| E.1 Medical condition or disease under investigation |
| E.1.1 | Medical condition(s) being investigated |
|
| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| Does pre-operative administration of Sildenafil (Viagra, Pfizer) reduce the lung injury associated with cardiopulmonary bypass in children undergoing corrective surgical repair of congenital heart disease? |
|
| E.2.2 | Secondary objectives of the trial |
To further delineate the mechanism(s) of action of Sildenafil in this setting. Specifically, does pre-operative Sildenafil: − reduce post-operative pulmonary vascular resistance index? − improve post-operative oxygenation? − affect the systemic inflammatory response to cardiopulmonary bypass?

|
| E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
| E.3 | Principal inclusion criteria |
Inclusion criteria - pediatric patients undergoing open heart surgery utilising cardiopulmonary bypass to correct acyanotic congenital heart disease - age >3 months - parents that show a good understanding of their child's condition and are happy for their child to participate in the study
|
|
| E.4 | Principal exclusion criteria |
Exclusion criteria - patients with known organ dysfunction prior to surgery (pulmonary, renal or hepatic) - communication barriers resulting in poor basic comprehension of the proposed study (e.g. language barrier) - patients with cyanotic heart disease -patients undergoing heart surgery without the use of cardiopulmonary bypass - patients who do not tolerate oral Sildenafil (e.g. Vomiting) or whose surgery is subsequently cancelled
|
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
| The efficacy of pre-operative Sildenafil given to children undergoing corrective heart surgery for congenital heart disease in reducing PVRI, the systemic inflammatory response to CPB and improving oxygenation post-operatively. |
