Perpendicular insertion of Dacron patch for aortoplasty in adult coarctation of aorta to increase circular elasticity.

Circular elasticity cannot be obtained in standard patch aortaplasty in patients with coarctation of aorta. We inserted Dacron patch perpendicularly to standard fashion. The creases of Dacron patch became parallel to descenden aorta. Circular elasticity, that reduces both true and false aneurysm incidence in the long-termperiod, can be obtained with this modification.

Considerations in the surgical management of infantile coarctation of aorta.

The results of a recent 5 year experience with resection of coarctation of the aorta in infants less than 1 year of age are compared with those of an earlier series from the same institution. The significant improvement in mortality and morbidity statistics is attributed to modifications in operative and postoperative care. Operative mortality has decreased from 38 to 17 percent and the incidence rate of significant restenosis has diminished from 60 to 33 percent. It is suggested that in patients with large associated intracardiac shunt banding of the main pulmonary artery should be performed before resection of the coarctation. Three of five patients have survived procedures performed in this sequence. Microsurgical techniques and careful approximation of the aortic lumen with interrupted sutures are the major factors responsible for the reduced incidence of recoarctation. Prolonged ventilatory support postoperatively with the occasional addition of controlled positive airway pressure and continued aggressive medical therapy for heart failure are recommended.

Combined brachial and femoral approach to balloon angioplasty in coarctation of aorta.

Transfemoral balloon angioplasty of native aortic coarctation was initially not feasible in two patients, because of inability to cannulate the femoral artery percutaneously in one, and to cross the coarctation in the other. The percutaneous brachial approach helped overcome both these problems, after which utilization of intravascular snares allowed successful transfemoral completion of angioplasty.

Coarctation of aorta with unusual association of diverticulum of the left ventricle and double orifice mitral valve.

We describe a case of coarctation of aorta with two unusual associated anomalies, namely, a diverticulum of the left ventricle and double orifice of the mitral valve. Echocardiography and colour flow mapping precisely diagnosed the bridging tongue of leaflet tissue responsible for the double orifice of the mitral valve. Balloon angioplasty for coarctation produced dramatic benefits which are sustained at follow-up. The other two lesions caused no haemodynamic abnormality.

Coarctation of aorta with special reference to infants. Long-term results of operation in 126 cases.

A review of 126 cases of coarctation of the aorta confirms the need for surgical resection in infants with intractable congestive cardiac failure. The high association with additional cardiovascular abnormalities in patients presenting in early infancy contributes significantly to the mortality. Patients with large ventricular septal defects and coarctation of the aorta are at risk and may require pulmonary artery banding at the time of resection of the aortic coarctation. Long-term complications included restenosis (18 cases) and persistent hypertension (10 cases). In order to prevent persistent hypertension, it is suggested that elective resection of the coarctation be done at 1 year of age.

[A successful staged complete repair in a neonate with coarctation of aorta, ventricular septal defect, and left ventricular outflow tract obstruction--a new palliative operation].

An eight day old neonate with coarctation of aorta (CoA), ventricular septal defect (VSD), and severe left ventricular outflow tract obstruction (LVOTO) underwent a successful staged repair following a new palliative operation, which comprised aortic arch reconstruction, PTFE bypass graft between main pulmonary artery and descending thoracic aorta, and pulmonary artery banding (PAB) distal to the graft. Insertion of the bypass graft was aimed to allow enough systemic blood flow and reduces after load of ventricles after PAB. The second staged definitive operation was performed 21 days after the first operation and the procedure comprised partial resection of posterioly deviated infundibular septum via VSD, patch closure of VSD, and division of the graft. No evidence of progression of LVOTO was noted until the second stage operation despite the tight PAB. This new palliative operation, which does not need aid of cardiopulmonary bypass, is particularly effective for those with LVOTO, and can be safely applied even to seriously ill neonate. Thus, for the staged repair in aortic arch obstructive disease with VSD and severe LVOTO, this procedure can be a good alternative for palliative operation.

[Reconstructive surgery in 59-year-old patient with coarctation of aorta under the monitoring of somatosensory evoked potential and spinal cord perfusion pressure].

Postoperative paraplegia is a relatively rare complication in reconstructive surgery for coarctation of the aorta and the operative treatment is usually performed without any adjuncts. A 59-year-old male patient underwent replacement of descending thoracic aorta with vascular prosthesis under the monitoring of SEP and spinal cord perfusion pressure (SCPP) [pressure difference between mean distal aortic pressure (MDAP) and the cerebrospinal fluid pressure (CSFP)]. During cross-clamping of the aorta, MDAP decreased from 61 to 40 mmHg and CSFP increased from 6 to 15 mmHg, SCPP was 25 mmHg, and the amplitude of the SEP waves rapidly decreased. As the ischemic changes of spinal cord were suspected, the aortic cross-clamping was released. The amplitude of SEP recovered to the preoperative level immediately after de-clamping. In order to prevent spinal cord ischemia, the partial cardio-pulmonary bypass was employed, and SCPP was maintained above 60 mmHg, so that SEP did not show any ischemic changes during cross-clamping of the aorta. The patient did not develop any neurological deficit postoperatively. The monitoring of SEP and SCPP appears to be useful for prevention of postoperative paraplegia in the surgical treatment for coarctation of the aorta.

Cerebrovascular abnormalities in postoperative coarctation of aorta. Four cases demonstrating left subclavian steal on aortography.

Fifteen children, aged 0.3 to 10.5 years (mean 3.8 years) after repair of coarctation of the aorta, underwent cerebral arteriography as part of postoperative catheterization. Four manifested central nervous system symptoms postoperative catheterization. Four manifested central nervous system symptoms postoperatively: Two had persistent headaches, one had exercise-induced hemianopsia and one had major motor seizures. All four had greater blood pressure in the right arm than in the left and evidence of subclavian steal, with retrograde filling of the left vertebral and left subclavian arteries on selective right vertebral arteriography. Ligation of the left vertebral artery in three patients and left subclavian graft arterioplasty in one resulted in disappearance of symptoms. None of the 11 asymptomatic patients manifested cerebrovascular anomalies, and no patient in the series had berry aneurysm. This study suggests that patients with central nervous system symptoms and a disparity of blood pressure in the arms after surgery for coarctation of the aorta should be evaluated carefully to exclude subclavian steal as the cause of the symptoms.

Plasms renin acitivity in coarctation of aorta before and after surgery.

Plasma renin acitivity was measured in II cases of coarctation of the aorta before and after operation. The values of plasma renin activity in the recumbent position before operation were significantly lower than in the control group. After surgery plasma renin activity rose to normal levels. There was no correlation between plasma renin activity levels and arterial blood pressure. The renin-angiotensin system seems not to be involved directly in the maintenance of hypertension in patients with aortic coarctation.

The surgical treatment of coarctation of the aorta.

Patients with coarctation of the aorta have a significantly decreased life expectancy. Surgical correction is curative and involves a low mortality rate which increases with coexisting cardiovascular abnormalities. In our series, there were no operative deaths in patients with pure coarctation of the aorta. Age is an important factor and postoperative complications were more frequent in older patients. Re section of the narrowed area with end-to-end anastomosis is the technique of choice. If theis is not possible, a Dacron tube is a good alternative. Early diagnosis and early intervention are of utmost importance, even in asymptomatic patients.

Morphological characterisation of ventricular septal defects associated with coarctation of aorta by cross-sectional echocardiography.

Cross-sectional echocardiograms of 18 neonates and infants with coarctation of the aorta and ventricular septal defect were retrospectively assessed. With a combination of subcostal and precordial cuts the site and anatomical relations of the defects were determined. In one case there was a muscular trabecular ventricular septal defect. Three had a malalignment defect with associated left ventricular outflow tract obstruction. In two there was a doubly committed subarterial defect with associated malalignment of the point of continuity between the aortic and pulmonary valves and the crest of the trabecular septum. Twelve cases had a perimembranous defect, with varying degrees of extension into the inlet, trabecular, or outlet septum. In this group 10 had associated aortic override, with varying degrees of left ventricular outflow tract narrowing. Abnormal insertion of the tricuspid valve was observed in 10 cases, such that it partly obscured the ventricular septal defect. Thus in most cases of coarctation with ventricular septal defect, the morphology of the ventricular septal defect and ventricular outflow tracts is such that left ventricular ejection is directed towards the pulmonary artery rather than the aorta.

The risk of having additional obstructive lesions in neonatal coarctation of the aorta.

Infants with coarctation of the aorta may have obstructions at other sites within the left heart which are not always apparent on the initial echocardiogram. The magnitude of the risk of having the additional obstructions is not well described, with few reliable quantitative criterions for identifying patients at the highest risk. We determined the frequency of additional, late appearing, stenotic lesions within the left heart, and the predictive morphologic features on the initial cross-sectional echocardiogram. We identified all patients with coarctation of the aorta diagnosed by 3 months of age, excluding those with complex cardiac disease or definite additional stenotic lesions at presentation, leaving 101 patients for study. At follow-up, 31 stenotic lesions were diagnosed in 23 patients, 15 of whom had at least 1 intervention. Mitral stenosis was diagnosed in 11 patients, aortic stenosis in 10, subaortic stenosis in 8, and supravalvar aortic stenosis in 2. The probability for freedom from obstructive lesions was 81% at 1 year, 74% at 3 years, and 70% at 5 years. Echocardiographic predictors of mitral stenosis included smaller mitral valvar annuluses, presence of a mean transmitral gradient between 2.5 and 5.0 mmHg, and elongation of the area of intervalvar fibrous continuity. Predictors of aortic stenosis were smaller mitral valvar annuluses, an initial aortic valvar gradient between 15 and 20 mmHg, and obliteration of the commissure between the right and non-coronary leaflets of the aortic valve. Predictors of subaortic stenosis were smaller mitral valvar annuluses and elongation of the area of intervalvar fibrous continuity. Patients with Z-scores for the diameter of the mitral valve of less than -1 were at the highest risk for manifesting obstructive lesions at any level. Associated stenoses in the left heart are common in the setting of aortic coarctation. When Doppler data is equivocal, features of the cross-sectional echocardiogram can identify the sub-group of infants at increased risk.

Balloon angioplasty before Wheat's operation in a patient with Turner's syndrome.

The case of a 19-year-old woman with Turner's syndrome, dissecting aneurysm of the ascending aorta, coarctation of the aorta and bicuspid aortic valve stenosis is presented. Balloon angioplasty was performed before surgery to relieve the pressure gradient caused by coarctation of the aorta. Successful surgical treatment was carried out using Wheat's method. Four-year follow-up has revealed no signs of complications such as restenosis or aneurysm formation.

[Coarctation of aorta with right aortic arch and anomalous left subclavian artery].

The occurrence of coarctation in patients with right aortic arch is extremely rare. We have encountered a 21-year-old man with anomalous left subclavian artery. He was diagnosed when he was 13. On angiography he exhibited a right aortic arch. The left common carotid artery, right common carotid artery and the right subclavian artery diverged from the proximal side of the coarctation. The left subclavian artery diverged from the distal side. The right brachial arterial pressures measured 158-72 mmHg, while the left brachial arterial pressures measured 98-80 mmHg. Clinical studies revealed no vascular ring and no other anomalies were found in this patient. An attempt at treatment was made with extra anatomical bypass grafting from the ascending aorta to the descending aorta. No pressure difference due to coarctation remained after operation.

[Surgical treatment of coarctation of the aorta].

Repair of coarctation of the aorta was performed in 37 cases (31 patients, 6 patients of reoperation) ranging from 4 days old to 15 years old. Subclavian flap repair were performed in 15, resection and end-to-end anastomosis in 14, patch aortoplasty in 6, and interposition graft in 2. Subclavian flap angioplasty or end-to-end anastomosis is considered the procedure of choice in infants. However, the incidence of reoperation significantly increased in patients younger than age one month at initial subclavian flap repair. Mechanism of recurrent coarctation may be possibly related to retention of abnormal tissue, which is possibly ductal and/or intimal shelf, with the potential for proliferation and luminal narrowing. We suggest that in applicable case end-to-end anastomosis rather than subclavian flap angioplasty may be the surgical technique of choice in infants less than one month of age, and the most common reoperation technique was patch aortoplasty in re-stenosed cases.
