Transcatheter treatment of heart valve disease is well established today. However, for the treatment of tricuspid regurgitation (TR), no effective catheter-based approach is available. Herein, we ...report the first human case description of transcatheter treatment of severe TR in a 79-year-old patient with venous congestion and associated non-cardiac diseases. In this patient, surgical treatment had been declined and pharmacological therapy had been ineffective. After ex vivo and animal studies, the treatment of TR was performed by percutaneous caval valve implantation.
In a transcatheter approach through the right femoral vein, a custom-made self-expanding heart valve was implanted into the inferior vena cava (IVC). The device was anchored in the IVC at the cavoatrial junction with the level of the valve aligned immediately above the hepatic inflow and protruding into the right atrium. After deployment, excellent valve function was observed resulting in a marked reduction in caval pressure and an abolition of the ventricular wave in the IVC. Sequential echocardiographic exams over a follow-up period of 8 weeks confirmed continuous device function without paravalvular leakage or remaining venous regurgitation. The patient experienced improved physical capacity and was able to resume off-bed activities. There was no recurrence of right heart failure during follow-up and a partial reduction of ascites. The patient was discharged from hospital into a rehabilitation programme.
Transcatheter treatment of severe TR by caval valve implantation is feasible resulting in an immediate abolition of IVC regurgitation and mid-term clinical improvement. Thus, in selected non-surgical patients, caval valve implantation may become a therapeutic option to treat venous regurgitation and improve associated non-cardiac diseases. Further confirmatory experience with longer follow-up is required to evaluate the long-term clinical benefit of the procedure as well as potential deleterious effects.
Data on the prevalence of depression and anxiety in elderly cardiovascular disease patients are limited and there are only few studies focussing on treatment effects. Thus, the current study aimed to ...analyse elderly patients suffering from aortic stenosis (AS) and undergoing transcatheter aortic valve replacement (TAVR) with respect to both, prevalence rates before TAVR and dynamics in the clinical course.
The study included 140 AS patients undergoing TAVR (77.8 ± 7.7 years, 42.9% male, mean STS-Score 4.4 ± 2.2). Detailed clinical, laboratory and functional analysis was performed. In addition, quality of life (EQ-5D, EQ VAS), clinical frailty (CFS) and anxiety/depression (HADS-D), was assessed at baseline, 6 weeks, 6 months and 12 months after TAVR.
Before TAVR, HADS-D revealed ≥8 points for anxiety and/or depression in 54 patients (38.6%), depression in 33 patients (23.6%) and for anxiety in 40 patients (28.6%). In the group showing HADS-D ≥8 points for anxiety, there was an improvement already 6 weeks after TAVR for anxiety (p < 0.05) but not for depression. In the group showing HADS-D ≥8 points for depression, there was a significant improvement at the 6 weeks' follow-up for both, depression (p < 0.001) and anxiety (p = 0.012) remaining stable for depression but not for anxiety until 12 months after TAVR.
TAVR leads to reductions of depression and anxiety in patients showing pathologic baseline values in HADS-D. There were no associations between pre-existing depression and anxiety with long-term mortality in our study.
•There are high prevalence rates of depression and anxiety in elderly AS patients.•TAVR leads to reductions of pre-existing depression and anxiety.•There were no associations between depression and anxiety with long-term mortality.•The HADS-D is valuable and sensitive to assess mental health in AS patients.
A patent foramen ovale (PFO) persists in about one-quarter of people and is the source of up to 25% of all ischemic strokes, especially strokes in young adults. PFO can be easily diagnosed by ...transthoracic contrast and/or transesophageal echocardiography. Interventional closure of the PFO via the femoral vein is a commonly used cardiological procedure since several trials have demonstrated the superiority of PFO closure over standard medical therapy in patients with PFO and who have experienced post ischemic, cardioembolic, or cryptogenic stroke. The current paper and video show the procedure of PFO closure in a step-by-step manner.
Biventricular (BV) pacing is an established therapy for heart failure (HF) patients with intraventricular conduction delay, but not all patients improved clinically. We investigated the ...interventricular delay (IVD) by means of the transesophageal left ventricular posterior wall potential (LVPWP).
A total of 18 HF patients (age 62+/-9 years; 15 males) with NYHA class 3.1+/-0.3, LV ejection fraction 22+/-7%, left bundle branch block and a QRS duration (QRSD) of 171+/-27 ms were analyzed using transesophageal LVPWP before implantation of a BV pacing device. The median follow up was 14+/-14 months. In 14 responders, IVD was 81+/-25 ms with a QRSD/IVD ratio of 2.2+/-0.3 with reclassification of NYHA class 3.1+/-0.3 to 2.0+/-0.5 (p<0.001) and an increase in LV ejection fraction from 22+/-7% to 36+/-11% (p=0.001) during long-term BV pacing. In four non-responders, transesophageal IVD was significantly smaller at 30+/-11 ms (p=0.001).
Transesophageal IVD may be a useful method to detect responders to BV pacing. Transesophageal LVPWP may be a simple and useful technique to detect clinical responders to BV pacing in HF patients.
Aside from enteroviruses and other viruses, e.g., adenoviruses, which are known to be associated with idiopathic dilated cardiomyopathy (IDC), a cardiac tropism is also attributed to parvovirus B19 ...(PVB19). The purpose of the present study was to determine the prevalence of enterovirus, adenovirus and PVB19 genomes in the myocardium of adult patients with IDC and to analyze the significance of PVB19 with regard to the course of the disease, as compared to the other cardiotropic viruses. In 52 adult patients with IDC and 10 control patients with normal left ventricular ejection fraction (> or =55%) undergoing coronary artery bypass surgery, myocardial tissue samples were investigated for enteroviral RNA using polymerase chain reaction (PCR) and Southern blot hybridization of the PCR product. Specific nested PCR was used to assess the prevalence of adenovirus and PVB19 DNA, in addition to sequencing of the latter. The clinical and echocardiographic course of the disease was followed for a mean (+/- SD) period of 21.1+/-9.5 months. Fourteen of the 52 patients (27%) were enterovirus-positive, 2/52 (4%) patients were adenovirus-positive, 14/52 (27%) patients were PVB19-positive, 8/52 (15%) patients were enterovirus plus PVB19-positive, and in 14/52 (27%) patients no viral genomes were found. Six patients died during the follow-up period, without any significant difference between the patient groups: 1/14 (7%) in the enterovirus-positive, 0/2 (0%) in the adenovirus-positive, 2/14 (14%) in the PVB19-positive, 1/8 (12.5%) in the enterovirus plus PVB19-positive, and 2/14 (14%) in the virus-negative group. PVB19 genome was found in 4 of the 10 (40%) control patients, but no enterovirus or adenovirus genomes were detected in these patients. In conclusion, in the myocardium of patients with IDC, PVB19 is detectable as frequently as enteroviral genome. PVB19-positive patients with IDC have a rather favorable prognosis and do not differ significantly from the other virus-positive or virus-negative patient groups with respect to survival. Finally, the pathogenetic and prognostic significance of PVB19 in IDC still remains unclear.
The purpose of this study was to evaluate termination of atrial flutter (AFL) by directed rapid transesophageal atrial pacing (TAP) with and without simultaneous transesophageal echocardiography ...(TEE) performed using a novel TEE tube electrode.
A total of 16 AFL patients (age 63+/-12 years; 13 males) with mean AFL cycle length of 224+/-24 ms (n=12) and mean ventricular cycle length of 448+/-47 ms (n=12) were analyzed using either an esophageal TO electrode (n=10) or a novel TEE tube electrode consisting of a tube with four hemispherical electrodes that is pulled over the echo probe (n=6). AFL could be terminated by directed rapid TAP using an esophageal TO electrode, leading to induction of atrial fibrillation (AF) (n=6), induction of AF and spontaneous conversion to sinus rhythm (SR) (n=3), and with conversion to SR (n=1). AFL could also be terminated by directed rapid TAP using the TEE tube electrode, with induction of AF (n=3) or induction of AF and spontaneous conversion to SR (n=3).
AFL can be terminated by directed rapid TAP with hemispherical electrodes with and without simultaneous TEE. TAP with the directed TEE tube electrode is a safe, simple, and useful method for terminating AFL.
