Project description:BackgroundPericardial effusion is a common complication of percutaneous left atrial appendage (LAA) closure. Acute management is the cornerstone of pericardial effusion treatment and interrupting the intervention is often required.Case summaryA 65-year-old man presented an acute 10 mm pericardial effusion following pigtail contrast appendage injection. A rapid Watchman Flex 24 mm (Boston Scientific) deployment permitted bleeding interruption. A needle pericardiocentesis was achieved in order to prevent any haemodynamical instability.DiscussionThis case report describes an atypical cause of pericardial effusion and a technique for bleeding control with LAA closure device deployment.

Supramitral membrane with left atrial appendage thrombus: A rare entity.

Project description:A 4-year-old child with supramitral membrane (SMM) causing severe mitral stenosis (MS) was taken for excision of the membrane. Intraoperative transesophageal echocardiography showed a large thrombus in the left atrial appendage (LAA) in addition to SMM. The case underscores the importance of this extremely rare association and prompt therapy to prevent catastrophic consequences.

Left atrial appendage occlusion.

Project description:Prevention of stroke represents a goal of primary importance in health systems due to its associated morbidity and mortality. As several patient groups with increased stroke rates have been identified, multiple approaches have been developed and implemented: oral anticoagulation (OAC) for patients with atrial fibrillation, surgical and percutaneous revascularisation in patients with carotid disease, device closure for patients with patent foramen ovale, and now, left atrial appendage occlusion (LAAO) for selected patients with non-valvular atrial fibrillation (NVAF). The latter group of patients are the focus of this review which evaluates the pathophysiology, selection of patients, procedural performance, outcomes of treatment both during and post-procedure, adjunctive therapy, complications, and longer-term outcomes.

Giant aneurysm of the left atrial appendage: a case report.

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.
