[The anatomy features and surgical significance of the pulmonary circuits of pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries].

Objectives: To analyze the anatomy features of the pulmonary circuits in the patients with pulmonary atresia (PA) with ventricular septal defect (VSD) and major aortopulmonary collateral arteries (MAPCA), and discuss the clinical significance.

Methods: From April 2002 to June 2010, the anatomy features of pulmonary circuits in 33 patients with PA/VSD/MAPCA were examined and analyzed. There were 21 male and 12 female patients.

[Clinical analysis of surgical procedures and outcomes for corrected transposition of great arteries with heart anomaly].

Objective: To determine the outcome of anatomically corrective repair and traditional repair of corrected transposition of great arteries (c-TGA) with heart anomaly.

Methods: From April 2002 to December 2006, nineteen patients including fourteen male and five female with c-TGA, underwent operations, age ranged from 2 to 22 years old and weight ranged from 10 to 48 kg. Fifteen of them received anatomically corrective repair and the other four received traditional repair.

[Study of cardiopulmonary adaptation during exercise in patients after extracardiac conduit total cavopulmonary connection].

Objective: To study cardiopulmonary physiology during exercise in patients after extracardiac total cavopulmonary connection (ECTCPC).

Methods: Twenty-six patients were studied after ECTCPC by exercise testing with bicycle treadmill protocol. Heart rate (HR), blood pressure (BP), respiratory frequency (RF) and pulse oxygen saturation (SpO(2)) were measured continuously; twenty-six patients suffered from Fallot 4 underwent biventricular repair were also studied as control group.

[Clinical analysis on surgical treatment of single atrium].

Objective: To summarize the experience of surgical treatment of single atrium.

Methods: From August 1984 to August 2004, there were 33 patients with single atrium in our study. Plastic surgery for mitral valves were performed for 30 cases with mitral insufficiency.

[The effects of inhaled nitric oxide on pulmonary vascular resistance in patients after total cavopulmonary connection].

Objective: To study the effects of inhaled nitric oxide (NO) on pulmonary vascular resistance in patients after total cavopulmonary connection (TCPC).

Methods: Fifty-two patients after TCPC were evaluated, of them 24 patients were administered with inhaled nitric oxide in the early postoperative period. The cardiac index (CI) and pulmonary vascular resistance (PVR) were compared before and after inhaled NO.

[Surgical treatment of secundum atrial septal defects in adults over 30 years old].

Objective: To summarize the experience of surgical treatment of secundum atrial septal defects in adults over 30 years old.

Methods: There were 469 patients with secundum atrial septal defects in our study (male 144, female 325; ages 30-68, mean 38.6 years old).

Total cavopulmonary connection with extraatrial tunnel.

Between April 1997 and February 2000, total cavopulmonary connection with an extraatrial tunnel was used to treat 9 cases of complicated congenital heart disease: single ventricle (4), double-outlet right ventricle (3), mitral atresia (1), and tricuspid atresia (1). There was no mortality. One patient developed bacterial endocarditis and required reoperation after 52 days to replace the tunnel.
