A Rare Presentation of a Large Left Atrial Myxoma with Gastrointestinal Symptoms.

Atrial myxoma is a rare primary tumour of the heart that typically arises from the left atrium. Patients typically present with obstructive symptoms such as dyspnoea, but constitutional and embolic symptoms can be seen as well. Gastrointestinal symptoms in the absence of embolisation are rarely reported in the literature. Our case presents a 55-year-old female who was found to have a large left atrial myxoma after presenting with gastrointestinal symptoms, which resolved upon resection of the tumour. This case illustrates that atrial myxomas can have an atypical presentation with gastrointestinal symptoms, which could be related to inflammation of gastric mucosa from interleukin-6 produced by the tumour cells. Careful history-taking followed by early detection and prompt treatment is important as atrial myxomas can lead to potentially devastating complications. LEARNING POINTS: Atrial myxomas are primary tumours of the heart that can present with a wide spectrum of symptoms.Early consideration and recognition of atypical presentations of atrial myxomas can be crucial in preventing serious consequences such as cardiac arrest.

A Novel Technique Debulking Vegetations in Tricuspid Endocarditis and Venacava Utilizing AngioVac Aspiration System.

The AngioVac system (AngioDynamics Inc., Latham, NY) is used for the removal of commonly encountered intravascular material, such as thrombus or vegetations in the right atrium, right ventricle, superior vena cava, and inferior vena cava. Patients with high surgical risk having tricuspid endocarditis and superior vena cava thrombus can be treated with the AngioVac system, hence mitigating the risks for this patient population. We present a case series with the utilization of the AngioVac device to reduce the vegetation size and decrease the risk of emboli with effective antibiotic penetration. Transesophageal echocardiography shows a reduction in the size of the vegetations in all three cases with no postoperative complications. This case series demonstrates a novel technique debulking vegetations in tricuspid endocarditis and vena cava.

Covaxin-Induced Lymphocytic Myocarditis.

We report the case of a young adult male with endomyocardial biopsy-proven lymphocytic myocarditis following Covaxin administration. Covaxin differs from the mRNA vaccines in that it is an inactivated virus developed using the whole virion inactivated using the Vero cell platform. We successfully managed the patient with complete resolution of symptoms.
