Dynamic Left Ventricular Outflow Tract Obstruction Exacerbated by Thoracic Kyphosis.

ABSTRACT: We present a 74-year-old woman with kyphosis and symptoms of pre/syncope. Heart catheterization revealed dynamic left ventricular outflow tract obstruction (DLVOTO) with Brockenbrough Braunwald response only when kyphotic posture was assumed. She had a positive response to metoprolol. DLVOTO is a challenging diagnosis in the absence of resting LVOTO. (Level of Difficulty: Beginner.).

Unstable angina complicated with dynamic left ventricular outflow tract obstruction.

Project description:Left ventricular outflow tract obstruction (LVOTO) complicated with unstable angina (uAP) has not been described widely, but patients with these two conditions have several problems. Differentiation of the two conditions is also often difficult because the chest symptoms are similar. Moreover, nitrates are commonly used for ischemic heart disease, but have the effect of worsening LVOTO. We experienced three cases of dynamic LVOTO with a sigmoid-shaped septum, and without typical hypertrophic obstructive cardiomyopathy, that were complicated with uAP. In all cases, LVOTO was improved after initial percutaneous coronary intervention (PCI) for the left anterior descending artery lesion. Next, a dobutamine stress test was performed and LVOTO was provoked again in two cases, but not in a case with small acute myocardial infarction of the basal septum during PCI. All cases remained asymptomatic with beta-blocker therapy. Therefore, PCI and beta-blocker administration for LVOTO with uAP resulted in favorable clinical courses in all three cases. These outcomes suggest that revascularization including PCI should have priority in the therapeutic strategy for a case of acute coronary syndrome with LVOTO.

Female Fabry Patient With Left Ventricular Outflow Tract Obstruction.

Project description:BackgroundCardiac involvement in Fabry disease is usually characterized by left ventricular hypertrophy (LVH) without obstruction at rest.Case summaryA 59-year-old female patient with progressive chest tightness misdiagnosed as having hypertrophic cardiomyopathy due to LVH with obstruction was finally diagnosed with Fabry disease. Echocardiography showed LVH with severe obstruction, "binary sign," papillary muscle hypertrophy, and depressed longitudinal strain in the basal inferolateral region. The patient felt chest tightness worsened 1 year after receiving enzyme replacement therapy. Percutaneous endocardial septal radiofrequency ablation was performed to relieve obstruction.DiscussionIt is rare for women with Fabry disease to present with severe symptoms, but it is possible. LVH with obstruction should not be a potential point of view to relax the vigilance of Fabry disease. Percutaneous endocardial septal radiofrequency ablation may help to relieve left ventricular outflow tract obstruction in Fabry disease.Take-home messagePaying attention to echocardiographic characteristics is helpful for the identification of Fabry disease.

An unusual cause of left ventricular outflow tract obstruction.

Project description:Left ventricular outflow tract obstruction (LVOTO) has been reported with bio-prosthetic and mechanical mitral valves (MV), though it is more common with the former. The obstruction can be dynamic or fixed. We hereby report a case of fixed LVOTO following bio-prosthetic MV replacement (MVR).

Exaggerated myocardial torsion may contribute to dynamic left ventricular outflow tract obstruction in hypertrophic cardiomyopathy.

Project description:AimsDynamic left ventricular (LV) outflow tract obstruction (LVOTO) is associated with symptoms and increased risk of developing heart failure in hypertrophic cardiomyopathy (HCM). The association of LVOTO and LV twist mechanics has not been well studied in HCM. The aim of the study was to compare the pattern of LV twist in patients with HCM associated with asymmetrical septal hypertrophy with and without LVOTO.Methods and resultsEchocardiography (including speckle tracking) was performed in 212 patients with HCM, divided according to the absence (n = 130) or presence (n = 82) of LVOTO (defined as peak pressure gradient ≥30 mmHg either at rest and/or with Valsalva manoeuvre). Patients with LVOTO were older, had smaller LV dimensions, a higher LV ejection fraction (LVEF), a longer anterior mitral valve leaflet length, and a higher early transmitral pulsed wave to septal tissue Doppler velocity ratio (E/E'). A univariate analysis showed that peak twist was significantly higher in patients with LVOTO compared with patients without LVOTO (19.7 ± 7.3 vs. 15.7 ± 6.0, P = 0.00015). Peak twist was similarly enhanced in patients with LVOTO, manifesting only during Valsalva (19.2 ± 5.6, P = 0.007) and patients with resting LVOTO (19.9 ± 8.0, P = 0.00004) compared with patients without LVOTO (15.7 ± 6.0). A stepwise forward logistic regression analysis showed that LVEF, LV end-systolic dimension indexed to body surface area, anterior mitral valve leaflet length, E/E', and peak twist were all independently associated with LVOTO.ConclusionThis study demonstrates that increased peak LV twist is independently associated with LVOTO in patients with HCM. Peak twist was similarly exaggerated in patients with only latent LVOTO, suggesting that it may play a contributory role to LVOTO in HCM.

Malignant Left Ventricular Outflow Tract Obstruction: A Reason to Operate?

Project description:A 57-year-old man with high-grade synovial sarcoma was found to have cardiac involvement of his malignancy. Intracardiac tumor resulted in dynamic left ventricular outflow tract obstruction and severe mitral regurgitation. He underwent mitral valve replacement and had no cardiovascular symptoms at 1-year follow-up. (Level of Difficulty: Intermediate.).
