Acute myocardial infarction caused by left atrial myxoma: Role of intracoronary catheter aspiration

Massive left atrial myxoma leading to recurrent cerebrovascular accidents (CVAs) in a young woman: A case report

Myxomas are tumors that occur due to uncontrolled proliferation of mesenchymal cells. Cardiac myxomas although very rare, are still the most common primary tumor of heart. Cardiac myxomas have a prevalence of 0.03% in the general population. They can have a variety of clinical presentations with obstructive cardiac symptoms, constitutional symptoms and symptoms due to embolism to other body parts chief among them. CNS embolism with stroke is among the rarest clinical presentation of cardiac myxomas. Our article portrays a case of cardiac myxomas that initially resulted in episodes of dyspnea and syncope and eventually led to recurrent episodes of transient ischemic attack and stroke. Case was confirmed by transesophageal echocardiography and managed surgically by medial sternotomy. Myxoma, a benign primary cardiac tumor is itself a rare occurrence, embolization of myxoma leading to multiple strokes is an atypical clinical presentation. Our report would be a valuable addition to the already existing literature.

[Echocardiographic Diagnostics of Heart Tumors]

The article focuses on ultrasound diagnosis of cardiac tumors (CT). In recent time, the frequency of detecting cardiac neoplasm has been growing. Correct diagnosis at an early stage of the process would allow timely treatment. Before the introduction of two-dimensional echocardiography (EchoCG), life-time diagnosis of CT was very rare. This article describes major echocardiographic criteria for most common benign, malignant, and metastatic CTs. The article is illustrated with original echocardiographic images.

Unusual Presentation of Atrial Myxoma: A Case Report and Review of the Literature

BACKGROUND Although rare, atrial myxoma is the most common benign cardiac tumor. The recognized triad of presenting symptoms relates to constitutional, embolic, and obstructive effects produced by the tumor. However, the presentation may be non-specific and mimic other diseases, confounding diagnosis. CASE REPORT A middle-aged woman presented with wheezing and shortness of breath. With a strong background smoking history, the initial impression was that of acute bronchospasm. She however deteriorated rapidly, with decreased consciousness and cardiac arrest requiring resuscitation. Despite intensive care management, she died within 1 day of admission. Autopsy revealed a previously undiagnosed left atrial myxoma with coronary and systemic embolization. CONCLUSIONS This case highlights an unusual presentation of atrial myxoma, resulting in fatal simultaneous embolization to the coronary and cerebral arteries. This simultaneous embolic presentation is not common, but the potential consequences are serious. This report also demonstrates that the presentation of a left-sided atrial myxoma with cardiac asthma can mimic respiratory disease and confound diagnosis. In adult patients without a history of chronic respiratory disease, the possibility of cardiac asthma should always be entertained. Furthermore, the importance of considering atrial myxoma as a cause for cardiac asthma is emphasized. The use of transthoracic echocardiogram in aiding the rapid diagnosis of atrial myxoma is recommended. Finally, the continued acknowledgement of the important contribution the academic autopsy makes in complementing and improving clinical practice remains imperative.
