Files Flores R, Mané F, Antunes N, Pereira VH. Apical hypertrophic cardiomyopathy, are low-risk patients really at low risk? A case report. Eur Heart J Case Rep 2020; 4:1-4. [PMID: 33204988 PMCID: PMC7649509 DOI: 10.1093/ehjcr/ytaa316] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Revised: 06/05/2020] [Accepted: 08/13/2020] [Indexed: 11/16/2022]
Abstract
Background Hypertrophic cardiomyopathy (HCM) is a genetically determined myocardial disease that constitutes the main cause of sudden cardiac death (SCD) in young athletes. Apical HCM (ApHCM) represents a complex subset of patients, whose risk of SCD seems not negligible. Most applied scores likely underestimate the risk of heart events in this subset of patients. Case summary We report the case of a 55-year-old man who was admitted in the emergency department after an episode of aborted sudden death due to ventricular fibrillation. The electrocardiogram made at admission was noted for atrial fibrillation and a new-onset left bundle branch block. Emergency coronary angiography was normal. The electrocardiogram was repeated and showed symmetrical and profound inversion of T waves in the lateral leads. Transthoracic echocardiogram and cardiac magnetic resonance revealed left ventricular apical hypertrophy suggestive of apical variant of HCM. A cardiac defibrillator was implanted for secondary prevention of SCD. After 6 months of follow-up no further rhythmic events were noted. Discussion Although low, the risk of SCD of ApHCM patients is not negligible. This case illustrates the need for searching of new predictors of rhythmic risk in patients with ApHCM.

Abstract
A 26-year-old woman with a diagnosis of congenital heart disease was admitted to the hospital with exertional dyspnea, cyanotic complexion, and bilateral lower limb edema. All tests revealed isolated severe right ventricular hypertrophy. She was in poor condition, with a diminishing chance for routine surgical treatment, so she was scheduled for orthotopic homologous heart transplantation. After the operation, isolated severe right ventricular hypertrophic cardiomyopathy was confirmed histologically and pathologically. After the operation, the patient's cardiac function was normal. Exertional dyspnea, cyanotic complexion, and bilateral lower limb edema all improved postoperatively.
