Follow-up

Further Inpatient Care

  • The severity of symptoms in patients with anomalous left coronary artery from the pulmonary artery (ALCAPA) at presentation determines whether the patient is admitted to an intensive care unit (ICU) for aggressive medical management of congestive heart failure (CHF) before surgical revascularization.
  • Initial postoperative management occurs in a pediatric ICU until the patient is extubated and no longer requires intravenous inotropic support or antiarrhythmics.
  • Following surgical revascularization, postoperative care includes the use of inotropes, diuretics, and afterload reduction medication to improve cardiac output and to eliminate the preoperative symptoms of CHF.
  • Monitor continuously during the immediate postoperative period because there is a risk, although unusual, of cardiac dysrhythmia secondary to preoperative myocardial ischemia or infarction.

Further Outpatient Care

  • The clinical status of the patient, in relation to residual CHF symptoms, determines the frequency of postoperative outpatient follow-up visits.
  • Most patients do not require frequent cardiac evaluation following surgical revascularization once ventricular function and mitral valve insufficiency is dramatically improved.

Inpatient & Outpatient Medications

  • The short-term use of oral digoxin, diuretics, and ACE inhibitors is common following surgical revascularization.

Complications

  • Complications are rare. The need for future valve surgery depends on the occurrence of hemodynamic complications (eg, residual mitral valve insufficiency precipitated by permanent damage of the mitral valve architecture) following surgery.
  • Late complications related to coronary artery insufficiency are more likely to occur if revascularization was accomplished by any of the following:
    • Surgical ligation
    • Bypass grafts that may become occluded or stenotic
    • Intrapulmonary tunnel technique, which may cause supravalvar pulmonary stenosis or, less commonly, become obstructed at the surgically created aortopulmonary window
  • Inadequate growth of the coronary anastomosis is possible, although unlikely, if surgical reimplantation of the left coronary artery was performed. This occurrence is similar to the rare reports of late coronary artery problems following the arterial switch procedure for transposition of the great vessels that also requires direct coronary transfer and reimplantation.

Prognosis

  • Early diagnosis using echocardiography with color flow mapping and improvements in surgical techniques (eg, myocardial preservation) dramatically improve prognosis.

Patient Education

  • All patients should undergo formal exercise stress testing at an appropriate age as an aid in determining an appropriate exercise program.
  • Long-term physical restrictions, including restrictions of participation in competitive sports, are a direct function of whether myocardial ischemia is evident at rest or during exercise.
  • No dietary restrictions are necessary following successful surgical revascularization with subsequent clinical improvement.

Miscellaneous

Medicolegal Pitfalls

  • The most serious, yet avoidable, medicolegal complication is the mistaking of symptoms in the patient older than several months who presents with anomalous left coronary artery from the pulmonary artery (ALCAPA) as idiopathic dilated cardiomyopathy or end stage myocarditis. The initial presentation may be entirely similar but the treatments are dramatically different. The clinical and initial laboratory findings may be remarkably similar. If there is significant pulmonary artery hypertension, the diagnostic ECG findings may not be apparent.
  • A high index of suspicion is necessary to make the diagnosis of ALCAPA, since surgical treatment is extremely successful and results in an excellent long-term prognosis.

Special Concerns

  • With successful surgical revascularization and resolution of myocardial dysfunction in female patients, pregnancy and normal vaginal delivery are not contraindicated.
  • In patients with persistent myocardial dysfunction, mitral valve insufficiency, or coronary ischemia, the ability to carry a pregnancy to term varies. These patients should be considered high risk and require close observation throughout the pregnancy by both a cardiologist and a perinatologist because the increase in blood volume may be deleterious to the patient's hemodynamic status. A normal vaginal delivery may also be contraindicated in this situation.
