  ABSTRACT: Although the aortic valve-sparing procedure has gained popularity in recent years, it still remains challenging in patients with advanced aortic regurgitation (AR). We compared the long-term outcomes of the aortic valve-sparing procedure with the Bentall operation in patients with advanced aortic regurgitation secondary to aortic root dilatation. A retrospective review of 120 patients who underwent surgery for aortic root dilatation with moderate to severe AR between January 1999 and June 2009 was performed. Forty-eight patients underwent valve-sparing procedures (valve-sparing group), and 72 patients underwent the Bentall procedure (Bentall group). The two groups' overall survival, valve-related complications, and aortic valve function were compared. The mean follow-up duration was 4.9±3.1 years. After adjustment, the valve-sparing group had similar risks of death (hazard ratio [HR], 0.61; p=0.45), and valve related complications (HR, 1.27; p=0.66). However, a significant number of patients developed moderate to severe AR in the valve-sparing group at a mean of 4.4±2.5 years of echocardiographic follow-up (p<0.001). Both the Bentall operation and aortic valve-sparing procedure showed comparable long-term clinical results in patients with advanced aortic regurgitation with aortic root dilatation. However, recurrent advanced aortic regurgitation was more frequently observed following valve-sparing procedures.

  Article: Axillofemoral Bypass to Treat Severe Heart Failure Caused by Takayasu's Arteritis.

  ABSTRACT: Takayasu's arteritis is an inflammatory vasculitis that primarily affects the aorta and its major branches. Involvement of the thoracic and abdominal aortas, although rare, causes marked hypertension and may lead to severe heart failure. We report the improvement of cardiac function after axillofemoral bypass grafting in a 59-year-old woman who had this condition.

  Article: Cardiac angiosarcoma on the right atrium: two cases.

  Won Kyoun Park, Sung-Ho Jung, Ju Yong Lim
  [show abstract] [hide abstract]
  ABSTRACT: We detected two cases of right atrial angiosarcoma that had a similar appearance on imaging studies. Although the surgical findings were similar for the two patients, one had a clear resection margin, while the other had tumor cells in the resection margin on frozen biopsy. We suggest that preoperative data on magnetic resonance imaging and computed tomography in patients with angiosarcomas may not predict the exact extent of surgical resection or prognostic outcomes.
