Redo Heart transplantation in a high-risk patient due to severe aortic regurgitation and accompanying right ventricular failure after LVAD implantation and temporary RVAD support

Abstract: After 19 months of continuous flow LVAD and temporary RVAD assistance for one month, we present a 62-year-old patient who underwent redotopic Heart transplantation due to acute aortic regurgitation. In comparison to right-sided ECMO implantation, the patient received a heartware LVAD and annuloplasty of the tricuspid valve as a result of end-stage heart failure and severe tricuspid regurgitation. In immediate post-operative echo, minimal aortic regurgitation was found, but in the sequel to thoracic echocardiograms, the severity of aortic regurgitation was increasing in both right and left ventricular functions, with increasing intensities in both right and left ventricular functions. The patient was referred to urgent heart transplantation and completed 19 months after the LVAD implantation, according to Thatu2019s. Conclusion: severe aortic regurgitation is a definite complication after cf-LVAD implantation, which in our case was managed safely with orthotopic heart transplantation in this high-risk patient.

Ocular pulse amplitude and visual field changes in patients diagnosed with aortic regurgitation.

Objectivity: In the patients treated with aortic regurgitation, there is a correlation between ocular pulse amplitude, intraocular pressure, and visual field deterioration. Methods Twenty-nine patients with AR diagnosis without glaucoma history as part of the study were divided into three groups, with the AR group and 32 healthy controls as the control group. Sixteen of 32 healthy people and 14 of 29 AR patients were female, as shown by the following lines: The measurement, which was conducted at 15:30 during the diffusion IOP tests with the Pascal DCT was found to be statistically significant in the AR group. When the healthy individuals and patients diagnosed with AR were compared, it was found that there was a statistically significant positive correlation in terms of the significant GSS 2 stage. Conclusion In patients with AR, there was no significant rise in IOP, but VF deficiencies were discovered in patients with AR.

Predictors of heart failure and all-cause mortality in asymptomatic patients with moderate and severe aortic regurgitation.

AR attributable signs or left ventricular ejection fractions 50% are typical of class I recommendations for severe chronic aortic regurgitation. As noninvasive measurements of elevated LV filling pressures have been used to forecast heart failure readmission and all-cause mortality in HF patients, we hypothesize that elevated LVFP's may also be predictors of HF and ACM in chronic AR. Methods We developed a single center patient registry of moderate to severe AR diagnoses between 2003 and 2008 and followed each patient until January 2013. Patients with a high AR and moderate AR had similar EuroScore II values as well as a similar incident HF and ACM. Conclusions Elevated TR speed and EH were strong indicators of HF and ACM in patients with asymptomatic severe AR and moderate AR.

Sutureless aortic valve replacement in pure aortic regurgitation: expanding the indications.

Patients with a pure aortic regurgitation are not eligible for transcatheter therapy and, therefore, require another less invasive surgical option. We wanted to explore our findings with sutureless aortic valve replacement in patients with symptomatic pure AR, which has been a hindrance to the introduction of sutureless valve prostheses in Europe. We investigated the effects and postoperative complications of 12 patients with a pure severe AR undergoing SU-AVR using Perceval. All patients were diagnosed with symptomatic pure AR. Purpose AR is the product of pure AR, as shown by our experiences with SU-AVR. SU-AVR in severe AR has a great chance of minimizing hospital cost and potentially lowering hospital cost without compromising the postoperative outcomes and in-hospital length of stay, as a result of the surgical procedure's outstanding technical results and stellar hemodynamics.

Concomitant mitral regurgitation in patients with low-gradient aortic stenosis: an analysis from the German Aortic Valve Registry.

Background Patients with severe aortic stenosis often suffered with mitral regurgitation, which may be difficult with standard echocardiographic measurements of mean pressure gradient, flow velocity, and aortic valve area. Aims Herein We investigated the prevalence and severity of MR in patients with severe AS, as well as its effect on the accuracy of AS measurement's standard echocardiographic parameters. Methods This report included 119,641 patients with severe AS in the German Aortic Registry from 2011 to 2017. Results Overall, 78,890 patients with mild to moderate t-moderate and 4262 with severe MR were compared to 37,489 patients without MR. Patients with mild-to-moderate and severe MR had significantly lower mPG, which increased with LVEF impairment.
