Hypertrophic cardiomyopathy is a common inherited cardiac condition where the myocardium progressively thickens in the absence of abnormal loading conditions. Left ventricular hypertrophy often leads to outflow tract obstruction, and this confers significant mortality and morbidity implications. Septal reduction therapies aim to relieve the obstruction in an attempt to reduce the burden of symptoms and potentially improve prognosis. However, both surgical and catheter-based approaches to septal reduction carry risks. At present, international guidelines and expert consensus statements suggest surgical myomectomy is the gold-standard treatment. In this point-counterpoint review, we discuss why in our opinion this recommendation should be reconsidered. We hope to cover the history of catheter based septal reduction therapies and the significant advances made over the last two decades. We also hope to show why we believe the current evidence shows catheter-based alcohol septal ablation is superior to surgical myomectomy.

Higher and prohibitive mitral valve disease surgical scenarios are preferred cases for transcatheter mitral valve replacement as they offer unrelenting mitral valve regurgitation reduction. This review entails medical technologies that are evolving bioprosthetic devices for mitral valve repair and replacement purposes. Transcatheter mitral valve replacement is compared with transcatheter aortic valve implantation based on the etiology and driving factors.

Unlabelled: Septal reduction therapy is an effective treatment for hypertrophic obstructive cardiomyopathy (HOCM). Alcohol septal ablation (ASA) is indicated for HOCM patients who are ineligible for surgical myectomy, but several tips exist for the management of high-risk patients with ASA. Here, we present a case of successful ASA in a HOCM patient with multiple comorbidities, including severe obesity, drug-refractory bronchial asthma, poorly controlled diabetes, and steroid-induced immunosuppression.

Transcatheter edge-to-edge repair (TEER) is approved for patients with symptomatic severe mitral regurgitation (MR) who are deemed inoperable or at high surgical risk with life expectancy of more than 1 year, but has also been used off-label in patients with hypertrophic obstructive cardiomyopathy (HOCM) for symptomatic relief who are not candidates for septal reduction therapy. An 83-year-old woman with decompensated heart failure was found to have HOCM with systolic anterior motion of the mitral valve and a large P2 flail segment with ruptured cords. TEER was performed resulting in mild MR and resolution of the prior left ventricular outflow tract gradient.

Unlabelled: The combination of hypertrophic cardiomyopathy with outflow tract obstruction, severe pre-capillary and post-capillary pulmonary hypertension, and severe primary mitral regurgitation is rare and presents distinct management challenges.
Background And Clinical Significance: Pulmonary hypertension is an independent predictor of all-cause mortality in patients with hypertrophic cardiomyopathy managed medically and often precludes patients from undergoing cardiopulmonary bypass due to increased surgical morbidity and mortality. In studies specifically evaluating surgical myectomy, however, survival is favorable in patients with moderate-to-severe pulmonary hypertension.

Background: Atrial septal defects (ASDs) are a common cause of congenital heart disease worldwide.
Objectives: The purpose of the study was to assess change over time in surgical outcomes for ASD repair and identify patient-level risk factors for adverse postoperative outcomes.
Methods: We analyzed cases of isolated ASD in patients <18 years from 2010 to 2020 from 71 sites participating in the International Quality Improvement Collaborative for Congenital Heart Disease.
