Levoatriocardinal vein: a rarely recognized cause of recurrent cardiac and cerebral thromboembolic events

We describe the case of a 43-year-old patient who presented with a transient ischemic attack episode, desaturation and ventricular arrhythmias. Transesophageal echocardiography diagnosed a PFO, whilst magnetic resonance imaging revealed two small myocardial infarcts, despite normal coronaries on subsequent angiography. Echocardiography and cardiac CT revealed a LACV with bidirectional flow. The patient underwent percutaneous LACV and PFO closure, with immediate saturation increase following occlusion of the LACV. To the best of our knowledge, this is the first time a LACV is identified as the cause of recurrent thromboembolic events.

AbstractPremature ventricular complexes (PVCs) are common arrhythmias in the clinical setting. PVCs in the structurally normal heart are usually benign, but in the presence of structural heart disease (SHD), they may indicate increased risk of sudden death. High PVC burden may induce cardiomyopathy and left ventricular (LV) dysfunction or worsen underlying cardiomyopathy. Sometimes PVCs may be a marker of underlying pathophysiologic process such as myocarditis. Identification of PVC burden is important, since cardiomyopathy and LV dysfunction can reverse after catheter ablation or pharmacological suppression. This state-of...

Authors: Yuan WF, Zhao XX, Hu FB, Bai C, Tang F Abstract BACKGROUND The diagnosis of myocarditis is challenging, and the treatment is generally delayed due to misdiagnosis or missed diagnosis. Endomyocardial biopsy (EMB) is not a specific or sensitive method. A case-controlled observational study was conducted to evaluate early gadolinium enhancement (EGE) and left ventricular functional parameters on Artificial Intelligence in cine-MRI in patients with acute myocarditis. MATERIAL AND METHODS We selected 21 patients with pathologically proven acute myocarditis. We analyzed the EGE findings (total/serial number and ...

ConclusionRight SCA with congenital absence of the LCA is one of the rarest coronary artery anomalies. In a significant percentage of patients it is associated with ischemia and can be life-threatening. CCTA and MRI are the modalities of choice for diagnosis and risk stratification.ResumoIntroduçãoArtéria coronária única (ACU) sem cardiopatia congénita associada é uma entidade rara. Maioria dos casos é assintomática e achados acidentais, mas podem causar isquémia, insuficiência cardíaca congestiva e morte súbita (MS).Caso clíni...

Abstract Arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) was initially recognized as a clinical entity by Fontaine and Marcus, who evaluated a group of patients with ventricular tachyarrhythmia from a structurally impaired right ventricle (RV). Since then, there have been significant advances in the understanding of the pathophysiology, manifestation and clinical progression, and prognosis of the pathology. The identification of genetic mutations impairing cardiac desmosomes led to the inclusion of this entity in the classification of cardiomyopathies. Classically, ARVC/D is an inherited disease characte...

ConclusionsWe present a case of catecholaminergic polymorphic ventricular tachycardia associated with a novel single point mutation in the RyR2 gene, which, to the best of our knowledge, has not been described in the literature so far. Our patient experienced arrhythmic events under both resting conditions and physical activity, an uncommon finding in patients with catecholaminergic polymorphic ventricular tachycardia. This novel mutation may cause arrhythmias independent of sympathoadrenergic stimulation, but further evidence is needed to prove causality.

Authors: Muser D, Santangeli P, Selvanayagam JB, Nucifora G Abstract Ventricular Arrhythmias (VAs) may present with a wide spectrum of clinical manifestations ranging from mildly symptomatic frequent premature ventricular contractions to life-threatening events such as sustained ventricular tachycardia, ventricular fibrillation and sudden cardiac death. Myocardial scar plays a central role in the genesis and maintenance of re-entrant arrhythmias which are commonly associated with SHD such as ischemic heart disease, healed myocarditis and non-ischemic cardiomyopathies. However, the arrhythmogenic substrate may remai...

We present here a 42-year-old man with an inverted Takotsubo variant with pulmonary edema and transient accelerated idioventricular rhythm. He was initially admitted in the Emergency Department for acute and non-complicated appendicitis. Coronary angiogram showed normal coronary arteries and left ventriculography revealed a reverse variant of TTC. The patient had completely recovered. Myocarditis was ruled out by cardiac magnetic resonance imaging.

Conclusions— CMR identified a likely pathogenesis for sudden cardiac arrest in nearly half of survivors in whom coronary artery disease had been excluded. One in 3 subjects had MACE; risk doubled in those with a CMR diagnosis and some CMR parameters—late gadolinium enhancement, left ventricular ejection fraction, and especially right ventricular ejection fraction—associated with prognosis.

Authors: Matsuoka R, Muneuchi J, Nagatomo Y, Shimizu D, Okada S, Iida C, Shirouzu H, Watanabe M, Takahashi Y, Maruyama H Abstract An 11-year-old boy collapsed during morning assembly at his junior high school. The automated external defibrillator detected ventricular fibrillation and provided shock delivery. He was successfully resuscitated and reverted to sinus rhythm. Electrocardiography showed ST-T elevation in the precordial leads. Echocardiography and angiography demonstrated akinesia of the apex and mid-wall of the left ventricle with preserved contraction of the basal segments, which suggested Takotsubo card...
