Flash pulmonary edema frequently develop in case of bilateral renal artery stenosis and unilateral renal artery stenosis with functional solitary kidney. In some rare cases, unilateral renal artery stenosis with bilaterally functional kidneys may also lead to flash pulmonary edema. Here, we present a case of flash pulmonary edema caused by accessory renal artery stenosis. To our knowledge, it is the first case reported in the literature.

Dhaval R Parekh, Zvonimir Krajcer
Transcatheter pulmonary valve implantation (TPVI) within a failed bioprosthetic valve is safe and effective Coronary artery compression is a potential risk, requiring careful preimplantation balloon dilation testing Prestenting is required for TPVI in stentless conduits Improvements in right ventricular volume, pressure, pulmonary stenosis, and regurgitation can be maintained in the intermediate term Long-term risk for Melody valve endocarditis and valve dysfunction necessitates careful monitoring.

INTRODUCTION: Pulmonary artery aneurysms are a rare entity. Etiologies of these findings are multiple, but they are exceptionally associated with Fallot's Tetralogy. In this study, we present an unusual case of an important aneurysm of the left pulmonary artery associated with Fallot's Tetralogy disease. CASE PRESENTATION: A 30-year-old woman has been admitted for dyspnea and cyanosis. The data which had been obtained from echocardiography, cardiac catheterization, and angio-magnetic resonance imaging (MRI) suggested the existence of an important aneurysm of the left pulmonary artery associated with a regular Fallot's disease with a pulmonic stenosis...

Anomalous origin of the circumflex coronary artery from the right pulmonary artery is rare, and symptoms are related to the collateralization and amount of myocardium that it supplies. A 50-year-old woman with severe bicuspid aortic valve stenosis had the diagnosis of anomalous origin of the circumflex coronary artery from the right pulmonary artery before valve replacement. Ligation and division of the circumflex coronary artery was performed. Myocardial ischemia was not observed. The patient was discharged after an uneventful recovery...

Introduction In traditional locations, the standard Blalock-Taussig shunt presents numerous technical difficulties for percutaneous intervention. We changed our strategy to a central type shunt (Laks-type) with end-to-side pulmonary and side-to-side aortic anastomosis. The aim of this study was to determine whether this modified strategy would allow easier percutaneous manipulation in patients with small pulmonary arteries. Methods All children with a stretchable central vascular graft who required any form of percutaneous intervention were prospectively enrolled in the study...

BACKGROUND: Information about carotid artery stenting (CAS) is largely derived from clinical trials, consensus statements, and outcomes comparisons between CAS and carotid endarterectomy. Given these limitations, the goal of this study was to identify risk factors for adverse outcomes after CAS among hospitals participating in the CAS-targeted American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). METHODS: Our study sample consisted of patients from the 2012 to 2015 CAS-targeted ACS NSQIP data set...

BACKGROUND: Left main coronary artery (LMCA) compression is increasingly recognized as a cause of angina in pulmonary arterial hypertension (PAH). OBJECTIVES: This study aimed to evaluate the prevalence of LMCA extrinsic compression from a dilated pulmonary artery (PA) in patients with PAH and angina or angina-like symptoms, determine the usefulness of screening with computed tomography coronary angiography (CTCA), and assess the safety and efficacy of percutaneous coronary interventions (PCIs)...

A 20-month-old boy with Williams syndrome had undergone multiple surgical and catheter-based interventions for resistant peripheral pulmonary arterial stenoses with eventual bilateral stent placement and conventional balloon angioplasty. He persistently developed suprasystemic right ventricular (RV) pressure. Angioplasty with a drug-coated balloon (DCB) was performed for in-stent restenosis and to remodel his distal pulmonary vessels bilaterally. This resulted in immediate improvement in the in-stent stenosis and resultant decrease in RV pressure...

OBJECTIVES: The primary objective of this study was to demonstrate that pulmonary artery (PA) debanding via cardiac catheterization using balloon angioplasty is feasible and safe in swine. The secondary objectives were to determine the acute and long-term effects of this therapy. DESIGN: This is a chronic survival experimental study in newborn swine. BACKGROUND: PA bands are used in infants for transient palliation of congenital heart defects with excessive pulmonary blood flow...

A modified Blalock-Taussig shunt (mBTS) is often employed to provide pulmonary blood flow in neonates that are born with cyanotic congenital heart defects. However, acute shunt thrombosis can occur in the postoperative period, resulting in profound cyanosis. In this case report, we describe the utility of computed tomographic angiography (CTA) in the management of a neonate with extreme cyanosis after placement of a mBTS while on extracorporeal membrane oxygenation. Using CTA, several small clots were identified in the shunt as well as stenosis of the left pulmonary artery; neither of which were identified with echocardiography...

BACKGROUND: Left atrial (LA) enlargement is frequent in patients with aortic stenosis (AS), yet its determinants and prognostic implications are poorly understood. AIMS: To identify the echocardiographic variables associated with increased LA volume index (LAVI), and test the prognostic value of LAVI in AS. METHODS: We prospectively included 715 patients with AS in sinus rhythm at enrolment. Echocardiography was performed at baseline. Median follow-up was 22...

BACKGROUND: Heart failure (HF) is a highly prevalent syndrome. Although the long-term prognostic factors have been identified in chronic HF, this information is scarcer with respect to patients with acute HF. despite available data in the literature on long-term prognostic factors in chronic HF, data on acute HF patients are more scarce. OBJECTIVES: To develop a predictor of unfavorable prognostic events in patients hospitalized for acute HF syndromes, and to characterize a group at higher risk regarding their clinical characteristics, treatment and outcomes...

To assess the value of computed tomography (CT) for non-invasive detection of pulmonary hypertension (PH) in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) and to correlate CT measurements and signs with mortality after TAVI. 257 TAVI patients (median 84 years; 134 females) with both right heart catheterisation (RHC) and CT within 3 days were retrospectively analyzed. According to guidelines PH was defined as mean pulmonary artery pressure ≥25 mmHg in RHC. CT-signs for PH assessment were evaluated...

BACKGROUND: The Melody(®) pulmonary valve has received approval for the treatment of dysfunctional right ventricular (RV) outflow tract conduits ≥16mm. AIMS: To investigate technical and clinical outcomes in patients who underwent percutaneous pulmonary valve implantation (PPVI) in conduits ≤16mm. METHODS: Eleven patients were enrolled retrospectively between 2000 and 2015 in a cardiac referral centre.

BACKGROUND: Obesity contributes to left ventricular diastolic dysfunction (LVDD) and may lead to diastolic heart failure. Weight loss (WL) after bariatric surgery (BS) may influence LV morphology and function. Using echocardiography, this study assessed the effect of WL on LV diastolic function (LVDF) and LV and left atrium (LA) morphology 6 months after BS in young women with morbid obesity. METHODS: Echocardiography was performed in 60 women with BMI ≥ 40kg/m², aged 37...

RATIONALE: Death following orthopedic surgery has become rare, but does occur. Acute myocardial infarction (AMI) can be a cause of such death, but diagnosis of AMI is often challenging, even by autopsy. PATIENT CONCERNS: We have recently experienced 2 cases of sudden death after bone fracture surgery, in which AMI and pulmonary thromboembolism were clinically suspected as causes of death. Case 1 was a 60-year-old male with a history of diabetes mellitus who died 7 days after surgery for Lisfranc dislocation fracture...
