introduction pulmonary vein stenosis includes narrowing of one or more pulmonary veins that may have congenital or acquired causes. congenital pulmonary vein stenosis is a rare condition and also a rare cause for pulmonary hypertension. since identifying the etiology of pulmonary hypertension plays a crucial role in medical and surgical planning, we decided to introduce a rare case of pulmonary...
introduction pulmonary vein (pv) isolation is considered as a key to atrial fibrillation (af) treatment. cryoballoon ablation is an effective therapy for pv isolation for af with minimal side effects and was approved by the us food and drug administration (fda) several years ago. successful isolation of pvs during cryoablation depends on the balloon temperature and helps in early identification...
the use of diagnostic and therapeutic methods for assessing pulmonary vein due to its status as a main source of ectopic beats for the initiation of atrial dysrrythmias is strongly recommended. we report the case of a 13-year-old girl who was admitted to our hospital with the electrocardiogram manifestation of an ectopic atrial tachycardia. the focus of arrhythmia was inside the right upper p...
Deep Vein Thrombosis, Pulmonary Embolism and Related Factors in Patients with Traumatic Brain Injury
Background and Objective:Deep vein thrombosis and pulmonary embolism are fatal problems following brain trauma that, if left untreated, can dramatically increase mortality. Therefore, the present study aimed to evaluate deep vein thrombosis, pulmonary embolism and related factors in patients with traumatic brain injury. Materials and Methods:This cross-sectional study was performed on 38 patie...
Çor triatriatum is a cardiac anomaly that is due to failure of resorption of the common pulmonary vein results in a left atrium divided by an abnormal fibromascular diaphragm into posterosuperior and the anteroinferior chambers. The communication between the divided atrial chambers may be large, small or absent, depending on the size of the opening (s) in the diaphragm, which determines the d...
the main goal of this report was to share with clinicians an atypical presentation of pulmonary thromboembolism (pte) in a young male`s post-appendectomy, whom he had no significant predisposing factors for such disease. the case also introduced for re-examining the challenges of pte clinical manifestations which may mimic other differential diagnosis. pte is an abrupt blockage of the pulmonary...
Pulmonary thromboembolism (PTE) is a clinically critical disease, misdiagnosis or delayed diagnosis of which can lead to increased rate of mortality. For prevention of recurrence of PTE, recognition of its risk factors or underlying diseases is of great importance. PTE is common in patients with cancer and has high morbidity and mortality rates. Although cancer is a lethal condition, PTE accele...
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...
total anomalous pulmonary venous connection (tapvc) is an anomaly in which the pulmonary veins are directly connected to one of the systemic veins or drain into the right atrium. management of pulmonary hypertension after the total correction of this congenital cardiac anomaly is very important. unligation of the vertical vein in the supracardiac type of this anomaly can be a draining pathway f...
INTRODUCTION Accurate discrimination of atrial and pulmonary vein potentials recorded circumferentially within the pulmonary veins is important when performing segmental isolation of the pulmonary veins in patients with atrial fibrillation. METHODS AND RESULTS Twenty patients with paroxysmal atrial fibrillation underwent pulmonary vein mapping with a decapolar Lasso catheter during sinus rhyt...
