In multivariable analysis, lower PVR (p = 0.02) was identified as an independent predictor of RFPH reduction following sildenafil therapy. Conclusion Sildenafil therapy can support PH reduction in systolic HF patients uneligible for HTx due to RFPH. Lower baseline PVR was identified as an independent predictor of PH reversibility with sildenafil enabling restoration of HTx candidacy.Introduction In case of gastrointestinal diverticula, the duodenal type is quite frequent; duodenum is the second most common site for diverticula following the colon (Glener et al., 2016). However, duodenal diverticular perforation is rare, so the appropriate surgical treatment for this condition is yet unclear (Simoes et al., 2014). This literature has been written in line with the SCARE criteria (Agha et al., 2018). Presentation of case A 94-year-old woman emergently presented to our department with diffuse abdominal tenderness and guarding, indicating pan-peritonitis. Computed tomography revealed pneumoretroperitoneum; Therefore, gastrointestinal perforation was suspected. Emergency surgery was performed; we detected the perforated diverticulum located at the posterior wall of the duodenum with accompanying inflammation. Considering the location, postoperative leakage, and the patient's advanced age, we placed trans-section on duodenal wall against the lesion and resected the diverticulum, The lumen was then manually sutured from within. The anterior wall was closed using linear staplers. The patient recovered uneventfully and was discharged 24 days after surgery. Discusssions As perforated duodenal diverticulum
