Benefits of Cardiac Resynchronization Therapy in an Asynchronous Heart Failure Model Induced by Left Bundle Branch Ablation and Rapid Pacing Jingfeng Wang*1, Zhenning Nie*1, Haiyan Chen*2, Xianhong Shu2, Zhaohua Yang3, Ruiming Yao1, Yangang Su1, Junbo Ge1 1Department of Cardiology, Shanghai Institute of Cardiovascular Diseases, Zhongshan Hospital, Fudan University, 2Department of Echocardiography, Shanghai Institute of Medical imaging, Shanghai Institute of Cardiovascular Diseases, Zhongshan Hospital, Fudan University, 3Department of Cardiac surgery, Shanghai Institute of Cardiovascular Diseases, Zhongshan Hospital, Fudan University The establishment of a chronic asynchronous heart failure (HF) model by rapid pacing combined with left bundle branch ablation is presented. Two-dimensional speckle tracking imaging and aortic velocity time integral are applied to validate this stable HF model with left ventricular asynchrony and the benefits of cardiac resynchronization therapy.

Acute Aortic Dissection in Pregnant Women General Thoracic and Cardiovascular Surgery. | Pubmed ID: 25085319 Acute aortic dissection occurring during pregnancy represents a lethal risk to both the mother and fetus. Management of parturient with acute aortic dissection is complex. We report our experience of two pregnancies with type A acute aortic dissection. One patient is a 31-year-old pregnant woman (33rd gestational week) with a bicuspid aortic valve and the other is a 32-year-old pregnant woman (30th gestational week) with the Marfan syndrome. In both cases, a combined emergency operation consisting of Cesarean section, total hysterectomy prior to corrective surgery for aortic dissection was successfully performed within a relatively short period of time after the onset. Both patients' postoperative recovery was uneventful, and we achieved a favorable maternal and fetal outcome.
