A device that can evaluate human pulmonary microcirculation is currently unavailable. This study aimed to establish a novel approach for assessing pulmonary microcirculation in patients with pulmonary hypertension (PH). We used a guidewire embedded with temperature and pressure sensors to measure the following pulmonary microcirculatory function indicators: pulmonary flow reserve, pulmonary index of microcirculatory resistance (PIMR), and pulmonary resistive reserve ratio.

However, the risk assessment for new PPI and effective procedural strategy for preventing new PPI in patients with preexisting RBBB are still unclear. This study stratified the new PPI risk after TAVI and investigated the impact of implantation strategy in a preexisting RBBB cohort.

We aimed to clarify the current efficacy, patency, and success rate of BPA for total occlusions.
Methods: Between April 2016 and August 2021, 178 BPAs were performed in 100 patients with CTEPH and total occlusions.
Background: Transcatheter aortic valve implantation (TAVI) is an established treatment for severe aortic stenosis (AS), but despite estimates of life expectancy after TAVI being essential in heart team discussion, these data are scarce. Therefore, the current study sought to assess long-term survival and its trends in relation to chronological age, surgical risk, and treatment period.
Methods and results: We included 2,414 consecutive patients who underwent TAVI for severe symptomatic AS between 2008 and 2021 at 2 international centers.
Membranous septum (MS) length, in conjunction with implantation depth (ID), is known as a determinant of conduction disturbance (CD) after transcatheter aortic valve implantation (TAVI). However, its impact might be dissimilar among valve types because each valve has a different platform. This study sought to investigate the different impacts of ID and MS length on the new-onset CD between ACURATE neo and SAPIEN 3.

Methods: This was a case-cohort analysis of the REAL-CAD study, a randomized trial of high- or low-dose (4 or 1 mg/day) pitavastatin therapy in patients with stable CAD. We examined the MACE risk according to the quartile of hsTnI and NT-proBNP at baseline.
Background: Transcatheter aortic valve replacement (TAVR) has become the dominant treatment strategy for severe aortic stenosis in patients with high and intermediate surgical risk. Although complications are significant cause of increasing mortality after TAVR and bailout techniques have been well established, we still encounter a rare complication without widely accepted bailout option. We present a rare complication of valvuloplasty balloon entrapment to a self-expanding valve strut with successful bailout.

Presentation Of Case: A 72-year-old woman, with a history of multiple abdominal surgeries, underwent laparoscopic surgery for rectal prolapse four years prior. Three 12 mm ports were inserted into the umbilical region, right upper quadrant and right lower abdomen, subsequently, incisional hernias developed at all three sites.
Background: Localized colorectal amyloidosis has a good prognosis, but cases involving bleeding or perforation may require surgery. However, there are few case reports discussing the differences in the surgical strategy between the segmental and pan-colon types.
Case Presentation: A 69-year-old woman with a history of abdominal pain and melena was diagnosed with amyloidosis localized in the sigmoid colon by colonoscopy.
Pulmonary vasodilators have improved pulmonary arterial hypertension (PAH) symptoms and prognosis; however, the drugs cause some side effects, including lower legs pain, which impair quality of life (QOL). The present study examined if compression stockings improved lower extremity symptoms and QOL caused by pulmonary vasodilators in PAH patients. We retrospectively enrolled consecutively ten patients with PAH treated by pulmonary vasodilators, who were regularly followed in Kurume University Hospital from January 2022 to June 2022.

In particular, aortic valve disease causes high morbidity and mortality rates, and sometimes requires surgical aortic valve replacement (SAVR) at a young age. Although transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) in surgical high-risk patients is a well-established treatment, there are few reports of TAVR in MPS and medium- and long-term outcomes are not known.

Objectives: This study sought to investigate mechanisms of anti-hypertensive drugs on improvement of vascular endothelial function in patients with essential hypertension.
Background: During neoadjuvant chemotherapy for giant gastrointestinal stromal tumors, changes in gastrointestinal stromal tumor size are rarely associated with events such as perforation and bleeding that require emergency surgery. Moreover, it is very rare for gastrointestinal stromal tumors to shrink and become mobile, resulting in gastric volvulus. Herein, we report a case of gastrointestinal stromal tumor shrinkage during neoadjuvant imatinib treatment, resulting in gastric volvulus that required surgery.

We evaluated the impact of mild PVR after TAVI on long-term clinical outcomes. We included patients who underwent TAVI for severe symptomatic aortic stenosis between December 2008 and June 2019 at 2 international centers and compared all-cause death between the group with mild PVR (group 1) and the group with none or trace PVR (group 2).

This study aimed to clarify the prevalence of various types of CVDs in cancer patients, using the database of the Cardiovascular Medicine in Kurume University Hospital.
Methods And Results: This retrospective cohort study enrolled 11,093 hospitalized patients in Cardiovascular Medicine, Kurume University Hospital from April 2011 to March 2019.
