Congenital coronary artery obstruction associated with aortic anomalies in children: report of two cases.

Coronary arterial obstruction associated with congenital aortic valve disease is rare in children. We studied two children with aortic valve disease and symptoms of coronary insufficiency. Cineangiography revealed localized obstruction of the proximal left coronary artery.

Successful triple coronary artery bypass in a child with multiple coronary aneurysms due to Kawasaki's disease.

A 9-year-old girl developed ischemic cardiac symptoms 3 years after she first presented with characteristic manifestations of Kawasaki's disease, namely, high fever, conjunctivitis, lymphadenopathy, macular truncal skin rash, and erythema of both hands followed by desequamation of the skin of the fingertips. This acute illness resolved spontaneously within 2 weeks. Because of progressive and severe anginal symptoms and electrocardiographic signs of myocardial ischemia, she underwent cardiac catheterization and coronary angiography, which demonstrated multiple aneurysms of both right and left coronary artery systems.

[Surgical valve therapy combined with aorto-coronary bypass (author's transl)].

The AA. analyse a series of 720 patients who have undergone an aorta coronary by-pass combined with surgical valve therapy at the Texas Heart Institute up to an including 1977. 384 of these cases involved the aortic valve, 306 the mitral valve and 30 both valves.

Direct myocardial revascularisation: experience with 9364 operations.

Between July 1968 and December 1976, 9364 consecutive patients with coronary insufficiency underwent direct myocardial revascularisation using aortocoronary bypass (ACB). Among these patients 8017 had ACB alone, and the remaining 1347 had ACB in addition to correction of other cardiac and vascular lesions. In the series of patients having ACB alone the hospital (early) mortality was 3.

IDENTIFICATION OF LARGE LEFT ATRIAL THROMBUS BY CROSS-SECTIONAL AND M-MODE ECHOCARDIOGRAPHY.

In addition to a typical pattern indicative of mitral stenosis, the M-mode echo-cardiogram of a patient with mitral valve disease revealed a broad band of dense echoes within an enlarged left atrial cavity that was suggestive of an intraatrial thrombus. Subsequent cross-sectional echocardiography demonstrated a globular cluster of echoes inside the left atrial cavity, thus corroborating our interpretation of the M-mode recording. When open mitral commissurotomy was performed, a large, partially calcified thrombus was found protruding from the posterior wall and left atrial appendage into the atrial cavity.

DELAYED STERNAL CLOSURE: A USEFUL TECHNIQUE TO PREVENT TAMPONADE OR COMPRESSION OF THE HEART.

Closure of the sternotomy incision was limited to the skin in four critically ill patients following cardiopulmonary bypass. One patient had sustained an intractable bleeding diathesis and the other three had ventricular distention which prevented approximation of the sternum. All patients survived after delayed closure and repair of the sternotomy.

Sinus venosus atrial septal defect: early and late results following closure in 109 patients.

The clinical course of 109 patients who underwent closure of a sinus venosus atrial septal defect is reviewed, with emphasis on the incidence, type, and severity of arrhythmias before and after operation. There were no operative deaths and only 1 late death. No instances of obstruction of the superior vena cava were detected clinically.

Reoperation following direct myocardial revascularization.

Among the 5507 patients who underwent aortocoronary bypass between October 1969 and June 1975, 41 patients (0.007%) developed recurrent angina and required reoperation. The factors necessitating reoperation were graft thrombosis in 10 patients (24%), progression of disease in 12 (29%), graft thrombosis and critical unbypassed lesions in one (2.

Ascending aorta-abdominal aorta bypass: indications, technique, and report of 12 patients.

Use of the supraceliac segment of the abdominal aorta for ascending aorta-abdominal aorta bypass (AAAAB) offers a new technique for management of certain difficult surgical problems. Since 1973, we have performed AAAAB in 12 patients: 4 with recurrent coarctation of the thoracic aorta; 4 with coarctation of the thoracic aorta and associated cardiac lesions requiring a concomitant intracardiac procedure; 2 with recurrent aortoiliac occlusive disease (AIOD); 1 with interruption of the aortic arch requiring concomitant pulmonary artery banding; and 1 with coarctation of the abdominal aorta. In 3 of these patients (2 with recurrent AIOD and 1 with coarctation of the abdominal aorta) the distal anastomosis was made to the distal abdominal aorta or femoral arteries.

UNUSUAL CASE OF PULMONARY ARTERIOVENOUS FISTULA CONCEALED BY THE CARDIAC SILHOUETTE ON CHEST ROENTGENOGRAM.

A large pulmonary arteriovenous fistula was discovered in a patient with long-standing cyanosis, clubbing and dyspnea, with no other cardiovascular signs or symptoms and a normal chest roentgenogram at the time of cardiac catheterization and pulmonary angiography. The fistula was overshadowed by the cardiac silhouette. Surgical resection was successful.

Surgical treatment of aneurysms of the ascending aorta.

From January 1970 to April 1975, 132 patients underwent surgical repair of aneurysms of the ascending aorta at this institution, 24 of whom had acute dissections. In almost all cases the ascending aorta was replaced with a Dacron tube graft. Aortic valve replacement was performed in 100 patients and 23 patients underwent coronary artery revision or bypass.

Surgical versus medical treatment of coronary artery disease: long-term survival.

In an attempt to answer the question as to whether or not aortocoronary bypass (ACB) does increase life expectancy of patients with coronary artery occlusive disease (CAOD), 4,766 consecutive patients undergoing ACB at the Texas Heart Institute from October, 1969 through June, 1975, were reviewed and followed for five and one half years. Overall early mortality was reduced from 9.7 percent during the first full year (1970) of the study to 3.

Aortocoronary artery bypass: present indications and risk factors.

From 1969 through 1974, a total of 4,522 patients were operated on for coronary artery occlusive disease. This article is an in-depth analysis of a consecutive series of 275 of these patients, operated on during 1974. The mortality was 1.

Aortocoronary bypass in Jehovah's Witnesses: review of 46 patients.

The hemodilution technique for cardiopulmonary bypass using blood substitutes for priming has permitted open heart operations in Jehovah's Witnesses who refuse to accept blood, and has reduced the need for massive blood transfusion in certain procedures including aortocoronary bypass. A series of 46 Jehovah's Witness patients underwent aortocoronary bypass procedures. Of these, two patients died, representing a mortality of 4.

Treatment of severe coronary artery disease with quadruple and quintuple saphenous vein grafts. Review of 100 consecutive patients.

In order to establish the anatomic criteria, the functional results, and the safety of complete myocardial revascularization for severe coronary artery disease, 100 consecutive patients who received four or five saphenous-vein grafts were analyzed. Ages ranged from 37 to 75 years (mean, 56 years). Men predominated by a ratio of 12:1.

Long-term survival following coronary artery bypass. Analysis of 4,522 consecutive patients.

A consecutive series of 4,522 patients who received aortocoronary bypass (ACB) from October 1969 through December 1974 has been analyzed with respect to cumulative (actuarial) survival, cause of late death, and late postoperative complications. Through December 1973, 2,676 patients received ACB alone. Cumulative survival was 85.

Surgical palliation of tricuspid atresia.

In the 20-year period ending December 31, 1973 we operated on 105 patients for palliation of tricuspid atresia (TA) with reduced pulmonary blood flow. Pott's anastomosis (85), Blalock-Taussig anastomosis (19), intrapericardial aorta (Ao)-to-right pulmonary artery (RPA) (18), Glenn procedure (3) and miscellaneous shunts (2) have been used. Of patients undergoing operation more than 15 years ago, 45% (9/20) are still alive.

The value of moderate hypothermia during anoxic cardiac arrest for coronary artery surgery.

Anoxic cardiac arrest, as opposed to induced ventricular fibrillation, greatly facilitates accurate distal anastomosis in aortocoronary bypass surgery. In order to diminish the anoxic insult, general and topical hypothermia may be used. In an attempt to establish the value of moderate hypothermia during anoxic cardiac arrest two groups of patients were compared.
