Postoperative radiotherapy for breast cancer may be associated with cardiotoxicity. We present a case of acquired infundibular pulmonary stenosis that developed 43 years after radiotherapy for left breast cancer, which necessitated a right ventricular outflow tract myectomy.

Alcohol septal ablation (ASA) is an effective semi-invasive alternative to surgical myectomy in selected patients for the management of severely symptomatic and drug-refractory hypertrophic obstructive cardiomyopathy (HOCM). One contraindication of this procedure is the presence of collateral flow originating from the target septal perforator to a remote myocardial territory. In such circumstances, ethanol injection could cause remote non-target myocardial necrosis in the collateralized territory. Percutaneous revascularization of the collateralized vessel prior to ASA might cope with this contraindication by restoring normal antegrade flow in the occluded artery...

BACKGROUND: Treatment for neglected or recurred congenital muscular torticollis should be differentiated from primary patients due to the long-standing adjacent tissue contracture. The aim of this study was to evaluate the effect of acellular dermal matrix (ADM) on surgery of recurred and neglected patients of congenital muscular torticollis. METHODS: Forty-nine patients were included in the study. All patients underwent resection at the distal end of the sternocleidomastoid muscle...

Septal reduction therapy (SRT) is the accepted therapeutic option for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). At this time, surgical septal myectomy is the gold standard method, but alcohol septal ablation is an acceptable alternative treatment for patients with suitable anatomy. Endocardial septal ablation (ESA) therapy is a little-known method of SRT. Presently described is case of successful ESA procedure performed for HOCM.

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 due to the effect of systolic anterior motion (SAM). AIM: To present the early results of surgical treatment provided to HOCM patients and to compare the effectiveness of two surgical procedures: isolated myectomy and myectomy combined with mitral valve replacement...

OBJECTIVES: Current nonpharmacological therapies for symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM), including septal myectomy and alcohol septal ablation (ASA), carry significant risks for serious cardiac conduction abnormalities. We present a review of the currently available published data regarding the novel use of the relatively low-risk MitraClip® system in the treatment of symptomatic patients. METHODS: Data were collected from 4 separate studies on the use of the MitraClip on 15 symptomatic HOCM patients with systolic anterior motion (SAM) of the mitral valve apparatus...

A 60-year-old man presented with a 10-month history of of stereotypical spells characterized by vertigo, tinnitus, blurred vision, left hemibody numbness, and occasional syncope, precipitated by turning his head leftwards. Cerebral angiography and CT angiography of the head and neck with provocative maneuvers did not demonstrate vertebral artery narrowing. However, there was narrowing of the left internal jugular vein due to extrinsic compression from the sternocleidomastoid with leftward head rotation in the setting of hypoplasia of the right internal jugular vein...

Currently, two therapeutic options are available for patients with drug-resistant obstructive hypertrophic cardiomyopathy. While there is a tendency in extended myectomy to perform a larger septal reduction to eliminate left ventricular outflow tract gradient more effectively, there has been a trend in recent years toward using lower dosages of alcohol during alcohol septal ablation (ASA) to reduce the risk of arrhythmic complications. We report a case of a symptomatic patient with severe septal hypertrophy who underwent an extended ASA of three septal branches...

Background Hypertrophic cardiomyopathy is a genetic disease of the myocardial sarcolemma characterized by left ventricular hypertrophy. When obstruction to the left ventricular outflow tract is present and symptoms are refractory to medication, surgical myectomy or alcohol septal ablation is indicated. Case Description We report a case of a patient presented for myectomy due to recurrence only 1 year after alcohol ablation. Interesting findings were a firm subaortic membrane and a direct insertion of the papillary muscle into the mitral valve...

Background Transarterial valve intervention (TAVI) is valuable in high-risk patients, however, in case of left ventricular outflow tract (LVOT) obstruction, conventional surgery, including partial myectomy, is indicated. Case Description An 84-year-old female patient presented with increasing fatigue after TAVI in 2012, demonstrated a narrowed LVOT. Conventional surgery was performed, including removal of the transcathether valve, partial septal myectomy, and implantation of a sutureless valve. The postoperative course was uncomplicated...

PURPOSE: To report the causes of persistent inferior oblique (IO) overactions after disinsertion procedure. METHODS: Surgical findings of nine eyes of eight patients who needed secondary surgery to the IO muscles because of persistent overaction after IO disinsertion were evaluated retrospectively. Inferior obliques were found partially retracted into their sheath, and some parts of the proximal muscle stumps were found to have established attachments through scar tissues to the sclera in five eyes...

OBJECTIVES: Although septal myectomy is the technique of choice for hypertrophic cardiomyopathy, the surgical management of concomitant mitral valve lesions is controversial. Various complex surgeries have been proposed to address mitral valve lesions. We propose a simple option using an edge-to-edge mitral valve repair through the aortic valve in addition to the septal myectomy. METHODS: We performed an observational analysis of our prospectively collected database...

Hypertrophic cardiomyopathy (HCM) is the most common genetic heart disease, characterised by complex pathophysiology and extensive genetic and clinical heterogeneity. In most patients, HCM is caused by mutations in cardiac sarcomere protein genes and inherited as an autosomal dominant trait. The clinical phenotype ranges from severe presentations at a young age to lack of left ventricular hypertrophy in genotype-positive individuals. No preventative treatment is available as the sequence and causality of the pathomechanisms that initiate and exacerbate HCM are unknown...

PURPOSE: To clarify the efficacy of a surgical strategy based on the superior oblique tendon traction test. METHODS: A retrospective chart review was performed between January 2002 and June 2015. During that period, a single inferior oblique muscle (IO) myectomy and a combined IO myectomy and superior oblique muscle (SO) tuck procedure were performed based on SO tendon looseness as revealed by a traction test. The surgical effects of both procedures and the number of operations were analyzed...

Hypertrophic cardiomyopathy (HCM) is an inherited disease of the heart muscle characterized by otherwise unexplained thickening of the left ventricle. Left ventricular outflow tract (LVOT) obstruction is present in approximately two-thirds of patients and substantially increases the risk of disease complications. Invasive treatment with septal myectomy or alcohol septal ablation can improve symptoms and functional status, but currently available drugs for reducing obstruction have pleiotropic effects and variable therapeutic responses...

Left ventricular (LV) wall thickness is a prognostic marker in hypertrophic cardiomyopathy (HC). LV wall thickness ≥30 mm (massive hypertrophy) is independently associated with sudden cardiac death. Presence of massive hypertrophy is used to guide decision making for cardiac defibrillator implantation. We sought to determine whether measurements of maximal LV wall thickness differ between cardiac magnetic resonance imaging (MRI) and transthoracic echocardiography (TTE). Consecutive patients were studied who had HC without previous septal ablation or myectomy and underwent both cardiac MRI and TTE at a single tertiary referral center...
