Diastolic Cardiac Function

Background: Renal artery stenosis (RAS) often plays an important role not only in malignant hypertension but also in sudden development of heart failure (HF) so called ‘flash pulmonary edema’ or chronic HF refractory to medical treatment. One of the possible mechanisms whereby RAS affects these unique conditions of HF is suppression of LV compliance through the complex interaction between neurohormonal systems originating from the reduction of renal blood flow. Renal artery angioplasty is expected to be an effective treatment for restoring renal blood flow in patients with RAS. The aim of the present study was whether the angioplasty can improve the impaired neurohormonal systems and diastolic cardiac function in patients with RAS. Methods: A prospective analysis was performed in 18 HF patients with RAS (age: 72±6, 3 females, NYHA I/II/III: 5/9/4) who underwent renal artery angioplasty between 2005 and 2007. Four patients with significant bilateral RAS and 3 patients with unilateral RAS in the vessel supplying a functional solitary kidney were included. We monitored the changes of biochemical and neurohormonal markers and blood pressure. Cardiac function was evaluated by tissue Doppler echocardiogram before and 3 months after the procedure. Results: Technical success was achieved in all interventions. The results are shown in table . Systolic arterial blood pressure significantly decreased by renal angioplasty. B-type natriuretic peptide (BNP) was significantly reduced 3 months after the angioplasty, whereas the change of sCr or angiotensinII was not statistically significant. Myocardial early diastolic velocity (Em), a parameter of diastolic LV function, was significantly improved compared with that measured before the procedure. Conclusions: In patients with either overt or latent HF possessing RAS, renal artery angioplasty not only decreases arterial blood pressure but also improves diastolic cardiac function in parallel with the reduction of BNP level.

Abstract Renal Auto transplantation (RAT) is the surgical procedure in which the kidney is initially removed and subsequently re-implanted in a different position, allowing for improved outcomes in conditions involving ureteral pathology, renovascular and neoplastic disease primarily. In this paper, we aim to build upon the understanding of RAT and especially its effectiveness in treating patients with hypertension secondary to renal artery disease, intolerant to previous treatment approaches. In particular, the ex-vivo technique will be focused upon as introduced by Ota et al. in 1967 whereby the use of the workbench is frequently applied for patients requiring in excess of 45 minutes of ischaemic time. We, therefore, put forth two cases managed in co-operation by the University of Arkansas vascular and urology departments. The first of which was a 52-year-old woman with an aneurysmal Lesion reaching the renal artery at the hilum. The second was an 18-year-old woman with Takayasu arteritis. The use of vasopressin had preserved some renal function however at the time of the diagnosis, they were experiencing difficulty in controlling their hypertension, and thus RAT was performed, and the subsequent patient postoperative outcomes and effectiveness have been recorded and analysed as part of this study.
