Primary Pulmonary Vein Leiomyosarcoma: A Case Report
Primary leiomyosarcoma of the heart is extremely rare and found in about 0.2% of all cardiac tumors. Here in a 26-year-old man with progressive dyspnea, which had started since 2 months ago, is presented. Echocardiography revealed a left atrial mass, which was suggestive for a atrial myxoma.On the surgery, a tumoral tissue in the left atrium and pulmonary veins with attachment to peripheral sof...
متن کاملTrastuzumab increases pulmonary vein arrhythmogenesis through modulating pulmonary vein electrical and conduction properties via phosphatidylinositol 3-kinase signaling
Objective(s): Drug-induced atrial fibrillation (AF) is considered an adverse effect of chemotherapeutic drugs. AF is a crucial risk factor for stroke, heart failure, myocardial infarction, and mortality. Pulmonary veins (PVs) are considered triggers inducing AF, and the sinoatrial node (SAN) may modulate PV activity and participate in AF genesis. AF was associated with...
متن کاملLeft atrial-pulmonary vein reentrant tachycardia following pulmonary vein isolation.
Pulmonary vein isolation has become the cornerstone of ablation for atrial fibrillation. However, it is sometimes followed by the development of left atrial macro-reentrant tachycardia. There is evidence to suggest that the myocardial sleeves within the pulmonary veins may be implicated in the mechanism of the tachycardia. Here we present a case of a post-ablation macro-reentrant tachycardia, i...
متن کاملSpontaneous and induced pulmonary vein tachycardia after pulmonary vein isolation.
A case is reported of recurrence of paroxysmal atrial fibrillation after pulmonary vein ablation. A second procedure achieved isolation of three pulmonary veins and showed persistence of pulmonary vein tachycardia in one with implications concerning the electrophysiology of atrial fibrillation.
متن کاملPulmonary vein thrombosis.
Pulmonary vein thrombosis is difficult to diagnose clinically and requires a combination of conventional diagnostic modalities. Transesophageal echocardiography was used in the present case to readily diagnose this entity and follow thrombus regression on anticoagulant therapy. This limited experience suggests that transesophageal echocardiography may be the initial diagnostic study of choice f...
