Mechanism and location of atrial flutter in transplanted hearts: observations during transient entrainment from distant sites.
This study was designed to elucidate the location and mechanism of typical atrial flutter in the transplanted heart. ⋯ Atrial flutter in transplanted hearts may best be explained by macroreentry around the tricuspid ring. In non-transplanted hearts a different structure (perhaps the CT?) may be the basis for atrial flutter at the lateral wall.

Clinical TrialPrimary pulmonary hypertension: improved long-term effects and survival with continuous intravenous epoprostenol infusion.
This study sought to determine the long-term effects of continuous infusion of epoprostenol (epo) therapy on survival and pulmonary artery pressure in patients with primary pulmonary hypertension (PPH). ⋯ Patients receiving continuous infusion of epo for treatment of PPH experience a decrease in pulmonary artery pressure. Long-term follow-up of this single-center patient group demonstrated improved long-term survival during epo therapy compared with that in historical control subjects and confirms predicted improved outcomes based on shorter follow-up periods.

Anomalous origin of left coronary artery from pulmonary artery: recovery of left ventricular function after dual coronary repair.
We reviewed our institutional experience with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) after dual coronary repair to assess preoperative variables predictive of outcome, the time course for postoperative recovery of cardiac function, the short- and long-term complications and our experience with left ventricular assist devices (LVAD) in these patients. ⋯ The degree of preoperative MR was predictive of outcome, whereas the severity of preoperative cardiac dysfunction and ventricular dilation were not. Mild and moderate MR tended to improve without mitral valvuloplasty. Complete recovery from myocardial dysfunction is expected after dual coronary repair of ALCAPA.
