BackgroundSigmoid Ventricular Septum (SVS) is a type of hypertrophic cardiomyopathy characterized by a reduced angle between the basal interventricular septum and the ascending aorta, and SVS can lead to dynamic Left Ventricular Outflow Tract obstruction (LVOTO) during hypercontractile states.

BackgroundAbnormal substrate on invasive electroanatomic mapping (EAM) correlates with areas of myocardial thinning and fibrofatty replacement in Arrhythmogenic Cardiomyopathy (ACM). Transthoracic echocardiogram revealed normal biventricular function and dimension. Twelve-lead ECG showed diffuse low-voltage QRS complexes.

Hypertrophic cardiomyopathy is a genetic disorder with a guarded prognosis which occurs in about 1:500 individuals. The most common symptom of hypertrophic cardiomyopathy is dyspnoea which occurs in 90% of cases and is due to elevated left ventricular diastolic pressures as a consequence of the diastolic dysfunction.

After three unsuccessful cardioversions and refractory episodes despite Dronedarone therapy, he was scheduled for an ablation. A pre-procedural transesophageal echocardiogram showed a left ventricular (LV) ejection fraction of 55%, mild concentric LV hypertrophy, and mild left atrial enlargement. He was loaded with amiodarone.

The patient was found to have a "concealed" posteroseptal pathway (WPW without delta waves) confirmed to have SVT at EP study and was ablated. Here is the Electrophysilogist's note: "Only 1 pathway attachment could be ablated, the second one deep within the CS could not be ablated with high power. The echo was normal.

Whenever I see PVCs with the morphology and axis seen in todays case I always look for signs of AC ( Arrhythmogenic Cardiomyopathy ). Arrhythmogenic cardiomyopathy often manifests with PVCs from the RV. The ECG in Figure-1 however, shows no signs of arrhythmogenic cardiomyopathy.
