Key result
Isolated LV apical hypoplasia is not benign, causing overt symptoms in ~70% of cases.
- n=59
Why the study?
Isolated Left Ventricular Apical Hypoplasia was historically considered a benign condition of asymptomatic adults, but its hemodynamic behavior under physiological stress remains poorly characterized.
Population
Two distinct clinical cases and 59 cases from the literature
Design
Case reports and PRISMA-guided comprehensive literature review

Implication
Challenges benign ILVAH assumption; supports stress-period monitoring but leaves prospective validation open.
Key Points
- To redefine the clinical spectrum and hemodynamic vulnerability of isolated left ventricular apical hypoplasia across physiological stress states.
- Literature search of the PubMed/MEDLINE database up to February 2026 adhering to PRISMA guidelines (n = 59).
- Analysis of clinical presentation, imaging, and maternal-infant outcomes in two institutional illustrative cases and reported literature cohorts.
- In an infant with apical muscular ventricular septal defects, transient systolic heart failure presented at one month with an LVEF of 45% and NT-proBNP of 2317 ng/L, recovering to an LVEF of 59% at one year after medical therapy.
- Adult pregnancy analysis identified a consistent pattern of severe postpartum acute heart failure and pulmonary edema triggered by rapid peripartum volume shifts.
Structured PICO
P
Population
59 patients (median age 26 years, 45% female) with Isolated Left Ventricular Apical Hypoplasia, analyzed to redefine the clinical spectrum of the disease.
O
Outcome
Clinical presentation, morphological anomalies, therapeutic management, and maternal outcomes during pregnancy in patients with ILVAH.
ILVAH is a stress-sensitive restrictive congenital heart disease with a significant risk of heart failure and arrhythmias, particularly during physiological stressors like pregnancy, challenging its historical classification as a benign anomaly.
Limitations
- Derived entirely from case reports and small case series, which are intrinsically susceptible to publication bias.
- Severe, symptomatic presentations or acute decompensations are likely overrepresented in the literature.
- Precludes the determination of strict causal relationships between the anatomical anomaly and all reported clinical events.
Cite This Study
Pasquinucci et al. (2026) conducted a review in Isolated Left Ventricular Apical Hypoplasia (ILVAH) (n=59). Isolated Left Ventricular Apical Hypoplasia was evaluated. Isolated Left Ventricular Apical Hypoplasia is not a universally benign anomaly, with 69.5% of reported cases developing overt clinical symptoms such as heart failure or arrhythmias.
