Septal myectomy safe for hypertrophic cardiomyopathy

11 Jul 2020
At least a dozen children have infected incisions, after undergoing heart surgery at the hospital – allegedly from contaminated equipment.

Septal myectomy is a safe procedure, bearing minimal risk of early mortality and adverse events, a recent study has found.

The researchers conducted a prospective analysis on 345 patients (mean age, 55.0±13.4 years; 44.9 percent male) with hypertrophic cardiomyopathy who underwent treatment via surgical myectomy. The primary study endpoint was 30-day mortality, while other outcomes of interest included long-term survival and freedom from sudden cardiac death and recurrent atrial tachyarrhythmia.

One male and five female patients died within 30 days of surgery, yielding a short-term mortality rate of 1.7 percent. Most of these patients were above 60 years of age, save for one, who was aged 58 years. Logistic regression analysis did not find any predictor of 30-day mortality.

Thirteen patients (3.8 percent) developed acute renal failure, while nine (2.6 percent) had bleeding that required revision. There were six (1.7 percent) cases of postoperative pericarditis that needed pericardiocentesis. Twenty-nine patients needed permanent pacemakers implanted after surgery.

Almost all (95.4 percent; n=329) of the participants were still able to attend the last follow-up assessment, at which time most of them (77.2 percent; n=254) were categorized as being of the New York Heart Association class I. At 38 months of follow-up, 97.0±1.0 percent of patients attained freedom from all-cause death.

Seven late-term deaths were reported, and the 5-year overall long-term survival rate after myectomy was 95.7±1.7 percent. This was not significantly different than in age- and sex-matched general-population controls (p=0.109).
