The Role of Cardiovascular Magnetic Resonance in ARVC.

Curr Cardiol Rep 2021 05 7;23(6):56. Epub 2021 May 7.

Fondazione Toscana G.Monasterio, via Moruzzi 1, 56124, Pisa, Italy.

Purpose Of Review: Aim of the paper was to address all strengths and weakness of cardiac magnetic resonance (CMR) in arrhythmogenic cardiomyopathy, trying to highlight areas where further research and investigations should be carried out to fill current gaps in scientific knowledge.

Recent Findings: Arrhythmogenic cardiomyopathy represents a multifaceted clinical entity associated with arrhythmias and sudden death. Even though different diagnostic tools are available for appropriate identification and risk stratification, over the last few years cardiac magnetic resonance (CMR) has surfaced as an unmatched non-invasive imaging tool.

Erich and Hanna Klessmann Institute, Heart and Diabetes Center NRW, University Hospital of the Ruhr-University Bochum, Georgstrasse 11, 32545 Bad Oeynhausen, Germany.

About 50% of patients with arrhythmogenic cardiomyopathy (ACM) carry a pathogenic or likely pathogenic mutation in the desmosomal genes. However, there is a significant number of patients without positive familial anamnesis. Therefore, the molecular reasons for ACM in these patients are frequently unknown and a genetic contribution might be underestimated. Read More

Electroanatomic voltage mapping and characterisation imaging for "right ventricle arrhythmic syndromes" beyond the arrhythmia definition: a comprehensive review.

Int J Cardiovasc Imaging 2021 Mar 24. Epub 2021 Mar 24.

Elettrofisiologia, U.O.C Di Cardiologia, Ospedale Civile Treviso, Treviso, Italy.

Three-dimensional (3D) reconstruction by means of electroanatomic mapping (EAM) systems, allows for the understanding of the mechanism of focal or re-entrant arrhythmic circuits along with pacing techniques. However, besides this conventional use, EAM may offer helpful anatomical and functional information. Data regarding electromechanical scar detection in ischaemic (and nonischaemic) cardiomyopathy are mostly consolidated, while emerging results are becoming available in contexts such as arrhythmogenic right ventricular dysplasia (ARVC/D) definition and Brugada syndrome.

Left Ventricular Dysfunction in Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC): Can We Separate ARVC From Other Arrhythmogenic Cardiomyopathies?

J Am Heart Assoc 2020 12 21;9(23):e018866. Epub 2020 Nov 21.

Cardiovascular Division Department of Medicine University of Pennsylvania Philadelphia PA.

Arrhythmogenic right ventricular cardiomyopathy was first described as a right ventricular disease that is an important cause of death in young adults. However, with the advent of advanced imaging, arrhythmogenic right ventricular cardiomyopathy has been found to commonly have biventricular involvement, and a small portion of patients have left ventricular-dominant forms. On the other hand, a number of primarily left ventricular disease such as sarcoid and myocarditis can be arrhythmogenic and have right ventricular involvement. Read More

Characteristics of Patients With Arrhythmogenic Left Ventricular Cardiomyopathy: Combining Genetic and Histopathologic Findings.

Circ Arrhythm Electrophysiol 2020 12 15;13(12):e009005. Epub 2020 Dec 15.

Heart Rhythm Center (M.C., A.G., R.S., V.C., M.B., G.V., C.T.), Centro Cardiologico Monzino IRCCS, Milano.

Background: Arrhythmogenic left ventricular cardiomyopathy (ALVC) is an under-characterized phenotype of arrhythmogenic cardiomyopathy involving the LV ab initio. ALVC was not included in the 2010 International Task Force Criteria for arrhythmogenic right ventricular cardiomyopathy diagnosis and data regarding this phenotype are scarce.

Methods: Clinical characteristics were reported from all consecutive patients diagnosed with ALVC, defined as a LV isolated late gadolinium enhancement and fibro-fatty replacement at cardiac magnetic resonance plus genetic variants associated with arrhythmogenic right ventricular cardiomyopathy and of an endomyocardial biopsy showing fibro-fatty replacement complying with the 2010 International Task Force Criteria in the LV.

Tale of fat and fib - cardiac lipoma managed with radiofrequency ablation: A case report.

World J Cardiol 2020 Jun;12(6):285-290

Department of Cardiology, Saint Vincent Hospital, Worcester, MA 01604, United States.

Background: Cardiac lipoma and lipomatous hypertrophy of interatrial septum (LHIS) are very rare disorders with distinct pathological features. While cardiac lipoma is a well-circumscribed encapsulated tumor of mature adipocytes, LHIS is due to entrapment of fat cells in the interatrial septum during embryogenesis. Although a biopsy is the definitive diagnostic test, these disorders can be differentiated by a cardiac magnetic resonance imaging (MRI). Read More

A case of arrhythmogenic right ventricular cardiomyopathy with right ventricle thrombus: A case report.

Med J Malaysia 2020 07;75(4):452-454

Hospital Sultanah Aminah, Department of General Surgery, Johor, Malaysia.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare inherited cardiomyopathy characterised by right ventricular dysfunction, ventricular arrhythmias and increased risk of sudden cardiac death. Due to the replacement of myocardium with fibro-fatty and fibrous tissue, patients with ARVC are prone to develop ventricular tachycardia. Histologically, it is often reported as the 'triangle of dysplasia' involving the inflow tract, outflow tract and apex of the right ventricle. Read More

Congenital heart disease combined with Arrhythmogenic Right Ventricular Cardiomyopathy: A CARE compliant case report and literature review.

Medicine (Baltimore) 2020 Jun;99(25):e20279

Department of Cardiology, The Second Xiangya Hospital, Central South University, Changsha, Hunan Province, China.

Rationale: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a hereditary cardiomyopathy disease discovered in 1994. Though there are advances in diagnosis of arrhythmogenic right ventricular cardiomyopathy, early diagnosis is still difficult especially when it is combined with other diseases with similar pathophysiologic changes, such as left to right shunt congenital heart disease (CHD). In this paper, we reported a case of CHD combined with ARVC. Read More

Diagnosis of arrhythmogenic cardiomyopathy: The Padua criteria.

Int J Cardiol 2020 11 16;319:106-114. Epub 2020 Jun 16.

Department of Cardiac, Thoracic and Vascular Sciences and Public Health, University of Padova, Italy.

The original designation of "Arrhythmogenic right ventricular (dysplasia/) cardiomyopathy"(ARVC) was used by the scientists who first discovered the disease, in the pre-genetic and pre-cardiac magnetic resonance era, to describe a new heart muscle disease predominantly affecting the right ventricle, whose cardinal clinical manifestation was the occurrence of malignant ventricular arrhythmias. Subsequently, autopsy investigations, genotype-phenotype correlations studies and the increasing use of contrast-enhancement cardiac magnetic resonance showed that the fibro-fatty replacement of the myocardium represents the distinctive phenotypic feature of the disease that affects the myocardium of both ventricles, with left ventricular involvement which may parallel or exceed the severity of right ventricular involvement. This has led to the new designation of "Arrhythmogenic Cardiomyopathy" (ACM), that represents the evolution of the original term of ARVC. Read More

Automatic Detection of Slow Conducting Channels during Substrate Ablation of Scar-Related Ventricular Arrhythmias.

J Interv Cardiol 2020 29;2020:4386841. Epub 2020 May 29.

Teknon Medical Center, Barcelona, Spain.

Background: Voltage mapping allows identifying the arrhythmogenic substrate during scar-related ventricular arrhythmia (VA) ablation procedures. Slow conducting channels (SCCs), defined by the presence of electrogram (EGM) signals with delayed components (EGM-DC), are responsible for sustaining VAs and constitute potential ablation targets. However, voltage mapping, as it is currently performed, is time-consuming, requiring a manual analysis of all EGMs to detect SCCs, and its accuracy is limited by electric far-field. Read More
