Intravenous anesthesia is commonly used in pediatric cardiac catheterization. Objectives: (1) Define the efficiency of this method administered for pediatric cardiac cathterization; (2) Evaluate, analysis some anesthetic complications occurred during and after the producedure. Methods: Either Ketamin or Propofol was used for the induction. Anesthesia was maintained by Propofol infusion. 41 patients who underwent cardiac catheterization were included into the study. Heart rate, SpO2, respiratory rate of patient and the quality as well as the complications of anesthesia were evaluated. Results: The rate of good induction, good maintenance and good recovery were 95.2%, 97.6% and 100%, respectively. 82.3% of patients had a recovery time around 15 minutes. The complications of anesthesia were documented: apnea and transient drop of SpO2 occurred in the induction (4.8%), severe respiratory distress (2.4%), increasing secretor sputum (4.8%). Conclusions: Intravenous anesthesia has maitained the efficiency of sedation for pediatric cardiac catheterization.

OBJECTIVETo develop an inflow cannula of left ventricular assist implanted by blood vessel.

METHODSThe maximum inflow and properties against folding of 8 sorts of cannulae were measured in mimic extracorporeal circulation appliances and canines.

RESULTSThe maximum flow of the cannula increased, as the inner diameter became greater (P < 0.01) compared with each group. The maximum flow rate was (1.82 +/- 0.03) L/min, (2.44 +/- 0.03) L/min, (3.02 +/- 0.04) L/min, (3.31 +/- 0.03) L/min respectively for polyvinyl cannulae with wall thickness of 0.5 mm (PV 0.5 cannula) and inner diameter of 3 mm, 4 mm, 5 mm, 6 mm; (1.83 +/- 0.03) L/min, (3.07 +/- 0.04) L/min respectively for the polyvinyl chloride cannula with wall thickness of 1.0 mm imbedded by spring wire (PVCSW 1.0) and inner diameter of 3 mm and 5 mm; (1.82 +/- 0.02) L/min, 1.84 +/- 0.02 L/min for strengthened polyvinyl cannula with wall thickness of 0.8 mm (SPV 0.8) and inner diameter of 3 mm and polyvinyl cannula with wall thickness of 1.0 mm (PV 1.0 cannula) of inner diameter of 3 mm. There was no remarked statistical difference in vitro maximum flow among the four cannulae of 3 mm inner diameter in vitro. PVCSW 1.0 was showed the best antifolding property, PV 1.0 cannula good and SPV 0.8 and PV 0.5 unsatisfactory in properties against fold. There was no significant statistical difference between in vivo and in vitro maximum flow for PVCSW 1.0 and PV 1.0 cannulae of 3 mm inner diameter. But for SPV 0.8 and PV 0.5 cannulae of 3 mm inner diameter, there was a significant difference between in vivo and in vitro.

CONCLUSIONSPV 0.5 cannula and SPV 0.8 cannula are not suitable to clinical use. PV 1.0 cannula can be used in clinics. PVCSW 1.0 cannula is fully qualified for inflow conduit of left ventricular assist in surgery.

Percutaneous device occlusion of secundum atrial septal defect (ASD) has become an accepted alternative to surgical repair. A variety of devices have been used successfully. However, all of them have limitations. We report our experience with two devices used to close multiple ASDs.

PURPOSE: To identify the essential characteristics of pain which nurse have to obtain for patients with chest pain, 92 patients who were admitted in medical units to take intensive tests for heart disease were investigated cross-sectionally. METHOD: Duration, severity, stress, anxiety, perceived severity, number of painful area, number of accompanying symptoms, triggering activity, and pattern were included as the characteristics of pain. Ejection fraction of left ventricle and number of involved area detected by ultrasonography and number of diseased coronary artery detected by cardiac catheterization were assessed as the variables of heart disease extent. RESULT: Severity of pain was found to be correlated with all three variables of heart disease extent. Perceived severity and number of accompanying symptoms were correlated with two of them. Anxiety, number of painful area and pattern were related with the number of involved area. CONCLUSION: Pain severity reported by patients is found to be the most important variable to be obtained from patient. Variables such as perceived severity. number of accompanying symptoms, anxiety, number of painful area and pattern also have to be carefully assessed to anticipate the extent of heart disease.

BACKGROUND AND OBJECTIVES: Vascular stenosis after surgical repair frequently occurs in congenital heart disease. Although conventional balloon dilation is a useful option for stenotic lesions, restenosis may occur. Consequently, balloon expandable stents have been used; however, there are a limited number of balloon expandable stents in our country. Here, we report the early and intermediate-term outcomes of self-expandable stents in vascular stenosis of moderate to large-sized vessels in congenital heart disease. METHODS: Twelve self-expandable stents were implanted in 9 patients between February 2012 and January 2019. The median age and weight were 12 years (range, 4–39 years) and 38 kg (range, 19–69 kg), respectively. The patients were followed-up for a median duration of 43 months (range, 1–83 months) after stent implantation. RESULTS: Nine self-expandable stents were implanted in the pulmonary artery, 2 stents in the right ventricle to the pulmonary artery conduit, and 1 stent in the coarctation. The narrowest diameter of the stented vessel increased from 5.7±3.2 mm to 12.6±3.4 mm (p<0.05). The mean pressure gradient across the stenotic lesion decreased from 23.0±28.2 mmHg to 3.2±3.6 mmHg (p<0.05). Distal migration of the stent occurred in 1 patient, and significant neointimal ingrowth was noted in 1 patient. CONCLUSIONS: The self-expandable stent may be a useful option to relieve vascular stenosis in moderate to large-sized vessels with acceptable intermediate-term outcomes.

Perforation of the interventricular septum complicating acute myocardial infarction is uncommon. The condition was first described anatomically by Latham in 1845 and the first antemortem diagnosis was made by Brunn in 1923. In both cases, bedside catheterization utilizing a flow directed catheter detected a step up of O2 saturation at the ventricular level, compatible with ventricular septal defect, and two dimensional echocardiogram allowed direct visualization and localization of the postmyocardial infarction VSD. Finally cineventriculogram confirmed them.
