Characterization of hemodynamic patterns in human fetuses with cyanotic congenital heart disease using MRI.

Ultrasound Obstet Gynecol 2021 Jun 7. Epub 2021 Jun 7.

Division of Paediatric Cardiology, Department of Paediatrics, Hospital for Sick Children, University of Toronto, Toronto, Canada.

Objectives: To characterize the distribution of blood flow and oxygen transport in human fetuses with congenital heart disease (CHD) subtypes that present with neonatal cyanosis using magnetic resonance imaging (MRI).

Methods: Blood flow was measured in the major vessels of 152 late gestation human fetuses with CHD and 40 gestational age-matched normal fetuses using cine phase contrast MRI. Oxygen saturation (SaO2) was measured in the major vessels of 57 fetuses with CHD and 40 controls. Read More

Interpreting sulfhemoglobin and methemoglobin in patients with cyanosis: An overview of patients with M-hemoglobin variants.

Int J Lab Hematol 2021 Jun 6. Epub 2021 Jun 6.

Division of Hematopathology, Mayo Clinic, Rochester, MN, USA.

Introduction: Methemoglobin (MetHb) and sulfhemoglobin (SHb) measurements are useful in the evaluation of cyanosis. When one or both values are elevated, additional analysis is important to establish the etiology of the disorder. Methemoglobinemia occurs from acquired or hereditary causes with diverse treatment considerations, while true sulfhemoglobinemia is only acquired and treatment is restricted to toxin removal.

Clinical features of bacterial meningitis among hospitalised children in Kenya.

BMC Med 2021 Jun 4;19(1):122. Epub 2021 Jun 4.

Clinical Research Department, KEMRI-Wellcome Trust Research Programme, P.O. Box 230 80108, Kilifi, Kenya.

Background: Diagnosing bacterial meningitis is essential to optimise the type and duration of antimicrobial therapy to limit mortality and sequelae. In sub-Saharan Africa, many public hospitals lack laboratory capacity, relying on clinical features to empirically treat or not treat meningitis. We investigated whether clinical features of bacterial meningitis identified prior to the introduction of conjugate vaccines still discriminate meningitis in children aged ≥60 days. Read More

Paraganglioma in an adolescent awaiting a cardiac transplant due to unrepaired congenital cyanotic heart disease and a univentricular heart: the first reported case.

BMJ Case Rep 2021 May 25;14(5). Epub 2021 May 25.

Department of Cardiology, Mater Misericordiae University Hospital, Dublin, Ireland.

We report a case of a 16-year-old adolescent male born with univentricular congenital cyanotic heart disease (CCHD) who was diagnosed with an incidental paraganglioma while awaiting a cardiac transplant. The coexistence of paraganglioma and univentricular CCHD is very rare, with no previous cases described in the literature of a patient concurrently requiring a cardiac transplant. The complex physiology associated with a common atrium, common ventricle, aortopulmonary lung perfusion and a hypoplastic left lung rendered our patient extremely vulnerable to catecholamine-mediated effects of preload, contractility and afterload.

Assessment of Tissue Perfusion Using the Peripheral Perfusion Index and Lactate Clearance in Shock in Pediatric Patients.

Shock 2021 May 19. Epub 2021 May 19.

Department of Pediatrics, Cairo University, Cairo, Egypt.

Background: Pediatric shock has a high mortality rate because many of the early clinical signs are subtle and have poor sensitivity and specificity. Pediatric shock was categorized either: compensated with normal blood pressure, poor skin perfusion (CRT >2 s, mottled, cool peripheries, peripheral cyanosis), weak peripheral pulse, age specific tachycardia, tachypnoea, and oliguria or decompensated with hypotension (SBP < 70 + (2× age in years) mm Hg and decreased mental status. The perfusion index is a non-invasive method for assessing peripheral perfusion and may be a useful marker for identifying shock early in pediatric patients. Read More

The Hemodynamics of Patent Ductus Arteriosus in Patients after Central Shunt Operation.

Comput Math Methods Med 2021 24;2021:6675613. Epub 2021 Apr 24.

Department of Catheterization Lab, Guangdong Cardiovascular Institute, Guangdong Provincial Key Laboratory of South China Structural Heart Disease, Guangdong Provincial People's Hospital, Guangdong Academy of Medical Sciences, Guangzhou, China.

A central shunt (CS) was an important surgery of systemic-to-pulmonary shunt (SPS) for the treatment of complex congenital heart diseases with decreased pulmonary blood flow (CCHDs-DPBF). There was no clear conclusion on how to deal with unclosed patent ductus arteriosus (PDA) during CS surgery. This study expanded the knowledge base on PDA by exploring the influence of the closing process of the PDA on the hemodynamic parameters for the CS model. Read More

Nailfold capillaroscopic changes of sleep apnea patients.

Microvasc Res 2021 May 10;137:104177. Epub 2021 May 10.

Samsun Education and Research Hospital, Department of Dermatology, TR-55000 İlkadim, Samsun, Turkey.

Background: Obstructive Sleep Apnea Syndrome (OSAS) have frequent association with comorbidities and this makes it an independent risk factor for cardiovascular disease. Not only endothelial dysfunction, but also arterial stiffening, increased inflammatory mediators, oxidative stress after hypoxemia that develops due to OSAS, cause vascular pathologies in all diameters of vessels. Nail bed capillaroscopy is a simple, noninvasive, useful method to examine microcirculation and evaluate nail bed capillary abnormalities in diseases that cause vascular damage. Read More

Acyanotic Truncus Arteriosus: Not a Misnomer But a True Rarity.

World J Pediatr Congenit Heart Surg 2021 May 6:21501351211000367. Epub 2021 May 6.

Department of Paediatric Cardiac Intensive Care, Sri Sathya Sai Sanjeevani International Centre for Child Heart Care and Research, Palwal, Haryana, India.

Truncus arteriosus, also referred to as common arterial trunk (CAT), is generally classified as a cyanotic congenital heart disease characterized by a single arterial trunk arising from the heart and supplying both pulmonary and systemic circulations. Cyanosis exists by virtue of it being an admixture lesion. We report a 13-year-old boy diagnosed to have type 1 CAT who was acyanotic at presentation and had all features of an operable lesion even at this age. Read More

Bailout procedure in obstructed supracardiac total anomalous pulmonary vein drainage.

Medicina (B Aires) 2021 ;81(2):282-285

Sección de Cardiología Intervencionista, Sanatorio Francés, Córdoba, Argentina.

Total anomalous pulmonary venous drainage is a rare and diverse anomaly, accounting for 1% to 3% of patients with congenital heart disease. Newborns with diagnosis of an obstructed total anomalous pulmonary venous dainage are extremely ill soon after birth and often present with severe cyanosis, pulmonary hypertension and low cardiac output requiring urgent surgical intervention. Transcatheter palliative stenting of the obstructive vertical vein can be an acceptable alternative as a bailout intervention before complete surgical correction is undertaken. Read More

Cureus 2021 Mar 24;13(3):e14079. Epub 2021 Mar 24.

Emergency Department, Imam Abdulrahman Bin Faisal University, Dammam, SAU.

Methemoglobinemia is a blood disorder in which there is an elevated level of methemoglobin. In contrast to normal hemoglobin, methemoglobin does not bind to oxygen, which leads to functional anemia. The signs of methemoglobinemia often overlap with other cardiovascular and pulmonary diseases, with cyanosis being the key sign of methemoglobinemia. Read More
