Project description:BackgroundLeft atrial appendage aneurysm (LAAA) is a rare condition mostly due to congenital malformations or secondary causes (i.e. mitral regurgitation).Case summaryWe present a case of a 47-year-old male with a history of atrial fibrillation treated with propafenone presented to our emergency department for palpitation and epigastric pain. The electrocardiogram showed atrial fibrillation at high ventricular rate and a new-onset left bundle branch block. Urgent coronary angiogram excluded coronary artery disease. Echocardiography and cardiac magnetic resonance revealed a giant LAAA. The electrocardiogram alterations were deemed secondary to aberrancy and treatment with class IC antiarrhythmic. The patient was discussed in the heart team, and considering his will to avoid surgery, he was managed conservatively with closed follow-up, anticoagulant and antiarrhythmic therapy, and internal loop recorder. At 1-year follow-up, he showed asymptomatic and without arrhythmias.DiscussionFew cases are described in the literature; therefore, there is uncertainty in treatment and prognosis. Diagnosis is achieved with multimodality imaging. Treatment can be surgical with aneurysmectomy or conservative with regular follow-up by imaging examinations and pharmacological therapy aimed to prevent complications such as thrombosis and arrhythmias. Since high-quality scientific data are lacking, shared decision-making is essential for the management of patients affected by LAAA. In our clinical case, our patient's will to not undergo surgery was considered, and therefore, a conservative management with strict follow-up and medications was chosen.

Surgical repair of an asymptomatic giant right coronary artery aneurysm.

Project description:Background Coronary artery aneurysm (CAA) is a rare finding, being mostly diagnosed on angiography or at autopsies. It is defined as being a dilation of the coronary artery that exceeds the diameter of the patient's largest coronary vessel by 1.5 to 2 times. Case Report We describe the operative correction of a giant right CAA measuring in excess of 10 cm. Conclusion Management of giant CAAs is not standardized and surgical strategy remains controversial. In our case, the patient has a successful surgical repair with no postoperative shunts on follow-up investigations.

Echocardiographic Features of Giant Right Atrial Diverticulum in a Dog.

Project description:A 12-year-old spayed female miniature Poodle presented for coughing, respiratory distress, and anorexia. After thoracentesis for pleural effusion, radiography revealed an enlarged cardiac silhouette with a bulge in the area of the body of the right atrium. Echocardiography revealed an anechoic chamber-like cavity lateral to the right atrium that communicated with the right atrium through a 13 mm defect in the right atrial free wall. Contrast echocardiography and color flow Doppler were used to prove that the cavity communicated with the right atrium. The cavity was diagnosed as a giant right atrial diverticulum.

An Asymptomatic Patient with an Additional Cardiac Chamber Giant Left Atrial Appendage.

Project description:We present the case of an asymptomatic 54-year-old male, referred to our department for a follow-up cardiological consultation. Echocardiography assessment showed an unknown cavity adjacent to the lateral wall of the left ventricle. A large left atrial appendage was revealed in further investigations, and the treatment option was proved to be an impasse.

A case of right atrial appendage aneurysm mimicking a pericardial cyst on echocardiogram.

Project description:Right atrial appendage aneurysms (RAAAs) are rarely encountered. If symptomatic, they present with atrial arrhythmias or embolic events. Surgical resection is indicated for symptomatic patients. We describe a 65-year-old man presenting with palpitation for 6 months. Electrocardiogram showed atrial flutter. Transthoracic echocardiography revealed a large thin-walled cystic mass anterior to right ventricular outflow tract, which was confirmed to be a giant RAAA by contrast transoesophageal echocardiography and later by contrast-enhanced computerised tomography. The patient underwent electrocardioversion, following which he remained in sinus rhythm and was asymptomatic during the 3 months follow-up period.RAAA can present with atrial flutter.Transoesophageal contrast echocardiography is the most valuable non-invasive tool in diagnosis of RAAA.Although computed tomography scan is not necessary for establishing the diagnosis, it may provide useful information regarding the structural anatomy.

A giant left atrial appendage aneurysm with recurrent chest tightness and atrial tachycardia: Multimodal imaging findings

Project description:Left atrial appendage aneurysm (LAAA) is a rare cardiac anomaly that is usually incidentally found in middle-aged patients. Though initially asymptomatic, LAAA can cause some serious complications: atrial tachyarrhythmia, thromboembolism, peripheral compression, and cardiac dysfunction. Multimodal imaging technologies, especially echocardiography and computed tomography (CT) scanning play an important role in the diagnosis of LAAA. Transthoracic echocardiography (TTE) is generally used for preliminary evaluation and diagnosis of the aneurysm. CT scanning can further confirm the diagnosis by demonstrating the spatial structure relationships and eliminating the possibility of other cardiac tumors. The following case study pertains to a 54-year-old patient with recurrent chest tightness and atrial tachycardia. The patient was diagnosed with a giant LAAA by multimodal imaging technology, and the aneurysm was surgically removed under cardiopulmonary bypass. After 4 years of follow-up, the patient reported living a healthy life without chest discomfort, complications, or medication. Multimodal imaging can provide important information for the diagnosis and treatment of left atrial appendage aneurysms, and aneurysm resection can be an effective therapeutic approach with a good long-term prognosis.
