 2 patients (7.1%). With meticulous planning, transapical puncture is safe. The transapical access provides a more direct approach to the LV targets for intervention and leads to a significant decrease in the procedural and fluoroscopy times. Device closure of the direct LV access site is a reliable and safe method of hemostasis. Placement of a closure device should be considered if sheaths larger than 5-F are used. Although we used this technique only for paravalvular leak and LV pseudoaneurysm closure, it may have application for other percutaneous structural heart interventions.

Second successful surgical ventricular reconstruction: a cardiac magnetic resonance imaging illustration

This case reports a magnetic resonance imaging (MRI) illustration of a successful ventricular reconstruction of a left ventricle pseudoaneurysm that developed four months after postmyocardial infarction ventricular repair. Thus, preoperative non-invasive MRI techniques are valuable diagnostic tools in this setting. Indeed, the present case shows that MRI greatly helped in the management and surgical decision-making.

Spontaneous closure of a left ventricle pseudoaneurysm following apical venting

Cardiac surgery is the second most frequent aetiology of left ventricular pseudoaneurysm (LVP). Left ventricular apical venting is a recognized cause of LVP. Prompt surgical treatment is usually needed since there is a high risk of rupture and spontaneous closure is very rare. We describe a case of spontaneous closure of a left ventricle pseudoaneurysm following apical venting.

Left ventricular lipoma with pseudoaneurysm-like appearance

We describe an extremely rare cardiac lipoma, with electrocardiographic changes in ST segments and T waves, suggesting ischemic heart disease. The abnormal electrocardiogram was identified during a routine physical examination of an asymptomatic 57-year-old man. Coronary angiography showed no stenotic or occlusive lesions in the coronary arteries except that the left anterior descending artery followed a winding course in the apical region. Left ventriculography revealed a pseudoaneurysm-like mass around the apical portion. Computed tomography and magnetic resonance imaging revealed a cardiac lipoma that communicated with the left ventricle and resembled a pseudoaneurysm. After complete resection of the lipoma and left ventricle patch plasty, the postoperative course was uneventful. Histologically, the tumor was an intramyocardiac lipoma with no evidence of malignancy. To our knowledge, we are the first to describe an intramyocardiac lipoma resembling a left ventricle pseudoaneurysm.

Initial Presentation of an Accessory Left Ventricle in a Patient With Syncope

A 39-year-old woman was referred for a transthoracic echocardiogram after presenting to her primary care provider following an episode of unexplained loss of consciousness. Her past medical history was notable for fibromyalgia and migraine headaches. She had a normal cardiac and neurological physical examination with no extra heart sounds or murmurs. Her transthoracic echocardiogram (Movie I of the online-only Data Supplement) revealed a large outpouching of the lateral wall of the left ventricle (LV) that contracted in synchrony with the ventricle (Figure 1A and 1B). The initial differential for this finding included an LV diverticulum or an accessory ventricle. An LV pseudoaneurysm was considered unlikely because of the synchronous contraction of the outpouching with the rest of the ventricle. Figure 1. Transthoracic echocardiogram demonstrating the apical 4-chamber view of the LV. The outpouching (arrow) originating from the lateral aspect of the midventricular wall is shown in both diastole (A) and systole (B). The outpouching contracted synchronously with the LV. To further evaluate this …

Percutaneous Device Closure of Iatrogenic Left Ventricular Wall Pseudoaneurysm

A 67-year-old man with ischemic cardiomyopathy was transferred to our hospital in cardiogenic. During a video-assisted mini-thoracotomy for left ventricular epicardial lead implantation, a left ventricular free-wall rupture occurred and an emergency surgical repair was performed. Postoperatively patients experience left ventricular wall pseudoaneurysm. After stabilization of clinical conditions with aggressive medical treatment, we decided to attempt a minimally invasive procedure (ie, a transcatheter pseudoaneurysm closure). To date, few cases of device closure of left ventricle pseudoaneurysm are reported in the literature, usually secondary to myocardial infarction, and we believe this is the first case of left ventricle pseudoaneurysm after iatrogenic left ventricle laceration and surgical closure.

Successful embolization of a left ventricular pseudoaneurysm after perventricular ventricular septal defect device closure

Perventricular device closure has become an important management adjunct for ventricular septal defects deemed inoperable and difficult to address in the catheterization laboratory. Complications directly related to the procedure are rarely reported, and all have been manifest in the periprocedural period. We present the case of a 6-week-old boy who underwent perventricular closure of a muscular ventricular septal defect and had a left ventricle pseudoaneurysm identified 10 months later during catheterization to close residual septal defects. We describe the subsequent percutaneous coil embolization of the pseudoaneurysm and clinical follow-up.

An Unusual Presentation of a Large Left Ventricular Pseudoaneurysm

Left ventricle pseudoaneurysm is an infrequent complication of myocardial infarction, and is most commonly localized in the inferoposterior left ventricular segments. We describe a patient post anterior myocardial infarction, who presented with pulmonary edema and a large pseudoaneurysm of the anterolateral wall with involvement of the anterolateral papillary muscle, resulting in severe mitral regurgitation. The patient underwent successful operation and is currently well.

Repair of Delayed Left Ventricular Rupture After Mitral Valve Replacement: Report of a Case

Rupture of the left ventricle (LV) after mitral valve replacement (MVR) is a devastating complication, associated with high mortality. A 64-year-old woman with a type I delayed LV rupture, which occurred after MVR with a 27-mm St. Jude Medical mitral prosthesis for mitral stenosis, was successfully treated by a combination of intracardiac and extracardiac surgical repair techniques. The extracardiac repair involved approximating the edges of myocardium around the tear with large sutures bolstered by strips of Teflon felt, then covering the epicardial hematoma with another porcine pericardial patch, using gelatin resorcinol formaldehyde glue and collagen sheets. The intracardiac repair involved suturing the edges of an oval piece of porcine pericardium to the endocardium around the laceration. No LV pseudoaneurysm was detected postoperatively on echocardiography or computed tomography scans. The patient is well 2 years after the operation.
