Left atrial myxomas are rare primary cardiac tumors. Their incidence is estimated to be about 0.1% of total cases. Neurological complications resulting from cardiac myxomas are seen in 20–35% of patients. Transesophageal echocardiogram (TEE) is preferred over transthoracic echocardiogram for evaluation of left atrial myxoma. Three-dimensional (3D) echocardiography ensures better visualization of intracardiac structures. It has been used prior to surgery for diagnostic support in the surgical treatment of cardiac masses. We present a case of a 46-year-old Hispanic male who developed acute ischemic stroke of left frontal lobe and was also found to have multiple ‘silent’ cerebral infarcts in the MRI of the brain. On further workup, he was found to have a left atrial myxoma on 3D TEE. This was resected with the assistance of intra-operative 3D TEE imaging. We present this case to increase awareness and to stress at early evaluation of secondary causes of ischemic cerebrovascular accident, outside the realm of hypercoagulability. This case also exhibits the need for basic cardiac workup in young individuals who present with symptoms of intermittent palpitations or chest pain to minimize significant morbidity or mortality.
We report the case of a 45-year-old female referred to us with progressive shortness of breath and a huge left mediastinal mass. Computed tomography of the chest revealed a mass occupying the posterior mediastinum and extending from the apex caudally to the left hemidiaphragm. Further magnetic resonance imaging demonstrated tumor extension to the left interverteberal foramina of T5-T6 and T6-T7. Excision of the mass was performed through a left posterolateral thoracotomy. Histology confirmed a mediastinal ganglioneuroma. This is an unusual tumor with more than one extension in the spine. Ganglioneuromas are rare tumors of the peripheral nervous system. Most of these tumors are, however, retroperitoneal and are more common in children and young adults. Ganglioneuromas arise from neural crest cells. These tumors are mostly asymptomatic, but some may present with hypertension and flushing. Massive tumors can present with pressure symptoms.
Retroperitoneal hemorrhage from iliac artery injury is a potentially serious complication of vascular interventional procedures leading to hemorrhagic shock and death if not diagnosed early and treated promptly. We report a 70-year-old male admitted to our facility with non-ST-elevation myocardial infarction, whose heart catheterization revealed left anterior descending artery (LAD) with 80% proximal, 95% mid and 100% distal disease. The left circumflex and right coronary arteries were 100% occluded proximally and received collaterals from the LAD. The patient declined coronary artery bypass surgery; therefore, the decision was made to perform high-risk percutaneous coronary intervention (PCI) of the LAD with Impella left ventricular assist device support. Left femoral artery angiogram revealed severely tortuous and calcified aorta, left external iliac and left common iliac arteries, and was accessed with 14-inch Impella sheath. He developed groin pain with mild hypotension thought to be due to sedation, which responded to intravenous fluids and dopamine. He underwent successful rotational atherectomy of the proximal and mid LAD with deployment of drug-eluting stents. Following PCI, he suffered acute profound hypotension necessitating intravenous fluids and vasopressor support with epinephrine. Emergency transthoracic echocardiogram did not reveal any pericardial effusion, and showed normal left ventricle and right ventricle systolic function. The Impella device was removed and selective left common iliac angiogram from the right femoral access revealed a vascular injury site with shift of the bladder to the right indicative of retroperitoneal hematoma. A digital subtraction angiogram revealed extravasation of blood at the vascular injury site. An 8.0 × 59 mm iCAST covered stent was deployed to the left external iliac artery with successful sealing of the perforation. The Impella device site was closed with two Perclose devices. The patient required 4 units of packed red blood cell transfusion. His hospital course was complicated by transient acute kidney injury, with return of his renal function to baseline at discharge 10 days later. This case underscores the importance of prompt recognition and treatment of vascular complications associated with interventional procedures, and highlights some of the risk predictors of such complications, which should be anticipated and planned for prior to intervention.
A 72-year-old male is diagnosed with paradoxical embolus after he presented with concurrent deep vein thrombosis, stroke, and multiple arterial emboli in the presence of a patent foramen ovale (PFO). Paradoxical embolus requires the passage of a thrombus from the venous into the arterial circulation through a right-to-left shunt leading to systemic embolism. But, despite the high incidence of PFO (27.3% across all age groups by autopsy), paradoxical embolism (PDE) is uncommon, representing <2% of all arterial emboli. We present a case report where a thrombus has been directly observed passing through the PFO during an echocardiogram study; thus, clearly delineating the true cause of multiple thromboemboli and stoke in our patient. Subsequent Transesophageal Echocardiography (TEE) also interestingly showed the thrombus in transit in the aorta and pulmonary artery.
Coronary artery disease is a major cause of morbidity and mortality, and while most commonly is atherosclerotic, it can present with variable manifestations, both congenital and acquired. One such manifestation is coronary aneurysm, which is a localized dilatation of a coronary artery wall segment to greater than 1.5 times the adjacent normal segments. While a dilated outpouching of a coronary artery has been commonly classified as a coronary aneurysm, a non-dilated outpouching is rare and is referred to as a diverticulum, with only one previous case report in the literature. It is conceivable that other cases of coronary artery diverticulum may have been previously reported as an aneurysm, given the overlapping angiographic appearance. We present a case of a 72-year-old female patient with an incidental finding of left main coronary artery diverticulum on diagnostic coronary angiogram done for preoperative liver transplantation evaluation.
