Left Ventricular Scars in the Anterior Region With Specific Disease Characteristics

LV Scar	Distribution	Phenotype	Red Flags		Etiologies	Further Investigation
Anterior Region	Mid-wall/Transmural	HCM	CLINICAL:	•Family history of HCM or SCD	Sarcomeric HCM	Genetic testing
			ECG:	•“Pseudo STEMI” pattern
			ECHO:	•Mitral valve abnormalities: elongated anterior leaflet/SAM
				•Apical or asymmetric LVH

HCM = hypertrophic cardiomyopathy; LVH = left ventricular hypertrophy; SAM = systolic anterior motion; SCD = sudden cardiac death; STEMI = ST-segment elevation myocardial infarction.
