Left Ventricular Outflow

Hypertrophic cardiomyopathy (HCM) is an inherited myocardial disorder characterised by left ventricular hypertrophy. A subgroup of patients develops limiting symptoms in association with left ventricular outflow tract obstruction (LVOTO). Current international guidelines recommend that symptomatic patients are initially treated by alleviating exacerbating factors and negatively inotropic medication. Drug-refractory symptoms require a comprehensive evaluation of the mechanism of LVOTO and review by a multidisciplinary team to consider the relative merits of myectomy, alcohol septal ablation (ASA) and pacing. This article provides a brief overview of HCM and the pathophysiology of LVOTO, and reviews the use of ASA in patients with drug-refractory symptoms secondary to LVOTO.

Beach Chair

The haemodynamic response to the beach-chair position may be affected by the presence of left ventricular hypertrophy where remodelling of cardiac chambers can potentially lead to left ventricular outflow tract obstruction. We present a case report of severe hypotension in the beach-chair position, where focused cardiac ultrasound identified left ventricular hypertrophy and geometric features that contributed to the hypotensive response. This case illustrates that focused cardiac ultrasound has the potential to alert the clinician preoperatively to left ventricular outflow tract obstruction susceptibility during surgery in the beach-chair position, and intraoperatively to direct management should sudden decreases in blood pressure occur.

Left Ventricular Outflow

We describe a 57-year-old man with symptomatic severe aortic stenosis who underwent aortic valve reconstruction with glutaraldehyde-treated autologous pericardium with the Ozaki technique (Ozaki procedure). Seven months later, he rapidly developed progressive left ventricular hypertrophy with a left ventricular outflow tract obstruction. This required a reoperation for septal myectomy.
