Cerebral Embolic Protection During Transseptal Biopsy of Left Atrial Mass.

Diagnostic biopsy of a left atrial mass is technically feasible but has the risk of tumor embolization causing stroke or seeding. In this case report, we highlight the technical steps for left atrial mass biopsy under transesophageal echocardiography guidance by using cerebral embolic protection. Pathologic examination disclosed low-grade B-cell lymphoma.

Electrocardiograms Recorded After Asystolic Cardiac Arrest.

A man with a history of drug abuse was found down at home and was asystolic. Following restoration of sinus rhythm, a hypothermia protocol brought his temperature to 32.5°C (90.

Type I Second Degree Atrioventricular Block in a Woman With Remote Repair of a Ventricular Septal Defect.

In a 45-year-old woman with syncope, an electrocardiogram revealed intermittent asymptomatic type I second degree atrioventricular block, right bundle branch block and left anterior fascicular block. An echocardiogram documented concentric left ventricular hypertrophy and right ventricular dilatation and hypokinesia. Because the patient did not have second degree atrioventricular block at the time of an electrophysiological study, the atrioventricular node, the left posterior fascicle, and the His bundle all remain potential sites for the type I second degree atrioventricular block on her initial electrocardiogram.
