Cryoablation for surgical treatment of chronic atrial fibrillation combined with mitral valve surgery: a clinical observation.

Objective: Although the classical Cox-Maze III is the gold standard surgical therapy with a proven efficacy in the treatment of atrial fibrillation (AF), complexity of this procedure has resulted in a search for a simpler, less invasive and more cost-effective method. In this study we evaluated the results of cryosurgical ablation in the treatment of chronic AF in patients undergoing concomitant mitral valve surgery.

Methods: Ninety patients (mean age: 50.

Complete surgical repair of Tetralogy of Fallot in adults, is it ever too late?

A minority of patients with Tetralogy of Fallot (TF) survive into adulthood. These patients have been subjected to a prolong period of cyanosis and hypoxia. The aim of this study is to assess the benefits of total correction of TF in this adult population.

Anticoagulation for prosthetic heart valves in pregnancy. Is there an answer?

The aim of this retrospective study was to compare the different anticoagulation regimens used in pregnant women with prosthetic heart valves. We reviewed 196 pregnancies in 110 women from 1974 to 2000. The patients were divided into two groups: group 1 (142 pregnancies) had warfarin throughout pregnancy; and in group 2 (54 pregnancies), warfarin was replaced by subcutaneous heparin during the first trimester and last two weeks of pregnancy.

Is extended arch aortoplasty the operation of choice for infant aortic coarctation? Results of 15 years' experience in 181 patients.

Background: Recurrent coarctation is an ever-present complication of surgical treatment of coarctation of aorta (CoA) among infants. No single operation appears to have a clear superiority.

Methods: From January 1, 1986, to June 30, 2002, a consecutive series of 181 patients less than 1 year of age (range 1 to 300 days, median 13.

Traumatic aortic transection: evidence for the osseous pinch mechanism.

Acute traumatic transection of the thoracic aorta is most commonly seen in vehicular trauma and is generally accepted to be due to differential deceleration. A second mechanism is proposed for this injury and that is the osseous pinch mechanism. We report a case where aortic transection occurred due to a crush injury and supports the latter mechanism.
