AI Article Synopsis

  • A 55-year-old man with hypertrophic obstructive cardiomyopathy and heart failure symptoms had cardiac catheterization, showing a significant 60 mmHg pressure drop across the left ventricular outflow tract.
  • He exhibited symptoms like a double-peaked pulse (pulsus bisferiens) and absent postextrasystolic potentiation, indicating specific heart function issues.
  • The patient was treated with optimized medical therapy and an intracardiac defibrillator; the catheterization helped both diagnose and understand the underlying heart condition better.

Article Abstract

: A 55-year-old gentleman with hypertrophic obstructive cardiomyopathy and heart failure symptoms underwent cardiac catheterization, which confirmed a significant pressure drop (60 mmHg) across the left ventricular outflow tract, a double-peaked pulse (pulsus bisferiens) and an absent postextrasystolic potentiation (Brockenbrough-Braunwald-Morrow sign) in the left ventricular outflow tract and the aorta. He was treated with medical therapy optimization and intracardiac defibrillator implantation. Cardiac catheterization may provide characteristic clues not only to diagnose obstructive hypertrophic cardiomyopathy, but also to understand its pathophysiological correlates.

Sustained myocardial hypertrophy or left ventricular hypertrophy (LVH) triggered by pressure overload is strongly linked to adverse cardiovascular outcomes. Here, we investigated the clinical relationship between serum HSP90α (an isoform of HSP90) levels and LVH in patients with hypertension or aortic stenosis (AS) and explored underlying mechanisms in pressure overload mouse model. We built a pressure overload mouse model via transverse aortic constriction (TAC).

Background: In obstructive hypertrophic cardiomyopathy, myectomy improves symptoms, quality of life, and left ventricular (LV) outflow tract gradients. We prospectively evaluated the temporal changes in various echo parameters after myectomy.

Methods And Results: In 173 adults with obstructive hypertrophic cardiomyopathy (53±10 years, 63% men) who underwent myectomy between March 2017 and June 2020, clinical and blinded echo assessment (before and at 12±6 months follow-up) was performed prospectively (SPIRIT-HCM [Quality of Life and Functional Capacity Following Septal Myectomy in Obstructive Patients With Hypertrophic Cardiomyopathy]).

The 2020 American Heart Association Guidelines advise not to perform mitral valve replacement (MVR) during septal myectomy (SM) to alleviate outflow obstruction. This study aims to review outcomes after concomitant mitral valve (MV) intervention versus SM alone. We conducted a comprehensive literature search across Embase, PubMed, and Scopus.

Introduction: Intranasal mometasone and oral montelukast have been found to be effective for adenoid hypertrophy in children. We aimed to compare the efficacy of combination therapy of mometasone and montelukast versus mometasone alone for adenoid hypertrophy in children.

Methods: Following PRISMA guidelines, we systematically searched PubMed, Embase, Cochrane CENTRAL, and ClinicalTrials.

Stress/Takotsubo cardiomyopathy (TCM) is a transient regional left ventricular (LV) systolic dysfunction, often mimicking acute myocardial infarction with normal coronary arteries. Rarely TCM can mimic hypertrophic cardiomyopathy (HCM). We describe a case where TCM presented with LV hypertrophy (LVH) and left ventricular outflow tract obstruction (LVOTO) which resolved on follow-up.
