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...

BACKGROUND: The second-generation cryoballoon has been recently introduced into clinical use for pulmonary vein isolation (PVI). Data on the feasibility, long-term outcome, and optimal freeze cycle are still limited. We assessed the 1-year clinical outcome after second-generation CB ablation with single 3-minute freeze techniques, and clinical variables associated with AF recurrence. METHODS: One hundred eight paroxysmal atrial fibrillation (PAF) patients undergoing cryothermal PVI were enrolled...

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...

BACKGROUND: An anomalous origin of the right coronary artery is rarely observed, with a reported incidence between 0.026% and 0.25%. This condition is often completely asymptomatic and is found incidentally during angiographic evaluation for other cardiac diseases. However some patients present with exertion angina or sudden death. Surgical treatment in patients with anomalous RCA is still controversial. Treatment can be conservative, angioplasty or surgery. CASE PRESENTATION: A 59-year-old man was admitted with severe mitral stenosis...

BACKGROUND: Haemoptysis is a common clinical symptom with a complicated aetiology. Patients usually visit pulmonologists initially and are misdiagnosed due to physician ignorance regarding the rare causes of haemoptysis. METHODS: We report three cases of haemoptysis due to pulmonary vein stenosis accompanied by catheter ablation for atrial fibrillation and review the related literature. RESULTS: The three patients presented haemoptysis and they all had the history of catheter ablation...

End stapler is one of the indispensable devices for pulmonary resections. Various surgical staplers are now available and appropriate types are selected to dissect pulmonary parenchyma, vessel, or bronchus. In this study, we retrospectively reviewed the patients who received pulmonary wedge resections using newly released curved stapler (Endo GIA Radial Reload with Tri-Staple technology). Between April 2013 and October 2014, 10 lesions from the 9 patients were resected using the curved staplers. The reasons for the application of the staplers were pleuro-pulmonary adhesion in 3 lesions and centrally location in 7 lesions...

OBJECTIVES: This study sought to determine the feasibility and safety of unzipping small-diameter stents (SDS) in a growing animal model. BACKGROUND: SDS implanted to relieve stenosis of blood vessels in infants may result in refractory stenosis as the child grows. If stents can be longitudinally fractured-unzipped-then the target vessel can potentially be redilated to the eventual adult vessel diameter. METHODS: Fifty stents (diameter 4 to 7 mm) were implanted in 5 neonatal piglets (mean age and weight = 1...

Pulmonary vein stenosis (PVS) is an uncommon but devastating complication of atrial fibrillation (AF) ablation. Patients are often misdiagnosed due to non-specific symptoms and the challenges of visualising the pulmonary veins on standard chest imaging. Delays in treatment result in worsening symptoms and pulmonary venous occlusion. The optimal method of intervening for PVS has not been well established. Restenosis after successful intervention is common, warrants active surveillance, and is the focus of research into prevention and management strategies...

Changes in cardiac tissue properties following the application of various ablation modalities may lead to the development of an array of associated complications. The application of either radio frequency (RF) or cryothermal ablations will alter the biomechanical properties of various cardiac tissues in a differential manner; in some cases, this may be attributable to increased incidences of cardiac tamponade, pulmonary vein stenosis, and/or atrial-esophageal fistula. Thus, a greater understanding of the underlying changes in tissue properties induced by ablative therapies will ultimately promote safer and more efficacious procedures...

Pulmonary vein stenosis (PVS) is an uncommon but serious complication following radiofrequency ablation for atrial fibrillation. Occurrence of this complication has risen with increased rates of ablation procedures, with >50,000 AF ablation procedures performed per year, and can occur within weeks to months post procedure. Currently, the main therapies for PVS include percutaneous interventions with balloon angioplasty and stenting, but these treatments are complicated by a high rate of restenosis. The optimal treatment for recurrent pulmonary vein in-stent restenosis has not been determined...
