Megjegyzések:	This paper compares the late results of Kay's and de Vega's annuloplasty in the management of tricuspid incompetence. The operations were done in 62 consecutive patients during the nine-year period 1969-77 and included simultaneous correction of acquired valvular lesions (58/62) and congenital malformations (4/62). Kay's bicuspidalization and de Vega's annular plication were performed in 27 vs. 35 patients and these two groups were similar in the most important respects. Tricuspid regurgitation was recognized in 44/62 patients (71%) before surgery, whereas in 18/62 patients (29%) it was diagnosed at intra-operative exploration. The majority of cases (84%) were functional in origin and 16% had anatomical lesions causing or contributing to significant incompetence. Most of the patients (90%) belonged to functional class III or IV (N.Y.H.A.) before operation. The type of tricuspid repair had no bearing on early (11% vs. 14%) and late mortality (5.8%/year vs. 5.0%/year). Re-evaluation in 50 patients showed that Kay's bicuspidalization and de Vega's annular plication gave similar and good late result in about 70% of the cases. The risk of over-correction was low in that only 1/30 cardiac catheterization revealed signs of mild tricuspid stenosis. Recurrent or residual tricuspid incompetence is probably related to the severity of the individual cases. Some of these failures were evident already on the patient's discharge from hospital but, unfortunately, not predictable from the pre- or intra-operative evaluations.

Cím:	Haemodynamic changes after tricuspid valve surgery : a recatheterization study in forty-five patients / Árpád Péterffy, Rune Jonasson, Axel Henze
Dátum:	1981
ISSN:	0036-5580
Megjegyzések:	Changes of the central haemodynamics at rest and during exercise were evaluated in 45 patients who underwent tricuspid valve surgery. Tricuspid valve disease was associated with left heart valvular lesions in 42 patients, while isolated tricuspid valve lesions were present in 3 patients. The pre-operative evaluation showed marked impairment of cardiac function expressed by cardiomegaly, low physical working capacity, hypokinetic central circulation, elevated right atrial pressure and pulmonary hypertension in the majority of patients. Nineteen patients underwent tricuspid valve replacement and 26 tricuspid annuloplasty. The left heart valvular lesions were corrected by prosthetic valve replacement in all patients but one, who underwent mitral commissurotomy. The Björk-Shiley tilting disc valve prosthesis was used for all valve replacements. At postoperative evaluation the patients were classified in 3 groups: (1) Group TVR- 19 patients with well-functioning tricuspid valve prostheses; (2) Group TAP - 16 patients with good functional results in tricuspid annuloplasty; and (3) Group TAP-Failure - 10 patients in whom significant tricuspid incompetence was observed. The overall response to surgery in groups TVR and TAP was about the same, leading to an increase in working capacity and cardiac output and a decrease in heart volume, right atrial pressure and pulmonary hypertension. In the TAP-failure group, this response was limited to an increase in cardiac output and mainly attributable to the corrected left heart lesions. Sustained pulmonary hypertension, failing left ventricular myocardium, residual left heart lesions and anatomical tricuspid valve changes were the likely causes of TAP-failure, which could not be predicted from the pre-operative evaluation.
