Stress cardiomyopathy (Tako-Tsubo) following radiofrequency ablation in the right ventricular outflow tract

A 44-year-old female undergoing radiofrequency ablation in the right ventricular outflow tract for symptomatic, frequent premature ventricular contractions developed stress cardiomyopathy (Tako-Tsubo). Stress cardiomyopathy was probably due to hyperadrenergic state induced by the procedure itself, dobutamine infusion, sympathetic nerve stimulation at the ablation site, and parasympathetic withdrawal with atropine administration.

Premature atrial contraction-induced cardiomyopathy

A 33-year-old woman presented to her primary care physician with a 4-year history of palpitations. Twelve-lead electrocardiogram showed normal sinus rhythm with frequent, monomorphic premature atrial contractions (PACs) ( Panel A ). Premature atrial contraction load …

Assessment of right ventricular systolic function in heart transplant patients: Correlation between echocardiography and cardiac magnetic resonance imaging. Investigation of the accuracy and reliability of echocardiography

Right ventricular (RV) function has great impact on the survival of heart transplantation recipients; therefore, careful evaluation is of high clinical importance. However, there is no standard conventional echocardiographic parameter to assess RV systolic function. Herein, we evaluated the correlation between echocardiographic parameters of RV systolic function and ejection fraction assessed by cardiac magnetic resonance imaging (MRI RVEF) in heart transplantation recipients.

COMPARISONS OF INVASIVE AND NON-INVASIVE CARDIAC OUTPUT MEASURMENT METHODS IN PULMONARY HYPERTENSION

Background: Current guidelines recommend right heart catheterization and invasive cardiac output (CO) measurement with Fick or Thermodilution (TD) for diagnosis and clinical follow-up in pulmonary hypertension (PH). There is lack of evidence for routine clinical use of non- invasive measurements of

EARLY DETECTION OF IMPAIRED LEFT VENTRICULER FUNCTION IN FIRST DEGREE RELATIVES OF PATIENS WITH IDIOPATHIC DILATED CARDIOMYOPATHY: A STRAIN IMAGING STUDY

Cardiac deformation parameters are shown to be impaired in cardiac diseases even when ejection fraction (EF) and left ventriculer (LV) diameters are normal. The aim of this study is to evaluate subclinical myocardial dysfunction with strain imaging in first-degree relatives of patients with

Assessment of Right Ventricular Systolic Function in Heart Transplant Patients: Correlation between Echocardiography and Cardiac Magnetic Resonance Imaging. Investigation of the Accuracy and Reliability of Echocardiography

Purpose Right ventricular functions have affects on survival of heart transplantation patients. There is no standart echocardiographic evaluation methods for RV systolic functions. In this study, the correlation between the echocardiographic parameters for evaluating the RV systolic function and right ventricular ejection fraction (RVEF) calculated by cardiac magnetic resonance imaging (MRI- MR RVEF), are analyzed. Methods and Materials 43 Patients with at least 6 months over heart transplantation were included in this study. First echocardiography (2D, tissue Doppler and strain imaging) and cardiac MRI and afterwards endomyocardial biopsy and right heart catheterization were performed in six hours period. Results Only the echocardiographic parameter RV FAC was associated with MRI RVEF (r = 0.747, p 50% and MR RVEF ≤ 50%, RVFAC 48,5% value had 90,5% sensitivity and 90,5% specificity.(AUC:0,96) In the case grup defined as “normal” (n = 30). MR RVEF= 44.5% was considered as the lower referance limit and MR RVEF Conclusions RVFAC is the only parameter correlated with MR RVEF, should be used for heart transplantation patients rutine follow up.
