Vascular complications of intraaortic balloon pumping: unsheathed versus sheathed insertion.

Incidence of vascular complications in intraaortic balloon counterpulsation is still high despite major refinements in catheter design and techniques. One hundred twenty-six patients in whom intraaortic balloon pumping was attempted were divided into two groups on the basis of insertion technique. Group 1 included 77 patients in whom the conventional percutaneous insertion was used. In group 2 (n = 45 patients), a sheathless insertion technique was used. The overall vascular complication rate was 19.6%, with the lower limb ischemia as the most common complication. The vascular complication rate was 25.9% in group 1 and 8.8% in group 2 (p < 0.01). Lower limb ischemia was noted in 17 patients in group 1 and 3 patients in group 2 (p < 0.01). These results suggest that sheathless insertion of the intraaortic balloon pump catheter can minimize vascular complications. This technique will be especially useful in patients with peripheral vascular disease, in whom the likelihood of vascular complications is high.

Exact positioning of intra-aortic balloon catheter.

The positioning of the intra-aortic balloon catheter in the descending aorta is vital for successful balloon pumping. With transesophageal echocardiography, the catheter could be properly and rapidly positioned in the descending aorta.

Intraoperative echocardiography: techniques and current applications.

Intraoperative echocardiography has opened new dimensions in the evaluation of cardiac surgical patients, and has contributed significantly to the improved surgical results. The use of intraoperative echocardiography has enabled the surgeon to image the working heart, to define the operative anatomy and physiology, and to evaluate the results immediately before the patients leave the operating room. This review summarizes the current status and applications of intraoperative echocardiography in the practice of cardiac surgery.

Left ventricular endoaneurysmorrhaphy: effect on left ventricular size, shape and function.

Left ventricular (LV) endoaneurysmorrhaphy is a relatively new surgical procedure with excellent results. Forty-five patients underwent surgical repair of LV aneurysm with LV endoaneurysmorrhaphy from 1991 to 1995. The main indication for operation was angina pectoris (71%). Concomitant myocardial revascularization was performed in 97% of the patients. The operative mortality rate was 2.2%. Pharmacologic inotropic support was required in 31% and mechanical support in 15%. Mean echocardiographic ejection fraction improved from 29.6% preoperatively to 48.3% postoperatively (p <0.001). LV end-diastolic volumes were 195 +/- 63 and 118 +/- 44 ml before and after surgery (p <0.01). Intraoperative transesophageal echocardiography revealed normal or near-normal LV shape in all cases. The mean follow-up was 34.0 +/- 9.2 months (16-50 months) and 1 patient died 9 months postoperatively. We conclude that endoaneurysmorrhaphy improves LV geometry and function in patients with LV aneurysms and can be performed with low surgical risk even in patients with large aneurysms and severely depressed LV function. ........

Two-dimensional and Doppler echocardiographic findings of congenital coronary artery fistula.

Three patients with coronary artery fistula confirmed by coronary angiography and surgery were studied using two-dimensional and Doppler echocardiography. Two of these patients had left coronary artery-right ventricle fistula. The proximal dilatation of the coronary arteries was visualized in all three patients by two-dimensional echocardiography. The course of the dilated right coronary artery and left circumflex artery was demonstrated by two-dimensional echocardiography in two patients. We were able to detect the disturbed flow at the drainage site in one patient by using the conventional Doppler echocardiography. In conclusion, it should be emphasized that two-dimensional and Doppler echocardiography can be useful methods in diagnosing coronary artery fistula.

Long-term results of patients with congenital complete atrioventricular block.

Congenital complete atrioventricular block is an uncommon disorder with a prognosis which is usually favorable. The disorder is sometimes associated with syncope, sudden death or cardiac pacing. It is difficult to determine the patients at risk of sudden death. In this retrospective study, hospital records of children who had been admitted to the Hacettepe University Children's Hospital between 1970-1990 for evaluation of complete heart block were examined. The study population, consisting of 39 children, 27 males and 12 females, had electrocardiograms consistent with complete heart block. These patients, diagnosed as having congenital complete A-V block, had an otherwise normally structured heart, and were followed up for a period of from one month to 15 years. Age at diagnosis ranged from 27 days to 17 years (mean: 86.9 +/- 48 months). Of the 14 patients with symptoms (five with syncope, eight with exercise intolerance and one with presyncope), nine were paced electively and have done well. Clinical and laboratory features of the asymptomatic and symptomatic groups were compared to evaluate potential risk factors.
