Abstract

Bland-White-Garland (BWG) syndrome is a rare congenital heart disease in which the left coronary artery originates from the pulmonary artery (PA). Surgical treatment to rebuild a dual coronary system is recommended at the time of the diagnosis. However, no effective operative procedure has been established for adult-type BWG patients because of the paucity of such cases. We herein report a case of adult-type BWG that was successfully treated by patch closure of the orifice of the left main tract from the main PA and coronary artery bypass grafting. 123 I-15-(p-iodophenyl)-3-(R,S)-methylpentadecanoic acid (BMIPP) and 201 thallium (Tl) dual myocardial single-photon emission computed tomography (SPECT) were performed before surgery, early after surgery, and at three months after surgery. Before surgery, dual SPECT showed myocardial perfusion defects in the anterior and septal wall, which corresponded to the cardiovascular magnetic resonance imaging findings. Early after surgery, only 201 Tl images demonstrated an improvement in the defect area. At three months after surgery, both the 201 Tl and 123 I-BMIPP imaging findings demonstrated an improvement in the defect area, which was correlated with the recovery of the left ventricular function. These results showed the effectiveness of this surgical approach for BWG syndrome. < Learning objective: Adult-type Bland-White-Garland syndrome is a rare congenital disease and no effective operative procedure has been established because of the paucity of such cases. The patient in this report underwent patch closure of the orifice of the left main tract from the main pulmonary artery and coronary artery bypass grafting. Myocardial dual single-photon emission computed tomography was considered to be effective for evaluating the results of revascularization surgery, and an improved uptake on 123 I-15-(p-iodophenyl)-3-(R,S)-methylpentadecanoic acid images was closely related to an improvement in the left ventricular function.>., (© 2019 Japanese College of Cardiology.

Abstract

Objectives: Atrial septal pacing via a trans-septal breakthrough site within the right atrial septum can shorten global atrial activation time, resulting in significant reduction of recurrence of atrial fibrillation events. This study examined whether this pacing method will lead to resynchronization of atrial contraction and its benefit on hemodynamic function can be maintained for 24 months., Methods: Thirty patients with atrial fibrillation and delayed atrial conduction were enrolled (17 males, 13 females, mean age 73 +/- 7 years). Trans-septal breakthrough site within the right atrial septum was identified through pacing from the dorsal left atrium. Continuous atrial septal pacing at the trans-septal breakthrough site was performed for 24 months. Time difference (TD) between right and left atrial contractions was measured during atrial septal pacing and sinus rhythm by pulse Doppler echocardiography of the trans-tricuspid (P-At) and mitral (P-Am) blood flows (TD = P-Am - P-At)., Results: The atrial lead was screwed near the fossa ovalis in 29 of 30 patients. Atrial septal pacing yielded significantly shorter P wave duration (101.9 +/- 10.4 vs 139.6 +/- 14.7 msec, p < 0.001), leading to significant reduction of TD in atrial contraction (-8.8 +/- 10.0 vs 29.8 +/- 13.6 msec, p < 0.001)as compared to sinus rhythm. Both shorter P wave duration and reduced TD during atrial septal pacing remained statistically significant during the follow-up period as compared to sinus rhythm. Both left atrial diameter and A to E ratio of filling waves at mitral valve were significantly decreased at 12 months and remained decreased at 24 months., Conclusions: Atrial septal pacing at the trans-septal breakthrough site can resynchronize atrial contraction and results in improved hemodynamic effects during 24 months of follow-up.
