To compare transcatheter device versus surgical closure of ventricular septal defects (VSDs).
A clinical decision analysis was performed using standard gamble interviews.
Device was initially preferred in 39 respondents (89%) and surgery in 5 (11%). The inherent difference in value between a perfect surgery and a perfect device (disutility of surgery) was equal to a mean risk of death of (1.2 +/- 2.2)%. Final values from decision analysis were initially equivalent. Values adjusted for estimated mortality, however, favored device (mean: 0.979 +/- 0.032) versus surgery (mean: 0.971 +/- 0.032), P = 0.052. When values were further adjusted for disutilities, device was significantly preferred (0.978 +/- 0.032) versus surgery (0.961 +/- 0.044), P < 0.005. Surgery would be preferred if the probability of major complications decreased below 5% or minor complications below 6%.
When outcomes and their values are considered in a systematic manner, transcatheter device closure of suitable VSDs is favored over surgical repair.
比较经导管装置与手术闭合室间隔缺损(VSD)的效果。
采用标准博弈访谈进行临床决策分析。
39名受访者(89%)最初倾向于使用装置,5名(11%)倾向于手术。完美手术与完美装置之间的固有价值差异(手术的负效用)相当于平均死亡风险为(1.2±2.2)%。决策分析的最终价值最初是相等的。然而,根据估计死亡率调整后的价值,装置(均值:0.979±0.032)优于手术(均值:0.971±0.032),P = 0.052。当根据负效用进一步调整价值时,装置(0.978±0.032)明显优于手术(0.961±0.044),P < 0.005。如果主要并发症的概率降至5%以下或次要并发症降至6%以下,则倾向于选择手术。
当以系统的方式考虑结果及其价值时,对于合适的室间隔缺损,经导管装置闭合优于手术修复。
