Prosthetic mitral valve endocarditis.

IDCases 2020 26;21:e00891. Epub 2020 Jun 26.

Department of Cardiology, The University of Texas Health Science Center at San Antonio, San Antonio, TX, USA.

endocarditis is a fatal source of valvular infection with a near 100 % mortality rate if pharmacotherapy and valve-replacement surgery are not initiated swiftly after diagnosis. Complicating its diagnosis is the low yield for growth on standard blood culture and time requirements for molecular diagnostic tools to return a result. endocarditis of the mitral valve presents as valvular vegetations that reduce the caliber of the mitral valve and can cause syncope as in the case of mitral stenosis with subsequent valve failure, left atrial enlargement, and prospective cardiovascular failure.

Neurosurg Rev 2020 Jul 4. Epub 2020 Jul 4.

Medical and Molecular Genetics, Indiana University Health Physicians, Indianapolis, IN, USA.

Atlanto-axial instability (AAI) is common in the connective tissue disorders, such as rheumatoid arthritis, and increasingly recognized in the heritable disorders of Stickler, Loeys-Dietz, Marfan, Morquio, and Ehlers-Danlos (EDS) syndromes, where it typically presents as a rotary subluxation due to incompetence of the alar ligament. This retrospective, IRB-approved study examines 20 subjects with Fielding type 1 rotary subluxation, characterized by anterior subluxation of the facet on one side, with a normal atlanto-dental interval. Subjects diagnosed with a heritable connective tissue disorder, and AAI had failed non-operative treatment and presented with severe headache, neck pain, and characteristic neurological findings.

Cantú syndrome versus Zimmermann-Laband syndrome: Report of nine individuals with ABCC9 variants.

Eur J Med Genet 2020 Jul 2:103996. Epub 2020 Jul 2.

Institute of Human Genetics, University Medical Center Hamburg-Eppendorf, Hamburg, Germany. Electronic address:

Cantú syndrome (CS) is a rare developmental disorder characterized by a coarse facial appearance, macrocephaly, hypertrichosis, skeletal and cardiovascular anomalies and caused by heterozygous gain-of-function variants in ABCC9 and KCNJ8, encoding heterooctameric ATP-sensitive potassium (K) channels. CS shows considerable clinical overlap with Zimmermann-Laband syndrome (ZLS), a rare condition with coarse facial features, hypertrichosis, gingival overgrowth, intellectual disability of variable degree, and hypoplasia or aplasia of terminal phalanges and/or nails. ZLS is caused by heterozygous gain-of-function variants in KCNH1 or KCNN3, and gain-of-function KCNK4 variants underlie the clinically similar FHEIG (facial dysmorphism, hypertrichosis, epilepsy, intellectual disability/developmental delay, and gingival overgrowth) syndrome; KCNH1, KCNN3 and KCNK4 encode potassium channels.

Myotonic dystrophy type 1 and high ventricular vulnerability at the electrophysiological evaluation: ICD yes or not?

Acta Myol 2020 Mar 1;39(1):32-35. Epub 2020 Mar 1.

Department of Cardiac Electrophysiology and Pacing, Istituto Clinico Sant'Ambrogio, Milan, Italy.

A significant number of sudden death (SD) is observed in myotonic dystrophy (DM1) despite pacemaker implantation and some consider the ICD to be the preferential device in patients with conduction disease. According to the latest guidelines, prophylactic ICD implantation in patients with neuromuscular disorder should follow the same recommendations of non-ischemic dilated cardiomyopathy, being reasonable when pacing is needed. We here report a case of DM1 patient who underwent ICD implantation even in the absence of conduction disturbances on ECG and ventricular dysfunction/fibrosis at cardiac magnetic resonance.

Paroxysmal Ventricular Standstill: A Rare Cardiac Manifestation of Syncope.

Am J Case Rep 2020 Jun 17;21:e924381. Epub 2020 Jun 17.

Emergency Department, Charing Cross Hospital, Imperial College Healthcare NHS Trust, London, United Kingdom.

BACKGROUND Transient abrupt loss of consciousness due to sudden but pronounced decrease in cardiac output caused by a change in heart rate and rhythm is termed Stokes-Adams disease. Causes of Stokes-Adams syndrome are 1) transition from normal rhythm to high grade block, 2) slowing of idioventricular rhythm in the course of complete heart block, and 3) abnormal ventricular rhythm such as ventricular tachycardia and ventricular fibrillation. Paroxysmal ventricular standstill is one of the rarest causes of Stokes-Adams attack. Read More

Case of vago-glossopharyngeal neuralgia secondary to metastatic oropharyngeal cancer.

BMJ Case Rep 2020 Jun 28;13(6). Epub 2020 Jun 28.

Department of Critical Care Medicine, Mayo Clinic, Jacksonville, Florida, USA.

Glossopharyngeal neuralgia (GN) is a rare pain syndrome caused by compression of the glossopharyngeal nerve. It is typically idiopathic and often goes misdiagnosed because of its similarities to trigeminal neuralgia. Vago-glossopharyngeal neuralgia, an even rarer subset of GN, occurs when the pain is accompanied by syncope and/or arrhythmia. Read More

Pitfalls in Scalp High-Frequency Oscillation Detection From Long-Term EEG Monitoring.

Front Neurol 2020 2;11:432. Epub 2020 Jun 2.

Department of Neurology, Christian-Doppler Medical Centre, Centre for Cognitive Neuroscience, Paracelsus Medical University, Salzburg, Austria.

Intracranially recorded high-frequency oscillations (>80 Hz) are considered a candidate epilepsy biomarker. Recent studies claimed their detectability on the scalp surface. We aimed to investigate the applicability of high-frequency oscillation analysis to routine surface EEG obtained at an epilepsy monitoring unit. Read More

From Other Journals: A Review of Recent Articles in Pediatric Cardiology.

Authors:
Tarek Alsaied

Pediatr Cardiol 2020 Jun 23. Epub 2020 Jun 23.

Heart Institute, Cincinnati Children's Hospital Medical Center, 3333 Burnet Avenue, Cincinnati, OH, 45229, USA.

In this review, we provide a brief description of recently published articles addressing topics relevant to pediatric cardiologists. Our hope is to provide a summary of the latest articles published recently in other journals in our field. The articles address the following: (1) transcatheter closure of sinus venous atrial septal defect which is feasible in adults with careful planning, (2) exercise echocardiography in children with hypertrophic cardiomyopathy which was found to be very helpful to identify low-risk patients when there is no gradient at rest or during exercise, (3) features of Fontan patients with normal exercise capacity who typically report more active life style and have less complications during the post-Fontan admissions, (4) the natural history of Anderson-Tawil syndrome which is characterized by high incidence of life-threatening arrhythmogenic events especially when there is history of syncope, ventricular tachycardia, or the use of amiodarone, (5) pulmonary artery banding in complete atrioventricular septal defects which were found to be a safe alternative to early complete repair and served as a bridge to biventricular repair with variable effect on common atrioventricular valve regurgitation and (6) tricuspid valve interventions (TVI) in patients undergoing pulmonary valve replacement (PVR) which further reduce tricuspid regurgitation beyond what is expected in PVR alone without increasing early complications or hospital length of stay.

Isolated Exercise-Induced Pulmonary Hypertension Associates with Higher Cardiovascular Risk in Scleroderma Patients.

J Clin Med 2020 Jun 18;9(6). Epub 2020 Jun 18.

Institute of Cardiology, University of Pisa, 56124 Pisa, Italy.

Background And Aim: Isolated exercise-induced pulmonary hypertension (ExPH) associates with cardiovascular (CV) events in patients with left heart disease. We investigated its prognostic significance in scleroderma patients at risk for pulmonary arterial hypertension (PAH).

Methods: In 26 consecutive scleroderma female patients with either low ( = 13) or intermediate probability ( = 13) of pulmonary hypertension (PH) at rest, we evaluated, both at time 0 and 1 year, prognostic determinants of CV risk: onset or progression of heart failure/syncope; worsening of functional class; functional performance at the 6-minute walking test and at cardiopulmonary exercise test; right atrial area; and pericardial effusion.
