Patients were followed up and their outcomes were studied to document their short and long term outcomes.</p><p class="abstract"><strong>Methods:</strong> It is a retrospective observational study of patients diagnosed with DCRV in a tertiary care hospital in India. The diagnosis of DCRV was based on the following criteria: an echocardiographic diagnosis of DCRV with doppler evidence of a mid ventricular gradient; cardiac catheterization revealing a systolic pressure gradient between right ventricular inflow and outflow tracts; a right ventricular angiogram demonstrating an anomalous muscle bundle causing obstruction well below the infundibulum. All the patients were followed up for their long term outcomes.</p><p class="abstract"><strong>Results:</strong> All the patients underwent echocardiography and cardiac catheterization for confirmation of the diagnosis. Sixty percent of our patients presented during adulthood, which is very unusual presentation of this disease entity. Median age of our patient cohort was 23.5 years. Patients presenting during adulthood have atypical symptoms. Dyspnea was the most common presenting symptom in this study. Right ventricular hypertrophy (73.3%)and right bundle branch pattern (26.6%) were the common electrocardiographic findings in our patients. DCRV is commonly associated with other anomalies. Ventricular septal defect (VSD) was the commonest associated anomaly, which was seen in 80% of our patients. Mean gradient cross the anomalous muscle bundle was 67.5 mmHg. Three of our patients (20%) had no associated anomaly, which is very rare in DCRV. Eight patients underwent surgical correction with significant reduction in gradients in all and no perioperative mortality. Median follow up of 8 years showed no adverse outcomes and no progression of gradients.</p><p class="abstract"><strong>Conclusions:</strong> This study describes in detail the clinical profile, echocardiographic and angiographic identification of anomalous muscle bundles in DCRV patients, which will help the young readers in identifying this often missed diagnosis. It highlights the unusual presentation during adulthood with atypical symptoms in DCRV patients with excellent long-term outcomes on follow up.</p>}, number={7}, journal={International Journal of Research in Medical Sciences}, author={Bhatia, Kaku Singh and George, Oommen K. and Alex, Anoop George}, year={2019}, month={Jun.}, pages={2558–2562} }
