Transfemoral Transcatheter Aortic Valve Implantation
Published in Theo Kofidis, Minimally Invasive Cardiac Surgery, 2021
Annular rupture is a potential life-threatening complication. Emergency pericardiocentesis followed by conversion to open surgery needs to be immediately performed to save the patient. Small aortic annulus size and heavy and eccentric calcification around the aortic annulus are associated with this complication. The oversized balloon-expandable valve and aggressive post-balloon dilatation are also considered risks.

An immediate postoperative complication is dysphagia, which, if sufficiently symptomatic, can be relieved with an early flexible endoscopy or, if not responding, by performing single balloon dilatation. Retching postoperatively can occur, particularly in children with neurological impairment. Complication management is similar to that described in “Open fundoplication: Complications.”
Malignant strictures of the biliary tree

After the wire, the guide catheter or stent inner tube is inserted. Difficulty at this stage suggests that there may be problems with the stent, and the cautious endoscopist may predilate the stricture with either an angioplasty-type balloon or a push dilator of graduated type. I find that predilatation is needed less than 5% of the time, but others use it much more frequently. Balloon dilatation is invariably painful and may induce violent reactions in a lightly sedated patient.

To further investigate the reliability and purity of our group characteristics, we excluded the cold steel dilatations 5/63 (8%) and submucosal resections 11/63 (17%) leaving subjects only treated with balloon dilatation 29/63 (46%) to be compared with CO2 laser 7/63 (11%). This revealed very similar results as when we include rigid dilatation and submucosal resection. Association between time to surgery and surgical method was not statistically significant in this case either (HR for balloon dilatation: 1.21, 95% CI: 0.75–1.97, p = .43). As expected, the surgical method variable did not pass the proportional hazards assumption test, indicating a violation of the assumption. The Cox PH regression was rerun using method as a stratification variable, and the resulting estimated survival functions are presented with approximate 95% confidence bands in Figure 3.

The cricopharyngeal (CP) muscle is located at the junction of the pharynx and oesophagus at the level of the sixth cervical vertebra and is a main part of the upper oesophageal sphincter (UES) [1]. As a common cause of dysphagia, cricopharyngeal achalasia (CPA) is defined as failure of the cricopharyngeus muscle to relax during the pharyngeal phase of swallowing [2], which may lead to many adverse clinical outcomes, including life-threatening aspiration pneumonia, dehydration, malnutrition, and mortality [3]. CPA occurs in various neuro-disorders, such as stroke, multiple sclerosis, primary muscle disorders, and Parkinson’s disease [4]. Patients with stroke, particularly brainstem lesions, have an increased risk of CPA [5–7]. Current interventions for CPA include routine rehabilitation treatment, electrical stimulation, balloon dilatation and transcervical cricopharyngeal myotomy (CPM) [8,9]. Balloon dilatation [9,10] involves mechanical expansion of the cricopharyngeal muscle, which causes obvious discomfort in patients, and it needs to be carried out repeatedly, which may lead to poor patient compliance. CPM [11,12] is effective for treating CPA but carries the risk of infection, salivary fistula formation and postoperative restenosis.

All patients were treated with balloon dilatation, stent-assisted angioplasty or balloon dilatation, and stent-assisted angioplasty. All surgeries were conducted by the same team according to the same protocol. Briefly, patients were set to the supine position. After anesthesia, the modified Seldinger method was used to perform the femoral artery puncture, and the catheter was sent to the lower end of abdominal aorta under the guide of a guidewire. Then, heparin sodium was intravenously injected, and a 0.018 guidewire was used to guide the balloon catheter. For stent-assisted angioplasty, the stent was release after balloon dilatation. Digital Subtraction angiography (DSA) was used to confirm the effects. A stenosis of <10% was considered as successful. After surgery, patients were treated with conventional therapy by alprostadil and antibiotics for one week. Aspirin and cilostazol were used for at least half a year after surgery. All patients were instructed to receive CTA at one and three months after surgery. The restenosis was defined as ≥50% restenosis at the original restenosis place.
