Delayed Rupture of the Right Sinus of Valsalva into the Right Atrium after Percutaneous Coronary Intervention

Rupture of the sinus of Valsalva is an extremely rare complication after percutaneous coronary intervention (PCI). Because it usually results from the retrograde extension of a dissection of the right coronary artery and may quickly spread to involve the entire aorta, it can cause life-threatening complications such as aortic dissection. If the dissection remains localized, it can resolve spontaneously in the first month. Our patient experienced a delayed rupture of the right sinus of Valsalva into the right atrium at approximately 3 months after PCI

A Case of Synchronous Squamous Cell Carcinoma in the Esophagus and Stomach

Synchronous esophageal and gastric cancers with the pathologic features of a squamous cell carcinoma are extremely rare. A 57-year-old male visited our hospital with a history of hematemesis and was diagnosed with a synchronous cancer. He underwent a staging work-up, and the resectable lesion in the stomach was operated on following radiologic and endoscopic evaluations. The pathologic examination revealed a synchronous cancer consisting of squamous cell carcinoma in the distal esophagus and the cardia of the stomach. We report a case of a synchronous cancer that was successfully treated by surgical resection followed by concurrent chemoradiotherapy. We also discuss the hypothesis regarding the origin and presentation of the synchronous cancer and highlight the importance of careful surveillance by physicians at the time of diagnosis
