Key points for anesthetic and hemodynamic management for patients with mitral stenosis

Key points for anesthetic and hemodynamic management for patients with mitral stenosis
Hemodynamic goals Avoid Monitor Intervention
Sinus rhythm Avoid atrial fibrillation or other SVT 5-lead ECG Manage new-onset atrial fibrillation or other SVT:
  • HR control
  • Cardioversion, if appropriate, for hemodynamic compromise (if no evidence of LA thrombus)
Slow to normal HR (50 to 70 bpm)

Avoid tachycardia

Avoid severe bradycardia <50 bpm

5-lead ECG

Pulse oximetry with visible waveform

Prevent pain-induced tachycardia by ensuring adequate anesthetic depth and effective analgesia

Manage tachycardia related to hypotension with phenylephrine (or norepinephrine)

Decrease HR with beta blockers if necessary
Maintain afterload

Avoid hypotension

Avoid sympathectomy (eg, spinal anesthesia)
Intra-arterial BP for major surgical procedures Administer a vasoconstrictor (eg, phenylephrine, norepinephrine) to manage hypotension
Adequate preload Avoid hypervolemia

Clinical course and oxygenation

Development of flash pulmonary edema (may present as acute coughing and hypoxemia in an awake patient)
Management of pulmonary edema: treat hypoxemia related to pulmonary edema immediately with 100% oxygen, PEEP, and, if necessary, intubation and controlled ventilation
Avoid hypovolemia Assess clinical response to fluid boluses

Maintain intravascular volume status

Rapid resuscitation for hemorrhage
Maintain RV contractility Avoid doses of drugs that cause significant myocardial depression Hemodynamics If inotropic support is needed, milrinone or dobutamine may be used if SVR and systemic BP are maintained; low-dose epinephrine may be necessary
Minimize PVR (optimize oxygenation and ventilation)

Avoid hypoxemia

Avoid hypercarbia

Pulse oximetry with visible waveform

Capnometry (end-tidal CO2)

ABG analysis if an intra-arterial catheter is in place
Minimize risk of hypoxemia and hypercarbia by:
  • Administering supplemental oxygen
  • Ensuring adequate ventilation
SVT: supraventricular tachyarrhythmia; ECG: electrocardiogram; HR: heart rate; LA: left atrial; bpm: beats per minute; BP: blood pressure; PEEP: positive end-expiratory pressure; RV: right ventricular; SVR: systemic vascular resistance; PVR: pulmonary vascular resistance; CO2: carbon dioxide; ABG: arterial blood gas.
