Objective To explore the application of ultrasound- guide modified Seldinger technique for upper arm PICC insertion in infant patients. Methods Use the ultrasound-guide modified Seldinger technique to inserted PICC for 27 infant patients. Results All 27 cases were inserted successfully, success rate of the one puncture reached 92.6%. Conclusions By adequate preparation for infants, effective immobilization and good cooperation of operators, and combined with techniques which prevent PICC misplacement, overcome the shortcoming of bad vessel and non-compliance of infant patients, develop the advantage of ultrasound, could improve the rate of successful catheterization of upper arm PICC insertion in infant patients, and protect the vessels.

Objective To analyze the value of plane QRS-T angle on prediction of malignant ventricular arrhythmia (MVA) occurred after emergency percutaneous coronary intervention (PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). Methods The clinical data of 418 patients with STEMI who underwent PCI within 12 h of symptom onset were retrospectively analyzed, and the patients were divided into plane QRS-T angle ≤ 90° group (324 cases) and plane QRS-T angle>90° group (94 cases) according to the plane QRS-T angle after PCI. The clinical data were compared between 2 groups. Results Compared with patients in plane QRS-T angle ≤ 90° group, patients in plane QRS-T angle > 90° group was older: (67.4 ± 11.8) years vs. (63.6 ± 12.0) years, QTc interval was longer: (438.60 ± 34.97) ms vs. (425.24 ± 25.49) ms, rate of left ventricular ejection fraction (LVEF) <45% was higher: 57.4% (54/94) vs. 35.8% (116/324), rate of using of beta-blockers was less: 74.5% (70/94) vs. 84.9% (275/324), but the incidences of hypertension and MVA were higher:79.8%(75/94) vs. 64.5%(209/324) and 10.6%(10/94) vs. 1.2%(4/324), and there were statistical differences (P<0.01 or<0.05). Logistic regression analysis showed that plane QRS-T angle >90° was an independent risk factor of MVA after PCI in STEMI patients (OR = 9.640, P =0.001), and using of beta-blockers was a protective factor (OR = 0.266, P = 0.028). Conclusions Plane QRS-T angle>90° is an independent risk factor of MVA after PCI in STEMI patients, while the use of beta-blockers is a protective factor. Paients with STEMI after PCI should be alert to the occurrence of MVA in the condition of plane QRS-T angle>90° and not taking beta-blockers.

Objective:
Exploring the feasibility of the 2014 European Society of Cardiology(ESC)guideline′s risk prediction model for sudden cardiac death in hypertrophic cardiomyopathy (HCM Risk-SCD) in Chinese patients.
Methods:
The study population consisted of a consecutive cohort of 172 Chinese patients with HCM without prior sudden cardiac death (SCD) event who were in patients in Nanjing Drum Tower Hospital from December 2010 to October 2015.The endpoint event was a composite of SCD and appropriate implantable cardioverter-defibrillator (ICD) therapy.Clinical data were collected to calculate the 5-year SCD risk using the HCM Risk-SCD formula and to observe the actual risk during the follow-up.Receiver operating characteristic curves (ROC) and the area under curve (AUC) were calculated for the HCM Risk-SCD and risk stratification methods of the 2011 American Heart Association (AHA) guideline.
Results:
During follow-up of (2.69±1.36) years, five patients achieved the endpoint event.The predicated rate of SCD event using HCM Risk-SCD was (2.36±1.73)%, (1.93±0.78)%, (5.18±0.65)%, (8.77±2.38)% for all patients, low-risk group, medium-risk group and high-risk group respectively.However, the actual rate of SCD event was 2.91%, 1.27%, 25.00% and 14.29%, respectively.The AUC of 2014 ESC guideline and 2011 AHA guidelinewas 0.93(95%
