Strategies for drug-eluting stent treatment of bifurcation coronary artery disease in the United States: insights from the e-Cypher S.T.L.L.R.trial.

Objectives: Our goal is to report the first large multicenter data for percutaneous coronary intervention (PCI) of bifurcation disease with drug-eluting stents (DES) in the United States.

Background: Bifurcation PCI remains a challenge to this date. There are limited data on outcomes of patients treated with bifurcation DES implantation, particularly in the United States.

Two-dimensional and Doppler transesophageal echocardiographic delineation and flow characterization of anomalous coronary arteries in adults.

Objectives: The purpose of this study was to examine the use of transesophageal echocardiography (TEE) in the identification and flow characterization of congenital coronary anomalies.

Background: Congenital coronary anomalies in adults are rare but may cause serious cardiac complications. The use of TEE in evaluation of this entity has not been well defined.
