Primary cardiac tumors: forty years' experience with 71 patients.

BACKGROUND: Primary cardiac tumors are infrequent, and few cardiac surgeons have extensive experience in treating them. The majority of the tumors are benign. As noninvasive diagnostic imaging of cardiac masses continues to improve, the number of these tumors that are seen by clinicians will increase. More of the malignant tumors may be curable if detected at an earlier stage. METHODS: A retrospective review was conducted of all patients with primary cardiac tumors managed by a university teaching center over a period of 40 years, using hospital medical records and a Provincial cardiovascular surgery database. RESULTS: Seventy-one patients (25 males and 46 females) with primary cardiac tumors were identified. Fifty-seven (80%) were benign masses and 14 (20%) were malignant masses. Twenty-eight percent of the tumors in men were malignant (7 of 25) compared with only 15% in women (7 of 46). Seventy-two percent of the masses were located in the left atrium. Forty-three percent of tumors in the right atrium were malignant (6 of 14) compared with only 14% in the left atrium (7 of 51). Complete resection was possible for 50 of 52 benign atrial tumors (96%) but for only 5 of 14 malignant tumors (36%). There was one perioperative death (1.4%). Three patients had no surgery because of their poor medical condition. Two of the patients with unresectable malignant tumors were still alive at last follow-up. The remaining 12 patients with malignancy have all died of their disease. CONCLUSIONS: Primary cardiac tumors are uncommon. Most patients present with symptoms of congestive heart failure. The second most common presenting symptom is embolization. Improvement in noninvasive diagnostic technology has increased the number of patients identified with a primary cardiac tumor and has also increased the number referred for surgical resection. The majority of left atrial tumors were benign, whereas up to one-half of tumors found in the right atrium were malignant. A greater proportion of malignant primary tumors were found in men than in women. Malignant cardiac tumors tend to be diagnosed after they have become extensive and the patients already have a very grave prognosis.

Blunt cardiac rupture. The Emanuel Trauma Center experience.

OBJECTIVE: To analyze the factors affecting outcome in patients with blunt cardiac rupture, including anatomical cardiac injury, associated injury, clinical presentation, age, mechanism of injury, diagnostic method, surgical intervention, and presence of vital signs in the field and on arrival. DESIGN: Retrospective review. SETTING: A community-based level I trauma center. PATIENTS: A consecutive series of 27 patients seen between 1984 and 1993. MAIN OUTCOME MEASURE: Survival with return to preinjury activity. RESULTS: Eleven patients (41%) survived resuscitation, surgery, and initial hospital care. Survivors had a lower mean Injury Severity Score (38) than nonsurvivors (62) (P < .05). Three (33%) of nine patients who arrived with no blood pressure or viable electrical heart rhythm survived. No patient survived rupture of two cardiac chambers. CONCLUSIONS: Patients with blunt cardiac rupture who present with cardiac arrest can survive. Nonsurvivors tend to have more associated injuries, as indicated by higher Injury Severity Scores. Our institution's overall survival rate of 41% (11/27) compares favorably with rates at other trauma centers.

Extracorporeal cardiopulmonary life support with heparin-bonded circuitry in the resuscitation of massively injured trauma patients.

BACKGROUND: Patients who have massive but potentially survivable injuries frequently die from complications of hypovolemia, hypoxemia, hypothermia, metabolic acidosis, and coagulopathy. Emergency cardiopulmonary bypass has been unsuccessful in preventing such deaths because it involves systemic anticoagulation that exacerbates coagulopathy. PATIENTS AND METHODS: A simplified extracorporeal cardiopulmonary life support (ECLS) system was assembled consisting of a centrifugal pump head, heat exchanger, membranous oxygenator, percutaneous cannulas, and heparin-bonded circuitry. The entire system has heparin-bonded surfaces. Patients were resuscitated with the system after femoral vein-femoral artery cannulation. ECLS was used to resuscitate massively injured patients who were deteriorating despite maximal conventional therapy. RESULTS: While receiving maximal conventional therapy, 6 patients developed hypothermia, metabolic acidosis, and coagulopathy causing pulmonary hemorrhaging and hypoxemia from severe underlying lung injuries. ECLS with heparin-bonded circuitry provided cardiopulmonary support and rewarming while physicians addressed coagulopathies and surgical bleeding and assessed survivability. Three patients survived. CONCLUSIONS: ECLS with heparin-bonded circuitry offers supplemental capability in the resuscitation and cardiopulmonary support of selected massively injured patients while their primary injuries are being evaluated and treated.

'The broken halo sign': a fractured calcified ring as an unusual sign of traumatic rupture of the thoracic aorta.

Two elderly patients, involved in separate motor vehicle accidents, sustained blunt chest injury resulting in rupture of their thoracic aortas. The initial chest radiographs showed the presence of a calcified ring fractured in two places with lateral displacement of a calcified fragment by haematoma. This 'broken halo sign' is a radiographic sign not previously well described in the literature. The presence of a disrupted aortic ring in the elderly patient, associated with the appropriate mechanism of injury, should alert the clinician to the potential diagnosis of traumatic rupture of the thoracic aorta (TRTA).
