Hypertrophic cardiomyopathy and fibrosis: correlation between late gadolinium enhancement on CMR and speckle tracking imaging using Ultrasound

2015

Background Hypertrophic cardiomyopathy (HCM) is the most frequent genetic cardiovascular disorder and represents one of the most common cause of heart related sudden death in young adults. Myocardial fibrosis seems to be an independant predictor of adverse events including sudden death, ventricular arrhythmias and heart failure. While late gadolinium enhancement (LGE) on Cardiac Magnetic Resonance (CMR) is actually the gold-standard to detect fibrosis, new techniques are being evaluated such as 2D strain echocardiography.

Takotsubo Syndrome After Mitral Valve Replacement: Case Report and Brief Review of the Literature

2015

RANSIENT LEFT VENTRICULAR apical ballooningsyndrome, also known as Takotsubo or stress-inducedcardiomyopathy, is a cardiac disease characterized by transientleft ventricular dysfunction, electrocardiographic changes mim-icking an acute coronary syndrome, and release of myocardialcellular necrosis enzymes in the absence of significant lesionsof coronary arteries.

Transient mid-ventricular dyskinesia: a variant of Takotsubo syndrome

2008

Takotsubo Cardiomyopathy is characterized by a reversible systolic left ventricular apical ballooning. A new pattern of dyskinesia in the absence of angiographic evidence of coronary artery stenosis has been indicated like a variant of takotsubo cardiomiopathy: mid-ventricular akinesis with preservation of apical and basal contractilities revealed at echocardiograms and ventriculographies. We report the case of a 65 years old patient with this pattern, reverted in 4 weeks.

The Heart in Fabry Disease – from Pathogenesis to Enzyme Replacement Therapy

2010

The cardiovascular involvement in Fabry disease is progressive, and accounts for one of the major reasons for abbreviated life expectancy and increased morbidity. The majority of patients develop signs and symptoms, related to heart failure and arrhythmias. Hypertrophic cardiomyopathy, in later stages combined with myocardial fibrosis, is one of the leading features. Both genders are affected, and females develop severe cardiac Fabry disease approximately 10–15 years later in life than male patients. Diastolic dysfunction and reduced longitudinal mid-wall related systolic function are the mechanical consequences of the myocardial and epithelial changes related to accumulation of the storage…

Use of wearable cardioverter‐defibrillator in association with catheter ablation for atrial fibrillation‐related tachycardiomyopathy

2019

Implantable cardioverter‐defibrillator (ICD) implantation is not indicated in patients with potentially transient or reversible causes of sudden cardiac death (SCD). Wearable cardioverter‐defibrillator (WCD) is increasingly used for SCD prevention in patients who are temporary at high risk of ventricular arrhythmia. Hereby, we describe a case of tachycardiomyopathy successfully managed with ablation and WCD backup. Implantable cardioverter‐defibrillators are a Class I indication by American College of Cardiology/American Heart Association/Heart Rhythm Society guidelines to prevent SCD in patients with nonischemic dilated cardiomyopathy, New York Heart Association (NYHA) functional class II …

Cardiovascular outcomes after cardiac resynchronization therapy in cardiac amyloidosis

2021

Abstract Aims Cardiac resynchronization therapy (CRT) is highly effective in dilated cardiomyopathy (DCM) patients with impaired left ventricular ejection fraction (LVEF) and left bundle block branch. In cardiac amyloidosis (CA) patients, left ventricular dysfunction and conduction defects are common, but the potential of CRT to improve cardiac remodelling and survival in this particular setting remains undefined. We investigated cardiovascular outcomes in CA patients after CRT implantation in terms of CRT echocardiographic response and major cardiovascular events (MACEs). Methods and results Our retrospective study included 47 CA patients implanted with CRT devices from January 2012 to Feb…

The QRS narrowing index for easy and early identification of responder to cardiac resynchronization therapy.

2013

The rationale for cardiac resynchronization therapy (CRT) in patients with heart failure (HF) is based on the possibility of inducing substantial left ventricular reverse remodeling. It is well known that some of these patients don't benefit from this therapy (the so-called non-responders) [1,2]. No better predictors of a positive answer to CRT than pre-CRT QRS duration (QRSd) were found [3,4]. The aim of our study was to identify a parameter for an easy and early identification of responders to CRT. In this regard, according to Rickard et al., we identified and observed QRS index (QI), as an expression of electrical remodeling after CRT, and its relation with anatomic reverse remodeling, e…
