Background: Pulmonary vein (PV) reverse remodeling has been recognized following atrial fibrillation (AF) ablation. However, the extent of physiologic reverse remodeling after AF ablation and the potential impact of reverse remodeling on the radiographic diagnosis of PV stenosis have not been well characterized. Methods: From January 2004 to February 2014, 186 patients underwent paired cardiac magnetic resonance imaging (MRI) to delineate PV orifice dimensions before and after (mean 109 ± 61 days) an initial AF ablation...

INTRODUCTION: PVI is an effective, guideline-based treatment for drug refractory symptomatic AF. Balloon cryoablation has been shown to be a safe and effective method for PVI. In the STOP-AF trial, data was produced from practitioners performing PVI with significant experience at high volume centers. This study evaluates the effectiveness and safety of treating symptomatic, drug refractory AF with PVI via cryoablation after implementation in a regional medical center. METHOD: This represents a retrospective analysis of outcomes after cryoablation treatment for AF in 71 patients over 354...

Cor triatriatum sinister (CTS) is a rare congenital abnormality. Clinical presentation of patients with CTS mainly depends on the anatomic features of membrane and may vary from mild or moderate symptoms mimicking mitral stenosis to more severe and complicated cardioembolic stroke or a new onset heart failure. We herein have reported on a young male who presented with the signs and symptoms of mitral stenosis and was diagnosed as CTS with gradient on the orifice of the membrane after transthrocacic echocardiography...

In 2005, a 48-year-old man with a spinal cord injury had an inferior vena cava filter placed for recurrent deep vein thrombosis and pulmonary embolism. He was referred for filter retrieval after a computed tomography scan demonstrated caval stenosis and 2 fractured filter arms, 1 in a pulmonary artery and 1 penetrating into the retroperitoneum and impinging on the aorta. During retrieval, 1 arm was inadvertently advanced into the aorta, and embolization of the arm occurred to the left profunda femoris artery...

Circulatory arrest (CA) is traditionally utilized during the repair of total anomalous pulmonary venous return (TAPVR). Since 2005, we have exclusively repaired all types of TAPVR using continuous cardiopulmonary bypass. We present our technique using continuous cardiopulmonary bypass throughout the duration of the repair, by temporarily occluding the vertical vein and placing a pump sucker within the pulmonary venous confluence. This technique has been used on 29 consecutive patients and resulted in limited morbidity and absence of pulmonary vein stenosis from most recent follow-up...

BACKGROUND: Anomalous left brachiocephalic vein (ALBCV) is a rare and less known systemic venous anomaly. Infrequently, this vein takes an abnormal course and passes to the right behind or beneath the aortic arch to create the superior vena cava (SVC). Its incidence was reported much higher in patients with congenital heart disease (CHD) especially in conotruncal and aortic arch anomalies. It could be misdiagnosed with normal or abnormal mediastinal structures. It also could make complication during surgeries or invasive strategies...

BACKGROUND: -The frequency of pulmonary vein stenosis (PVS) after ablation for atrial fibrillation (AF) has decreased but it remains a highly morbid condition. While treatment strategies including PV dilation and stenting have been described, the long-term impacts of these interventions are unknown. We evaluated the presentation of severe PVS, and examined the risk for restenosis after intervention utilizing either balloon angioplasty (BA) alone or BA with stenting. METHODS: -This was a prospective, observational study of 124 patients with severe PVS evaluated between 2000 and 2014...

The model of acute pulmonary embolism in rabbits demonstrated reduced pulmonary blood flow, cardiac output, left atrial pressure, and blood flow in venae cavae against the background of elevated left pulmonary artery pressure and increased pulmonary vascular resistance. Simultaneously, the blood flow in the superior vena cava decreased to a lesser extent than that in the inferior vena cava, which was a characteristic feature of the model of pulmonary pathology. In contrast, when histamine was infused into the left jugular vein to equally elevate pressure in pulmonary artery as in the above model, the blood flow in the superior vena cava decreased to a greater extent than that in inferior vena cava...

The Melody® transcatheter pulmonary valve system was developed for placement within right ventricle-to-pulmonary artery conduits in patients with CHD for treatment of stenosis or regurgitation, providing an alternative to open-heart surgery. Abnormal systemic venous connections altering the catheter course to the right ventricle-to-pulmonary artery conduit may present a challenge to Melody® valve implantation. We present two such cases, in which the Melody® valve was successfully implanted in teenage patients with congenitally corrected transposition of the great arteries after Senning atrial switch operation...

Pulmonary hypertension is usually related to obstruction of pulmonary blood flow at the level of the pulmonary arteries (eg, pulmonary embolus), pulmonary arterioles (idiopathic pulmonary hypertension), pulmonary veins (pulmonary venoocclusive disease) or mitral valve (mitral stenosis and regurgitation). Pulmonary hypertension is also observed in heart failure due to left ventricle myocardial diseases regardless of the ejection fraction. Pulmonary hypertension is often regarded as a passive response to the obstruction to pulmonary flow...

We report cardiac arrest due to obstruction of the right ventricular outflow tract (RVOT) caused by an RVOT mass that was not identified preoperatively. A 62-year-old woman with renal cell carcinoma (RCC) experienced deteriorating hypotension and bradycardia during radical nephrectomy. Hemodynamic stability was maintained on extracorporeal membrane oxygenation, and after surgery, she was transferred to the intensive care unit. On postoperative day 3, transthoracic echocardiography showed an intracardiac mass obstructing the RVOT, which caused severe functional pulmonary stenosis and moderate resting pulmonary hypertension...

Radiofrequency catheter ablation has become a widely used intervention in the treatment of atrial fibrillation. Pulmonary vein stenosis (PVS) is one of the most serious complications associated with this procedure; the degree of stenosis ranges from mild (<50%) to complete venous occlusion. The natural history of PVS and the risk of progression of existing PVS are uncertain. Symptomatic and/or severe PVS is a serious medical problem and can be easily misdiagnosed since it is an uncommon and relatively new medical problem, often has low clinical suspicion among clinicians, and has a non-specific presentation that mimics other more common respiratory or cardiac diseases...

Atrial fibrillation is the most common heart rhythm disorder in United States, characterised by rapid and irregular beating of both the atria resulting in the similar ventricular response. While rate and rhythm control using pharmacological regimens remain the primary management strategies in these patients, radiofrequency catheter ablation (RFCA) is rapidly rising as an alternative modality of treatment. Increase in the incidence of RFCA has shed light on complications associated with this procedure. Pulmonary hypertension (PH) is one of the long-term complications that has been observed postcatheter ablation...

Among electrophysiologic procedures, catheter ablation of atrial fibrillation (AF) is challenging, requiring the isolation of all pulmonary veins (PVs). AF is associated with serious complications including PV stenosis. Presently described was a technically challenging case of PV isolation in a patient with left-sided pneumonectomy due to lung cancer.

BACKGROUND: Scimitar syndrome may be corrected using different techniques. Repair using an extracardiac conduit has rarely been performed. This study assessed the intermediate-term outcomes of this technique in adults. METHODS: From January 2000 to June 2011, 7 adult patients underwent correction with a ringed polytetrafluoroethylene conduit used to connect the scimitar vein (SV) to the left atrium, posterior to the inferior vena cava (IVC). Preoperative and perioperative data were reviewed retrospectively...
