Hypertrophic cardiomyopathy (HCM) is a hereditary heart disease with a high risk for sudden cardiac death in young people. As a subtype, hypertrophic obstructive cardiomyopathy (HOCM) additionally has a left ventricular outflow gradient, showing stronger symptoms and requires a different treatment compared with hypertrophic nonobstructive cardiomyopathy (HNCM). In this study our aim was to investigate the regulation of mitochondrial and cardiac remodeling associated long noncoding RNAs (lncRNAs) in blood of patients affected with HOCM and HNCM. We included 28 HNCM, 57 HOCM, and 26 control inviduals. Already known mitochondrial and cardiac remodeling associated lncRNAs uc004cos.4, uc004coz.1, uc004cov.4, uc011mfi.2, uc022bqw.1, uc022bqs.1, and uc022bqu.1 were amplified in serum of these patients and correlated with clinical parameters. Long noncoding RNAs uc004cov.4 and uc022bqu.1 were significantly increased in patients with HOCM but not in patients with HNCM. With the use of receiver operator characteristic (ROC) curve analysis, lncRNAs uc004cov.4 and uc022bqu.1 were able to identify HOCM patients. In our study we evidenced that the specific mitochondrial long noncoding RNAs uc004cov.4 and uc022bqu.1 were upregulated in patients with HOCM and they were also able to identify HOCM and could be developed as useful clinical biomarkers in the future.

Hypertrophic cardiomyopathy is the most common genetic disease of the heart. We report a rare case of hypertrophic obstructive cardiomyopathy mimicking an acute anterior myocardial infarction associated with sudden cardiac death. The patient presented with acute ST elevation myocardial infarction and significant elevation of cardiac enzymes. Cardiac catheterization showed some atherosclerotic coronary artery disease, without significant stenosis. Echocardiography showed left ventricular hypertrophy with a left ventricular outflow tract obstruction; the pressure gradient at rest was 20 mmHg and became severe with the Valsalva maneuver (100 mmHg). There was no family history of sudden cardiac death. Six days later, the patient suffered a syncope on his way to magnetic resonance imaging. He was successfully resuscitated by ventricular fibrillation.

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.

Hypertrophic obstructive cardiomyopathy іs a relatively common condition and one of the most common causes of sudden cardiac death in young age. One of the options for the surgical treatment of this pathology is septal myoectomy, which has been the gold standard for decades. However, despite this, surgical treatment is intended for young patients with a low risk of postoperative complications, while patients with concomitant diseases and a higher surgical risk require alternative treatment. Today, alcohol septal ablation is considered an effective, minimally invasive method for treating hypertrophic obstructive cardiomyopathy in patients with a left ventricular outflow tract gradient ≥ 50 mm Hg. The article presents the experience of using alcohol septal ablation in 57 patients with obstruction of the left ventricular outflow tract. Key words: alcoholic septal ablation, hypertrophic cardiomyopathy, left ventricular outflow tract obstruction.

Abstract Objective This study aimed to evaluate the correlation of circulating long noncoding RNAs (lncRNAs) expression with disease risk, severity, inflammatory cytokines levels and prognosis in patients with sepsis. Methods Differential expression profiles of lncRNA in the serum of sepsis rats were screened by high-throughput transcriptome sequencing. Homologous lncRNAs in the upregulation group were identified by homology analysis in rats and humans. The expression differences of these homologous lncRNAs in the serum of 176 sepsis patients and 176 healthy controls (HCs) were detected using reverse transcription quantitative polymerase chain reaction (RT-qPCR). And inflammatory cytokines levels were detected by enzyme-linked immunosorbent assay (ELISA). A receiver operating characteristic (ROC) curve was used to verify the diagnostic and prognosis values. Spearman correlation coefficient was used to analyze the correlation between the variables. Follow-up was performed to observe the 28-day mortality. Results Among the screened differentially up-regulated lncRNAs, only two lncRNAs were homologous in rats and humans, which in human named PKN2-antisense RNA 1 (PKN2-AS1) and AC068888.1, respectively. Those two lncRNAs were significantly increased in patients with sepsis compared with those in HCs (P < 0.001), in patients with septic shock compared with those no septic shock (P < 0.001), and in non-survivors compared with survivors (P < 0.001). And those two lncRNAs were positively correlated with sepsis-related organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACHE) II score, lactate (Lac), c-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in sepsis patients. Likelihood ratio forward stepwise multivariate logistic regression analysis revealed that high lncRNA AC068888.1 expression was an independent risk factor for septic shock (P < 0.001) and unfavorable prognosis (P = 0.006), but high lncRNA PKN2-AS1 expression was only for unfavorable prognosis (P = 0.019). The ROC curve exhibited a significant predictive value for sepsis risk with area under the curve (AUC) values of 0.879 and 0.842, respectively. For predicting septic shock risk, combining lncRNA AC068888.1 with SOFA score and Lac level, the ROC curve analysis significantly improved the predictability (AUC = 0.882). For predicting 28-day death risk, combining those two lncRNAs with SOFA and APACHE II scores, the ROC curve analysis also significantly improved the predictability (AUC = 0.860). The Kaplan–Meier curves indicated that the survival probability was much worse with those two lncRNAs high expression compared to low expression in patients with sepsis (P < 0.001). Conclusion The circulating absolute expression levels of lncRNA PKN2-AS1 and AC068888.1 in the serum may be used for the early diagnosis, clinical severity evaluation and prognosis of sepsis.

Maximal Medical Therapy

In symptomatic patients with an obstructive variant of hypertrophic cardiomyopathy and no response to maximal medical therapy, we recommend a septal myectomy. It is considered the gold standard for treatment of the basal variant of hypertrophic cardiomyopathy. It has several advantages over alcohol septal ablation, such as the immediate relief of the obstruction and the ability to reduce the septal thickness significantly, to eliminate the potential for midventricular obstruction, and to rule out any other etiologies of left ventricular outflow tract obstruction, which include the presence of abnormalities in the mitral valve subvalvular apparatus such as the presence of anomalous chords, which occured in the current case, and anomalous papillary muscles. In experienced hands, the technique is safe and is associated with excellent outcomes with improved quality of life and potential for survival benefit.

Background: Hypertrophic cardiomyopathy is highly heterogeneous with a diverse anatomy, pathophysiology, and clinical course. It is obstruction to left ventricular outflow that has become the major hallmark of the disease. Septal myectomy has been the gold standard treatment for the relief of left ventricular outflow tract obstruction and cardiac symptoms in both adults and children with obstructive hypertrophic cardiomyopathy. Objective of the study was to evaluate effect of Myomectomy and its impact on survival for a period of one year.Methods: The study design is a retrospective record based observational study. Data was retrieved from previous records both electronic as well as manual records of all the patients who underwent myectomy with or without concomitant procedures such as mitral valve replacement or aortic valve replacement or coronary artery bypass surgery during 2014 to 2018.Results: Majority of the patients 11 (52.4%) in fourth decade i.e. 40-59 years age group. majority were males i.e. 16 (76.2%) and remaining 5 i.e. 23.8% were females. Male to female ratio was 3.2:1. Dyspnoea was present 81% and chest pain in 76.2%. Preoperative LVOT gradient was 86.86±20.33 and post-operative gradient was 23.47±20.49.Conclusions: Operative techniques have evolved from simple myotomy to the present method of extended septal myectomy which can be done in all adult cases of hypertrophic obstructive cardiomyopathy.

AbstractAneurysmal surgeries are high-risk procedures due to potential for occurrence of fatal perioperative complications. This risk is exaggerated in the presence of co-existing hypertrophic cardiomyopathy (HCM). It involves asymmetrical hypertrophy of left ventricle with mitral valve dysfunction, leading to left ventricular outflow tract obstruction. Various perioperative factors may precipitate this obstruction resulting in life-threatening consequences. We report the management of a patient with HCM undergoing anterior communicating artery aneurysm clipping and discuss the anesthetic concerns. Comprehensive approach with careful drug selection, vigilant monitoring, and preparedness for complications enabled patient safety and a good neurological outcome.
