BACKGROUND D-transposition of the great arteries (TGA) with left ventricular outflow tract obstruction (LVOTO) may be treated with arterial switch operation (ASO) with or without LVOT intervention, as well as non-ASO anatomic repairs, such as aortic translocation or Rastelli procedure. We evaluated midterm results of repair for TGA/LVOTO at our institution. METHODS AND RESULTS Eighty-eight pa...

Atrial fibrillation (AF) has been reported to be an important prognostic indicator for clinical deterioration particularly in patients with hypertrophic obstructive cardiomyopathy (HOCM). A 66-year-old female complained of severe exertional dyspnea and tachycardia, which were resistant to medical treatments. Doppler echocardiography demonstrated a peak left ventricular outflow tract (LVOT) grad...

AIMS Several methods are used to induce latent left ventricular outflow tract (LVOT) gradients in patients with hypertrophic cardiomyopathy (HCM). We compared LVOT gradients induced by Valsalva manoeuvre (VM) and exercise echocardiography (EE) in patients with HCM treated with percutaneous transluminal septal myocardial ablation (PTSMA). METHODS AND RESULTS Left ventricular outflow tract grad...

INTRODUCTION Partial resection of the septal muscle is a well-established and effective method of surgical treatment for patients with hypertrophic obstructive cardiomyopathy (HOCM). The procedure is characterized by a low operative mortality rate and long-term clinical improvement that has been confirmed in numerous publications. Mitral insufficiency in patients with HOCM is mostly functional ...

The study was conducted to evaluate the surgical results in patients with hypertrophic obstructive cardiomyopathy (HOCM) who underwent either classic Morrow septal myectomy or modified procedure.The modified Morrow septal myectomy has gained interest as a new treatment for patients with drug-refractory symptoms of HOCM; however, its benefits in comparison to the classic procedure are unknown.In...

BACKGROUND Hypertrophic obstructive cardiomyopathy (HOCM) is characterised by asymmetric myocardial hypertrophy, which is most pronounced in the interventricular septum (IVS) and is responsible for the dynamic obstruction of the left ventricular outflow tract (LVOT). Successful alcohol septal ablation (ASA) of the IVS allows to reduce the thickness of the parabasal part of the IVS myocardium an...

BACKGROUND Congenital subaortic stenosis (SAS) has a high recurrence rate after surgical correction. Aortic valve disease frequently coexists with SAS, being its occurrence and progression unpredictable. We aimed to assess predictors of SAS recurrence and aortic valve disease occurrence and progression. METHODS Retrospective analysis of 51 patients with SAS followed in a congenital heart dise...

We present the case of a previously fit 84-year-old female with long-standing systemic hypertension and the echo phenotype of hypertrophic cardiomyopathy (HCM) - asymmetrical septal hypertrophy, significant resting left ventricular (LV) outflow obstruction and mitral regurgitation (MR) secondary to systolic anterior motion (SAM) of the mitral valve. Valsalva provocation caused an increase in LV...

OBJECTIVES The aim was to assess the early and mid-term clinical effects of transaortic extended septal myectomy (TAESM) on obstructive hypertrophic cardiomyopathy (HCM) in China. METHODS Ninety-three consecutive patients [57 men; mean age 45.8 ± 13.4 (11-74) years] with obstructive HCM underwent TAESM in Fuwai hospital. Their clinical data were analysed retrospectively. All the patients had ...

Hypertrophic obstructive cardiomyopathy (HOCM) is a common genetic cardiovascular disease that can lead to significant morbidity and mortality. Patients with HOCM often present with symptoms of dyspnea, angina, syncope, and heart failure, which can be refractory to medical therapy. An alternative approach is alcohol septal ablation (ASA). This minimally invasive treatment has gradually gained a...
