Cor triatriatum sinister: two cases diagnosed in adulthood and a review of literature

Cor triatriatum sinister is a rare condition caused by a membrane within left atrium that separates pulmonary veins from mitral valve (10). While the condition is usually diagnosed at childhood, rare presentation during adulthood is observed when the membrane is incomplete. We report two cases of incomplete cor triatriatum sinister diagnosed during adulthood and review literature for this rare anomaly

Effect of Vitamin D and parathyroid hormone levels on the coronary slow-flow phenomenon

The presence of vitamin D, and parathyroid hormone receptors has been demonstrated in the vascular endothelium. Variations in vitamin D, and parathyroid hormone levels may affect coronary flow and cause the coronary slow-flow phenomenon (CSF). Methods: We enrolled 93 patients who had undergone coronary angiography and had near-normal coronary arteries. Blood samples were taken to determine the calcium, phosphorus, 25-hydroxy vitamin D, and parathyroid hormone levels. Vitamin D deficiency was defined as a serum 25-hydroxy vitamin D level of less than 20 ng/mL. We divided the study population into two groups according to thrombolysis in myocardial infarction frame count (TFC) levels. Results: Patients with TFC ?27 were in the control group (n = 39), and those with TFC >27 were in the CSF group (n = 54). 25-Hydroxy vitamin D levels were similar in both groups: 17.5 [3.3-36.1] ng/ml in the CSF group and 15.2 [5.3-34] ng/ml in the control group (P = 0.129). When we analyzed TFC for each of the coronary arteries, we found a weak negative correlation between vitamin D level and TFC of the right coronary artery in the CSF group (r = -0.314, P = 0.021). Parathyroid hormone levels were similar in both groups: 48 [16-140] pg/ml in the CSF group and 52 [25-125] pg/ml in the control group (P = 0.297). Conclusion: The study failed to demonstrate a relationship between serum parathyroid hormone level and CSF. However, a weak negative correlation was found between vitamin D level and TFC of the right coronary artery. © 2019 Nigerian Journal of Clinical Practice | Published by Wolters Kluwer - Medknow

Diurnal characteristics of heart rate variability in patients with sarcoidosis

WOS: 000407250400009PubMed: 27738722The aim of this study was to evaluate autonomic nervous system function by measuring heart rate variability (HRV) in patients with sarcoidosis without known cardiac manifestations. The study comprised 61 participants, including 31 patients with sarcoidosis without known cardiac manifestations and 30 healthy volunteers. All participants underwent echocardiographic examination, 12-channel electrocardiography (ECG), and 24-h Holter monitoring. HRV parameters were determined and compared between the groups. There were no differences between groups with regard to age, body mass index, systolic and diastolic blood pressure, or heart rate at the time of admission. In the time domain analyses, the 24-h, daytime, and night-time standard deviations of all normal-to-normal RaEuroR interval (SDNN) values were significantly lower in patients with sarcoidosis than those in the controls. The frequency domain analyses showed that 24-h and daytime low-frequency (LF) values, 24-h, daytime, and night-time high-frequency (HF) values were significantly lower in the patient group compared with the control group, whereas the night-time LF/HF ratio was significantly higher. Although Holter ECG is not a diagnostic tool for cardiac sarcoidosis, the HRV parameters, especially the night-time LF/HF values, may demonstrate increased sympathetic activation in patients with sarcoidosis

Tirofiban in Takotsubo cardiomyopathy Atypical broken heart syndrome with extremely fast recovery: a case report

WOS: 000314532700012PubMed: 22930391Takotsubo cardiomyopathy, also known as broken heart syndrome, is similar to acute coronary syndrome. The absence of significant stenosis on coronary angiography and spontaneous improvement of ventricular akinesia are very important features that distinguish this syndrome from acute coronary syndromes. Despite the fact that ST segment elevations are typically encountered, atypical presentation without ECG changes should be kept in mind. We herein report the case of a 61-year-old woman who presented with mid-apical left ventricular akinesia resolving within 24 h
