Right atrial deformation analysis in isolated left ventricular noncompaction - insights from the three-dimensional speckle tracking echocardiographic MAGYAR-Path Study.

Objective: Isolated left ventricular noncompaction (ILVNC) is a rare cardiomyopathy characterized by a prominent trabecular meshwork and deep intertrabecular recesses. The present study aimed to examine right atrial (RA) volumes, volume-based functional properties and strains by three-dimensional speckle-tracking echocardiography (3DSTE) in ILVNC patients.

Methods: The study group consisted of 13 patients with ILVNC (mean age: 54.

Short-term beat-to-beat variability of the QT interval is increased and correlates with parameters of left ventricular hypertrophy in patients with hypertrophic cardiomyopathy.

Stratification models for the prediction of sudden cardiac death (SCD) are inappropriate in patients with hypertrophic cardiomyopathy (HCM). We investigated conventional electrocardiogram (ECG) repolarization parameters and the beat-to-beat short-term QT interval variability (QT-STV), a new parameter of proarrhythmic risk, in 37 patients with HCM (21 males, average age 48 ± 15 years). Resting ECGs were recorded for 5 min and the frequency corrected QT interval (QTc), QT dispersion (QTd), beat-to-beat short-term variability of QT interval (QT-STV), and the duration of terminal part of T waves (Tpeak-Tend) were calculated.

Increased Short-Term Beat-To-Beat Variability of QT Interval in Patients with Acromegaly.

Cardiovascular diseases, including ventricular arrhythmias are responsible for increased mortality in patients with acromegaly. Acromegaly may cause repolarization abnormalities such as QT prolongation and impairment of repolarization reserve enhancing liability to arrhythmia. The aim of this study was to determine the short-term beat-to-beat QT variability in patients with acromegaly.

[Relationship between early myocardial reperfusion assessed by videodensitometry and late left ventricular function. Results following invasive treatment of acute myocardial infarction].

Introduction: It is known that there is a relationship between myocardial perfusion and left ventricular function.

Aim: The aim of the current study was to examine the relationship between myocardial reperfusion as assessed by videodensitometry on coronary angiograms following invasive treatment of ST elevation myocardial infarction and magnetic resonance imaging-derived late left ventricular function.

Method: The study included 25 patients with ST elevation myocardial infarction.

Quantification of changes in septal strain after alcohol septal ablation in hypertrophic obstructive cardiomyopathy-cases from the three-dimensional speckle tracking echocardiographic MAGYAR-path study.

Patients with hypertrophic obstructive cardiomyopathy undergoing alcohol septal ablation are presented. Three-dimensional speckle tracking echocardiography (3DSTE) is a new, noninvasive tool for quantification of myocardial deformation. In both cases, 3DSTE was performed 1 day before and 3 days after alcohol septal ablation to quantify changes in septal strain of ablated area.

Hypertrophic cardiomyopathy is associated with abnormal echocardiographic aortic elastic properties and arteriograph-derived pulse-wave velocity.

Objective: Hypertrophic cardiomyopathy (HCM) is a genetic cardiac disease and defined by the presence of unexplained left ventricular hypertrophy (LVH). Vascular alterations are frequently associated with HCM including microvascular and/or peripherial endothelial dysfunction. This study was designed to evaluate echocardiographic ascending aortic elastic properties and arteriograph-derived pulse-wave velocity (PWV) and augmentation index (Aix) in HCM.

Correlations between aortic stiffness and parasympathetic autonomic function in healthy volunteers.

Cardiovascular autonomic dysfunction and alterations in vascular elasticity are known complications of several disorders, including diabetes mellitus, hypertension, hypercholesterolemia, aging, and chronic kidney disease. The current study was designed to test whether a relationship existed between pulse wave velocity (PWV), augmentation index (AIx), aortic elastic properties, and cardiovascular autonomic function in healthy volunteers. The study comprised 25 healthy volunteers, whose aortic strain, distensibility, and stiffness index were measured by echocardiography, whereas PWV and AIx were evaluated by Arteriograph (TensioMed, Budapest, Hungary) in all cases.

Correlations between Arteriograph-derived pulse wave velocity and aortic elastic properties by echocardiography.

Introduction: There is an increased scientific interest on the evaluation of parameters characterizing aortic elasticity. The current study was designed to compare two characteristics of aortic distensibility: Arteriograph-derived pulse wave velocity (PWV) and augmentation index standardized to 80 per minutes heart rate (AIx80) and aortic elastic properties by echocardiography.

Methods: The study comprised 21 adult healthy volunteers.

[Coronary artery dissection in the postpartum period--a case study].

Spontaneous coronary dissection is a rare condition occurring more often in women, with a higher frequency during the peripartum period. No specific aetiology has been defined to this uncommon, but often fatal disease. We describe the case of a young woman admitted to our intensive care unit with ECG-findings of acute anterior myocardial infarction presented one week after delivery.

Obesity is associated with aortic enlargement and increased stiffness: an echocardiographic study.

Background: Obesity may be associated with early vascular changes. The current study was designed to assess the relationship between obesity and aortic stiffness in two populations, one aged 18-40 years and one aged 41-64 years.

Methods: The study complied 121 subjects, all of them underwent a physical examination, transthoracic echocardiography and blood pressure measurement.

Aortic stiffness is increased in acromegaly--a transthoracic echocardiographic study.

Background: Acromegaly is associated with increased cardiovascular risk. Recent studies suggested a direct effect of growth hormone and insuline-like growth factor 1 excess on the vasculature over the conventional risk factors. The aim of the present study was to evaluate the stiffness of ascending aorta by means of transthoracic echocardiography (TTE) in patients with acromegaly.

Increased aortic stiffness in glycogenosis type 2 (Pompe's disease).

Background: Pompe's disease, also known as acid maltase deficiency or glycogen storage disease type II, is an autosomal recessive disorder in which deficient activity of the enzyme acid alpha-glucosidase causes intra-lysosomal accumulation of glycogen in muscle and other tissues. The current study was designed to assess aortic stiffness index (beta), as a characteristic of aortic elasticity during transthoracic echocardiography in patients with Pompe's disease.

Methods: A total of 17 patients (age 44+/-8 years, 5 males) with Pompe's disease were studied.

Transthoracic echocardiographic evaluation of aortic distensibility in a Takayasu's arteritis patient.

Takayasu's arteritis (TA) is a chronic, nonspecific, rare, and segmental inflammatory disease that primarily affects the aorta and its main branches. In the present case, the aortic elastic properties were decreased (aortic distensibility was practically normal) suggesting that ascending aorta was not affected by TA. For preoperative assessment, a routine transthoracic echocardiography can be a valuable method for the noninvasive functional evaluation of ascending aorta in a patient with TA.
