Seven years' outcome of simultaneous surgical treatment of atrial septal defect and atrial flutter in 2 children: case reports.

We describe 2 children who had long-standing type 1 atrial flutter and atrial septal defect. The simultaneous surgical treatment of these 2 conditions consisted of transmural incision from the inferior edge of the septal defect to the tricuspid ring, transmural incision from the medial-superior edge of the septal defect to the tricuspid ring, and closure of the septal defect with a bovine pericardial patch. There was no arrhythmia recurrence during a 7-year follow-up period.

[Off-pump myocardial revascularization in the elderly: analysis of morbidity and mortality].

Objective: To analyze the in-hospital outcome of elderly patients aged 70 years and older who underwent off-pump coronary artery bypass graft surgery with an intraluminal shunt in urgent, emergent, and elective coronary revascularizations.

Methods: From July 1989 to July 2005, we analyzed 87 patients ranging in age from 70 to 92 years. Of the 87 patients enrolled, 50 (57.

Approach of the pulmonary valve using right heart bypass and bicaval cannula: experimental study.

Objective: To reproduce the surgery for correction of pulmonary valve anomalies using right heart bypass and a new bicaval cuffed venous cannula for minimal access surgery.

Methods: Fifteen Large-White pigs were used for this study. The standard technique model was established with the first five pigs, the experiment was done with nine animals by sternotomy, and one was submitted to a minimally invasive procedure, but has been excluded of the sample.

Experimental evidence of regional myocardial ischemia during beating heart coronary bypass: prevention with temporary intraluminal shunts.

Background: Our center has been performing beating heart coronary artery bypass grafting with a temporary intraluminal shunt since 1983. Based on our clinical observations of more than 846 surgical cases, we believe that a temporary intraluminal shunt (TIS) greatly reduces the risk of the patient developing regional myocardial ischemia during clamping of the coronary artery. To seek evidence in support of our clinical observations, we evaluated the effects of coronary clamping with and without TIS in a porcine experimental model.
