“…Compared with the high mortality rates (6%-10%) reported among the pregnant women with untreated MS, 39,40 resolve over time or reduce in size. 18,24,26,27,29,36 Minimal fluoroscopy time with a shorter inflation/deflation cycle and the use of lead shields has minimized the radiation exposure to the fetus, making the procedure safer. Although the majority of the reported studies used the Inoue technique, which helps to limit the fluoroscopic time, few studies reported the use of Joseph mitral valvuloplasty balloon catheter (JOMIVA) by over the wire technique.…”

Introduction The objective of this study was to systematically review the maternal and fetal outcomes in pregnant women who underwent percutaneous balloon mitral valvuloplasty (PBMV) during pregnancy. Material and methods A search was conducted on MEDLINE and Embase databases to identify studies published between 2000 and 2018 that reported on maternal and fetal outcomes following PBMV performed in pregnancy. Randomized controlled trials, cohort studies, case‐control studies, cross‐sectional studies and case series with four or more pregnancies in which PBMV was performed during pregnancy were included. Reference lists from relevant articles were also hand‐searched for relevant citations. A successful procedure was defined as one where there was a reported improvement in the valve area or reduction in the mitral valve gradient. A random effects model was used to derive pooled estimates of various outcomes and the final estimates were reported as percentages with a 95% confidence interval (95% CI). Results Twenty‐one observational studies reporting 745 pregnancies were included in the review, all of them having reported outcomes without a comparison group. Most of the studies fell into the low‐risk category as determined using the Joanna Briggs Institute (JBI) critical appraisal checklist for case series. Most of the studies (86%) were reported from low‐ to middle‐income countries and PBMV was mostly performed during the second trimester of pregnancy. Forty‐three procedures (5.7%) were unsuccessful, nearly half (n = 19) of them reported among women with the severe subvalve disease (Wilkins subvalve score 3 or more). There were 11 maternal deaths among those with suboptimal valve anatomy (severe subvalve disease or Wilkin score >8). Mitral regurgitation was the most common cardiac complication (12.7%; 95% CI 7.3%‐19.1%), followed by restenosis (2.4%; 95% CI 0.02%‐7.2%). Pooled incidence of cesarean section was 12.1% (95% CI 3.6%‐23.8%), preterm delivery 3.9% (95% CI 0.6%‐9.0%), stillbirth 0.9% (95%CI 0.2%‐2.2%) and low birthweight 5.4% (95% CI 0.2%‐14.7%). Conclusions PBMV may be an effective and safe procedure for optimizing outcomes in pregnant women with mitral stenosis in the absence of severe subvalve disease.

“…[191] ES was also found having positive effects on alopecia cue to electrotrichogenesis, which could enhance the influx of calcium ions into the dermal papilla cells via voltage-gated transmembrane ion channels, facilitate ATP synthesis in mitochondria, activate protein kinases, and stimulate protein synthesis and cell division. [192][193][194] Based on the proven therapeutic effects of traditional ES on hair growth, Yao et al fabricated a universal motion-activated ES device (m-ESD) that could effectively promote hair regeneration via random body motions. [195] Similar to the wound healing bandage, the m-ESD also consisted of two modules, including an omnidirectional TENG acting as the electric pulse generator and a pair of interdigitated dressing electrode providing spatially distributed electric fields (Figure 7b).…”

Wearable and implantable electroceuticals (WIEs) for therapeutic electrostimulation (ES) have become indispensable medical devices in modern healthcare. In addition to functionality, device miniaturization, conformability, biocompatibility, and/or biodegradability are the main engineering targets for the development and clinical translation of WIEs. Recent innovations are mainly focused on wearable/implantable power sources, advanced conformable electrodes, and efficient ES on targeted organs and tissues. Herein, nanogenerators as a hotspot wearable/implantable energy-harvesting technique suitable for powering WIEs are reviewed. Then, electrodes for comfortable attachment and efficient delivery of electrical signals to targeted tissue/organ are introduced and compared. A few promising application directions of ES are discussed, including heart stimulation, nerve modulation, skin regeneration, muscle activation, and assistance to other therapeutic modalities.

“…Percutaneous mitral balloon valvuloplasty (MBV) is an effective therapeutic choice for suitable cases [5]. The MBV is ever effective in unsuitable situations for surgery [6]. The LA dysfunctions in mitral stenosis (MS) and subsequent recovery following successful MBV have been documented by conventional echocardiographic methods [4,7].…”

A Ai im m: : To evaluate LA functions after MBV using colour tissue Doppler imaging. M Ma at te er ri ia al l a an nd d m me et th ho od ds s: : Sixty-eight patients (58 females, mean age: 38 ±12 years) were included in the study. Within 24 h before MBV, all the patients underwent colour tissue Doppler study in addition to routine conventional echocardiographic examinations. Late diastolic velocities (A') measured at the LA wall adjacent to the septal and lateral annuli were recorded. All the measurements were repeated 24 h after MBV. The MBV was done using the Inoue technique. Successful MBV patients were included in group A and those who developed severe mitral regurgitation (MR) were included in group B.R Re es su ul lt ts s: : Sixty-one patients underwent successful MBV while 7 developed MR. Mitral valve areas (MVA) in both groups were significantly increased. Maximum and mean gradients, LA diameter, systolic pulmonary arterial pressure and mean LA pressures were decreased while septal and lateral A' were significantly increased in group A. In group B, no significant change in any variable was found except for the increase in MVA.C Co on nc cl lu us si io on ns s: : After successful MBV, increase in A' velocity was seen in parallel to the recovery of LA functions. Early improvements in left atrial systolic functions after successful MBV can easily be determined by colour tissue Doppler as a quick and reliable method. K Ke ey y w wo or rd ds s: : mitral stenosis, valvuloplasty, left atrial functions, tissue Doppler echocardiography S t r e s z c z e n i e W Ws st tę ęp p: : W standardowych badaniach echokardiograficznych wykazano, że po skutecznym zabiegu przezskórnej komisurotomii mitralnej (PKM) dochodzi do istotnej poprawy funkcji lewego przedsionka.C Ce el l: : Ocena funkcji lewego przedsionka po PKM przy użyciu badania kolorowego dopplera tkankowego. M Ma at te er ri ia ał ł i i m me et to od dy y: : Do badania włączono 68 pacjentów (58 kobiet, średni wiek 38 ±12 lat). U wszystkich pacjentów, oprócz standardowego badania echokardiograficznego, wykonano badanie metodą dopplera tkankowego w ciągu 24 godzin przed zabiegiem PKM. Rejestrowano prędkość późnorozkurczową (A') mierzoną w ścianie lewego przedsionka przylegającej do przegrodowej i bocznej części pierścienia. Wszystkie pomiary powtórzono po 24 godzinach od PKM. Badanie to wykonano według techniki Inoue. Pacjentów, u których wykonano skuteczny zabieg PKM, włączono do grupy A. Osoby, u których po zabiegu wystąpiła ciężka niedomykalność zastawki mitralnej (ang. mitral regurgitation, MR), włączono do grupy B.W Wy yn ni ik ki i: : Skuteczne badanie PKM wykonano u 61 pacjentów, a u 7 osób wystąpiła MR. Pole powierzchni zastawki mitralnej (ang. mitral valve area, MVA) wzrosło istotnie w obu grupach. W grupie A zaobserwowano redukcję maksymalnego i średniego gradientu, wymiaru lewego przedsionka, skurczowego ciśnienia w tętnicy płucnej i średniego ciśnienia w lewym przedsionku oraz wzrost prędkości przegrodowej i bocznej (A'). W grupie B nie zaobserwowano i...
