Long-Term Durability of Transcatheter Aortic Valve Prostheses

Background

Very little is known about long-term valve durability after transcatheter aortic valve replacement (TAVR).

Separation anxiety: Extreme dehiscence of a mitral annuloplasty ring

We report a patient admitted with acute pulmonary edema 3 months after mitral valve repair, with no history of inter‐current febrile illness. Transesophageal echocardiography (TEE) demonstrated severe mitral regurgitation (MR) and an abnormally positioned annuloplasty ring, suggestive of dehiscence. The extreme extent of ring dehiscence was visualized on 3‐dimensional TEE (3D), with near‐complete separation of the ring. Strept.Mitis and Cristatus were isolated from the ring following redo mitral valve surgery, confirming endocarditis as the mechanism for dehiscence. This report highlights the additive role and superior ability of 3D TEE in the identification and anatomic delineation of mitral ring dehiscence.     

Acute penetrating atherosclerotic ulcer of the ascending aorta

A 67‐year‐old man presented with chest pain. Clinical examination revealed hypertension (160/90 mm Hg). Electrocardiogram indicated no acute coronary syndrome and cardiac enzymes were normal. Catheterization was performed owing to the patient’s continuing chest pain and ascending aortogram revealed irregular aortic wall. A computed tomography image showed the shape of penetrating ulcer. The patient was taken to the operating room and intraoperative examination confirmed the diagnosis of penetrating atherosclerotic ulcer (PAU). Coronary artery bypass graft and bovine pericardial patch repair of PAU was performed. A bovine pericardial patch was done as aortic root was heavily calcified and was easy to handle and more hemostatic.     

基于PDCA循环的过渡期护理对老年人瓣膜置换术后ICU出科时期的干预效果

目的探讨基于PDCA循环的过渡期护理对老年人瓣膜置换术后重症监护室（ICU）出科时期的干预效果。 方法选取2020年10月至2021年9月在遵义医科大学附属医院行瓣膜置换术的老年患者60例，其中30例在ICU出科过渡期采用常规护理（对照组），余30例采用基于PDCA循环的过渡期护理（观察组）。观察两组患者干预前后超声心动图相关指标左室射血分数（LVEF）和左心室舒张末期容积（LVEDV）、医院焦虑抑郁评分量表（HADS）评分、中文版Mishel疾病不确定感量表（MUIS）评分，以及日常生活能力评估量表（ADL）评分变化情况。计数资料的比较采用χ²检验，计量资料的比较采用t检验。 结果护理后，观察组LVEF和LVEDV指数均高于对照组（t=3.286、2.035，P<0.05），HADS-A、HADS-D和MUIS评分均低于对照组（t=3.873、3.873、6.076，P<0.01），ADL评分高于对照组（t=6.076，P<0.01）。 结论基于PDCA循环的过渡期护理可明显改善老年人瓣膜置换术后从ICU转入普通病房期间的焦虑情绪和疾病不确定感，促进心功能恢复，提高自理能力。     

Enhanced recovery (fast-track surgery) after total ankle replacement: The state of the art

The post-operative results of a total ankle replacement are not determined solely by an optimal surgical technique, but by an appropriate anesthesiological and rehabilitative post-operative approach. Enhanced functional recovery often depends on a multidisciplinary approach based on a correct framework of the patient and his needs, requests, and characteristics.Extensive bibliographical research has been performed on Pubmed, Google Scholar, Scopus.This comprehensive and inclusive review of the literature aims to examine the state of the art of “fast-track” protocols employed in total ankle replacement (TAR), considering pre-operative preparation, anesthetic management, intraoperative and surgical factors, post-operative rehabilitative care and reduction of hospitalization time.
