Poor left ventricular growth and diastolic dysfunction long after simple total anomalous pulmonary venous connection (TAPVC) repair has been well documented and is believed to originate from insufficient pre-operative volume preload. The objective of the study was to confirm these findings.
Venous leg ulcers are open lesions between the knee and the ankle joint, which occur in the presence of venous insufficiency. There are theories to explain the causes of venous insufficiency, which ultimately leads to venous hypertension and can result in leg ulceration. Although many patients present with evidence of venous hypertension, others do not, except for the manifestation of the ulcer. There are risk factors associated with venous insufficiency and a holistic approach must be taken in order to inf...
The real mechanism for the development of the later stages of chronic venous insufficiency still remains unclear. Venous hypervolemia and microvascular ischemia have been reported to be the consequences of venous insufficiency. The aim of this study was to investigate the effects of induced venous hypovolemia by dorsiflexion exercise in patients with venous leg ulcers.
Venous disease is more common than peripheral arterial disease. Pathophysiologically, venous disease can be associated with obstruction, reflux, or both. A common feature in chronic venous disease is ambulatory venous hypertension. Inflammatory and pro-thrombotic mechanisms can be activated. The current therapies, including compression, ablation, and recanalization are discussed.
The growth in the experimental research of facilities to support extracorporeal circulation requires the further development of models of acute heart failure that can be well controlled and reproduced. Two types of acute heart failure were examined in domestic pigs (Sus scrofa domestica): a hypoxic model (n = 5) with continuous perfusion of the left coronary artery by hypoxic deoxygenated blood and ischemic model (n = 9) with proximal closure of the left coronary artery and controlled hypoperfusion behind t...
May-Thurner Syndrome (MTS) is a condition in which the left common iliac vein is compressed by the right common iliac artery, which may cause swelling, pain or deep venous thrombosis of the left lower extremity.Post-thrombotic syndrome, non-thrombotic chronic venous insufficiency and recurrence after venous thrombosis are also possible complications. Although MTS combined with left iliac arteriovenous fistula (AVF) is rarely reported, we treated three such cases in the past year.
Use and Outcomes of Subcutaneous Implantable Cardioverter Defibrillator (ICD) After Trans-venous ICD Extraction: an Analysis of Current Clinical Practice and a Comparison with Trans-venous ICD Reimplantation.
The subcutaneous implantable cardioverter-defibrillator (S-ICD) does not require the insertion of any leads into the cardiovascular system.
Severe aortic stenosis frequently involves the development of left ventricular hypertrophy (LVH) creating a dichotomous hemodynamic state within the coronary circulation. Whilst the increased force of ventricular contraction enhances its resultant relaxation and thus increases the distal diastolic coronary 'suction' force, the presence of LVH has a potentially opposing effect on ventricular-coronary interplay. The aim of this study was to use non-invasive coronary wave-intensity analysis (WIA) to separate a...
Venous revascularization is an approach used in patients with total venous occlusion requiring venous access for cardiac device lead placement. Several percutaneous approaches to venous revascularization have been proposed. For the first time, we describe the case of a 69-year-old male with total venous occlusion who was successfully revascularized using a 'diathermy' technique.
Radiofrequency (RF) ablation of idiopathic ventricular arrhythmias (IVA) from coronary venous system (CVS) has been increasingly performed but, real effect of ablation lesions from CVS on epicardial myocardium has not been studied.
Patients with left ventricular hypertrophy (LVH) have reportedly higher than normal mortality and incidences of cardiovascular events. Coronary microvascular pathophysiology also appears to differ from other populations. Such coronary microcirculation dysfunctions are considered strong causes of cardiac events.
The postoperative left ventricular end-systolic volume index and ejection fraction are benchmarks of surgical ventricular reconstruction but remain unpredictable. This study aimed to identify who could be associated with a higher long-term survival by adding surgical ventricular reconstruction to coronary artery bypass grafting than coronary artery bypass grafting alone (responders to surgical ventricular reconstruction).
Venous flaps from the distal volar forearm are said to be suitable flaps for finger reconstruction. The pliability of the forearm venous flap makes it easy to follow the curvature of the finger contour. The thickness of the flap makes it appropriate as a flap for finger resurfacing. Following the venous network at the palmar forearm, diverse patterns of the venous flaps can be designed. This article describes the use of a 2-concatenated paddle, flow-through arterialized venous flap design for simultaneous r...
Developmental venous anomaly (DVA) or venous angioma is a common anomalyof cerebral veins that is found incidentally in the majority of cases.There are few cases of arteriovenous shunting in DVA associated with a more malignant course of the disease. Whether these DVAs with shunts are of congenital pathology or lifetime formations is unclear.
To evaluate the performance of a closed-cell designed venous stent for the treatment of chronic ilio-femoral venous outflow obstruction (VOO) in the shortterm.
Coronary-cameral fistula (CCF) is a rare connection between a coronary artery and a chamber of the heart. It most often derives from the right coronary artery and drains into the right ventricle. CCF originating from all 3 major coronary vessels and draining into the left heart is an extremely rare coronary artery malformation. A 47-yearold-man who was admitted to the clinic with angina pectoris and positive cardiac markers suddenly developed ventricular fibrillation (VF) while being prepared for coronary c...
Venous sampling is the gold standard for localizing abnormal hormone secretion in several endocrine disorders. The most common indication for venous sampling is in the workup of primary aldosteronism, adrenocorticotropic hormone-dependent Cushing's syndrome, and hyperparathyroidism. In experienced hands, venous sampling is safe and accurate. This review discusses the role of venous sampling in the workup of endocrine disease, describing the underlying anatomy and pathophysiology, as an understanding of thes...
A 15-month-old male was referred for biopsy of presumed rhabdomyosarcoma in the setting of rapidly progressing left-sided proptosis. Examination revealed left periorbital edema and left hypoglobus. MRI revealed a soft-tissue density mass within the left lateral retrobulbar space. Several days later, he developed acute periorbital ecchymosis and increasing edema. With high suspicion for a vascular lesion, a CT scan was performed with dynamic arterial and venous imaging. Central filling was noted in the later...
Isolated persistent left superior vena cava (SVC) in the absence of right SVC is a rare congenital variant of thoracic venous drainage with the left subclavian and jugular veins that drain into the right atrium through the coronary sinus. Inferior vena cava interruption with azygos continuation is another congenital anomaly resulting in venous drainage of the lower extremities via a typically dilated azygos vein. Although both variants are generally asymptomatic and incidentally detected, these can have cli...
Here, we report on the case of a 4-year-old child with large atrial septal defect (ASD) and severe pulmonary hypertension presenting an ischemic cardiomyopathy secondary to left main (LM) compression by a dilated pulmonary artery trunk. Despite of surgical treatment consisting in ASD closure and coronary artery bypass grafting, the patient was not weanable from ECMO. Control coronarography showed a near-occlusion of the left mammary bypass. A rescue percutaneous LM angioplasty with drug-eluting stent implan...
An eight-year-old girl presenting with fulminant myocarditis and cardiogenic shock was placed on peripheral extracorporeal membrane oxygenation (ECMO). Patient was switched to central ECMO due to inadequate venous drainage and echocardiogram showed left ventricular (LV) thrombus. She underwent removal of LV thrombus with LV venting. Echocardiogram showed LV thrombus again two day later. The LV thrombus was again removed and biventricular ventricular assist device was initiated to avoid further thrombus form...
Optimal prophylactic strategies in pregnant women with a history of venous thromboembolism (VTE) are unknown.
Venous thromboembolism is a common complication of cancer, but the risk of developing venous thromboembolism varies greatly among individuals and depends on numerous factors, including type of cancer. We aimed to develop and externally validate a clinical prediction model for cancer-associated venous thromboembolism.
A 62-year-old man was referred to our institution for high-density, symptomatic PVCs with resultant decrease in LV function having failed prior ablation attempts. Successful, durable ablation of the patient's mid-myocardial PVC arising from the LV summit region was achieved through the proximal great cardiac vein with ablation depth augmented by use of half-normal saline irrigant. Though standard ablation of ventricular arrhythmias using normal saline irrigation from the coronary venous system has been well...
