We present the case of a 69-year-old patient who was referred to the Department of Echocardiography for surgical treatment of severe tricuspid valve regurgitation (TVR) with advanced congestive heart failure. In 2013 the patient underwent unsuccessful percutaneous ablation for permanent atrial fibrillation. In 2015, following numerous episodes of atrial fibrillation and congestive heart failure with left pleural effusion, the patient was admitted to another center. A transthoracic echocardiogram showed severe TVR and moderate precapillary pulmonary hypertension, confirmed at right cardiac catheterization...

OBJECTIVES: The incidence of both solitary pulmonary nodules (SPN) and non-valvular atrial fibrillation (NVAF) has increased over the past decade. We performed concomitant video-assisted thoracoscopic surgery with modified epicardial radiofrequency ablation procedure for NVAF and SPN resection. METHODS: Sixteen patients (7 men, mean age 62.6 ± 11.2 years) with SPN and NVAF underwent this procedure. Of these patients, 10 had paroxysmal atrial fibrillation and 6 persistent atrial fibrillation...

The pulmonary veins carry oxygenated blood from the lungs to the heart, but their importance to the radiologist extends far beyond this seemingly straightforward function. The anatomy of the pulmonary veins is variable among patients, with several noteworthy variant and anomalous patterns, including supernumerary pulmonary veins, a common ostium, anomalous pulmonary venous return, and levoatriocardinal veins. Differences in pulmonary vein anatomy and the presence of variant or anomalous anatomy can be of critical importance, especially for preoperative planning of pulmonary and cardiac surgery...

Hemoptysis may occur in patients with pulmonary venous obstruction and prominent decompressing vessels in the airways adjacent to the affected pulmonary veins. The options for treatment of hemoptysis are limited, particularly when efforts to alleviate pulmonary venous obstruction have failed. Here we describe a patient with hemoptysis associated with stenosis of the central left upper pulmonary vein and occlusion of the central left lower pulmonary vein. The left upper pulmonary vein was dilated with balloon catheters and a vascular plug was placed in the left lower pulmonary artery...

We present the rare case of a patient with pulmonary hypertension in the context of the stiff left atrial syndrome after extensive catheter ablation, a unique constellation characterized by high pulmonary artery and pulmonary artery wedge pressures due to left atrial dysfunction but normal left ventricular end-diastolic pressure, normal mitral valve, and absence pulmonary vein stenosis. This patient was surprisingly oligosymptomatic, however, which may have been due to a persistent post-puncture atrial septal defect, which may have allowed for controlled left atrial decompression, which is in line with the novel concept of the catheter-based creation of an intracardiac shunt as a treatment for heart failure...

The patient was a 63-year-old man with drug-resistant atrial fibrillation who developed coronary spasm during cryoballoon ablation (CBA). CBA was started from the left inferior pulmonary vein. ST elevations in II, III, and aVf, with reciprocal ST depressions in V2-5, occurred in association with chest pain just after balloon rewarming and deflation, and the patient's blood pressure fell to 50 mmHg. Coronary angiography revealed 90% diffuse stenosis from the orifice of segment 1 to segment 4 in the right coronary artery...

Two cats (2.5 months and 8 months old) were each evaluated due to a loud systolic murmur, and each was diagnosed with severe pulmonary artery stenosis at the bifurcation of the main pulmonary artery. Echocardiograms confirmed significant right atrial dilation and right ventricular dilation and/or hypertrophy that was progressive in one cat. Atenolol was initiated and the cats were referred for interventional therapy. Balloon angioplasty was performed via the jugular vein. In case 1, the pressure gradient across the stenosis was reduced from 169...

A 49-year-old male patient presented due to recurrent pain and swelling in the left leg. The patient had had deep venous thrombosis with pulmonary embolism 5 years previously. Since then, he had been treated with Vit-k-antagonists. Pronounced paraumbilical collateral circulation of unknown origin was striking. Doppler sonographic evaluation pointed to May-Thurner syndrome. This was confirmed by phlebography. Venous stenting of the stenosis in the left iliac vein achieved long-term symptom improvement. This case report is intended to draw attention to the rare May-Thurner syndrome as an important differential diagnosis of deep vein thrombosis and, at the same time, identify diagnostic and therapeutic treatment strategies...

Aims: Pulmonary vein stenosis or occlusion (PVS/O) following catheter ablation of atrial fibrillation is a rare but potentially severe complication. Treatment options include angioplasty with or without stent implantation, but data on outcome and optimal treatment strategy are limited. We report long-term results after catheter-based treatment of patients with symptomatic PVS/O. Methods and results: Retrospective analysis was performed in patients undergoing pulmonary vein (PV) angiography for suspected PVS/O...

OBJECTIVE: To investigate the clinical usefulness of echocardiography in the diagnosis of infracardiac total anomalous pulmonary venous connection (ITAPVC) in neonates and infants. METHODS: Retrospective analysis on 8 patients with ITAPVC was performed using echocardiography between April 2006 and December 2016. There were 4 boys and 4 girls with a mean age of 79.8 days (ranging from 15 to 195 days). A combined scanning via parasternal, subcostal and apical acoustic windows had been employed to diagnose ITAPVC and to trace the course and site of the anomalous pulmonary venous drainage, and to confirm the direction of the inter-atrial shunt and enlargement of right atrium and right ventricle...

Regulation of blood flow to the right ventricle differs significantly from that to the left ventricle. The right ventricle develops a lower systolic pressure than the left ventricle, resulting in reduced extravascular compressive forces and myocardial oxygen demand. Right ventricular perfusion has eight major characteristics that distinguish it from left ventricular perfusion: (1) appreciable perfusion throughout the entire cardiac cycle; (2) reduced myocardial oxygen uptake, blood flow, and oxygen extraction; (3) an oxygen extraction reserve that can be recruited to at least partially offset a reduction in coronary blood flow; (4) less effective pressure-flow autoregulation; (5) the ability to downregulate its metabolic demand during coronary hypoperfusion and thereby maintain contractile function and energy stores; (6) a transmurally uniform reduction in myocardial perfusion in the presence of a hemodynamically significant epicardial coronary stenosis; (7) extensive collateral connections from the left coronary circulation; and (8) possible retrograde perfusion from the right ventricular cavity through the Thebesian veins...

Introduction Although the right jugular vein approach for percutaneous pulmonary valve implantation is well described, there are no reports that describe a percutaneous pulmonary valve implantation through a left superior caval vein to coronary sinus pathway. Case A 14-year-old female with tetralogy of Fallot, mesocardia, left superior caval vein draining into the coronary sinus, and hemiazygos continuation of the inferior caval vein underwent ventricular septal defect closure, with homograft insertion from the right ventricle to the pulmonary artery, patch augmentation of the left pulmonary artery, and creation of an atrial communication...

Bland-White-Garland (BWG) syndrome (anomalous origin of the left coronary artery from the pulmonary artery) is a rare disease which may result in myocardial infarction, congestive heart failure or sometimes death during the early infantile period. We present a 57-year-old female with BWG syndrome. At the age of 20, she was diagnosed with BWG syndrome and underwent coronary artery bypass grafting of a saphenous vein to the proximal portion of the anterior descending branch of the left coronary artery and ligation of the anomalous artery...

Radiofrequency ablation procedures for atrial fibrillation are occasionally associated with pulmonary vein stenosis (PVS). A common treatment for PVS is catheter intervention; however, because of the high restenosis rate, it is not suitable for young patients. The case presented herein is of a young male patient with severe bilateral PVS who underwent successful surgical pulmonary vein repair by sutureless technique. The stenotic lesions of the pulmonary veins were dissected and were covered using autologous pericardium...
