BACKGROUND: Sudden cardiac arrest (SCA) may be the sentinel expression of a sudden cardiac death-predisposing genetic heart disease (GHD). Although shown to underlie many unexplained SCAs in the young, the contribution of GHDs to sentinel SCA has never been quantified across the age spectrum. Thus, we sought to determine the contribution of GHDs in single-center referral cohort of non-ischemic SCA survivors. METHODS AND RESULTS: Retrospective analysis of 3037 patients was used to identify all individuals who experienced a sentinel event of SCA...

BACKGROUND: Predominant cardiovascular manifestations in the spectrum of Heritable Thoracic Aortic Disease include by default aortic root aneurysms- and dissections, which may be associated with aortic valve disease. Mitral- and tricuspid valve prolapse are other commonly recognized features. Myocardial disease, characterized by heart failure and/or malignant arrhythmias has been reported in humans and in animal models harboring pathogenic variants in the Fibrillin1 gene. METHODS: Description of clinical history of three cases from one family in Ghent (Belgium) and one family in St...

We present the case of a spontaneously aborted sudden cardiac death related to an high-rate ventricular tachycardia in an healthy man with bileaflet mitral valve prolapse. An effective treatment of the patient, with complete suppression of ventricular ectopic activity, was achieved only combining medical therapy, ICD and catheter ablation, thus overcoming the limitations of each approach.

Mitral valve prolapse (MVP) is a common and benign condition. However, some anatomic forms have been recently associated with life-threatening ventricular arrhythmias and sudden cardiac death. Imaging MVP holds the promise of individualized MVP risk assessment. Noninvasive imaging techniques available today are playing an increasingly important role in the diagnosis, prognosis and monitoring of MVP. In this article, we will review the current evidence on arrhythmogenic MVP, with special focus on the utility of echocardiography and CMR for identifying benign and "malignant" forms of MVP...

Mitral valve prolapse (MVP) is a common valve abnormality in general population. Despite the general belief of a benign disorder, several articles since the 1980s report sudden cardiac death (SCD) in MVP patients, with a substantial percentage of asymptomatic young individuals. The problem is to detect those patients at increased risk and implement methods that are suitable to prevent cardiac arrest. This review investigates the correlation between MVP and SCD, the understanding of the pathophysiology, the strategies for detecting those at risk and treatment options...

Background: Outcome of Mitral Valve Prolapse (MVP) was controversial for long time. Many studies reported great differences in the incidence of cardiovascular events due, above all, to heterogeneous and small studied populations. Most of theme were also published to late '80 of the last century till early '00. Purpose: To make a contemporary survey on the incidence of cardiovascular events in a selected population of patients affected by primary MVP referred to a tertiary cardiovascular center for the medical and surgical care of valvular heart disease...

BACKGROUND: Arrhythmic mitral valve prolapse (MVP) is characterized by myxomatous leaflets and left ventricular (LV) fibrosis of papillary muscles and inferobasal wall. We searched for morphofunctional abnormalities of the mitral valve that could explain a regional mechanical myocardial stretch. METHODS AND RESULTS: Thirty-six (27 female patients; median age: 44 years) arrhythmic MVP patients with LV late gadolinium enhancement on cardiac magnetic resonance and no or trivial mitral regurgitation, and 16 (6 female patients; median age: 40 years) MVP patients without LV late gadolinium enhancement were investigated by morphofunctional cardiac magnetic resonance...

The present case report is computed tomography (CT) coronary angiographic depiction of an exceedingly rare entity-single right coronary artery arising from the right sinus of Valsalva with the absence of equivalent left coronary artery system branches and associated mitral valve prolapse. Even though a statistical rarity, it is potentially fatal and can cause myocardial ischemia, sudden cardiac death, and warrants immediate clinical attention. Further, the report reveals the decisive role of CT coronary angiogram in the diagnosis of such rare entities, in contrast to catheter angiography, which may be inconclusive...

Although it is considered to be a benign condition, previous studies have shown that a subset of patients with mitral valve prolapse (MVP) may be at risk of ventricular arrhythmia and sudden cardiac death (SCD). Previous studies have suggested that the interval between the peak and the end of the T wave (Tp-e) can be used as a marker for the transmural dispersion of repolarization. Increased Tp-e interval and Tp-e/QT ratio are associated with ventricular arrhythmias and SCD. The aim of this study was to assess alterations in ventricular repolarization by using the Tp-e interval and Tp-e/QT ratio in children with MVP and to investigate their relationships with the degree of valvular regurgitation...

The aetiology of sudden cardiac arrest can often be identified to underlying cardiac pathology. Mitral valve prolapse is a relatively common valvular pathology with symptoms manifesting with increasing severity of mitral regurgitation (MR). It is unusual for severe MR to be present without symptoms, and there is growing evidence that this subset of patients may be at increased risk of sudden cardiac arrest or death. The difficulty lies in identifying those patients at risk and applying measures that are appropriate to halting progression to cardiac arrest...

BACKGROUND: There are no ready explanations for differences in ischemic heart disease incidence between women and men under an epidemiological perspective. However, when myocardial infarction occurs, there are more likely individuals who happen to die. METHODS: This review from a more recent literature was performed for a two-fold purpose, to describe gender wise: a) the role of classical and novel factors defined to evaluate coronary artery disease (CAD) risk and mortality, aimed at assessing applicability and relevance for primary and secondary prevention; b) the differences in northern versus southern European Countries in risk factors and CAD mortality...

Sudden death of healthy young adults in the absence of any medical reason is generally categorised as autopsy-negative sudden unexplained death (SUD). Approximately 30 % of all SUD cases can be explained by lethal sequence variants in cardiac genes causing disturbed ion channel functions (channelopathies) or minimal structural heart abnormalities (cardiomyopathies). The aim of this study was to perform whole-exome sequencing (WES) in five young SUD cases in order to identify potentially disease-causing mutations with a focus on 184 genes associated with cardiac diseases or sudden death...
