The effect of distal pulmonary obstruction or elevated atrial pressures on pulmonary flow and pulmonary vascular disease: a mathematical flow circuit analogy model-based analysis.

Background: Late presentation of large left to right shunts is a major problem in developing countries and evaluating the operability is a challenge during preoperative evaluation. The factors that determine the development and progression of the pulmonary vascular disease are still largely unknown, though there is evidence to show that increased pulmonary flow is the main contributing factor. We have found cases of operability despite late presentation of ventricular septal defect (VSD).

Homemade Salvage Setup for a Catastrophic Heater/Cooler Failure on Cardiopulmonary Bypass.

Perfusion-related problems are still reported at incidence, varying from .72 to 2.86%, and add to the morbidity and mortality of cardiac surgery.

Anomalous left pulmonary artery: rare case, uncertain embryology and off-pump approach.

Left pulmonary artery from descending aorta, left-sided arch and patent ductus arteriosus is a rare congenital anomaly. Only one such case has been reported before, which was repaired in the neonatal period and the authors suggested that current theories of embryology failed to explain such a combination. Early and often bilateral pulmonary vascular disease is common with such defects.

Sinus Node Dysfunction After Extracardiac Conduit and Lateral Tunnel Fontan Operation: The Importance of the Type of Prior Superior Cavopulmonary Anastomosis.

This review summarizes the influence of the type of prior superior cavopulmonary anastomosis in the studies that report a difference in the occurrence of sinus node dysfunction among extracardiac conduit Fontan and lateral tunnel Fontan operations along with clinical implications.

Temporary clamping of branch pulmonary artery for pulmonary hemorrhage after endarterectomy.

A 49-year-old man underwent pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension. A massive pulmonary hemorrhage developed, which was identified to be from the right lower lobe, when weaning off cardiopulmonary bypass was attempted. He was managed by temporary overnight clamping of the right pulmonary artery, after the upper lobe branch.
