Ventricular restoration in adults with huge congenital left ventricular aneurysm: report of two cases.

Congenital ventricular aneurysms (CVA) are rare cardiac anomalies that have been predominantly described in the Black population. They are characterized by an akinetic ventricular protrusion that is commonly located at the basal and apical segments. Although the diagnosis is often incidental and the majority of patients are asymptomatic, life-threatening events such as persistent ventricular arrhythmias, CVA rupture, and heart failure are not uncommon. However, no standardized therapy is currently available and good outcomes have been reported with both conservative and surgical management. We report the cases of two young Black African patients with huge symptomatic CVA lesions who underwent successful surgical repair with a ventricular restoration technique. Both cases were consulted for chest pain and dyspnea. Chest X-ray and transthoracic Doppler echocardiography suggested the diagnosis. Thoracic angioscanner and thoracic magnetic resonance imaging confirmed the diagnosis. Both patients underwent successful surgery. This case report aims to revisit the diagnostic and therapeutic approach to this rare pathology, in our professional environment.

Congenital Sub-Mitral Aneurysm: Anesthetics and Surgical Management.

ABSTRACT: A sub-mitral left ventricular aneurysm is a rare condition. It is a congenital outpouching of the left ventricular wall, invariably occurring adjacent to the posterior mitral leaflet. Sub-mitral aneurysm (SMA) has usually been reported as a consequence of myocardial ischemia (MI), rheumatic heart disease, tuberculosis, and infective endocarditis. Nevertheless, there have been few case reports of congenital SMA in India. It usually presents with symptoms of heart failure. We report a rare case of congenital SMA in a 27-year-old young Indian and its successful management through a trans-aneurysmal approach.

In Utero Presentation of Left Ventricular Aneurysm.

Congenital left ventricular aneurysm, pseudoaneurysm, and diverticulum are rare entities. These diagnoses can be made pre- and/or postnatally. Although these entities overlap clinically and morphologically, important distinctions can allow for accurate diagnoses. Appropriate diagnosis can be imperative for risk stratification and guidance of prenatal and postnatal management. The case described in the present report highlights a challenging case of a fetal left ventricular aneurysm, management during the prenatal and postnatal periods, and important differentiating features from a ventricular diverticulum and pseudoaneurysm.

Heart in Heart: A Case Report of Giant Left Atrial Appendage Aneurysm.

Left atrial appendage aneurysm (LAAA) is a rare cardiac anomaly. The cause mostly due to congenital, but can be acquired also. Patient may remain asymptomatic or may present with variable symptom. It can predispose to hazardous adverse events, including atrial fibrillation, myocardial infarction, cardiac dysfunction and life-threatening systemic thromboembolism. Simple imaging, electrocardiography and echocardiography can diagnose this rare cardiac anomaly. We are reporting a case who presented to us at 5 years of age with palpitation, chest pain and dizziness with arrythmia that developed one month back; he visited our outpatient department of the National Heart Foundation Hospital & Research Institute Hospital, Dhaka, Bangladesh on 13th February 2020. We diagnosed left atrial appendage aneurysm with mitral valve prolapse with atrial arrhythmia thereafter surgical resection of aneurysmal part along with mitral valve annuloplasty done by mid sternotomy and maze therapy. Postoperative period was uneventful and discharged after 6th post operative day.

Giant right atrium, what does it hide? Case presentation.

BACKGROUND: Malformation of the right atrium is a rare cardiac abnormality and is usually reported as isolated malformation in the literature. CASE PRESENTATION: Prenatal giant atrial dilatation in an asymptomatic infant was treated surgically at 18 months of age, due to potential risk of thrombosis and arrhythmias. Post-surgical echocardiographic images illustrate residual atrial elevated pressure. CONCLUSIONS: Sometimes, as seems in our case, right atrial dilatation hides an associated restrictive right ventricle.

An 8-Year-Old Boy With a Giant Left Atrium.

CASE PRESENTATION: An 8-year-old boy was referred to our institution because of nausea and vomiting for 1 day. He had also been experiencing shortness of breath for more than 1 year. This symptom had progressed so that he could no longer run or walk upstairs without chest discomfort. There was no associated fever, diarrhea, or coughing. He had a history of heart murmur that was diagnosed in another clinic 4 years ago. Echocardiogram 4 years prior suggested mild to moderate biatrial enlargement with trivial mitral valve regurgitation. He did not go in for any follow-up until this admission. He had no other associated diseases, nor use of medicine.

Congenital left ventricular aneurysm with myocardial noncompaction pattern.

Congenital left ventricular aneurysm or diverticulum is very rare. Most congenital left ventricular aneurysms are asymptomatic but some cause systemic embolization, left ventricular free wall rupture, or ventricular arrhythmias causing sudden cardiac death. A 29-year-old woman with congenital left ventricular aneurysm and nonsustained ventricular tachycardia underwent surgical plication of the aneurysm with left ventricular reshaping to improve heart failure symptoms, prevent rupture of the aneurysm wall and the possibility of thrombus formation, and excise the fibrotic tissue of the left ventricular aneurysm, which could be a trigger for left ventricular aneurysm arrhythmias. The postoperative course was unremarkable.

Surgical Management of Congenital Bilateral Multiple Atrial Aneurysms.

Congenital atrial aneurysms are a rare malformation, often associated with supraventricular arrhythmias. Here, we present the case of a child with biatrial aneurysms and a type 2 atrioseptal defect. Directly after birth the girl became symptomatic with incessant ectopic atrial tachyarrhythmia. On echocardiography, multiple biatrial aneurysms and septations were observed. The diagnosis was confirmed with computed tomography. After 7 months of antiarrhythmic therapy, the child underwent surgical intervention by aneurysm resection, atrioseptal defect closure, and ablation. Since then the patient has been in stable sinus rhythm.

Congenital right ventricular aneurysm with characteristics of a pseudoaneurysm.

We report a case of an isolated congenital right ventricular outpouching detected incidentally on foetal echocardiogram that was performed due to suspicion of CHD. Subsequent echocardiogram after birth revealed an aneurysm with features of a pseudoaneurysm having a thin and hypokinetic wall connected to the ventricle's cavity via a narrow neck. This pseudoaneurysm appears to be stable in size and of no clinical significance during the short-term follow-up.

Coil occlusion of a congenital left ventricular aneurysm in a newborn.

We report interventional treatment of a congenital left ventricular aneurysm in a neonate. The aneurysm was detected prenatally at 20 weeks of gestation. Postnatally, the aneurysm increased in size during the first few days of life and therefore we opted for interventional closure to abolish the potential risk of rupture. The aneurysm was entered with a 2.7 French microcatheter, and complete occlusion was achieved by successive placement of three detachable large volume coils (Ruby Coil PenumbraR , Alameda, California). To the best of our knowledge, this is the first report describing interventional occlusion of a congenital ventricular aneurysm in early infancy. Interventional occlusion with detachable large volume coils appears to be an attractive alternative to surgical resection in patients presenting with ventricular outpouchings and narrow base connection to the ventricle.

Isolated Congenital Right Atrial Aneurysm: Monitoring Parameters for Asymptomatic Patients.

Isolated congenital right atrial aneurysm is rare. Indications for surgery in asymptomatic patients with moderate-size right atria remain controversial. Evidence in support of medical management and timing of prophylactic surgery is reviewed. We propose the use of three echocardiographic indices to help identify inappropriate atrial growth and facilitate surgical decision-making.

Congenital aneurysm of the left atrium associated with double-outlet right ventricle in a trisomy-18 fetus: Case report and literature review.

Congenital aneurysm of the left atrium is a rare cardiac anomaly, most commonly detected between the 2nd and 4th decades of life in a symptomatic patient. We report a congenital aneurysm of the left atrium diagnosed at 24 weeks of gestational age, associated with other congenital heart diseases and 47XY, +18 karyotype. The literature of the left atrial aneurysm diagnosed by fetal echocardiography is also reviewed in this report.

An atrial septal aneurysm with an organized thrombus in an asymptomatic patient: A case report.

INTRODUCTION: An atrial septal aneurysm (ASA) is a rare congenital cardiac deformity characterized by interatrial septum protruding into atria forming a saccular structure. PATIENT CONCERNS: In our case, a 42-year-old female patient presented to our hospital complained of palpitation. DIAGNOSIS: Transthoracic echocardiography detected a 3.4 × 3.4 cm circular mass attached to the interatrial septum in right atrium complicated with a 6 mm secundum atrial septal defects (ASD). INTERVENTIONS: The patient received a cardiopulmonary bypass surgery to remove the mass and close the ASD. OUTCOMES: The mass turned out to be an organized thrombus with calcium deposition and fibrinoid necrosis. CONCLUSION: ASA is a potential location of atrial thrombus because of the stagnation of blood. Systemic embolism events are the main complications of ASA. Surgery or anticoagulation is both recommended in patients with ASA with thrombus.

Asymptomatic giant congenital left atrial aneurysm.

Yakut K, Varan B, Erdogan I. Asymptomatic giant congenital left atrial aneurysm. Turk J Pediatr 2019; 61: 117-119. Congenital aneurysm of the left atrial appendage can be caused by congenital dysplasia of the pectinate muscles and may be accompanied by a congenital absence of the pericardium. Symptoms generally manifest after two decades and the most common symptom is atrial arrhythmia in the form of atrial fibrillation / flutter. A four year-old patient with no symptoms underwent an echocardiographic examination for the investigation of a heart murmur. Echocardiographic examination revealed a large cystic lesion occupying the left hemithorax and compressing the left ventricle. The patient was referred to our center. The lesion caused displacement of the heart rightward behind the sternum which made the examination difficult. We aimed to present this rare case of giant left atrial appendage aneurysm in the light of current literature.

Congenital Aneurysm of the Right Atrium: Two Cases Report.

Congenital aneurysm or enlargement of the right atrium is a rare condition. Two children operated on at the age of 14 months and 11 years old for congenital aneurysm of the right atrium are reported. Both presented cardiomegaly and symptoms of paroxysmal supraventricular tachycardia. Diagnosis was established by echocardiography. Surgical resection was successful. Both patients are free of symptoms and their chest X-ray and echocardiogram are normal. The first patient is now in her 17th postoperative year. The patients' evolution suggests that the surgery is a curative procedure.
