[Reoperation in mitral valve reconstructive surgery].

UNLABELLED: In the past few years reconstructive surgery of the mitral valve has experienced a growing popularity. It is now clearly established that restoration of a normal function valve is preferable to valve replacement. The authors report the results of the mitral valve reconstructive surgery in a population of 701 patients with high incidence of restrictive lesions of rheumatic fever. This represents an experience of 14 years. 5.1% of patients who underwent mitral valvuloplasty required late reoperation for recurrent mitral valve dysfunction. Repeat mitral valve repair resulted in successful treatment for 40% of these patients. CONCLUSION: The mitral valve repair failure are: 1--Procedure related: (58.1%); a--surgical technical related--35.8%; b--no ring implantation (in restrictive lesions)--15%; c-rupture of previously chordae shortened--7.4%. 2--Valve related: (41.9%); a--progressive primary valve disease--(25.4%); b--wrong surgical indication--(15%); c--endocarditis--(1.5%).

[Grawitz tumor with invasion of the inferior vena cava and right atrium: surgical management with a multidisciplinary team].

In this paper, the clinical condition of a 56 year old male patient is reported, with the diagnosis of renal cell carcinoma, complicated by a tumoral thrombus, extended from the renal vein into the vena cava and right atrium, who underwent surgical treatment. The operation consisted in the radical nephrectomy associated to the vena caval thrombectomy, under extracorporeal circulation, utilizing a multidisciplinary team composed by urologists, vascular and cardio-thoracic surgeons. The main features related to the diagnosis and surgical management of this case are described and discussed, according to data taken from the most recent publications of the literature on the subject.

[Results of Dor's endoventricular repair in the management of left ventricular aneurysms].

INTRODUCTION: Left ventricular aneurysms are serious long-term complications from acute myocardial infarction that produce hemodynamic alterations in the cardiac function. OBJECTIVE: The aim of this study is to evaluate the chirurgical and clinic results of the endoventricular patch repair of the akinetic or dyskinetic portions of the left ventricle. METHODS: From August 2002 to October 2005, 20 consecutive patients underwent surgical repair of left ventricular aneurysm using the endoventricular patch repair technique. The mean age was 63,6 years, and 80% where male. Every patient have had only one episode of acute myocardial infarction, which resulted in a akinetic or dyskinetic alteration in the motility of the left ventricle. The preoperative functional class of most of the patients was class III or IV and 45% where on angina class II. In 90% of the patients the ventricular aneurysm where antero-septal. Left ventricular dysfunction was present in 65%. RESULTS: All patients underwent the Dor procedure associated with coronary artery bypass grafting. There was no perioperative mortality. One patient died in the immediate postoperative period. Four patients needed inotropic support for more than 24h and intra-aortic balloon pumping was used postoperatively in two cases. Mean hospital stay was 8,6 days. At late follow-up the functional class was I in 20%, class II in 55% and class III in 10%. The angina class was I in 65% of the cases. CONCLUSIONS: The surgical repair of left ventricular aneurysm using the endoventricular patch repair technique proved to be safe, causing significant clinical improvement and an increase in the ejection fraction.
