Paediatric and adult congenital cardiology education and training in Europe.

BACKGROUND: Limited data exist on training of European paediatric and adult congenital cardiologists. METHODS: A structured and approved questionnaire was circulated to national delegates of Association for European Paediatric and Congenital Cardiology in 33 European countries. RESULTS: Delegates from 30 countries (91%) responded. Paediatric cardiology was not recognised as a distinct speciality by the respective ministry of Health in seven countries (23%). Twenty countries (67%) have formally accredited paediatric cardiology training programmes, seven (23%) have substantial informal (not accredited or certified) training, and three (10%) have very limited or no programme. Twenty-two countries have a curriculum. Twelve countries have a national training director. There was one paediatric cardiology centre per 2.66 million population (range 0.87-9.64 million), one cardiac surgical centre per 4.73 million population (range 1.63-10.72 million), and one training centre per 4.29 million population (range 1.63-10.72 million population). The median number of paediatric cardiology fellows per training programme was 4 (range 1-17), and duration of training was 3 years (range 2-5 years). An exit examination in paediatric cardiology was conducted in 16 countries (53%) and certification provided by 20 countries (67%). Paediatric cardiologist number is affected by gross domestic product (R2 = 0.41). CONCLUSION: Training varies markedly across European countries. Although formal fellowship programmes exist in many countries, several countries have informal training or no training. Only a minority of countries provide both exit examination and certification. Harmonisation of training and standardisation of exit examination and certification could reduce variation in training thereby promoting high-quality care by European congenital cardiologists.

Moderate versus deep hypothermia for the arterial switch operation--experience with 100 consecutive patients.

OBJECTIVES: To evaluate the impact of moderate versus deep perioperative hypothermia on postoperative morbidity in patients receiving the arterial switch operation (ASO). METHODS: One hundred consecutive patients received the ASO from 9/98 to 4/06 using temperature-corrected full-flow moderate (M>24 degrees C, n=51) or deep hypothermic cardiopulmonary bypass (CPB) (D <20 degrees C, n=49). Complex TGA morphology was present in 33 patients (M: 27.4%, D: 38.8%, n.s.). Median age was 9 days (M) versus 10 days (D) and body weight was 3.5+/-0.7 kg (M) versus 3.6+/-0.9 kg (D) (both p=n.s.). Follow-up was 3.7+/-2.1 years. RESULTS: Lowest perioperative rectal temperature was 25.3+/-1.1 degrees C (M) versus 19.0+/-0.8 degrees C (D), p<0.001. Intraoperative blood transfusion (M: 231+/-47 ml, D: 252+/-112 ml, p=0.04) and postoperative lactate level (M: 3.2+/-1.3 mmol/l, D: 3.8+/-2.4 mmol/l, p=0.02) were lower under moderate hypothermia. One patient (D) suffered myocardial ischemia, required ECMO support and died. All other patients were safely weaned from CPB using dopamine (M: 3.0 microg/kg min, D: 3.4 microg/kg min, n.s.) and dobutamine (M: 5.6 microg/kg min, D: 6.7 microg/kg min, p=0.048). Secondary chest closure was performed in 41% (M) versus 59% (D) (p=0.04). Patients were extubated after 89 h (M) versus 126 h (D) (p=0.03). Under moderate hypothermia ICU stay (M: 8.4+/-4.7 days, D: 12.0+/-13.8 days, p=0.03) and hospital stay (M: 12.8+/-6.8 days, D: 20.7+/-15.5 days, p=0.001) were shorter. Five-year freedom from reoperation was 97.0% for simple and 85.2% for complex TGA with RVOT reconstruction in 4/6 patients. CONCLUSIONS: The ASO under full-flow moderate compared to deep hypothermia was advantageous regarding length of procedure and primary chest closure rate. Moderate hypothermia seemed to be beneficial for pulmonary recovery, length of chest tube drainage treatment and inotropic support. No worse early or long-term effects of moderate hypothermia were found.
