Surgical treatment of cardiac myxomas: a 20-year follow-up.

Clinical experience in the diagnosis and management of 50 cases of cardiac myxoma seen over a 20-year period from 1974 to 1994 has been reviewed. There were 17 men and 33 women of mean age 55.2 (range 16-81) years. Echocardiography confirmed the diagnosis in all patients. The location of myxomas was as follows: left atrial alone in 42 patients, right atrial alone in three, right ventricular alone in one, left atrial+right atrial in two, left atrial+right atrial+right ventricular in one, and left atrial+left ventricular in one. Nineteen patients were operated on within 48 hours of the diagnosis. All tumours were successfully removed with the aid of cardiopulmonary bypass. The hospital mortality rate was 10%. Excision of the tumour resulted in marked symptomatic improvement. There was one late death. The current survivors are symptom-free at a mean follow-up of 76.4 (range 1-241) months. Echocardiographic studies were performed in all survivors and no recurrences have been observed. It is concluded that excision of cardiac myxomas is curative and long-term survival is excellent. Radical tumour excision may prevent recurrences.

Repair of coarctation of the aorta in adults with simultaneous aortic valve replacement and coronary artery bypass grafting.

The authors present three patients who had either coronary artery disease or severe aortic stenosis or both along with congenital coarction of the aorta. The use of a heterotopic bypass (Dacron tube implanted between the ascending and descending aorta) allowed the surgeons to correct the coarction through a median sternotomy and perform the coronary artery bypass grafting and valve replacement at the same time. The authors are convinced that the scarcely mentioned heterotopic bypassing of the coarcted aorta should be added to the armamentarium of the surgeons who operate on patients with coarctation or recoarctation of the aorta in adulthood or with coarctation that is associated with cardiac lesions.

[Long-term results of surgical treatment of cardiac myxomas].

We have reviewed our clinical experience in the diagnosis and management of 50 cases of cardiac myxoma seen over a 20 year period, 1974 to 1994. There were 17 males and 33 females, their ages ranged from 16 to 81 years (mean 55.2 years). Echocardiography confirmed the diagnosis in all patients. The location of myxomas was as follows: left atrial alone in 42 patients, right atrial alone in 3, right ventricular alone in 1, left + right atrial in 2, left + right atrial + right ventricular in 1, and left atrial eft ventricular in 1. Nineteen patients were operated on within 48 hours following the diagnosis. All tumors were successfully removed with the aid of cardiopulmonary bypass. The hospital mortality rate was 10%. Excision of the tumor resulted in marked symptomatic improvement. There was one late death. The current survivors are asymptomatic at a mean follow-up of 76,4 months (range 1-241 months). Echocardiographic studies were performed in all survivors and no recurrences have been observed. We conclude that excision of cardiac myxomas is curative and long-term survival is excellent. Radical tumor excision may prevent recurrence.

The use of an internal mammary artery for creating a systemic-to-pulmonary artery shunt.

We report on two patients who had systemic-to-pulmonary artery shunts created by the use of the internal mammary artery (IMA). The first patients was operated on more then 30 years ago (the case has never been published) and the second one move recently. We give a brief summary of the ten cases of the same operation published so far, and emphasize the usefulness of the IMA that stays open despite the initially poor run-off and is capable of supplying increasing amounts of blood to the growing pulmonary arteries.

Valve repair in infective endocarditis.

From 1985 to 1995, 12 patients with native valve endocarditis underwent valve repair instead of replacement. Mean age was 41.9 years (range from 5 to 79 years). Eight patients had active and 4 patients inactive infection. The mitral valve was involved in 6 patients, the aortic valve in 1, both valves in 2, the tricuspid valve in 2, and the mitral and pulmonary valves in 1. The pathological findings were as follows: leaflet perforation in 2 patients, chordal rupture in 3, and vegetations in 10. Valve sparing procedures were carried out on the mitral valve in 8 patients, on the aortic valve in 1, on the tricuspid valve in 2, and on the pulmonary valve in 1. The following repair techniques were used: vegetectomy in 10 patients, leaflet patching in 2, posterior mitral leaflet resection in 3, mitral annuloplasty in 4, and pulmonary valve repair in 1. Uncontrolled sepsis, progressive heart failure, peripheral embolism, and echocardiographically demonstrated vegetations were the indications for surgery. There was no operative or late mortality and all infections were cured with no recurrences. One patient required valve replacement following aortic valve repair because of progressive aortic regurgitation. Postoperative Doppler echocardiography showed trivial to no regurgitation in 11 patients after valve repair. The overall outcome was favorable during the mean follow-up period of 39.3 months (range from 1 to 120 months). Reparative or reconstructive approaches for native valve endocarditis should be considered and can be successfully performed. Their advantages include (1) improved hemodynamics, (2) no recurrence, (3) no mortality, and (4) favorable long-term results.

Cor triatriatum dextrum simulating right ventricular myxoma and pulmonary stenosis.

A case of enormous Chiari's network in a 7-year-old girl is described. It formed a parachute or spinnaker-like sack which moved freely into the pulmonary artery causing mild pulmonic stenosis. The preoperative diagnosis was believed to be myxoma of the right ventricle. The real condition was recognized during the operation. This is the seventh reported case of correction of so-called cor triatriatum dextrum.

Accessory mitral valve tissue causing left ventricular outflow tract obstruction.

Among the various causes of left ventricular outflow tract obstruction accessory mitral valve tissue is the least common. To the best of our knowledge there have been only five such cases reported to date. The aim of presenting two more cases and reviewing the literature is to bring attention to this rare anomaly as it is easy to treat provided it has been diagnosed preoperatively or recognised at surgery.
