Arrhythmogenic cardiomyopathy (AC) is an inherited heart disease characterized by fibro-fatty changes of either ventricles in isolation or in combination. AC may present with ventricular tachycardia (VT), usually with a left bundle branch block (LBBB) morphology (although VT with right bundle branch block morphology may also be encountered). Diagnosis is multi-parametric and cardiovascular magnetic resonance (CMR) holds a key role in showing the typical tissue abnormalities of the ventricles. We report the case of a patient presenting with LBBB VT with multi-modality imaging findings consistent with AC with biventricular involvement and right ventricular (RV) thrombosis. The patient was treated with antiarrhythmics, heart failure therapy, and implantable cardioverter-defibrillator implantation. RV thrombus was treated with new oral anticoagulants.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a hereditary infiltrative cardiomyopathy characterized by fibrofatty replacement of the right ventricular myocardium, which may extend to the left ventricle in the advanced stages. Clinically, the condition is commonly associated with right ventricular dilation, malignant arrhythmias, and an increased risk of sudden cardiac death. In this study, we successfully established induced pluripotent stem cell (iPSC) lines from peripheral blood mononuclear cells of ARVC patients carrying a heterozygous LMNA gene mutation (c.

Background: Cardiac sarcoidosis (CS) usually affects the left ventricle and presents with nonspecific features like conduction abnormalities and ventricular arrhythmias. However, right ventricle (RV)-dominant involvement has been increasingly reported, making diagnosis difficult.
Case Summary: A 55-year-old man presented with palpitations.

Background MRI-derived arrhythmogenic substrate, including late gadolinium enhancement (LGE) and extracellular volume fraction (ECV), is indicative of sudden cardiac death (SCD) risk in nonischemic dilated cardiomyopathy (DCM). The relative prognostic value of LGE and ECV remains unclear. Purpose To evaluate the performance of LGE and T1 mapping in predicting SCD in patients with DCM and to explore clinical implementation.

An electrical storm (ES) represents one of cardiology's most formidable and life-threatening crises, marked by relentless ventricular arrhythmias within a 24-hour period. While stimulant cardiotoxicity is an escalating concern, the devastating role of methamphetamine in triggering refractory ES and its deleterious outcomes in advanced cardiomyopathy, particularly within the critical care setting, remains profoundly underreported and poorly understood. We present the urgent case of a 44-year-old male with end-stage dilated cardiomyopathy and chronic, heavy methamphetamine abuse, who spiraled into incessant ventricular tachycardia (VT) storm following acute methamphetamine use.
