Prognostic Impact of Right Ventricular Diastolic Dysfunction in Patients Undergoing Isolated Coronary Artery Bypass Grafting.

Background: Right ventricular diastolic dysfunction (RVDD) increases the volume load on the right ventricle. We aimed to evaluate the association of RVDD with perioperative outcomes in patients undergoing isolated coronary artery bypass graft surgery (CABG).

Methods: This single-center observational study included all consecutive isolated CABG patients with a left ventricular ejection fraction (LVEF)>40% from May 2022 to May 2023 who were evaluated for RV diastolic function by transthoracic echocardiography.

The correlation between conventional echocardiography and two-dimensional speckle strain imaging for evaluating left atrial function in patients with moderate to severe mitral stenosis.

Aim: We intended to assess the left atrial deformation parameters, using two-dimensional speckle tracking (2DSTE) and transesophageal echocardiography (TEE), and determine the correlation between these two techniques in order to recognize the patients at risk for cardioembolic events.

Method: Strain and strain rate were measured using 2DSTE among 26 patients in sinus rhythm, with isolated moderate to severe mitral stenosis. Left atrial (LA) volume parameters (maximum, minimum and preatrial contraction) were measured.

Imaging of heart acoustic based on the sub-space methods using a microphone array.

Background And Objectives: Heart disease is one of the leading causes of death around the world. Phonocardiogram (PCG) is an important bio-signal which represents the acoustic activity of heart, typically without any spatiotemporal information of the involved acoustic sources. The aim of this study is to analyze the PCG by employing a microphone array by which the heart internal sound sources could be localized, too.

Association between Latest Activated Sites in the Left Ventricle and Akinetic Segments in Patients with Ischemic Cardiomyopathy.

It is not clear whether the latest activation sites in the left ventricle (LV) are matched with infracted regions in patients with ischemic cardiomyopathy (ICM). We aimed to investigate whether the latest activation sites in the LV are in agreement with the region of akinesia in patients with ICM. Data were analyzed in 106 patients (age = 60.

Correlation between systolic deformation and dyssynchrony indices and the grade of left ventricular hypertrophy in hypertensive patients with a preserved systolic ejection fraction undergoing coronary angiography, based on tissue Doppler imaging.

Objectives: The purpose of this study was to investigate whether systolic mechanical dyssynchrony occurs in hypertensive patients with a normal coronary artery and a normal ejection fraction and its relationship with different degrees of left ventricular (LV) hypertrophy.

Methods: A total of 125 angiographically normal coronary patients (42.4% male; mean age ± SD, 57.

A comparison between size of the occluder device and two-dimensional transoesophageal echocardiographic sizing of the ostium secundum atrial septal defect.

Objectives: Transcatheter closure of a secundum atrial septal defect (ASD II) has become an effective alternative for surgical treatment. In this study we evaluated the correlation between the two-dimensional transoesophageal echocardiographic (2D TEE) sizing of ASDs and the actual diameter of occluders in patients undergoing device closure.

Methods: The records of 54 patients who underwent transcatheter ASD closure were reviewed.

Evaluation of subclinical left ventricular dysfunction in diabetic patients: longitudinal strain velocities and left ventricular dyssynchrony by two-dimensional speckle tracking echocardiography study.

Background: We evaluated left ventricular (LV) subclinical systolic dysfunction in diabetes mellitus patients using two-dimensional speckle tracking echocardiography (STE) for early detection of changes in LV longitudinal strain (ST) or synchronized contraction.

Methods: To determine ST and LV dyssynchrony, 37 normal coronary and normotensive diabetes mellitus patients with LV ejection fraction >50% were enrolled and compared to 39 nondiabetic normal coronary and LV function subjects. The cases underwent standard conventional transthoracic echocardiography and tissue Doppler imaging (TDI) and STE.

Prevalence and determinants of elevated high-sensitivity cardiac troponin T in hypertrophic cardiomyopathy.

Background: This study was designed to evaluate the prevalence and determinants of increased high-sensitivity cardiac troponin T (hs-cTnT) as a marker of cardiac injury in patients with hypertrophic cardiomyopathy (HCM).

Methods: A total of 98 consecutive patients with HCM (71.4% males; mean age 51.

Post-traumatic chordae rupture of tricuspid valve.

Blunt injury to the chest can affect any one or all components of the chest wall and thoracic cavity. The clinical presentation of patients with blunt chest trauma varies widely and ranges from minor reports of pain to florid shock. Traumatic tricuspid valve regurgitation is a rare cardiovascular complication of blunt chest trauma.

Effects of cardiac rehabilitation program on right ventricular function after coronary artery bypass graft surgery.

Background: Cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (CABG). However, the effect of this program on right ventricular function following CABG is unclear. The aim of this study was to evaluate the impact of cardiac rehabilitation on the right ventricular (RV) function in a cohort of patients who underwent CABG.

Unusual presentation and echocardiographic management of giant mural endocarditis occurring simultaneously with aneurysmatic aorta.

We describe a 32-year-old man who presented in a febrile, unconscious state with unusual staphylococcal endocarditis. We diagnosed the patient's illness by using transthoracic echocardiography (TTE), which revealed a giant vegetation on the left ventricular lateral wall. The patient had history of aortic valve replacement and coarctoplasty.
