The anomalies of drainage of systemic venous communications to the heart are many. But only few cause significant hemodynamic alteration and thus, complications. When they do, they need to be surgically corrected. We report an unusual case of a patient who was found to have left pulmonary veins draining into the left superior venacava (LSVC), which in turn was opening into the roof of the left atrium that had unroofed coronary sinus morphology. Innominate vein was absent. LSVC was divided cranial to where the pulmonary veins were draining into it. Lower end was suture closed. Proximal part of the LSVC was anastamosed to left pulmonary artery.

The growth in percutaneous transluminal devices has enabled operators to tackle more complex, native, and post-bypass surgery anatomy. However, complications such as coronary artery dissection, coronary perforation, retrograde aortic dissection, arrhythmias, and acute coronary syndrome still occur with resulting mortality rates of up to 4.2% in complex interventions. Perforation of the circumflex artery is of particular interest in view of its position and relation to the surrounding cardiac structures. This is a site of potential fluid collection, and as the left atrium is fixed to the parietal pericardium at the entry of the pulmonary veins, fluid in the oblique sinus can accumulate enough pressure to compress the left atrium and the coronary sinus. We present a case of left circumflex artery perforation which demonstrates the physiologic complications of coronary sinus and left atrial compression and the resultant functional mitral stenosis.

SummarySince February 1990, we have attempted nonsurgical occlusion of persistent patency of the arterial duct using the Rashkind double-disk occluding device, of either 12 or 17 mm diameter. Results are presented from 31 patients (23 female and eight male, ages 15 months to 16 years). M-Mode, cross-sectional, Doppler and color Doppler echocardiographic studies were made prior to closure, in the following 24 hours, and six months later. Left ventricular diastolic dimension and shortening fraction, systolic intervals, and left atrium/aortic ratio were evaluated by M-Mode echo. We examined carefully the location of the device relative to the left pulmonary artery and descending aorta, also checking for disturbed flows and residual shunts. These studies showed a clear tendency for the left ventricular diameter to decrease, and revealed a significant normalization of the left atrium/aortic ratio. Successful closure of the duct was achieved in 27 cases. Follow-up studies six months later showed residual shunting in four cases. In one patient, a second device was implanted with an excellent result. At the immediate follow-up, turbulences were noted in the area of the device (nine cases) and in the left pulmonary artery (seven cases). Distortion of the anatomic orientation of the left pulmonary artery was observed in three cases in which we discovered 20 mm Hg systolic gradients. In our opinion, echocardiography is the best technique with which to follow-up these patients. The high sensitivity of color Doppler echocardiography revealed minimal distortion of the left pulmonary artery, probably generated by regional anatomic adjustment to the insertion of the device.

AbstractThe unusual case of an infant with aortic origin of the left pulmonary artery is presented. The patient developed a rare complication of lobar emphysema due to bronchial compression from the enlarged right pulmonary artery. Operative anastomosis of the left pulmonary artery to the pulmonary trunk was successful, with subsequent resolution of the lobar emphysema.

1. We have studied the extensibility of circumferential strips of main pulmonary artery and large pulmonary veins obtained at post mortem from patients of all ages, dying from conditions other than heart and lung disease. 2. The vessel strips were submitted to increasing loads in a tension balance. The pulmonary arteries were found to be readily extensible. This extensibility became less with increasing age. The pulmonary veins were virtually inextensible at all ages. 3. It is postulated that the large extraparenchymal pulmonary veins have a capacitative role in supplying blood from the lungs to the left atrium. This may be accomplished by their collapsible nature, as they have little capability of distension.

The vein of Marshall (VOM) is an attractive target during ablation of atrial fibrillation due to its autonomic innervation and its location anterior to the left pulmonary veins and drainage in the coronary sinus. We studied 14 dogs. A coronary sinus venogram showed a VOM in 10, which was successfully cannulated with an angioplasty wire and a 2 mm balloon. In 5 dogs, electroanatomical (Carto) maps of the left atrium were performed at baseline and after ethanol (100%, 4 – 8 cc) was infused in the VOM, which demonstrated the creation of a new crescent-shaped scar in the left atrium, extending from the annular left atrium towards the posterior wall and left pulmonary veins. In 4 dogs, both cervical vagal trunks were isolated in the carotid sheath and cuff stimulation electrodes were attached to them. Effective refractory periods (ERP) were measured in 3 sites of the left atrium, before and after high-frequency bilateral vagal stimulation. The baseline ERP was 113.6±35.0 ms, and decreased to 82.2±25.4 ms (p<0.05) after vagal stimulation. After alcohol infusion in VOM, vagally-mediated ERP decrease was eliminated (from 108±27.2 ms to 95.6 ±16.7ms, p=NS). This elimination of vagal effects was not uniform and was limited in sites in proximity with the VOM (baseline ERP 105±18.7ms vs post vagal 98.±37.6ms, p=NS, as opposed to 106.7±27.1ms vs post vagal 73.3±19.7ms, p<0.05, in sites remote to VOM). We also tested feasibility of VOM alcohol infusion in humans: 2 patients undergoing pulmonary vein antral isolation had successful VOM cannulation: left atrial voltage maps demonstrated new scar involving the infero-posterior left atrial wall extending towards the left pulmonary veins. Retrograde alcohol infusion in the VOM achieves significant left atrial tissue ablation, abolishes local vagal responses and is feasible in humans.
