Anomalous left coronary artery originating from the pulmonary artery postoperative follow-up and its prognosis / 中华胸心血管外科杂志

ABSTRACT

Objective To evaluate it' s prognosis according to the follow-up statistics of coronary reimplantation of anomalous left coronary artery originating from the pulmonary artery (ALCAPA).Methods Analyze the preoperative,peri-operative and postoperative data of 20 ALCAPA patients having undergone coronary artery reimplantation.Results After coronary reimplantation,patient' s cardiothoracic ratio was obviously decreased,the degree of myocardial ischemia was improved according to electrocardiogram,the left ventricular ejection fraction and fractional shortening showed a trend of rise,mostof the patients recover in 6 months to 1 year after coronary artery reimplantation.Left ventricular end-diastolic volume index over time gradually returned to normal,mitral regurgitation gradually.improved.Conclusion ALCAPA is rare and fatal,therefore it should be diagnosed and treated as early as possible.It is also significant to avoid missed diagnosis and misdiagnosis.After coronary reimplantation,cardiac function can be gradually restored with low mortality and good prognosis result.The left ventricularejection fraction of most patients recovers to the normal standard in six months to one year' s time.
