Comparative StudyExperience with bidirectional cavopulmonary anastomosis and modified Fontan operation in patients with single ventricle and concomitant visceral heterotaxy.
The object of our study was to analyze the results of bidirectional cavopulmonary anastomosis (BCPA) and modified Fontan operations (MFO) in patients with a functionally single ventricle and heterotaxy syndrome and to reveal risk factors for these surgical interventions. During 1983-2010, 681 patients underwent BCPA or MFO. Thirty-nine had heterotaxy syndrome. ⋯ The independent risk factor for lethal outcomes after BCPA and MFO was preoperative regurgitation at atrioventricular valves (P=0.012). BCPA and MFO in patients with a functionally single ventricle and heterotaxy syndrome allow to significantly improves their quality of life. Preoperative regurgitation at atrioventricular valves worsens surgical results.

Aortic valve reconstruction using self-developed aortic valve plasty system in aortic valve disease.
Aortic valve disease is usually treated by prosthetic valve replacement. We have performed aortic valve plasty (AVP) using glutaraldehyde-treated autologous pericardium. AVP was performed for 88 patients from April 2007 through August 2009. ⋯ The peak PG became 12.9±5.8 mmHg. Ten patients showed no AR, 20 patients showed trivial AR, and two patients showed mild AR. Freedom from reoperation is 100% at three years follow-up.

Reoperation for ascending aorta false aneurysm using deep hypothermia and circulatory arrest.
Ascending aorta false aneurysms after cardiac surgery are uncommon. Resternotomy is hazardous and may result in massive and uncontrollable hemorrhage if the false aneurysm is entered. Here we report our experience with the use of deep hypothermia and circulatory arrest to avoid this risk. ⋯ Resternotomy under circulatory arrest and deep hypothermia is a safe technique well-adapted to patients with an ascending aorta false aneurysm.

Case ReportsNegative-pressure pulmonary edema presented with concomitant spontaneous pneumomediastinum: Moore meets Macklin.
Negative-pressure pulmonary edema is an unusual complication mainly associated with general anesthesia. It is caused by excessive negative intrathoracic pressure following a deep inspiration against an acute airway obstruction. The resultant decreased intrathoracic pressure amplifies venous return to the right heart and increases pulmonary capillary wedge pressure that can be further amplified by massive sympathetic discharge due to hypoxia. ⋯ We experienced a case of negative pulmonary edema which presented in association with SP. Pneumomediastinum is probably caused by an excessive positive intrathoracic pressure for a subsequent expiration against a closed airway. In the present case, both complications resolved with conservative management.

Case ReportsEnucleation of calcium core and in-situ valve replacement for massive posterior mitral annular calcification.
A 67-year-old female was admitted to our hospital for surgical treatment of the aortic and mitral valvular disease. She had chronic renal failure and dialysis was started 13 years previously. ⋯ The posterior mitral annulus was reconstructed using equine pericardium and aortic and mitral valve replacement was performed. The postoperative course was uneventful.
