BACKGROUND AND STUDY OBJECTIVE: Different studies have shown a good long-term survival with improvement of symptoms and hemodynamics after percutaneous septal ablation (PTSMA), similar to myectomy considered to be the therapeutic "gold standard" for symptomatic hypertrophic obstructive cardiomyopathy (HOCM). Furthermore, desobliteration of left ventricular (LV) outflow may modify features of the disease considered to be risk-relevant, such as magnitude of LV hypertrophy, outflow gradient, and left atrial (LA) size...

BACKGROUND: Intrinsic abnormalities of the mitral valve are common in patients with hypertrophic cardiomyopathy and may need to be addressed at operation. METHODS: Consecutive patients undergoing transmitral septal myectomy were retrospectively reviewed. The ventricular septum was exposed through a left atriotomy, and the anterior leaflet of the mitral valve was detached from its annulus. An extended myectomy was performed to the base of the papillary muscles. After myectomy, the anterior leaflet was reattached and concomitant mitral valve repair or replacement was performed...

Hypertrophic cardiomyopathy (HCM) is the most commonly inherited cardiac disease-recent studies suggest a prevalence as high as 1 in 200. For symptomatic patients with obstructive HCM who are refractory to medical therapy, septal reduction is indicated. Septal myectomy (SM) is considered the gold standard septal reduction technique. However, due to a shortage of surgeons who are experienced in this technique, alcohol septal ablation (ASA) has overtaken SM as the most commonly performed procedure for obstructive HCM...

Hypertrophic cardiomyopathy is the most common genetic cardiovascular disorder and is associated with symptoms of heart failure and increased risk of sudden cardiac death. The most common condition is obstruction of the left ventricular outflow tract. Surgical septal myectomy and alcohol septal ablation are the 2 accepted modes of septal reduction therapy and are indicated when there are advanced symptoms and a peak left ventricular outflow gradient ≥50 mmHg. Advantages of alcohol septal ablation are limited groin approach, reduction of obstruction of the left ventricular outflow tract and functional improvement, but there are higher chances for intracardiac device implantation and residual obstruction...

BACKGROUND: Subaortic septal myectomy is usually performed to mitigate obstruction in patients with the obstructive form of hypertrophic cardiomyopathy (HCM) or in those with congenital subaortic stenosis. Moreover, it is combined with aortic valve replacement in patients with severe aortic valve stenosis (SAS) and asymmetrical septal hypertrophy causing concomitant left ventricular outflow tract obstruction. When both conditions coexist, it is conceptually difficult to identify a cardiomyopathy beyond an adaptive myocardial hypertrophy, strictly related to pressure overload...

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 all, 236 symptomatic HOCM patients underwent surgical treatment from January 2006 to January 2015. Among them, 86 patients were treated by the classic Morrow myectomy and 150 patients via the modified procedure...

BACKGROUND: In the vast majority of patients with obstructive hypertrophic cardiomyopathy and drug-refractory heart failure, surgical myectomy results in reversal of heart failure symptoms. However, a small patient subgroup fails to experience sustained postoperative improvement despite relief of left ventricular outflow obstruction. Clinical profile of such patients has not been well defined. METHODS: Consecutive obstructive hypertrophic cardiomyopathy patients undergoing myectomy at Tufts Medical Center for drug refractory NYHA III/IV heart failure symptoms, 2004 to 2017, were followed postoperatively for 2...

The Ross procedure offers excellent short-term outcome but the long-term durability is under debate. Reinterventions and follow-up of 100 consecutive patients undergoing Ross Procedure at our centre (1993-2011) were analysed. Follow-up was available for 96 patients (97%) with a median duration of 5.3 (0.1-17.1) years. Median age of the patient cohort was 15.2 (0.04-58.4) years with 76 males. 93% had underlying congenital aortic stenosis. Root replacement technique was applied in all. The most common valved conduits used for reconstruction of the right ventricular outflow tract were homografts (66 patients) and bovine jugular vein (ContegraR) graft (31 patients)...

We applied direct septal echography in transaortic septal myectomy for left ventricular outflow tract obstruction due to hypertrophic obstructive cardiomyopathy and asymmetric septal hypertrophy. A small L-shaped probe was inserted into the right ventricle through a 2-cm incision on the right ventricular outflow tract. The probe was placed directly on the interventricular septum to visualize its actual thickness. It was also helpful to push and expose the septum into a direct field of vision through the aortic annulus...

OBJECTIVES: Patients with hypertrophic obstructive cardiomyopathy (HOCM) and severe left ventricular hypertrophy (maximal left ventricular wall thickness ≥30 mm) are at high risk of sudden cardiac death (SCD). In this study, we aimed to determine whether HOCM patients with severe hypertrophy had a lower incidence of SCD after myectomy. METHODS: HOCM patients with severe hypertrophy were consecutively enrolled from Fuwai Hospital in China between 2000 and 2013...

We present 2 cases of extended septal myectomy using low-cost 3-dimensional (3D) printed models of the interventricular septum with its fragment cut out mechanically or by initial 'virtual' myectomy. 3D prints exhibited excellent cardiac imaging and planning of the 'optimal' volume and shape of the resection, as well as intraoperative quality control of septal myectomy by filling a trough in the 3D-printed interventricular septum with excised myocardium.

The interrupted noneverting mattress suture technique is typically used in conventional surgical aortic valve replacement. The continuous suture technique, although faster, has been associated with a higher incidence of paravalvular leak. Using a slightly modified technique to minimize this risk, we investigated whether continuous suturing would shorten aortic cross-clamp time in aortic valve replacement in comparison with interrupted suturing. We reviewed the cases and compared the perioperative data of 60 consecutive patients in Japan and Australia (35 men and 25 women; median age, 70 yr) who had undergone aortic valve replacement with or without septal myectomy...

Objective: To compare the early clinical effect of septal myectomy and percutaneous transluminal septal myocardial ablation (PTMSA) on the left ventricular outflow obstruction and the rate of complication in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: A total of 204 patients with HOCM who received septal reduction treatment were recruited. These patients were divided into two groups, surgery group (n=135) (65 patients with modified Morrow procedure, 70 patients with non-Morrow myomectomy) and PTMSA group (n=69)...

Emergent ascending aortic replacement and extended myectomy were performed in a woman with acute aortic dissection who was aged 63 years. Preoperative transthoracic echocardiography performed in the intensive care unit showed only slight left ventricular outflow tract (LVOT) obstruction, but intraoperative transesophageal echocardiography after induction of anesthesia revealed pericardial effusion, systolic anterior motion(SAM), and associated mitral regurgitation(MR). Perioperative SAM and MR are sometimes facilitated under various hemodynamic conditions, but in this case, the left ventricular wall was thick and LVOT appeared to be obstructive by a hypertrophied septum...

Surgical septal myectomy is the treatment of choice for patients with symptomatic hypertrophic obstructive cardiomyopathy refractory to medications. This report describes our minimally invasive approach for performing a septal myectomy via a ministernotomy that has been used at our institution for more than a decade. In particular, patient preparation, surgical technique, and clinical considerations are highlighted. Performed properly, this minimally invasive technique is a feasible and effective approach in our experience...

Hypertrophic obstructive cardiomyopathy has been rising in prevalence, due to increased awareness and advanced imaging. For the symptomatic patient, pharmacological management remains an effective approach to the majority of patients with obstructive hypertrophic cardiomyopathy. However, a significant subset fails to improve sufficiently with medical therapy initially, or progressively becomes more symptomatic despite augmented medications over time. Most of the advances in the treatment of obstructive hypertrophic cardiomyopathy have therefore been made in the area of non-pharmacologic management, particularly septal reduction therapy...
