Surgical Repair of Ventricular Septal Defect Following Transcatheter Aortic Valve Implantation: A Case Report.
This case report describes the rare occurrence of a ventricular septal defect (VSD) after transcatheter aortic valve implantation (TAVI) in an 88-year-old male patient with aortic stenosis and other comorbidities. Initially asymptomatic, the patient was discharged but readmitted 2 weeks later with decompensated heart failure. ⋯ A bovine pericardial patch was successfully used for repair. This case highlights the importance of vigilant post-TAVI monitoring and individualized treatment for TAVI-related complications.

Central neurogenic hyperventilation (CNH) is a rare disease, caused by chemical or mechanical disturbance of respiratory centers. It is characterized by the absence of extracerebral respiratory stimuli. A woman developed severe respiratory alkalosis and lactatemia after resection of a posterior fossa meningioma despite lack of cardio-respiratory or metabolic alterations. ⋯ Treatment with mannitol and dexamethasone reestablished normal breathing patterns. Lactatemia was likely due to reduced splanchnic lactate utilization. Intracranial pathologies should be suspected in case of hyperventilation without overt reasons. cCT to confirm edema or ischemia and prompt treatment is suggested.

Awake combined spinal caudal anesthesia has been used as an anesthetic technique for longer-duration infraumbilical surgeries in infants. Literature on the safety and feasibility of this technique is limited. We share our experience with 27 infants undergoing longer-duration urologic surgery using awake combined spinal and caudal anesthesia without the use of systemic sedatives or inhalational agents. We describe our technique, safety considerations, and details surrounding the optimal timing of caudal catheter activation for prolongation of surgical anesthesia.
