The patient was a 53-year-old individual with no relevant past medical history. Preoperative imaging demonstrated severe aortic valve stenosis without associated aortic regurgitation and dilatation of the ascending aorta to a maximum diameter of 49 mm. In addition, a…

Introduction Aneurysm of the right atrial appendage (RAA) is an extremely rare cardiac malformation, typically congenital, although it may also result from right atrial overload due to conditions such as pulmonary hypertension, a patent foramen ovale, or right heart…
The authors present a video of a surgical approach to repair a large right coronary artery (RCA) aneurysm associated with a coronary sinus fistula in a 51-year-old woman. They recommend not simply ligating the fistula, as the ligation could cause an abrupt decrease in coronary flow in the dilated coronary artery, leading to thrombosis and…

Diaphragm Pacing (DP) DP electrically stimulates the diaphragm at phrenic nerve motor end points to stimulate diaphragm contraction, improving and preserving diaphragm function in patients with phrenic nerve injury (PNI) and diaphragm dysfunction (DD). Indications Early investigations reserved DP…
In this special guest lecture for the 2026 Society of Thoracic Surgery of Thailand, Dr. Vince Gaudiani addresses essential surgical techniques for the safe removal of transcatheter aortic valves and their replacement with surgical aortic valves. Dr. Vince Gaudiani discusses the optimal approach for making the aortic incision. He presented his technique known as the…

Clinical Presentation and Preoperative Course A 32-year-old female with a medical history of polycystic ovary syndrome (PCOS), smoking, and a body mass index (BMI) of 32 presented with positional chest pain that had been present for three weeks. An…
Introduction Surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR) are associated with postoperative conduction abnormalities necessitating permanent pacemaker implantation (PPMI). Stress on the conduction system seems to be a major cause of this complication (1, 2). Modified aortic valve replacement (MAVR) aims to lessen the trauma on the conduction system by applying…

The authors present a case of a minimally invasive left atrial myxoma resection performed via a biatrial approach with an inverted T-incision (1). The patient was a 73-year-old woman presenting with exertional dyspnea, fatigue, and dizziness. Transthoracic echocardiography…
In this remarkable interview, CTSNet Editor-in-Chief Joel Dunning spoke with Dr. John Forrest, a cardiologist and Director of both Interventional Cardiology and the Structural Heart Disease Program at Yale Medicine, New Haven, CT, USA, about a paper he authored titled “Six-Year Outcomes After Transcatheter vs Surgical Aortic Valve Replacement in Low-Risk Patients With Aortic Stenosis,”…

Recent trials, including CALGB and JCOG0802, have established the noninferiority of sublobar resection compared to lobectomy for early-stage non-small cell lung cancer (NSCLC) patients with tumors less than two centimeters (1, 2). As such, segmentectomy procedures are becoming more…

In this video, the authors demonstrate a robotic right upper sleeve lobectomy with a rotational azygos vein flap. The patient was a 68-year-old female presenting with a right supra-hilar non-small cell lung cancer, which caused obstructive atelectasis of the…

This video demonstrates a video-assisted thoracoscopic surgery (VATS) right S1 segmentectomy with 3D reconstruction planning, detailing the anatomy of the bronchus, artery, and vein, followed by lines of division depicted in 3D. Further position of the patient, the apical…
An 8-month-old boy with a functional single ventricle secondary to double outlet right ventricle with severe pulmonary stenosis and hypoplastic left ventricle was deemed unsuitable for biventricular repair at this stage. Due to progressive cyanosis, he was offered a bidirectional cavopulmonary anastomosis (bidirectional Glenn), and because of the lack of previous surgical interventions, it was…
A 3-week-old, 2.6-kg infant with d-transposition of the great arteries and an intact ventricular septum had an abnormal left coronary artery (LCA) originating from the left-facing sinus with ostial stenosis and an intramural retro-commissural course. The patient presented with profound cyanosis and persistent pulmonary hypertension, which required 3.5 days of veno-arterial extracorporeal membrane oxygenation, followed…
This video documents the investigation and treatment of a male patient who was referred with severe aortic valve stenosis. He was initially referred for consideration of transcatheter aortic valve replacement (TAVR). However, when the interventional cardiologist analyzed the aortic valve using 3mensio software, which is one of the most common ways to assess patients prior…

This video demonstrates a tailored reparative strategy for a 58-year-old male who presented with severe symptomatic mitral regurgitation due to a flail posterior leaflet with marked myxomatous degeneration. Preoperative transesophageal echocardiogram (TOE) revealed excessive posterior leaflet height (>24 mm)…
