To determine whether the routine use of real‐time transthoracic echocardiographic (TTE) guidance in addition to fluoroscopy would ensure the safety of right ventricular endomyocardial biopsy (RV EMB) in a low‐volume center. RV EMB is a valuable tool and plays an important role in the diagnosis and management of patients with myocardial diseases. However, it has yet to gain widespread acceptance due to its perceived low diagnostic yield and concerns regarding its invasive nature and potential complications. Although the safety of EMB when performed by experienced operators in high‐volume centers is well established, the complication rate in low‐volume centers is less well defined but appears to be higher. This is a retrospective single‐center cross‐sectional study. Consecutive adult patients who underwent RV EMB procedures at Tygerberg Hospital (Cape Town, South Africa) between August 2017 and December 2020 were included. RV EMB was successfully performed in 85 patients. No major complications were reported. Five (5.88%) patients experienced minor complications: three transient right bundle branch blocks and two hemodynamically stable ventricular tachycardia. A definitive biopsy diagnosis was made in 37 (43.54%) patients. The average procedural time was 27.06 min, which equated to 4.09 min per specimen taken. The routine use of real‐time TTE guidance in addition to fluoroscopy ensured the safety of RV EMB in a low‐volume center without unnecessarily prolonging procedural time.
