A 77-year-old-woman, a known case of coronary artery disease (CAD), diabetes mellitus (DM) and hypertension developed dyspnea and oppression. She had a history of congestive heart failure, and hyponatemia. This responded well to conservative management. The coronary angiogram showed normal left main coronary artery left anterior descending (LAD) and showed the patent stent at mid LAD. The left circumflex artery (LCX) was normal. The right coronary artery showed proximal focal 30% stenosis. The left ventriculography (LVG) showed Left ventricular hypertrophy (LVH) with good contractility and function ejection fraction (EF) 75%. The tip of the catheter embedded in the left ventricular wall (A) which is proved by injection the opaque media. It filled the cardiac venules, the great cardiac veins (B) and segment of coronary sinus vein stenosis (C, D). The coronary sinus (E) is seen.
