Acute COVID-19 Pneumonia Unmasking a Large Left Atrial Myxoma.

This is a case of acute coronavirus disease 2019 pneumonia that revealed an incidental large atrial myxoma with obstructive physiology that ultimately required emergent treatment with a definitive atriotomy and resection of the underlying myxoma.

Postcorrective surgery improvement of nocturnal hypoxemia in a case of partial anomalous pulmonary venous connection and aberrant hepatic vein drainage.

Partial anomalous pulmonary venous connection (PAPVC) is a rare congenital anomaly that leads to an anatomical left-to-right shunt. Termination of the intrahepatic inferior vena cava (IVC) with its azygos continuation associated with the hepatic venous connection to the left atrium (LA) is also a rare congenital anomaly that results in an anatomical right-to-left shunt. A 65-year-old male presented with severe dyspnea on exertion and pedal edema. He was further diagnosed at our clinic and was found to have both the aforementioned congenital abnormalities, creating a bidirectional shunt. On further investigation, he was found to have nocturnal hypoxemia on overnight oximetry. The patient was successfully treated via surgical corrections of the congenital anomalies leading to symptomatic improvement as well as the resolution of nocturnal hypoxemia.

Metastatic meningioma extending into the left atrium through the pulmonary vein.

Left atrial extension of pulmonary tumors through the pulmonary vein is most often associated with primary malignancies and is rarely associated with metastatic disease. We present the first, to our knowledge, reported case of a patient with a history of intracranial meningioma resections presenting with metastatic meningioma to the right lower lobe with extension into the left atrium through the pulmonary vein.

Anomalous coronary circulation: left anterior descending and left circumflex coronary arteries arising from the right sinus of valsalva.

Approximately 1% of adults who undergo cardiac catheterization have coronary anomalies. Patients may present with chest pain, arrhythmias, presyncope, and sometimes sudden cardiac death. Multidetector computed tomography (MDCT) is an excellent tool for identifying coronary artery anomalies and defining their course and relationship to the great vessels and surrounding structures; its value is incremental to conventional angiography. We present a rare case of a coronary anomaly involving three separate ostia at the right sinus of Valsalva for the left and right coronary vessels.
