The study was performed in 33 patients with echocardiographic diagnosis of mitral valve prolapse (PVM), without any other associated heart disease. A 19 derivations electrocardiogram (ECG) was performed a direct inscription 4 channel Samborns 150 machine at 25 and 50 mm/sec. The purpose of the study was determine the alterations in ventricular depolarization and repolarization, and to correlate them with valve prolapse, as well as with cavitary and parietal dimensions, as measured by M mode and/or two-dimensional echocardiography. Left ventricular hypertrophy detected by ECG agreed with the ECO test in 77%; the sensitivity was of 86% and specificity of 67.5%. Left ventricular hypertrophy detected by ECG was not related with the type of prolapse. Ventricular repolarization alteration was very frequent (84.8%). Association of this parameter with initial notch of R in a VF becomes important for diagnosis suspicion (p less than 0.01). When the abnormal repolarization affected the anterolateral wall, posterior valve prolapse was frequent; when the posteroinferior region was the affected one, the prolapse occurred more frequently in both valves. An important correlation (p less than 0.01) was found between left ventricular dilatation detected by ECO and the abnormal ventricular repolarization.

Due to the considerable progress made by instrumental total body diagnostics (ECO, CAT, RMN, angiography, etc.) in recent years heart surgery has increasingly often been used to treat pathologies which are not primarily cardiac but which see the involvement of the heart and large vessels in the advanced stages of cancer and non-cancer diseases of other organs or apparatus. This is the case of malignant renal or adrenal tumours which infiltrate along the caval lumen until they reach the right atrium. In these cases caval and atrial involvement must be seen as a prolapse of the tumour and not a long-distance metastasis: prognosis only appears to be linked to the hemodynamic impairment caused by the obstacle to systemic lower venous drainage. On the bases of this observation radical surgery may be justified at a renal, caval and cardiac level. The authors report their preliminary experience in 6 patients with renal cancer (4 renal carcinoma, 1 Wilm's tumour, 1 adrenal carcinoma) who underwent combined surgery, in a single stage, involving enlarged nephrectomny and caval and atrial thrombectomy, the latter performed in profound hypothermia and cardiocirculatory arrest. Two patients died later and 4 are living, in good condition and with perviousness of the lower caval venous drainage. Similar to other analogous experience reported in the literature, the authors suggest taking a combined approach performed in a single stage into consideration for these patients.
