Late postoperative follow-up of ostium secundum defect.

AIM: To perform late postoperative assessment of patients with ostium secundum defect. METHODS: We studied 45 patients 22+/-4 years after operation using clinical examination, transthoracic and transoesophageal echocardiography and electrocardiography. RESULTS: Patients operated on at </=24 years had normal exercise tolerance while 11/17 (65%) patients operated on at >24 years reported dyspnoea upon exercise. Mitral regurgitation occurred more frequently in patients operated on at </=24 years than at >24 years (29% vs 69%, P<0.05). Tricuspid regurgitation was mild in 20 patients (45%). There was an inter-atrial communication in 13 patients (28%). Eighteen patients (40%) had an enlarged right ventricular diameter. A tricuspid regurgitation gradient >30 mmHg was measured in seven patients (16%). Seventeen patients (38%) had significant electrocardiographic abnormalities. CONCLUSIONS: Late after uncomplicated seclusion of ostium secundum defect patients operated at >24 years have more symptoms than those operated on at an earlier age. Residual lesions are common. Mitral regurgitation is more frequent in patients operated on at >24 years. Our findings support the clinical consensus of operating on these patients in their childhood and adolescence.

Aortic valve stenosis causing a left-to-right shunt in persistent left superior vena cava communicating with the left atrium.

This study demonstrated a rare anomaly of a persistent left superior vena cava draining into the left atrium in a patient with developing left-to-right shunt caused by bicuspid aortic stenosis. The venous system, including the coronary sinus, was otherwise normal. We believe that, in this anatomic situation, a marked increase in left ventricular impedance caused a moderate left-to-right shunt from the left atrium into the left innominate vein. At operation, the aortic valve was replaced with a mechanical prosthesis and the anomalous vein was ligated. The convalescence was uneventful.

Treatment of sinoatrial syndrome with permanent cardiac pacing in 90 patients.

Out of a pacemaker population of 392 patients, 90 (23%) have been found to have sinoatrial syndrome. Their ages ranged from 22 to 86 years, and averaged 66 for men and 70 for women. The male-to-female ratio was 1:1.6. Before pacemaker implantation, syncopal attacks had occurred in 54%, dizziness without syncope in 31% and tachyarrhythmias in 57%. Atrial or paroxysmal supraventricular tachycardia had been recorded in 33%, atrial fibrillation or flutter in 28%, and ventricular tachycardia in 11%. First and/or second degree AV block was found in 36%. Coronary heart disease was present in 61% and 20% had had myocardial infarction. Cardiomyopathy and previous carditis were other associated heart diseases. Sinoatrial syndrome was the only manifestation of heart disease in 20%. Follow-up time after pacemaker implantation ranged from 3 months to 7 years, mean 23 months. Syncopal attacks were stopped in 48 of 49 patients, dizziness was relieved in all 28 patients and tachyarrhythmias were controlled by combined drug treatment in 43 of 51 patients. Nineteen patients died during the follow-up, most of them of cerebrovascular events or myocardial infarction. Associated coronary heart disease was especially frequent in this group. The death of one patient was caused by a run-away pacemaker. Other pacing failures were due to electrode movement or premature battery exhaustion. There was no mortality associated with pacemaker implantations or replacements. These results strongly support the view that pacemaker treatment most effectively controls symptoms of sinoatrial syndrome when drug treatment fails.
