Summary
Monitored anesthesia care (MAC) for transcatheter aortic valve replacement (TAVR) reduces operating room time, length of stay, and 180-day mortality compared to general anesthesia (GA). Costs were not significantly different between the two anesthesia methods.
Area of Science:
- Cardiology
- Anesthesiology
- Health Services Research
Background:
- Monitored anesthesia care (MAC) is increasingly replacing general anesthesia (GA) for transcatheter aortic valve replacement (TAVR).
- Comparative outcome data between MAC and GA for TAVR are essential for clinical decision-making.
Purpose of the Study:
- To compare clinical outcomes and in-hospital costs of MAC versus GA for TAVR.
- To evaluate the efficiency and safety of MAC in TAVR procedures.
Main Methods:
- A single-center retrospective review of 349 patients undergoing transfemoral TAVR from 2014 to 2019.
- Data collected included operating room time, intensive care unit and total length of stay, and costs.
- Propensity matching was used to create 83 comparable pairs of patients (MAC vs. GA).
Main Results:
- MAC TAVR was associated with significantly reduced operating room time, ICU length of stay, and total hospital length of stay in both unmatched and propensity-matched cohorts.
- Propensity-matched MAC TAVR patients demonstrated a significant reduction in 180-day mortality (2.4% vs. 12%).
- No significant differences were observed in total hospitalization cost or overall total cost between MAC and GA groups.
Conclusions:
- Transcatheter aortic valve replacement performed with monitored anesthesia care offers improved operating room efficiency and reduced length of stay.
- Monitored anesthesia care is associated with a significant decrease in 180-day mortality for TAVR patients.
- While MAC improves efficiency and reduces mortality, it does not significantly impact overall costs compared to general anesthesia.

Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
