Alcohol septal ablation (ASA) in hypertrophic obstructive cardiomyopathy reduces left ventricular outflow tract gradients. A third of patients do not respond; inaccurate localisation of the iatrogenic infarct can be responsible. Transthoracic echocardiography (TTE) using myocardial contrast can be difficult in the laboratory environment. Intra-cardiac echocardiography (ICE) provides high-qualit...

BACKGROUND AL amyloidosis and multiple myeloma result in extracellular deposition of insoluble fibrillary protein in tissue and organs. Untreated median survival is very poor, and even worse with cardiac involvement. Chemotherapy and peripheral blood stem cell transplantation (PBSCT) have been shown to dramatically improve survival, with hematologic remission documented. Regression of cardiac c...

AIMS Transoesophageal echocardiography (TEE) with contrast administration is still considered as the reference method for the detection of patent foramen ovale (PFO) with interatrial shunt, but it is a semi-invasive exam. The aim of the present study is to evaluate a role of two- and three-dimensional transthoracic echocardiography (TTE and R3DTE) as a diagnostic alternative to transcranial Dop...

background: transcatheter occlusion of the patent ductus arteriosus (pda) is a minimally invasive treatment. the appropriate device size is chosen based on the angiographic measurement of the pda . the current study aimed to assess the relationship between the transthoracic echocardiographic (tte) measurements of the pda prior to the occlusion procedure and the actual size of the deployed devic...

— The Compton Gamma Ray Observatory (CGRO) observed many types of data and one of them is the time-tagged photon events (TTE data). We use the Bayesian block analysis, using Bayesian statistics, analyses the TTE data. Our results; calculations of duration (T100), count rates (burst photon numbers in different channels) and count peaks (in 64, 16 and 4 ms). We present the duration, the peak dura...

OBJECTIVES The aim of this study, undertaken in patients who underwent mitral valve (MV) repair surgery, was to evaluate the feasibility and accuracy of 3-dimensional (3D) transthoracic (TTE) and transesophageal (TEE) echocardiography in the evaluation of MV pathology. BACKGROUND A pre-operative assessment of MV anatomy is essential to surgical design in patients undergoing MV repair. Althoug...

OBJECTIVE To analyze survival differences between transthoracic esophagectomy (TTE) and limited transhiatal esophagectomy (THE) in clinically (cT3) and pathologically (pT3) staged advanced tumors without neoadjuvant treatment. BACKGROUND Debate exists whether in the type of resection in locally advanced cancer plays a role in prognosis and whether THE is a valuable alternative to TTE regardin...

The patient underwent transthoracic echocardiography (TTE), which disclosed significant left ventricular dysfunction and cystic mass of heterogeneous content on the lateral wall of the right atrium (RA). Cardiac magnetic resonance (CMR) imaging confirmed the TTE findings. Due to the high probability of thrombus, oral anticoagulation and echocardiographic control were chosen. The patient had ref...

Preoperative information concerning the severity and etiology of MR is very important for selecting the most appropriate surgical strategy. Ruptured chordae tendineae (RCT) are one of the most important preoperative findings. We compared the diagnostic power of transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) to detect RCT in patients with MR. We studied 61 patien...

Patent foramen ovale (PFO) is a remnant of the fetal circulation exist in 20% of the general population. The purpose of our study was to compare of transthoracic echocardiography (TTE) and contrast-transcranial Doppler sonography (c-TCD) in the diagnosis and quantification of PFO with or without the Valsalva maneuver (VM).We studied 106 patients with a high clinical suspicion for PFO prospectiv...
