Long-Term Outcome of Alcohol Septal Ablation for Obstructive Hypertrophic Cardiomyopathy in the Young and the Elderly.

Objectives: The aim of this study was to compare outcomes of alcohol septal ablation (ASA) in young and elderly patients with obstructive hypertrophic cardiomyopathy (HCM).

Background: The American College of Cardiology Foundation/American Heart Association guidelines reserve ASA for elderly patients and patients with serious comorbidities. Information on long-term age-specific outcomes after ASA is scarce.

Effect of alcohol dosage on long-term outcomes after alcohol septal ablation in patients with hypertrophic cardiomyopathy.

Objectives: The aim of this study is to assess the long-term effects of alcohol dosage in alcohol septal ablation (ASA) on mortality and adverse arrhythmic events (AAE).

Background: ASA can be performed to reduce left ventricular outflow tract (LVOT) obstruction in patients with hypertrophic cardiomyopathy (HCM). However, the effect of alcohol dosage on long-term outcomes is unknown.

Basal infarct location but not larger infarct size is associated with a successful outcome after alcohol septal ablation in patients with hypertrophic obstructive cardiomyopathy: a cardiovascular magnetic resonance imaging study.

Alcohol septal ablation (ASA) is successful in most but not in all patients with obstructive hypertrophic cardiomyopathy (HCM). We therefore sought to investigate the relation between infarct location versus infarct size with outcome after ASA in patients with obstructive HCM. Baseline characteristics, procedural characteristics, and cardiovascular magnetic resonance findings at baseline and 4-6 month follow-up after ASA were analysed in 47 patients with obstructive HCM in a single-center retrospective study.

Additive value of dobutamine stress echocardiography in patients with an anomalous origin of a coronary artery.

An anomalous origin of a coronary artery (AOCA) is the second most common cause of non-traumatic sudden cardiac death in young athletes. Patients with a malignant course of an AOCA of the right coronary artery only need surgical correction when myocardial ischaemia is detected. An AOCA and its malignant or benign course can be detected by coronary angiography, coronary computed tomography or cardiac magnetic resonance imaging.

Long-term outcomes after medical and invasive treatment in patients with hypertrophic cardiomyopathy.

Objectives: The aim of this study was to determine the long-term outcomes (all-cause mortality and sudden cardiac death [SCD]) after medical therapy, alcohol septal ablation (ASA), and myectomy in patients with hypertrophic cardiomyopathy (HCM).

Background: Therapy-resistant obstructive HCM can be treated both surgically and percutaneously. But there is no consensus on the long-term effects of ASA, especially on SCD.

Periprocedural complications and long-term outcome after alcohol septal ablation versus surgical myectomy in hypertrophic obstructive cardiomyopathy: a single-center experience.

Objectives: This study compared alcohol septal ablation (ASA) and surgical myectomy for periprocedural complications and long-term clinical outcome in patients with symptomatic hypertrophic obstructive cardiomyopathy.

Background: Debate remains whether ASA is equally effective and safe compared with myectomy.

Methods: All procedures performed between 1981 and 2010 were evaluated for periprocedural complications and long-term clinical outcome.
