Surgical resection of right atrial neurilemoma extending to pulmonary vein

Surgical resection of right atrial neurilemoma extending to pulmonary vein.

An asymptomatic cardiac neurilemoma was found in a 33-year-old woman. The tumor was on the anterior surface of the right atrium extending to the right upper pulmonary vein across the interatrial groove. The tumor was resected completely and right atrium, interatrial septum, left atrium and right superior pulmonary vein were reconstructed with cardiopulmonary bypass. The patient recovered uneven...

Scimitar vein anomaly with total right-side pulmonary vein return to inferior vena cava concomitant with atresia of upper right-side pulmonary vein and secundum atrial septal defect.

Scimitar vein is the partial anomalous pulmonary venous connection usually draining lower pulmonary lobe to the inferior vena cava or right atrium. We present a scimitar vein anomaly in a 34-year-old woman with the uncommon association of a secundum type of atrial septal defect and atretic right upper pulmonary vein. She presented with increasing dyspnea for 2 months, however, she was asymptoma...

Left atrial-pulmonary vein reentrant tachycardia following pulmonary vein isolation.

Pulmonary vein isolation has become the cornerstone of ablation for atrial fibrillation. However, it is sometimes followed by the development of left atrial macro-reentrant tachycardia. There is evidence to suggest that the myocardial sleeves within the pulmonary veins may be implicated in the mechanism of the tachycardia. Here we present a case of a post-ablation macro-reentrant tachycardia, i...

Incremental value of isolating the right inferior pulmonary vein during pulmonary vein isolation procedures in patients with paroxysmal atrial fibrillation.

Electrical isolation of the left superior, left inferior, and right superior pulmonary veins (PVs) is often, but not always, effective in eliminating paroxysmal atrial fibrillation (PAF). The incremental clinical value of also isolating the right inferior PV has not been well defined. PV isolation by ostial applications of radiofrequency energy guided by PV potentials was performed in 176 conse...
