Left atrial dilatation in constrictive pericarditis: a pre and post-operative echocardiographic study.

Thirty-three surgically proven cases of constrictive pericarditis were studied pre-operatively by echocardiography for left atrial dilatation and 18 of them underwent post-operative study at a mean follow-up period of 229 +/- 105 days. The degree of left atrial dilatation in these patients was compared with patients of restrictive cardiomyopathy (n = 8) and sex matched controls of similar age (n = 33). Significant left atrial dilatation was present in patients of constrictive pericarditis compared to controls and it was of a similar or greater degree compared to patients of restrictive cardiomyopathy (the left atrium to aorta ratio was 1.7 +/- 0.31, 1.53 +/- 0.18 and 1.07 +/- 0.1, in constrictive pericarditis, restrictive cardiomyopathy and controls, respectively, P = NS for constrictive pericarditis vs. restrictive cardiomyopathy and P < 0.001 for constrictive pericarditis vs. controls). There was no correlation of degree of left atrial dilatation with clinical and hemodynamic variables. Postoperatively, there was regression of left atrial size in patients with normal hemodynamics (n = 12, pre- vs. post-operative left atrium to aorta ratio 1.65 +/- 0.23 vs. 1.32 +/- 0.14, P < or = 0.001) and persisting or increasing left atrial dilatation in patients with persisting hemodynamic abnormality (n = 6, left atrium to aorta ratio 1.66 +/- 0.23 vs. 1.82 +/- 0.15, P = NS). We conclude that significant left atrial dilatation is a consistent echocardiographic feature of constrictive pericarditis. Hemodynamic normalization following successful pericardiectomy is associated with regression of atrial size.

[An unusual case of annular constrictive pericarditis--a "framed heart"].

We presented a 62-year-old female with constrictive pericarditis of an unusual anatomy. A calcified constrictive band, 2-3 cm wide, ran parallel to the frontal plane, coursing circularly along the anterior aspect of the great arteries, right atrium, diaphragmatic surface of the right ventricle, posterolateral aspect of the left ventricle and back to the great arteries. The course of the constrictive band was circular but completely different from that of typical annular constrictive pericarditis in which a constrictive band runs along the atrioventricular groove. Hemodynamic consequences of our patient was rather non-specific impairment of ventricular filling than functional valvular stenoses due to external compression characteristic for the typical annular constrictive pericarditis. Effective surgical relief of the constriction was accomplished under cardiopulmonary bypass and cardioplegic cardiac arrest.

Differentiation of constrictive pericarditis and restrictive cardiomyopathy using digitized echocardiography.

Constrictive pericarditis and restrictive cardiomyopathy are difficult to distinguish at the bedside and occasionally at routine cardiac catheterization. Left ventricular diastolic function was studied by computer analysis of digitized M-mode echocardiograms in four patients with constrictive disease and three with restrictive disease, and the data were compared with those of normal subjects. The respective distinguishing echographic features of constrictive pericarditis and restrictive cardiomyopathy were as follows: the major filling period of the left ventricle was 78 +/- 9% of normal versus 128 +/- 4% (p less than 0.01), minimal left ventricular dimension to peak filling interval was 50 +/- 10 versus 110 ms (p less than 0.05) and the maximal rate of left ventricular posterior wall thinning was -4.9 versus -2.3 seconds-1 (p less than 0.05). This preliminary study suggests that it may be possible to accurately diagnose the two disease entities using this technique at the bedside and to avoid cardiac catheterization.

[Pericardiectomy for post-coronary artery bypass grafting constrictive pericarditis; strategy for safe and complete pericardiectomy].

Surgery for constrictive pericarditis after coronary artery bypass grafting (CABG) needs complete pericardiectomy without injury to bypass grafts. We performed pericardiectomy for post-CABG constrictive pericarditis 15 months after the first surgery. Preoperative multislice helical 3-dimensional computed tomography (CT) clearly demonstrated the patent bypass grafts and anatomical relationship between grafts and surrounding organs. Among surgical approaches, we chose bilateral thoracotomy to avoid injury to the bypass grafts and to obtain a good surgical exposure, especially for pericardiectomy of the left side of the heart. Additionally, with the use of intraoperative doppler ultrasound blood flowmetry, we could safely achieve complete pericardiectomy. We conclude that the combined application of 3-dimensional CT, bilateral thoracotomy and doppler ultrasound blood flowmetry was a supreme strategy for the operation of constrictive pericarditis after CABG.

[Experience with the surgical management of constrictive pericarditis].

61 patients were operated on for constrictive pericarditis at the Cardiovascular Surgical Clinic of Semmelweis Medical University in the last 33 years. The average hospital mortality of the surgical pericardiectomy was 4.9%. The final conclusions of this retrospective and follow up study are as follows: pericardiectomy is the method of choice in the treatment of constrictive pericarditis, since it does not has any therapeutic alternative, its hospital mortality is low and it results excellent early and late postoperative functional effects.
