OBJECTIVE The aim of this study is to report our short and mid-term results of intraoperative device closure (IODC) in large secundum atrial septal defects (ASD), to evaluate its safety and to determine the impact of 'short' rim on the results. METHODS Sixty-eight patients with an ASD underwent IODC through a right minithoracotomy. Patients were divided(More)
OBJECTIVE To construct a recombinant vector that expresses 5 shRNAs targeting on the rat ventricular myocyte Kir2.1 gene in tandem and its effect in vitro METHODS Ventricular myocytes were collected from newborn Wistar rats and cultured. Five sites targeting on the rat Kir2.1 gene were selected. Accordingly 5 pairs of oligonucleotide fragments were(More)
BACKGROUND It is infeasible to occlude a doubly committed juxtaarterial ventricular septal defect (DCVSD) percutaneously. The previous perventricular device closure technique was performed through an inferior median sternotomy approach. The purpose of this study is to evaluate the feasibility, safety and efficacy of perventricular device closure of DCVSDs(More)
BACKGROUND Device closure of a wide-spaced multi-hole PmVSD is difficult to succeed in percutaneous approach. This study is to evaluate the feasibility, safety and efficacy of perventricular device closure of wide-spaced multi-hole PmVSD using a double-device implanting technique. METHODS Sixteen patients with wide-spaced multi-hole PmVSD underwent(More)
OBJECTIVE To review the surgical treatment of supracardiac type of total anomalous pulmonary venous connection (TAPVC). METHODS Twenty-four patients with supracardiac total anomalous pulmonary venous connection underwent surgical correction from July 1995 to June 2004. There were 11 males, 13 females. The patients aged from 40 days to 35 years (mean 4.5(More)
OBJECTIVE This study aimed to assess the long-term outcome of intravascular ultrasound (IVUS) application in patients with a fractional flow reserve (FFR) of 0.75-0.80. BACKGROUND Scientifically evaluating anatomical structures is vital because structure influences both physiological function and decision-making in moderate coronary lesions, especially(More)
