Abstract

Left ventricular hypertrabeculation/noncompaction (LVHT) is a cardiac abnormality of unknown etiology. Prenatal diagnosis of LVHT can be established by fetal echocardiography. A review of 106 published cases showed that 46 cases with prenatally diagnosed LVHT were alive 0.5–120 months after birth. Since the course of cases with prenatally LVHT after publication is unknown, we aimed to collect follow-up-information. Information regarding vital status, cardiac and extracardiac morbidity was gathered by contacting the authors of the 46 cases. Fourteen of the 28 authors answered and gave information about 18 cases (six females, seven males, five gender-unknown, age 18 months to 10 years, mean follow-up 60 months). No differences were found between the 18 cases with follow-up and the 28 cases without follow-up regarding age, gender, cardiac or extracardiac comorbidities, and interventions. Three of the 18 cases had died subsequently from heart failure, osteosarcoma, and enterocolitis, respectively. Mutations or chromosomal abnormalities were found in six of the seven examined patients, extracardiac abnormalities in nine patients. Three patients received a pacemaker because of complete AV block, and two patients underwent heart transplantation. Cardiac surgical or interventional procedures were carried out in four patients. None suffered from malignant arrhythmias or had a cardioverter–defibrillator implanted. Based on the limited information, there are indications that cases with fetal diagnosis of LVHT have a continuing morbidity and mortality, even if they receive appropriate care. Since fetal LVHT is frequently associated with genetic abnormalities, further research about survival and underlying genetic causes is needed.
