objective(s): several researchers have reported the relationship between infertility in male and varicocele for so many years but the implication of varicocele in female patients is remains elusive. here, we aim to examine the effects of unilateral varicose ovarian vein on antioxidant capacity and oocyte quality of rat ovary after the experimental creation of varicocele in female rats. material...

• For almost as long as the problem of venous return has been studied, two different factors have been claimed to be important in determining venous return to the heart." These are: (1) the force of the systemic arterial pressure pushing blood through the systemic circulation toward the heart, and (2) factors on the venous side of the heart that affect venous return, including rhythmic suction ...

Atrial fibrillation is commonly seen in atrial dilation and fibrosis of the atrium. As cancer patients live longer, cardiac metastasis is an increasingly common finding in this population, occurring in up to 14% of cancer patients. This problem holds significance in relation to operability and type of treatment. Cardiac invasion through the pulmonary veins is a rare occurrence, as is sarcomatoi...

Chylopericardium is a rare complication of cardiac surgery. It may be caused by a lesion in the thoracic duct or its tributaries or by thrombosis in the confluence of the jugular and left subclavian veins, obstructing the drainage of the thoracic duct. The treatment may be conservative or surgical, depending on the duration and on the volume of the effusion. We report the case of a 24-year-old ...

Background Three-dimensional, whole-heart, navigator-gated, contrast-enhanced MRI techniques are used to acquire cMRVs which can be used for planning lead placement in cardiac resynchronization therapy (CRT). In order to reduce cardiac motion artifacts, it is desirable to set the trigger delay time to acquire image data only during periods of low vessel motion, typically assumed to be during di...

THE organism exposed to gravitational or accelerative stress would find it advantageous if active venous constriction occurred in the dependent portions of the body. Since the veins contain 60-75 per cent of the total systemic blood volume, a relatively small per cent decrease in capacity of the venous reservoir could yield a considerable increase in the volume of the diastolic cardiac inflow a...

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...

background: in many clinical situations, knowledge of central venous pressure (cvp) is important.  measurement of cvp is not always possible.   objective: to determine if intraocular pressure (iop) can be used as an estimate for cvp.   methods: iop and cvp were measured concurrently in 30 candidates of coronary artery bypass graft surgery.  those with carotid artery or jugular venous diseases a...
