An occlusive Thebesian valve prevented entry into the coronary sinus ostium. Careful analysis of the patient's cardiovascular physiology and anatomy revealed the "fortuitous” presence of a persistent left superior vena cava. Cannulation of this vessel permitted percutaneous retrograde placement of a left ventricular lead into a posterolateral cardiac venous branch resulting in successful cardiac resynchronization. This unique case provides strong evidence that thorough knowledge of cardiac embryology, anatomy, and physiology plays a pivotal role in percutaneous electromechanical intervention for drug-refractory heart failure.
