The Mean

We report the case of a 41-year-old female patient with symptoms of cerebrovascular accident manifesting with loss of consciousness during episodes of cough. Computed multislice chest tomography showed a 7.3- by 4.15-cm mass in the left atrium. A transesophageal echocardiogram showed a giant mass in the left atrium that passed through the mitral valve to the left ventricle, and severe obstructive stenosis was suggested by the mean transmitral gradient. After a comprehensive assessment of the mass, we decided to perform surgery. The pedunculated and fragile mass was attached to the interatrial septum with its handle, and the majority of it prolapsed through the mitral valve to the left ventricle and became stacked among the mitral valve leaflets. The removed mass was analyzed histopathologically and was found to be a myxoma. It is important for the cardiac surgeon to surgically remove an atrial myxoma because of the risks associated with embolization, including sudden death, as myxoma can block the blood supply from the atrium to the ventricle.

A 37-year-old woman with a past medical history significant for congenital deafness and surgically repaired Tetralogy ofFallot presented with three day history of nausea, vomiting, fever, chills, dyspnea, and lower extremity weakness and physicalexamination notable for Janeway lesions. Peripheral blood and urine cultures were positive for methicillin sensitive Staphlococcusaureus. Transesophageal echocardiogram was consistent with mitral valve endocarditis. Computed tomography images of thechest, abdomen and pelvis demonstrated septic emboli to multiple organs including lungs, liver, spleen and kidneys. Salinecontrast study was negative for a patent foramen ovale, or residual ventricular septal defect. Thus, effectively ruling out left toright intracardiac shunt as the cause of pulmonary septic emboli from mitral valve endocarditis. Moreover, cardiac MRI did notshow any evidence of right sided endocarditis. Therefore, we believe the source of septic pulmonary emboli from mitral valveendocarditis to be through the bronchial arteries. The extent of septic emboli to various organs and the precise mechanism ofpulmonary emboli from left sided endocarditis in a patient with surgically altered cardiac anatomy make this case unique.

Introduction: We sought to clarify the electrocardiographic and electrophysiological characteristics of ventricular arrhythmias (VAs), including idiopathic ventricular tachycardia (VT) and premature ventricular contractions (PVCs), with acute successful radiofrequency catheter ablation (RFCA) at the left ventricle basal inferoseptum near the mitral annulus (LV-BIS-MA). Methods and Results: Twenty-five patients with acute successful RFCA at the LV-BIS-MA were included in this study. The S wave amplitudes on lead III during VAs were 1.54 ± 0.38 mV, significantly larger than that on lead II (0.55 ± 0.19 mV) and aVF (1.04 ± 0.31 mV) (P < 0.01). The RFCA start-to-effect time was 10.2 ± 5.8 seconds (s) in 21 patients (84.0%). In the remaining 4 patients (16.0%), the mean duration of successful RFCA was not well determined due to infrequent nature of clinical VAs during ablation. Trans-septal approach were utilized in all the 25 cases. Intra-cardiac echocardiography (ICE) showed that the ablation catheter tip was underneath the anterior leaflet of the mitral valve via the reversed C‐curve technique. Early (within 3 days) and late (one-year) recurrence rates were 4.0% (one patient) and 12.0% (three patients), respectively. No complications occurred during RFCA or the one-year follow up. CONCLUSION: LV-BIS-MA VAs are a subgroup of idiopathic VAs with distinctive ECG and EP features. RFCA via a transseptal approach using a reversed C curve technique is effective for better identification and targeting the areas of VAs origin and ICE showed that the ablation catheter tip was underneath the anterior leaflet of the mitral valve.
