Evaluation of atrial function by 2D strain echocardiography in patients with atrial fibrillation
2012
Abstract Objectives To evaluate atrial function by 2D strain in patients with atrial fibrillation (AF) and normal or slightly increased atrial size and to verify whether lower atrial strain is associated with more frequent AF recurrences. Materials and methods We studied 50 patients with AF, mean age 59.6 ± 13 years and 50 age-and gender-matched controls. We analyzed left atrial function through 2Dstrain imaging, after the re-establishment of sinus rhythm (SR) and we investigated about the recurrences of the arrhythmia. Results Atrial strain (AS) was lower in AF patients vs controls (LA p Conclusions The assessment of atrial function by strain imaging might help to identify patients who nee…
Role of CRT upgrading in pacing induced heart failure: A case report
2014
Abstract We submit a case report of a 78-year-old male came to our department for systolic heart, failure (EF of 25%). He has clinical history of recurring atrial tachycardia and atrial flutter previously treated in our department unsuccessfully with antiarrhythmic drug therapy. The echocardiographic evidence of left atrial enlargement (left atrium area 40 cm 2 ) and the clinical history of permanent atrial tachycardia has discouraged any attempt of substrate ablation. As it is impossible get rhythm and rate control with drug therapy, the patient was subjected to an "ablate and pace" procedure with implantation of a VVIR mode pacemaker. Also, for the absence of indications (QRS width During…
The Incidence of Audible Steam Pops Is Increased and Unpredictable With the ThermoCool® Surround Flow Catheter During Left Atrial Catheter Ablation: …
2015
Audible Steam Pops During Left Atrial Catheter AblationIntroduction Open irrigated radiofrequency (RF) ablation catheters with a porous tip (56 holes, TC-SF) permit delivering RF energy in a temperature-controlled mode without temperature rise. This prospective observational study investigated the association of different catheter parameters on the occurrence of audible steam pops during left atrial (LA) ablation. Methods and Results A total of 226 patients underwent TC-SF catheter ablation for atrial fibrillation. RF power delivery, impedance and catheter tip temperature were continually recorded throughout the ablation. Pulmonary vein isolation was performed with a maximum of 27 W and LA …
Transcatheter indirect mitral annuloplasty induces annular and left atrial remodelling in secondary mitral regurgitation
2020
Abstract Aims Mitral annuloplasty using the Carillon Mitral Contour System (CMCS) reduces secondary mitral regurgitation (SMR) and leads to reverse left ventricular remodelling. The aim of this study was to evaluate the effect of the CMCS on the mitral valve annulus (MA) and left atrial volume (LAV). Methods and results We retrospectively evaluated the data of all patients treated with the CMCS at our centre. Using transthoracic echocardiography, MA diameters were assessed by measuring the anterolateral to posteromedial extend (ALPM) and the anterior to posterior (AP) dimensions, respectively. Also, LAV and left ventricular end‐diastolic volume (LVEDV) were assessed. Patients were examined …
Abstract P153: Early Changes in Left-Atrial and Left-Ventricular Geometry and Function in Women After Preeclampsia as Detected by Cardiac Magnetic Re…
2019
Objectives: Preeclampsia (PE), the leading cause of maternal and neonatal morbidity and mortality, is associated with an increased long-term risk for cardiovascular disease (CVD). We aimed to characterize myocardium and investigate potential functional and structural cardiac alterations in asymptomatic women after PE using cardiovascular magnetic resonance (CMR) imaging. Methods and Results: We performed a post-pregnancy case-control study (clinicaltrials.gov ID: NCT03313063). In total, 22 cases and 23 controls were recruited. Participants were matched by age, BMI and parity. Hemodynamic and morphologic characteristics of the myocardium were assessed using established and innovative CMR te…
CRT-727 Percutaneous Balloon Atrial Septostomy for Direct Left Heart Decompression in Patients on Extra Corporeal Membrane Oxygenation
2014
Severe myocardial dysfunction and added afterload from the Extra Corporeal Membrane Oxygenation (ECMO) arterial cannula may lead to significant rise in left ventricular (LV) end-diastolic and left atrial (LA) pressures. This may result in ischemia, lower likelihood of ventricular recovery and hence
