Secondary mitral regurgitation: Maintaining coherence with the American Society of Echocardiography grading guidelines, which proportionality concept best predicts prognosis in the real world?

Introduction: Proportionality of secondary mitral regurgitation (sMR) may be a key factor in deciding whether a patient may benefit from mitral intervention. The aim of this study was to evaluate the prognostic value of two different concepts of proportionality and assess their ability to improve MR stratification proposed by the American Society of Echocardiography (ASE) guidelines.

Methods: We conducted a retrospective analysis in patients with reduced left ventricular ejection fraction (LVEF) (<50%) and at least mild sMR.

The many paths to diagnose diaphragmatic paralysis: Cardiopulmonary ultrasound on stage.

Abnormal diaphragmatic motion (ADM) due to phrenic nerve injury is a recognized complication of cardiac surgery and several diagnostic techniques can be used to determine the diagnosis. Due to its relationship with the diaphragm, cardiac kinetics is affected by the abnormal movement of the diaphragm in cases of left hemidiaphragm paralysis. The authors present a case of diaphragmatic paralysis in which the initial diagnosis is made through echocardiography.

Assessing proportionate and disproportionate functional mitral regurgitation with individualized thresholds.

Aims: The concept of proportionate/disproportionate functional mitral regurgitation (FMR) has been limited by the lack of a simple way to assess it and by the paucity of data showing its prognostic superiority. The aim of this study was to evaluate the prognostic value of an individualized method of assessing FMR proportionality.

Methods And Results: We retrospectively identified 572 patients with at least mild FMR and reduced left ventricular ejection fraction (<50%) under medical therapy.

Long-term assessment of the Ross procedure in adults: Clinical and echocardiographic follow-up at 20 years.

Introduction: The Ross procedure is an alternative to standard aortic valve (AV) replacement in young and middle-aged patients. However, durability and incidence of reoperation remain a concern for most cardiac surgeons. Our aim was to assess very long-term clinical and echocardiographic outcomes of the Ross procedure.

Impact of Renal Sympathetic Denervation on Left Ventricular Structure and Function at 1-Year Follow-Up.

Background: Catheter-based sympathetic renal denervation (RDN) is a recent therapeutic option for patients with resistant hypertension. However, the impact of RDN in left ventricular (LV) mass and function is not completely established. Our aim was to evaluate the effects of RDN on LV structure and function (systolic and diastolic) in patients with resistant hypertension (HTN).

[Successful cardiac resynchronization therapy in a patient with heart failure and ischemic mitral regurgitation: importance of septal flash].

We describe the case of a 76-year-old man with a history of ischemic heart disease and functional mitral regurgitation who over the previous six months had experienced worsening of functional class (NYHA III/IV) under optimal medical therapy, without ischemic symptoms and with negative ischemic tests. Mitral valve annuloplasty was considered. As the patient presented left bundle branch block on the surface ECG, cardiac resynchronization therapy (CRT) was also considered.

Load-independent parameters of diastolic and systolic function by speckle tracking and tissue doppler in hemodialysis patients.

Background: Assessment of diastolic function using conventional Doppler techniques is limited by their significant dependence on volume load status. Whether new echocardiographic methods are load-independent in evaluating left ventricular systolic and diastolic function remains controversial.

Objective: The aim of this study was to identify load-independent echocardiographic parameters for systolic and diastolic function in end-stage renal disease (ESRD) patients undergoing hemodialysis (HD) and to evaluate agreement between the new methods.
