Early Improvement in Mitral Regurgitation after Cardiac Resynchronization Therapy in Cardiomyopathy Patients.

Early Improvement in Mitral Regurgitation after Cardiac Resynchronization Therapy in Cardiomyopathy Patients. J Heart Valve Dis. 2017 Sep;26(5):557-563 Authors: Sadeghian H, Lotfi-Tokaldany M, Montazeri M, Kazemi Saeed A, Sahebjam M, Sardari A, Ejmalian G Abstract BACKGROUND: The study aim was to investigate factors affecting the improvement of mitral regurgitation (MR) severity within 48 hours after cardiac resynchronization therapy (CRT) in patients with cardiomyopathy. METHODS: Sixty-nine cardiomyopathy patients (48 males, 21 females; mean age 59.12 ± 9.66 years) in NYHA functional class ≥III, with left ventricular ejection fraction (LVEF) ≤35%, and QRS duration>120 ms, with MR ≥moderate, were included in the study. Conventional echocardiography was performed before and within 48 h after CRT, and all patients underwent tissue Doppler imaging prior to CRT. Improved MR was defined as a reduction of at least one grade in MR severity. RESULTS: After CRT, 49 patients (71%) showed MR improvement but 20 (29%) had no MR improvement. The mean MR severity grade was reduced significantly, from 2.70 ± 0.77 before CRT to 1.90 ± 0.94 after CRT (p

Results from trials of both Medtronic‘s (NYSE:MDT) and Edwards Lifesciences‘ (NYSE:EW) transcatheter aortic valve replacement systems exploring their use in low-risk patients indicated that the devices were as safe as open surgery, paving the way for possible new indications for TAVR technology. Data from the trials were presented over the weekend at the American College of Cardiology 68th Annual Scientific Session 2019 in New Orleans and simultaneously published in the New England Journal of Medicine. Currently, TAVR devices are only approved by the FDA for treating severe aortic valve stenosis in patients at ...

man K Abstract Dilated cardiomyopathy produces abnormal left ventricular (LV) blood flow patterns that are linked with thromboembolism (TE). We hypothesized that implantation of mechanical heart valves non-trivially influences TE risk in these patients, exacerbating abnormal LV flow dynamics. The goal of this study was to assess how mitral valve design impacts flow and hemodynamic factors associated with TE. The mid-plane velocity field of a silicone dilated LV model was measured in a mock cardiovascular loop for three different mitral prostheses, two with multiple orientations, and used to characterize LV vortex ...

AbstractTransvalvular leakage (TVL) of a prosthetic heart valve is not negligible regurgitant flow in patients with critically low contractile function. Although the opening function of prosthetic valves has been reported, its closing function is not well understood. A man in his 70  s had a history of mitral valve replacement (MVR) with a Magna Mitral® valve for ischemic mitral valve regurgitation. He presented with dyspnea 2 years postoperatively. Echocardiography showed moderate TVL. The pulmonary capillary wedge pressure and cardiac index were 37 mmHg and 1.65 L/min/m2, respectively. Because we consi...

It is needless to say that heart disease in pregnancy is a challenge for the obstetrician and the cardiologist. Hemodynamic changes in pregnancy and labour can adversely affect many of the significant cardiac lesions. Increase in blood volume and heart rate are the important factors during pregnancy. In general stenotic lesions and pulmonary hypertension are poorly tolerated, while regurgitant lesions are better tolerated. Specific risks like aortic dissection and rupture are there for coarctation of aorta. Several risk stratification schemes have been developed for assessing the risk of pregnancy with heart disease over ...

Authors: Jung W, Hajredini B, Zvereva V Abstract The general rules for participation in road traffic are specified in the German Driving License Regulations (FeV). The assessment of fitness to drive motor vehicles is, in addition to Annex 4 of the FeV, governed by the guidelines of the German Federal Highway Research Institute, which implements the requirements of the European Union in Germany. By anchoring the assessment guidelines on fitness to drive in the FeV (Annex 4) and the publication in the Traffic Journal, the guidelines have a normative character. On 28 December 2016 the 11th amendment of ...

Rescue TAVI for Aortic Regurgitation after Left Ventricular Assist Device Implantation Following Preoperative Impella® Support. J Heart Valve Dis. 2017 Sep;26(5):603-605 Authors: M Herrmann FE, Wellmann P, von Dossow V, Massberg S, Hagl C, Schramm R, Pichlmaier M Abstract A patient presented with a decompensated cardiomyopathy requiring invasive hemodynamic support with an Impella® heart pump. Extracorporeal life support (ECLS) became necessary during the further course and the patient was bridged to left ventricular assist device (LVAD) implantation. Postoperatively, the patient did not improv...
