Surgical Myectomy

Background: In hypertrophic cardiomyopathy (HCM) with severe left ventricular outflow tract obstruction (LVOTO), surgical myectomy (SM) performed for relief of intractable symptoms is safe and associated with excellent long-term symptom-free survival. In such patients, we sought to determine if SM also results in improvement of long-term outcomes. Methods: We studied 1530 HCM patients with severe LVOTO (50±13 years, 63% men) that were evaluated at our center [excluding <18 years of age, LV ejection fraction (LVEF) <50%, LVOT gradient <30 mm Hg). Clinical, echocardiographic and surgical data were recorded. A composite endpoint of death and/or implantable defibrillator (ICD) discharge was recorded. Results: Hypertension, coronary artery disease (CAD), family history of HCM and syncope were present in 41%, 15%, 17% and 18%, while 73% patients were in Functional Class (FC) ≥ II. Mean LVEF, basal septal thickness, LVOT gradient (resting or provocable) and indexed left atrial dimensions were 62±5%, 2.2±1 cm, 101±39 mm Hg, 2.2±0.4 cm/m2. During 8±6 years of follow-up, 990 (65%) patients underwent SM (of which 65% were isolated SM), while 540 (35%) did not. 94 (6%) patients had alcohol septal ablation (66 in the non myectomy group), while 18% developed atrial fibrillation (AF), and 18% had ICD. There were 169 (11%) events (151 deaths), with 0% 30-day mortality in the SM group. On stepwise multivariable Cox Proportional Hazard analysis, increasing age (Hazard Ratio or HR 1.22 [1.06-1.40]), CAD (HR 1.57 [1.06-2.33]), worsening FC (HR 1.34 [1.05-1.71]) and AF (HR 1.73 [1.23-2.43]) predicted higher events, while SM as a time-dependent covariate (HR 0.58 [0.41-0.81]) was associated with improved event-free survival (all p<0.01). Kaplan-Meier curve showing impact of SM on outcomes is shown in Figure. Conclusion: In HCM patients with severe LVOTO, SM is associated with significant improvement in long-term outcomes when compared to watchful waiting.

Left Ventricular Outflow

Left ventricular outflow tract obstruction can occur at subvalvar, valvar, and supravalvar levels. Severity and progression can be evaluated by echocardiography. Aortic valve stenosis can usually be relieved by balloon valvotomy, but some patients require surgery, either with valvotomy, valve replacement, or the Ross procedure. Sub- and supravalvar aortic stenosis require surgical management. Long-term follow-up of all patients is required.
