Valve surgery at the Hospital de Cardiología y Neumología del Centro Médico Nacional IMSS.

From January 1964 until February 1985, we performed 8,370 prosthetic valve procedures; this represents 54.32% of our total surgical load. Approximately 93% of the replacements were for rheumatic valve disease; the rest were for ischemic, myxomatous, degenerative, congenital, and traumatic heart disease. All cases were between New York Heart Association (NYHA) Classes II and IV; almost all patients had heart catheterizations before surgery. During the last 6 years, all patients had echocardiograms before undergoing heart catheterization.

[Tricuspid atresia. Clinical course in 120 children].

We describe the clinical course of 120 children with tricuspid atresia (TA) attended in the Hospital de Cardiología y Neumología, "Dr. Luis Méndez", del Centro Médico Nacional. There were 61 males and 59 females. The age of presentation was in 79 newborn babies, seventeen between one and six months old, 20 between six and 24 months old, and four with two or more years old. The clinical picture was hypoxic spells in 89% and congestive heart failure in the others. The chest film showed cardiomegaly in 85%, with diminished pulmonary flow in 48%, increased flow in 27.5%, and normal in 9%. The electrocardiogram with superior left axis deviation in 94%, right atrial hypertrophy in 58%, left atrial hypertrophy in 47.5% and left ventricular hypertrophy in 96%. TA was classified as type I in 103 children, type Ic in 70, Ib in 27 and Ia in six, and type II in seventeen children, with eight IIc, six IIb and three IIa. In 44 the management was medical, 63 underwent systemic-pulmonary anastomosis, 37 of them with Blalock-Taussig shunt and Fontan procedure in thirteen children. There were 21 deaths. This survey is compared with the literature and from this point we make management recommendations.

[Surgery in children with atrial septal defects without cardiac catheterization].

We describe the results of surgical repair of atrial septal defects in 36 children who did not undergo pre-op cardiac catheterization. These cases were seen at the Hospital de Cardiologia y Neumología Dr. Luis Méndez del Centro Médico Nacional. There were 24 (67%) females and twelve (33%) males. The mean age was 6.4 +/- 2.4 years with a range from three to thirteen. All cases had auscultatory findings typical of atrial septal defect. Five patients with associated tricuspid murmur (chest film showed grade I cardiomegaly in 21 (58.3 per cent), grade II cardiomegaly in fifteen (41.7 percent). Pulmonary artery shadow was normal in 24 (66.6 percent) and increased in twelve (33.3%). Pulmonary blood flow was increased in all of them. Electrocardiogram showed sinus rhythm in 35 (97.2%). In one instance left atrial rhythm; all EKGs demonstrated right axis deviation, complete right bundle branch block and right ventricular hypertrophy with diastolic overload. Only three had right atrial hypertrophy. The M-mode echocardiogram showed right ventricular dilatation in all and paradoxically septal motion in 26 (72.2%). Two-dimensional echo with the subxiphoid view allowed direct visualization of the defect in all cases. We performed contrast echocardiogram in eight cases and Doppler echocardiogram in six of them. Cardiac surgery findings were ostium secundum atrial septal defect in 34 (94.4%). Two of them also had partial anomalous venous connection. All had uneventful recovery. We conclude that in typical atrial septal defects operative repair is feasible without prior cardiac catheterization.

[Infectious endocarditis of the heart valves and valvular prostheses. report of 21 cases].

During 1978, and 1979, the Surgery Division of The Cardiology and Pneumology Hospital of The National Medical Center (Mexican Institute for Social Security), studied and treated surgically twenty one cases -- in twenty patients -- of infectious endocarditis. Nine patients had an active infection in the heart valves and twelve in the prosthesis. The survival rate of the first group was 88.88% and of the second group 58.33%. The causes of death were due to the hemodynamic damage that the valvular or prosthetic dysfunction leads to, when there is a delay in the arrival of the patient to a medical unit of third level. The conventional medical treatment applicable to a reduced number of cases whose characteristics are discussed do not operate when dealing with patients with infected prosthesis or valve infections caused by non-gram positive bacteria. We conclude that this problem demands a better approach, principally surgical, to improve the prognosis of these patients.

[Esophageal and tracheal compression caused by vascular ring].

Eight infants with anomalous vessels of the aortic arch were submitted to surgical operation of the structures interfering with tracheal and esophageal function. Four patients had an aberrant right subclavian artery; three had a double aortic arch with a left ligamentum arteriosum. None had congenital heart disease. One had a tracheoesophageal fistula and a short esophagus. Esophagograms and aortograms were performed in all. Tracheal and esophageal compression was relieved in the four boys and the four girls. All are alive and in good condition.

[Traumatic rupture of the aorta. A report of a case operated on with success].

The purpose of this paper is to present the case of a patient with traumatic rupture of the aorta, that was diagnosed and treated successfully. We describe the clinical data and diagnostic procedures of this case and we analyze the diagnostic and treatment aspects in accordance to the review of the literature. If, as in this case, the lesion does not extend through the adventitia and the entity is suspected based on the mechanism of the traumatism, a successful surgical treatment is feasible. This can be done by only clamping the aorta and doing the repair without an atrium to aorta by-pass, as was done in this case with no complications, or with the use of such a by-pass with a centrifugal pump with which it might be possible to prevent, in some cases, the paraplegia that can be associated with the clamping of the aorta. We conclude that a high degree of suspicion and a precise surgical technique are mandatory for a successful treatment of a traumatic rupture of the aorta.
