Varun Aggarwal, Michaki Imamura, Carlos Acuna, Antonio G Cabrera
In this study, we report a patient with pulmonary atresia with intact ventricular septum (PA/IVS), confluent pulmonary arteries supplied by an arterial duct, and chromosome 22q11.2 microdeletion. The 22q11.2 deletion syndrome has been associated with anomalies of the outflow tracts, such as tetralogy of Fallot with either pulmonary stenosis or atresia, but we are aware of a solitary case described with pulmonary atresia when the ventricular septum is intact. The presence of genetic malformations can have long-term co-morbidities...

Patent ductus arteriosus (PDA) stenting has gained acceptance for palliation in cyanotic congenital heart disease. The PDA in tetralogy of Fallot with pulmonary atresia (ToF-PA) arises, in the left aortic arch, from underneath the arch and connects to the proximal left pulmonary artery, often resulting in stenosis. The PDA is usually elongated and tortuous, making stent implantation challenging. Shorter duration of palliation, aggravation of branch pulmonary artery stenosis resulting in poor growth and difficulty at surgery makes ductal stenting controversial...

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...

Takayasu Arteritis (TA) is an inflammatory disorder involving the thoracoabdominal aorta and its branches and the pulmonary arteries, with eventual vascular stenosis, occlusion, or aneurysm formation. Conventional angiography has been the reference imaging standard for diagnosis of TA. The purpose of this case report is to demonstrate the utility of MR imaging and MR angiography in the diagnosis of Takayasu Arteritis in a pediatric patient. The patient is a 15-year-old female patient presenting with anemia, hypertension, and acute kidney injury...

Children requiring reimplantation of a branch pulmonary artery (PA) are at risk for postoperative stenosis and impaired growth of the reimplanted PA. Outcomes and risk factors for reintervention and impaired growth are incompletely described. We reviewed data on patients who underwent reimplantation of a branch PA between 1/1/99 and 5/1/15 at a single center. The primary outcome was reintervention to treat postoperative stenosis. The secondary outcome was "catch-up" growth (faster diameter growth of the affected PA compared with the unaffected PA from the preoperative to follow-up measurements...

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...

Brian A Scansen
Coronary artery anomalies represent a disease spectrum from incidental to life-threatening. Anomalies of coronary artery origin and course are well-recognized in human medicine, but have received limited attention in veterinary medicine. Coronary artery anomalies are best described in the dog, hamster, and cow though reports also exist in the horse and pig. The most well-known anomaly in veterinary medicine is anomalous coronary artery origin with a prepulmonary course in dogs, which limits treatment of pulmonary valve stenosis...

To explore the accuracy of main pulmonary artery (MPA) and ascending aorta (AAO) image evaluation in pediatric patients with single ventricle (SV) by comparing dual-source computed tomography (DSCT) with echocardiography. Thirty-one children with SV were retrospectively enrolled. The stenosis, dilation, and location of MPA and AAO were independently evaluated by DSCT and echocardiography. The accompanying arterial malformations were also assessed by DSCT. For 17 patients undergoing cardiac catheterization, the DSCT-based diameters of MPA and AAO were correlated with their pressures as measured by catheterization...

INTRODUCTION AND OBJECTIVES: Transcatheter aortic-valve implantation (TAVI) is an accepted treatment for patients with severe aortic stenosis and high surgical risk. However, there is lack in data about TAVI in low-risk patients that are already being treated with this therapy in some clinical contexts. METHODS: A retrospective analysis of patients treated with transfemoral TAVI using Edwards Sapien prosthesis in one center was performed, classifying the patients into three groups according to the surgical risk (high/intermediate/low risk for STS score>8/4-8/<4)...

Value-based care emphasizes achieving the greatest overall health benefit for every dollar spent. We present an interesting case of stroke, which made us consider how frequently health care providers are utilizing value-based care. A 73-year-old Caucasian, who was initially admitted for a hypertensive emergency, was transferred to our facility for worsening slurring of speech and left-sided weakness. The patient had an extensive chronic cerebrovascular disease, including multiple embolic type strokes, mainly in the distribution of the right temporal-occipital cerebral artery and transient ischemic attacks (TIAs)...

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...

Takayasu's arteritis is a rare systemic vasculitis mainly affecting the aorta and its major branches. Previous studies have suggested that almost half of the Asian Takayasu's patients have renal artery involvement. However, due to the rarity of the disease, little is known about renal artery involvement in Chinese Takayasu's arteritis patients. Here, we retrospectively reviewed and analyzed 411 patients diagnosed with Takayasu's arteritis in our center to explore the clinical features of renal artery involvement in this group of patients...

BACKGROUND: Cryoballoon-based pulmonary vein isolation (CB-PVI) has been widely used for the treatment of atrial fibrillation. Although generally safe and effective, the procedure may be associated with pulmonary vein (PV) stenosis and bronchial or esophageal injury. The mechanisms leading to these complications have not been studied in detail. Our aim was to examine acute effects of cryoballoon on the pulmonary vessel and right heart pressures as well as PV wall morphology. METHODS AND RESULTS: In 8 patients (5 men, mean age 55±14 years) undergoing CB-PVI, pressure in each PV was measured by catheter located inside the PV directly before and after CB-PVI...

Congenital pulmonary vein stenosis is a rare entity caused due to failed incorporation of common right and/or left pulmonary vein into the left atrium. Below is a case report of a combination of predominantly left-sided pulmonary vein stenosis with right pulmonary artery branch stenosis. The patient was an adolescent boy with mild symptoms. Clinical examination revealed features of pulmonary artery hypertension. Echocardiography and computed tomography scan were done to confirm the disease.
