11/642. Aortoventriculoplasty after a prior posterior root enlargement (Manougian): case report.

    A patient with congenital bicuspid aortic stenosis had an open commissurotomy followed 3 years later by a Manougian's operation along with an aortic valve replacement. Nine years later, due to residual aortic stenosis, a Konno's anterior root enlarging procedure with an aortic valve replacement was successfully done. Good relief of aortic and subaortic stenosis and the absence of significant gradient across the left ventricular outflow tract led us to believe that successful and effective relief could be obtained by adding a Konno-type of enlargement to a previously performed posterior enlargement procedure.

12/642. Echocardiographic diagnosis of left ventricular outflow tract obstruction caused by an acquired subaortic membrane after mitral valve replacement.

    Although an acquired subaortic membrane has been reported as a cause of left ventricular outflow tract (LVOT) obstruction in various clinical settings, it previously has not been reported after mitral valve surgery. We describe 3 cases of acquired LVOT obstruction that resulted from development of a subaortic membrane after mitral valve replacement. This report emphasizes the role of an acquired subaortic membrane in LVOT obstruction after mitral valve replacement, the use of echocardiography in diagnosing this condition, and the importance of early intervention.

13/642. Doppler echocardiography as a predictor of pregnancy outcome in the presence of aortic stenosis: A case report.

    Aortic stenosis in pregnancy can be a life-threatening condition, but fortunately it is rare. In the modern era, careful obstetric and cardiologic monitoring, particularly through echocardiography, have improved fetal and maternal outcomes. However, a test that could predict outcome has not been available for patients with aortic stenosis who seek prepregnancy counseling. We report a case in which exercise Doppler echocardiography was used to predict cardiac function and maximal gradients in a woman with a bicuspid aortic valve who wished to become pregnant.

14/642. Surgical angioplasty of left main coronary stenosis complicating supravalvular aortic stenosis.

    We successfully treated obstruction of the main coronary artery, not aortic valve leaflet adhesion to the intimal shelf, complicating supravalvular aortic stenosis by modifying the Brom aortoplasty. An autologous pericardial patch was used to enlarge the left main coronary artery as well as the stenotic aorta. This modification allows simple and effective restoration of coronary blood flow, while maintaining the Brom procedure's merit of achieving anatomic geometry of the aortic root in such patients.

15/642. Application of successive principles of repair to correct supravalvular aortic stenosis.

    The diffuse form of supravalvular aortic stenosis may extend in the takeoff of the coronary and arch arteries. Relief of the supravalvular stenosis requires a harmonious enlargement of the sinotubular junction to maintain aortic valve competence. The technique we used in a 9-year-old boy involved patch enlargement of all affected structures. Deep hypothermic circulatory arrest and retrograde cerebral perfusion was used during repair of the aortic arch and arch arteries.

16/642. cor triatriatum sinistrum, aortic coarctation and bicuspid aortic stenosis in an adult.

    Cardiac anomalies are usually diagnosed early in life, which is particularly true for their various combinations. The diagnosis in adulthood is rare. Here we report the case of a young man with an aortic coarctation corrected at the age of 16, however the associated stenotic bicuspid aortic valve and cor triatriatum sinistrum were corrected after streptococcus viridans endocarditis 7 years later.

17/642. Congenital subaortic stenosis by accessory mitral valve tissue, recognition and management.

    Accessory mitral valve tissue as the single cause for left ventricular outflow tract obstruction is a very rare cardiac malformation in normally connected hearts. We report a case in which this condition was present as single cause for left ventricular outflow tract obstruction. The surgical technique is described and a review of the literature presented.

18/642. aortic valve stenosis with left ventricular outflow tract pressure gradient.

    A 61-year-old man was diagnosed with severe aortic valve stenosis with left ventricular outflow tract pressure gradient due to systolic anterior movement of the mitral valve and a large poststenotic dilation of the ascending aorta. He underwent successful aortic root replacement and concomitant septal myectomy.

19/642. Aortic stenosis in endogenous ochronosis.

    Endogenous ochronosis, a rare inherited disease of tyrosine metabolism, is caused by a deficiency of the enzyme, homogentisic acid oxidase, and may lead to cardiovascular involvement seen most frequently as aortic valve stenosis. We report the case of a patient with generalized ochronosis who developed cardiovascular symptoms due to aortic valve stenosis and who underwent aortic valve replacement.

20/642. Alkaptonuric aortic stenosis: a case report.

    alkaptonuria is a rare disease of phenylalanine, aromatic amino acids, and tyrosine metabolism. Because of a genetic deficiency of the enzyme homogentisic acid oxidase, an accumulation of homogentisic acid causes ochronotic pigment deposition. The most common clinical manifestations are arthropathy, urinary calculi and discoloration, cutaneous and cartilaginous pigmentation, and cardiac valvular disease. Arthropathy and aortic stenosis are the most debilitating manifestations of the disease. A case of alkaptonuric aortic stenosis is described. A 75-year-old woman with a history of alkaptonuria presented in the emergency department with complaints of progressive dyspnea. Upon examination, the patient was hypertensive, tachypneic, and tachycardic with premature ventricular contractions. She had pitting edema of the lower extremities and complaints of generalized weakness. Chest x-rays revealed congestive heart failure and pulmonary edema. diuretics were administered, and a continuous nitroglycerin infusion was initiated in the emergency department. The patient was admitted for further evaluation. The patient's respiratory status continued to decline. She was intubated endotracheally 1 day after admission. Subsequent cardiac evaluation revealed an ejection fraction of 35%, severe aortic stenosis, mild coronary artery disease, ischemic cardiomyopathy, and anteroapical akinesis. A dobutamine infusion was instituted for persistent hypotension, and renal dose dopamine was initiated for oliguric renal failure. The patient underwent an emergency operation for an aortic valve replacement with a Dacron patch 10 days after admission. cardiopulmonary bypass and mild hypothermia were used during the procedure. The patient's hemodynamic status remained tenuous throughout the procedure. Although the first attempt to wean off cardiopulmonary bypass failed, the second attempt was successful with the aid of an intra-aortic balloon pump, inotropic support, and atrioventricular pacing. These measures were maintained during transport to the surgical intensive care unit. In the intensive care unit, the patient did not have an audible blood pressure or a palpable pulse without the support of the intra-aortic balloon pump and atrioventricular pacing. Coarse atrial fibrillation was the underlying electrocardiogram rhythm in the absence of atrioventricular pacing. sodium bicarbonate was given without improvement. After discussion with the family, all life support measures were discontinued. The patient died 10 minutes after her arrival in the intensive care unit. alkaptonuria's pathogenesis is manifested as both local and systemic in nature. collagen vascular diseases share a similar pattern of multisystem involvement. Despite the negative outcome for the patient described, valuable insight can be obtained by studying this case and noting the anesthetic considerations specific to collagen vascular diseases in general.
