Atrial Natriuretic

A heterologous radioimmunoassay was used to measure the concentration of immunoreactive atrial natriuretic peptide (iANP) in plasma from the femoral artery of eight chloralose anaesthetized dogs. Mitral obstruction which increased left atrial pressure by 11 cmH2O increased plasma iANP from 97 ± 10.3 (mean ± SE) to 135 ± 14.3 pg/mL. Pulmonary vein distension increased heart rate but did not increase plasma iANP. Bilateral cervical vagotomy and administration of atenolol (2 mg/kg) did not prevent the increase in iANP with mitral obstruction. Samples of blood from the coronary sinus had plasma iANP significantly higher than simultaneous samples from the femoral artery confirming the cardiac origin of the iANP. Release of iANP depends on direct stretch of the atrium rather than on a reflex involving left atrial receptors.

Anomalous Pulmonary Venous Connection

The clinical, cardiac catheterization, and postmortem findings are presented in a 9-day-old infant with cor triatriatum, anomolous pulmonary venous connections, and a hypoplastic left ventricle. The dorsal accessory left atrial chamber did not communicate with the ventral or proximal left atrium, but did have a small connection with the right atrium. The left superior pulmonary vein connected with the accessory left atrium while the left inferior pulmonary vein connected with the proximal left atrium. The latter pulmonary venous connection has not been described previously in classical cor triatriatum and raises new embryological considerations.

Objectives To validate the safety and applicability of a previously unreported innovative technique: bipolar epicardial radiofrequency pulmonary vein ablation for the treatment of atrial fibrillation (AF) in conjunction with off-pump coronary artery bypass surgery. Methods After the completion of off-pump coronary artery bypass grafting (OPCAB) via sternotomy, patients underwent epicardial pulmonary vein ablation using a bipolar radiofrequency clamp placed on the left atrial cuff. The left atrial appendage was removed or excluded in all patients. Results Fifteen patients (aged 59–81 years) were treated and reviewed. An average of 2.8 ± 1 grafts were performed per patient; all patients received left internal mammary artery grafts. All sets of pulmonary veins were encircled successfully and ablated. Four patients had additional lesions placed. No patient had pulmonary vein injury. There were no reoperations for bleeding and no mortality. Preoperatively, AF was continuous in 4 patients and intermittent in 11; 10 patients were taking Coumadin preoperatively and 11 were taking antiarrhythmic drugs (AAD). At the follow-up evaluation (7.6 ± 4.4 months; range 1–16 months), 12 patients (80%) are in sinus rhythm (100% in the intermittent AF group, 25% in the continuous AF group); Coumadin has been discontinued in 5 of 10 patients (50% reduction) and AAD have been discontinued in 7 of 11 patients (74% reduction). Conclusions Bipolar radiofrequency epicardial pulmonary vein ablation can be safely and reproducibly used for the treatment of AF in conjunction with OPCAB. Patients with intermittent AF should be strongly considered for adjunctive treatment at the time of OPCAB.
