Summary
Urgent alcohol septal ablation (ASA) improved hemodynamics in a patient with hypertrophic obstructive cardiomyopathy (HOCM) and sepsis. This intervention relieved obstructive shock, enhancing cardiovascular stability despite a fatal outcome.
Area of Science:
- Cardiology
- Interventional Cardiology
- Critical Care Medicine
Background:
- Hypertrophic obstructive cardiomyopathy (HOCM) can lead to severe hemodynamic compromise.
- Sepsis can exacerbate the obstructive shock associated with HOCM.
- Management of HOCM in the context of sepsis presents unique challenges.
Observation:
- A 69-year-old male with known HOCM presented with progressive hypoxemia and sepsis.
- The patient required cardiopulmonary resuscitation and mechanical ventilation due to hemodynamic instability.
- Despite vasopressors and colloids, the patient remained unstable, suggesting a combined distributive and obstructive shock.
Findings:
- An urgent alcohol septal ablation (ASA) was performed to address the obstructive component of shock.
- Immediately following ASA, the left ventricular outflow tract gradient resolved.
- Hemodynamic parameters, including mean arterial pressure and oxygenation, significantly improved post-procedure.
Implications:
- Urgent ASA can be a life-saving intervention in hemodynamically unstable HOCM patients with sepsis.
- This case highlights the potential benefit of addressing obstructive shock in sepsis-induced distributive shock.
- Further research may explore the role of urgent septal reduction therapies in similar critical scenarios.

Disorders affecting blood volume, vascular tone, or vascular function can disrupt vascular homeostasis, including conditions like hypertension, hemorrhage, and shock.
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...

Pharmacologic intervention is crucial in treating cardiac arrest patients during ACLS or Advanced Cardiovascular Life Support. The ACLS algorithms guide the administration of specific drugs based on the patient's cardiac arrest rhythm, which includes pulseless ventricular tachycardia (VT), ventricular fibrillation (VF), asystole, and pulseless electrical activity (PEA).EpinephrineIndication: Epinephrine is the first-line drug for all cardiac arrest rhythms.Mechanism of Action: Epinephrine...

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
01:23Cardiopulmonary Resuscitation III: AED Use
Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...
01:28Cardiomyopathy VII: Pre and Post Operative Nursing Management
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...
