1. Serial Intravascular Ultrasound Analysis of the Main and Side Branches in Bifurcation Lesions Treated With the T-Stenting Technique

Hahn et al.

They did IVUS after PCI of bifurcation lesions immediately after the procedure and at 9 months. The PCIs used DES and employed the T-stenting with minimal protrusion technique. They found that narrowing was more common at the side branch ostium than at the main branch ostium. It was thought to be due to inadequate dilation of side branch ostium at stenting and due to neointimal hyperplasia.

  1. Longer-Term Follow-Up of Patients Recruited to the REACT Trial

Carver et al.

Long term follow up of patients who had undergone rescue angioplasty in the REACT trial showed that there is mortality reduction compared to conservative therapy or repeat thrombolysis.

  1. Giant T–U Waves Precede Torsades de Pointes in Long QT Syndrome: A Systematic Electrocardiographic Analysis in Patients With Acquired and Congenital QT Prolongation

Kirchhof et al

This study found that in LQTS, torsades de pointes is initiated by abnormal, giant T-U waves. This supports the notion that torsades de pointes is triggered in LQTS by early after depolarizations.

  1. Long-Term Prognostic Value of 13N-Ammonia Myocardial Perfusion Positron Emission Tomography: Added Value of Coronary Flow Reserve

Herzog et al.

Abnormal coronary perfusion and coronary flow reserve, picked up by 13 N ammonia PET, predicted, in the long term, adverse cardiac events and mortality.

  1. The Effect of Age, Diagnosis, and Previous Surgery in Children and Adults Undergoing Heart Transplantation for Congenital Heart Disease

Lamour et al

They studied the long term survival in children who underwent heart transplant for congenital heart diseases. Early mortality was more than those who underwent heart transplant for cardiomyopathy. But once the early period is survived, survival is the same as for other groups. Early mortality is more with older patient age, older donor age and previous Fontan. Constant phase mortality was more with younger patient age, previous classical Glenn, higher transpulmonary gradient and cytomegalovirus mismatch.

  1. Fundamental Differences in Electrophysiologic and Electroanatomic Substrate Between Ischemic Cardiomyopathy Patients With and Without Clinical Ventricular Tachycardia

Haqqani et al

They did electrophysiological studies in ischemic cardiomyopathy patients with and without sustained monomorphic VT. It was found that those who had VT had smaller zones with low voltage, lower density of scar related ECG and fewer fast conducting channels.
